Abstract

A cooling and heat dissipation device installed on a motor casing, belonging to the technical field of motors; the present invention aims to provide a motor heat dissipation device with a wide application range and high heat dissipation efficiency; the present invention includes a heat dissipation sleeve and a heat dissipation sleeve installed above the heat dissipation sleeve The tube group, the cooling sleeve is a cavity structure, and the cooling sleeve is filled with coolant. The cooling tube group is composed of a number of cooling tubes. The cooling tube is a hollow tubular structure with both ends open, and the cooling sleeve is attached to the motor casing. The outer surface of the heat dissipation pipe is connected with the heat dissipation sleeve at both ends, and there is a heat dissipation gap between the pipe body of the heat dissipation pipe and the outer wall of the motor casing; the traditional heat dissipation structure such as the traditional motor coaxial fan replaced by the present invention has a simple structure , The installation size is small, and the electromagnetic load of the motor is further increased to improve the power density.

Description

technical field [0001] The invention belongs to the field of motor heat dissipation, and mainly relates to a novel cooling and heat dissipation device installed in a motor casing. Background technique [0002] At present, high power density motors and high electromagnetic load motors generate severe heat due to their high electromagnetic loads and large losses. In actual operation, there are strict requirements on the temperature rise of the motor, so it is necessary to improve the cooling structure to improve the heat dissipation efficiency. Not all motors are available with water cooling, oil cooling or special internal cooling structures. The invention adopts the cavity heat dissipation sleeve, has a simple structure and is convenient for installation, and is suitable for various rotating electrical machines with high heat dissipation requirements. Contents of the invention [0003] In order to solve the problem that the heat dissipation device of the motor in the pri...
