Description

Die Erfindung betrifft ein Lüftermodul mit einem feststehenden Lüfterelement und einem drehbar gelagerten beweglichen Lüfterelement, daß von dem feststehenden Lüfterelement teilweise umschlossen ist, zur Erzeugung eines Luftstroms, wobei das bewegliche Lüfterelement durch einen Elektromotor in Rotation versetzbar ist.The invention relates to a fan module with a fixed Fan element and a rotatably mounted movable Fan element that partially from the fixed fan element is enclosed, for generating an air flow, wherein the movable fan element in rotation by an electric motor is relocatable.

Solche Lüftermodule werden in elektrischen Geräte jeglicher Art eingesetzt. Vor allem Rechnersysteme benötigen zur Kühlung derartige Lüftermodule, um eine Überhitzung der Netzteilkomponenten und der Prozessoren zu verhindern. Ein Ausfall der Lüfter führt unweigerlich zu einer Überhitzung des Geräts und verursacht unter Umständen irreparable Schäden.Such fan modules are used in electrical devices Kind used. Computer systems in particular require cooling such fan modules to prevent the power supply components from overheating and to prevent the processors. An outage the fan will inevitably overheat the Device and may cause irreparable damage.

In der Regel ist eine Störung an einem Lüftermodul vor dem totalen Ausfall erkennbar und das Lüftermodul kann rechtzeitig ausgetauscht werden. Dies ist allerdings relativ aufwendig, da die Lüftermodule fest eingebaut und verkabelt sind. Auf jeden Fall stellt der Austausch eines Lüftermoduls einen erheblichen Eingriff in das System dar, so daß das Gerät abgeschaltet werden muß. Bei großen Computersystemen, beispielsweise Servern, ist ein durchgehender Betrieb jedoch angestrebt oder erforderlich. Zwar sind bei derartigen Rechnersystemen in der Regel mehrere Lüftermodule vorgesehen, die gemeinsam die Kühlung bewirken, so daß der Ausfall eines einzelnen Lüftermoduls nicht zum Totalausfall der Kühlung führt, aber trotzdem muß das defekte Lüftermodul möglichst schnell ausgetauscht werden, was zur Notwendigkeit der Abschaltung des gesamten Rechners führt.There is usually a fault in a fan module in front of the total failure recognizable and the fan module can be on time be replaced. However, this is relatively complex, because the fan modules are permanently installed and wired. In any case, the replacement of a fan module is a problem significant interference in the system, so that the device is turned off must become. For large computer systems, for example Servers, however, continuous operation is desirable or required. Although with such computer systems usually several fan modules provided that together cause the cooling, so that the failure of an individual Fan module does not lead to total cooling failure, but still the defective fan module must be as fast as possible be exchanged, resulting in the need for shutdown of the entire computer.

Aufgabe der Erfindung ist es daher, ein Lüftermodul vorzuschlagen, das auch beim laufenden Betrieb des Rechner schnell ausgetauscht werden kann. Dabei darf der Raumbedarf aber nicht wesentlich größer sein als bei Lüftermodulen nach dem Stand der Technik.The object of the invention is therefore to propose a fan module, this is fast even when the computer is running can be exchanged. The space requirement is allowed not be significantly larger than with fan modules after State of the art.

Diese Aufgabe wird erfindungsgemäß durch ein Lüftermodul der eingangs genannten Art gelöst, das dadurch gekennzeichnet ist, daß an einer äußeren Seitenfläche des feststehenden Lüfterelementes Kontaktflächen angeordnet sind zur Zuführung einer Betriebsspannung zu dem Elektromotor.This object is achieved by a fan module solved type mentioned, characterized in that is that on an outer side surface of the fixed fan element Contact surfaces are arranged for feeding one Operating voltage to the electric motor.

