The invention relates to a fluid channel for a heat exchanger, comprising a metal sheet, wherein the metal sheet has at least one core region of an aluminum base alloy and at least one structure arranged inside the fluid channel, wherein the structure lies against a surface of the metal sheet and can be soldered to the metal sheet in a flux-free manner by way of a first soldering location in a soldering operation, and wherein a soldering region of the metal sheet and a counterpart lie against one another and can be soldered to one another in the same soldering operation as a second soldering location while wetting with flux, wherein an open path between the two soldering locations exists before the soldering operation.

Solderable fluid channel for a heat exchanger of aluminum

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.

The invention relates to a method for producing a metal part. Said method comprises the steps of supplying a strand of metal material and applying a coating from a fluxing agent composition to a surface of the strand of material by means of an application device (), said fluxing agent composition being applied to only a defined portion of the surface of the strand of material by means of the application device ().

Method for producing a metal part

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 method for soldering components, in particular heat exchanger, in particular made of aluminum materials, aluminum alloys or wrought alloys, in a soldering furnace, in particular a continuous soldering furnace or a batch-type soldering furnace, which comprises a muffle, which is flushed with protective gas in order to create a protective atmosphere. In order to make the production of soldered components easier, during the soldering of the components the muffle is supplied with such a greatly increased amount of gas, in particular protective gas or reaction gas, that a low-oxygen protective atmosphere is created.

Method for soldering components

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

A multi-layered brazing sheet with improved long life corrosion resistance achieved by balancing the Zn, Cu, Mn, Si and Mg content of the core and interliner alloy. The brazing sheet has a core of a 3xxx alloy, an inner braze cladding of a 4xxx alloy, and between core and inner braze cladding an interliner of a 3xxx alloy. The 3xxx alloy of the core has 0.55-1.0 wt % Cu, 0.7-1.8 wt % Mn, &#x3c;0.3 wt % Mg, &#x3c;0.4 wt % Zn. The 3xxx alloy of the interliner has &#x3c;0.25 wt % Cu, 0.5-1.5 wt % Mn, &#x3c;0.3 wt % Mg, 0.1-5.0 wt % Zn. A 1xxx or 7xxx alloy could be used for the interliner instead of the 3xxx alloy.

Multi-layered brazing sheet

The invention relates to an exhaust gas heat exchanger for motor vehicles, comprising a cluster of exhaust pipes () which are soldered on the front surface thereof to pipe bottoms, and a housing jacket () which is welded to the pipe bottoms (). According to the invention, the pipe bottoms are welded to the housing jacket () by means of peripheral welds ().
