ABSTRACT:
Heat dissipation structures formed from folded sheet metal are described. The structure permits close thermal contact to a heat generating surface by permitting independent movement of fins or fin assemblies. The fin assemblies are spring biased towards the heat generating surface by a spring means which is disposed between the tops of the fin assemblies and a cover which forms a duct surrounding the fin assemblies for holding the fin assemblies together and for permitting a fluid, such as air, to be channeled over the fin assemblies. The cover has grips for gripping onto the side portions of the heat generating surface. Furthermore, the cover has means for gripping onto the spring bias means for fixedly attaching it thereto. Furthermore, the fin assemblies have means for engaging with the bias means for holding the fin assemblies in fixed special relation with the spring bias means. The fin assemblies, spring bias means and cover form a unitary structure which can be detachably mounted or snap fit onto a heat generating surface, such as a semiconductor chip module.
