  • Patent number: 10302366
    Abstract: A brazed heat exchanger includes plates that are stacked or nested to define flow channels for multiple media. Inserts are arranged within at least some of the flow channels. Two different braze alloys having compositions based on different metals are used to form braze joints between the plates and the inserts. In some cases, a copper-based braze alloy is used for joints corresponding to flow channels for one of the media in order to provide high pressure-resisting strength to those flow channels, while an iron-based braze alloy is used for joints corresponding to flow channels for another of the media where dissolved copper is undesirable.

  • Patent number: 10302365
    Abstract: Disclosed is a heat exchanger having heat exchange plates and a base plate that can help to mitigate the thermal stresses encountered by a heat exchanger, particularly, around the peripheral edge portions of the heat exchanger and the base of heat exchanger. This is achieved by providing a channel of coolant fluid near the peripheral edge portions which is in between the peripheral edge portions and the manifold permitting flow of hot fluid. In addition, the base plate of the heat exchanger is protected from the hot fluid flowing through the manifold by providing deflectors that shield the base plate from the hot fluid.
