Abstract: A spring clip that has rocking and force profiles with attachment configurations is disclosed. The spring clip made out of spring quality material such as stainless steel and the spring clip includes special provisions for mounting a cylindrical cooling device (i.e. a heat sink). Swinging arm principles are used to form force profiles that ensure that a load center of the clip is always on a fulcrum axis thereby focusing the force of the clip on a required load axis. The spring clip can accommodate higher manufacturing deviations without sacrificing the functional requirements. Moreover, the spring clip allows the heat sink to be inserted and then rotated in order to mount the heat sink on the component to be cooled thereby ensuring easy insertion of the heat sink and easy removal of the heat sink when the component being cooled requires replacement or repair. The spring clip can be manufactured at a low cost using stamping and forming processes.

Abstract: A low-cost, fan assisted cooling device is disclosed. The cooling device includes a narrow bottom and broad top shape to optimize a material versus performance ratio. A plurality of vanes surround a central heat mass and an inside surface of the vanes define a chamber that surrounds the heat mass. A portion of each vane is split into a plurality of fins and both the vanes and the fins have a surface area that increase in a radially outward direction from an axis of the heat mass. The heat mass includes a boss that is surrounded by a groove. Both the boss and the grove have arcuate surface profiles. The vanes, the fins, the boss, and the groove efficiently dissipate heat when a fan or the like forces air into the chamber thereby producing air flows in three different directions. In a first direction, the air flows out of the chamber through the vanes. In a second direction, a low pressure region in the chamber induces air from outside the chamber to flow through the fins.
