Active fan for motor of coal feeder

The invention provides an active fan for a motor of a coal feeder, which comprises a water tank, the water tank is connected with the input end of a water pump through a hose, the output end of the water pump is connected with a plurality of input ends of a fan cooling mechanism through a plurality of hoses, and a plurality of output ends of the fan cooling mechanism are respectively connected with the water tank through hoses. Cooling water is conveyed into the evaporative cooling units, the cooling water is spread all over the whole evaporative cooling block under the capillary action, preliminary cooling is achieved, the cooling water in the evaporative cooling block is accelerated under the cooperation of the two sets of fan units, the cooling efficiency is improved, and the cooling effect of the evaporative cooling block is improved. A large amount of heat is taken away through evaporation, and the coal feeder motor is further cooled; meanwhile, as the water demand is not high and the wind power demand i
