In this embodiment, the liquid inlet and the liquid return port are respectively used for connecting corresponding interfaces of a system to be cooled, and the system to be cooled may be a storage battery energy storage system or the like.
In this embodiment, the controller is connected to the coolant temperature sensor 100, the first valve 200, and the second valve 300, respectively, and the controller is configured to control the opening and closing of the first valve 200 and the second valve 300 according to the measurement values of the coolant temperature sensor.
