Abstract:
A heat transfer apparatus comprising:a heat generating device having a heat dissipating surface, said heat generating device including a first flange on one side of the device and a second flange on an opposite side of the device;a platform;a heat conductive interface disposed between said heating dissipating surface and said platform, said heat conductive interface including a plurality of spaced apart heat conductive strips extending longitudinally in one direction along an area defined by said heat dissipating surface, said strips being separate from each other and forming spaces therebetween, each strip including a series of corrugations, wherein a plurality of bolts extend through the first flange and through openings in one end of the strips to be threadedly engaged into the platform and wherein a plurality of bolts extend through the second flange and an opening in an opposite end of the strips to be threadedly engaged into the platform so that pressure from securing the heat generating device to the platform by the bolts causes the strips to expand laterally into the spaces to form a nearly continuous heat conductive contact between the heat generating device and the platform in response to applying a compressive force securing the heat generating device to the platform.
