Referring to fig. 1, 2 and 3, an embodiment of the present invention discloses a fish gathering lamp, which is a simplified model, mainly shows a heat dissipating system and a light source related to the present invention, and omits unimportant matters such as a power supply, an electric wire, a fixing structure, etc. The fish gathering lamp comprises an air inlet piece 1, an air channel piece 2, a heat radiating piece 3 and a light source plate 4, wherein the air inlet piece 1 can be equipment such as a fan which can drive air to enter the air channel piece 2, the air channel piece 2 is a part which can guide wind direction, the air channel piece 2 is provided with an air inlet 21 and a transition port 22, the air inlet 21 is communicated with the transition port 22, the air inlet piece 1 is fixed in the air inlet 21 and is communicated with the air inlet 21, and external air can enter the air channel piece 2 through the air inlet piece 1. In the air duct member 2, due to the effect of the internal structure of the air duct member 2, the air has less pressure loss in the air duct member 2, and the air speed entering the heat dissipation member 3 from the air duct member 2 is high, so that the heat dissipation member 3 can be assisted to dissipate heat rapidly. The heat dissipation piece 3 is communicated with the air duct piece 2, the light source plate 4 is attached to the side part of the heat dissipation piece 3, and when the light source plate 4 operates, heat emitted by the light source plate can be continuously transferred to the side part of the heat dissipation piece 3. The heat dissipation piece 3 is fixed in on the transition port 22, the inside heat dissipation channel 31 that is equipped with of heat dissipation piece 3, the air gets into heat dissipation channel 31 from wind channel piece 2, simultaneously, the heat transfer of light source board 4 is to the heat dissipation channel 31 lateral wall, the bottom of heat dissipation channel 31 is equipped with air-out end 311, finally, the heat of heat dissipation channel 31 lateral wall can be taken away to the air that flows, the heat of light source board 4 can be discharged through air-out end 311, consequently, under the synergism of air inlet piece 1, wind channel piece 2 and heat dissipation piece 3, the heat of light source board 4 can in time obtain discharging, radiating efficiency has been improved. The air inlet 21 is vertically arranged downwards or obliquely arranged downwards, and at the moment, the air inlet end of the air inlet piece 1 is vertically arranged downwards or obliquely arranged downwards, so that splash and rainwater splashed beside the fishing boat are not easy to fall into the air inlet piece 1 or the air inlet 21, and the normal operation of the air inlet piece 1 and the normal heat dissipation of the heat dissipation piece 3 are ensured.
The embodiment of the invention has the following beneficial effects:
the fish gathering lamp provided by the embodiment of the invention is provided with the air inlet piece 1, the air duct piece 2, the heat dissipation piece 3 and the light source plate 4, wherein the air inlet piece 1 blows external air into the heat dissipation piece 3 through the air duct piece 2, the heat dissipation piece 3 is internally provided with the heat dissipation channel 31, the light source plate 4 is attached to the side part of the heat dissipation piece 3, when the fish gathering lamp is used, heat of the light source plate 4 can be transferred into the heat dissipation piece 3, and the air blown into the heat dissipation channel 31 can timely take the heat transferred by the light source plate 4, so that the effect of rapid heat dissipation is achieved. Moreover, the orifice of the air inlet 21 of the air duct member 2 is horizontally arranged or is arranged obliquely downwards, and the air inlet member 1 is vertically arranged downwards or is arranged obliquely downwards according to the air inlet 21, so that splashed water and rainwater are not easy to fall into the air inlet member 1 or the air inlet 21 from above, thereby achieving the waterproof effect and having good waterproof performance.
Specifically, referring to fig. 4, the air duct member 2 further includes a first side 23, the air inlet 21 is disposed on the first side 23, and the air inlet member 1 is mounted in the first side 23 along an angle of the first side 23, so that an inclination angle of the air inlet member 1 is equal to that of the first side 23, and when in use, the first side 23 is vertically disposed or obliquely disposed, so that the air inlet 21 and an air inlet end of the air inlet member 1 can be horizontally disposed or obliquely disposed downward, and water is prevented from dripping into the air inlet member 1 or the air inlet 21. In addition, the first side 23 arranged vertically or obliquely is beneficial to enabling the water drops falling into the first side 23 to be smoothly discharged along the first side 23 under the action of gravity, so that the drainage property and the water resistance are enhanced.
The air duct member 2 further includes a first top surface 24 and a second top surface 25 (see fig. 1), where the first top surface 24 and the second top surface 25 are both disposed on top of the air duct member 2, and the first top surface 24 and the second top surface 25 can provide a sealing effect for the air duct member 2 and also can provide a water blocking effect for the heat dissipation member 3, and more importantly, the first top surface 24 and the second top surface 25 can determine a pressure loss level of the external air after entering the air duct member 2. After the external air enters the air duct member 2, under the condition that the air inlet 21 is inclined, the air can generate collision turbulence on the first top surface 24 and the second top surface 25, and can generate collision turbulence at the intersection of the first top surface 24 and the second top surface 25, the corner of the first top surface 24 and the corner of the second top surface 25, wherein the turbulence influence at the intersection of the first top surface 24 and the second top surface 25 is larger, so that the included angle between the first top surface 24 and the second top surface 25 needs to be specially set.
