Problems solved by technology

With the increase of the vehicle-mounted water-cooling system, the head of the water pump is required to increase. However, traditionally, the power density of the water pump motor is limited by the heat load, and the power density is small. Moreover, the natural heat dissipation capacity of the water pump body is limited, and the power density of the water pump is limited.
At the same time, the water pump motor works at a high level for a long time, and its life will be shortened. In addition, the sealing problem of the water pump body and the motor body also tests the life of the water pump, restricts the pumping effect, centrifugally shakes the liquid, and the friction of the impeller , and the noise is larger

Embodiment Construction

[0032] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0033] As shown in the figure, the water pump is mainly divided into three parts, the casing part: water inlet 6, end cover 5, casing 2 and water outlet 11, stator part, stator 3, control module 1, plastic sealing layer 4, rotor part: rotor shaft 7. Rotor worm support 8, rotor magnetic steel 9 rotor iron core (with plastic sealing structure) 10.

[0034] The turbine water pump structure using low energy consumption permanent magnet brushless DC motor as power, as shown in the figure, the stator part of the water pump motor: After winding, install the stator assembly into the water pump casing, and use the plastic sealing process to seal the whole The stator is plastic-sealed. After plastic-sealed, a rotor cavity is formed inside the stator. After plastic-sealed, the stator-rotor air gap ...

Description

technical field [0001] The invention relates to an electronic water pump for vehicles. Background technique [0002] With the rapid development of new energy vehicles, in order to reduce the weight of the vehicle as much as possible and increase the mileage, the electric drive system requires higher functional density and smaller volume. However, it brings batteries, drive motors, and motor controllers. The high power density design of DCDC and other high-power devices brings many heat dissipation problems. In order to solve the heat dissipation problem, the water cooling system is used more and more widely, so the core component of the water cooling system - the water pump puts forward higher and higher requirements. , automotive electronic water pumps increasingly require low energy consumption, large head, high efficiency, low noise, small volume, long life and other characteristics. Today's water pumps basically use DC motors to drive the impellers to generate centrifuga...
