Description

Spulen, die mit hoher Leistung beaufschlagt werden, müssen im allgemeinen gekühlt werden. Die Kühlung wird dann problematisch, wenn gleichzeitig eine hohe Spannungsfestigkeit gegenüber anliegenden Kühlkörpern oder weiteren Wicklungen obligatorisch ist.Coils that are subjected to high power generally have to be cooled will. Cooling becomes problematic if there is a high one at the same time Dielectric strength against adjacent heat sinks or other windings is mandatory is.

Es sind Hochleitstungsspulen bekannt, z. B. aus der US 3 041 562.There are Hochleitstungsspulen known, for. B. from US 3 041 562.

Hier wird eine in einen gut wärmeleitenden Kunststoff eingekapselte Zündspule beschrieben, die in eine Form eingesetzt, vergossen und dann entformt wird.Here an ignition coil encapsulated in a good heat-conducting plastic is described, which is inserted into a mold, potted and then demolded.

Aus der DE 32 43 392 A1 geht eine Induktions(heiz)spule für Rundmaterial hervor, die in einem Betonkörper untergebracht ist und die in einer Gummimasse eingelagert ist, um die auftretenden Wärmespannungen zu eliminieren.DE 32 43 392 A1 shows an induction (heating) coil for round material, which is housed in a concrete body and which is in a rubber mass is stored in order to eliminate the thermal stresses that occur.

Weiterhin ist bekannt, Hochleistungsspulen in einen gut leitenden Trog aus Keramik z. B. Berylliumoxid einzubringen und zu vergießen.It is also known to use high-performance coils in a highly conductive trough made of ceramic, for. B. Introduce and shed beryllium oxide.

Hierbei ergaben sich Schwierigkeiten wegen der unterschiedlichen Wärmeausdehnungskoeffizienten von Keramik und Vergußmasse. Außerdem ist der Kontakt zwischen Keramiktrog und Kühlfläche nur durch Wärmeleitpaste optimal zu dimensionieren.Difficulties arose due to the different coefficients of thermal expansion of ceramics and potting compound. In addition, the contact between ceramic trough and cooling surface can only be optimally dimensioned using thermal paste

Aufgabe der Erfindung ist es daher, eine Hochleistungsspule zu schaffen, die bei einfachen Aufgaben ausreichend gekühlt wird.The object of the invention is therefore a high-performance coil to create sufficient for simple tasks is cooled.

Es konnte nun gefunden werden, daß neuartige, spritzgußtechnisch verarbeitbare gut wärmeleitende Kunststoffe (Handelsname SARCON) die Nachteile eines Keramiktroges vermeiden. Dieser Kunststoff behält eine gewisse Elastizität (Shore-Härte A 80), so daß unter Druck sich der Trog ohne Luftspalt an die Kühlfläche anpaßt. It has now been found that novel, injection molding good heat-conductive plastics (trade name SARCON) the Avoid the disadvantages of a ceramic trough. This plastic keeps one certain elasticity (Shore hardness A 80), so that under pressure the trough without Adapts air gap to the cooling surface.  

Weiterhin hat dieser Kunststoff einen vergleichbaren 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 für Keramik ohne teure Schleifprozesse nicht erreichbar ist.Furthermore, this plastic has a comparable 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 for ceramics without expensive grinding processes is.

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