Abstract

Abstract An improved solar water heater construction is diclosed wherein unique intake and exhaust manifold structures are utilized to control the flow of water through a plurality of heater panels. By virtue of the construction of the manifolds and their cooperation with the heater panels, normal valving systems are not necessary to the maintenance of a uniform, balanced flow of water through the improved heater of this invention.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 286 words
An improved solar heater of the type primarily intended for use in heating water; comprising in combination: a plurality of heater panel means including substantially identical length water flow channeling means formed therein, each of said plurality of heater panel means comprising an intake orifice formed at one end of said water flow channeling means and an exhaust orifice formed at the other end of said water flow channeling means whereby water may enter said intake orifice and travel through said water flow channeling means and exit from said exhaust orifice; intake manifold means including a main intake conduit disposed in fluid communicating relation to a water supply, said intake manifold means further including a pair of substantially oppositely extending supply branches formed thereon and communicating with said main intake conduit, said intake manifold means including a plurality of supply heads formed on said supply branches, a first plurality of water conduits disposed in interconnecting relationship between said plurality of supply heads and said intake orifices of said plurality of heater panel means; exhaust manifold means including a main exhaust conduit comprising a pair of substantially oppositely extending exhaust branches formed thereon and communicating with said main exhaust conduit, said exhaust manifold means including a plurality of exhaust heads formed on said exhaust branches, a second plurality of water conduits disposed in interconnecting relationship between said plurality of exhaust heads and said exhaust orifices of said plurality of heater panel means, and means establishing the sum of the longitudinal dimensions of each pair of said first and second water conduits to be substantially identical throughout said solar heater to provide a balanced flow of water through said heater panel means without the use of mechanical valves.
Claim 2
Dependent Claim 286 words
An improved solar heater of the type primarily intended for use in heating water; comprising in combination: a plurality of heater panel means including substantially identical length water flow channeling means formed therein, each of said plurality of heater panel means comprising an intake orifice formed at one end of said water flow channeling means and an exhaust orifice formed at the other end of said water flow channeling means whereby water may enter said intake orifice and travel through said water flow channeling means and exit from said exhaust orifice; intake manifold means including a main intake conduit disposed in fluid communicating relation to a water supply, said intake manifold means further including a pair of substantially oppositely extending supply branches formed thereon and communicating with said main intake conduit, said intake manifold means including a plurality of supply heads formed on said supply branches, a first plurality of water conduits disposed in interconnecting relationship between said plurality of supply heads and said intake orifices of said plurality of heater panel means; exhaust manifold means including a main exhaust conduit comprising a pair of substantially oppositely extending exhaust branches formed thereon and communicating with said main exhaust conduit, said exhaust manifold means including a plurality of exhaust heads formed on said exhaust branches, a second plurality of water conduits disposed in interconnecting relationship between said plurality of exhaust heads and said exhaust orifices of said plurality of heater panel means, and means establishing the sum of the longitudinal dimensions of each pair of said first and second water conduits to be substantially identical throughout said solar heater to provide a balanced flow of water through said heater panel means without the use of mechanical valves.
Claim 3
Dependent Claim 86 words
An improved solar heater as in claim 1 wherein each of said plurality of heater panel means comprise correspondingly configured top and bottom portions, and wherein said water flow channeling means comprise said top and bottom portions having divider means correspondingly formed thereon in abutting relation to each other when said top portion is placed on said bottom portion, whereby the flow of water through said heater panel means is regulated along a predetermined route, said route being at least partially defined by said divider means.
Claim 4
Dependent Claim 59 words
An improved solar heater as in claim 2 wherein each of said plurality of heater panel means further comprise skirt means disposed in substantially surrounding relation to the sides and base of each of said bottom portions, said skirt means including an insulating material disposed on the interior thereof, whereby solar energy is retained within said heater panel means.
Claim 5
Dependent Claim 41 words
An improved solar heater as in claim 1 further comprising pump means operatively disposed upstream of said intake manifold means, said pump means supplying water to said solar heater at a pressure of from 15 to 100 pounds per square inch.
Claim 6
Dependent Claim 48 words
An improved solar heater as in claim 1 further comprising pressure relief valve means operatively disposed downstream of said exhaust manifold means, said pressure relief valve means being automatically responsive to a predetermined water pressure, whereby excess pressure may be vented to prevent rupture of said solar heater.
Claim 7
Dependent Claim 39 words
An improved solar heater as in claim 1, wherein the sum of the longitudinal dimensions of each water flow path through each of said plurality of heater panel means is substantially identical between said intake and exhaust manifold means.
