Technical Field

The invention relates to the technical field of automobile motors, in particular to a new energy automobile motor.

Background

The motor of the electric/hybrid electric vehicle generates a large amount of heat in the working process, the temperature of an engine or a gearbox connected around the motor is also high, and the heat on the motor is transferred to the motor, so that the temperature of the motor is further increased, the performance and the efficiency of the motor are seriously affected, and the motor needs to be radiated.

Disclosure of Invention

The invention aims to provide a new energy automobile motor to solve the problems that the motor in the prior art is poor in cooling effect and inconvenient to dissipate heat and transport.

In order to achieve the purpose, the invention provides the following technical scheme:

a new energy automobile motor comprises a cylindrical water-cooling shell, wherein end covers are connected to two ends of the water-cooling shell, end cover radiating grooves are formed in the end covers, a plurality of annular water channels are formed in the water-cooling shell, the water channels are communicated with a water inlet pipe and a water outlet pipe, and the water passing area of the water channels can be adjusted by adjusting the width of the water channels; and a shell radiating groove is formed in the outer part of the water cooling shell.

The principle and the beneficial effect of the scheme are as follows:

the water course is used for supplying the cooling water to flow, and the inlet tube is used for pouring into the cooling water into the water course, and the outlet pipe is used for discharging the cooling water in the water course, makes the cooling water at this internal loop of casing from this, takes away the heat of motor through the cooling water, realizes the cooling heat dissipation of motor. Under the condition that sets up annular water course, the thickness that adopts the water-cooling casing of tube-shape can the at utmost reduce the water-cooling casing to reduce the weight and the volume of water-cooling casing, be convenient for dispel the heat and transport.
