As a key component of the automotive thermal management system, the electronic water pump plays an important role in the intelligent temperature control of the automotive subsystem, ensuring the safe and reliable operation of the subsystem, and reducing energy consumption. The electronic water pump comprises a water pump casing, and the water pump casing is provided with a channel structure, and attention should be paid to the application of its structure, and the channel structure forms a parallel coolant flow channel with the cooling channel integrated on the motor unit housing; During use, the electronic water pump is forced to cool through the coolant flow channel, and the electronic water pump uses air flow to dissipate heat.
At this stage, there are still many problems to be solved in automobile water pump technology. Aside from the technology itself, as a key part of the thermal management system of the automobile, its heat dissipation and cooling must produce certain environmental problems, and at this stage, under the principle of emphasizing environmental protection and saving production, we should pay attention to the exhaust pollutants and their costs in production, and pay attention to exploring the sustainable development path of electronic water pump technology. As far as the technology itself is concerned, the ambient temperature used by the pump is -40~120 °C, and the three-way catalysis, exhaust pipeline and engine should be avoided as much as possible during the use of the technology to ensure that the ambient temperature meets the requirements. The pump should not run dry, it can run dry for up to 30s. Dry running creates noise and increases wear and tear at the same time.
To avoid dry running, the pump outlet should be vertically up or on the upper side of the impeller. A variety of factors, such as the load at which the motivation works before the flameout is a few important aspects that hinder the application of electronic water pump technology. As far as the market is concerned, with the rapid and sustainable development of China's national economy, the demand for automotive electronic water pump technology in the market is increasing. Through reasonable analysis of economy, sales channels and other aspects, formulate the development plan of electronic water pump, expand the way and channel of application of automotive electronic water pump technology, optimize electronic water pump technology, and help the development of automobile economy.
