The electronic water pump is a key component of the automotive thermal management system. The electronic coolant pump uses a brushless motor to drive the impeller to rotate, which increases the liquid pressure and drives water, coolant and other liquids to circulate, thereby dissipating heat from the coolant. Electronic circulation pumps are mainly used in vehicle preheating systems, automotive engine cooling cycles, hydrogen fuel cell thermal management systems, new energy vehicle drive systems, and electric vehicle battery cooling systems. They are key components of automotive thermal management systems.
As the penetration rate of new energy vehicles increases, it is a general trend for electric water pumps to replace mechanical water pumps. The water pumps in automobile thermal management systems can be divided into mechanical water pumps and electric water pumps. Compared with traditional mechanical water pumps, electronic water pumps have the advantages of compact structure, easy installation, flexible control, reliable performance, low power consumption, and high efficiency. Since new energy vehicles use battery power as driving energy, batteries are more sensitive to temperature under the current technical level. 20-35°C is the efficient operating temperature range of power batteries. Too low temperature (<0°C) will lead to poor battery charge and discharge power performance. decline, shortening the cruising range; excessive temperature (>45℃) will cause the risk of battery thermal runaway, threatening the safety of the entire vehicle. In addition, hybrid vehicles combine the characteristics of fuel vehicles and pure electric vehicles, and their thermal management requirements are more complex than those of pure electric vehicles. Therefore, the characteristics of electronic water pumps such as energy saving, emission reduction, high efficiency, environmental protection, and intelligent cooling determine that they are more suitable for new energy vehicles than mechanical water pumps.
