本發明之再一目的在於提供一種具有液彈管的迴路熱管,其迴流管的液段沒有組裝編織脈管或其他毛細材料的問題,可降低製造成本,並提高良率。Yet another object of the present invention is to provide a loop heat pipe with a liquid-elastic tube.

為了達成上述目的,本發明提供一種具有液彈管的迴路熱管,包含有:一蒸發腔,具有一殼體以及設置於該殼體內的一毛細材,該毛細材不佔滿該殼體內部而與該殼體之間形成一蒸汽空間;一迴流管,具有兩端而分別定義為一汽端以及一液端,該迴流管的汽端係與該殼體連接而與該空間相連通,該迴流管的液端與該殼體連接而與該殼體內部連通;以及一工作液,注入於該蒸發腔;其中,定義該迴流管身部預定長度的部位為一冷凝段,該冷凝段的表面用以設置一散熱單元,定義該迴流管由該冷凝段至該汽端的部分為汽段,以及定義該迴流管由該冷凝段至該液端的部分為液段,該迴流管之液段內部係設有至少一分隔件,而將該迴流管之液段分隔為二以上的液彈管,該二以上液彈管於該迴流管內彼此不相連通,且該二以上液彈管的口徑均小於該迴流管管徑,該二以上液彈管均連通該冷凝段及該殼體內部。In order to achieve the above object, the present invention provides a loop heat pipe with a liquid bomb tube, which includes: an evaporation cavity, a casing, and a capillary material disposed in the casing. The capillary material does not occupy the interior of the casing. A steam space is formed between the shell and the casing; a return pipe having two ends is defined as a steam end and a liquid end, respectively. The steam end of the return pipe is connected to the shell and communicates with the space, and the reflux The liquid end of the tube is connected to the casing and communicates with the interior of the casing; and a working fluid is injected into the evaporation chamber; wherein a portion defining a predetermined length of the return tube body is a condensation section, and the surface of the condensation section Used to set a heat dissipation unit, define the part of the return pipe from the condensation section to the steam end as the steam section, and define the part of the return pipe from the condensation section to the liquid end as the liquid section, and the internal part of the liquid section of the return pipe At least one partition is provided, and the liquid section of the return tube is divided into two or more liquid bomb tubes.

為了詳細說明本發明之技術特點所在,茲舉以下之較佳實施例並配合圖式說明如後,其中:In order to explain the technical features of the present invention in detail, the following preferred embodiments are described in conjunction with the drawings as follows, wherein:
如第1圖至第6圖所示,本發明第一較佳實施例所提供之一種具有液彈管的迴路熱管10,主要由一蒸發腔11、一迴流管21以及一工作液31所組成,其中:As shown in FIGS. 1 to 6, a loop heat pipe 10 with a liquid bomb tube provided by the first preferred embodiment of the present invention is mainly composed of an evaporation chamber 11, a return pipe 21, and a working fluid 31. ,among them:
該蒸發腔11,具有一殼體12以及設置於該殼體12內的一毛細材14,該毛細材14不佔滿該殼體12內部而與該殼體12之間形成一蒸汽空間16。該蒸汽空間16係具有一共室161以及複數支室162,該複數支室162彼此由該毛細材14隔開預定距離,且該複數支室162均連通於該共室161,除了這個連通的部分之外,該複數支室162不在其他部位彼此相通。該毛細材14於本實施例中係為銅粉燒結而成。The evaporation chamber 11 has a casing 12 and a capillary material 14 disposed in the casing 12. The capillary material 14 does not fill the interior of the casing 12 and forms a steam space 16 between the casing 12 and the casing 12. The steam space 16 has a common chamber 161 and a plurality of branch chambers 162. The plurality of branch chambers 162 are separated from each other by the capillary 14 at a predetermined distance, and the plurality of branch chambers 162 are connected to the common chamber 161, except for this communicating portion. In addition, the plurality of branch chambers 162 do not communicate with each other at other locations. The capillary material 14 is sintered from copper powder in this embodiment.
