The invention relates to the technical field of electric vehicle heat management, in particular to a direct heat pump type heat management system. Comprising a cooling liquid loop and a refrigerant loop, and the cooling liquid loop comprises a first cooling loop used for heat management of a battery pack, a second cooling loop provided with a plate heat exchanger, a third cooling loop used for heat management of an electric drive assembly and a fourth cooling loop provided with a radiator; the first cooling loop, the second cooling loop, the third cooling loop and the fourth cooling loop are connected through a seven-way valve; the refrigerant loop comprises a first refrigerating loop used for conducting heat management on the passenger compartment, a second refrigerating loop provided with an evaporator and a third refrigerating loop connected with the plate heat exchanger. The direct heat pump type heat management system is simple in structure, heat pump heating can be achieved in the heat pump mode that a refrigerant releases heat in the indoor condenser and absorbs heat in the outdoor heat exchanger under the condition that the external air temperature is low, and the energy-saving effect of an air source heat pump is reflected to the maximum extent.

    本发明涉及电动汽车热管理技术领域,具体地指一种直接式热泵型热管理系统。包括冷却液回路和制冷剂回路,冷却液回路包括用于电池包热管理的第一冷却回路、设有板式换热器的第二冷却回路、用于电驱总成热管理的第三冷却回路以及安装有散热器的第四冷却回路;第一冷却回路、第二冷却回路、第三冷却回路和第四冷却回路通过七通阀进行连接;制冷剂回路包括用于对乘员舱进行热管理的第一制冷回路、设有蒸发器的第二制冷回路以及与板式换热器连接的第三制冷回路。本申请的直接式热泵型热管理系统结构简单,能够在外部气温较低的情况下采用制冷剂在室内冷凝器放热、室外换热器吸热的热泵方式实现热泵采暖,最大程度体现空气源热泵的节能效果。
