Embodiment Construction

[0013] The present invention will be further described below with reference to the accompanying drawings and embodiments, and the mode of the present invention includes but not limited to the following embodiments.

[0014] The purpose of this embodiment is to provide a motor with high heat dissipation efficiency. The motor includes a housing and a stator 100 , a chamber is defined in the housing, and an inlet and an outlet communicating with the chamber are provided on the housing. The stator 100 is arranged in the chamber, and a cooling channel is defined between the outer wall of the stator 100 and the inner wall of the housing, and the inlet and outlet are respectively communicated with the cooling channel. The heat exchange channel is set between the housing and the stator 100, and is formed by the cooperation of the housing and the stator 100. The cooling medium enters the cooling channel through the inlet outside the housing, exchanges heat with the stator, and then flow...

Abstract

The invention discloses a motor with high heat dissipation efficiency. The motor comprises a shell, a rotor and a stator which are arranged in the shell as well as a front cover and a rear cover whichare arranged at the two ends of the shell, a cooling channel is formed in the outer wall surface of the stator and the inner wall of the shell, an inlet communicated with one end of the cooling channel is formed in the front cover, and an outlet conducted with the other end of the cooling channel is formed in the rear cover; multiple convex edges which extend along the axial direction of the stator and are spaced and arranged along the circumference are formed on the outer wall surface of the stator, a groove is formed between any two adjacently arranged convex edges, and the grooves form anS-shaped tank body which extends along the circumference of the stator and fluctuates up and down along the axial direction of the stator; and a vacancy is formed at positions corresponding to the convex edges on the inner wall surface of the shell, and any two adjacent grooves are conducted by virtue of the vacancy. The motor disclosed by the invention is short in thermal transmission path, largein heat dissipation area and high in heat dissipation efficiency.

Description

technical field [0001] The invention relates to the technical field of motors, in particular to a motor with high heat dissipation efficiency. Background technique [0002] The motor in the prior art adopts the indirect cooling technology, and the stator part of the motor is divided into a stator core layer, a casing solid layer and a water channel layer from the inside to the outside. The heat dissipation path is: the heat is first transferred from the iron core to the casing body, from the casing body to the water channel, and then from the water channel to the outside of the motor. The heat transfer path is relatively long and has many segments, so the heat dissipation efficiency is relatively low, and the structure of the motor is complicated and the cost is high. Contents of the invention [0003] The object of the present invention is to solve the above technical problems and provide a motor with high heat dissipation efficiency. The heat transfer path of the motor ...