該迴流管21,具有兩端而分別定義為一汽端214以及一液端216,該迴流管21的汽端214係與該殼體12連接而與該空間相連通,該迴流管21的液端216與該殼體12連接而與該殼體12內部連通。The return pipe 21 has two ends and is defined as a steam end 214 and a liquid end 216, respectively. The steam end 214 of the return pipe 21 is connected to the casing 12 and communicates with the space. The liquid end of the return pipe 21 216 is connected to the casing 12 and communicates with the inside of the casing 12.
該工作液31,本實施例以純水為例,注入於該蒸發腔11,被該毛細材14所吸附,並存在於該迴流管21的部分位置。The working fluid 31 in this embodiment takes pure water as an example, is injected into the evaporation chamber 11, is adsorbed by the capillary material 14, and exists in a part of the return pipe 21.
其中,定義該迴流管21身部預定長度的部位為一冷凝段22,該冷凝段22的表面用以設置一散熱單元100,這個散熱單元100在實際實施時可以是複數鰭片。此外,定義該迴流管21由該冷凝段22至該汽端214的部分為汽段24,以及定義該迴流管21由該冷凝段22至該液端216的部分為液段26,該迴流管21的液段26內部設有一分隔件28,而將該迴流管21的液段26分隔為兩個子管體並分別定義為液彈管29,該二液彈管29於該迴流管21的液段26內彼此不相連通,且這兩個液彈管29的口徑均小於該迴流管21的管徑,該二液彈管29都連通該冷凝段22以及該殼體12內部。這個分隔件28在實際製造時可以是板體而與該迴流管21一體成形。該工作液31係位於該迴流管21的液段26中。Wherein, a part of the body of the return pipe 21 with a predetermined length is defined as a condensation section 22, and a surface of the condensation section 22 is provided with a heat dissipation unit 100. The heat dissipation unit 100 may be a plurality of fins in actual implementation. In addition, a portion of the return pipe 21 from the condensation section 22 to the steam end 214 is defined as a vapor section 24, and a portion of the return pipe 21 from the condensation section 22 to the liquid end 216 is defined as a liquid section 26, and the return pipe The liquid section 26 of 21 is provided with a partition 28 therein, and the liquid section 26 of the return pipe 21 is divided into two sub-tube bodies and defined as liquid bomb tubes 29 respectively. The two liquid bomb tubes 29 are disposed on the return pipe 21. The liquid sections 26 are not connected to each other, and the diameters of the two liquid bomb tubes 29 are smaller than the diameter of the return pipe 21. The two liquid bomb tubes 29 communicate with the condensation section 22 and the inside of the casing 12. This partitioning member 28 may be a plate body and integrally formed with the return pipe 21 during actual manufacturing. The working fluid 31 is located in the liquid section 26 of the return pipe 21.
於本實施例中,該分隔件28除了位於該液段26之外,還延伸至該冷凝段22,並且延伸至該冷凝段22在長度上的全部,但並不延伸至汽段24。由於冷凝段22是汽態工作液冷凝為液態工作液的地方,因此,這個分隔件28延伸至該冷凝段22在長度上的全部,就代表液彈管29形成於該冷凝段22的全部,由於液彈管29是較迴流管21口徑更小的管道,因此可以達到讓液態作動液形成液彈的效果,可以使得液態作動液在沒有毛細力的情況下仍可藉由迴流管21內部的壓力差來推動液彈,順利回流至該蒸發腔11內,而被該毛細材14所吸附。In this embodiment, in addition to the liquid section 26, the partition member 28 extends to the condensation section 22 and extends to the entire length of the condensation section 22, but does not extend to the vapor section 24. Since the condensing section 22 is a place where the vaporous working fluid condenses into a liquid working fluid, the partition 28 extends to the entire length of the condensing section 22, which represents the entirety of the liquid bomb tube 29 formed in the condensing section 22 Since the liquid bomb tube 29 is a pipe with a smaller diameter than the return tube 21, it can achieve the effect of forming a liquid bomb from the liquid working fluid, which can make the liquid working fluid pass through the interior of the return tube 21 without capillary force. The pressure difference pushes the liquid bomb, which smoothly flows back into the evaporation chamber 11 and is absorbed by the capillary material 14.
