Abstract

PURPOSE: To improve cooling efficiency by providing fins all over the metal member and sealed tubing composed of a main part and branch set internally and filling it with prearranged volatile working liquid and its vapor.
CONSTITUTION: Working liquid temperatures rise within the main part 3' of sealed tube passage 3 located near a heating element. As a result, the liquid is evaporated, absorbing evaporation latent heat. The vapor climbs up through branch 3 and is cooled due to lower temperatures of the wall surface than the main part being attributed to the back part fins 4. The cooled vapor condenses on the wall, conducting heat. The condensate descends being restored to the main part 3'. At that time, the heat conductivity is so significantly high that heat resistance can be reduced to approximately one several hundredth on a metal member of the same size. This fact allows the availability of compact, light-weight radiators. They are used by installing their mounting face 2 on the heating element. Under this constitution, the tube passage part can be formed by roll-sealing processing, so that their manufacture is easy.
