Patent ID: 11943899

Abstract:
A heat-transfer component defines a thermal-interface surface and has a composite thermal-interface material on the thermal-interface surface. The composite thermal-interface material comprises a silicone oil substrate and a metallic filler. In some embodiments, the metallic filler undergoes a transition from solid to liquid at a temperature below a typical operating temperature of an electronic device. For example, an embodiment of a metallic filler has a solid-to-liquid transition temperature between about 25° C. and about 95° C. In some embodiments, a second thermal interface material extends around an outer periphery of the composite thermal interface material, which can inhibit or prevent seepage or other migration of metallic filler in the composite thermal-interface material out of a thermal interface region between the heat-transfer component and, e.g., a heat-generating component. Also disclosed are electrical devices having a heat generating component cooled by such a heat-transfer component.
