Water pump assembly structure

Abstract

This utility model relates to a water pump assembly structure, including a water-cooled engine, a coolant tank, an electronic water pump, a first coolant pipe, a second coolant pipe, a third coolant pipe, and an electronic control unit. The water-cooled engine is mounted on a vehicle frame and includes a cylinder head, a cylinder, and a water jacket. The cylinder head connects to the cylinder, and the water jacket is housed within the cylinder head and cylinder, including a water jacket inlet and a water jacket outlet. The coolant tank includes a tank inlet, a tank outlet, and a cooler body. The electronic water pump includes a pump inlet, a pump outlet, and a pump body. The two ends of the first coolant pipe are connected to the water jacket outlet and the tank inlet, respectively; the two ends of the second coolant pipe are connected to the tank outlet and the pump inlet, respectively; and the two ends of the third coolant pipe are connected to the pump outlet and the water jacket inlet, respectively. The electronic control unit is electrically connected to the electronic water pump. Therefore, this utility model replaces the mechanical water pump and thermostat of the existing water-cooled engine with an electronic water pump, which automatically controls the water flow rate of the water-cooling system. The speed of the electronic water pump is also adjusted according to the different heat loads of the water-cooled engine, which will avoid the loss of local power of the water-cooled engine and achieve energy saving of the water-cooled engine.
