Description

Technical Field

[0001] The utility model relates to the technical field of electromechanical auxiliary equipment for coal mines, in particular to an electromechanical cooling device for coal mines. Background Art

[0002] Large equipment such as ventilators, air compressors, and hoists used in coal mine production all require matching motor drives. These motors generate a lot of heat during operation. Dissipation under natural conditions alone is far from meeting the motor cooling requirements, resulting in increased temperatures, which seriously affects the working conditions of coal miners and the service life of the machines.

[0003] Coal mine motors generate a lot of heat during operation, and the natural heat dissipation is relatively slow, so interference is needed to improve the heat emission. Generally, a cooling device is used to achieve rapid temperature emission. However, the existing cooling device generally uses exhaust. However, due to the residual oil stains at the tail of the coal mine motor, impurities are easily adhered, causing blockage and making it difficult to discharge. For this reason, we designed a coal mine electromechanical cooling device that can simultaneously clean the tail of the coal mine motor while enhancing heat dissipation. Utility Model Content
