A heat exchanger includes at least one first flow channel for a first medium, at least one second flow channel for a second medium, and at least one bottom that can be connected to the housing. The bottom has at least one expansion element.

Heat exchanger

An internal combustion engine may include a housing and at least one cavity arranged therein for receiving a coolant flow. An exhaust gas cooler may be provided for cooling an exhaust gas flow. The exhaust gas cooler may be configured as a stacked disc cooler including at least two stacking discs, an exhaust gas inlet, a cover plate and a screw-mounting plate for screw-mounting to the housing. The exhaust gas cooler may protrude into the cavity of the housing when the screw-mounting plate is mounted to the housing. The screw-mounting plate may have a spacer element disposed at the exhaust gas inlet. The spacer element may protrude in a direction of the at least two stacking discs and enlarge a distance between the screw-mounting plate and an adjacent stacking disc of the at least two stacking discs to position the exhaust gas cooler further into the cavity.

Internal combustion engine

The invention relates to a heat exchanger, especially for cooling exhaust gases. Said heat exchanger comprises at least one first flow channel for a first medium, at least one second flow channel for a second medium, at least one bottom that can be connected to the housing, said bottom having at least one expansion element.

A heat exchanger for heat exchange between a first fluid and a second fluid is provided that includes: a block for guiding the first fluid and the second fluid separately and in a heat-exchanging manner, and a fluid connection for the first fluid. The block comprises a housing provided with a chamber through which the second fluid can flow, and a block end element for the fluid-tight separation of the chamber and the fluid connection. The housing can be provided for connecting the block to the fluid connection. The block end element is not used to connect the block to the fluid connection but rather preferably only the housing. The housing can be thickened accordingly in the region of the block connection. The fixing point for the block end element to the housing and the fixing point for the fluid connection to the housing are at a distance from each other.

Heat exchanger, exhaust gas recirculation system, charge air supply system, and use of the heat exchanger

An exhaust-gas cooler for a motor vehicle is provided that includes a flow path which can be traversed by exhaust gas of an internal combustion engine and which has an inlet region and an outlet region for the exhaust gas, a housing which surrounds the flow path and which has at least one inlet and at least one outlet for a liquid coolant of a coolant circuit, wherein the coolant can flow around the flow path in order to cool the exhaust gas, and wherein the coolant circuit is formed as a main cooling circuit of the internal combustion engine of the motor vehicle, wherein the exhaust-gas cooler is arranged in the main cooling circuit in series with the internal combustion engine.
