ABSTRACT:
Apparatus for heat transfer is disclosed. This apparatus is a closed container which is possessed of an input portion and an output portion for heat energy and is provided on the inside thereof with a wick extending throughout from the input portion to the output portion and disposed so that the resistance offered thereby to the flow of liquid gradually decreases from the input side to the output side. The heat medium which is vaporized on the input side is moved in the direction of the output side by virtue of the difference of pressure created inside the container. The heat medium which is deprived of heat and consequently liquefied on the output side is moved within the wick in the direction of the input side by virtue of capillary action coupled with the suction resulting from the vaporization of the heat medium in the input portion. As the temperature on the input side falls below that on the output side, the movement of the heat medium in the direction of the input side discontinues because of the stop of the vaporization of the heat medium on the input side and the directionality of the resistance offered by the wick to the flow of liquid, preventing otherwise possible reverse flow of the heat energy.
