A liquid to refrigerant heat exchanger includes an enclosed coolant volume that is at least partially defined by a plastic housing and by a metal closure plate. The metal closure plate can be part of a brazed assembly containing a continuous refrigerant flow path. The refrigerant flow path is disposed within the coolant volume, where heat can be transferred between the refrigerant within the refrigerant flow path and the liquid within the coolant volume. The plastic housing can at least partially surround the refrigerant flow path to at least partially bound a liquid flow path along a portion of the coolant volume. An inlet diffuser and an outlet diffuser can be mounted to the housing to direct the liquid through the housing. The plastic housing is sealingly joined to the closure plate along an outer periphery of the closure plate.

High pressure capable liquid to refrigerant heat exchanger

A liquid to refrigerant heat exchanger includes a coolant volume that is at least partially defined by a plastic housing and by a metal closure plate. The plastic housing is sealingly joined to the closure plate along an outer periphery of the closure plate. The metal closure plate can be part of a brazed assembly that defines a continuous refrigerant flow path through the heat exchanger between a refrigerant inlet port and a refrigerant outlet port.

An integrated heat exchanger and coolant reservoir includes a reservoir structure that extends in a length direction from one end to an opposite end. A coolant inlet is arranged at one of the ends, and a coolant outlet is arranged at one of the ends. Coolant volumes extend in parallel along the length direction, and are fluidly connected in series to define a coolant flow path between the coolant inlet and the coolant outlet. An internal structure arranged within the reservoir structure has walls that separate individual coolant volumes from one another. Refrigerant flow paths are provided within at least one of the walls.

Integrated heat exchanger and coolant reservoir

A heat exchanger for transferring heat from a hot gas to a fluid includes two or more corrugated fin structures defining a plurality of hot gas flow channels extending in a generally linear first direction. A fluid conduit includes an outer wall at least partially bonded to at least two of the corrugated fin structures. The fluid conduit defines a plurality of sequentially arranged flow passes for the fluid traveling therethrough. Each of the plurality of flow passes directs the fluid in a direction generally perpendicular to the first direction.

Heat exchanger and method of making the same

A method is provided to vaporize a working fluid using a heat sourcing fluid. A first portion of the heat sourcing fluid passes through the first section, in counter-flow with the working fluid. A second portion of the heat sourcing fluid passes through the second section, in co-flow with the working fluid. Both the first and second portions pass through the third section, in overall counter-flow with the working fluid. The working fluid passes sequentially through the third section, the first section, and the second section. The method may be used in a Rankine cycle for waste heat recovery or in a refrigerant cycle.

A hydrogen storage and release device () is provided for storing and releasing hydrogen from a metal hydride () contained in the device () based on heat transfer to or from a coolant flow provided through the device (). The device () includes a housing () and a metal hydride containing a tube bundle located within the housing (), with the exteriors () of the tubes () of the bundle () being reduced over a selected length to provide a free flow area for the coolant flow.

Hydrogen storage and release device

An integrated heat exchanger and muffler unit () is provided for transferring heat between a first fluid and a second fluid, and for muffling the noise of the first fluid. The unit includes a housing () including a first inlet () for the first fluid, a first outlet () for the first fluid, a second inlet () for the second fluid, and a second outlet () for the second fluid. The unit () further includes a resonator () in the housing () and connected between the first inlet and outlet () to muffle noise in the first fluid, and a heat exchanger core () in the housing () connected to the first and second inlets and outlets to transfer heat between the first and second fluids. In one embodiment, the heat exchanger core surrounds the resonator. In another embodiment, the resonator surrounds the heat exchanger core.

Integrated heat exchanger and muffler unit

A heat exchanger including upper and lower header tanks, a vertical baffle in the lower header tank defining first and second longitudinal chambers, a check valve, two tube rows, and a coolant inlet to the first chamber and outlet from the second chamber. The baffle includes a by-pass hole therethrough. One tube row includes a plurality of vertical tubes extending between the upper header tank and the first chamber of the lower header tank, and the other tube row includes a plurality of vertical tubes extending between the upper header tank and the second chamber of the lower header tank. The check valve creates a leak-proof seal during standard operating mode to prevent pressure release from the header tank and creates an air path between the header tank and the environment during draining mode to allow vacuum relief from the header tank.

Weather protected heat exchanger

An integrated condenser/separator ( ) is provided for condensing and separating a condensate ( ) from a cathode exhaust gas flow ( ) in a fuel cell system ( ). The condenser/separator includes a housing ( ) and one or more baffle plates ( ) positioned in the housing ( ) to divide the interior of the housing ( ) into two or more gas flow chambers ( ) each containing a stack ( ) of heat exchange units ( ). A condensate drain ( ) is provided in each of the gas flow chambers ( ) to drain condensate therefrom. The condenser/separator ( ) can be configured into any reasonable and independent number of coolant and gas side passes as maybe required to meet the thermodynamic and pressure drop requirements of each particular application.
