Device for exchanging heat between an acidiferous gas and a heat transfer medium, with at least one flow duct for the acidiferous gas which consists essentially of aluminum and/or an aluminum alloy.

Device for exchanging heat for gases containing acids

A device for cooling a gas flow of an internal combustion engine includes a housing, an inlet and an outlet for a gas of the internal combustion engine, which is to be cooled, an inlet and an outlet for a liquid coolant, a heat exchanger for heat transfer between the gas and the coolant, a first wall section of the housing, wherein the first wall section is arranged between the coolant and the gas flow, and a second wall section of the housing, wherein the second wall section is arranged between the coolant and the atmosphere, wherein the first wall section and the second wall section are integrally formed in one piece.

Device for cooling a gas flow of an internal combustion engine

The invention relates to a heat exchanger (or a motor vehicle, comprising a first flow path () with a number of flow conduits () for conducting a fluid to be cooled, a deflection region (), situated downstream of the first flow path () and a second flow path (), situated downstream ol the deflection region (). According to the invention, the flow conduits () of the first flow path () continue in the deflection region () and the second (low path () as continuous separate flow conduits (). The invention also relates to a flow conduit () for a heat exchanger () for exchanging heat between a first fluid () and a second fluid (). The aim of the invention is to guarantee an improved transfer of heat with a simultaneous acceptable pressure drop, whilst reducing the blocking risk.

Heat exchanger for a motor vehicle

The invention relates to a soldering work piece made of aluminium and/or aluminium compounds, to a soldering method, in addition to a heat exchanger soldered in said manner. One surface of the soldering work piece is provided with an artificially applied oxide layer.

Soldering work piece, soldering method and heat exchanger

Disclosed is a heat exchanger for a combustion engine, comprising a first connection zone () for delivering a fluid that is to be cooled, at least some of said fluid being composed of exhaust gas of the combustion engine, a second connection zone () for discharging the fluid, and an exchanger zone () which is arranged between the first and the second connection zone relative to a flow path of the fluid. A coolant can flow around the exchanger zone () while at least part of the heat exchanger is made of ferritic steel.

Heat exchanger for a combustion engine

The invention relates to a soldering flux based on potassium fluoroaluminates, wherein the zirconium fluoride and/or titanium fluoride is added to the soldering flux. The invention also relates to a corresponding soldering method.
