1500W Electric Coolant Pump For Cooling Systems Of New Energy Commercial Vehicles
Product Description
The fuel cell coolant circulation system adopts a closed-loop forced circulation method, powered by a high-voltage electronic water pump. The low-conductivity coolant circulates in the loop, carrying away the heat generated during the operation of the fuel cell stack. Through components such as deionizer, radiator, expansion tank, and electronic thermostat, it achieves precise temperature control, insulation protection, and exhaust pressure stabilization, ensuring that the stack always operates within the optimal temperature range.
Product Features
1. High voltage, high power, and large flow rate
2. Precise speed regulation and intelligent control
3. High insulation, corrosion resistance, and leak-free operation
4. High reliability and long lifespan

Electronic Water Pump Structure
1. The water pump structure is a shielded pump structure;
2. The front bearing housing is in contact with the medium, and the front insulating pad insulates the front bearing housing from the housing;
3. To meet the insulation requirements of the rear bearing housing, a new structure is designed to encapsulate the rear bearing housing and isolate it from the housing, satisfying the insulation requirements between the medium and the housing. The rear bearing housing is separate from the housing and is an independent part. The controller is fixed at the rear end, providing heat dissipation for the controller, reducing temperature rise, and improving the controller's service life. The front end contacts the circulating medium, carrying away the controller's heat.
4. The motor shaft has a hollow structure. The medium enters the shielding sleeve through the front bearing housing in the high-pressure area of the volute, and after reaching the rear bearing housing, it enters the bottom of the motor shaft through the cross groove of the rear bearing housing, returning to the water pump inlet through the central hole of the motor shaft, forming a small heat dissipation circulation system.
