600V Electronic cooling water pump for electric bus and truck
Product Description
The high-voltage electronic cooling water pump is the "heart" of the electric vehicle's three electric system, responsible for promoting the circulation of coolant, achieving heat dissipation, insulation, temperature control, ensuring the safety, durability, and stable performance of the battery and motor.
Electronic cooling water heater description
Adopting a brushless DC motor directly powered by the vehicle's high-voltage power battery, the cooling circulation pump achieves precise and adjustable coolant flow/speed through electronic control; Insulation withstand voltage EMC、 The sealing level is much higher than that of low-pressure pumps.
Core components:
Brushless DC motor (permanent magnet rotor+stator winding, electronic commutation without brush wear);
Integrated controller (MCU+pre drive+power management, supporting CAN/CAN FD communication);
Impeller (engineering plastic/aluminum alloy, optimized flow channel);
Magnetic coupling/mechanical seal (zero leakage design);
Temperature/pressure/speed sensors (closed-loop control+fault diagnosis).

Electronic cooling water heater 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.
