Abstract
In a solar thermal energy collection system comprising at least one unitary, coextruded solar collector panel, having an upper, heat insulating region, and a lower, heat absorbing region, each region having channels extending longitudinally therethrough, adapted to contain a fluid therein, and a pair of headers, connected to the collector panel along an interface abutting the ends of the channels of the heat insulating region and the heat absorbing region, and connecting the collector panel to the remainder of the collection system, an improved header is provided; having a wall, which extends outward, initially tangentially, from a point along the interface which is substantially closest to the axial center of the header, and then along the interior of the wall of the header, forming a transitional channel which communicates with the second channels and which uniformly directs a fluid between the second channels and the central cavity defined by the header; and having an inner and outer wall, separating the cavity of the header from its exterior, and a plurality of ribs separating the inner and outer wall from each other, to form longitudinally extending channels which serve as heat insulating channels between the exterior of the header and the fluid circulating therein.
