Abstract: A solar collector including an absorber having at least one channel for conducting a fluid receiving the heat absorbed, a housing enclosing the absorber and having radiation-transparent windows covering and spaced from both faces of the absorber, and partition members disposed between the absorber and the housing and effective to block the circulation of air flowing in the space between one face of the absorber and the housing from flowing to the space between the other face of the absorber and the housing, to thereby reduce convection losses from the absorber.

Abstract: The arrangement for cooling the bottom of a blast furnace comprises cooling plates mounted between the furnace lining and shell and forming vertical and horizontal rows. Each cooling plate incorporates coil pipes situated in two planes parallel to the furnace shell, the coil pipes being connected to each other in vertical rows. There are at least two coil pipes in one of the vertical planes in each plate. Such coil pipes in the plates mounted in the uppermost horizontal row are connected to coil pipes mounted in the top portion of the furnace in two different vertical planes. At least one coil pipe is situated in the other vertical plane in each cooling plate. The coil pipes in the plates mounted in the lowermost horizontal row are controllably connected to cooling medium feed collectors of the furnace common cooling system and to a high-pressure cooling medium source.

Abstract: A solar heating system includes a solar collector comprising a continuous length of copper tubing coiled into a helical array of closely adjacent turns and supported within a sealed housing. The outer turns of the array are fabricated of tubing having a greater diameter than the tubing which forms the inner turns of the array, and the total length of the larger diameter tubing in the array is greater than that of the smaller diameter tubing. The relationships beween the tubing diameters and lengths are selected to achieve a desired flow rate and temperature rise for the overall array. The array is supported within the housing by copper sheets which also operate to eliminate moisture condensation within the housing.

Abstract: A heat collector and radiator for allowing the absorption of lower atmosphere radiation by the maximizing of the surface area capable of absorbing the diffuse radiation. A plurality of closely spaced tubular elements are disposed in parallelism with relatively narrow web portions interconnecting the adjacent tubular elements and in tangential relationship therewith. The structure is unitarily formed from a polymer material admixed with carbon black or like additive. A header means at each opposite end of the tubular elements/web portions communicates therewith. The structure is selective in the respect that it has an emissivity lower than absorptivity, and is less effected by the incident angle.

Abstract: A solar heat collector designed to obtain maximum heat from sunlight rays when operational and minimum heat from sunlight rays when non-operational. The solar heat collector contains two sheets of solid material spaced and confronting each other between which a heat transfer liquid flows through a baffle arrangement so as to increase the efficiency for obtaining higher temperatures of the heat transfer liquid.

Abstract: A heat exchanger for central heating in which water to be heated passes through a circular array of parallel tubes. Hot gas passes over the outside of the tubes and heats the water up. Metal wire interlaces the tubes and helps conduction heat from the gas to the water. Preferably the arrangement of tubes and wires is metal coated to further help the heat conduction.

Abstract: A solar collector in the form of a shell having an upper face of heat-conductive material with recesses and a serpentine coil arranged in the recesses and in a snug fit in heat exchanging relation with the heat absorbing material and said coil comprising a tubular length with an inlet and an outlet opening whereby material to be heated may be flowed through said coil.

Abstract: The underside of the bottom wall of an electric cooker contains a sheathed electric heater element intermittently staked and keyed to the sides and base of a receiving channel to control and confine growth and resist twisting movement of the element therein during heating.

Abstract: Radiator for transmitting heat from a fluid medium to a surrounding atmosphere. The radiator of the invention contemplates rapid and efficient manufacture of radiator units of different sizes from stock material and is arranged for such manufacture either in a factory or at a construction site. Preferably identical top and bottom channeled parts are provided as top and bottom headers of the radiator and extrudable connecting channels are provided for connecting the top and bottom headers. The connecting channels may be cut in any desired length to provide the radiator units of selected sizes and radiating capacity but without change in the manner of connecting the connecting units into and with respect to the top and bottom headers. A variety of ways are shown for effecting such connecting as well as for providing appropriate fluid connections to and from the radiator units.

Abstract: A solar heater has metal pipes arranged in an array connected to carry liquid which will be heated by heat received from solar radiation transmitted through the pipe walls. The pipes are formed from sheet metal so that their internal and external reflectivity may be controlled. The pipes are provided with a dark exterior on the side which will face the sun.

Abstract: The invention provides a solar heating arrangement which has a plurality of substantially hollow elongate members with at least one fluid passage way therein, a plurality of substantially hollow connecting members each adapted to interlock one with the other, each connecting member being adapted so as to interlock with a respective elongate member at each end thereof, the connecting members and the elongate members being interlocked to form a heating arrangement which, when in use, has fluid flowing through it.

Abstract: The solar heat absorber includes a frame and a plurality of clear panels respectively overlying a plurality of arcuate shaped heat collecting plates supported by the frame and compartmented each from the next by separators forming dead air spaces or cells. At least one continuous fluid passage tube is soldered to each plate and provides a cool tube inlet and a feedback hot tube outlet section for each plate whereby some of the heat in the hot tube section is transferred through the cell to its cool tube section within each cell prior to discharge of the fluid out the hot tube section. Each of the cells is at a temperature different than the temperature of an adjacent cell and a heat sink is provided in contact with each panel to substantially equalize the temperature of the panels.

Abstract: A solar heater for heating a fluid passing through a plurality of side by side positioned solar panels. The solar panels are formed of heat conducting material with an upper solar energy exposed surface covered with a radiant heat absorbing material having high heat absorbing characteristics. A conduit formed of heat conducting material is held in place by an open circular channel of a diameter less than the conduit and positioned below the longitudinal center line of the solar panel. The solar panel portions on each side of the center line slopes downward away from the center. The respective ends of the conduits are connected to a separate common header. One header delivers ambient fluid to the conduits and the other removes heated fluid.

The solar panels are formed of heat conducting material with an upper solar energy exposed surface covered with a radiant heat absorbing material with high heat absorbing characteristics. A V shaped hinge groove is positioned along the upper longitudinal center line of the panel. The panel portions on each side of the hinge groove slope downward toward their outer edges.
