Benefits of technology

[0017]A fifth objective of the present invention is to provide a means for creating spacing and sealing between collector plates which is simple to construct with readily available materials.
[0018]A sixth objective of the present invention is to provide

Problems solved by technology

The convective losses are affected by the insulating bed and air envelopes, and the reflective losses depend on the reflectivity of facing surfaces, including the transparent covering.
Since the water is not in direct contact with the collector plate, some loss of conductive heat efficiency occurs.
Insufficient dwell time in contact with a radiantly heated surface might be a problem with this construction, which problem is overcome by the preferred serpentine path.
Such a construction, additionally, involving welded joints, cannot be taken apart for cleaning

Embodiment Construction

[0041]For the purposes of this description and for the claims following, the term “o-ring” can mean both toroidal and flat-shaped, and connotes compressibility such that sealing is achieved. Similarly, the term “water” is to be construed as meaning any liquid.

[0042]A solar hot water heater 1 is shown in FIGS. 1 and 2. Solar hot water heater 1 is comprised of a frame 2, which houses an absorber panel 10 and a transparent cover 3, which provides an enclosure. The air space 5 within the enclosure and above the absorber panel 10 functions to reduce convective heat losses. Solar radiation 4, passing through the transparent cover 3 and the air space 5, is incident upon the absorber panel 10 where the radiation heats the contents therein by conduction through its absorption. Insulation material may optionally be added between frame 2 and absorber panel 10. Coatings may also be optionally added to both the absorber panel 10 and the transparent cover 3 to respectively enhance absorption and ...

Abstract

A low-cost absorber panel for a solar hot water heating system is provided. An aluminum absorber plate, under exposure to solar radiation, makes an efficient transfer of heat to water circulating within the collector panel by direct contact with the medium in an optimized area-to-volume configuration. An innovative use of fasteners makes it possible to accommodate expansion for freezing and to allow for disassembly and maintenance. Additionally, a low-cost heat exchanger and a low-cost solar hot water system are presented using common structures.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This is a Continuation-in-Part of U.S. patent application Ser. No. 12 / 335,577, filed Dec. 16, 2008, and to which priority is herein claimed.FIELD OF THE INVENTION[0002]The invention relates to solar energy collectors, and more specifically to low pressure solar hot water heater absorbers.BACKGROUND OF THE INVENTION[0003]With the potential of future capacity shortages in the aging infrastructure of the electricity grid in the United States, not to mention the adverse-weather-prone supply of natural gas in the nation, solar energy represents an alternative to looming energy crisis's, as well as rising energy costs in the present. Next to space heating, water heating is the most significant factor in residential energy consumption and accounts for 13% of the household energy bill. What is needed is a solar hot water heating installation that can be accomplished on a budget by the average homeowner.[0004]Flat-plate solar collectors for water ...
