  • Patent number: 11585604
    Abstract: A tube type heat exchanger includes a core includes multiple tubes, a header plate defining an array of apertures in which said tubes are received, and a coolant jacket arranged about said core. The header plate includes a body defining a central region and an edge region circumferential to said central region. The central region defines said array of apertures. The edge region includes a flange. The header plate is connected to the coolant jacket via first and second contact areas between the header plate and the coolant jacket. The flange is outboard of the coolant jacket. The first contact area is between the flange and the coolant jacket; and the second contact area is inboard of the first contact area.

  • Publication number: 20230023039
    Abstract: A heat exchanger includes a core having a plurality of tubes, each tube having a tube inlet and a tube outlet, and the tube inlets define an inlet plane and the tube outlets define an outlet plane. The tubes are spaced from one another for receiving a second fluid therebetween, for heat transfer between the first and second fluids. A jacket is provided adjacent the core for use in containing the second fluid, and the jacket comprises a jacket inlet for passage of the second fluid en route to the core. The jacket extends between the inlet plane and the outlet plane, and the jacket inlet is offset from the inlet plane towards the outlet plane. The heat exchanger further comprises a deflector arrangement for directing a flow of second fluid from the jacket inlet towards the inlet plane prior to entering the core.

  • Patent number: 10386129
    Abstract: A header plate includes slots to receive heat exchange tubes of a heat exchanger. Each slot includes a lip extending in a direction of the tubes. Each slot has straight sides and corners. At least two tabs extend from each lip. One tab is on one side of each lip, and another tab is on an opposite side of each lip. Tabs are absent from the corners of the lip. Each tab is turned out from the lip so that the tabs on the lip act as a lead in for a tube entering the slot. Each slot has two long sides opposite one another. At least one tab is on each long side of the lip.

  • Patent number: 9022100
    Abstract: A heat exchanger includes a core and a pair of end tanks attached to the end of the core. Each end tank extends over an outermost peripheral end of the core such that the core extends into a chamber defined by the end tank. The end tank is welded to the core at the outer surface of the core and a lower end surface of the tank.