於本實施例中,該汽段24的管徑係與該液段26的管徑相同。此外,各該液彈管29的管徑小於該迴流管21的汽段24的管徑。這可以明確的定義出液彈管29口徑相較於迴流管21的大小關係,此同樣可以理解液彈管29口徑較小而易於形成液彈的效果。In this embodiment, the pipe diameter of the steam section 24 is the same as the pipe diameter of the liquid section 26. In addition, the diameter of each liquid bomb tube 29 is smaller than the diameter of the vapor section 24 of the return tube 21. This can clearly define the size relationship between the diameter of the liquid bomb tube 29 compared to the return tube 21, and it can also be understood that the effect of the small diameter of the liquid bomb tube 29 is easy to form a liquid bomb.
須補充的一點是,如第4圖所示,分隔件28’為板體時,其斷面形狀不一定是直線狀,也可以是弧狀。此外,如第5圖所示,分隔件28’’的數量不一定是一個,也可以是三個分隔件28’’,而將該迴流管21’’分隔為三個液彈管29’’。又,如第6圖所示,分隔件28’’’也可以不是板狀,而是如第6圖所示的在斷面上呈現實心柱體鏤空成管體後的管壁部分。It should be added that, as shown in Fig. 4, when the partition member 28 'is a plate, its cross-sectional shape may not necessarily be linear, but may be arc-shaped. In addition, as shown in FIG. 5, the number of the partition members 28 ″ is not necessarily one, but may be three partition members 28 ″, and the return pipe 21 ″ is divided into three liquid bomb tubes 29 ″. . Further, as shown in FIG. 6, the partition 28 '' 'may not be plate-shaped, but may be a tube wall portion after hollowed out into a pipe body as shown in FIG. 6 in a cross section.
以上說明了本第一實施例的架構,接下來說明本第一實施例的使用狀態。The structure of the first embodiment has been described above, and the use state of the first embodiment is described next.
請參閱第1圖及第2圖,在使用前,先將蒸發腔11貼置於一待散熱物(例如電腦的中央處理單元CPU,圖中未示)上,並將在該迴流管21的冷凝段22設置一散熱單元100,該散熱單元100於本實施例中係由複數鰭片所組成。Please refer to FIG. 1 and FIG. 2. Before use, place the evaporation chamber 11 on a heat-dissipating object (such as a computer's central processing unit CPU, not shown), and place it on the return pipe 21. The condensing section 22 is provided with a heat dissipation unit 100. In this embodiment, the heat dissipation unit 100 is composed of a plurality of fins.
使用時,該待散熱物的熱能會傳遞至該蒸發腔11,該蒸發腔11內部被該毛細材14所吸附的作動液即會蒸發為汽態作動液,而散佈在蒸汽空間16內,這複數個支室162可以有助於提供足夠的空間來讓汽態作動液散佈,並流向該共室161,再進入該迴流管21的汽段24,直到到達該冷凝段22。藉由冷凝段22所設置的散熱單元100讓熱能由空氣帶走的效果,該冷凝段22內部的溫度即較該蒸發腔11的溫度低,這會使得流到該冷凝段22的汽態作動液因為冷卻而凝結成水滴狀的液態作動液,並附著於該冷凝段22內的各個液彈管29管壁。隨著冷凝的液態作動液愈來愈多,水滴狀的液態作動液即愈來愈大,終於會形成佔滿液彈管29截面的液彈311。藉由各個液彈管29的口徑小於迴流管21,可以達到讓液態作動液形成液彈的效果。再加上汽態作動液不斷的由汽段24進入至冷凝段22,自然而然形成一種壓力差而把液彈311由該冷凝段22往液管推,最後即流至蒸發腔11內而再度被該毛細材14所吸附。如此循環作用,即可不斷的將該待散熱物的熱能導出,達到良好的散熱效果。In use, the thermal energy of the object to be dissipated will be transferred to the evaporation chamber 11, and the working fluid adsorbed by the capillary material 14 inside the evaporation chamber 11 will evaporate into a vaporous working fluid and be dispersed in the steam space 16. The plurality of branch chambers 162 can help provide enough space for the vapor-phase operating fluid to spread and flow to the common chamber 161 and then enter the vapor section 24 of the return pipe 21 until reaching the condensation section 22. With the effect that the heat energy is taken away by the air through the heat dissipation unit 100 provided in the condensation section 22, the temperature inside the condensation section 22 is lower than the temperature of the evaporation chamber 11, which will cause the vaporous working fluid flowing to the condensation section 22 Due to cooling, the liquid working fluid condenses into a droplet shape and