Description
Die Erfindung betrifft eine Anordnung zum Kühlen eines auf einer Leiterplatte angeordneten Bauelementes nach dem Oberbegriff des Anspruchs 1.The The invention relates to an arrangement for cooling a printed circuit board arranged component according to the preamble of claim 1.
Zum Kühlen eines elektrischen Bauelementes ist es bekannt, einen Kühlkörper vorzusehen, der thermisch mit dem Bauelement gekoppelt ist. Der Kühlkörper ist in der Form und Größe dem Bauelement und der abzuführenden Wärme angepasst. Zum Abführen der Wärme kann der Kühlkörper von Kühlluft umströmt sein oder vom Kühlwasser durchströmt sein. Wenn das Bauelement in einer dicht gepackten Schaltungsanordnung angeordnet ist, ist es in den meisten Fällen aus Platzgründen nicht möglich, standardisierte oder vorgefertigte Kühlkörper einzusetzen. Individuell an das Bauelement angepasste Kühlkörper sind kostenaufwendig, insbesondere wenn diese bei oberflächenmontierten Bauteilen angewendet werden sollen.To the Cool of an electrical component, it is known to provide a heat sink, which is thermally coupled to the device. The heat sink is in the shape and size of the component and the payable Heat adjusted. To the lead away the heat the cooling body can be flowed around by cooling air or from the cooling water flows through be. If the device is in a tightly packed circuit is arranged, it is in most cases not for reasons of space possible, to use standardized or prefabricated heat sinks. Individually are adapted to the device heatsink Costly, especially if these surface-mounted Components are to be applied.

Aufgabe der Erfindung ist es, eine Anordnung zum Kühlen eines auf einer Leiterplatte angeordneten elektrischen Bauelementes zu entwickeln, die eine verbesserte Kühlwirkung unterschiedlich hoher Bauelemente mittels Wärmeleitmatten ermöglicht.task The invention is an arrangement for cooling a on a circuit board arranged to develop electrical component, which improved cooling effect allows different levels of components by means of heat conductivities.
Die Aufgabe wird mit einer Anordnung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object is achieved with an arrangement which the features after Claim 1. Advantageous embodiments emerge the dependent claims.
Gemäß der Erfindung wird die Wärme aus dem Bauelement über Distanzbolzen zunächst in eine Metallplatte geführt, wobei die Metallplatte keinen direkten Kontakt zu dem Bauelement aufweist. Die Metallplatte liegt in der Höhe auf einem durchschnittlichen Niveau benachbarter Bauelemente, so dass mit einer wärmeleitenden Matte zwischen dem Bauelement und einem Kühlkörper die Wärme schließlich in den Kühlkörper überführt werden kann.According to the invention gets the heat from the device over Distance bolts first led into a metal plate, wherein the metal plate is not in direct contact with the device having. The metal plate is in height on an average Level of adjacent components, so that with a thermally conductive Mat between the device and a heat sink, the heat will eventually be transferred to the heat sink can.
Die Distanzbolzen können einen sechseckförmigen oder kreisförmigen Querschnitt besitzen und aus einem thermisch und/oder elektrisch gut leitenden Material, wie Kupfer oder Messing, bestehen. Wenn das Bauelement auf der Leiterplatte verlötet ist, dann ist es von Vorteil, dass zur Wärmeableitung mindestens eine entsprechend stark dimensionierte Leiterbahn zwischen dem Bauelement und einem wärmeleitenden Distanzbolzen vorgesehen ist. Bei Bauelementen mit Kühlfahne kann die Kühlfahne direkt mit einem Distanzbolzen thermisch verbunden sein.The Distance bolts can a hexagonal or circular Cross section and from a thermal and / or electrical good conductive material, such as copper or brass. If the component is soldered to the circuit board, then it is an advantage that for heat dissipation at least a correspondingly large-sized conductor track between the component and a thermally conductive Distance bolt is provided. For components with cooling flag can the cooling flag be thermally connected directly to a spacer bolt.
Es ist weiterhin von Vorteil, wenn zusätzlich zu den Distanzbolzen eine direkte wärmeleitende Verbindung zwischen einem zu kühlenden Bauelement und einer Metallplatte über einen wärmeleitenden elastischen Körper besteht.It is also advantageous if in addition to the spacer bolts a direct heat conducting connection between a to be cooled Component and a metal plate over a thermally conductive elastic body.
Bei Leiterplatten mit mehreren zu kühlenden Bauelementen kann die Anordnung nach Anspruch 1 mehrfach vorgesehen werden, wobei die den Bauelementen zugeordneten Metallplatten die Wärme über eine Matte auf einen gemeinsamen Kühlkörper abführen. Weil die Matte isolierend ist, treten elektrisch keine Kurzschlüsse zwischen den Bauelementen auf. Wenn die Metallplatten mit dem jeweiligen zu kühlenden Bauelement elektrisch verbunden sind, dann können die Metallplatten zusätzlich mit Strom/Spannungsabgriffselementen versehen sein, so dass elektrischen Verbindungen zu anderen Bauelementen herstellbar sind, die das gleiche Potential wie das jeweilige zu kühlende Bauelement aufweisen.In printed circuit boards having a plurality of components to be cooled, the arrangement according to claim 1 can be provided several times, wherein the metal plates associated with the components dissipate the heat via a mat on a common heat sink. Because the mat is insulating, there are no electrical short circuits between the components. When the metal plates are electrically connected to the respective component to be cooled, then the metal plates can be additionally provided with current / Spannungsabgriffselementen so that electrical connections to other components can be produced, which have the same potential as the respective component to be cooled.
Der Kühlkörper selbst kann wassergekühlt sein oder mit einen wassergekühlten Körper in Wämekontakt stehen. Zur Wärmeabführung vom Kühlkörper können auch andere Mittel wie Luft oder Peltierkühlung, zum Einsatz kommen.Of the Heat sink itself can be water cooled or with a water-cooled body in contact with the heat stand. For heat dissipation from Heatsinks can also other means such as air or Peltier cooling, are used.
