Abstract
A thermally conductive coiled spring laid on its side provides a compliant, high conductive, low force thermal path between a heat source and a heat sink. Each spring contact provides two parallel heat conduction paths via each coil in the spring. The spring can be canted to permit slidable contact with a surface. In one embodiment a plurality of copper springs arranged in parallel can provide a thermal path between an electronic component and a heat sink in close proximity. The springs may be permanently attached to at least one surface at the points of contact.
