PURPOSE:To make it easy to take out the heat collecting elements and increase the heat discharge area of heat discharge units by screwing a plurality of heat collecting elements on a heat medium pipe so that their heat discharge units project inside the heat medium pipe. CONSTITUTION:When heat receiving units 8a of heat pipes 8 enclosed in heat collecting elements 6 are exposed to solar rayes, operating liquid (water, Freon or ethylene glycol) in heat pipes 8 is heated and evaporates. This vapor moves into heat discharge units 8b, where it condenses and discharges its latent heat and heats the heat medium. The condensed operating liquid falls into heat receiving units 8a by gravity, and it is heated by sun rays and evaporates again. When any of these heat collecting elements 6 is broken or damaged, the heat discharging unit 8b of heat pipe 8 is taken out from helical cylinder 5 of the heat medium pipe 1 by turning that heat collecting element, and it is possible to replace the heat collecting element 6 only. |
