Gunderson, C F

A solar heat collector uses elongated, tubular, outer casings, in a fixed position with respect to the solar orbit, surrounding inner tubular sections, carrying heat-conductive fluid. The outer casings are highly transparent and the walls of the outer casings are of substantial thickness and of a high refractive index to admit solar heat energy and to focus it on or towards the inner tubular sections or tubes that are of highly conductive material and have dark, heat-absorbing surfaces. One of the sides of the outer casings faces toward the sun. The other of the sides of the outer casings are coated with a highly reflective material to reflect any solar heat energy that by-passes the tubes, back to the inner tubes. Each of the casings is mounted in a substantially vertical plane, and the solar heat collector would normally consist of a plurality of such casings, or units, mounted side by side in a fixed plane approximately normal to the noonday, winter sun, or perpendicular to the sun's orbit. The upper and lower ends of the tubes are connected to a system for storing or using the heat-conductive fluid after it is warmed by the solar energy.
