Description

{Pulsating heat pipe module including a bridge and manufacturing method thereof}

The present invention relates to a vibrating heat pipe module including a bridge and a method for manufacturing the same, and more specifically, to a vibrating heat pipe module and a method for manufacturing the same, in which a flow plate in which a working fluid channel of the vibrating heat pipe module is formed is formed using a press method, thereby reducing the working time and manufacturing cost and improving productivity.

Recently, interest in heat dissipation has been increasing due to the advancement in performance and miniaturization of electronic devices.

In the past, straight heat pipes (bar type heat pipes) that dissipate heat by utilizing the phase change of the working fluid were mainly used, and this is a method of cooling by circulating the working fluid by utilizing the capillary pumping force of the wick provided inside the heat pipe.

However, conventional heat pipes have a problem in that they cannot be operated in top heating methods due to low capillary force compared to gravity.

Accordingly, recently, interest has been increasing in a pulsating heat pipe that cools a high-temperature section by self-vibrating during the process of circulating a liquid slug-shaped working fluid, which has no wick structure and alternates between liquid and gas phases, in a closed-loop flow path in the form of a slug train.

However, vibrating heat pipes are more difficult to manufacture than conventional heat pipes because their internal paths are complex, and there is a problem that it takes a lot of time and money to manufacture the paths using photolithography methods.

FIG. 2 is an exploded perspective view of the vibrating heat pipe module shown in FIG. 1 from the front. FIG. 3 is an exploded perspective view of the vibrating heat pipe module shown in FIG. 1 from the rear.

Referring to FIGS. 1 and 3, a vibrating heat pipe module according to an embodiment of the present invention includes a euro plate (100), an upper plate (200), and a lower plate (300).

The above euro plate (100), the upper plate (200) and the lower plate (300) are made of metal and are plate-shaped with a preset thickness.

The above metal material is explained as an example of a material such as aluminum or copper, but is not limited thereto and other metals can be used.

The above setting thickness is explained as an example of about 0.5 mm to 3.0 mm.

The above-mentioned euro plate (100), the upper plate (200), and the lower plate (300) are described as being made of the same material and having the same thickness, but are not limited thereto and may be made of different materials and thicknesses.

In this embodiment, the euro plate (100), the upper plate (200), and the lower plate (300) are explained as an example of being processed using the same original plate (B). However, the invention is not limited thereto, and the euro plate (100) may use a first plate that is set in advance, and the upper plate (200) and the lower plate (300) may use a second plate that has a different material or thickness from the first plate.

The above Euro plate (100), the upper plate (200), and the lower plate (300) are all formed using a press. The forming method of the above Euro plate (100), the upper plate (200), and the lower plate (300) will be described in detail later.

In the above-mentioned Euro plate (100), a working fluid channel forming a closed loop Euro is formed.

The above working fluid channel (110) is the entire path through which the working fluid flows when the vibrating heat pipe module is operated. The width, length, shape, etc. of the working fluid channel (110) are designed in advance according to the characteristics of the working fluid.

The above working fluid channel (110) includes a plurality of euro holes (111) and a plurality of euro bridges (112).

The above plurality of euro holes (111) are formed as a plurality of euro patterns that divide the operating fluid channel (110) into multiple parts. That is, the above euro holes (111) are through holes pierced by a press mold in the above euro plate (100).

Referring to FIGS. 2 and 3, in this embodiment, the working fluid channel (110) is described as having at least a portion of a zigzag-shaped flow path. However, the present invention is not limited thereto, and the width, length, shape, etc. of the working fluid channel (110) may be changed differently depending on the characteristics of the working fluid.

The above plurality of euro holes (111) include a working fluid injection hole (111a), a plurality of first euro holes (111b), and a plurality of second euro holes (111c).

The above working fluid injection hole (111a) is a working fluid injection path used when injecting working fluid into the vibrating heat pipe module. The working fluid injection holes (111a) are formed in such a way that three of them are connected to each other by the path bridges (112), as an example. However, the present invention is not limited thereto, and the width, length, and shape of the working fluid injection holes (111a) can be variously changed. The injection port (105) of the working fluid injection hole (111a) is sealed after the working fluid is injected.

The first flow holes (111b) are connected to the working fluid injection holes (111a) by the flow bridge (112). The first flow holes (111b) are formed in a plurality of lengths in one direction (-Y) and spaced apart from each other by a set interval, so as to guide the working fluid in the one direction (-Y). However, the present invention is not limited thereto, and the width, length, and shape of the first flow holes (111b) may be variously changed.

The above first euro holes (111b) and the above second euro holes (111c) are arranged alternately.

