Definitions
- the invention relates to a control unit, in particular for a motor vehicle, wherein the control unit has a housing having at least one réelleableit Suite, in which at least one electrical and / or electronic assembly is arranged, which has at least one heat dissipation element.
- DE 101 41 697 describes a control device with a printed circuit board which has a heat-emitting electrical component.
- the electrical component is cooled by being able to deliver its heat to a housing surrounding the circuit board.
- the housing is provided with an area which is able to dissipate heat.
- the printed circuit board is placed in touching contact with the heat-conducting region.
- the heat dissipation element is thermally conductively connected to the heat dissipation region by means of a heat-conduction medium introduced into the interior of the housing by at least one housing opening, at least during introduction of the heat-conducting medium. It is thereby achieved that an air gap or a space between the heat dissipation element and the heat dissipation area is filled. This justifies an optimal thermally conductive connection between the assembly and the housing. Due to the housing breakthrough, it is possible to the heat transfer medium To bring inside the housing, which are difficult to reach from the outside during manufacture.
- the design of the housing breakthrough depends on the heat-conducting medium used and the geometry of the heat-dissipating element and the heat-dissipating region.
- a circular housing opening or a slot-shaped housing opening is conceivable.
- the pasty heat-conducting medium hardens after introduction, so that the housing opening is tightly closed. In this way it is possible to realize the advantages of the invention in a sealed housing concept for the control unit.
- the use of pasty slaughterleitmediums brings the advantage that both small air gaps and larger spacings between the heat dissipation element and the sauceableit Scheme be filled and thus thermally optimally overcome. The consequence is a high flexibility in a design and the production of the control unit while maintaining the optimum thermally conductive connection.

Since it is particularly difficult for a plug-in housing to produce an optimal thermal connection between the inserted assembly and the housing, the invention is of particular advantage here. This is based on the fact that after inserting the module can not be checked whether the heat dissipation element is optimally in contact with the politiciansableit Scheme.
- the control device for the insertion of the module has a guide.
- the use of a guide makes it possible to simply and safely insert the assembly into the housing and to fix and support the assembly within the insertion housing.

- the guide lies in the zone of the heat dissipation region. This allows a direct dissipation of heat in the guides.
- the guide is designed as a guide trough.
- the guide channel preferably has a U-shaped cross-section and thus encloses the component at least partially from three sides, whereby it is supported and secured in three directions.
- a portion of the housing forms the guide trough.
- the plug-in housing is designed so that it, even forms the guide channel.
- corresponding wall profiles of the housing can be provided for this, which form the guide channel.
- the guide channel is provided with at least one indentation for edge-side clamping of the module.
- the assembly has a printed circuit board which is received in the guide trough.
- the design of the module as a circuit board allows easy guiding of the module by means of the guide.
- the invention further relates to a method for producing a control device, in particular according to the preceding description, in particular for a motor vehicle, wherein the control device has a housing having at least one heat dissipation region, in which at least one electrical and / or electronic assembly is arranged, the at least one heat dissipation element wherein the heat dissipation is connected to the politiciansableit Scheme by means of a introduced into the interior of the housing by at least one housing opening, at least during introduction pastturas heat conduction medium thermally conductive.
