The chambers may be partially open to one another such that the steps influence a momentum of coolant traveling from the first to the second chamber. A pair of endplates may be disposed on either end of the array and configured to retain the frames therebetween. Each of the frames may further define a pair of channels and may be arranged with one another to define a power stage cavity therebetween. A power stage may be disposed within the power stage cavity.

A refrigerant distributer includes a plurality of plates. The refrigerant distributer is configured to divert, into a plurality of refrigerant flows, refrigerant flowing in from one or a plurality of inlet ports thereof and allow the refrigerant flows to be let out from a plurality of outlet ports thereof spaced from one another in a first direction. The plurality of plates include: an inflow plate having one of the plurality of inlet ports; a communication plate having a communication chamber communicating with the one of the plurality of inlet ports of the inflow plate; and a heat transfer tube insertion plate into which a heat transfer tube communicating with one of the plurality of outlet ports is inserted, the heat transfer tube insertion plate having heat transfer tube insertion space through which a plurality of the heat transfer tubes communicate with the communication chamber.

A heat exchanger header includes a primary fluid duct extending between a fluid port and a first branched region, a plurality of secondary fluid ducts fluidly connected to the primary fluid duct at the first branched region, wherein an overhang region is formed laterally between adjacent ones of the plurality of secondary fluid ducts, and wherein each of the plurality of secondary fluid ducts extends between the first branched region and a second branched region, a plurality of tertiary fluid ducts fluidly connected to each of the plurality of secondary fluid ducts at the second branched regions, a primary horn integrally formed with and extending from the overhang region, an at least one secondary horn integrally formed with and extending from one of the plurality of tertiary fluid ducts, and a sacrificial support structure extending between the primary horn and the at least one secondary horn.

The fluid connector assembly includes a connector body with an intermediate portion that extends between opposite end portions and has a first bore. The connector body has an elongated wall that projects outwardly from the intermediate portion and that surrounds a second bore which opens to the first bore. A flat tube, which is made of a second material that is different than the first material and has at least one fluid passage, is in fluid communication with the second bore of the connector body. The flat tube has generally flat side walls and is lockingly retained with the connector body by male and female locking structures that cooperate with one another.

A cooling module is coupled to an engine system and a Rankine cycle waste heat recovery system. The cooling module includes a heat exchanger for cooling a fluid of the engine system and a condenser for cooling a working fluid of the Rankine cycle waste heat recovery system, both of which extend in a width direction of the cooling module and are porous to a flow of cooling air in a depth direction of the cooling module. The condenser includes a first tubular header that extends in a height direction of the cooling module. A working fluid transfer tube fluidly couples the first tubular header to the Rankine waste heat recovery cycle system. The working fluid transfer tube has a first portion extending in the depth direction and a second portion extending in the height direction, the second portion being adjacent to the first tubular header in the width direction.

The invention relates to a heat exchange device characterized by a particular configuration of the liquid inlet or outlet manifold in which it incorporates a baffle formed from the shell itself. This configuration allows not only suitably orient the inflow into regions of the tube bundle of the exchanger where convection must be more intense, but also allows generating a flow suitable for reaching all the regions having a higher convective heat transfer requirement. Configuring a baffle from the shell prevents incorporating and manufacturing specific additional parts, as well as the additional operations required for their configuration and attachment to the heat exchanger.

A heat exchanger header includes a primary fluid duct extending between a fluid port and a first branched region, a plurality of secondary fluid ducts fluidly connected to the primary fluid duct at the first branched region, wherein an overhang region is formed laterally between adjacent ones of the plurality of secondary fluid ducts, and wherein each of the plurality of secondary fluid ducts extends between the first branched region and a second branched region, a plurality of tertiary fluid ducts fluidly connected to each of the plurality of secondary fluid ducts at the second branched regions, a primary horn integrally formed with and extending from the overhang region, an at least one secondary horn integrally formed with and extending from one of the plurality of tertiary fluid ducts, and a sacrificial support structure extending between the primary horn and the at least one secondary horn.
