Abstract
The invention disclosed is a solar energy collector apparatus having several double-wall glass tubular elements connected on opposite sides of an elongated manifold to form a module. The elements are sealed in oppositely facing metal cups and inside the opposite elements is a cross supply tube. The cups in a module are series connected by conduits for flow of a liquid through the collectors. Along the manifold are two header pipes respectively connected to the cups for introducing liquid to the collectors for series flow and for receiving heated liquid flowed through them. The headers also connect a series of modules and the system utilizing the solar heated liquid. The cups, header pipes and interconnecting conduits are enclosed in an insulation jacket of foamed plastic, e.g. polyurethane. The manifold includes support brackets for mounting the apparatus in spaced drainage position above a supporting surface having a solar exposure. The outer ends of the tubular collectors are supported on an end loading device which firmly supports the element above the support surface and retains the element in its manifold cup when under hydraulic pressure.
