The invention discloses a thermal management system, a thermal management control method and a heavy truck commercial vehicle, and the thermal management system is used for the heavy truck commercial vehicle and comprises a first thermal management loop which comprises an engine and a radiator; the second heat management loop comprises a compressor, an evaporator and a condenser; and one side of the plate heat exchanger communicates with the first heat management loop, the other side of the plate heat exchanger communicates with the second heat management loop through a first control valve, and the plate heat exchanger is used for conducting heat exchange on cooling liquid in the first heat management loop and a refrigerant in the second heat management loop when the first control valve is switched on. When the temperature of the engine is too high and cannot meet the heat dissipation requirement, auxiliary heat dissipation can be conducted on the engine through the system by means of the refrigerant, so that the temperature of the engine is effectively controlled, and the heat dissipation performance of the whole vehicle is guaranteed.
本发明公开了一种热管理系统、热管理控制方法和重卡商用车,热管理系统用于重卡商用车,热管理系统包括:第一热管理回路,第一热管理回路包括发动机和散热器;第二热管理回路,第二热管理回路包括压缩机、蒸发器和冷凝器;板式换热器,板式换热器的一侧与第一热管理回路连通,板式换热器的另一侧通过第一控制阀与第二热管理回路连通,板式换热器用于在第一控制阀导通时将第一热管理回路中的冷却液与第二热管理回路中的冷媒进行热交换。当发动机温度过高无法满足散热需求时,通过该系统可以利用冷媒对发动机进行辅助散热,从而有效控制发动机温度,保证整车散热性能。
