It should be noted here that the outside may be a water pump, an air conditioner, a radiator, etc.

[0075] The purpose of the valve assembly 100 in the present application is to control the flow rate of the inlet and outlet of the thermostat 11. The first liquid guide port 123a can guide the cooling medium from the outside through the radiator or air conditioner into the flow channel of the thermostat, and at the same time, the flow rate of the cooling medium entering the flow channel is controlled by the regulating component; the second liquid guide port 124b can discharge the cooling medium in the flow channel, and the second liquid guide port 124b can be connected to an external water pump to discharge the cooling medium in the flow channel, and the regulating component can control the flow rate of the cooling medium discharged from the flow channel.

[0076] The regulating component provided in the valve assembly 100 is provided on the valve body 12, and the valve assembly 100 is used to adjust the flow of the first liquid guide port 123a and the second liquid guide port 124b, so as to control the flow rate of the cooling medium entering and exiting the temperature control device, so as to achieve the control of the heat dissipation efficiency or temperature of different areas in the temperature control device.
