Abstract
Longitudinally spaced sections of a collapsible plastic tube are supported on vertically spaced support surfaces. The supported sections of the tube serve as liquid reservoirs, these reservoir sections being laterally supported at their outlet ends by an overflow support. When the depth of liquid exceeds the height of the overflow support, the liquid flows downwardly through an overflow section of the tube into the succeeding reservoir section. Air is heated or cooled by flowing it through spaces which are bounded by the reservoir sections. A solar collector has its inlet connected to the lowermost reservoir section, and its outlet connected to the uppermost reservoir section.
Claims11
Apparatus for containing, storing and providing heat exchange with a body of liquid comprising,
- a continuous tube which includes a plurality of vertically spaced reservoir sections for containing quantities of a primary liquid to be heated or cooled, each said reservoir section having at its opposite ends an inlet end and an outlet end,
- liquid passages connecting said reservoir sections and extending downwardly from the outlet end of each reservoir section to the inlet end of a lower said reservoir section,
- an overflow member at the upper end of each of said liquid passages for releasing liquid which exceeds the height of said overflow member into the liquid passage,
- barrier means in intimate contact with and conformable to the upper surface of liquid in each of said reservoir sections, and,
- means for flowing a gaseous medium laterally across said barrier means to remove heat from or add heat to the liquid in said reservoir sections.
Apparatus for containing, storing and providing heat exchange with a body of liquid comprising,
- a plurality of support members having supporting surfaces disposed at different elevations,
- a continuous flexible tube having spaced longitudinal reservoir sections which lie on said plurality of support members,
- said reservoir sections being connected together by vertical overflow sections which extend downwardly from one reservoir section to a said reservoir section therebelow,
- an upper one of said reservoir sections having a liquid inlet means, and a lower one of said reservoir sections having a liquid outlet means,
- an overflow support member at the upper end of each of said vertical overflow sections, said overflow support member being located at an elevation which is higher than its respective supporting surface so the reservoir section does not release liquid until the depth of liquid therein exceeds the height of said overflow support member,
- each of said reservoir sections having an open space thereabove, and means for flowing air through said open space in heat exchange relation to the liquid contained in the reservoir sections.
Apparatus for collecting solar energy, storing the collected energy and providing heat exchange of the stored energy, comprising,
- a solar collector means for heating a liquid, said solar collector means having a collector inlet and a collector outlet,
- a plurality of support members having supporting surfaces disposed at different elevations,
- a continuous flexible tube having spaced longitudinal reservoir sections thereof lying on said plurality of support members, said spaced longitudinal reservoir sections being connected together by vertical overflow sections which extend downwardly from one reservoir section to a said reservoir section therebelow,
- means connecting an upper one of said reservoir sections to the liquid outlet means of the solar collector means,
- means connecting a lower one of said reservoir sections to said liquid inlet means of the solar collector means,
- an overflow support member at the upper end of each of said vertical overflow sections, said overflow support member being located at an elevation which is higher than its respective supporting surface so the reservoir section does not release liquid until the depth of liquid therein exceeds the height of said overflow support member,
- each of said reservoir means having an open space thereabove, and means for flowing air through said open space in heat exchange relation to the reservoir sections and the liquid contained therein.
