Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
124 words
A receiver for concentrated solar radiation designed to heat a substantially transparent fluid, comprising a tube permeable to solar light radiation, an elongated body capable of absorbing solar radiation disposed within said tube, said body including a series of vanes depending from a common axis, said vanes being disposed about said common axis in a star-like configuration, with inner edges thereof substantially adjacent to each other, so that adjoining vanes are separated by an angle of not more than 72°, and said body having an outer surface area at least twice as great as the inner surface area of said tube, so that light radiation impinging on the outer surface thereof is being repeatedly reflected by the surface thereof for substantially complete absorption thereby.
Claim 2
Dependent Claim
124 words
A receiver for concentrated solar radiation designed to heat a substantially transparent fluid, comprising a tube permeable to solar light radiation, an elongated body capable of absorbing solar radiation disposed within said tube, said body including a series of vanes depending from a common axis, said vanes being disposed about said common axis in a star-like configuration, with inner edges thereof substantially adjacent to each other, so that adjoining vanes are separated by an angle of not more than 72°, and said body having an outer surface area at least twice as great as the inner surface area of said tube, so that light radiation impinging on the outer surface thereof is being repeatedly reflected by the surface thereof for substantially complete absorption thereby.
Claim 3
Dependent Claim
16 words
The receiver according to claim 1, in which the peripheral area of said vanes is corrugated.
Claim 4
Dependent Claim
30 words
The receiver according to claim 1, in combination with a plurality of such receivers, said receivers reduced in size and arranged in a star-shaped configuration for construction of high-power installations.
Claim 5
Dependent Claim
33 words
The receiver of claim 1 in which said tube has an inner wall spaced from said body and said space between said inner wall and said body forms a space for said fluid.
Claim 6
Dependent Claim
17 words
The receiver according to claim 1 in which said body has at least eight radially extending fins.
Claim 7
Dependent Claim
22 words
The receiver according to claim 1 in which said body has a longitudinal bore in the center thereof for conveying said fluid.
