Embodiment Construction

[0018] The present invention will be further described below in conjunction with the accompanying drawings.

[0019] see figure 1 1. Distributed with cooling teeth 1 outside the motor housing 2, in order to increase the surface area and improve the heat dissipation capacity, the cooling teeth 1 are in the shape of a cuboid (certainly other shapes can also be taken). A sealing water jacket is installed on the inner side of the motor housing 2, and the water jacket is made of rubber material. When installed, it is integrated with the motor housing 2 and directly pressed on the water channel 3 to play a sealing role.

[0020] see figure 2 , The internal water channel 3 of the motor has a spiral shape and is arranged on the surface of the motor inner shell.

[0021] see image 3 , the structure of the detachable water inlet and outlet nozzle 4 is shown in the figure. combine figure 1 It can be seen that the water inlet and outlet nozzles 4 are distributed at 90°, installed w...

Abstract

The invention provides a driving motor with a heat dissipation structure for a pure electric vehicle, which comprises a motor body and the heat dissipation structure, wherein the heat dissipation structure comprises heat dissipation teeth, an outer motor shell with a sealing water jacket, a cooling water channel, a water inlet tap and a water outlet tap, and the heat dissipation teeth are distributed on the surface of the outer motor shell; the water jacket for sealing is arranged at the inner side of the outer motor shell in a pressing way, and the cooling water pipe is in a spiral shape, is distributed on the surface of the inner shell of the motor and is sealed by the water jacket at the inner side of the outer motor shell; and the water inlet tap and the water outlet tap are arranged on the outer motor shell, and a water inlet is connected with a motor controller in series and a water outlet is additionally connected with a radiator in series to form a liquid cooling circulating path. The invention reasonably utilizes a spatial structure in an engine compartment to cleverly design the positions and installation modes of the motor shell, the motor water channel, the water inlet and the water outlet, the cooling structure is simple and convenient to install, and the heat generated by the motor is taken away under the action of a cooling water pump and the radiator so as to achieve the purposes of rapid cooling and heat dissipation.

Description

technical field [0001] The invention belongs to the technical field of automobile drive motors, and in particular relates to a pure electric automobile drive motor with a heat dissipation structure. Background technique [0002] The driving motor of a pure electric vehicle is located in the engine compartment. When the motor runs for a long time or operates under conditions that require a large motor power, the motor generates high heat. In order to ensure the normal operation of the motor, a good heat dissipation structure is required Cool the motor. [0003] Most of the existing drive motor systems for pure electric vehicles use air-cooled heat dissipation, which has a low heat dissipation capacity. However, some adopt water-cooling heat dissipation method, and the water channel structure and the installation and arrangement of water nozzles are unreasonable, so that the heat generated by the driving motor cannot be dissipated, and the temperature of the motor rises, resu...
