Vorrichtung zum hochspannungsfesten und gut wärmeleitenden Einbau von Halbleiter-BauelementenDevice for high-voltage-resistant and highly thermally conductive installation of semiconductor components
Die Neuerung betrifft eine Vorrichtung zum hochspannungsfesten und gut wärmeleitenden Einbau von Halbleiterbauelementen, insbesondere mit Flanschgehäuse, in elektrische Baugruppen.The innovation relates to a device for high-voltage-resistant and highly thermally conductive installation of semiconductor components, in particular with flange housing, in electrical assemblies.
Beim Einbau von Halbleiterbauelementen stellt sich immer wieder das Problem, die im Bauelement anfallende Verlustwär&e abzuleiten, um damit eine überhöhte Temperatur im Bauteileraum zu verhindern. Die hohen Temperaturen insbesondere von aktiven Bauelementen hoher Leistungsabgabe können zum einen eine Zerstörung des betreffenden Bauelements selbst bewirken sowie auc_ eine V/äi^mebeeinflussung benachbarter Bauelemente und damit eine Funktionsstörung der gesamten Baugruppe. Zum Zweck der Wärmeableitung sind daher beispielsweise wärmeableitende Mittel vorgesehen, die mit dem Halbleiterbauelement in guter thermischer Verbindung stehen oder bei Halbleiterbauelementen mit Flanschgehäusen ist das Flanschgehäuse mit einer wärmeableitenden Wandung des Gehäuses gut wärmeleitend verbunden. Bei derartigen Halbleiterbauelementen steht also eine gute Ableitung der im Bauelement anfallenden Verlustwärme im Vordergrund. Soll der Einbau der Bauelemente zudem auch mit hoher Spannungsfestigkeit erfolgen, also auch eine hohe elektrische Isolation zur Montagefläche gegeben sein, so führt dies nach der herkömmlichen Technik zu recht aufwendigen konstruktiven Lösungen zum Erhalt der notwendigen Isolationsstrecken. When installing semiconductor components, the problem arises again and again of dissipating the heat loss that occurs in the component, in order to prevent an excessive temperature in the component area. The high temperatures of active components in particular high power output can on the one hand cause destruction of the relevant component itself and also a Influence of neighboring components and thus a malfunction the entire assembly. For the purpose of heat dissipation, heat dissipating means are therefore provided, for example, which are in good thermal contact with the semiconductor component or, in the case of semiconductor components, with flange housings the flange housing is connected to a heat-dissipating wall of the housing with good thermal conductivity. With such semiconductor components a good dissipation of the heat loss occurring in the component is therefore in the foreground. Should the installation of the components also take place with high dielectric strength, so there is also a high electrical insulation to the mounting surface according to the conventional technology, this leads to very complex constructive solutions for maintaining the necessary isolation distances.
