Abstract

The invention discloses a heat dissipation structure of a motor, which comprises a water-cooled housing, an end cover and an air-cooled housing. On the shell; the side wall of the water-cooled shell is provided with a ring-shaped water-cooled flow channel, and the outer end surface of the water-cooled shell is provided with a liquid inlet and a liquid outlet connected with the water-cooled flow channel; the wind The cold shell is a structure with the left end closed and the right end open. A shaft hole is provided at the center of the left end face of the air-cooled shell, and a bearing positioning protrusion is provided on the inner wall of the shaft hole; There are a first circular protrusion and a second circular protrusion arranged coaxially with the shaft hole, and the inner diameter of the first circular protrusion is equal to the diameter of the shaft hole. The cooling effect of the invention is good, and the maintenance and replacement of the cooling fan are convenient.

Description

Technical field: [0001] The invention relates to a motor cooling structure. Background technique: [0002] Motors are used in all kinds of machinery. The motors often have small fans for heat dissipation. The cooling effect of the fans is limited. In high temperature environments, the effect is even less obvious. In addition, the heat dissipation fans of the existing motors are equipped with stators and rotors. In a cavity, when replacing or repairing the cooling fan, the whole rotor needs to be pulled out to complete the maintenance process, so the rotor or stator will be damaged unintentionally. [0003] Therefore, it is necessary to improve the prior art to solve the deficiencies of the prior art. Invention content: [0004] The present invention provides a heat dissipation structure for a motor in order to solve the above-mentioned problems in the prior art. [0005] The technical solutions adopted in the present invention include: a motor heat dissipation structure,...
