Abstract
Abstract A solar collector panel wherein heat absorbed in a collector plate having a broad, uniformly flat surface area may be conducted by a plurality of thermal conductors to a fluid flowing through pipes that are arrayed over the flat surface area of the collector plate. Each of the thermal conductors has broad flat surfaces in contact with the flat surface of the collector plate on opposite sides of the pipe, and an inner surface in mating contact with most of the pipe. The thickness of the thermal conductor increases from the extreme ends of its broad flat surfaces toward its inner surface. The thermal conductors are aluminum extrusions. A thermal joint compound is applied between the thermal conductors and the contacted surfaces of the pipes and the collector plate.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
166 words
A solar collector panel wherein heat absorbed in a collector plate may be conducted to a fluid flowing through pipes that are arrayed over the surface of the plate, comprising a collector plate for absorbing radiant heat; and a plurality of pipes in an array over a surface of the collector plate for transporting a fluid for conducting heat energy from the solar collector panel; wherein the collector plate has a broad uniformly flat surface area over which the pipes are arrayed; characterized by a plurality of thermal conductors for conducting heat energy from the collector plate to the pipes, wherein each of the thermal conductors has broad flat surfaces in contact with the flat surface of the flat collector plate on opposite sides of the pipe, and an inner surface in mating contact with most of the pipe; with the thickness of the thermal conductor increasing from the extreme ends of its broad flat surface toward its inner surface, wherein the thermal conductors are extrusions.
Claim 2
Dependent Claim
166 words
A solar collector panel wherein heat absorbed in a collector plate may be conducted to a fluid flowing through pipes that are arrayed over the surface of the plate, comprising a collector plate for absorbing radiant heat; and a plurality of pipes in an array over a surface of the collector plate for transporting a fluid for conducting heat energy from the solar collector panel; wherein the collector plate has a broad uniformly flat surface area over which the pipes are arrayed; characterized by a plurality of thermal conductors for conducting heat energy from the collector plate to the pipes, wherein each of the thermal conductors has broad flat surfaces in contact with the flat surface of the flat collector plate on opposite sides of the pipe, and an inner surface in mating contact with most of the pipe; with the thickness of the thermal conductor increasing from the extreme ends of its broad flat surface toward its inner surface, wherein the thermal conductors are extrusions.
Claim 3
Dependent Claim
14 words

Claim 5
Dependent Claim
16 words
A solar collector panel according to claim 1, wherein the collector plate is of uniform thickness.
Claim 6
Dependent Claim
40 words
A solar collector panel according to claim 1, further comprising, a thermal joint compound between the thermal conductors and the contacted surfaces of the pipes and the collector plate for filling voids between the thermal conductors and said contacted surfaces.
