Abstract

The invention provides an electronic water pump and a new energy automobile with the electronic water pump. Through assembling of an inserting needle assembly, a sealing pad and a rear cover, assembling of an electrical connector can be finished in a simple manner, sealing is conducted through the sealing pad and the rear cover, the sealing performance of the connector is improved, and the problems that assembling of the electrical connector is not easy, and water leakage is likely to happen are solved. Meanwhile, through a heat dissipation partition plate arranged in a machine shell and heatdissipation ribs arranged on the outer surface of the circumference of the machine shell, the problem that electronic water pumps are not good in heat dissipation is effectively solved, wherein the problem commonly exists in the industry. The electronic water pump has the advantages that the waterproof effect is good, the heat dissipation performance is good, the service life of the product is long, the production efficiency is high, installation is firm, the assembling technology is simple, and cost is low.

Description

technical field [0001] The invention relates to a thermal management system of a new energy vehicle, in particular to an electronic water pump and a new energy vehicle equipped with the electronic water pump. Background technique [0002] With the country's higher and higher requirements for environmental protection, electric vehicles are developing at a rapid pace. The batteries, motors, motor controllers, chargers and other components of electric vehicles will generate a lot of heat during the working process. The accumulation of heat will cause the relevant components to fail or even spontaneously ignite. Therefore, the electric vehicle must design a cooling system for the relevant components. parts to cool. However, since electric vehicles have canceled the traditional internal combustion engine, they cannot rely on mechanical water pumps to provide cooling. Under this background, automotive electronic water pumps came into being. [0003] The controller in the existin...
