Embodiment Construction

[0022] Such as Figure 1~Figure 10 As shown, an integrated battery case for uniform cooling of batteries includes a case 1, in which there are more than two vertical liquid cooling plates 3 arranged in parallel, and adjacent liquid cooling plates 3 are provided with There is a battery cell 4, and liquid cooling plates 3 are provided with liquid flow channels running through both ends of the liquid cooling plate 3 in the length direction. Each liquid cooling plate 3 has a set of liquid flow channels, and a set of liquid flow channels includes more than two, distributed up and down. Moreover, the channels arranged in parallel allow the cooling medium to enter different liquid flow channels on both sides of the liquid cooling plate 3 at the same time.

[0023] The box body 1 includes a bottom plate 15 and front side beams 11, left side beams 12, rear side beams 13, and right side beams 14 surrounding the bottom plate 15. The liquid cooling plate 3 and the left side beams 12, righ...

Abstract

The invention provides an integrated battery box body capable of uniformly cooling battery cells. The technical problems that the temperature difference of the battery cells on two sides of the existing integrated battery box is large, and the heat dissipation effect is not ideal are solved. The integrated battery box body capable of uniformly cooling battery cells comprises a box body, two or more parallel and vertical liquid cooling plates are arranged in the box body, the battery cells are arranged between the adjacent liquid cooling plates, and liquid flowing channels penetrating through the two ends of the liquid cooling plates in the length direction are arranged in the liquid cooling plates. A group of liquid flowing channels are arranged in each liquid cooling plate, each group of liquid flowing channels comprises more than two channels which are distributed up and down and arranged in parallel, and cooling media enter different liquid flowing channels at the two sides of the liquid cooling plates at the same time. Each liquid cooling plate is provided with more than two liquid flowing channels, cooling media enter different liquid flowing channels at the same time from the two sides of the liquid cooling plates, cold and hot flow is achieved, the cold and hot heat exchange effect can be achieved, and the temperature uniformity of the liquid media is guaranteed.

Description

technical field [0001] The invention relates to a battery case of an electric vehicle, in particular to an integrated battery case for uniformly cooling electric cores. Background technique [0002] There is a new type of integrated battery box, as disclosed in the Chinese invention patent application with the application number CN202010558272.9. There are multiple liquid-cooled plates arranged in parallel in the box, and the battery cells are arranged between adjacent liquid-cooled plates. To form a sandwich structure, double-sided cooling effect is better, but the cooling medium in the liquid cold plate flows in one side, that is, flows from one side of the box to the other side of the box, because the cooling medium absorbs heat during the flow process , resulting in different temperatures of the cooling medium on both sides of the box, a large difference in cooling effect, and a large temperature difference in the battery core, that is, the heat dissipation effect is not...