The above second flow holes (111c) are formed in the same shape as the first flow holes (111b), as an example. The second flow holes (111c) are connected to the first flow holes (111b) by the flow bridge (112). The second flow holes (111c) are formed in a plurality of lengths in the one direction (-Y), but the working fluid is guided in the opposite direction (Y) to the one direction. However, the present invention is not limited thereto, and the width, length, and shape of the second flow holes (111c) may be variously changed.

The above-described euro bridges (112) are formed by stepwise forging a portion of the remaining portion after processing the plurality of euro holes (111). The thickness of the euro bridges (112) is processed to be about 40% to 80% of the thickness of the euro plate (100). The euro bridges (112) connect the euro holes (111) to each other and serve as a fluid passage through which the working fluid can pass between the euro holes (111).

Referring to Fig. 2, the front surface of the euro plate (100) facing the top plate (200) is provided with a first protrusion (101) protruding in a direction toward the top plate (200).

The above first protrusion (101) is explained as an example in which two are formed at the upper left and right corners on the front side of the euro plate (100). Accordingly, the two first protrusions (101) are inserted into the two first joining holes (201) described later. The first protrusion (101) is pressure-molded using a forming press mold. The first protrusion (101) can guide the assembly position of the euro plate (100) and the upper plate (200). However, the present invention is not limited thereto, and the number, shape, and position of the first protrusion (101) can be applied by changing them in various ways as long as it can guide the assembly position with the upper plate (200).

Referring to FIG. 3, the back surface of the euro plate (100) facing the lower plate (300) is provided with a second protrusion (102) protruding in a direction toward the lower plate (300).

The above second protrusions (102) are explained as two formed at the lower left and right corners on the back surface of the above euro plate (100). Accordingly, the two second protrusions (102) are inserted into the two second joining holes (301) described later. The above second protrusions (102) are pressure-molded using a forming press mold. The above second protrusions (102) can guide the assembly position of the above euro plate (100) and the lower plate (300). However, the present invention is not limited thereto, and the number, shape, and position of the above second protrusions (102) can be applied by changing them in various ways as long as they can guide the assembly position with the lower plate (300).

The above top plate (200) is a flat plate formed in a shape corresponding to the outline shape of the above euro plate (100) so as to be laminated on the upper surface of the above euro plate (100). That is, no euro is formed on the above top plate (200), and it is formed so as to cover the open upper surface of the working fluid channel (110) formed on the above euro plate (100).

A plurality of first coupling holes (201) are punched on at least some of the upper, lower, left, and right corners of the upper plate (200). In this embodiment, the first coupling holes (201) are described as being formed in four numbers on the upper, lower, left, and right corners of the upper plate (200).

The lower plate (300) is a flat plate formed in a shape corresponding to the outline shape of the euro plate (100) so as to be laminated on the lower surface of the euro plate (100). That is, no euro is formed on the lower plate (300), and it is formed so as to cover the open lower surface of the working fluid channel (110) formed on the euro plate (100).

A plurality of second coupling holes (301) are punched on at least some of the upper, lower, left, and right corners of the lower plate (300). In this embodiment, the second coupling holes (301) are described as being formed in four numbers at the upper, lower, left, and right corners of the lower plate (300).

The upper plate (200) and the lower plate (300) are formed with the same thickness and shape, and the first coupling hole (201) and the second coupling hole (301) are formed in the same position, so that they are manufactured in the same way through the same process and are compatible with each other. However, the present invention is not limited thereto, and the upper plate (200) and the lower plate (300) may have the same shape but different thicknesses.

A method for manufacturing a vibrating heat pipe module according to an embodiment of the present invention configured as described above is described as follows.

FIG. 8 is a flowchart showing a method for manufacturing a vibrating heat pipe module including a bridge according to an embodiment of the present invention.

Referring to Fig. 8, a base plate (B) having a preset thickness is shaped into the outline shape of a preset vibrating heat pipe module, and a cover plate to be used as the upper plate (200) and the lower plate (300) is press-formed (S1).

The upper plate (200) and the lower plate (300) are formed using a first press mold (not shown) that is manufactured in advance to shape-process the outline shape of the vibrating heat pipe module.

At this time, when the shape of the upper plate (200) and the lower plate (300) is processed, the first and second joining holes (201) (301) are also pierced.

Since the upper plate (200) and the lower plate (300) are identical plates manufactured in the same process, they are compatible with each other.

Next, a first press forming step is performed to form the euro plate (100) using the above-mentioned disc (B). (S2)

In the first press forming step (S2) described above, the circular plate (B) is shaped into the outline shape of the vibrating heat pipe module, and a plurality of flow path holes (111) are pierced to form the circular plate (B) into the flow path plate (100) through the first press forming.

