Solar heat collector
Patent
·
OSTI ID:7080733
A highly efficient solar heat collector is characterized by a layer of light transmitting insulating (i.e., convection and infra-red radiation suppressing) material disposed between the outer surface of the collector and the heat absorptive layer thereof. Glass fibers are a particularly effective lightweight insulating material which may be used. Through use of flexible polymeric films, lightweight, low-cost solar heat collectors may be fabricated for conversion of existing structures to partial or complete solar heating. Either gaseous or liquid heat transfer fluids may be used. A novel gas-liquid heat exchange system is disclosed. 14 claims, 8 figures.
