Abstract
A lightweight flat plate heat exchanger comprised of two or more essentially parallel flat plates which are formed and arranged to provide fluid flow passages between the plates. New combinations of plastic plates include the usage of transparent plastic foam and honeycomb structures. Improved shapes of flow passages include the usage of flow nozzles, flow diffusers, and jet pumps to increase fluid flow and heat transfer. The invention includes the usage of transparent plastic foam plates which are shaped to concentrate solar energy onto plastic tubes. Clear plastic tubes containing black heat transfer fluid are included. The invention includes the usage of spiral flow channels within plastic foam plates. Six different embodiments of the invention are included. Five of the embodiments could be used as efficient lightweight solar collectors.
