Description

Die Erfindung betrifft die Kühlung von Hochleistungsnetzteilen und Hochenergiespulen, wie z. B. bei Hochleistungsschaltnetzteilen, um die nachteiligen Kupferverluste ohne Ölwannen u. dg. rasch und kostengünstig abführen zu können.The invention relates to the cooling of high-performance power supplies and high-energy coils, such as e.g. B. in high-performance switching power supplies to the disadvantageous copper losses without oil sumps u. dg. to be able to transfer quickly and inexpensively.

Solche Hochenergiespulen bzw. Hochleistungsnetzteile müssen große Mengen elektrischer Energie transportieren und erleiden unvermeidliche Energieverluste. Aus solchen Verlusten resultiert auch das erforderliche Bauvolumen, um eine zu hohe Erhitzung zu vermeiden.Such high-energy coils or high-performance power supplies need large amounts of electrical Transport and suffer inevitable energy losses. From such losses this also results in the required construction volume in order to avoid excessive heating.

Es ist bekannt, daß zur Erzielung der Ableitung der Wärmeverluste von Hochenergiespulen wie z. B. für Schaltnetzteile auch leitfähiges Rohrmaterial eingesetzt wird, meist Kupfer, um im Innern eine Kühlflüssigkeit aufzunehmen. Bei höheren Frequenzen und bei geringen Querschnitten ist dies allerdings nicht zielführend.It is known that to achieve the dissipation of heat losses from high-energy coils such as B. for switching power supplies also conductive pipe material is used, usually copper absorb a coolant inside. At higher frequencies and at low ones However, this does not lead to cross sections.

Daher müssen größere Bauvolumen bei Luftkühlung gewählt werden als notwendig oder aufwändige Ölbäder mit erheblichen Mehrkosten.For this reason, larger construction volumes for air cooling must be selected than necessary or complex oil baths with considerable additional costs.

Der Erfindung liegt die Aufgabe zugrunde, die Wärmeverluste aus elektrischen Spulen, wie z. B. bei Schaltnetzteilen oder Hochleistungstransformatoren besonders wirtschaftlich und kostengünstig abzuführen.The invention has for its object the heat loss from electrical coils, such as e.g. B. in switching power supplies or high-performance transformers particularly economical and dissipate inexpensively.

Diese Aufgabe wird erfindungsgemäß dadurch gelöst, daß die Windungen von elektrischen Spulen als Rohre ausführt sind, in deren Innerem sich eine Flüssigkeit befindet, die bereits bei niederen Temperaturen verdampft und somit durch Anwendung des Verdampfungs­ prinzips, das ein ganz vorzüglicher Wärmeleiter ist - weit ergiebiger als z. B. Kupfer - diese abgenommene Wärme an einen Kondensator, auch Kühler genannt, weitergibt, in dem das Gas aus der Dampfphase heraus wieder kondensiert und dem Kreislauf als Flüssigkeit wieder zugeführt wird. Dieses Verfahren ist in ähnlicher Weise als Heat-pipe bekannt geworden als mechanische Kühlung für die Kühlung von Halbleitern in Leistungsverstärkern.This object is achieved in that the turns of electrical Coils are designed as tubes, inside which there is a liquid that is already evaporates at low temperatures and thus by using the evaporation principle, which is a very excellent heat conductor - far more productive than z. B. copper - this passes the removed heat to a condenser, also called a cooler, in which the Gas condenses out of the vapor phase and the circuit as a liquid is fed again. This process is similarly known as a heat pipe become mechanical cooling for cooling semiconductors in power amplifiers.

Claims (1)

Kühlsystem von elektrischen Spulen, dadurch gekennzeichnet, daß die Windungen oder Teile der Windungen hohl ausgeführt sind und im Innern dieses Rohrsystems sich eine bei niederer Temperatur verdampfende Flüssigkeit befindet, die an einem externen Kühler wieder kondensiert, wenn sie durch die Erhitzung der Spule verdampft ist. Die verdampfte Flüssigkeit kann über einen Isolator ausgekoppelt und dem Kühler zugeführt werden. Die verwendete Flüssigkeit sollte nicht stromleitend sein, um elektrolytische Probleme wie bei der Wasserkühlung zu vermeiden, dasselbe gilt für die gasförmige Phase.Cooling system for electrical coils, characterized in that the windings or parts of the windings are hollow and in the interior of this pipe system there is a liquid which evaporates at low temperature and which condenses again on an external cooler when it has evaporated due to the heating of the coil. The evaporated liquid can be extracted via an isolator and fed to the cooler. The liquid used should not be electrically conductive to avoid electrolytic problems like water cooling, the same applies to the gaseous phase.
