  • Patent number: 9671176
    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). An effective cross-sectional area A of the subspace (71a) in the header-collecting pipe (70) is set based on a mass flow rate of the refrigerant flowing into the subspace (71a) 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).

    Abstract: Abstract: The Re-Corable Coaxial Hose System allows temperature control to be added around material-carrying tubing in both new and existing dispensing systems. The jacketing system seals around the material-carrying tube and allows a thermal transfer fluid to be circulated in the resulting annular space so as to change the temperature of the material being dispensed. Because the system is comprised of a series of tubing and hoses it is flexible and can be routed around corners and through wire tracks and can be used in both manual and robotic applications. Because the seals around the material-carrying tube can be released and subsequently re-sealed, the internal material-carrying tube can be replaced, defined as “re-coring” the hose assembly.

  • Patent number: 8397797
    Abstract: A heat exchanger with multi-flow capabilities includes a pair of intermediate tanks located between a pair of header tanks. An open gap is provided between the two intermediate tanks. A first plurality of tubes extend between the header tanks. A second plurality of tubes extend between one of the header tanks and one of the intermediate tanks. A third plurality of tubes extend between the other header tank and the other intermediate tank. In a two flow system, the two intermediate tanks are in fluid communication through a flexible jumper tube. In a three flow system the two intermediate tanks are isolated from each other. The open gap between the intermediate tanks allows for the uneven heat expansion between the various fluid flows.

  • 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: 8240365
    Abstract: It is known that corrugated plate heat exchangers can have good thermal and hydraulic performance but limitations with regard to operational pressures whilst conventional tube type heat exchangers can achieve high pressure operation but can have high flow pressure losses due to the configuration of such tubes. By arranging a tube stack comprising respective tubes 2a, 3a arranged in layers typically one upon the other with cross junctions 4 between them and intersticial gaps between tubes it is possible to create swirling spinning motion in the flow possibly inside and at least outside the tubes for improved heat exchange with only limited flow restriction. The swirling flow in the heat exchanger matrix outside of the tubes passes along channels formed by the interconnecting intersticial gaps between the tubes and is guided about those tubes for heat exchange.

  • Patent number: 8191615
    Abstract: A heat exchanger apparatus is provided wherein a multifluid or at least three-fluid heat exchanger is mounted externally to but in combination with a two-fluid heat exchanger. The multifluid heat exchanger includes three fluid passages or conduits wherein heat energy can be transferred efficiently between at least one of the fluid conduits and each of the other fluid conduits. The multifluid heat exchanger and two fluid heat exchanger are arranged so that the two heat exchangers share a common fluid, the multifluid heat exchanger, therefore, allowing heat transfer to or from the common fluid to the two other fluids in the multifluid heat exchanger thereby improving the overall heat transfer amongst the fluids.
