PURPOSE:To obtain the heat-transfer equipment capable of being utilized for either the heat accumulator or the heat collector by providing a multitude of cells sealing operating fluid in the air-tight spaces thereof. CONSTITUTION:Each cell is formed by a method wherein an outer tube 3, having a larger diameter, is arranged at the outside of a tube 1 coaxially and bulkeads 4 of umbrella type are arranged between the tube 1 and the outer tube 3 in the same direction with spaces mutually. The operating fluid 5, condensed and evaporated at the using temperature of the heat-transfer equipment and selected from the group of substance of water, alcohols, organic substance or inorganic substance, is sealed in each cell 2 formed air-tightly around the tube 1. According to this method, in case the temperature of the wall surface of tube 1 has become sufficient to evaporate the operating fluid in the cell 2 and the temperature of the wall surface of outer tube 3 has become sufficient to condense the operating fluid in the cell 2, the operating fluid, being contacted with the wall surface of the tube 1, evaporates and the vapor is condensed and liquefied at the wall surface of the outer tube 3, then, the liquid is collected to the side of the tube 1 along the inclined bottom surface of the bulkhead, thus, one directional cycle is repeated in this equipment. This heat-transfer equipment can be used reversely in up-and-down direction, therefore, it may be used for the heat accumulator with excellent heat accumulating efficiency or the heat collector with excellent heat collecting efficiency by only converting the using direction of the equipment. |
