Motor heat dissipation equipment for axial flow fan

Abstract

The invention discloses motor heat dissipation equipment for an axial flow fan. The motor heat dissipation equipment for the axial flow fan comprises a mounting cylinder, a fixing block fixedly connected in the mounting cylinder and used for supporting and fixing the motor heat dissipation equipment, and a driving component comprising a heat dissipation cavity, supporting plates and a driving motor; the two supporting plates are fixedly connected to the two ends of the upper surface of the heat dissipation cavity respectively, a water storage cavity and a placement cavity are formed in the heat dissipation cavity, the heat dissipation cavity is fixedly connected to the fixing block through a fixing plate, the driving motor is fixedly connected to the top ends of the two supporting plates, fan blades are arranged at the driving end of the driving motor in an annular array mode, and the driving component is used for providing power when the heat dissipation equipment works. According to the heat dissipation equipment, when a sealing plug moves, water in the sealing cavity is pushed to enter the water spraying cavity through a water drainage pipe to be sprayed to the lower portion of the driving motor and water absorption cotton, and therefore the heat dissipation effect on the driving motor is achieved.

Description

technical field [0001] The invention relates to the technical field of driving motors, in particular to a motor cooling device for an axial fan. Background technique [0002] Electric fans are generally divided into two types: standard popular type and electronic luxury type. The former is characterized by simple structure, convenient operation and low price. Generally, it only has two functions of speed regulation and changing wind direction. Features, luxurious and exquisite shape, consumers can choose according to the premise of practicality or practicality and decoration. [0003] The fan is often used in a hot environment, so it is easy to generate a lot of heat when driving the motor for a long time, and its own heat dissipation is limited, which in turn causes damage to the internal circuit of the motor and severe wear of the bearing and other components, which not only increases the number of repairs, At the same time, it has more influence on the normal operation o...

AI Technical Summary

Problems solved by technology

[0004] The purpose of the present invention is to solve the following shortcomings in the prior art. The fan is often used in a relatively hot environment, so the driving motor is likely to generate a lot of heat under long-term work, and its own heat dissipation is limited, which in turn causes damage to the internal circuit of the motor and The heavy wear of bearings and other components not only increases the number of repairs, but also affects the normal operation of the factory building. A motor heat dissipation device for axial fans is proposed
