The invention discloses a battery liquid cooling system with deformation detection and fire extinguishing functions. The battery liquid cooling system comprises a battery module shell, battery cells, cooling plates, an outer circulation assembly and an alarm module. A plurality of battery cells are fixed in the battery module shell, the cooling plates are arranged on the two sides of the battery cells, cooling pipelines are arranged in the cooling plates, and a plurality of mounting grooves are formed in the cooling plates. The cooling pipeline is disconnected at the mounting groove and connected through a hose, and a cutting device is arranged in the mounting groove and used for cutting off the hose. The cooling plate can dissipate heat through two heat dissipation routes of the vehicle shell and the heat dissipation plate, energy is saved, a device is cut off, on one hand, fire combustion after battery cell deformation can be prevented, on the other hand, a driver can be reminded that the battery is deformed, stopping inspection is conducted as soon as possible, and casualties caused by vehicle fire are avoided; the cutting device is designed to be of a structure capable of being separated from the cooling plate, maintenance cost is reduced, and resources are saved.

    本发明公开了一种带变形检测和灭火功能的电池液冷系统,包括电池模组外壳、电芯,冷却板,外循环组件以及报警模块,电池模组外壳内固定有若干电芯,电芯的两侧设有冷却板,冷却板内设有冷却管路,冷却板上设有若干安装槽,冷却管路在安装槽处断开,并用软管连接,安装槽内设有切断装置,切断装置用于切断软管。冷却板可以通过车外壳以及散热板两个散热路线进行散热,节约能源,切断装置,一方面可以防止电芯变形之后起火燃烧,另一方面可以提醒驾驶员电池已经发生变形,尽快停车检查,避免车辆起火造成人员伤亡,切断装置设计成与冷却板可分离的结构,减少了维护成本,节约资源。
