Abstract
Abstract A solar heater for heating water passing therethrough. The heater includes a corrugated radiant-heat absorbing panel slanted parallel to the corrugations, a liquid-delivery manifold-pipe along the upper end of the corrugated panel and having discharge apertures in operative registration with the upper ends of the upwardly-facing troughs of such corrugations, and a slotted envelope-protector and liquid-discharge pipe extending across and mounted to the lower edge-zone of the corrugated panel, with the lower edge-zone thereof extending into and tightly fitted in the slot of the pipe;-- the upper liquid-supply manifold-pipe and the lower liquid-discharge pipe and the corrugated panel therebetween being fully enveloped by and sealed within a flexible envelope formed of pliable weather-resistant plastic sheeting, at least the top panel of which envelope is highly transparent.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
165 words
A solar heater including an inclined corrugated radiant-heat-absorbing panel, with the troughs of the corrugations extending between the upper and lower edge-zones of the panel, a liquid-supply pipe affixed to the upper edge-zone of the corrugated panel and having orifices therein in registration with the upwardly-facing open ends of the troughs of the corrugated panel, a liquid-discharge pipe extending along and affixed to the lower edge zone of the corrugated panel and communicating with the troughs thereof, and a flexible plastic envelope enveloping said pipes and the corrugated panel therebetween, including an upper and a lower plastic panel, of which at least the upper one is transparent, said envelope having the bottom, side and top marginal zones of its two panels sealed to each other and having a sleeve at the inlet thereof through which the supply pipe extends and to which it is sealed and having a sleeve at the outlet thereof through which the discharge pipe extends and to which it is sealed.
Claim 2
Dependent Claim
165 words
A solar heater including an inclined corrugated radiant-heat-absorbing panel, with the troughs of the corrugations extending between the upper and lower edge-zones of the panel, a liquid-supply pipe affixed to the upper edge-zone of the corrugated panel and having orifices therein in registration with the upwardly-facing open ends of the troughs of the corrugated panel, a liquid-discharge pipe extending along and affixed to the lower edge zone of the corrugated panel and communicating with the troughs thereof, and a flexible plastic envelope enveloping said pipes and the corrugated panel therebetween, including an upper and a lower plastic panel, of which at least the upper one is transparent, said envelope having the bottom, side and top marginal zones of its two panels sealed to each other and having a sleeve at the inlet thereof through which the supply pipe extends and to which it is sealed and having a sleeve at the outlet thereof through which the discharge pipe extends and to which it is sealed.
Claim 3
Dependent Claim
26 words
A solar heater according to claim 1, in which the discharge pipe is slotted and into which slot the lower edge-zone of the corrugated panel extends.
Claim 4
Dependent Claim
32 words
A solar heater according to claim 1, including anchoring means extending from the envelope and arranged to be fastened to the roof or other support on which the solar heater is mounted.
Claim 5
Dependent Claim
41 words
A solar heater according to claim 1, in which the supply pipe is secured to the upper edge-zone of corrugated panel by straps encircling the supply pipe and having extensions flanking upper portions of the panel and secured thereto by screws.
Claim 6
Dependent Claim
43 words
A solar heater according to claim 1, in which the plastic envelope folds around and in contact with the outermost portion of the surface of the upper pipe which is bisected by the plane in which the axes of the two pipes lie.
Claim 7
Dependent Claim
45 words
A solar heater according to claim 1, in which the plastic envelope folds around and in contact with the outermost portions of the surfaces of the upper and lower pipes which are bisected by the plane in which the axes of the two pipes lie.