Die erfindungsgemäße Ausgestaltung eines Lüftermodules ermöglicht, daß dieses durch Stecken in ein dafür vorgesehenes Lüftergehäuse befestigt und angeschlossen werden kann. Dadurch ist ein Tauschen dieser Komponente schnell und unkompliziert möglich. Die Kontaktflächen an der Seitenfläche benötigen sehr wenig Raum, so daß diese Lösung auch bei volumenkritischen Anwendungen realisiert werden kann. Ein wesentlicher Gesichtspunkt ist, daß neben der Einsteckmöglichkeit auch gleichzeitig die elektrische Verbindung zum Antrieb des Lüfters hergestellt wird und so eine manuelle Verkabelung entfällt. Gegenüber Steckkontakten ist dies eine kostengünstige Lösung, die zudem Vorteile im Platzbedarf hat.The design of a fan module according to the invention enables that this by plugging into a designated one Fan housing can be attached and connected. Thereby is a quick and easy replacement of this component possible. The contact surfaces on the side surface need very little space, so that this solution even for volume critical Applications can be realized. An essential one The point of view is that in addition to the possibility of insertion also the electrical connection to the drive of the Fan is manufactured and so a manual wiring eliminated. Compared to plug contacts, this is an inexpensive one Solution that also has advantages in terms of space.

In einer vorteilhaften Ausgestaltung der Erfindung ist im Bereich der Seitenfläche des feststehenden Lüfterelementes ein Rastmittel oder ein Klemmittel zur mechanischen Befestigung des Lüftermoduls in einem Lüftergehäuse, in das das Lüftermodul eingesetzt ist, vorgesehen. Dadurch ist ein sicherer Halt gewährleistet.In an advantageous embodiment of the invention is in the range the side surface of the fixed fan element Latching means or a clamping means for mechanical fastening of the fan module in a fan housing in which the fan module is used, provided. This ensures a secure hold guaranteed.

In einem Lüftergehäuse, in das die erfindungsgemäßen Lüftermodule einsetzbar sind, sind Feder- oder Schleifkontakte derart angeordnet, daß im eingesteckten Zustand der Lüftermodule die Feder- beziehungsweise Schleifkontakte mit den Kontaktflächen der Lüftermodule zusammenwirken. In einer vorteilhafte Anordnung insbesondere für große Rechnersysteme sind Feder- beziehungsweise Schleifkontakte für mehrere Lüftermodule auf einer gemeinsamen Leiterplatte angeordnet. In a fan housing, in which the fan modules according to the invention are used, spring or sliding contacts are such arranged that in the inserted state of the fan modules the spring or sliding contacts with the contact surfaces of the fan modules interact. In an advantageous Arrangement especially for large computer systems are spring or sliding contacts for several fan modules arranged on a common circuit board.

In Figur 1 ist ein Lüftermodul 10 gemäß der Erfindung dargestellt. Es weist ein feststehendes Lüfterelement 1 und ein drehbar gelagertes bewegliches Lüfterelement 2 auf. Dieses besitzt Lüfterflügel 3, die bei Drehung des beweglichen Lüfterelementes 2 einen Luftstrom erzeugen. An einer äußeren Seitenfläche 4 des feststehenden Lüfterelementes 1 sind Kontaktflächen 5 angeordnet. Diese dienen der Zuführung der Betriebsspannung für den Elektromotor, der das bewegliche Lüfterelement antreibt. Daneben können über diese Kontaktflächen 5 auch Informationen beispielsweise über die Drehzahl des Lüfters übertragen werden. Darüber hinaus ist ein Rastelement, im Ausführungsbeispiel von der Figur 1 eine Federzunge 6, ausgebildet, um das Lüftermodul in einem entsprechend geformten Lüftergehäuse zu verrasten. Zudem besitzt das Lüftermodul eine Zustands-LED 7, anhand derer erkennbar ist, ob das Lüftermodul ordnungsgemäß arbeitet, oder ob ein anormaler Betriebszustand vorliegt. 1 shows a fan module 10 according to the invention. It has a fixed fan element 1 and rotatably mounted movable fan element 2. This has fan blades 3, which when the movable fan element rotates 2 generate an air flow. On an outside Side surface 4 of the fixed fan element 1 are contact surfaces 5 arranged. These serve to supply the operating voltage for the electric motor, which is the movable fan element drives. You can also use these contact areas 5 also information, for example about the speed of the Fan are transmitted. In addition, there is a locking element in the embodiment of Figure 1 a spring tongue 6, designed to fit the fan module in a correspondingly shaped Lock the fan housing. In addition, the fan module has a status LED 7, by means of which it can be seen whether the Fan module is working properly, or whether an abnormal operating condition is present.

