Solar heat collecting apparatus

摘要

A combined solar heating apparatus for heating air or water or both air and water comprising a corrugated collector plate with S-shaped tubing traversing the enclosure beneath the plate. The rear of the corrugated plate is enclosed so as to allow filling of the air space with an aggregate material to provide increasing temperature and heat storage characteristics. A continuous tubing with a liquid source is formed with a plurality of S-shaped loops passing through the rear of the collector plate and through the aggregate. A rear wall member is attached to the back of the corrugated collector to form an air enclosure. A transparent plate sealingly encloses the top of the collector, providing an air space between the collector plate and the transparent cover.
