PURPOSE:To obtain a solar heat collector whose heat abosrbing efficiency is high, by employing heat collecting pipes made of fibrous material. CONSTITUTION:A rectangular body 1 has an air inlet 2 and an outlet 3 at the opposite ends of the length which are connected with conduits 4, 5 respectively, a heat insulator 9 is provided on the inner surface of the body 1, and a light transmitting plate 10 extends throughout the top of the body 1. A moistureproof film 14 is attached on the surface of the heat insulator 9, and a plurality of the heat collecting pipes 15 are juxtaposed in communication with headers 2, 3. Each heat collecting pipe 15 is for example made of thin fiber glass that has been woven into porous fabric whose outer surface has been covered with a lightly colored synthetic resin coat and which has been formed into a cylinder. |
