Abstract
In a solar heat collector. A shallow hollow member. A transparent cover for said member. A plurality of load bearing partitions in said hollow member. A plurality of heat collecting plates are spaced between said partitions. A plurality of water pipes are each connected along one of said collector plates and the water pipes are connected in parallel. Inlet and outlet water pipes means are connected to the parallel connected pipes. The outlet pipe connection has an expansion loop to compensate for temperature variations. Vacuum is applied to the hollow member. The partitions are proportioned and spaced so as to support the cover against external atmospheric pressure. Conduction and convection losses from said heat collector plates are minimized because of the vacuum.