In der Figur 2 sind mehrere erfindungsgemäße Lüftermodule 10 in ein Lüftergehäuse 9 eingebaut. In der dargestellten Konfiguration sind drei Lüftermodule in zwei Reihen angeordnet, wobei in der einen Reihe 11 zwei Lüftermodule 10 hintereinander geschaltet sind und in der anderen Reihe 12 nur ein Lüftermodul vorgesehen ist. In der Figur 2 nicht dargestellt ist ein Gehäusedeckel, durch das Lüftergehäuse geschlossen werden kann und der gleichzeitig die Lüftermodule in ihrer Lage fixiert. Rastmittel 6 an den einzelnen Lüftermodulen 10 sind so entbehrtlich.FIG. 2 shows several fan modules 10 according to the invention installed in a fan housing 9. In the configuration shown three fan modules are arranged in two rows, wherein in one row 11 two fan modules 10 in a row are switched and in the other row 12 only one fan module is provided. Not shown in Figure 2 a housing cover that closes the fan housing can and at the same time fixes the fan modules in their position. Latching means 6 on the individual fan modules 10 are like this entbehrtlich.

Zwischen den beiden Reihen 11 und 12 ist eine Trennwand 13 vorgesehen, die gleichzeitig eine Leiterplatte zur Befestigung von Federkontakten bildet. Die Federkontakte sind dafür vorgesehen, mit den Kontaktflächen 5 eingesteckter Lüftermodule 10 eine elektrische Verbindung zu bilden. An den der Leiterplatte 13 gegenüberliegenden Gehäusewandungen sind in einer günstigen Ausführung weitere Federelemente vorgesehen, die eine Kraft auf die Lüftermodule derart ausüben, daß die Kontaktflächen 5 und die entsprechenden Feder- oder Schleifkontakte aufeinandergepreßt werden.There is a partition 13 between the two rows 11 and 12 provided that at the same time a circuit board for attachment of spring contacts. The spring contacts are for that provided with the contact surfaces 5 inserted fan modules 10 to form an electrical connection. To the the Printed circuit board 13 opposite housing walls are in a low-cost version provided further spring elements, which exert a force on the fan modules such that the Contact surfaces 5 and the corresponding spring or sliding contacts be pressed together.

In jedem der Lüftermodule 10 ist eine Zustands-LED 7 vorgesehen. Außerdem wird über die Kontaktflächen 5 die Information über den Betriebszustand der Lüftermodule 10 an eine auf einem Rechner befindliche Steuerelektronik übertragen. Wenn dort ein Fehler gemeldet wird, kann ein Servicetechniker mit einem Blick auf die installierten Lüftermodule 10 erkennen, welches der Lüftermodule 10 defekt ist. Vorteilhaft ist, daß die gleichen Lüftermodule auf beiden Seiten des Lüftergehäuses 9 eingesetzt werden können, da sie drehsymmetrisch sind.A status LED 7 is provided in each of the fan modules 10. In addition, the information is via the contact surfaces 5 via the operating state of the fan modules 10 to one on one Transfer control electronics located computer. If a service technician can report an error there recognize at a glance at the installed fan modules 10, which of the fan modules 10 is defective. It is advantageous that the same fan modules on both sides of the fan housing 9 can be used because they are rotationally symmetrical.

Aufgrund der schnellen und einfachen Austauschbarkeit der Lüftermodule 10 kann dies im laufenden Betrieb geschehen, die Lüftermodule 10 sind also "Hot-Plug-fähig". Da die beschriebenen Kontakte sehr platzsparend sind, führt die erfindungsgemäße Ausgestaltung mit ihren Vorteilen dennoch nicht zu einer Vergrößerung des Bauvolumens des Lüftergehäuses 9.Because of the quick and easy interchangeability of the Fan modules 10 can do this during operation, the Fan modules 10 are therefore "hot-pluggable". Because the described Contacts are very space-saving, leads the invention Design with its advantages, however, not one Expansion of the construction volume of the fan housing 9.

