Abstract
A molded plastic base has longitudinally extended channels, with the channel walls being relieved at laterally spaced locations to define closely spaced posts which support a transparent cover. A flat metal heat absorbing plate is provided just below the cover, and has holes for loosely receiving the posts. A corrugated plate is welded to the underside of the heat absorbing plate to define fluid passageways, which passageways are located in the channels of the base. The plate assembly is supported at one end of the base by inlet and outlet pipes for circulation fluid to be heated, and at the opposite end the plate assembly is supported by a gas adsorbing device which operates from the expansion and contraction of the plate assembly in order to preserve the vacuum in the area surrounding the heat absorbing plate.
Claims17
A solar heat collector panel comprising:
- a. a base defining an upwardly open cavity with a floor,
- b. a cover for closing said base cavity to allow evacuating of said cavity,
- c. a flat heat collector plate in said base cavity and spaced downwardly below the underside of said cover,
- d. means defining longitudinally extending fluid passageways in said plate,
- e. means supporting said plate including at least one plate support member mounted in said base, and a member adapted to cooperate with said plate support member and carried by the underside of said collector plate, one of said members being made from a gas sorptive material, the other of said members engaging said gas sorptive member to abrade it in response to movement of said collector plate relative to said base due to thermal expansion and contraction of said plate caused by variations in the incident solar energy.
A solar heat collector panel comprising a base defining an upwardly open cavity with a floor, a plurality of longitudinally and laterally spaced posts projecting upwardly into said cavity from said base, a cover for closing said base cavity to allow evacuating said cavity, said cover being supported on said posts, a flat heat collector plate in said base cavity and spaced downwardly below the underside of said cover, said plate having a plurality of openings for loosely receiving said posts, means carried by the underside of said plate and defining longitudinally extending fluid passageways, and means supporting said plate and said passageway defining means in spaced relationship above the floor of said base cavity, means supporting said plate including at least one plate support member mounted in said base, and a member adapted to cooperate with said plate support member and carried by the underside of said collector plate, one of said members being made from a gas sorptive material, the other of said members engaging said gas sorptive member to abrade it in response to movement of said collector plate relative to said base due to thermal expansion and contraction of said plate caused by variations in the incident solar energy.
A solar heat collector panel comprising a base defining an upwardly open cavity with a floor, a plurality of longitudinally and laterally spaced posts projecting upwardly into said cavity from said base, a cover for closing said base cavity to allow evacuating said cavity, said cover being supported on said posts, a flat heat collector plate in said base cavity and spaced downwardly below the underside of said cover, said plate having a plurality of openings for loosely receiving said posts, means carried by the underside of said plate and defining longitudinally extending fluid passageways, and means supporting said plate and said passageway defining means in spaced relationship above the floor of said base cavity, said base defines a plurality of side-by-side longitudinally extending channels, each channel defining a longitudinally extending cavity for at least one of said fluid passageways, and each channel having side walls which define said posts.
