Embodiment Construction

[0025] Embodiments of the present invention will be described in detail with reference to the accompanying drawings.

[0026] like figure 1 As shown, a new type of cooling and heat dissipation device installed in the motor casing in this embodiment includes a heat dissipation sleeve 3 and a heat dissipation pipe group installed above the heat dissipation sleeve 3. The heat dissipation sleeve 3 is a cavity structure, and the heat dissipation sleeve 3 is filled with cooling liquid, and the heat dissipation pipe group is composed of several heat dissipation pipes. The heat dissipation pipe 2 is a hollow tubular structure with both ends open. The heat dissipation sleeve 3 is attached to the outer surface of the motor 4 shell. The two ends are respectively communicated with the heat dissipation sleeve 3, and there is a heat dissipation gap between the body of the heat dissipation pipe 2 and the outer wall of the casing of the motor 4. The motor 4 is connected and fixed with the mot...

Abstract

The invention relates to a novel cooling and heat dissipating device installed in a motor casing, and belongs to the technical field of motors. The invention aims at providing a motor heat dissipatingdevice with wide application range and high heat dissipating efficiency. The novel cooling and heat dissipating device provided by the invention comprises a heat dissipating sleeve and a heat dissipating pipe group installed above the heat dissipating sleeve, the heat dissipating sleeve is of a hollow cavity structure, the heat dissipating sleeve is filled with cooling liquid, the heat dissipating pipe group is composed of a plurality of heat dissipating pipes, each heat dissipating pipe is of a tubular structure having two open ends and a hollow interior, the heat dissipating sleeve is attached to an outer surface of the motor casing, the two ends of each heat dissipating pipe communicate with the heat dissipating sleeve, and a heat dissipating gap is reserved between the pipe body of each heat dissipating pipe and an outer wall of the motor casing. The novel cooling and heat dissipating device provided by the invention replaces the conventional heat dissipating structures such as aconventional motor coaxial fan and the like, has a simple structure and a small installation size, further increases the electromagnetic load of the motor, and improves 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...
