duct 50 first ends of the plurality of heat pipes 62 a 62 b 62 c 62 d 62 e would be mounted so that the flow of air passing through the cooling air duct 50 flows over the first ends of the heat pipes this would allow the first ends of the heat pipes to absorb heat from the flow of air passing through the cooling air duct 50 in the embodiment shown in fig3 the second ends of the heat pipes are located in a heat exchanger 70 and a flow of ambient air or some other cooling media passes across the second ends of the heat pipes to remove heat from the second ends of the heat pipes the flow of coolant passing through the heat exchanger 70 could be ambient air fuel gas cooling water or some other type of media in alternate embodiments of the invention heat could be removed from the second ends of the heat pipes using a different type of heat exchanger 70 for instance a flow of a liquid or a gas through the heat exchanger 70 could also be used to remove heat from the second ends of the heat pipes in still other embodiments the second ends of the heat pipes could be embedded in a solid heat conducting material and the solid heat conducting material could be placed in a liquid or gas flow that serves to remove heat from the second ends of the heat pipes also as described above the heat removed from the second ends of the heat pipes.
