    Abstract: A heat exchanger is provided to efficiently transfer heat between air and a flow of refrigerant in a reversing air-sourced heat pump system. When the system is operating in heat pump mode, a flow of air is directed through the heat exchanger and is heated by the refrigerant. A portion of the flow of air is prevented from being heated by the refrigerant in a first section of the heat exchanger, and is used to sub-cool the refrigerant in another section of the heat exchanger after the remaining air has been heated by the refrigerant. The same heat exchanger can be used to cool a flow of air using expanded refrigerant when the system is operating in an air conditioning (cooling) mode.

    Abstract: In a heat exchanger, each of flat tubes (31) has an end portion inserted in a header-collecting pipe (70). When the heat exchanger functions as an evaporator, a refrigerant in a gas-liquid two-phase state upwardly flows in a subspace (71a) located in the header-collecting pipe (70).

The effective cross-sectional area A is obtained by subtracting a projected area A1 which corresponds to a portion of each flat tube (31) located in the subspace (71a) and is projected onto a plane perpendicular to an axial direction of the header-collecting pipe (70) from an area A0 of a cross section of the subspace (71a) which is perpendicular to the axial direction of the header-collecting pipe (70).

  • Patent number: 8429819
    Abstract: Systems and methods for improving heat exchangers by implementing self-energizing seals. In one embodiment, a U-tube heat exchanger includes a shell enclosure, a tube sheet, a closure and a set of tubes welded to the tube sheet. The tube sheet separates first and second chambers from a third chamber in the shell enclosure. The closure seals the first and second chambers. Each tube extends from the first chamber, through the third chamber to the second chamber. The improvement comprises a seal between the shell enclosure and either the closure or the tube sheet. The seal includes conically tapered sealing surfaces on the shell enclosure and closure or tube sheet which form a wedge-shaped gap. A seal ring having surfaces complementary to the sealing surfaces of the shell enclosure and closure or tube sheet is positioned between the sealing surfaces to form a self-energized seal.

  • Patent number: 8256503
    Abstract: A plastic heat exchanger has a shell with tanks disposed side-by-side. First and last distribution tanks straddle heat transfer tanks. The shell has a plurality of flow gaps, to allow coolant to flow between adjacent tanks. Spacers hold the flow gaps open. Upper and lower flanges are adhesively attached to the shell. Flange holes align with the tanks. Each flange hole has an annular wall encircling one of the tanks to preclude the shell from expanding. Upper and lower manifolds are adjacent the flanges, and have chambers disposed side-by-side for each heat transfer tank. Baffles are adapted to be removably received between the chambers to selectively block flow. A plurality of tubes extends between upper and lower tube headers, comprising a tube bundle, removably received within each of the heat transfer tanks. A header O-ring is between each header and flange. A seal plate is disposed against each flange. Each seal plate has seal plate holes in alignment with the flange holes, defining a hole pair.

  • Patent number: 8147797
    Abstract: A system for cooling and recuperative heating of a slurry in a metallurgical process which includes heat exchangers, pumps and autoclaves is described herein. The heat exchangers use a non-scaling common liquid heat transfer medium. Preferably, the heat exchangers are tube-in-tube heat exchangers with 3 to 7 slurry tubes in each heat exchanger. An advantage of this system is that it does not use flash tanks. To minimize abrasive wear on impinged surfaces, the velocity of the slurry is not more than 5 meters per second. The slurry comprises a solids concentration of 25% to 50%. Preferably, the pumps in the system are float-type pumps in which the driven liquid from the discharge pumps is also used as the drive liquid for the feed pumps.
