In an exhaust train for an internal combustion engine having an integrated thermoelectric generator, the exhaust train has at least one duct, through which exhaust gas flows and in which at least one thermoelectric module is arranged in such a way that the hot side of the thermoelectric module is in direct contact with the exhaust gas, while the cold side of the thermoelectric module is cooled by means of a heat transfer medium.

Exhaust train having an integrated thermoelectric generator

A thermoelectric generator includes a thermoelectric module and a micro heat exchanger. The thermoelectric module includes p- and n-conducting thermoelectric material pieces which are alternately connected to one another via electrically conductive contacts. The thermoelectric module is thermally conductively connected to a micro heat exchanger. The micro heat exchanger includes a plurality of continuous channels having a diameter of at most 1 mm, through which a fluid heat exchanger medium can flow.

Thermoelectric modules for an exhaust system

In a method for producing form bodies for heat exchangers, comprising a thermomagnetic material, said form bodies having channels for passage of a fluid heat exchange medium, a powder of the thermomagnetic material is introduced into a binder, the resulting molding material is applied to a carrier by printing methods, and the binder and if appropriate a carrier are removed subsequently and the resulting green body is sintered.

Printing method for producing thermomagnetic form bodies for heat exchangers

What is described is the use of alcohols, alcoholamines, diols, polyols or mixtures thereof in heat carrier media or as heat carrier media which are in contact with magnetocaloric materials.

Heat carrier medium for magnetocaloric materials

Provided is a packed heat exchanger bed composed of thermomagnetic material particles having a mean particle diameter of 50 &#x3bc;m to 1 mm. The packed bed has porosity of 30-45%. A thermomagnetic material is a metal containing material such as (AB)CDE, La(FeAl)Hor La(FSi)H, La(FeAlCo)or La(FeSiCo), LaMnFeGe, Heusler alloys, Gd(SiGe), FeP-based compounds, manganites of the perovskite type, Tb(SiGe), XTiGe, MnZSb, or MnZSb, wherein A-E, P, and Z represent various metal atoms.

Process for preparing 1,3-disubstituted imidazolium salts of the formula I 

Method for the production of disubstituted imidazolium salts

A thermomagnetic generator which converts thermal energy to electrical energy without intermediate conversion to mechanical work and which works at temperatures in the range from &#x2212;20&#xb0; C. to 200&#xb0; C. comprises a thermomagnetic material selected from, for example,

Thermomagnetic generator

A method for applying at least one layer, selected from diffusion barriers, further protective layers, adhesion promoters, solders and electrical contacts, onto thermoelectric materials, is characterized by the fact that the at least one layer is rolled or pressed onto the thermoelectric material at a temperature at which the thermoelectric material is flowable.
