Abstract:
A heat transfer device for dissipating heat, the device comprising:a plurality of air heat exchange structures arranged for heat exchange with ambient air; a heat pipe structure comprising at least one thermally conductive envelope containing a working fluid for distributing heat energy wherein the heat exchange structures comprise a plurality of spaced fins formed with openings that substantially align with one another and are disposed alone an outside edge of the stack so as to be aligned to define a channel, wherein said channel has a reduction in channel width approaching the outside shape, and wherein the conductive envelope is snap-fittable into the channel for structurally supporting the fins and further wherein the fins are complementary with an outside shape of the conductive envelope and arranged in a stack, so as to be substantially exclusively supported by the at least one thermally conductive envelope; wherein the thermally conductive envelope of the heat ripe structure substantially defines a mounting base for the heat transfer device, the envelope of the heat pipe structure being attachable to a heat source for thermal energy exchange by conduction with the heat source, and wherein the heat pipe structure supports the heat exchange structures in thermal relation with the conductive envelope; wherein the conductive envelope also has a flattened surface facing outwardly from the channel.
