Abstract
A heat transfer system between a heat source and a heat sink, wherein the heat transfer contact surfaces comprise a metal which forms numerous voids when placed adjacent one another. A thermal pad comprising a polymer filled with ceramic particles is placed between these heat transfer surfaces to intimately contact each of the metal surfaces without void formation, thereby increasing thermal conductivity. The heat source and heat sink are joined by relative sliding motion. This sliding motion might damage the thermal pad. Thus, a hot swap structure is provided for controlling the movement of the thermal pad into contact with the heat source as the sliding motion is completed.
Claims15
A hot swap structure for transferring heat between a heat source and a heat sink comprising:
- a metal piece;
- a lever, the lever being mounted to be operatively engageable with the metal piece;
- a leading edge on the metal piece, and an actuation of the lever also causing the leading edge to exert a force on a framework to cause the framework to urge the heat sink into intimate contact with a thermal pad;
- and
- the framework for supporting the lever and the metal piece,
- wherein relative sliding motion between the heat source and the heat sink actuates the lever to urge a thermal pad into contact with the heat source.
A heat transfer system between a heat source and a heat sink comprising:
- a thermal pad between the heat source and the heat sink, wherein the heat source and the heat sink are joined by relative sliding motion;
- and
- a hot swap structure to urge the thermal pad into contact with the heat source and simultaneously urge the heat sink into contact with the thermal pad the hot swap structure comprising a framework, the framework holding a plurality of metal pieces, the trailing edge of each of the metal pieces in contact with a lever,
- wherein the lever is actuated by contact with the relatively moving heat source,
- wherein the actuation of the lever forces the thermal pad into contact with the heat source,
- wherein the actuation of the lever simultaneously forces the heat sink into contact with the thermal pad.
