High -power natural cooling formula fairing

The utility model discloses a high -power natural cooling formula fairing, including box, base plate, rectifier bridge, control circuit board, apron, first fin, heat pipe, second fin, during operation, the heat that rectifier bridge and base plate contact surface department produced passes through heat pipe fast transferring and gives the second fin, carries out the heat exchange by second fin and air and carries out natural cooling, owing to the rectifier bridge is steady relatively along the heat with the transmission of base plate contact surface peripherad, can carry out natural cooling through first fin and air. The device simple structure, the heat that can be quick effectively produces rectifier bridge work taken away, and not only the radiating effect is good, and waterproof performance is good moreover, reaches IP65 protection level, has noiselessness, advantage such as small, with low costs simultaneously.
