Abstract

Solar heat energy collectors of the gaseous heat exchange type where the absorber is in the form of a duct completely out of thermal contact with the collector housing and extending between openings in opposite sides of the housing. Resilient seals are provided about the housing openings and compressively engaged with each other to prevent egress of heated gas or ingress of ambient air.
