Improve and replenish as the further of said structure, the utility model also comprises the combination in any of following additional technical feature or these features:
Described shell one side is provided with the hollow cylindrical projection, and described stator is a hollow circular cylinder, and described projection is located in the hollow part of stator, plays the effect of location; Described shell opposite side periphery is provided with annular outer ring, and described thermal conductive silicon film, circuit board and enclosing cover are arranged in the outer ring of shell, makes internal components not exposed outside, improves operation stability.
Described heat radiation sponge has a plurality of and is circumferentially uniform, further improves heat-conducting effect.
Described heat radiation sponge is a rectangular shape, rationally utilizes heat radiation sponge shape fully to enlarge thermal conductive surface, increases heat-conducting effect.
A kind of improved outer rotor blower fan utilization heat radiation sponge that the utility model obtains is connected power device with shell heat conduction, the heat that sends when power device is moved in time is dispersed into the external world, only adopt heat conductive silica gel to compare with former scheme, the power device surface temperature descended 5 the degree, efficiently radiates heat, improve the working life of power device, strengthened the stability of outer rotor blower fan operation.
