Preferably, when each managed component needs to be heated, the corresponding water pump needs to be started, the corresponding control water valve is opened, and the heat dissipation water channel of the managed component is guaranteed to be switched to the water channel at the side of the condenser for circulation.
Preferably, in the vehicle-mounted indirect heat management system, the compressor refrigeration and heat pump systems are adjusted and controlled through the heat management system adjusting unit, the water temperatures in the evaporator and the condenser side cold and hot water exchangers are adjusted, and the heat dissipation and heating effects of the managed parts are adjusted through the flow speed and the flow of each water pump.