is attached to the wall of each liquid bomb tube 29 in the condensation section 22. As more and more condensed liquid actuating liquids are formed, the liquid actuating liquids in the shape of water droplets become larger and larger, and finally liquid bombs 311 occupying the cross section of the liquid bomb tube 29 are formed. Since the caliber of each liquid bomb tube 29 is smaller than the return tube 21, the effect of making the liquid working fluid into a liquid bomb can be achieved. In addition, the gaseous working fluid continuously enters the condensation section 22 from the steam section 24, and naturally forms a pressure difference, and the liquid bomb 311 is pushed from the condensation section 22 to the liquid pipe, and finally flows into the evaporation chamber 11 and is again The capillary material 14 is adsorbed. In this way, the thermal energy of the object to be dissipated can be continuously extracted, and a good heat dissipation effect can be achieved.
由上可知,本發明在迴流管21的液段26具有內部分隔成為更小口徑的液彈管29,可以達到讓液態作動液形成液彈的效果,可以使得液態作動液在沒有毛細力的情況下仍可藉由迴流管21內部的壓力差來推動液彈,順利回流至該蒸發腔11內。此外,本發明在迴流管21的液段26沒有組裝編織脈管或其他毛細材,相較於習知技術而言,本發明可降低製造成本,並提高良率。It can be known from the above that the liquid section 26 of the return pipe 21 has a liquid bomb tube 29 which is internally partitioned into a smaller caliber, which can achieve the effect of forming a liquid bomb from a liquid working fluid, and can make the liquid working fluid without capillary forces. The liquid bomb can still be pushed back by the pressure difference inside the return pipe 21 to smoothly return to the evaporation chamber 11. In addition, the present invention does not assemble braided vessels or other capillary materials in the liquid section 26 of the return tube 21. Compared with the conventional technology, the present invention can reduce the manufacturing cost and improve the yield.
如第7圖所示,本發明第二較佳實施例所提供之一種具有液彈管的迴路熱管40,主要概同於前揭第一實施例,不同之處在於:As shown in FIG. 7, a loop heat pipe 40 with a liquid bomb tube provided by the second preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:
該毛細材44與該殼體42之間更形成一儲水空間47,該儲水空間47與該迴流管的液端相連通,且該儲水空間47與該蒸汽空間46不相通。這個儲水空間47可以用來調節作動液的水量,此設計乃是由於傳統迴路熱管本身需要有液段來讓液態作動液回流,但若是蒸發腔內的作動液有大部分都位於迴流管的汽段、冷凝段以及液段內而還沒有回流回來,此時會造成蒸發腔內的水量太少而可能無法有效工作,又稱為乾燒狀態。因此,這個儲水空間47可以提供調節作動液水量的效果,使得蒸發腔41內的作動液49得以保持在一定的量,避免乾燒的問題。A water storage space 47 is formed between the capillary material 44 and the casing 42. The water storage space 47 is in communication with the liquid end of the return pipe, and the water storage space 47 is not in communication with the steam space 46. This water storage space 47 can be used to adjust the amount of water in the working fluid. This design is because the traditional loop heat pipe itself needs a liquid section to return the liquid working fluid, but if the working fluid in the evaporation chamber is mostly located in the return pipe, The steam section, the condensation section and the liquid section have not returned yet. At this time, the amount of water in the evaporation chamber may be too small to work effectively, which is also called dry burning state. Therefore, this water storage space 47 can provide the effect of adjusting the amount of water in the working fluid, so that the working fluid 49 in the evaporation chamber 41 can be maintained at a certain amount, thereby avoiding the problem of dry burning.
