Portable light-weight solar heater
| Details |
Inventors: McColgan, John M.; O'Brien, Philip F.;
Assignee:
Primary Examiner: Sprague; Kenneth W.
Assistant Examiner:
Attorney, Agent or Firm:
A unique and extremely practical solar heater has been described which is particularly suited to the heating of swimming pools. The novelty of the system lies in the use of an extremely light-weight flexible unit of essentially all plastics construction which floats upon the surface of the pool and is easily removed therefrom, and which functions dually as a flat plate collector by virtue of water circulating through it during sunlight hours, and as an efficient insulator and vapor barrier for the pool surface. A number of such units are generally employed to cover most of the surface of a swimming pool, and are covered by a relatively thin plastic over-cover, preferably transparent and tinted an attractive color. |
|
DETAILED DESCRIPTION We claim: 1.
A flat plate solar energy collector assembly adapted to float on the water surface of a pool, comprising a relatively thin flexible cellular plastic sheet floating upon and insulating the surface of the pool, a plurality of parallel flexible thin plastic tubes extending over substantially the entire area of the floating plastic sheet, means securing said tubes to the top surface of the floating sheet, entry means provided at one end of said tubes, exit means provided at the other end of said tubes, said exit means from said tubes being relatively large in comparison to the entry means for said tubes and means for pumping the pool water into said entry means and through said thin flexible plastic tubes during hours of exposure to sunlight.
2.
The flat plate solar energy collector assembly of claim 1, comprising a thin flexible plastic cover means disposed over said collector assembly.
3.
The flat plate energy collector assembly of claim 1, comprising a thin relatively transparent flexible plastic cover means disposed over said collector assembly.
4.
The flat plate solar energy collector assembly of claim 1, wherein a secondary manifold, means connecting said secondary manifold to the entry means of said tubes, means securing said secondary manifold to the floating cellular plastic sheet, a primary manifold and quick-disconnect fitting means interconnecting said secondary manifold and said primary manifold to facilitate quick and easy removal of the solar energy collector assembly from the pool.
5.
The flat plate solar energy collector assembly of claim 4, comprising a thin relatively transparent flexible plastic cover means disposed over said collector assembly.
6.
The flat plate solar energy collector assembly of 1, wherein said exit means discharge directly into said pool.
Description:
BACKGROUND OF THE INVENTION This invention relates to solar water heating systems specifically designed for swimming pools and the like, and provides a novel concept of design featuring light weight and easy removability from the surface of a pool, which tremendously reduces the problems of cost, space and aesthetics which have been serious detriments to more widespread use of solar heaters for swimming pools
