Abstract
A solar collector is described comprising an extrusion, preferably of cellular plastics material, having a longitudinally extending recess and a metal absorber sheet thereover, a tube disposed within the recess in contact with the metal absorber sheet, and a transparent window. The extrusion recess is of semi-circular cross-section, and the tube is of circular cross-section and has an outer diameter substantially equal to that of the recess. In some described embodiments, the window is received on flanges formed at the edges of the extrusion; and in other described embodiments, it is integrally formed with the plastics extrusion.
Claims9
A solar collector for heating a liquid by solar radiations, comprising:
- an extrusion having at least one straight longitudinally-extending recess formed therein of semi-circular cross-section;
- a straight tube disposed within the longitudinally-extending recess for the liquid to be heated by the solar radiations;
- said tube being of circular cross-section and having an outer diameter substantially equal to the diameter of the semi-circular recess;
- and a transparent window overlying the extrusion and the straight tube disposed within its recess, said extrusion being of plastics material, and the tube being of metal, the collector further including a metal absorber having a solar-radiation-absorbing surface facing said window, the metal absorber including a longitudinally-recessed portion underlying and in contact with the metal tube.
