Detailed Description
Technical solutions in embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are only some embodiments of the present application, and not all embodiments. In the present invention, the embodiments and features of the embodiments may be combined with each other without conflict. All other embodiments obtained by a person of ordinary skill in the art without any inventive work based on the embodiments in the present application are within the scope of protection of the present application.
Referring to fig. 1 and fig. 2 together, fig. 1 is a schematic structural diagram of a vehicle-mounted power supply provided in the present application; fig. 2 is a schematic view of the three-dimensional heat sink shown in fig. 1 at an angle. The in-vehicle power supply 100 includes a case 101 and a solid radiator 102. The solid heat sink 102 is attached to the housing 101. The three-dimensional radiator 102 has a heat radiation function, so that heat generated by electronic components inside the vehicle-mounted power supply 100 can be uniformly distributed.
Further, referring to fig. 2 to 4, fig. 2 is a schematic structural view of the three-dimensional heat sink 102 shown in fig. 1 at an angle; FIG. 3 is a schematic view of the heat sink 102 shown in FIG. 1 at another angle; fig. 4 is an exploded view of the structure shown in fig. 3. The three-dimensional heat sink 102 includes a heat radiation bottom plate 21 and a heat radiation side plate 22. The heat radiation side plate 22 is located at the periphery of the heat radiation bottom plate 21. The heat sink base 21 has a bottom surface 23 and a top surface 24 opposite to each other. The heat sink base 21 is recessed from the bottom surface 23 toward the top surface 24 to form a primary flow channel 231. The main flow passage 231 is a water flow passage through which the cooling liquid flows.
The top surface 24 is used for mounting a heat generating member (not shown in the drawings). The heat generating member is an electronic component that generates heat inside the vehicle-mounted power supply 100. The heat generated by the heat generating member can be transmitted to the heat dissipating bottom plate 21 and the heat dissipating side plate 22. Wherein, the cooling liquid flowing through the main flow channel 231 can take away the heat dissipation bottom plate 21, thereby dissipating heat of the heat generating component.
The heat dissipation side plate 22 includes a first side plate 221, a second side plate 222, and a third side plate 223. The first side plate 221, the second side plate 222, the third side plate 223 and the heat sink base plate 21 are integrally formed. The first side plate 221 is connected to the edge of the heat sink base plate 21. The second side plate 222 is disposed on a side of the first side plate 221 away from the heat dissipation base plate 21. The third side plate 223 is connected between the first side plate 221 and the second side plate 222. The first side plate 221, the second side plate 222 and the third side plate 223 together enclose a side flow passage 232. The side flow passage 232 is another water flow passage through which the cooling liquid flows. The side flow passage 232 is located at the periphery of the heat generating member and communicates with the main flow passage 231. The coolant flowing through the side flow passage 232 can take away the heat of the heat radiating side plate 22, thereby radiating the heat generating member.
The main flow passage 231 and the side flow passage 232 are water flow passages through which the cooling liquid flows. The side runner 232 is communicated with the main runner 231, the main runner 231 is located at the bottom of the heating member, and the side runner 232 is located around the heating member. When the cooling liquid flows through the main flow channel 231, the heat transferred from the heat generating member to the heat dissipating base plate 21 is taken out to the outside, so that the heat dissipation of the heat generating member is realized. When the cooling liquid flows through the side flow passage 232, the heat transferred from the heating member to the heat dissipation side plate 22 is taken out to the outside, so that the heat dissipation of the heating member is realized.
In the embodiment of the present application, the three-dimensional heat sink 102 not only utilizes the heat dissipation bottom plate 21 to dissipate heat of the heating element, but also is beneficial to the heat dissipation side plate 22 to dissipate heat of the heating element, so that the effective heat dissipation area of the three-dimensional heat sink 102 is increased, and the heat dissipation efficiency of the three-dimensional heat sink 102 is improved. In other words, the heat generated by the heating element can be transmitted to the heat dissipation bottom plate 21 from the bottom of the heating element and can also be transmitted to the heat dissipation side plate 22 from the side of the heating element, and the heat dissipation bottom plate 21 and the heat dissipation side plate 22 can both perform the heat dissipation function, so that the heat of multiple surfaces of the heating element can be dissipated, and the heat dissipation effect of the three-dimensional heat sink 102 on the heating element is improved.
The solid heat sink 102 further includes a cover plate 25. The cover plate 25 is located on a side of the heat-dissipating side plate 22 away from the heat-generating member, and the cover plate 25 covers the main flow channel 231 and the side flow channels 232. In other words, the cover plate 25 covers the heat-dissipating side plate 22 and covers the main flow channel 231 and the side flow channels 232, thereby preventing the coolant from leaving outside and protecting the main flow channel 231 and the side flow channels 232.
