A modular, air-to-air solar energy collector for adding heat to a circulating flow of air includes a frame-like enclosure and a solar radiation absorbing plate disposed within the frame-like enclosure. The enclosure includes a light-transmissive outer panel, a back panel, an air inlet adjacent a first end and an air outlet adjacent at the same end. A first air flow passageway is defined by the light-transmissive outer panel and the outwardly facing surface of the solar radiation absorbing plate and a second air flow passageway is defined by the inwardly facing surface of the solar radiation absorbing plate and the back panel. A connecting flow aperture at one end of the solar radiation absorbing plate provides flow communication between the first air flow passageway and the second air flow passageway such that entering air passes across the outwardly facing surface of the absorbing plate and is then routed through the connecting flow aperture to the second air flow passageway. The back side of the solar radiation absorbing plate is provided with a plurality of heat-conductive panels which define a maze-like tortuous path through the second air flow passageway such that the entering air is preheated and then routed to the other second air flow passageway where this air absorbs further heat as it passes across both sides of each heat-conductive panel as the air makes its way to the air outlet.

A portable, modular, air-to-air solar energy collector for introducing and adding heat to a circulating flow of air, said solar energy collector comprising: a generally rectangular, free-standing, frame-like enclosure having a back panel, a surrounding side wall, and an enclosing light-transmissive outer panel, the combination of said back panel, said surrounding side wall, and said enclosing light-transmissive outer panel defining an enclosed air space interior thereto; a solar radiation absorbing plate disposed within said frame-like enclosure, said solar radiation absorbing plate having a radiation-facing top surface and a finned bottom surface, and being suitably arranged to segment said enclosed air space into two air flow passageways; an air inlet conduit extending from a location exterior of said frame-like enclosure through said back panel and through said solar radiation absorbing plate, said air inlet conduit being suitably adapted for connection to a source of air at a location exterior of said frame-like enclosure; an air outlet conduit extending from a location exterior of said frame-like enclosure through said back panel, said air outlet conduit being suitably adapted for flow connection to a remote use location for utilization of any exiting air; said solar radiation absorbing plate and said light-transmissive outer panel defining a first air flow passageway across the top surface of said solar radiation absorbing plate, said first air flow passageway having an inlet end in communication with said air inlet conduit and an opposite exit end, said first air flow passageway being free of any intermediate structures which functionally relate to the transfer of heat; and said solar radiation absorbing plate and said back panel defining a second air flow passageway across said bottom surface, said second air flow passageway having an inlet end in communication with the exit end of said first air flow passageway at a location adjacent one end of said frame-like enclosure and an opposite exit end in communication with said air outlet conduit adjacent the opposite end of said frame-like enclosure, said air flow passageways being arranged to provide a continuous, singular flow path from said air inlet conduit to said air outlet conduit.
