Abstract

A high-power coil having a high dielectric strength while at the same time having good cooling is described, which manages without the conventional ceramic trough as a result of the use of a plastic having good thermal conductivity and the same coefficient of expansion as polyamide, so that the conventional potting can be omitted.

Description

Spulen, die mit hoher Leistung beaufschlagt werden, müssen im allge­ meinen gekühlt werden. Die Kühlung wird dann problematisch, wenn gleichzeitig eine hohe Spannungsfestigkeit gegenüber anliegenden Kühl­ körpern oder weiteren Wicklungen obligatorisch ist.Coils that are subjected to high power must generally mean to be chilled. Cooling becomes problematic when at the same time a high dielectric strength compared to adjacent cooling body or other windings is mandatory.

Nach dem Stand der Technik wurde das Problem in der Weise gelöst, daß die Spule in einen gut wärmeleitenden Trog aus Keramik, z.B. Berylliumoxid eingebettet und dann eingegossen wurde. Hierbei erga­ ben sich Schwierigkeiten wegen der unterschiedlichen Wärmeausdehnungs­ koeffizienten von Keramik und Vergußmasse. Außerdem ist der Kontakt zwischen Keramiktrog und Kühlfläche nur durch Wärmeleitpaste optimal zu dimensionieren. Es konnte nun gefunden werden, daß neuartige, spritzgußtechnisch verarbeitbare gut wärmeleitende Kunststoffe (Handels­ name SARCON) die Nachteile eines Keramiktroges absolut vermeiden. Dieser Kunststoff behält eine gewisse Elastizität (Shore-Härte A 80), so daß unter einem gewissen Druck sich der Trog ohne Luftspalt an die Kühlfläche anpaßt.According to the prior art, the problem was solved in such a way that the coil was embedded in a heat-conducting trough made of ceramic, for example beryllium oxide, and then cast in. Difficulties arose due to the different thermal expansion coefficients of ceramic and sealing compound. In addition, the contact between the ceramic trough and the cooling surface can only be optimally dimensioned using thermal paste. It has now been found that novel, thermally conductive plastics (trade name SARCON) which can be processed by injection molding absolutely avoid the disadvantages of a ceramic trough. This plastic retains a certain elasticity (Shore hardness A 80), so that under a certain pressure the trough adapts to the cooling surface without an air gap.

Weiterhin hat dieser Kunststoff den gleichen Wärmeausdehnungskoeffi­ zienten wie beispielsweise PA (Polyamid), so daß ein einfacher Stülp­ deckel den Spulentrog umschließen kann, d.h. der aufwendige Verguß­ prozeß kann entfallen. Durch die Herstellbarkeit des Troges und des Stülpdeckels in Spritzgußtechnik ist eine hohe Paßgenauigkeit vorge­ geben, die mit Keramik ohne teure Schleifprozesse nicht erreichbar ist.Furthermore, this plastic has the same coefficient of thermal expansion such as PA (polyamide), so that a simple slip cover can enclose the coil trough, i.e. the elaborate potting process can be omitted. Due to the manufacturability of the trough and the Slip-on lid in injection molding technology is a high fit accuracy that cannot be achieved with ceramics without expensive grinding processes is.

Die Zeichnungen stellen ein Ausführungsbeispiel dar, wobei an sich die Konfiguration eher zufällig ist. Es ist jede andere Ausgestaltung von Hochleistungsspulen denkbar, die das aufgezeigte Prinzip beinhal­ ten.The drawings represent an embodiment, in itself the configuration is rather random. It is any other configuration of high-performance coils conceivable, which include the principle shown ten.
