ABSTRACT:
A method and device for cooling engines and other heat sources having housings with fins protruding from a surface thereof for direct convective heat transfer with a fluid medium, particularly applicable for cooling engines constructed to be air-cooled. The invention features a cooling jacket having recesses defined in a surface thereof for receiving the fins of the housing of the heat source, and a coolant passage defined therein. The cooling jacket is placed in close proximity to the heat source housing, such that the fins of the housing of the heat source protrude into the recesses of the cooling jacket. The small gap between the contoured heat source and jacket surfaces is filled with a thermally conductive material to enhance heat transfer from the heat source to the jacket. The cooling jacket can be readily mounted to an assembled, commercially engine to transform the engine from air-cooling to liquid-cooling.
