PURPOSE:To permit to collect the solar heat highly efficiently with a comparatively simple and inexpensive device by a method wherein the evaporator of a heat pump is arranged at the downstream side of the radiating fin of heat pipe device and atmospheric air is sent by a fan. CONSTITUTION:When weather is fine, solar light permeates a transparent cover 2, is absorbed by the absorption film 7 of a heat collecting panel 6 and heats the evaporating unit 10 of the heat pipe device 9. Liquid operating fluid 13 in the evaporating unit 10 is boiled and evaporated by the heating and moves to a condensing unit 11 having slightly lower 12 by the fan 17 and the operating fluid 13 in the condensing unit 11 releases the latent heat of condensation. Liquefied operating fluid 13 returns to the evaporating unit 10 again and this circulation is continued as far as the sun shines. The circulating amount of operating fluid in the pipe of the heat pipe device 9 is decreased as the amount of sun shine is reduced and is stopped when a condition, determined by the amount of sun shine and an atmospheric temperature, has been brought, thereafter, an evaporator 14 absorbs the heat only from atmospheric air sent by the operation of the fan 17. |