Figure 4 shows a state in which a plurality of Euro holes are pierced and first press-formed on a Euro plate according to an embodiment of the present invention.

The above-mentioned euro plate (100) is pierced with a euro pattern that divides the working fluid channel (110) of the above-mentioned vibrating heat pipe module into a plurality of euro holes (111) along the flow direction. The working fluid channel (110) and the euro pattern are designed in advance and can be applied by changing them in various ways depending on the characteristics of the working fluid.

In the above first press forming step, since the flow path is pierced, if the working fluid channel is formed as a single flow path hole, there is a problem that the remaining portion is separated and detached after piercing the flow path hole. On the other hand, in the present embodiment, since the working fluid channel (110) is divided into a plurality of flow path holes (111) and pierced, the remaining portion (100a) after piercing the flow path holes (111) in the flow path plate (100) can be prevented from being separated.

The above Euro plate (100) is explained as an example using a second press mold (not shown) that is manufactured in advance so that the above outline shape and the above Euro holes (111) can be processed at the same time.

However, the invention is not limited thereto, and after the shape of the euro plate (100) is processed using the first press mold, it is also possible to pierce the euro holes (111) using a separately manufactured press mold. That is, after a plurality of plates are formed in advance in the outline shape of the vibrating heat pipe module using the first press mold, some of the plates are used as the upper plate (200), some are used as the lower plate (300), and the rest are used as the euro plate (100).

Next, a second press forming step is performed to form the Euro bridge (112) on the Euro plate (100). (S3)

In the second press forming step (S3) described above, a portion of the remaining portion (100a) after piercing processing on the euro plate (100) is step-processed to be thinner than the thickness of the euro plate (100) to form the euro bridge (112).

The thickness of the above Euro bridges (112) is processed to be about 40% to 80% of the thickness of the above Euro plate (100).

The above Euro bridge (112) can be forged using a pre-fabricated forging press mold (not shown).

Fig. 5 is a drawing showing a state in which euro bridges are forged and secondarily press-formed on a euro plate according to an embodiment of the present invention. Fig. 6 is a cross-sectional view of the euro bridge shown in Fig. 5 taken along line A-A.

Referring to FIGS. 5 and 6, the euro bridges (112) are formed stepwise in the remaining portion (100a) after the piercing process, so that the working fluid of the plurality of euro holes (111) can move across the euro bridges (112).

Next, a third press forming step is performed to form an assembly guide part on the above-mentioned Euro plate (100). (S4)

In the third press forming step (S4) described above, the assembly guide part is formed to guide the assembly positions of the euro plate (100) and the upper plate (200), and the euro plate (100) and the lower plate (300).

The above assembly guide part includes a first projection (101) that protrudes from the euro plate (100) to be inserted into the first coupling hole (201) of the upper plate (200), and a second projection (102) that protrudes from the euro plate (100) to be inserted into the second coupling hole (301) of the lower plate (300).

The above first protrusion (101) and the above second protrusion (102) can be formed using a separately manufactured forming press mold (not shown).

Figure 7 is a cross-sectional view of the first protrusion illustrated in Figure 5 taken along the line B-B.

Referring to Fig. 7, the first protrusion (101) is formed to protrude in a direction toward the upper plate (200) by pressing the back surface of the euro plate (100).

The above second protrusion (102) is formed to protrude in a direction toward the lower plate (300) by pressing the front surface of the euro plate (100).

Referring to FIGS. 2 and 3, the first protrusion (101) is formed in two at the upper left and right corners of the front surface of the euro plate (100), and the second protrusion (102) is formed in two at the lower left and right corners of the back surface of the euro plate (100). However, this is not limited to this, and the number, position, and shape of the first and second protrusions (101) (102) can be applied by changing them in various ways.

As described above, the euro plate (100) is formed by forming the euro holes (111), the euro bridge (112), and the assembly guide section through three first, second, and third press forming steps.

When the upper plate (200), the euro plate (100), and the lower plate (300) are made, a cleaning process can be performed to remove foreign substances such as press oil remaining on their surfaces.

Next, the upper plate (200), the Euro plate (100), and the lower plate (300) are sequentially laminated and then joined together to complete the vibrating heat pipe module. (S5)

The first projection (101) of the above Euro plate (100) is fitted into the first coupling hole (201) of the above upper plate (200), and the second projection (102) of the above Euro plate (100) is fitted into the second coupling hole (301) of the above lower plate (300), and then they are coupled together.

The above upper plate (200), the euro plate (100), and the lower plate (200) are joined to each other by brazing, but the present invention is not limited thereto and various methods such as bonding may be used.

