Abstract
Abstract A heat exchanger having a desired system of tubular passageways for a heat exchange medium defining opposed headers connected by connecting portions of said passageways extending therebetween, said passageways having entry and exit portions extending from said headers to provide ingress and egress openings for said heat exchange medium, wherein said headers include a fluid distributing pattern comprising at least one bonded portion defining at least one wedge-shaped projection, said projection provided to assist in the distribution of flow of said heat exchange medium.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
170 words
A metal panel for use in a solar energy collector system having a desired system of internal tubular passageways for a heat exchange medium disposed between spaced apart portions of the thickness of said panel and defining opposed headers connected by a plurality of spaced, parallel individual connecting portions of said passageways extending therebetween, with at least one first bonded portion of said metal defining said connecting portions, said passageways having entry and exit portions extending from said headers to opposed edges of said panel to provide ingress and egress openings for said heat exchange medium, wherein said headers each include a fluid distributing pattern comprising at least one second bonded portion, of said metal in said headers spaced from said first bonded portion, each of said second bonded portions defining at least one wedge-shaped projection adjacent and in juxtaposition to said entry and exit portions, respectively, said projections provided to assist in the distribution of flow of said heat exchange medium and to subdivide said flow into discrete channels.
Claim 2
Dependent Claim
170 words
A metal panel for use in a solar energy collector system having a desired system of internal tubular passageways for a heat exchange medium disposed between spaced apart portions of the thickness of said panel and defining opposed headers connected by a plurality of spaced, parallel individual connecting portions of said passageways extending therebetween, with at least one first bonded portion of said metal defining said connecting portions, said passageways having entry and exit portions extending from said headers to opposed edges of said panel to provide ingress and egress openings for said heat exchange medium, wherein said headers each include a fluid distributing pattern comprising at least one second bonded portion, of said metal in said headers spaced from said first bonded portion, each of said second bonded portions defining at least one wedge-shaped projection adjacent and in juxtaposition to said entry and exit portions, respectively, said projections provided to assist in the distribution of flow of said heat exchange medium and to subdivide said flow into discrete channels.
Claim 3
Dependent Claim
22 words
The panel of claim 1 wherein said entry portion and said exit portion extend from the opposite sides of respective opposed headers.
Claim 4
Dependent Claim
77 words
The panel of claim 1 wherein each of said entry and exit portions has a central axis, and said headers possess outer boundaries defining the perimeter thereof, and at least one of said boundaries lying adjacent the apex of said perimeter defines an external angle of at least 91° with respect to the central axis of the adjacent entry or exit portion with which it intersects, and said angle is taken in the plane containing said panel.
Claim 5
Dependent Claim
13 words
The panel of claim 3 wherein said angle ranges from 92° to 100°.
Claim 6
Dependent Claim
16 words
The panel of claim 1 wherein said pattern comprises a plurality of said second bonded portions.
Claim 7
Dependent Claim
18 words
The panel of claim 5 wherein a plurality of wedge-shaped projections are defined by said second bonded portions.
Claim 8
Dependent Claim
16 words
The panel of claim 6 wherein said second bonded portions are provided in a cascading arrangement.
