ABSTRACT:
A portable solar heating panel adapted for use in drying grain in the season thereof and for use for heating buildings or like heating purposes in the off season, is made of a double-glazed window spaced from an imperforate accumulator plate providing a dead air space which, in turn, is spaced from an insulating wall providing a circulating air space, characterized by the fact that all of the air to be heated is in heat-exchange with the rear surface only of the accumulator plate and by the fact that circulating air never comes into contact with the rear surface of the window. The accumulator plate is 5 millimeters or less in thickness, and is made of an aluminum alloy which, at that thickness, provides an isothermic plate which promotes uniform heat transfer and which has a coefficient of expansion which results in distortion of the surface plane of the plate to provide increased surface exposure, particularly during the early hours of the collection day, when the sun's rays are at less than a 90 degree angle.
