  • Patent number: 11060794
    Abstract: The invention relates to a gas-liquid heat exchanger comprising a first liquid distributor, a second liquid distributor and heat exchange assemblies connecting the first liquid distributor and the second liquid distributor. A flow equalizer plate and a liquid guiding plate are arranged on the first liquid distributor to equalize the incoming liquid. On the heat exchange assemblies are arranged longitudinally-finned tubes, which are evenly distributed in an array. The fins on two adjacent longitudinally-finned tubes are arranged in an alternating manner to achieve heat exchange assemblies providing small wind resistance, large heat transfer surface area and long heat transfer stroke. Therefore, the heat exchanger has uniform liquid distribution, small wind resistance, large heat transfer surface area, long heat transfer stroke, gas-liquid counter-flow arrangement and high heat transfer efficiency.

  • Patent number: 10876804
    Abstract: A tube-to-header sealing system for a heat exchanger comprises a pair of mating header plates, each header plate having a wall with a plurality of openings therein and including a continuous depression along the circumference of each header plate opening which forms one-half of an O-ring groove. Each of a plurality of O-rings is positioned in each O-ring groove and the header plates are secured together such that the header plate plurality of openings are aligned and trap each of the plurality of O-rings in O-ring grooves. A plurality of spaced-apart tubes each having a tube end secured in an opening in the wall of the header to form a tube-to-header joint are expanded outwardly to provide sufficient O-ring deformation to obtain a seal. In service, the resiliency of the O-ring seal allows for expansion and contraction of the tubes without the build-up of high stresses at the tube-to-header joint.

The header housing has a first wall and a second wall generally opposite the first wall where the first and second walls define a track. The insert is positioned to engage with the track such that the insert separates the header into first and second manifold chambers. A method for forming a multi-chamber heat exchanger header includes extruding a header housing having first and second manifold chambers and a track, positioning an insert in the header housing to engage with the track, and welding or brazing the insert to the header housing.

  • Patent number: 8726976
    Abstract: A heat exchanger can have a manifold which includes a plurality of laminated sheets that allow a customization of the heat exchanger. The design can allow for a more optimal flow of coolant to areas of high load, thereby making the temperature distribution across the heat exchanger more uniform, or intentionally non-uniform. Furthermore, the laminated sheets can allow multiple circuits to be employed in the heat exchanger such that different coolants can be utilized therein and maintained separate from one another. The tubes can be microchannel tubes. A single set of manifolds can be used with multiple heat exchanger cores to provide a more compact heat exchanger. Mounting features can be integral with a group of the sheets.

  • Publication number: 20140041842
    Abstract: A heat exchange chamber includes an inlet, an outlet and a plurality of walls defining a chamber interior. The inlet receives a heat exchange medium flowing in a first flow direction in an initial line of flow. Disposed within the chamber interior is a medium directing member, having an inclined surface, which diverts the medium from the initial flow direction so that it disperses within the chamber interior. Exposure to the contact surfaces provided by the chamber walls causes the medium to exchange heat with the chamber and the external environment. The medium exits the chamber, via the outlet, in the initial line of flow. The chambers are interconnected by tubes to form assemblies. Plural sets of chamber and tube assemblies are arranged between manifolds to provide a heat exchanger.
