Abstract
Individual collector cells are fitted together in series along a tube through which a heat transfer medium flows. Each cell has a cylindrical housing shell with openings at both ends offset from the cylindrical axis and bordered by flanges, so that the narrow opening of one cell may fit into the wider opening of the next, with a gasket in between. Thus, the two cells joined at the junction may be supported on the tube that passes through both. The half of the cylindrical shell on the side of offsetting of the openings is provided with a reflecting surface, either coated on the outside of the shell or provided in one way or another on the inside. The assembly of cells may be adjusted by rotating about the tube so that the direction of arrival of sunlight is perpendicular to the mirror aperture. The individual shells are made by making a bottle on a bottle-making machine, with the closed end of the bottle being formed in such a way that by scoring a circle and applying a sharp blow, a disk may be knocked out to provide the second opening.
