Abstract
Description
Die Erfindung bezieht sich auf ein im Oberbegriff des Patentanspruchs 1 angegebenes Lüftersystem.The The invention relates to a in the preamble of the claim 1 specified fan system.
Das dort beschriebene Lüftersystem weist jedoch den Nachteil auf, dass bei einem etwaigen Luftstau, beispielsweise hervorgerufen durch Bauelemente, dieser wiederum den durch Lüftereinheiten erzeugten Luftstrom umlenkt, was den Nachteil einer örtlichen Erwärmung und damit eine Störung von elektronischen Schaltfunktionen mit sich bringt.The there described fan system has the disadvantage, however, that in the event of For example, caused by components, this in turn that generated by fan units Airflow diverts, which has the disadvantage of local heating and thus a disturbance of electronic switching functions.
Der Erfindung liegt die Aufgabe zugrunde, ein weiteres Lüftersystem anzugeben.Of the Invention is the object of another fan system specify.
Gemäß der Erfindung wird die gestellte Aufgabe bei der Anordnung der eingangs genannten Art durch die im Patentanspruch 1 aufgeführten Merkmale gelöst.According to the invention The object is in the arrangement of the aforementioned Art solved by the features listed in claim 1.
Durch die erfindungsgemäße Maßnahme ergibt sich der Vorteil, dass der durch Lüftereinheiten unmittelbar erzeugte Luftstrom direkt in die über sie angeordneten bzw. zugeordneten Strömungskanäle, z.B. gebildet durch eine definierte Anzahl von Baugruppenschächten, eingeleitet wird.By the measure according to the invention results the advantage that the directly generated by fan units Airflow directly into the over they arranged flow channels, e.g. formed by one defined number of assembly shafts, is initiated.
Die Anordnung bringt den Vorteil mit sich, dass die Breite der Lüftereinschübe auf eine bestimmte Anzahl von Baugruppen abgestimmt ist.The Arrangement has the advantage that the width of the fan trays on a certain number of assemblies is tuned.
Die Anordnung bringt den Vorteil mit sich, dass durch die Anordnung mindestens eines Zwischenelementes ein homogener Luftkanal in Verbindung mit den beispielsweise darüber liegenden durch die Leiterplatten gebildeten Zwischenräume in der Baugruppenträgereinheit gebildet wird.The Arrangement brings with it the advantage that through the arrangement at least one intermediate element a homogeneous air duct in connection with the example above lying formed by the circuit boards spaces in the rack unit is formed.
Die Anordnung bringt den Vorteil mit sich, dass für Baugruppen mit unterschiedlicher Verlustleistung jeweils eine hierfür nötige Ventilatorleistung eingeregelt werden kann.The Arrangement brings the advantage that for assemblies with different Power loss adjusted in each case a necessary fan power can be.
Die Anordnung bringt den Vorteil mit sich, dass auf Lüftereinschübe bei einer geringeren Bestückung des Baugruppenträgers mit Baugruppen auf einen oder mehrere Lüftereinschübe verzichtet werden kann.The Arrangement has the advantage that on fan trays at a lower population of the subrack With modules on one or more fan trays can be dispensed with.
Die Anordnung bringt den weiteren Vorteil mit sich, das Bereiche mit einer Zwangsbelüftung und Bereiche mit freier Konvektion kombinierbar sind.The Arrangement brings with it the further advantage of having areas a forced ventilation and areas with free convection can be combined.
Weitere vorteilhafte Ausbildungen der Erfindung sind in den Unteransprüchen angegeben.Further advantageous embodiments of the invention are specified in the subclaims.
Weitere Besonderheiten der Erfindung werden aus der nachfolgenden näheren Erläuterung eines Ausführungsbeispiels anhand von Zeichnungen ersichtlich.Further Particular features of the invention will become apparent from the following detailed explanation an embodiment based on drawings.
