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.

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.

The present invention provides an exhaust gas recirculation cooler for transferring heat from engine exhaust to coolant including a pair of spaced apart headers, a tube body extending between the pair of headers and positioned along a flow path for the coolant and at least partially defining a flow path for the engine exhaust along a length of the tube between the pair of headers, and a corrugated insert supported in an interior of the tube and having a height in a direction of a plurality of corrugations and a width between about 8.6 and about 13.5 times the height. The width can be substantially perpendicular to the length of the tube and can be substantially perpendicular to the height of the insert.

A heat exchanger for transferring heat between a first working fluid and a second working fluid, including a pair of spaced apart headers, a number of tubes extending between the pair of headers and providing a flow path for the first working fluid and being positioned along a flow path for the second working fluid, and an insert supportable in one of the tubes and having a fold extending in a direction substantially parallel to the flow path for the first working fluid through the tubes. The fold can define first and second legs of the insert. A dimple can be formed on the first leg and a protrusion can be formed on the second leg opposite to the dimple on the first leg.

An improved combustion air charger, such as a turbocharger or a supercharger, includes a housing () having a rotary shaft () journalled therein. At least one compressor wheel () is located on the shaft (). The housing () includes an ambient inlet () as well as a compressed air outlet () and a heat exchanger () is located between at least one of the compressor wheels () and the outlet () and is arranged so that air flow through the heat exchanger () is generally in the radially inward direction.

A header construction intended for use in a heat exchanger () employed in a relatively high pressure application includes an array of generally parallel tube runs () with fins () extending between adjacent ones of the tube runs. At least one relatively flat header plate () has a plurality of tube slots () for receiving ends () of the tubes () and a tank () is mounted to and sealed to the header plate (). Peripheral flanges () are located about tube slots () in the headers and a header reinforcing plate () is bonded to the header plate () oppositely of the tank (). Stiffening beads in the form of flanges () are located on the header reinforcing plate () between openings () therein through which the tubes () pass and extend away from the header plate ().

A compact rotary compressor unit within internal intercooling includes a rotary shaft () with at least one compressor wheel () mounted thereon for rotation therewith. The compressor wheel () has an inlet end () of relatively small diameter and a radial discharge end () of relatively large diameter. A nominally donut-shaped intercooling heat exchanger () is centered about the shaft () to receive compressed air from the compressor wheel and cool the same. Both the compressor wheel () and the heat exchanger () are confined in a housing ().

A turbulator ( A- K) is provided for use in the heat exchange units ( ) of heat exchangers. The turbulator ( A- K) includes a sheet ( A, C) of material. The sheet ( A, C) includes a plurality of strand-like rows ( A, C) of alternating crests ( A, C) and valleys ( A, C). The crests ( A, C) and valleys ( A, C) in each row ( A, C) are offset with respect to the crests ( A, C) and valleys ( A, C) in any immediately adjacent row ( A, C). Each of the rows ( A, C) has an interface with any immediately adjacent row ( A, C). The interfaces are perforated so that valleys ( A, C) in each row ( A, C) are in fluid communication with immediately adjacent crests ( A, C) in any immediately adjacent row ( A, C) and crests ( A, C) in each row ( A, C) are in fluid communication with any immediately adjacent valleys ( A, C) in any immediately adjacent row ( A, C). In some preferred embodiments ( A, C, D, E, F, H, J, K), the plurality of rows ( A, C) are divided into at least two groups ( A, C, J; A, C, J) which together define a herringbone pattern of the crests ( A, C) and valleys ( A, C).
