Heatsink fixing structure of Speed controlling device for blower motor

摘要

The present invention is to shorten the process for fixing the base of the heat sink, simple yet so firmly fixed relates to a blower, a heat sink fixed structure of the motor speed control device and at the same time prevent any deviation. ; This subject innovation of the blower motor speed control device is a heat sink fixed structure of the heat blower motor speed control device sink according to a fixed structure, a base to form a through hole 114 formed in the bottom surface of the recess 112 in the upper surface of recess 112, 110; And, includes the aperture (114) being inserted into the through-fixing piece 126, a heat sink is mounted / fixed to the upper side of the base 110 to form a 120 in the bottom surface, the through hole of the base 110 ( 114) fixed to the front end side of the through the exposed heat sink 120, 126 is characterized in that the assembly is deformed by crimping the paper (G) leaving is prevented.
