The invention discloses a battery thermal management system. The system comprises a box body, a pump body and a refrigeration cycle assembly, the refrigeration cycle assembly comprises a compressor, acondenser, a plate heat exchanger and a pressure expansion valve which are connected end to end in series, the plate heat exchanger is used for exchanging heat with a cooling liquid, the pump body iscommunicated with the plate heat exchanger, the pump body is used for inputting the cooling liquid into a battery pack, the compressor is arranged in the box body, and a first buffer part and a second buffer part are arranged between the compressor and the box body in a relatively inclined mode. The pump body and the refrigeration cycle assembly can be matched to cool the battery pack, the firstbuffer part and the second buffer part are arranged in the relatively inclined mode, both the first buffer part and the second buffer part can play a role in buffering, and the first buffer part and the second buffer part can hedge each other to reduce the vibration amplitude of the compressor, so the battery thermal management system can continuously cool the battery pack, and the working stability is good.
本发明公开了一种电池热管理系统,包括箱体、泵体及制冷循环组件,制冷循环组件包括首尾串联的压缩机、冷凝器、板式换热器及压力膨胀阀,板式换热器用于与冷却液换热,泵体与板式换热器连通,泵体用于将冷却液输入电池包,压缩机设于箱体内,压缩机与箱体之间设有第一缓冲件及第二缓冲件,第一缓冲件及第二缓冲件相对倾斜设置。上述电池热管理系统,泵体与制冷循环组件可配合对电池包降温,第一缓冲件与第二缓冲件相对倾斜设置,第一缓冲件与第二缓冲件均可起到缓冲作用,且第一缓冲件与第二缓冲件可对冲,减小压缩机的振动幅度,则上述电池热管理系统可持续提供对电池包的降温,工作的稳定性较好。
