A heat dissipation structure of a tire repairing machine (A) is disclosed. A fixing seat (2) with at least one channel (23) is provided in a main body (1). Two ends of the channel (23) are channel inlet (231) and channel outlet (232), respectively. A gas supply unit (3) provided in the main body (1) includes a motor (31) and an air compressor (32) driven by the motor (31). The motor (31) is located in the fixing seat (2), so that a centrifugal fan (4) connected to the driving shaft of the motor radially faces to the channel inlet (231), and the air compressor (32) faces to the channel outlet (232). While the motor (31) drives the air compressor (32), the centrifugal fan (4) pumps and directs air to the air compressor (32) by the channel (23), so as to dissipate the heat of the air compressor (32). |