此外,於本第二實施例中,該分隔件58係不延伸至該冷凝段52中。這樣雖然會使得液態作動液在冷凝段52中無法直接進入各個液彈管59,但仍然在水量到達一定程度之後就會進入至液管而分別進入到各個液彈管59中。可以理解的是,這樣的結構其液彈形成的效果將略差於前述第一實施例的效果,但藉由該液段56的液彈管59,仍然可以達到讓液態作動液形成液彈的效果,而更容易回流至蒸發腔41。In addition, in the second embodiment, the partition 58 does not extend into the condensation section 52. In this way, although the liquid operating liquid cannot directly enter each liquid bomb tube 59 in the condensation section 52, it still enters the liquid tube and enters each liquid bomb tube 59 after the amount of water reaches a certain level. It can be understood that the liquid bomb formation effect of this structure will be slightly inferior to that of the first embodiment described above, but the liquid bomb tube 59 of the liquid section 56 can still achieve the liquid bomb formation Effect, and easier to return to the evaporation chamber 41.
由本第二實施例可以理解的是,若是該分隔件58僅由該液段56延伸至該冷凝段52在長度上的一半,那麼,其形成的液彈管59當然就延伸至該冷凝段52在長度上的一半,則此種結構形成液彈的效果將優於本第二實施例的上述架構,但卻又劣於前述第一實施例的架構了。It can be understood from this second embodiment that if the partition 58 extends only from the liquid section 56 to half of the condensation section 52 in length, then the liquid bomb tube 59 formed by it of course extends to the condensation section 52 In half the length, the effect of this structure in forming a liquid bomb will be better than the above-mentioned structure of the second embodiment, but inferior to the structure of the aforementioned first embodiment.
本第二實施例的其餘結構及所能達成的功效均概同於前揭第一實施例,容不再予贅述。The rest of the structure and the effects that can be achieved in this second embodiment are the same as those in the first embodiment, and will not be described again.
如第8圖所示,本發明第三較佳實施例所提供之一種具有液彈管的迴路熱管60,主要概同於前揭第一實施例,不同之處在於:As shown in FIG. 8, a loop heat pipe 60 with a liquid bomb tube provided by the third preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:
該分隔件68不僅延伸至該冷凝段62,還延伸至該汽段64的汽端614。The partition 68 extends not only to the condensation section 62 but also to the steam end 614 of the steam section 64.
此種架構將使得汽態作動液在通過汽段64時,就直接進入至小口徑的液彈管69,但由於還沒有到達冷凝段62,因此即使有少量的汽態作動液凝結為小水滴,但其水量也是很少,不足以形成液彈,換言之,此種架構並不會影響整體工作效率,不過,卻由於整個迴流管61內部都是液彈管的架構,因此可以直接取用整條管來組裝,因此不需另外製造沒有分隔件的部分,也不需如前揭第一實施例中需要確定分隔件68是否正確延伸至冷凝段62的位置,因此本第三實施例較第一實施例而言更節省製造成本。This structure will allow the vapor-phase working fluid to directly enter the small-diameter liquid bomb tube 69 when passing through the vapor section 64, but since it has not yet reached the condensation section 62, even a small amount of vapor-phase working fluid will condense into small water droplets. However, the amount of water is very small, which is not enough to form a liquid bomb. In other words, this structure does not affect the overall work efficiency. However, because the entire return tube 61 is a liquid bomb tube structure, it can be used directly. The tube is assembled without the need to separately manufacture the part without the partition, and it is not necessary to determine whether the partition 68 has been correctly extended to the position of the condensation section 62 as in the first embodiment. Therefore, this third embodiment is In one embodiment, the manufacturing cost is further saved.
本第三實施例的其餘結構及所能達成的功效均概同於前揭第一實施例,容不再予贅述。The rest of the structure and the effects that can be achieved in the third embodiment are the same as those in the first embodiment, and will not be described again.
