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.

Exhaust gas heat exchanger

Exhaust gas heat exchanger and method

The present invention provides a charge air cooler for transferring heat between a coolant and charge air including a charge air inlet tank, a charge air outlet tank spaced from the inlet tank, a housing connecting the inlet and outlet tanks to define a charge air flow path from the inlet tank to the outlet tank, and a plurality of plate pairs extending into the charge air flow path from, and substantially perpendicular to, a first wall of the housing. Each of the plate pairs can define a multi-pass path for the coolant. Elongated spacers can be positioned between adjacent plate pairs to define the first wall of the housing. The housing can include a second wall opposite the first wall, and the plate pairs can be spaced away from the second wall in order to accommodate differences in thermal expansion between the plate pairs and the housing.

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.

Method of manufacturing a heat exchanger having a contoured insert

A liquid cooled charge air cooler includes a plurality of pairs of adjacent separator plates supported in parallel spaced relation. The pairs alternatingly define a first set of adjacent pairs in fluid communication with a charge air inlet and a charge air outlet, and a second set of adjacent pairs in fluid communication with a coolant inlet and a coolant outlet. Fins extend between adjacent plates of the first set of adjacent pairs to define a charge air flow path between the charge air inlet and the charge air outlet. A plurality of dams extend between adjacent plates of the second set of adjacent pairs in a select offset configuration to define a multi-pass coolant flow path between the coolant inlet and the coolant outlet. Each dam includes an associated bypass port allowing a portion of coolant to bypass at least a portion of the coolant flow path through the dams.
