With the global emphasis on environmental protection and sustainable development, new energy vehicles (such as electric vehicles and hybrid vehicles) are rapidly becoming the mainstream of the automotive industry. As one of the core components of the thermal management system of new energy vehicles, the water pump of new energy vehicles plays a vital role in ensuring the efficient and safe operation of vehicles. This article will explore in depth the working principle, characteristics, application and future development trend of the water pump of new energy vehicles.
The role of the electronic water pump of new energy vehicles
The water pump of new energy vehicles is mainly used in the thermal management system of the vehicle, responsible for the circulation of coolant to ensure that key components such as batteries, motors, and electronic control systems work at a suitable temperature. Its core functions include:
1.Battery cooling: prevent battery overheating, extend battery life and improve safety.
2.Motor cooling: ensure that the motor operates within the efficient temperature range and improve power performance.
3.Electronic control system cooling: protect the electronic control unit to avoid functional failure due to overheating.
4.Air conditioning system support: In some models, the water pump also participates in the heat exchange of the air conditioning system.
Working principle of new energy vehicle coolant pump
New energy vehicle water pumps usually adopt electronic drive mode, where the motor directly drives the impeller to rotate and pushes the coolant to circulate in the pipeline. Compared with traditional mechanical water pumps, electronic circulation pumps have higher control accuracy and energy efficiency. Its working process is as follows:
Signal reception: The water pump receives instructions from the vehicle control unit (ECU) and adjusts the speed according to demand.
Liquid circulation: The rotation of the impeller generates centrifugal force, which pushes the coolant from the radiator to the components that need to be cooled.
Heat exchange: The coolant absorbs heat and returns to the radiator, and dissipates heat through fans or external air.
Reciprocating: The coolant circulates continuously to ensure the temperature of each component is stable.
