What are the functions of an automotive electronic water pump?
01-15,2025
An automotive electronic water pump is mainly used for engine cooling system and air conditioning system. The operation of the electronic water pump is independent of the engine RMP, but is powered by an electric motor, leading to higher efficiency and flexibility. It can adjust the flow of coolant in real time according to actual demand. The specific functions include the following:
Effective cooling:
The electronic water pump ensures effective circulation of coolant between the engine and the radiator, thus maintaining ideal operating temperature of the engine and preventing overheating.
Dynamic control:
By adjusting the flow rate in real time, the electronic water pump can improve cooling efficiency, provide required coolant flow for different driving conditions, and consequently maintain optimal temperature for the engine and the system.
Improve fuel efficiency:
By reducing ineffective power consumption (because it only operates when needed), the electronic water pump can improve fuel economy, especially during driving on urban roads or at low speeds.
Reduce emission:
More precise temperature control helps optimize combustion efficiency, thereby reducing exhaust emissions.
Support multifunctional cooling:
Besides cooling the engine, the electronic water pump can also be used to cool high-voltage components such as electric motor and inverter, especially in hybrid vehicles and electric vehicles. It plays a key role in the general cooling management of vehicles.
Reduce noise:
As the operation of the electronic water pump is relatively quiet, it contributes to driving comfort.
Improvements adopted by vika STO electronic water pump:
1. The control module of vika STO electronic water pump uses integrated IPM chips for control, improving the overall response efficiency by 20%.
2. The stator motor of vika STO electronic water pump is based on a slotless design, featuring high torque, small fluctuations, smooth operation, and 20% noise reduction.
3. The rotor of vika STO electronic water pump is small in volume. The material of the stator shell of the motor has been changed to stainless steel to prevent cracking. A 4-pole magnet structure is used to generate more uniform magnetic force, with a 5% increase in demagnetization resistance ability.
