A control unit, in particular for a motor vehicle, the control unit having a housing, which has at least one heat dissipating area in which at least one electrical and/or electronic module having at least one heat dissipating element is situated, it being provided that the heat dissipating element is heat conductively connected to the heat dissipating area via a heat conducting medium which is introduced into the interior of the housing through at least one housing opening and which has a paste-like consistency, at least when introduced. A corresponding method for manufacturing a control unit is also described.

1. A control unit for a motor vehicle, comprising: a housing which has at least one heat dissipating area;at least one electrical or electronic module having at least one heat dissipating element, the module being situated in the heat dissipating area; anda heat conducting medium which is introduced into an interior of the housing through at least one housing opening situated in the heat dissipating area, and which has a paste-like consistency at least when introduced, the heat dissipating element being conductively connected to the heat dissipating area via the heat conducting medium, wherein:the housing is a rack mount housing into which the module is inserted,the control unit has a guide for inserting the module,the guide is designed as a guide channel,a structure of the guide that forms the guide channel includes as part of the structure at least one indentation for clamping the module on an edge,the at least one indentation applies a downward clamping force directly on the module to establish a permanent contact between a contact surface of the module and the rack mount housing in the heat dissipating area,the guide channel is a U-shaped space defined by opposing sides of the structure and occupied by the edge of the module,the indentation is located in only one of the opposing sides and narrows the guide channel in relation to a remaining portion of the guide channel where the indentation is absent, andthe clamping occurs at the narrowed location of the guide channel. 2. The control unit as recited in claim 1, wherein the heat conducting medium fills a gap space in the housing interior located between the heat dissipating element and the heat dissipating area. 3. The control unit as recited in claim 1, wherein the heat dissipating element extends into the guide. 4. The control unit as recited in claim 1, wherein the guide is located in a zone of the heat dissipating area. 5. The control unit as recited in claim 1, wherein a section of the housing forms the guide channel. 6. The control unit as recited in claim 1, wherein the module has a printed circuit board which is accommodated in the guide channel. 7. A method for manufacturing a control unit for a motor vehicle, comprising: providing a housing, having at least one heat dissipating area;situating at least one electrical or electronic module having at least one heat dissipating element in the heat dissipating area;introducing a heat conducting medium into an interior of the housing through at least one housing opening situated in the heat dissipating area, the heat conducting medium having a paste-like consistency at least when introduced;wherein the heat dissipating element is heat conductively connected to the heat dissipating area via the heat conducting medium, wherein: the housing is a rack mount housing into which the module is inserted,the control unit has a guide for inserting the module,the guide is designed as a guide channel,a structure of the guide that forms the guide channel includes as part of the structure at least one indentation for clamping the module on an edge,the at least one indentation applies a downward clamping force directly on the module to establish a permanent contact between a contact surface of the module and the rack mount housing in the heat dissipating area,the guide channel is a U-shaped space defined by opposing sides of the structure and wide enough to accommodate the edge of the module,the indentation is located in only one of the opposing sides and narrows the guide channel in relation to a remaining portion of the guide channel where the indentation is absent, andthe clamping occurs at the narrowed location of the guide channel.
