ABSTRACT:
A heating chamber is defined by canted side walls in inverse pyramidal configuration, the base of the pyramid being open for admission of sunlight and the tip of the pyramid being truncated by a bottom plane. The chamber is adapted to positioning with the aperture plane generally normal to the rays of sunlight so that the canted walls may be fully and simultaneously exposed to sunlight. The inner wall surfaces are dull-blackened to enhance conversion of shortwave solar energy to long-wave or infrared energy whereby the walls are heated so as to radiate infrared (heat) energy for transfer of such heat energy to objects or materials which may be positioned within the heating chamber. The chamber aperture is closed by translucent material such as glass for enhancing the heating effect of the black interior wall surfaces. The aperture closure may rest freely over the aperture or may be hinged along one edge for convenience of opening for access to the interior of the chamber. The chamber walls are preferably insulated exteriorly to inhibit conductive loss of thermal energy from the chamber. The effective aperture area may be increased by positioning reflective surfaces exterior of the heating chamber so as to direct additional sunlight against and substantially perpendicular to the black interior walls of the chamber whereby the temperature of such walls is further raised through absorption of solar energy and conversion thereof to heat for infrared radiation within the heating chamber.
