  • Patent number: 9534850
    Abstract: A tube bundle heat exchanger has tubes which are held at each side in tube plates or oval-tube collecting-tube plates and are connected to these in each case by means of a weld seam. The connection of the tubes to the inlet-side tube plate or oval-tube collecting-tube plate is formed in each case by means of a conical and/or trumpet-shaped transition piece. The cross section of the transition piece reduces as viewed in the gas flow direction in such a way that the inlet-side end, as viewed in the gas flow direction, of the transition piece is connected in a butt joint to the tube plate or oval-tube collecting-tube plate. The inner and outer contours of the transition piece and of the welded connection region are formed without gaps and corners to the tube plate or oval tube collecting-tube plate and so as to be straight and/or with a radius, measured from the outer contour, of at least 5 mm.

  • Patent number: 9518788
    Abstract: A first header collecting pipe of an outdoor heat exchanger has three communication chambers and one mixing chamber. One auxiliary horizontal partition plate is disposed between two main horizontal partition plates. The mixing chamber is defined between the first main horizontal partition plate and the auxiliary horizontal partition plate. A gas-liquid two-phase refrigerant supplied to the outdoor heat exchanger functioning as an evaporator flows into the mixing chamber, and is then distributed to the three communication chambers. This structure allows the refrigerant that is to be distributed from the mixing chamber to the communication chambers to have a uniform wetness.

  • Patent number: 9366463
    Abstract: A leeward upper header portion of an evaporator includes first through third sections which communicate with upper ends of heat exchange tubes of first through third tube groups of a leeward tube row. The second tube group, which is an upward flow tube group, and the third tube group, which is a downward flow tube group, form a tube group set. A baffle plate is provided in the second section to be located on the side toward the third section. The baffle plate divides a portion of the interior of the second section into upper and lower spaces and prevents flow of refrigerant toward the upper space. A flow prevention member is provided below the baffle plate so as to prevent flow of refrigerant from the second section into the third section. These two sections communicate with each other in a region above the baffle plate.

  • Patent number: 9335076
    Abstract: A distributor assembly for a space conditioning system comprising a sealed expansion device and a sealed distributor housing. The expansion device has a first opening, a second opening and an interior chamber there-between. The interior chamber contains an orifice housing, wherein the orifice housing has a through-hole orifice therein. The orifice housing is configured to move between the first opening and the second opening within the interior chamber. An outer surface of the orifice housing forms a fluid stop around the first opening such that a refrigeration fluid of the space conditioning system delivered through the second opening can substantially only pass through the through-hole orifice to the first opening. The distributor housing has a largest opening that is permanently sealed to the first opening of the sealed expansion device and a plurality of smaller openings configured to be fluidly connected to a heat-exchange coil of the space conditioning system.

  • Patent number: 9151540
    Abstract: The present disclosure is directed to multichannel tubes with flow path inlet sections that allow refrigerant to enter the flow paths through an outer wall of the multichannel tubes. In certain embodiments, a portion of the outer wall is removed to expose the flow paths to a distribution chamber within an inlet manifold divided into an inlet section and a distribution section by a distributor. According to certain embodiments, the inlet section may be designed to have a relatively small cross-sectional area that promotes mixed phase flow of liquid and vapor refrigerant. The multichannel tubes extend into the distribution section to partition the distribution section into a series of distribution chambers defined by a pair of adjacent tubes, the distributor, and the inlet manifold. Within each distribution chamber, the refrigerant may be directed into the multichannel tubes through the flow path inlet sections of the multichannel tubes.

  • Patent number: 9115934
    Abstract: A heat exchanger, such as a radiator, may transfer heat from a liquid and employ a first header tank, a second header tank, a plurality of tubes fluidly joining the first and second header tanks, and a baffle within one of the first or second header tanks. The baffle may be located in a header tank positioned substantially parallel or perpendicular to a surface upon which a vehicle employing the hear exchanger rests. The baffle may be a wall defining only one slot, a wall defining only one slot that is open through one side of the wall, a wall that defines a plurality of slots, or a wall that defines a plurality of holes. The heat exchanger may further employ fluidly isolated first and second tube and fin sections each defining a self-contained flow path for cooling different liquids. The baffle may slow coolant flow in a flow path.
