The invention relates to a supply module () for conveying an operating/auxiliary agent capable of freezing for the exhaust gas aftertreatment of an internal combustion engine and for heating a reservoir holding the operating/auxiliary agent capable of freezing. The supply module () comprises a main heater () and an auxiliary heater (), which are electrically contacted on a supporting body (). A pot wall () of a heating pot () comprises electrical contacts () of the main heater () and electrical contacts () of the auxiliary heater ().

Supply module having a heating device for conveying an operating/auxiliary agent capable of freezing

The invention relates to a tank device () of a motor vehicle for a reductant for the aftertreatment of the exhaust gas of the motor vehicle, comprising a reservoir () for the reductant and a tank installation unit () having at least one conveying pump () for conveying the reductant out of the reservoir () to a point of introduction into an exhaust gas tract of the motor vehicle, wherein the tank installation unit () has a heating device () arranged adjacent to the conveying pump (), wherein at least one auxiliary heater () is provided, and wherein the auxiliary heater () is integrated in a wall () of the reservoir ().

Tank device

An electrical device has a housing and a housing surface, at least one electrical conductor accommodated in said housing and interrupting said housing surface in sections so that said housing surface is interrupted, a conductive body which covers said conductor on said interrupted housing surface, and at least two spacers which keep said conductive body apart from said at least one conductor.

Electrical device

A regulator unit, in particular for varying an exciter current, preferably for generators of motor vehicles, is proposed, having a housing (), in which the housing () has a wiper contact mounting region () with a guide () and wiper contacts () seated therein, having a regulator housing portion (), in which an electronic controller unit and a regulator heat sink () are received, having a plug element () for electrically connecting the regulator unit () to external contact elements, and in which the regulator unit () has a first through opening () and a second through opening (), by means of which openings the regulator unit () can be fastened to a housing () by means of two bolt elements (). It is provided that the regulator heat sink () is located between the wiper contact mounting region () and the plug element ().

Regulator unit and generator

An electronic component formed as a regulator for generators in motor vehicles has an IC block arranged on a cooling body, connectors provided with conductors, bond wire connectors connecting the IC block with the conductors, the conductors being provided at first ends which face the IC block with a first bond pad, forming a limited free space behind the first bond pad as seen from the IC block for insertion and withdrawal of a bond tool, the conductors of the plug connectors being each provided with a second bond pad located behind the limited free space at a distance from the first bond pad, for further bond wire connections of at least one selectively useable electronic component.

Electronic component, in particular regulator for generators in motor vehicles

In an electrical machine, in particular a generator for a motor vehicle, having a housing (), a rotor (), supported rotatably in the housing () about a pivot axis (), at least one fan wheel (), connected to the rotor (), for generating a cooling air flow (&#x2033;) from at least one intake opening (&#x2033;) disposed in the housing () to at least one outlet opening () disposed in the housing (), and at least one regulator chip (), disposed on a chip holder (), for regulating the current generation, it is provided that the chip holder () is disposed such that it is bathed at least in part directly by the cooling air flow (&#x2033;). As a result of this arrangement, it is attained that a very high heat transfer coefficient is present, because of the high flow speed of the cooling air flow (&#x2033;).
