Abstract

PURPOSE:To obtain a heat-collecting medium device having a high heat- collecting efficiency, by providing a heat insulating material so as to surround the side face of a high-collecting medium having enlarged and decreased end faces. CONSTITUTION:A heat-collecting medium 1 formed of a good heat conductor has an enlarged end face 2 closely contacted with the surface of a wall 4 of a high-level heat source 3 and has a decreased end face contacted with a low- level heat source 6. The side face 7 of the heat-collecting medium 1 is surrounded by a heat insulating material 8. The enlarged end face 2 has a rectangular shape and an area of 2al, while the decreased end face 5 has also a rectangular shape and an area of 2bl. Provided that the quantity of heat transmitted from the heat-collecting medium 1 to the heat insulating material 8 is negligible, that is, provided that the heat insulating material 8 can insulate heat perfectly, the quantity of heat QH given by the wall 4 of the high-level heat source 3 to the heat-collecting medium 1 is equal to the quantity of heat QC given by the heat-collecting medium 1 to the low-level heat source 6. Accordingly, a heat-collecting action can be properly attained by collecting or diffusing the heat flow by means of these enlarged and decreased end faces.

A high heat source 180 , for example a heat collecting fin 181 exposed to the outside air, is disposed on the enlarged end surface 179 of the second heat collecting medium 177 . A side surface 182 of the first heat collection medium 169 and a side surface 183 of the second heat collection medium 177 (surrounded by a heat insulating material 184).

As is clear from the above description, the heat collecting medium suspension device of the present invention achieves the appropriate heat collecting action by converging and diffusing the heat flow using the enlarged end face and the contracted end face.
