A heat exchanger, in particular an exhaust gas cooler or charge air cooler, is provided that includes a plate stack which has a plurality of elongated plate pairs, each set of two interconnected plates forming a respective second fluid channel between themselves, and a first fluid channel being formed between two plate pairs, a first fluid channel being surrounded by two second fluid channels, each second fluid channel being connected to at least one manifold.

Heat exchanger

The invention relates to a heat exchanger, particularly for a motor vehicle, comprising a plurality of exchanger tubes () attached to at least one floor for conveying a first fluid, wherein the exchanger tubes () are disposed in a housing through which a second fluid flows, wherein a holding member () is disposed inside the housing, wherein at least two of the exchanger tubes () are supported relative to one another by means of the holding member ().

Heat exchanger, particularly for a motor vehicle

A heat exchanger, particularly an exhaust gas heat exchanger, for transferring heat in two stages between a first fluid and second and third fluids that have different temperatures includes a block for separately conducting the first and second and third fluids in a heat transferring manner. The block encompasses a number of ducts through which the first fluid can flow, a first chamber of a high-temperature part through which the second fluid can flow and which accommodates the ducts, a second chamber of a low-temperature part through which the third fluid flows and which accommodates the ducts, and a housing in which the first and second chamber as well as the ducts are arranged. The first chamber and the second chamber are separated from one another by a separation area that is mounted in a groove.

Heat exchanger, exhaust gas recirculation system, and use of a heat exchanger

A flow channel for a heat exchanger for exchanging heat between a first fluid and a second fluid, the flow channel having, perpendicular to a flow channel axis, a cross-section that can be traversed, the flow channel providing for an improved transfer of heat with an acceptable drop of pressure and a reduced risk of blocking. The flow channel has a hydraulic diameter, defined as quadruple the ratio between the surface of the cross-section that is traversed and the perimeter that can be moistened by the fluid, of between 1.5 mm and 6 mm. Also a heat exchanger having a plurality of flow channels of this type, through which the first fluid flows and fluidically connected by a fluid connection. Also a charge-air system and an exhaust gas recycling system having such flow channels.
