Patent ID: 8119271

Claim:
An electronic device comprising: a housing; a battery compartment in the housing, wherein the battery compartment is isolated by a bulkhead and is configured to accept a battery comprising a battery cell; a battery cover including a body including an external surface, an internal surface, and a convective heat transfer device on the external surface of the battery cover, the body having a thickness between the internal surface and the external surface of about two millimeters, the convective heat transfer device formed to increase the surface area of the external surface of the battery cover; a conductive heat transfer device on the internal surface of the battery cover, wherein the conductive heat transfer device is formed of a softer material than the battery; a latch assembly for coupling the battery cover to the housing, wherein actuating the latch assembly compresses the conductive heat transfer device against the battery and further compresses the battery cover against the conductive heat transfer device, wherein the conductive heat transfer device, the body of the battery cover, and the convective heat transfer device form a heat transfer path from the battery to the environment; a gasket interposed between the battery cover and the housing, wherein the battery cover, the gasket and the bulkhead seal the battery compartment; and wherein the outer surface of the battery cover defines a recess and wherein the convective heat transfer device is in the recess, wherein the convective heat transfer device comprises fins, rods or cylinders.
