PURPOSE:To form the plate so as to receive the solar beams orthogonally before and after the noon to improve heat absorbing efficiency by a method wherein water introducing pipes are provided with fins therearound, a glass plate above the heat collecting plate is formed so as to be shevron or semi-circular type and the water introducing pipes are formed so as to be arranged in parallel to the glass plate. CONSTITUTION:The water introducing pipes 3 in the frame of the heat collecting plate 4 are provided with fins 2 around the outer peripheries thereof to improve the heat absorbing efficiency. The glass plate 1 above the heat collecting plate 4 is formed into shevron or semi-circular type and the water introducing pipes 3 are formed so as to be arranged in parallel to the glass plate 1. The device is formed so as to receive the solar beams orthogonally as possible in the morning and afternoon in order to improve the heat absorbing efficiency of the device. |
