Abstract

Abstract ABSTRACT OF THE DISCLOSURE This invention relates to an improved solar heating panel for converting solar energy to thermal energy in a cir-culating fluid to be used for heating or other purposes. A transparent plastic film is secured to a flat dark opaque sur-face to form a channel therebetween for the circulating fluid. The transparent film which faces the sun is uneven shaped whereby some of the sun's rays which strike the solar panel are reflected to an adjacent portion of the panel. For instance, the film may be shaped to form a series of interconnected domes or pyramids, or a number of interconnected semitubular portions. The solar radiation which passes through the transparent film is received by the opaque surface where it is converted to thermal energy in the presence of the carrier fluid. The resulting im-proved efficiency permits smaller solar collectors to be con-structed at a lesser cost, and also eliminates the need to attempt to have the solar panel move to face the sun at right angles as it constantly changes position.

Claims Analysis

Total Claims: 10
Claim 1
Independent Claim 103 words
A solar heating panel having a flow channel through which a fluid flows to be heated by solar energy comprising: (a) a first dark opaque sheet, and (b) a second transparent sheet facing the sun, the second sheet being shaped to form a plurality of interconnected adjacent protruding transparent portions, the first and second sheets being joined together to define the fluid flow channel therebetween which extends through hollow areas formed between the protruding portions of the second sheet and the first sheet, the protruding portions being shaped to reflect a portion of the incident energy from the sun to the adjacent portions.
Claim 2
Dependent Claim 103 words
A solar heating panel having a flow channel through which a fluid flows to be heated by solar energy comprising: (a) a first dark opaque sheet, and (b) a second transparent sheet facing the sun, the second sheet being shaped to form a plurality of interconnected adjacent protruding transparent portions, the first and second sheets being joined together to define the fluid flow channel therebetween which extends through hollow areas formed between the protruding portions of the second sheet and the first sheet, the protruding portions being shaped to reflect a portion of the incident energy from the sun to the adjacent portions.
Claim 3
Dependent Claim 26 words
A solar heating panel as claimed in claim 1 wherein the transparent portions of the second sheet have the shape of a series of interconnected domes.
Claim 4
Dependent Claim 21 words
A solar heating panel as claimed in claim 1 wherein the transparent portions of the second sheet are substantially semitubular shaped.
Claim 5
Dependent Claim 26 words
A solar heating panel as claimed in claim 1 wherein the transparent portions of the second sheet have the shape of a series of interconnected pyramids.
Claim 6
Dependent Claim 18 words
A solar heating panel as claimed in claim 2, 3 or 4 wherein the first sheet is flat.
Claim 7
Dependent Claim 19 words
v A solar heating panel as claimed in claim 2, 3 or 4 wherein the first sheet is black.
Claim 8
Dependent Claim 29 words
A solar heating panel as claimed in claim 2, 3 or 4 wherein the second sheet is formed of a transparent plastic and adhesively secured to the first side.
Claim 9
Dependent Claim 115 words
A solar heating panel having a flow channel through which a fluid flows to be heated by solar energy, the panel having a flat dark opaque surface with a transparent plastic sheet secured thereto, the sheet being shaped to form series of outwardly projecting interconnected domes whereby a portion of the incident energy from the sun is reflected from each dome to an adjacent dome, the dark surface and the transparent sheet thereby defining a continuous liquid flow channel connecting a liquid inlet and a liquid outlet, the panel being oriented whereby a portion of the incident energy from the sun will pass through the transparent sheet and the liquid to strike the opaque surface.
Claim 10
Dependent Claim 115 words
A solar heating panel having a flow channel through which a fluid flows to be heated by solar energy, the panel having a flat dark opaque surface with a transparent plastic sheet secured thereto, the sheet being shaped to form series of outwardly projecting interconnected domes whereby a portion of the incident energy from the sun is reflected from each dome to an adjacent dome, the dark surface and the transparent sheet thereby defining a continuous liquid flow channel connecting a liquid inlet and a liquid outlet, the panel being oriented whereby a portion of the incident energy from the sun will pass through the transparent sheet and the liquid to strike the opaque surface.
