Abstract
Description
Die Erfindung betrifft eine Anordnung zum Kühlen eines auf einer Leiterplatte angeordneten Bauelementes nach dem Oberbegriff des Anspruchs 1.The invention relates to an arrangement for cooling a component arranged on a printed circuit board 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.For cooling an electrical component it is known to provide a heat sink, which is thermally coupled to the component. The heat sink is the shape and size of the component and the one to be discharged Heat adjusted. To the lead away of warmth cooling air can flow around the heat sink or from the cooling water flows through his. If the device is in a tightly packed circuit arrangement is arranged, in most cases it is not for reasons of space possible, use standardized or prefabricated heat sinks. Individually are heat sinks adapted to the component costly, especially if it is surface-mounted Components are to be applied.
Zum Kühlen von Bauelementen sind
wärmeleitende,
elektrisch isolierende Matten bekannt, die von der Bestückungsseite
her an die zu kühlenden Bauelemente

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.The object of the invention is a Cooling arrangement an electrical component arranged on a printed circuit board to develop an improved cooling effect of different levels Components using thermal mats allows.
Die Aufgabe wird mit einer Anordnung gelöst, welche die Merkmale nach Anspruch 1 aufweist. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The task comes with an arrangement solved, which has the features of claim 1. Advantageous configurations result from the subclaims.
Gemäß der Erfindung wird die Wärme aus dem Bauelement zunächst in eine Metallplatte geführt, wobei die Metallplatte keine direkten Kontakt zu den Bauelementen 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, the heat from the Component first led into a metal plate, whereby the metal plate has no direct contact with the components having. The metal plate is at an average height Level of neighboring components, so that with a thermally conductive Mat between the component and a heat sink, the heat is finally transferred to the heat sink can.
Es ist von Vorteil, wenn das Bauelement über Distanzbolzen mit der Metallplatte verbunden ist. 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.It is advantageous if the component has spacers is connected to the metal plate. The spacers can one hexagonal or circular Have cross-section and from a thermal and / or electrical well conductive material, such as copper or brass. If the component is soldered to the circuit board, then it is advantageous that for heat dissipation at least one correspondingly dimensioned conductor track between the component and a thermally conductive Spacer is provided. For components with a cooling vane can the cooling vane be thermally connected directly with a spacer.
Es ist weiterhin von Vorteil, wenn zusätzlich zu Distanzbolzen eine direkte wärmeleitende Verbindung zwischen einem zu kühlenden Bauelement und einer Metallplatte über einen wärmeleitenden elastischen Körper besteht.It is still an advantage if in addition to Spacer bolts a direct heat conductive Connection between one 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.For circuit boards with several to cooling components the arrangement according to claim 1 can be provided several times, wherein the metal plates assigned to the components transfer the heat via a Remove the mat onto a common heat sink. Because the mat is insulating, there are no electrical short circuits between the components. If the metal plates with the respective to be cooled Component are electrically connected, then the metal plates can additionally with current / voltage tap elements be provided so that electrical connections to other components are producible that have the same potential as the respective one cooling Have component.
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.The heat sink itself can be water-cooled or with a water-cooled body in thermal contact stand. For heat dissipation from Heatsinks can also other means such as air or Peltier cooling can be used.
