A solar collector unit of triangular transverse cross section is provided with a corrugated heat trap element on at least the rear vertical wall of the collector. The heat trap element has a V-shaped cross section, the angle of the V being in the range of about 35°to about 55°. The heat trap element, in part, serves to increase the effective heat transfer surface of the collector at relatively little expense. Additionally, the corrugated member serves as a channel for direction of the flow of fluid to be heated through the collector.

A solar collector unit comprising: a generally triangular housing member including a vertical back wall, a horizontal base, end walls and a sloped light transparent front surface for receiving solar radiation; a corrugated heat trap member defining longitudinally extending tunnels and valleys suspended in front of at least part of said back vertical wall and adapted to receive solar radiation; means for introducing cool air adjacent to horizontal base near said front surface; and means for removing war air from adjacent the vertical back wall near the top thereof whereby at temperatures below about 150°F. air flows through said collector in the direction from said front surface to said vertical back wall and then upwardly through said tunnels and valleys of said heat trap member, and at temperatures above about 150°F. air which would normally flow within the valleys of the heat trap member rises in the collector and moves towards the front surface, thereby rejecting some excess heat to ambient atmosphere.
