PURPOSE:To realize the compact structure and the high heat collecting performance steadily by a method wherein plural pipes having small diameter are arranged in parallel neary along an imaginary dividng surface which symmetrically divides the reflecting surface of a reflecting plate into two parts. CONSTITUTION:A fluid passage 3 is arranged in parallel with spacing small interval at the location where an imaginary dividing surface (a) divides the space. The fluid passage 3 is composed of five pipes 4, 5, 6, 7 and 8 coated with black paint, those pipes having small diameter are made of copper, the pipe 4 is arranged to be close to a reflecting surface 1. Even when the incident angle of the solar ray is varied according to the season and time, the large part of the solar ray reflected with the reflecting surface 1 is absorbed by any pipe among those pipes 4, 5, 6, 7 and 8, accordingly, excellent heat collecting coefficient can be achieved. |
