Self air cooling aerating/exhausting apparatus

The utility model relates to a self air cooling aerating/exhausting apparatus, comprising a motor seat and a rotary wheel seat, wherein, a motor seat is arranged in the motor seat, and the rotary wheel seat comprises two combined circular discs, a vane clamped between the two circular discs and a gas outlet arranged in the rotary direction of the vane. A gas sucking port is arranged in the bottom end of the motor seat, and the motor is arranged between the gas sucking port and the gas outlet. Outside air-current sucked from the gas sucking port can be exhausted through the gas outlet after flowing through the motor when the vane is driven to rotate by the motor in order to form an air cooling channel for continuously cooling the motor. The utility model has the efficiency of cooling the motor via a self body, and thus the aerating/exhausting apparatus having the advantages of favorable radiation effect and long service life is obtained.