In der Figur 3 ist ein Lüftermodul 20 dargestellt, bei dem die Ausführung von Kontaktflächen 22 im Detail sichtbar ist. Die Kontaktflächen 22, die Anschlüsse für die Spannungsversorgung und zur Signalauswertung bereitstellen, sind in Gruppen von je 2 x 3 Einzelflächen angeordnet und auf einer Leiterplatte 21 angebracht. Auf der Rückseite der Leiterplatte 21 befinden sich, was in der Figur aber nicht erkennbar ist, Steckverbinder zum Anschluß eines Lüftermotors und gegebenenfalls einer Zustandsanzeige an der Leiterplatte und somit den Kontaktflächen. Die Leiterplatte 21 selber ist durch Bleche 23 gehalten, wobei zur Befestigung natürlich auch viele andere Möglichkeiten denkbar sind.3 shows a fan module 20 in which the execution of contact surfaces 22 is visible in detail. The contact surfaces 22, the connections for the voltage supply and provide for signal evaluation are in groups of 2 x 3 individual areas arranged and on a circuit board 21 attached. On the back of the circuit board 21 are located, which cannot be seen in the figure, Connector for connecting a fan motor and, if necessary a status display on the circuit board and thus the Contact surfaces. The circuit board 21 itself is through sheets 23 held, but of course many others for attachment Possibilities are conceivable.

In der Figur 4 ist eine zweite Ausführungsform eines erfindungsgemäßen Lüftermoduls dargestellt. Im Unterschied zum Ausführungsbeispiel von Figur 3 ist nicht eine Kontaktflächen tragende Leiterplatte vorgesehen, wobei die Leiterplatte mit Hilfe von Blechen an dem feststehenden Lüfterelement befestigt ist, sondern es ist ein Kontaktstiftclip 42 vorgesehen, der auf das feststehende Lüfterelement 1 aufgesteckt ist. Der Kontaktstiftclip ist in einer bevorzugten Ausführung als Kunststoffspritzteil ausgeführt, wodurch die Herstellung einfach und kostengünstig ist. Ein weiterer Vorteil besteht darin, daß die Abmessungen der Lüftermodule mit aufgesteckten Kontaktstiftclipsen 42 nur geringfügig größer sind als die der Lüftermodule ohne Kontaktstiftclipse.FIG. 4 shows a second embodiment of an inventive one Fan module shown. In contrast to The embodiment of Figure 3 is not a contact area load-bearing circuit board provided, the circuit board with With the help of sheets attached to the fixed fan element but a contact pin clip 42 is provided, which is attached to the fixed fan element 1. The Contact pin clip is in a preferred embodiment as Plastic injection molded part, making it easy to manufacture and is inexpensive. Another advantage is that the dimensions of the fan modules with attached Contact pin clips 42 are only slightly larger than that of the fan modules without contact pin clips.

Der Kontaktstiftclip trägt angefederte Kontaktstifte 41. Diese Kontaktstifte 41 ermöglichen über einen weiten Toleranzbereich eine sichere elektrische Kontaktierung des Lüftermoduls. Der Federweg der Kontaktstifte 41 ist verhältnismäßig groß, so daß auch bei großen Toleranzen des Lüftergehäuses und erschwerten Betriebsbedingungen (z. B. Vibrationen) eine sichere Kontaktierung sichergestellt ist. Die Kontaktstifte sind auf dem Kontaktstiftclip 42 so angeordnet, daß sie über einen Steckverbinder mit dem Lüftermotor verbunden werden können.The contact pin clip carries spring-loaded contact pins 41. These Contact pins 41 enable a wide tolerance range reliable electrical contacting of the fan module. The travel of the contact pins 41 is proportional large, so that even with large tolerances of the fan housing and difficult operating conditions (e.g. vibrations) secure contacting is ensured. The contact pins are arranged on the pin clip 42 so that they over a connector can be connected to the fan motor can.

Durch die Kontaktstiftclipse 42 ist die Montage erfindungsgemäßer Lüftermodule sehr schnell und einfach. Nach dem Herstellen der Steckverbindung zu den Kontaktstiften 41 muß nur noch der Kontaktstiftclip auf das feststehende Lüfterelement 1 aufgesteckt werden.Due to the contact pin clips 42, the assembly according to the invention Fan modules very quick and easy. After making the plug connection to the contact pins 41 only has to the contact pin clip on the fixed fan element 1 can be attached.

