A housing for electronic control units, in particular in motor vehicles, having a bottom section for attaching the electronic control units and having a cooling device that enables heat to be dissipated from the housing via a flowing liquid, a cooling device formed in the bottom section being provided both for improving the cooling capacity and for rigidity. The bottom section is easily manufactured with an integrated cooling channel by injection molding, while cooling is achievable by a medium available in the motor vehicle.

Housing for cooling electronic control units in motor vehicles

An electrical device is provided, including a housing, a base, a cover, and a plug body connected to a printed-circuit board and projecting from housing. To achieve an excellent seal for the housing in a transitional region among the base, the cover, and an intermediate wall of the plug body, a groove is formed in the cover, in which a sealing compound is placed. During assembly of the components, the sealing compound is displaced from the intermediate wall in a region of an additional sealing compound applied to the base, the two sealing compounds meeting in an overlap region.

Housing for an electrical device, in particular a switching device or a control device in a motor vehicle

An electrical device is proposed which has a housing ( ), comprising at least two housing parts ( ), and an electronic circuit disposed in the housing ( ). A connection device ( ) for supplying voltage to the device and/or for signal transmission to the electronic circuit is present that can be secured to the housing ( ); the housing parts ( ) are joined to one another by laser welding at a joining edge ( ). The connection device ( ) is provided with a welding flange ( ), which comes to rest between the housing parts ( ) in such a way that an at least nonpositive connection of the housing parts ( ), with enclosure of the connection device ( ), can be produced.

Electrical device

In an arrangement composed of a substrate and a heat sink, the substrate is provided on a first side with at least one power component arranged on a first large-surface printed circuit trace and, on a second side opposite the power component, with a second large-surface printed circuit trace, which is connected in a thermally conductive manner to the first printed circuit trace via via holes. The substrate is mounted at the second side onto the heat sink in a thermally conductive manner, in order to achieve a good heat coupling of the substrate to the heat sink and the same time to avoid an undesirable electrical contact between the potential-carrying printed circuit traces and the heat sink. The substrate having spacer elements arranged on the second side is placed onto the heat sink and to hold it at a defined distance from the heat sink, the gap formed by the distance between the substrate and the heat sink being filled with a thermally conductive filler.

Housing for an electronic circuit

A spring element, for securing components of an electronic control device, is essentially U-shaped, with a bridge portion (16), which rests on an end (11A) of a cooling fin (11) mounted perpendicularly on a printed circuit board (13), and a pair of depending spring legs (17, 18), one of which presses against a side face (11C) of the cooling fin (11) and the other of which presses a power component (14) against a major surface (11B) of the cooling fin (11). Preferably, the spring element (15, 15A) is formed with a pair of slots (23, 24) which facilitate engagement by a pair of tongs (25, 26) of an automatic mounting device. The tongs can spread open the spring element and position it around the cooling fin (11) and power component (14) without exerting any harmful shear forces on the fin or component. Preferably, each spring leg has a convex central section, below the slot, and a concave bottom or terminal end. Optionally, the inner surface of the terminal end (21A, 22A) is formed with a claw or tooth (27, 28) for better holding.
