AISIN Inverter Water Pumps are a type of automotive component used in hybrid and electric vehicles to control the flow of coolant through the power inverter, helping to regulate the temperature and improve the overall performance and efficiency of the powertrain. The power inverter is a key component of the hybrid and electric vehicle powertrain, it converts the DC power stored in the battery to AC power used to drive the electric motor. The inverter generates a lot of heat during operation, and the water pump is responsible for circulating coolant through the inverter to dissipate this heat. The coolant flow is precisely controlled by the water pump to ensure that the inverter operates within its optimal temperature range, which can improve efficiency, extend the life of the inverter and maintain peak performance.
