VALVE BLOCK DEVICE, CONTROL METHOD, VEHICLE COOLING SYSTEM AND VEHICLE

This application discloses a valve assembly apparatus, a control method, a vehicle cooling system, and a vehicle, and relates to the field of vehicles, to reduce costs of performing cooling or heating in a vehicle by using a heat pump. The valve assembly apparatus includes a controller, an actuator, a first inlet and outlet set, and a second inlet and outlet set. The first inlet and outlet set includes a first coolant inlet and outlet and a second coolant inlet and outlet. The second inlet and outlet set includes one or more of the following inlets and outlets: a powertrain inlet and outlet, a passenger cabin heating inlet and outlet, and a front end inlet and outlet. An inlet in the inlet and outlet is configured to allow inflow of coolant, and an outlet in the inlet and outlet is configured to allow outflow of coolant. The controller is configured to control, based on a working condition of a vehicle cooling system, the actuator to communicate at least one inlet in the first inlet and outlet set with at least one outlet in the second inlet and outlet set, and communicate at least one outlet in the first inlet and outlet set with at least one inlet in the second inlet and outlet set.