In use, one end of the first top surface 24 is interconnected with one end of the second top surface 25, and the first top surface 24 is at an angle in the range of 30 ° -250 ° to the plane of the second top surface 25. When the plane included angle between the first top surface 24 and the second top surface 25 is smaller than 30 degrees, the junction between the first top surface 24 and the second top surface 25 is very narrow, after air enters the junction, the air is difficult to transfer from the junction to the transition port 22, so that the ventilation efficiency is affected, and when the plane included angle between the first top surface 24 and the second top surface 25 is larger than 250 degrees, the junction formed by the first top surface 24 and the side part of the air duct member 2, the junction formed by the second top surface 25 and the side part of the air duct member 2 is very narrow, so that the air is not beneficial to enter the transition port 22 from the junction, the ventilation efficiency is also affected, and the heat exchange efficiency is further affected.
When the plane included angle between the first top surface 24 and the second top surface 25 is smaller than 180 degrees, the first top surface 24 and the second top surface 25 form inclined planes with the outer ends inclined downwards and the inner ends protruding upwards, at the moment, the outer walls of the first top surface 24 and the second top surface 25 can play roles in retaining water and facilitating drainage, small triangles exist at the junction of the first top surface 24 and the second top surface 25, and outside air can collide at the junction, so that although certain local pressure loss can be generated, the travel of the air in the air duct piece 2 is shortened, and the travel pressure loss can be reduced. When the plane included angle between the first top surface 24 and the second top surface 25 is equal to 180 degrees, the first top surface 24 and the second top surface 25 are positioned on the same plane, and a small triangle does not exist at the joint of the first top surface 24 and the second top surface 25, so that the external air cannot collide at the joint, the local pressure loss is lower, and the stroke pressure loss is correspondingly increased. When the included angle between the planes of the first top surface 24 and the second top surface 25 is larger than 180 degrees, the first top surface 24 and the second top surface 25 form inclined planes with the outer ends protruding upwards and the inner ends inclined downwards, at this time, the first top surface 24 and the second top surface 25 are arranged obliquely, water drainage can be facilitated, in addition, external air can be divided into two strands after passing through the intersection of the first top surface 24 and the second top surface 25, and the two strands of air can respectively act on two parts of the heat dissipation part 3.
As a preferred solution, the plane included angle of the first top surface 24 and the second top surface 25 is 90 °, and the first top surface 24 and the second top surface 25 which are perpendicular to each other are capable of balancing the increase of local pressure loss and the increase of stroke pressure loss, as shown in fig. 5 and 11, which are numerical simulation diagrams of the heat dissipation result of the heat dissipation element 3 when the plane included angle of the first top surface 24 and the second top surface 25 is 90 °, which illustrate the temperature distribution of each area of the heat dissipation element 3 when the plane included angle of the first top surface 24 and the second top surface 25 is 90 °, wherein the temperature of most area of the heat dissipation element 3 is lower, 88 ℃, and the local temperature of the bottom is highest, 90 ℃, at a lower level.
As a preferable scheme, the included angle between the planes of the first top surface 24 and the second top surface 25 is 180 degrees, the first top surface 24 and the second top surface 25 are positioned on the same plane, a small triangle does not exist at the joint of the first top surface 24 and the second top surface 25, and the local pressure loss is low. Fig. 6 and 12 are numerical simulation diagrams of the heat dissipation result of the heat dissipation element 3 when the plane included angle between the first top surface 24 and the second top surface 25 is 180 °, in which the temperature of most regions of the heat dissipation element 3 is lower, 82 ℃, and the local temperature of one end of the bottom of the heat dissipation element 3 is highest, 89 ℃, and still at a lower level.
After the external air enters the air duct member 2 and collides with the inner walls of the first top surface 24 and the second top surface 25, the external air turns to flow toward the transition port 22 and flows from the transition port 22 into the heat dissipation passage 31. The heat dissipation element 3 is provided with a mounting surface 32, the light source plate 4 is attached to the mounting surface 32, the mounting surface 32 is parallel to the flow direction of the heat dissipation channel 31, so that the angle at which air enters the transition opening 22 from the first top surface 24 and the second top surface 25 is greatly related to the inclination degree of the first side surface 23, which is the plane of the air inlet 21, and the inclination degree of the first side surface 23 is defined by the included angle between the plane of the mounting surface 32 and the plane of the first side surface 23, and in a numerical simulation experiment, the included angle between the plane of the mounting surface 32 and the plane of the first side surface 23 is preferably 30-150 degrees. When the included angle between the plane of the mounting surface 32 and the plane of the first side surface 23 is smaller than 30 degrees, the air inlet end of the air inlet piece 1 is too close to the heat dissipation piece 3 due to the fact that the first side surface 23 is too inclined, the heat dissipation piece 3 blocks the air inlet piece 1, the air inlet quantity is influenced, and therefore heat dissipation efficiency is influenced, and when the included angle between the plane of the mounting surface 32 and the plane of the first side surface 23 is larger than 150 degrees, the space of the air channel piece 2 is too small, and the problem of overlarge air inlet resistance is easily caused, so that heat dissipation efficiency is influenced.

When the radius of the air channel rounding 262 is less than 5cm, the air is insufficient in the transition of the air channel rounding 262, more severe turbulence is easily caused, and the energy of the air is consumed, so that the heat dissipation efficiency is influenced, and when the radius of the air channel rounding 262 is greater than 50cm, the transition range of the air channel rounding 262 is overlarge, so that the space in the air channel piece 2 is compressed, and finally the air quantity is reduced or the wind resistance is increased, so that the heat dissipation efficiency is influenced.
