Abstract
Description
Die in elektronischen Geräten entstehende Verlustwärme muß abgeführt werden. Abhängig von der Baugröße und der Verlustleistung der Geräte kann diese ohne besondere Maßnahmen, durch Gehäuse erhöhter Wärmeleitfähigkeit oder durch besondere Maßnahmen wie Kühlkörper, Heatpipes, Luft-/Wasserkühlung etc. abgeführt werden. Die Möglichkeiten der Wärmeabfuhr werden durch weitere Bedingungen wie Berührschutz, Forderungen nach wasser-, staub- oder gasdichtigkeit eingeschränkt.The in electronic devices resulting heat loss must be removed. Dependent of the size and the Power loss of the devices can these without special measures, through housing increased thermal conductivity or by special measures such as heat sinks, heat pipes, air / water cooling etc. dissipated become. The possibilities the heat dissipation are met by additional conditions such as protection against accidental contact limited water, dust or gas tightness.
Besonders problematisch ist die Abfuhr der Verlustwärme bei elektronischen Regelgeräten in explosionsgefährdeten Bereichen. Hier unterliegen die Geräte bestimmten Schutzklassen, die einerseits z.B. mediendichtigkeit vorschreiben, zum anderen die zulässigen Oberflächentemperaturen auf sehr geringe Werte begrenzen. Hiermit wird auch die zulässige spezifische Wärmebelastung der Gehäuseoberfläche begrenzt.Especially The dissipation of the heat loss in electronic control devices in potentially explosive atmospheres is problematic Areas. Here the devices are subject to certain protection classes, which on the one hand e.g. prescribe media tightness, on the other hand the permissible surface temperatures limit to very low values. This also specifies the permissible heat stress limited the surface of the housing.
Die in elektronischen Geräten höherer Leistung auftretende Verlustleistung entsteht sowohl in der Ansteuerelektronik, wie auch in den eigentlichen Leistungshalbleitern. Während die Verlustleistung der Ansteuerelektronik über die gesamte Platine verteilt auftritt, wird die Verlustleistung der Leistungshalbleiter lokal erzeugt. Bei den üblichen Kühlmethoden wird ein einheitliches Temperaturniveau im gesamten Gehäuse angestrebt (Beisp.: PC mit Lüftern), oder die Verlustleistung der Leistungshalbleiter wirkt auf die übrige Elektronik zurück (Beisp. Leistungsverstärker mit Kühlkörpern in der Gehäusewand). Besonders nachteilig sind die üblichen Kühlmethoden, wenn die Leistungshalbleiter ein höheres Temperaturniveau ertragen, als einzelne Bauteile der Ansteuerelektronik. In diesem Fall muß die die Kühlfläche für eine sehr niedrige Temperaturdifferenz bei hoher Leistung, also sehr groß, ausgelegt werden.The in electronic devices higher Power loss occurs both in the control electronics, as in the actual power semiconductors. While the Power loss of the control electronics distributed over the entire board occurs, the power dissipation of the power semiconductors becomes local generated. With the usual cooling methods the aim is to achieve a uniform temperature level throughout the housing (Example: PC with fans), or the power dissipation of the power semiconductors affects the rest of the electronics back (Ex. Power amplifier with heat sinks in the housing wall). The usual ones are particularly disadvantageous Cooling methods if the power semiconductors a higher one Endure temperature level as individual components of the control electronics. In this case, the the cooling surface for a very low temperature difference with high performance, i.e. very large become.
Mit dieser Erfindung kann die Verlustleistung des Leistungshalbleiters zu einem großen Anteil direkt an die vom Gehäuse abgesetzte Kühlfläche übertragen werden, wobei ggf. das höhere Temperaturniveau am Leistungshalbleiter genutzt werden kann, um eine insgesamt kleinere Kühlfläche zu realisieren. Durch die Wahl eines geeigneten Abstandes zwischen Gehäuse und Kühlkörper läßt sich zudem ein Kamineffekt erzielen, welcher die Kühlung zusätzlich verbessert.With This invention can reduce the power dissipation of the power semiconductor to a big one Share directly to that of the housing transferred cooling surface be, where appropriate the higher Temperature level on the power semiconductor can be used to to realize an overall smaller cooling surface. By choosing a suitable distance between the housing and Heatsink can be achieve a chimney effect, which also improves cooling.
