ABSTRACT:
The heat of solar radiation is collected through a thin receptor panel directly into liquid held against and flowable upwardly along the panel in shallow channels extending between upper and lower plenum spaces in a receptor chamber which is inclined across the path of the sunlight and connected in a flow circuit kept completely filled with the liquid under a limited constant hydrostatic pressure. The flow circuit extends from the upper plenum space to a heat exchange zone and then back into the lower plenum space. The receptor chamber is formed by two flexible plastic panels which are sealed together peripherially and also along closely spaced longitudinal seams to provide the channels and plenum spaces. The panel seams limit the depth of bulging of the channels and plenum spaces by the pressure of the liquid, and bulging is further constrained and distortion of the receptor prevented by means along the opposite side edges of the chamber which hold the receptor under cross tension counteracting the hydraulic pressure. The volume of liquid filling the receptor is so small in relation to the surface area exposed to radiation that little sun time is lost in bringing the system to a relatively high temperature for delivery of the collected heat.
