Description

Technical Field

[0001] The utility model relates to the field of new energy vehicle batteries, in particular to a new energy power end plate battery compartment cooling device. Background Art

[0002] As the energy output unit of new energy electric vehicles, the power battery module is mainly composed of battery packs and structural parts. The structural parts mainly provide the strength and rigidity of the battery module and protect the internal battery pack. The fixed structural parts at both ends of the length direction of the battery module are generally called end plates. Their materials, structural forms and fixing methods play an extremely important role in the performance of the entire battery module. At present, the battery compartment of new energy vehicles generally adds thermal conductive silicone gaskets at the top and bottom of the electrode end of the battery pack, and heat dissipation holes and heat dissipation fans are set on both sides of the battery compartment to dissipate heat. However, since the two ends of the battery pack in the length direction are blocked by the end plates, the above heat dissipation method cannot dissipate heat well at both ends of the battery pack in the length direction, affecting the heat dissipation effect.

[0003] According to the published patent 202321462195.2, a new energy power end plate battery compartment cooling device comprises a battery compartment and a battery pack, a compartment cover is arranged on the top of the battery compartment, a bracket assembly is arranged on the bottom of the inner wall of the battery compartment, two end plates are arranged on the bracket assembly, and the battery pack is arranged between the two end plates, and an air cooling assembly is arranged on the battery compartment, and water cooling assemblies are arranged on the two end plates. The beneficial effects of the utility model are as follows: the interior of the battery compartment can be air-cooled and the end plates can be water-cooled, so that the battery compartment and the end plates both have cooling structures, so that the upper and lower ends, the front and rear ends, and the left and right ends of the battery pack can be effectively dissipated, and the heat dissipation effect of the battery pack is effectively improved. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. Although the battery compartment, compartment cover, battery pack, end plate, bracket assembly, air cooling assembly and water cooling assembly are arranged The use of the components can cool the battery compartment with air and the end plate with water, so that both the battery compartment and the end plate have cooling structures, so that the upper and lower ends, the front and rear ends, and the left and right ends of the battery pack are effectively cooled, effectively improving the heat dissipation effect of the battery pack. The battery compartment of the current new energy vehicle generally adds thermal conductive silicone gaskets on the top and bottom of the battery pack electrode, and heat dissipation holes and heat dissipation fans are set on both sides of the battery compartment to dissipate heat. However, since the two ends of the length direction of the battery pack are blocked by the end plate, the above heat dissipation method cannot dissipate the heat of the two ends of the length direction of the battery pack well, affecting the heat dissipation effect. However, during use, the traditional new energy power end plate battery compartment cooling device uses water cooling to cool the battery. This cooling method, because the water is repeatedly circulated, causes the water temperature to rise with the cycle time, affecting the cooling effect of the battery pack. For this reason, it is necessary to design a new technical solution to solve it. Utility Model Content

This cooling method, due to the repeated circulation of water, causes the water temperature to rise with the circulation time, affecting the technical problem of the cooling effect on the battery pack.
