Abstract
Abstract Solar heat energy collectors of the gaseous heat exchange type where the absorber is in the form of a duct completely out of thermal contact with the collector housing and extending between openings in opposite sides of the housing. Resilient seals are provided about the housing openings and compressively engaged with each other to prevent egress of heated gas or ingress of ambient air.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
163 words
In a solar collector of the air heat exchange type including a housing member in which the air passes through a duct whose upper surface is an absorber, and where the air passes from one collector to another, the improvement comprising means defining an air duct in said housing out of thermal conductive contact with said housing, said housing having openings in at least one side wall thereof, said duct extending between said housing openings with the ends of the duct very close to but out of contact with the edges defining said openings, the ends of said duct being aligned with said openings, a thermally insulating resilient sealing member surrounding said openings at the edges thereof and secured to said housing, whereby when two of said collectors are joined with the openings aligned, said sealing means compressively and resiliently engages and provides an air seal about said openings and ducts in said housings are aligned and in direct communication across said openings.
Claim 2
Dependent Claim
163 words
In a solar collector of the air heat exchange type including a housing member in which the air passes through a duct whose upper surface is an absorber, and where the air passes from one collector to another, the improvement comprising means defining an air duct in said housing out of thermal conductive contact with said housing, said housing having openings in at least one side wall thereof, said duct extending between said housing openings with the ends of the duct very close to but out of contact with the edges defining said openings, the ends of said duct being aligned with said openings, a thermally insulating resilient sealing member surrounding said openings at the edges thereof and secured to said housing, whereby when two of said collectors are joined with the openings aligned, said sealing means compressively and resiliently engages and provides an air seal about said openings and ducts in said housings are aligned and in direct communication across said openings.
Claim 3
Dependent Claim
32 words
A system embodying at least two collectors as defined in claim 1 and further including means for holding adjacent collectors in spaced relation with the seals of adjacent collectors in compressive engagement.
Claim 4
Dependent Claim
30 words
The collector of claim 1 where the frame of said housing is formed with interlocks and said sealing member is provided with a locking tab releasably locked in said interlocks.
Claim 5
Dependent Claim
21 words
The collector of claim 1 wherein said sealing members are adhered to said collector housing at the edges of said openings.
Claim 6
Dependent Claim
21 words
The collector of claim 1 wherein said sealing members are of a closed cell construction and define an internal channel therethrough.
Claim 7
Dependent Claim
21 words
The collector of claim 1 wherein said sealing members are configured to have plural areas of contact along the lengths thereof.
Claim 8
Dependent Claim
35 words
The collector of claim 1 wherein said sealing member has an extension thereon extending through the opening in the collector and overlying said duct to thermally insulate the housing from air flow through the duct.
Claim 9
Dependent Claim
33 words
The collector of claim 1 where the frame of said housing is formed with protruding tabs about said openings, and said sealing members are provided with a locking tab releasably receiving said tabs.
Claim 10
Dependent Claim
21 words
The collector of claim 8 where said sealing members are adhered to said collector housing at the edges of said openings.
Claim 11
Dependent Claim
113 words
An array of solar collectors comprising at least two adjacent collectors having housings with absorbers therein, said absorbers being in the form of a duct where airflow passes beneath the absorber, openings defined in adjacent walls of said housings and aligned with said ducts, said ducts extending very close to said openings but out of contact with said housings, resilient sealing members surrounding said openings at the edges thereof and secured to said housings, said housings being positioned together with the adjacent openings aligned and the ends of said ducts aligned, said sealing means on each of said housings being in compressive engagement and providing a seal about the openings in said collectors.
Claim 12
Dependent Claim
113 words
An array of solar collectors comprising at least two adjacent collectors having housings with absorbers therein, said absorbers being in the form of a duct where airflow passes beneath the absorber, openings defined in adjacent walls of said housings and aligned with said ducts, said ducts extending very close to said openings but out of contact with said housings, resilient sealing members surrounding said openings at the edges thereof and secured to said housings, said housings being positioned together with the adjacent openings aligned and the ends of said ducts aligned, said sealing means on each of said housings being in compressive engagement and providing a seal about the openings in said collectors.
Claim 13
Dependent Claim
33 words
The collectors of claim 10 where the frame of said housings are formed with interlocks and each sealing member is provided with a locking tab releasably locked in said interlocks of a frame.
Claim 14
Dependent Claim
21 words
The collectors of claim 10 wherein said sealing members are adhered to said collector housing at the edges of said openings.
Claim 15
Dependent Claim
21 words
The collectors of claim 10 wherein said sealing members are of a closed cell construction and define an internal channel therethrough.
Claim 16
Dependent Claim
21 words
The collector of claim 10 wherein said sealing members are configured to have plural areas of contact along the lengths thereof.
Claim 17
Dependent Claim
34 words
The collector of claim 10 wherein said sealing members have an extension thereon extending through the opening in the collector and overlying said duct to thermally insulate the housing from airflow through the duct.
Claim 18
Dependent Claim
33 words
The collectors of claim 1 where the frames of said housings are formed with protruding tabs about said openings, and said sealing members are provided with a locking tab releasably receiving said tabs.