As described above, by press forming the working fluid channel (110) of the euro plate (100) through piercing and forging, the work is easier and time and cost can be reduced compared to existing channel forming methods such as etching, so that productivity can be improved. In addition, since chemical solutions used in etching are not used, environmentally harmful factors can be prevented.

Meanwhile, FIG. 9 is a drawing showing euro holes of a euro plate according to a second embodiment of the present invention.

Referring to FIG. 9, the cross-sectional areas of the euro holes (121) formed in the euro plate (100') according to the second embodiment of the present invention are formed differently, and the positions of the euro bridges (122) are formed differently, which are different from those of the first embodiment, and since the remaining configurations and functions are similar, a detailed description of the similar configurations is omitted.

Among the above-described flow path holes (121), the cross-sectional area (D1) of the first flow path hole (121b) and the cross-sectional area (D2) of the second flow path hole (122b) are formed differently. Here, the flow directions of the working fluid in the first flow path hole (121b) and the second flow path hole (121c) are opposite to each other, and the cross-sectional area (D2) of the second flow path hole (121c) through which the working fluid moves upward is formed larger than the cross-sectional area (D1) of the first flow path hole (121b) through which the working fluid moves downward. That is, an example will be described in which the cross-sectional area (D2) of the second flow path hole (121c) is formed larger than the cross-sectional area (D1) of the first flow path hole (121b). The cross-sectional area (D1) of the first euro hole (121b) can be set to a range of 50% to 80% of the cross-sectional area (D2) of the second euro hole (121c).

Among the above Euro holes (121), the operating fluid injection hole (121a) is explained as having the same cross-sectional area as the first Euro hole (121b), but is not limited thereto and may be changed.

The above-mentioned euro bridge (122) can be formed before moving from the first euro hole (121b) to the second euro hole (121c). That is, the euro bridge (122) is not formed at the point where the first euro hole (121b) and the second euro hole (121c) are connected, but is formed on the first euro hole (121b), so that the flow of the working fluid can be made smoother.

The method of forming the above-mentioned Euro plate (100’) is the same as that of the first embodiment, so a detailed description thereof is omitted.

Meanwhile, FIG. 10 is a drawing showing an operating fluid channel of a euro plate according to a third embodiment of the present invention.

The outline shape of the above euro plate (400) is described as being circular, but is not limited thereto, and a polygon or other shape is of course also possible.

The above-described working fluid channel (410) is described as including, for example, a plurality of circular channels spaced apart from each other in the radial direction and having different diameters, and a plurality of radial straight channels formed long in the radial direction to connect the plurality of circular channels and spaced apart from each other in the circumferential direction. However, the present invention is not limited thereto, and various forms of radial channels may be used as the working fluid channel (410).

The euro pattern pierced on the above euro plate (400) is explained as an example of a pattern in which the above circular euros are divided into a plurality of euro holes along the circumferential direction.

The euro bridge (412) of the above euro plate (400) is explained as an example in which a plurality of circular euros are forged and processed at positions spaced apart from each other by a predetermined interval along the circumference of each of the plurality of circular euros.

However, the invention is not limited thereto, and the euro pattern may be set as a pattern that divides the straight euros, and in this case, the euro bridge (412) may be provided in the straight euros.

The method of forming the above-mentioned Euro plate (400) is the same as that of the first embodiment, so a detailed description thereof is omitted.

Meanwhile, FIG. 11 is a drawing showing an operating fluid channel of a euro plate according to a fourth embodiment of the present invention.

Referring to FIG. 11, the operating fluid channel (510) of the euro plate (500) according to the fourth embodiment of the present invention is different from the first embodiment in that it is a spiral-shaped euro, and the remaining configuration, operation, and manufacturing method are the same as those of the first embodiment, so a detailed description thereof is omitted.

The outline shape of the above Euro plate (500) is described as being circular, but is not limited thereto, and a polygon or other shape is of course also possible.

The euro pattern pierced into the above euro plate (500) is a pattern that includes a plurality of euro holes by dividing the spiral euro along a spiral direction.

The euro bridges (512) of the above euro plate (500) are forged in multiple pieces at positions spaced apart from each other in the spiral direction from the above spiral euros.

Since the method of forming the above-mentioned Euro plate (500) is the same as that of the first embodiment, a detailed description thereof is omitted.

Although the present invention has been described with reference to the embodiments shown in the drawings, these are merely exemplary, and those skilled in the art will understand that various modifications and equivalent other embodiments are possible therefrom. Accordingly, the true technical protection scope of the present invention should be determined by the technical idea of the appended claims.
