The invention provides a liquid cooling plate and a thermal management system for a new energy vehicle. The liquid cooling plate comprises a liquid inlet and a liquid outlet. The liquid cooling plate defines a plurality of first cooling chamber, a second cooling chamber, and a third cooling chamber. The inlet end of each first cooling chamber is communicated with the liquid inlet, the inlet end of the second cooling chamber is communicated with the outlet ends of at least two first cooling chambers, and the inlet end of the third cooling chamber is communicated with the outlet end of the second cooling chamber. Each cooling chamber in the plurality of first cooling chambers and the second cooling chamber is suitable for cooling each battery module respectively, and the third cooling chamber is suitable for cooling a power module. The thermal management system of the new energy vehicle comprises the liquid cooling plate. The liquid cooling plate provided by the invention has relatively good temperature uniformity, and can meet the thermal management requirements of the battery module and the power module at the same time.

    本发明提供一种液冷板和用于新能源车辆的热管理系统。液冷板包括进液口和出液口。液冷板限定了多个第一冷却腔室、第二冷却腔室以及第三冷却腔室。各个第一冷却腔室的入口端与进液口连通,第二冷却腔室的入口端与至少两个第一冷却腔室的出口端连通,第三冷却腔室的入口端与第二冷却腔室的出口端连通。多个第一冷却腔室和第二冷却腔室中的各个冷却腔室适于分别对各个电池模组进行冷却,第三冷却腔室适于对功率模块进行冷却。新能源车辆的热管理系统包括前述液冷板。根据本发明的液冷板具有较好的均温性,并且能够同时满足电池模组与功率模块的热管理需求。
