ABSTRACT:
An inexpensive and efficient solar energy collector formed by a thermally-insulated channel covered by a transparent plate assembly to define an elongated passage having an input end into which air is admitted, and an output end from which air is discharged. The channel is divided into a series of stages each having a heat exchange section therein which acts to transfer absorbed heat to the air flowing therethrough, whereby cool air entering the channel is raised in temperature in the course of its passage. The effective surface area of the heat exchange sections increases progressively in the successive stages, so that as the temperature difference between the air and exchange sections is reduced as the air passes through the stages, the area of exchange increases to maintain a rapid rate of heat transfer. To maximize the heat retention in relation to the radiation acceptance in each stage, the transparent cover assembly is formed by plates whose number is stepped up from the input to the output stage.