When the cover plate 25 covers the main flow channel 231 and the side flow channels 232, heat generated by the heating element is transferred to the cooling liquid through the heat dissipation bottom plate 21 and the heat dissipation side plate 22, one part of the heat transferred to the cooling liquid is taken away by the cooling liquid, the other part of the heat is transferred to the cover plate 25, and the heat is dissipated through the cover plate 25, so that the three-dimensional heat sink 102 dissipates the heat generated by the heating element through the cooling liquid and the cover plate 25, and the heat dissipation efficiency of the three-dimensional heat sink 102 is improved.
Further, referring to fig. 4 and 5, fig. 5 is a schematic top view of the three-dimensional heat sink 102 shown in fig. 4 with the cover plate 25 removed. A plurality of spaced apart protruding members 233 are disposed in the side channel 232 to generate water resistance in the side channel 232. The plurality of protrusion members 233 protrude from the heat-radiating side plate 22 toward the side flow passage 232, and the plurality of protrusion members 233 are disposed at intervals.
In the embodiment of the present application, when the cooling liquid flows through the side channel 232, the plurality of protruding pieces 233 in the side channel 232 can generate water resistance, so as to disperse the flow of the cooling liquid, make the temperature distribution of the flow uniform, and thereby improve the heat dissipation efficiency of the three-dimensional heat sink 102.
Further, the projection member 233 is integrally formed with the heat-radiating side plate 22. In the embodiment of the present application, on the one hand, the protruding member 233 is integrally formed with the heat-dissipating side plate 22, so as to prevent the protruding member 233 from being washed away by the flowing coolant to block the water flow passage. On the other hand, the bump member 233 and the heat-dissipating side plate 22 are integrally formed, so that the process time of the bump member 233 is saved, and the production efficiency of the three-dimensional heat sink 102 is improved.
In other embodiments, the protruding members 233 can be detachably mounted to the heat-dissipating side plate 22. The protrusion members 233 may have different sizes, and a user can selectively select the protrusion members 233 having a suitable size according to the shape of the side fluid passages 232, so that the user can adjust the distribution of the water fluid passages according to the different side fluid passages 232.
Further, the bump element 233 includes a first bump 2331 and/or a second bump 2332. The first protrusion 2331 protrudes from the second side plate 222 toward the first side plate 221, and the first protrusion 2331 is spaced apart from the first side plate 221. The second protrusion 2332 protrudes from the first side plate 221 toward the second side plate 222, and the second protrusion 2332 is spaced apart from the second side plate 222.
In the embodiment of the present application, the first protruding block 2331 is spaced apart from the first side plate 221, and the second protruding block 2332 is spaced apart from the second side plate 222, so that the protruding block 233 is spaced apart from the groove wall of the heat dissipation side plate 22, which is disposed opposite to the protruding block 233, thereby preventing the protruding block 233 from blocking the side flow channel 232, ensuring that the cooling liquid can smoothly flow, and ensuring the heat dissipation effect of the three-dimensional heat sink 102.
In one embodiment, the tab member 233 is located only on the second side plate 222. In another embodiment, the tab member 233 is located only on the first side plate 221. In another embodiment, the protruding elements 233 are disposed on the second side plate 222 and the first side plate 221.
In the embodiment of the present application, the bump 233 is located on the second side plate 222 and the first side plate 221 for illustration. As shown in fig. 5, the bump member 233 includes a first bump 2331 and a second bump 2332. The number of the first bumps 2331 and the second bumps 2332 is plural, and the first bumps 2331 and the second bumps 2332 are alternately arranged in a staggered manner.
In the embodiment of the present invention, the number of the first bumps 2331 and the second bumps 2332 is multiple, so that the temperature of the water flow is more uniform, and the heat dissipation effect of the three-dimensional heat sink 102 is more favorable. The first bumps 2331 and the second bumps 2332 are alternately arranged in a staggered manner, so that the bumps 233 can break up water flows on two opposite sides in the side flow passage 232, the water flow breaking effect is better, and the temperature of the water flows is more uniform.
Further, the side runners 232 include a first side runner 2321 and a second side runner 2322 spaced apart from the first side runner 2321. The first side flow passage 2321 and the second side flow passage 2322 are located upstream and downstream of the primary flow passage 231, respectively. That is, the primary flow passage 231 communicates the first side flow passage 2321 with the second side flow passage 2322. The first side flow channel 2321 and the second side flow channel 2322 are located at the periphery of the main flow channel 231.
As shown in fig. 5, the side flow passage 232 is disposed around the main flow passage 231. The primary flow passage 231 is spaced between the first side flow passage 2321 and the second side flow passage 2322. The cooling liquid flows through a part of the side channels 232, then flows through the main channel 231, and the cooling liquid flowing through the main channel 231 flows through another part of the side channels 232.
