Active fan for motor of coal feeder

The utility model provides an active fan for a motor of a coal feeder, which comprises a water tank, the water tank is connected with an input end of a water pump through a hose, an 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. According to the utility model, cooling water is conveyed into the evaporative cooling unit, and the cooling water is spread over the whole evaporative cooling block under the capillary action, so that primary cooling is realized; cooling water in the evaporation cooling block is accelerated under the cooperation of the two fan units, a large amount of heat is taken away through evaporation, and the motor of the coal feeder is further cooled; meanwhile, as the water demand is not high and the wind power demand is not high, the water pump and the fan are both low-power equipment, and
