The invention relates to the technical field of heat management, in particular to a pure electric commercial vehicle integrated heat management system based on an indirect heat pump, which comprises an expansion water tank I, a waste heat loop, a refrigerant loop, a battery pack and a cooling liquid loop, a first expansion water tank, a waste heat loop, a refrigerant loop, a battery pack and a cooling liquid loop are adopted, and when the heating environment temperature is low in winter, a direct type heat pump compressor may not be started. Heat is transmitted through the cooling liquid, heat exchange with the battery pack can be achieved, heat exchange with air in a cab can also be achieved, and control and distribution of the heat can be well achieved. The indirect heat pump can more fully utilize an environmental heat source, more effectively save energy and reduce the operation cost. Therefore, the problem that a traditional heat pump system is difficult to start in winter is solved.

    本发明涉及热管理技术领域,具体涉及一种基于间接式热泵的纯电动商用车集成式热管理系统,包括膨胀水箱一、余热回路、冷媒回路、电池包和冷却液回路;本发明采用膨胀水箱一、余热回路、冷媒回路、电池包和冷却液回路,在冬季制热环境温度较低时,直接式热泵压缩机可能无法启动。通过冷却液传输热量,不仅可以与电池包进行换热,也可以与驾驶室内空气进行换热,可以较好的实现热量的控制与分配。间接式热泵可以更充分利用环境热源,更有效节省能源,降低运行成本。从而解决了传统的热泵系统在冬季启动困难的问题。
