ABSTRACT:
A flat plate hydronic solar collector combining features of both the trickle and pressurized type of collector and also of metal and plastic collectors, the invention consisting of a plastic film tube divided into pockets into which heat transfer liquid flows by gravity, moving through a multiple number of pockets as the liquid progresses through the tube, removing heat from the side of the tube facing the sun, the pressure in each pocket being limited by the depth of the pocket. An important embodiment of the invention has a metal solar energy absorber plate secured over the film tube and its mounting surface so that the swelling of the film tube causes it to make extensive contact with the metal absorber.
