The patent application (Publication Number: US20240034122A1) describes a valve set integrated module designed for use in a thermal management system. The module includes a body with internal flow channels and interfaces to connect with an external heat exchange assembly. It features two electric valves that can switch between blocked/unblocked and throttled positions, with one valve connecting the interior condenser outlet to the exterior heat exchanger inlet, and the other valve connecting the exterior heat exchanger outlet to either the interior evaporator inlet or gas-liquid separator inlet.

Furthermore, the module includes a PT low-pressure sensor between the interior evaporator outlet and the gas-liquid separator inlet, an electronic expansion valve connecting the exterior heat exchanger outlet to a plate-type heat exchanger inlet, and a battery pack heat exchanger with an inlet connected to a battery pack heat exchanger inlet and an outlet linked to a gas-liquid separator. The patent also covers a thermal management system incorporating the external heat exchange assembly and the valve set integrated module, as well as a vehicle equipped with this system. Overall, the invention aims to enhance the efficiency and functionality of thermal management systems in various applications.
