Thermal management integrated component, system and vehicle

The utility model discloses a heat management integrated component, a system and a vehicle. The heat management integrated component comprises a frame and a refrigerant module. A refrigerant flow channel is arranged in the refrigerant module; the frame comprises a plate-shaped area and a hollow area, and the area of the plate-shaped area is smaller than or equal to that of the hollow area; the refrigerant module is fixed to the plate-shaped area, and the area of the refrigerant module is smaller than or equal to the area of the plate-shaped area. The frame is further used for being integrated with a substrate, and a cooling liquid flow channel is arranged in the substrate. According to the scheme, the integration cost of the thermal management system can be reduced.
