Motor cooling system for new energy automobile

Abstract

The invention provides a motor cooling system for a new energy automobile. The motor cooling system for the new energy automobile comprises a motor controller, a gear box and a motor, wherein the motor controller, the gear box and the motor are closely connected to form an integrated overall structure and arranged in sequence. A water box is arranged at the exterior of the gear box. The motor comprises a machine shell, and a conical tube is arranged in the middle of the motor in the axial direction in an inserting mode. The gear box comprises a left box body and a right box body, wherein the left box body and the right box body abut against the motor and the motor controller correspondingly. The motor controller comprises at least one radiator. Water sent from the water box enters the radiator from a water inlet of the right box body through a channel. Water flow discharged from the radiator enters the left box body again through a water outlet of the right box body. Water flow discharged from the left box body passes through the machine shell and flows back to the water box finally. Part of water in the connection position of the water box and the right box body passes through the left box body from an inlet of the surface of the right box body, then passes through a pipeline, enters the conical tube, and flows back to the water box finally under actions of pressure and gravity. The motor cooling system for the new energy automobile has the advantages of being compact in structure, reliable in working and good in stability.

Description

technical field [0001] The invention belongs to the technical field of motor cooling for new energy vehicles, and relates to a motor cooling system for new energy vehicles. Background technique [0002] Now the smog is serious, most of it is due to exhaust emissions. If the exhaust gas is controlled, it will benefit future generations, and now our country’s crude oil reserves are very tight. Once cut off, they can only be used for 11 days. Under the background of environmental protection and energy conservation, The development of new energy vehicles is the general trend, and new energy vehicles have received more and more attention. [0003] Considering the comfort of passengers and the limited installation space of components in the car, motors and motor controllers are also constantly developing towards the trend of small volume and high power density. New energy motors with high power density and motor controllers have high heat dissipation pressure and long circulating...

AI Technical Summary

Problems solved by technology

This water-cooled new energy vehicle has the following problems: 1. There are too many pipes, and there are many hidden dangers of failure; 2. Due to the scattered arrangement of the water-cooling system, the water path is too long and the cooling efficiency is low; 3. The structure is not compact and installation and maintenance is not convenient
