Abstract
A device for transferring heat from a device component to an environment includes a heat plate connected to a spring. A first fastener attaches the spring to the heat plate at a first location. A second fastener, such as a rivet, attaches the spring to the heat plate at each of a second and a third location. The second fastener includes a tab on and extending above the heat plate and corresponding tab slot on the spring. The spring is riveted to the heat plate at the first location and a second spring member accepts the tab at each of the second location and the third location. Ribs on a top surface of spring facilitate thermal coupling of the spring to the component when the device is assembled. One or more spring curvatures facilitate vertical deflection and horizontal extension of the spring during device assembly.
