Patent ID: 8885343

Claim:
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; and a 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, and the clamping occurs at the narrowed location of the guide channel.
