12V/24V Automotive electronic water pump

Short Description:

Automotive electronic water pump is a water pump driven by an electric motor, used to circulate coolant in the car.
Different from the mechanical water pump of traditional fuel vehicles:
Mechanical water pump: driven by the engine belt, it only rotates when the engine is running
Electronic water pump: driven by electricity, can run as fast as you want, regardless of engine/motor speed
Nowadays, electronic water pumps are basically used in new energy vehicles and hybrid vehicles

12V/24V Automotive electronic water pump Description

1. Heat dissipation/insulation for the battery
During fast charging and high-speed driving, the battery heats up and the water pump circulates coolant to cool down; When winter is too cold, it helps to preheat the battery to make it more durable and have better endurance.
2. Provide heat dissipation for the drive motor and electronic control
The temperature of the motor and controller is very high when they are working, and if not cooled, they will directly overheat, limit power, or even burn out.
3. Cooling high-voltage components such as car chargers and DC/DC converters
During fast charging, these components generate significant heat and must be continuously cooled by a water pump.
4. Participate in the heating/cooling of the car's air conditioning system
Combined with the heat pump system, the waste heat from the battery and motor is sent to the car for heating, improving winter endurance.
5. Adjust speed according to demand, more energy-efficient
Slow down when the temperature is low, and fast up when the temperature is high, which is much more energy-efficient than mechanical water pumps.