Further, the three-dimensional radiator 102 includes a water inlet pipe 26 and a water outlet pipe 27. The inlet pipe 26 communicates with the first side flow passage 2321. The water outlet pipe 27 is communicated with the second side flow passage 2322.
In the embodiment of the present application, the cooling liquid flows into the main flow channel 231 after flowing through the first side flow channel 2321 from the water inlet pipe 26, and the cooling liquid in the main flow channel 231 flows into the second side flow channel 2322 and then flows out of the outside through the water outlet pipe 27.
Further, the main flow passage 231 includes at least two first main flow passages 2311 and at least one second main flow passage 2312. The second main flow passage 2312 connects adjacent two first main flow passages 2311. Specifically, the first main flow passage 2311 extends in a straight shape. The second main flow channel 2312 is connected between two adjacent first main flow channels 2311, and the second main flow channel 2312 is bent. In the embodiment of the present application, the second main flow passage 2312 connects two adjacent first main flow passages 2311 to increase an extension path of the main flow passage 231 within an effective area. As shown in fig. 5, any two adjacent first main flow passages 2311 communicate through a second main flow passage 2312. The number of the first main flow passage 2311 and the second main flow passage 2312 is plural.
In the embodiment of the present application, the first main flow channel 2311 is a straight flow channel, and the second main flow channel 2312 is a buffer bending flow channel. When the coolant flowing through one of the first main flow passages 2311 reaches the second main flow passage 2312, it is buffered and changed in flow direction, and flows into the other first main flow passage 2311 in the opposite direction. That is, the flow directions of the cooling liquid in the first main flow passage 2311 of two adjacent main flow passages are opposite. The combination of the first main flow channel 2311 and the second main flow channel 2312 makes the main flow channel 231 be an "S-shaped" flow channel, so that the "S-shaped" main flow channel 231 prolongs the flow path of the cooling liquid, thereby improving the utilization rate of the cooling liquid, and also making the heat dissipation effect of the three-dimensional heat sink 102 better.
In the embodiment of the present application, the main flow channel 231 is divided, so that the cooling liquid flows out of the main flow channel 231 more reasonably, and the heat transferred to the heat dissipation base plate 21 is effectively taken away, so that the heat dissipation member is effectively dissipated by the three-dimensional heat sink 102.
Further, the depth of the first side flow passage 2321 is greater than the depth of the primary flow passage 231. And/or the depth of the second side flow passage 2322 is greater than the depth of the primary flow passage 231. The bottom surface 23 faces the top surface 24 in the depth direction.
In this embodiment, the depth of the first side flow channel 2321 is greater than the depth of the main flow channel 231, so that the side of the heat generating member contacts with the inner surface of the heat dissipating side plate 22 enclosing the first side flow channel 2321, and heat generated by the heat generating member can be transferred to the heat dissipating side plate 22 from the side of the heat generating member, so that the heat dissipating side plate 22 performs a heat dissipating function. Accordingly, the depth of the second side flow channel 2322 is greater than the depth of the main flow channel 231, so that the side of the heat generating member contacts the inner surface of the heat dissipating side plate 22 enclosing the second side flow channel 2322, and heat generated by the heat generating member can be transferred to the heat dissipating side plate 22 from the side of the heat generating member, so that the heat dissipating side plate 22 performs a heat dissipating function.
In one embodiment, only the depth of the first side flow passage 2321 is greater than the depth of the primary flow passage 231. In another embodiment, only the depth of the second side flow passage 2322 is greater than the depth of the primary flow passage 231. In another embodiment, the depth of the first side flow channel 2321 and the depth of the second side flow channel 2322 are both greater than the depth of the primary flow channel 231.
In the embodiment of the present application, the depth of the first side flow channel 2321 and the depth of the second side flow channel 2322 are both greater than the depth of the main flow channel 231.
In the embodiment of the present application, the depths of the first side flow channel 2321 and the second side flow channel 2322 are greater than the depth of the main flow channel 231, so that heat can be transferred from the inner surfaces of the heat dissipation side plate 22 to the heat dissipation side plate 22, the heat dissipation area of the heat dissipation side plate 22 is increased, and the heat dissipation efficiency of the three-dimensional heat sink 102 is increased.
Further, the end of the heat-radiating side plate 22 facing the cover plate 25 is provided with a groove (not shown in the figure). The groove is located on one side of the side channel 232 away from the main channel 231, and the groove and the side channel 232 are arranged at an interval. Sealing rings (not shown) are arranged in the grooves and are used for sealing the radiating side plates 22 and the cover plate 25. Specifically, the sealing ring isolates the inside of the three-dimensional heat sink 102 from the outside, so as to prevent external objects from entering the inside of the three-dimensional heat sink 102, and simultaneously plays roles of dust prevention, water prevention and insect prevention.
