An electric heating device in an exhaust gas system, the device having an outer circumferential, circular, housing, wherein a rib structure is arranged in the housing. The rib structure can be heated by applying an electric current. The rib structure is arranged with rib rows parallel to one another in the housing, wherein the parallel-arranged rib rows are arranged such that they are electrically connected to one another in series or in parallel.

Electric heating device

An exhaust gas treatment device for arranging in an exhaust gas section of a motor vehicle that includes a heating disk which is assigned to an exhaust gas aftertreatment component. The heating disk is configured by way of a flat heating element and a holder which is coupled to the former. The holder extends over the cross-sectional area of the heating element, and the holder itself is of disk-shaped configuration. The inner face of the heating disk is configured by way of arcuate spokes which are coupled irregularly to one another.

Holder for an electric heating disk in an exhaust gas aftertreatment device

A plate heat exchanger has two metal plates brought into abutment, with a solder material between the plates. The plates are heated up to a first temperature. The plates are placed into a mold, the mold surfaces of which have cavities for envisaged channel structures. Channel structures are formed by local internal pressure forming of at least one plate under pressurization by the tool. The plates are heated up to a second temperature. The plates are solder bonded at the abuted surfaces. A plate heat exchanger has two metal plates, wherein channel structures have been formed in at least one plate and the plates are bonded to one another by soldering away from the channel structures. Eutectic microstructures having a longest extent of less than 50 micrometers are formed in the solder layer.

Process for producing a plate heat exchanger and plate heat exchanger

An exhaust-gas treatment device for arrangement in an exhaust system of a motor vehicle, having a heating element, which is assigned to an exhaust-gas aftertreatment component, for example, a catalytic converter. The heating element is formed by a heating conductor and by a holder coupled to said heating conductor, wherein the holder extends over the cross-sectional area of the heating element, and the holder is formed by a lattice-like structure, wherein the lattice-like structure is formed by arcuate spokes which are coupled to one another in an irregular manner, wherein the heating conductor and the holder have a basin-like configuration as viewed in longitudinal section in an exhaust-gas flow direction.
