Background

Fans are widely used for dust removal and cooling in factory and mine ventilation, and for ventilation and draught of boilers and industrial furnaces. The fan is a device which is driven by a motor and rotates with an impeller to realize ventilation. The time of the fan when in use is almost all very long, and because the continuous rotation of the rotating shaft, the fan bearing seat provided with the rotating shaft generates a large amount of heat. And the heat can not be dissipated, so that the motor or the whole fan is easily burnt out, and potential safety hazards are caused. Therefore, the existing fan bearing seat is provided with a water cooling channel beside the bearing, and the fan bearing seat is cooled through a water circulation device.

Then when there is a large amount of heats in the fan bearing frame, the heat can be in the conduction between each part of fan bearing frame, and current water-cooling structure often only sets up by the bearing again, so fan bearing frame uses back for a long time, and structures such as the shell in its middle part still have higher temperature. Therefore, the existing cooling structure of the fan bearing seat still has an improved space.
