Description

Stand der Technik Die Erfindung geht von einem elektronischen Steuergerät nach der Gattung des Anspruchs 1 aus. Bei einem elektronischen Regler für Drehstromgeneratoren von Kraft fahrzeugen ist das Gehäuseinnere mit einer weichen Silikonharzmasse ausgefüllt. Das ist bei verhältnismäßig großem Gehäuseinneren unwirtschaftlich und somit von Nachteil.PRIOR ART The invention is based on an electronic control device according to the preamble of claim 1. In the case of an electronic controller for three-phase generators of motor vehicles, the interior of the housing is filled with a soft silicone resin compound. In the case of a relatively large interior, this is uneconomical and therefore of Disadvantage.

Auch harte Epoxidharzmassen sind bei elektronischen Reglern als Vergußmasse bekannt. Sie haben den Nachteil, daß bei Temperatur-Wechselbeanspruchung Schäden an den Lötstellen zwischen Bauelementen und Leiterbahnen entstehen bei den Stoffen unterschiedlicher Ausdehnungskoeffizienten. Auch Gehäuse mit einzelnen Kühlmitteldurchgängen wurden schon vorgeschlagen. Als Kühlmittel diente jedoch Luft. Dabei ist von Nachteil, daß die Luft nur bei verhältnismäßig niedriger Umgebungstemperatur des Steuergeräts wirksam kühlen kann.Hard epoxy resin compounds are also used as potting compounds in electronic controllers known. They have the disadvantage that damage is caused by alternating temperatures at the soldering points between components and conductor tracks arise with the substances different expansion coefficients. Also housings with individual coolant passages have already been proposed. However, air was used as the coolant. The disadvantage here is that the air is only available when the ambient temperature of the control unit is relatively low can effectively cool.

Vorteile der Erfindung Das erfindungsgemäße elektronische Steuergerät mit den kennzeichnenden Merkmalen des Anspruchs 1 hat demgegenüber den Vorteil, daß ein Steg des Gehäuses sowohl die Kühlmitteldurchgänge enthält als auch die Bauelemente der Leistungsstufe trägt. Dabei eignet sich als bereits vorhandenes Kühlmittel der Kraftstoff des Fahrzeugs mit relativ niedriger Temperatur. Außerdem wirkt der das Gehäuseinnere ausfüllende Schaumstoff wärmeisolierend. Er verträgt darüber hinaus die verhältnismäßig hohen Umgebungstemperaturen des Motorblocks und wirkt schwingungsdämpfend, so daß die von Motor und Straße auf das Steuergerät übertragenen Stöße weitgehend absorbiert werden.Advantages of the Invention The electronic control device according to the invention with the characterizing features of claim 1 has the advantage that a web of the housing contains both the coolant passages and the components the performance level carries. The is suitable as an existing coolant Vehicle fuel at a relatively low temperature. Besides, that works The inside of the housing is filled with insulating foam. He also tolerates the relatively high ambient temperatures of the engine block and has a vibration-damping effect, so that the shocks transmitted from the engine and road to the control unit are largely be absorbed.

Durch die in den Unteransprüchen aufgeführten Maßnahmen sind vorteilhafte Weiterbildungen des im Anspruch 1 angegebenen Steuergeräts möglich. Besonders vorteilhaft ist, daß die Leistungsstufe weitgehend von Kühlmitteldurchgängen umgeben ist und darüber hinaus noch Kühlrippen des Stegs in die Nähe der Bauelemente der Steuerelektronik ragen. Somit wirkt der von Kühlmittel durchflossene Steg auch als Kühlspeicher vorallem bei kurzzeitiger Erhöhung der das Steuergerät umgebenden Temperatur, das heißt, bei Stauwärme. Dadurch wird eine Erhöhung der Temperatur im Steuergerät auf unerwünschte Werte verhindert, die sowohl durch die von der Leistungsstufe abgegebene Verlustwärme als auch von der Umgebungstemperatur des Motorblocks, an welchem das Steuergerät angebaut ist, herrührt.The measures listed in the subclaims are advantageous Further developments of the control device specified in claim 1 are possible. Particularly beneficial is that the power stage is largely surrounded by coolant passages and In addition, there are cooling fins of the web in the vicinity of the components of the control electronics protrude. Thus, the web through which coolant flows also acts primarily as a cooling reservoir in the event of a brief increase in the temperature surrounding the control unit, i.e. with accumulated heat. This causes an increase in the temperature in the control unit to be undesirable Values prevented both by the heat loss given off by the power stage as well as the ambient temperature of the engine block on which the control unit is connected is grown, originates.
