Abstract
Abstract The invention relates to a support for at least one photovoltaic cell, comprising at least one block made of heat-conducting material with which said cell is in close thermal contact. According to the invention, this support comprises at least one tube the wall of which may be traversed by the heat, said tube being fastened to said block, in thermal contact therewith, and closed at its end to define a closed cavity inside which an evaporable and condensable fluid is enclosed. The invention is particularly applicable to a solar generator.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
54 words
A solar energy collecting device comprising: a plurality of photovoltaic cells; a plurality of heat pipes; said photovoltaic cells being carried by said heat pipes in heat transfer relationship therewith; and a fluid-tight cooling chamber provided with a cold fluid inlet and hot fluid outlet and enclosing at least said plurality of heat pipes.
Claim 2
Dependent Claim
54 words
A solar energy collecting device comprising: a plurality of photovoltaic cells; a plurality of heat pipes; said photovoltaic cells being carried by said heat pipes in heat transfer relationship therewith; and a fluid-tight cooling chamber provided with a cold fluid inlet and hot fluid outlet and enclosing at least said plurality of heat pipes.
Claim 3
Dependent Claim
88 words
The device of claim 1, wherein each heat pipe comprises at least one solid block of heat-conducting material on which at least a part of a said photovoltaic cell is fixed so as to be in close thermal contact with said block, and at least one tube whose wall may be traversed by heat generated in said cell, said tube being fastened to said block, in thermal contact therewith and closed at its ends to define a closed cavity inside which is enclosed an evaporable and condensable fluid.
Claim 4
Dependent Claim
27 words
The device of claim 2, wherein said block comprises a recess extended outwardly by said tube, said closed cavity being defined by said recess and said tube.
Claim 5
Dependent Claim
20 words
The device of claim 2, wherein said tube and said photovoltaic cell are disposed on opposite faces of said block.
Claim 6
Dependent Claim
14 words
The device of claim 2, wherein said tube and said block are integrally formed.
Claim 7
Dependent Claim
35 words
The device of claim 1, further comprising: a collector for concentrating solar radiation in a focal plane; and said photovoltaic cells are directed downwardly in said focal plane and with said heat pipes directed upwardly.
Claim 8
Dependent Claim
32 words
The device of claim 6 wherein said cooling chamber is supported by at least one hollow arm rigidly connected to said collector, said arm communicating with said cooling chamber for fluid flow.
