One end of the first housing 1 is connected with the second housing 3 to close the opening 31, so that on one hand, the heating device 4 in the second housing 3 can be protected, and on the other hand, the structural layout of the thermal management system 100 is facilitated, so that the thermal management system 100 is compact in structure, and the controller 5 is connected to the end, far away from the second housing 3, of the first housing 1, so that the first housing 1 is connected with the second housing 3, and also the controller 5 is electrically connected with the compressor 2. The controller 5 is electrically connected with the compressor 2 so that the controller 5 can control the compressor 2, and it should be noted that the compressor 2 can generate high-temperature and high-pressure refrigerant, and the compressor 2 can be communicated with the heating device 4, and the heating device 4 is heated by the high-temperature and high-pressure refrigerant.
When only the refrigerating and heating circulation system is required to work, the controller 5 can control the compressor 2 to work, and at the moment, the compressor 2 is connected to the refrigerating and heating circulation system, and no cooling water is injected into the second accommodating cavity 32; when the heating device 4 is required to work simultaneously, the controller 5 can control the compressor 2 to work, the compressor 2 is connected to the refrigerating and heating circulation system, cooling water is injected into the second accommodating cavity 32, the compressor 2 provides high-temperature and high-pressure refrigerant for the heating device 4, and the refrigerant exchanges heat with the cooling water to enable the temperature of the cooling water to rise, so that the temperature of the environment can be raised.
In the whole vehicle heat management, a refrigerating and heating circulation system and a heating system are two important systems, wherein a core component of the refrigerant circulation is a compressor, and a core component of the heating function is a PTC heater. In the related art, two core components are two devices on the whole vehicle, and are controlled by the electric control board of the whole vehicle, so that the total volume and the total weight are large, and the heat dissipation effect of the electric control board of the PTC heater is poor.
