The utility model provides a battery box with cooling function, which includes a water-cooled plate and four side plates. The water-cooled plate includes a plurality of water-cooled plate units, each of which includes a bottom plate and two water chambers. The inside of the bottom plate is provided with a plurality of flow channels. The two water chambers are respectively fixed at both ends of the bottom plate, and the bottom of the water chamber is connected with all flow channels. The upper part of the water chamber is provided with There are water joints, all water-cooled plate units are fixed side by side to form the water-cooled plate, the four side plates are respectively vertically fixed on four sides of the water-cooled plate, and the sides of any two adjacent side plates are sealed and connected. The beneficial effect of the utility model: it can not only meet the heat dissipation function of the battery module, but also strengthen the structural strength of the bottom surface of the box, improve the bearing capacity, effectively avoid the leakage problem caused by the failure of the water-cooled plate, use the internal space of the box for the heat dissipation of the battery module, reduce the number of parts and the overall weight of the whole battery pack, simple process, and high utilization rate of the box space.

一种带冷却功能电池箱体
本技术涉及电池冷却
,尤其涉及一种带冷却功能电池箱体。
技术介绍
目前市场上主流的电动汽车的电池大多采用液冷方式,通常做法是把水冷板设置在电池包内模组下方。为防止极端工况下(加速、减速、上下坡、转弯等)水冷板失效而发生泄漏,一般不要求水冷板承重,而是在口琴管下方设计支撑结构,这样电池包内模组下方就需要预留较多空间,导致箱体内空间利用率低,由于电动汽车内空间有限,制约电池包内模组的体积,拉低了电池能量密度,提高箱体空间利用率。
技术实现思路
有鉴于此,本技术的实施例提供了一种带冷却功能电池箱体。本技术的实施例提供一种带冷却功能电池箱体,包括水冷板和四个侧板,所述水冷板包括多个水冷板单元,每一所述水冷板单元包括底板和两水室,所述底板内部设有多个流道,两所述水室分别固定于所述底板的两端,且所述水室底部和所有流道连通,所述水室上部设有水接头,所有水冷板单元并排固定形成所述水冷板,四所述侧板分别垂直固定于所述水冷板的四边,任意相邻两所述侧板的侧边密封连接。进一步地,包括至少一个隔板,所述隔板设置于相邻两所述水冷板单元的重合边线上。进一步地,任意相邻两所述侧板的侧边之间设有焊接块,所述焊接块两侧分别焊接一所述侧板。进一步地,所述底板为挤压型材,所述流道为矩形管状流道,多个所述流道并排平行设置。进一步地,所述水室上部设有螺纹孔,所述水接头为管状接头,所述水接头下端设有外螺纹,所述水接头下端螺纹连接所述螺纹孔。本技术的实施例提供的技术方案带 ...
