  • Patent number: 8096295
    Abstract: A solar panel includes an inlet manifold, an outlet manifold spaced apart from the inlet manifold, and a plurality of pipes having a first end in open fluid communication with the inlet manifold and a second end in open fluid communication with the outlet manifold. A box-shaped cover formed of a polycarbonate material is disposed in ensleeving relation to the plurality of pipes. The box-shaped cover has a length at least slightly less than the distance between the inlet and outlet manifolds so that opposite ends of pipes in the plurality of pipes are exposed to ambient. The cover substantially prevents ventilation of the plurality of pipes and thus allows water temperatures in the panel to rise higher than possible in the absence of such cover. The exposure of the opposite ends of the pipes to ambient prevents water temperatures in the panel from exceeding a predetermined temperature.

  • Patent number: 8091618
    Abstract: An exchange apparatus comprised of hollow perfluorinated thermoplastic tubes fusion bonded into a perfluorinated thermoplastic material to form unified terminal end blocks is disclosed. The hollow tubes are shaped by plaiting the tubes into cords and thermally annealing the cords to set the bends of the plait. The apparatus can have a housing bonded to the unified terminal end blocks. In use a first fluid enters the hollow tubes at openings in a first unified terminal end block, flows through the lumens of the tubes, and exits the tubes through a second unified terminal end block. A second fluid enters the housing, is separated from the first fluid by the wall of the tubes, and substantially fills the space between the inner wall of the housing and the outer diameters of the hollow tubes. Energy is transferred between the first and second fluids through the tube walls.

  • Patent number: 8025095
    Abstract: Disclosed is a heat exchanger, particularly an exhaust gas heat exchanger for an internal combustion engine of a motor vehicle, comprising a housing jacket that is open at both ends, and a tube bundle which is inserted into said housing jacket and is penetrated by the hot exhaust gas. The aim of the invention is to produce said heat exchanger in an inexpensive and functionally safe manner. Said aim is achieved by the fact that only the tube bundle with the tube bottoms thereof, which are located on the front side, are made of metal while the housing jacket into which the tube bundle is inserted along with the tube bottoms is made of plastic.

  • Patent number: 7749613
    Abstract: A multi-layer aluminum brazing sheet including a core layer, interliner, braze clad layer and a sacrificial layer, in which the post-braze strength of the brazing sheet is optimized by controlling the manganese (Mn), silicon (Si), copper (Cu) and magnesium (Mg) contents of the core layer and the Mn, Si and Cu content of the interliner and the Mn, Si and Zn content of the sacrificial layer and the specifics of the braze thermal cycle. The brazing sheet maintains corrosion resistance, while optimizing post-braze strength, by utilizing 0.5 wt. % to 1.2 wt. % Cu in the interliner. Further, the interliner and sacrificial layer of the brazing sheet contain low or no magnesium to maintain the brazing sheet's braze-ability.
