A dual, dual-pass intercooler assembly for an intercooler supercharger system comprising an intercooler lid mountable to a supercharger housing; a pair of intercooler cores coupled mountable to and within at least one of the intercooler lid and the supercharger housing; wherein the pair of intercooler cores configured to receive and cool supercharger air upon a first pass through the pair of intercooler cores and receive and further cool the supercharger air upon a second pass through the pair of intercooler cores prior to receipt by an engine.

An EGR cooler includes a housing having coolant inlet and outlet, through which coolant flows into and out of the housing, and having gas inlet and outlet through which exhaust gas flows into and out of the housing, a plurality of first tubes provided in the housing while one end of each of the first tubes communicates with the gas inlet and the other end thereof communicates with one end of a connection passage, a plurality of second tubes provided in the housing while one end of each of the second tubes communicates with the gas outlet and the other end thereof communicates with the other end of the connection passage, and first and second cooling fins inserted into the respective first and second tubes, wherein the gas inlet has a larger cross-sectional area than the gas outlet.

A fresh air supply device for an internal combustion engine may include a suction module for conducting supercharged fresh air and a charge air cooler arranged in the suction module for cooling the supercharged fresh air. The suction module includes a housing with a charge air inlet for uncooled charge air and a charge air outlet for cooled charge air. The housing has a cooler shell, which may include the charge air inlet containing the charge air cooler and an assembly opening. With respect to a flow direction of the charge air the assembly opening may be arranged downstream of the charge air cooler and through which the charge air cooler is inserted into the cooler shell. The housing has a connecting shell, which includes the charge air outlet and which in the region of the assembly opening is attached to the cooler shell in an air-tight manner.

An exhaust gas recirculation cooler may include a housing having a coolant inlet opening into an inlet region and a coolant outlet, and a plurality of cooling tubes arranged in the housing next to one another to form a tube row, each cooling tube connecting an exhaust gas inlet and outlet. At least two tube rows with one arranged on top of another and spaced from each other may form a tube block. Exhaust gas may be flowable through an inside of each cooling tube, and a coolant flow may be able to be circulated outside of the cooling tubes within the housing and flowable through an annular space enclosing the tube block in a circumferential direction. A flow guide arrangement for guiding the coolant in the interior of the tube block may be arranged in the housing lying against at least portions of one of the tube rows.

An exhaust gas heat exchanger including connection points for the exhaust gas flow, for connecting the exhaust gas heat exchanger to an exhaust gas supply line for supplying a hot exhaust gas and an exhaust gas withdrawal line for withdrawing the exhaust gas flow cooled in the exhaust gas heat exchanger. The exhaust gas flow flows through the exhaust gas heat exchanger in a bundle of exhaust gas guiding pipes in a flow direction. The exhaust gas heat exchanger is provided with at least one coolant supply connection and at least one coolant withdrawal connection. Coolant is guided in a coolant channel in the exhaust gas heat exchanger, inside which it flows around the bundle of exhaust gas guiding pipes. The coolant channel includes at least two regions which differ in terms of the flow direction of the exhaust gas flow by divergent flow directions of the coolant.

A heat treatment device causing a first fluid and a second fluid to flow therethrough includes heat transfer bodies including first flow channels through which the first fluid flows and second flow channels through which the second fluid flows adjacent to the first flow channels without contact, and pipe-like members detachably placed in the first flow channels and each including a pipe wall having an outer wall surface conforming to a wall surface defining each first flow channel and an inner wall surface with which the first fluid comes into contact.

A heat exchanger for cooling a flow of media, comprising a plurality of pipes. The pipes are each received in a respective pipe base at the ends, and the pipes are received in a housing between the two pipe bases, the housing being connected to the pipe bases in a fluid-tight manner. A coolant channel is formed by a shaped region oriented outwards along an outer wall which delimits the housing. The coolant channel has an opening oriented in the direction of the inner volume of the housing, and the coolant channel is in fluidic communication with the inner volume of the housing via the opening. The opening is at least partly covered by a panel, and the panel is arranged on the housing outer wall surface oriented inwards, the outer wall having the coolant channel. A gap is formed between an edge, which delimits the opening, and the panel.

The present invention is a device for recovering energy from exhaust gas heat of an internal combustion engine. Particularly, the invention relates to a recuperator device which makes use of a temperature gradient between two conduits to generate an electric potential by means of a plurality of thermoelectric boards.
