  • Patent number: 10126068
    Abstract: A heat exchanger apparatus includes a housing that defines a flow passage for a first fluid. The housing has a housing fluid inlet and a housing fluid outlet communicating with the flow passage. A first heat exchanger is located within the flow passage of the housing between the housing fluid inlet and the housing fluid outlet. The first heat exchanger has a plurality of channels for transmitting a second fluid through the first heat exchanger. The heat exchanger apparatus also includes a flow diverter in the flow passage, between the housing fluid inlet and the first heat exchanger, for diverting some of the first fluid to a by-pass region of the flow passage that by-passes the first heat exchanger. As well, a flow control device is in communication with the housing fluid inlet and controls a volume and location of the first fluid entering the flow passage.

  • Patent number: 8857503
    Abstract: A by-pass conduit for a stacked plate heat exchanger is disclosed. The by-pass conduit is formed by first and second plate members that each have a substantially planar central portion surrounded by an offset peripheral flange, the peripheral flanges of the first and second plates being sealably joined together and the planar central portions of the first and second plates being in spaced opposition to define a bypass channel. A flow restricting structure provides a fluid restricting barrier in the bypass channel, the flow restricting structure defining a calibrated by-pass passage that regulates the flow of fluid through the bypass channel.

  • Patent number: 8678077
    Abstract: A plate type heat exchanger having a plurality of stacked plate pairs made up of first and second plates. Each plate pair has opposed manifold members that form respective inlet and outlet manifolds for the flow of a first fluid through a first set of fluid channels formed by the plate pairs. The manifold members space the plate pairs apart to form a second set of transverse flow channels for the flow of a second fluid. A protrusion member is formed at an end portion of the plates and proximal to each of the manifold members and has a mating surface, such that the protrusion members on the second plate of one plate pair align and abut with the protrusion members on the first plate of an adjacent plate pair thereby reinforcing and strengthening the manifold region of the heat exchanger to prevent deformation of the manifold under pressure.

  • 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.