如第9圖所示,本發明第四較佳實施例所提供之一種具有液彈管的迴路熱管70,主要概同於前揭第一實施例,不同之處在於:As shown in FIG. 9, a loop heat pipe 70 with a liquid bomb tube provided by the fourth preferred embodiment of the present invention is mainly similar to the first embodiment disclosed above, except that:
該迴流管71具有二管體71a,71b,一管體71b作為該液段76及該冷凝段72,另一管體71a則作為汽段74,該汽段74的管體口徑小於該液段76及該冷凝段72的管體口徑,該液段76與該冷凝段72的管體71b係套接於該汽段74的管體71a外部的局部來相連,而使內部空間相連通。此種結構主要是說明由二管體71a,71b連接形成該迴流管71的連接關係,而可以進一步理解的是,作為該液段76及該冷凝段72的管體71b可以在內部設置分隔件,而作為該汽段74的管體71a則在內部不設置分隔件。The return pipe 71 has two pipe bodies 71a, 71b. One pipe body 71b serves as the liquid section 76 and the condensation section 72, and the other pipe body 71a serves as the steam section 74. The pipe body diameter of the steam section 74 is smaller than the liquid section. 76 and the diameter of the tube body of the condensation section 72. The liquid section 76 and the tube body 71b of the condensation section 72 are connected to a part of the outer portion of the tube body 71a of the steam section 74 to connect the internal space. This structure mainly explains the connection relationship of the return pipe 71 formed by the connection of the two pipe bodies 71a and 71b, but it can be further understood that the pipe body 71b as the liquid section 76 and the condensation section 72 can be provided with a partition inside The tube body 71a as the steam section 74 is not provided with a partition.
前述架構可以達到使用兩種不同的管體相連接來形成該迴流管71的效果。The aforementioned structure can achieve the effect of using two different pipe bodies connected to form the return pipe 71.
本第四實施例的其餘結構及所能達成的功效均概同於前揭第一實施例,容不再予贅述。The rest of the structure and the effects that can be achieved in the fourth embodiment are the same as those in the first embodiment, and will not be described again.
如第10圖所示,本發明第五較佳實施例所提供之一種具有液彈管的迴路熱管80,主要概同於前揭第四實施例,不同之處在於:As shown in FIG. 10, a loop heat pipe 80 having a liquid bomb tube provided by the fifth preferred embodiment of the present invention is mainly similar to the fourth embodiment disclosed previously, except that:
該迴流管81具有二管體81a,81b,一管體81b作為該液段86及該冷凝段82,另一管體81a作為該汽段84,該汽段84的管體81a係套接於另一管體81b外部的局部來相連接,而使內部空間相連通。由於該汽段84的管體81a口徑小於另一管體81b的口徑,因此實際實施時,是先對該汽段84的管體81a末段進行擴管的動作來使其口徑擴大後,再將之套接連接於另一管體81b。The return pipe 81 has two pipe bodies 81a, 81b. One pipe body 81b serves as the liquid section 86 and the condensation section 82, and the other pipe body 81a serves as the steam section 84. The pipe body 81a of the steam section 84 is sleeved on The outer part of the other tube body 81b is connected to each other, and the internal space is communicated. Since the caliber of the pipe body 81a of the steam section 84 is smaller than the caliber of the other pipe body 81b, in actual implementation, the pipe section 81a of the steam section 84 is first expanded to expand the caliber, and then It is socketed and connected to the other pipe body 81b.
前述結構可以在該汽段84的管體81a口徑小於另一管體81b的情況下,仍能以小口徑管體來套接大口徑管體。In the foregoing structure, when the diameter of the pipe body 81a of the steam section 84 is smaller than that of the other pipe body 81b, the small-diameter pipe body can still be used to socket the large-diameter pipe body.
本第五實施例的其餘結構及所能達成的功效均概同於前揭第四實施例,容不再予贅述。The rest of the structure and the effects that can be achieved in the fifth embodiment are the same as those in the fourth embodiment, and will not be described again.
