Description

Technical Field

[0001] The utility model relates to the technical field of motors, in particular to a high heat dissipation structure of a ventilator for a motor. Background Art

[0002] At present, the demand for variable frequency speed regulating motors and high power and high efficiency motors in various industries is increasing, and forced ventilation cooling of motors has become a development direction. For motors that require forced ventilation cooling, centrifugal fans are generally used for blowing or exhausting. The fan and the motor are independent of each other and connected for ventilation through an interface. The ventilation method is single and the ventilation efficiency is low, which easily leads to uneven temperature distribution in the motor.

[0003] The technical solution adopted in a motor ventilation structure of patent number: CN204290615U can achieve: the fan in the motor ventilation structure is embedded in the motor body, and the fan is combined with the motor, which solves the problem of easy heating and uneven heat dissipation of the motor. Both the blowing method and the exhaust method can be used to achieve the effect of "one machine for multiple uses";

[0004] Although the above scheme can achieve the purpose of uniform heat dissipation, its installation method has certain defects. The two ventilation structures are arranged on one side of the casing, which cannot improve the efficiency of air circulation inside the casing. At the same time, the ventilation structures are not protected. Therefore, collisions will cause damage to the ventilation structures and reduce their service life. Therefore, we propose a high heat dissipation structure for a motor fan that is easy to protect the ventilation structure and install in an offset manner to solve the above problems.
