Detailed Description
The application is described in further detail below with reference to fig. 1-3.
The embodiment of the application discloses a liquid cooling and air cooling integrated heat dissipation device.
Example 1
A liquid cooling and air cooling integrated heat radiating device comprises a liquid cooling plate 1 and an air cooling assembly. The cooling channel is arranged in the liquid cooling plate 1, and is arranged in a serpentine structure in the liquid cooling plate 1, and the cooling channel is internally provided with cooling liquid, and in the embodiment of the application, the cooling liquid is water. One surface of the liquid cooling plate 1 is contacted with a heat source, a heat radiating surface is arranged on the other surface of the liquid cooling plate 1, and an air cooling assembly is arranged at a position, close to the heat radiating surface, of the liquid cooling plate 1.
The heat generated by the battery pack is transferred to the liquid cooling plate 1, and the heat is transferred to the radiating surface of the liquid cooling plate 1 on the liquid cooling plate 1. When heat is transferred on the liquid cooling plate 1, the cooling liquid in the cooling channel exchanges heat with the heat transferred by the battery pack to cool, and meanwhile, the heat is conveniently and uniformly transferred to the radiating surface of the liquid cooling plate 1 through the fluidity of the cooling liquid. The air cooling assembly radiates heat to the radiating surface of the liquid cooling plate 1, so that the battery pack is radiated through the liquid cooling plate 1.

The overall flow guide pipe 11 is communicated with two ends of the cooling channel, two ends of the local flow guide pipe 12 are communicated with the interior of the cooling channel, and a liquid outlet end of the local flow guide pipe 12 is positioned at an upstream position of the heat source.
The overall draft tube 11 and the cooling passage integrally form a large circulation cooling passage in which the coolant flows, and heat is transferred to the liquid cooling plate 1 by the flowing coolant. The air cooling assembly dissipates heat from the general draft tube 11 to lower the temperature of the coolant and thus the temperature of the battery pack.
The partial flow guide 12 forms a small circulation cooling channel with the cooling channel. The heat generated by the battery pack is uneven, and the local temperature of part of the battery pack is relatively high. Since the liquid outlet end of the partial flow guide tube 12 is located locally upstream, the path of the coolant flowing inside the small circulation cooling channel is short. After the air cooling component dissipates heat of the local guide pipe 12, the cooled cooling liquid can be quickly returned to the heat source position again to dissipate heat of the heat source and cool down.
The large circulation cooling channel is mainly used for radiating and cooling the cooling liquid of the integral liquid cooling plate 1 and controlling the temperatures of the liquid cooling plate 1 and the battery pack. When the local temperature of the battery pack is too high, the small circulation cooling channel is started to assist in rapid heat dissipation, meanwhile, cooling liquid intermittently flows in the small circulation cooling channel, heat aggregation is reduced, meanwhile, the whole temperature rise of the cooling liquid is reduced, and other areas with lower temperature of the battery pack are prevented from being influenced.
In order to reduce the possibility of leakage of the cooling liquid, the whole flow guiding pipe 11 and the partial flow guiding pipe 12 are hermetically welded with the liquid cooling plate 1.
In order to facilitate the flow of the cooling liquid between the large circulation cooling channel and the small circulation cooling channel, pumps are arranged on the overall flow guide pipe 11 and the local flow guide pipe 12, and the flow of the cooling liquid in the large circulation cooling channel and the small circulation cooling channel is accelerated by the pumps, so that the heat dissipation effect is improved.
In order to facilitate the heat dissipation of the cooling liquid in the overall flow guide pipe 11 and the local flow guide pipe 12, the liquid cooling plate 1 is provided with an overall mounting plate 13 and a local mounting plate 14, the overall flow guide pipe 11 is arranged in the overall mounting plate 13, and the local flow guide pipe 12 is arranged in the local mounting plate 14.
To further reduce the likelihood of leakage of the coolant, the pump is mounted inside the overall and partial mounting plates 13, 14 and is integrally formed with the overall and partial mounting plates 13, 14.
The air cooling assembly comprises a fan 2, the fan 2 being mounted on a general mounting plate 13 and a local mounting plate 14. The fan 2 drives the air flow to dissipate heat of the heat dissipation surfaces of the overall flow guide pipe 11, the local flow guide pipe 12 and the liquid cooling plate 1.
The general mounting plate 13 and the partial mounting plate 14 are connected by a supporting heat-conducting plate 15. In the embodiment of the application, the support heat-conducting plates 15 are arranged in 匚 shapes, the mutually parallel plate surfaces of the support heat-conducting plates 15 are parallel to the liquid cooling plate 1, the plate surfaces close to the liquid cooling plate 1 are in contact with the liquid cooling plate 1, heat on the liquid cooling plate 1 is partially transferred to the support heat-conducting plates 15, the heat dissipation surfaces are increased through the support heat-conducting plates 15, and the heat dissipation efficiency of the liquid cooling plate 1 is improved on the basis of improving the overall mounting plate 13.
The mounting manner of the local mounting plate 14 and the liquid cooling plate 1 is identical to the mounting manner of the overall mounting plate 13 and the liquid cooling plate 1.
The embodiment 1 of the application provides a liquid cooling and air cooling integrated heat dissipating device, which is implemented by the principle that heat is transferred to a cooling channel inside a liquid cooling plate 1 through the contact of the liquid cooling plate 1 and a heat source. The cooling channel is in a serpentine structure, and is filled with cooling liquid (such as water), and the cooling liquid uniformly transfers heat to the radiating surface of the liquid cooling plate 1 through fluidity. The general draft tube 11 and the local draft tube 12 form a large circulation cooling channel and a small circulation cooling channel, respectively, wherein the large circulation cooling channel is used for overall heat dissipation, and the small circulation cooling channel is used for rapid heat dissipation in a local high temperature area. The pumps are arranged on the overall diversion pipe 11 and the local diversion pipe 12, so that the flow of the cooling liquid is accelerated, and the heat dissipation efficiency is improved. The air cooling assembly (comprising the fan 2) is mounted on the overall mounting plate 13 and the local mounting plate 14, and the heat dissipation surfaces of the overall flow guide 11, the local flow guide 12 and the liquid cooling plate 1 are dissipated by air flow. The supporting heat-conducting plate 15 connects the overall mounting plate 13 and the partial mounting plate 14, increasing the heat-radiating area and improving the heat-radiating efficiency. Through the synergism of liquid cooling and forced air cooling, the device can effectively reduce the temperature of battery package, simultaneously through sealed welding and integrated into one piece design, reduces the possibility that the coolant liquid revealed, ensures radiating effect and device reliability.

Specifically, the air flow driven during the running of the automobile is introduced into the air flow box 31 communicated with the first heat dissipation belt, so that the temperature of the first heat dissipation belt is reduced, the air flow after heat exchange is discharged from the other air flow box 31 communicated with the first heat dissipation belt, and the temperature of the second heat dissipation belt and the inside of the heat dissipation cavity 17 is reduced.
