Abstract:
1. A heat transfer apparatus comprising: a thermally conductive member including a base having one or more surfaces adapted to absorb heat from an electronic component and one or more surfaces extending from the base to radiate absorbed heat; and, a mounting assembly including at least one mounting member directly coupled to the base and for direct attachment to the electronic component so that loading forces for mounting on it the electronic component are not directly applied to the base; further comprising a compliant force applying mechanism mounted generally on the base for controlling forces applied on the base; wherein the compliant force applying mechanism includes at least a biasing element, and a force applying actuator member; wherein the biasing element is a coil spring is disposed about a shaft of the actuator member between lateral edges of the member and the top of the base, the actuator member comprises a pair of radially extending arms, each of which has an opening for receiving a threaded member which is received by the mounting assembly, whereby by adjusting the threaded members, the actuator member can adjustably compress or relax the coil spring so as to adjust the force on the center of the base.
