Abstract: A battery cooling plate includes a first plate and a second plate that are joined together at their respective edges, and are spaced apart to define a coolant volume therebetween. Turbulating inserts can be arranged side-by-side within the coolant volume and multiple rods can extend through the turbulating inserts to at least partially define flow barriers between coolant flow channels. A fluid manifold for the battery cooling plate includes a non-planar wall that extends along a length-wise direction of the fluid manifold to separate a fluid volume into a first portion and a second portion. A series of apertures are arranged along the length-wise direction and successive ones of the apertures are fluidly connected to the first portion and to the second portion in alternating sequence.

Abstract: A plate assembly for a heat exchanger includes a first plate, a second plate, and an intermediate plate arranged between the first and second plates. The intermediate plate is joined to the first and second plates at peripheral edges to create a sealed periphery of the plate assembly. Corrugations of the intermediate plate provide crests and troughs that are in contact with inwardly facing surfaces of the first and second plates. The plate assembly can be configured as a battery cooling plate heat exchanger to transfer heat from a battery to fluid flowing through the plate assembly.

Abstract: A liquid to refrigerant heat exchanger is provided having a stack of nested plates with fluid flow passages defined between the plates. The stack includes a condenser portion and a subcooler portion. A base plate at a bottom end of the stack has a refrigerant outlet port and a receiver bottle joined to it. A receiver flow path extends through a structural connection joining the receiver bottle to the base plate to allow for fluid flow between an internal volume of the receiver bottle and the condenser portion. Another receiver flow path extends through another structural connection to allow for fluid flow between an internal volume of the receiver bottle and the subcooler portion.

Abstract: A rapid warm-up heat exchanger for heating a fluid using exhaust gas includes multiple plate pairs that are joined by braze joints to form a stack. A fluid inlet manifold and a fluid manifold extend through the stack, and each one of the plate pairs defines a tortuous flow path for the fluid that extends between the fluid inlet and fluid outlet manifolds. A housing surrounds the stack, and together the housing and the stack define an exhaust flow path in spaces provided between adjacent plate pairs. A valve element can be provided within the housing in order to selectively direct exhaust flow through the exhaust flow path.

Abstract: A heat exchanger that transfers heat from an exhaust gas flow to a liquid coolant includes a first heat exchange section and a second heat exchange section located adjacent the first heat exchange section. The first heat exchange section is located within a first housing that at least partially encloses a first fluid volume. The second heat exchange section is located within a second housing that at least partially encloses a second fluid volume. A first plurality of heat exchange tubes traverses the first heat exchange section, and a second plurality of heat exchange tubes traverses the second heat exchange section. An exhaust gas flow path of the heat exchanger includes the first fluid volume and the interiors of the second plurality of heat exchange tubes. A coolant flow path of the heat exchanger includes the second fluid volume and the interiors of the first plurality of heat exchange tubes.
