Automotive electric water pump is the refers to the water pump with electric control drive unit used in automobile. It is mainly composed of overcurrent unit, motor unit and electric control unit. Due to the electric control unit, the working state of the water pump can be adjusted at will, such as controlling the start / stop of the water pump, flow control, pressure control, anti dry operation protection, self maintenance and other functions. The working state of the water pump can be controlled through external signals. The power of automotive electric water pumps is relatively small, generally below 1000W, and the motor generally adopts DC brushless motor. 

Automotive electric water pumps are used in new energy vehicles, RVs, and other special vehicles, which often use micro water pumps as water circulation, cooling, or on-board water supply systems

Advantages of automotive electric water pumps:

The characteristics of automotive electric water pumps, such as energy conservation and emission reduction, high efficiency and environmental protection, and intelligent cooling, determine that their replacement of mechanical water pumps is the trend. Precision cooling "is the use of the minimum coolant flow to achieve optimal temperature distribution. The key to the design of a precise cooling system is to select a matching cooling water pump to ensure that the system's heat dissipation capacity can meet the temperature requirements of key areas of the engine at low speeds and high loads. The engine using an electric water pump cooling system can reduce the coolant flow rate by 40% throughout the entire operating speed range. Under the same configuration and cooling requirements, the energy consumption of the electric DC brushless water pump is only 16% of that of the mechanical water pump.

Automotive electric water pump has many advantages, such as compact structure, convenient use, powerful function, long service life, stable performance, low noise, low energy consumption, high efficiency and so on. Therefore, it is deeply favored by people in the industry. With the rapid development of industry, the application field of electric water pump is more and more widely, especially in the field of new energy vehicles. In addition, with the rapid development of science and technology, the application of micro electric water pump will be a new reform in the fields of artificial intelligence, biotechnology and medical industry, which has far-reaching significance for the development of modern science and technology industry.