In der dargestellten vorteilhaften Ausführung ist der Kontaktstiftclip 42 zusätzlich mit zwei federnden Führungs- und Rastelementen 43 ausgestattet, die rechtwinklig zu einem mittleren Abschnitt des Kontaktklips angeordnet sind und sich damit auf die Seitenflächen des Lüftermoduls erstrecken. Die Führungs- und Rastelemente übernehmen die Führung des Lüftermoduls beim Einführen in ein entsprechendes Lüftergehäuse 44. In der vollständig eingeschobenen Position wird mit Hilfe entsprechender Rastelemente des Lüftergehäuses ein Verrasten ermöglicht, was eben besonders einfach dadurch bewerkstelligt ist, daß die Rastelemente 43 federnd ausgeführt sind.In the advantageous embodiment shown, the contact pin clip 42 additionally with two resilient guide and Locking elements 43 equipped at right angles to one middle section of the contact clip are arranged and themselves thus extend to the side surfaces of the fan module. The Guide and locking elements take over the leadership of the fan module when inserted into a corresponding fan housing 44. In the fully retracted position, use corresponding locking elements of the fan housing enables what is particularly easy to do is that the locking elements 43 are resilient.

Zusätzlich können Maßnahmen vorgesehen werden, um die Verrastung der Kontaktstiftclipse mit der Wandung des Lüftergehäuses 44 wieder zu lösen. Diese sind in Figur 4 aber nicht dargestellt.In addition, measures can be taken to secure the locking the contact pin clip with the wall of the fan housing 44 to solve again. However, these are not shown in FIG. 4.

In Figur 5 ist die vollständige Anordnung aus zwei Lüftermodulen gemäß Figur 4 und einen Lüftergehäusen 44 dargestellt. Demnach werden die Lüftermodule 40 so in das Gehäuse 44 eingeschoben, daß sich die angefederten Kontaktstifte auf der Unterseite befinden und im Gehäuse mit entsprechenden Gegenkontaktflächen auf einer Leiterplatte 46 zusammenwirken. Auf der Leiterplatte 46 können dann die entsprechenden Anschlüsse für die Ansteuerung und eventuell Überwachung der Lüftermodule 40 angeordnet werden, wobei hier die Funktionen möglich sind, die bereits anhand der Figuren 1 bis 3 beschrieben worden sind.In Figure 5 is the complete arrangement of two fan modules 4 and a fan housing 44 shown. Accordingly, the fan modules 40 are inserted into the housing 44 that the spring-loaded contact pins on the Bottom are and in the housing with corresponding mating contact surfaces cooperate on a circuit board 46. On the circuit board 46 can then the corresponding connections for controlling and possibly monitoring the fan modules 40 are arranged, the functions being possible here which have already been described with reference to FIGS. 1 to 3 are.

Im Gegensatz zu den Darstellungen von Figur 1 und Figur 2 befinden sich im Ausführungsbeispiel der Figuren 4 und 5 keine Zustandsanzeigen an den Lüftermodulen 40 selber. Stattdessen sind Zustandsanzeigen auf der Leiterplatte 46 in dem Gehäuse 44 vorgesehen. Da die Leiterplatte 46 von der Oberseite des Gehäuses 44 her nicht eingesehen werden kann, sind die Zustandsanzeigen über Lichtwellenleiter 45 nach oben geführt, so daß an der Oberseite des Gehäuses der Betriebszustand der eingesetzten Lüftermodule 40 abgelesen werden kann.In contrast to the representations of Figure 1 and Figure 2 none in the exemplary embodiment of FIGS. 4 and 5 Status displays on the fan modules 40 themselves. Instead are status indicators on the circuit board 46 in the housing 44 provided. Since the circuit board 46 from the top of the The housing 44 cannot be viewed here, the status indicators led upwards via optical waveguide 45, so that at the top of the housing the operating state of the used fan modules 40 can be read.

An der Seitenwand des Lüftergehäuses 44 sind Anprägungen 47 vorgesehen, die sicherstellen, daß die Lüftermodule 40 in einer ordnungsgemäßen Positionierung in das Gehäuse 44 eingesetzt werden.There are impressions 47 on the side wall of the fan housing 44 provided that ensure that the fan modules 40 in a properly positioned in the housing 44 become.
