Definitions
- the invention relates to a fan with at least one motor and at least one fan wheel that can be rotated about an axis of rotation and a multi-part fan housing with a multifunctional housing cover.
- the invention is therefore based on the object of providing a fan with a fan housing that has a number of functions and technically interacts with components that are necessary for the drive.
- a fan is proposed with at least one motor and at least one fan wheel that can be rotated about an axis of rotation and a multi-part fan housing.
- the fan housing forms a flow channel in which the at least one fan wheel is arranged.
- the fan housing has at least a first axial part and a second axial part, which are arranged relative to one another as viewed in the axial direction along the axis of rotation.
- the fan also includes at least one housing cover, which is arranged on an outer lateral surface of the fan housing and connects the first axial part and the second axial part to one another.
- the at least one housing cover also forms a receiving space with the outer lateral surface of the fan housing, in which a printed circuit board with motor electronics for the motor is arranged.
- the multifunctional housing cover interacts with the axial parts of the fan housing by connecting the two axial parts and thus stabilizing the overall construction.
- the accommodation space formed by the housing cover enables the printed circuit board with the motor electronics to be arranged outside of the flow of the fan.
- Another function of the housing cover is to protect the printed circuit board from being touched.
- the printed circuit board can be easily mounted on one or both axial parts and then covered by the housing cover and enclosed in the accommodation space.
- the printed circuit board can be fixed by the housing cover on one or both axial parts.
- first axial part and the second axial part are fastened to one another, in particular screwed, by the at least one housing cover.
- the housing cover is therefore the intermediary component for producing the connection and fastening between the first and second axial part.
- the first axial part defines a flow intake section and the second axial part defines a flow exhaust section of the fan.
- the two axial parts are therefore the main elements of the fan housing.
- the fan is characterized in that the first and/or second axial part has a pocket for accommodating a connection plug of the fan connected to the printed circuit board or a connection cable of the connection plug and the at least one housing cover has a rib protruding into the receiving space. It is provided that the rib fixes the connection cable and consequently the connection plug in the pocket with strain relief. This ensures that tensile forces acting on the connection plug for the electrical connection of the fan do not act directly on the electronic components, but are absorbed by the housing cover and the axial part with the pocket. For this purpose, in particular the connection cable engaging the connection plug is placed in the pocket and held pressed in the pocket by the rib.
- the fan is also provided with the connection cable of the connection plug being fixed in the pocket by the printed circuit board and the rib.
- the printed circuit board exerts an additional holding force on the connection cable and the fixation and strain relief are therefore improved.
- the fan is characterized in that that the at least one housing cover has a retaining web which protrudes into the receiving space and is designed to fix a winding plug of the motor to the printed circuit board in relation to its position in the receiving space.
- the winding plug of the motor is fixed to the printed circuit board. Since oscillations and vibrations occur when the fan is in operation, it is advantageous to provide an additional fixation.
- This is integrated into the housing cover, in which the holding web is positioned and dimensioned in such a way that, when the housing cover is installed as intended, it engages the winding plug and fixes this in its position.
- the holding web and the winding plug can additionally have geometries which interact in a holding manner.
- the fan has a rectangular or square basic shape in an axial plan view.
- the at least one housing cover then extends along a corner of the basic shape in the axial direction over the first axial part and the second axial part.
- the housing cover is arranged on an outer lateral surface of the axial parts and determines the outer geometry of the fan in the respective corner.
- the fan is characterized in that at least one elastically resilient leg is provided on the housing cover, which is designed as a partial opening in a housing cover wall, protrudes into the receiving space and acts prestressed on the printed circuit board.
- the housing cover thus provides the additional function of spring-loaded locking of the printed circuit board. This is particularly favorable when the fan is operating with vibrations and oscillations.
- the fan housing has an intermediate piece axially between the first axial part and the second axial part, which separates part of the flow channel and the outer surface of the Fan housing forms.
- the housing cover then advantageously spans both the axial parts and the intermediate piece.
- Such intermediate pieces are used, for example, when using a plurality of fan wheels arranged axially in a row.
- a motor and a fan wheel are arranged on the intermediate piece on both axial sides.
- two housing covers are arranged on the fan housing, each of which forms its own receiving space with the fan housing and a printed circuit board for a motor is arranged in each of the receiving spaces. The features described above for the housing cover are fully applicable to both housing covers.
- FIG 1 an exemplary embodiment of a fan 1 as an axial fan with two counter-rotating fan wheels 5 is shown in a perspective view.
- the fan 1 comprises two motors, each of which drives a fan wheel 5 arranged in the flow channel, and a multi-part fan housing 2, which forms the flow channel.
- the fan housing 2 is formed by a first axial part 3, a second axial part 4 and an intermediate part 15, which is arranged between the two axial parts 3, 4 as viewed along the axis of rotation RA.
- figure 4 shows the structure in a sectional view for better understanding.
- Two sockets 27 are formed on the intermediate piece to accommodate one motor and one impeller 5 each, which are arranged in the flow channel of the fan housing 2 .
- the disclosure expressly also includes solutions that do not use an intermediate piece, but rather arrange the first and second axial parts 3, 4 directly next to one another.
- the first axial part 3 forms the flow intake section, the second axial part 4 the flow exhaust section of the fan 1.
- the fan housing 2 has an essentially square basic shape.
- housing covers 6 are arranged on the outer lateral surface of the fan housing 2, which form the corner.
- the housing covers 6 connect and fasten the first axial part 3 to the second axial part 4 by means of screws.
- the housing covers 6 are shaped in such a way that they supplement the basic shape and each form a receiving space 7 with the outer lateral surface of the fan housing 2, in which an exemplary in figure 3 circuit board 20 shown are arranged with motor electronic components for the motor.
- a separate printed circuit board 20 is used for each motor. In the case of solutions with only one motor, therefore, only one housing cover 6 can be used and a printed circuit board 20 can be positioned in the receiving space 7 formed by the one housing cover 6 .
- FIG 2 in combination with figure 1 the multifunctionality of the housing covers 6 is shown.
- a rib 12 is formed which protrudes into the receiving space 7 in the assembled state and on which the connecting cable 11 is brought into contact in the pocket 8 and is therefore fixed in such a way that strain relief of the connecting plug 10 is ensured.
- the connection cable 11 of the connection plug 10 is also fixed in the pocket 8 by the printed circuit board 20 and the rib 12 .
- Circuit board 20 shown is connected to the windings of the motor via a winding connector (not shown).
- a socket 23 for the winding connector is provided on the printed circuit board 20 .
- the printed circuit board 20 is arranged in the receiving space 7 formed by the housing cover 6 in such a way that the figure 2 shown, in the mounted state of the housing cover 6 in the receiving space 7 protruding retaining web 9 acts on the winding connector fixing and fixes its mounting position in the socket 23.
- the holding web 9 presses the winding connector against the printed circuit board 20.
- the printed circuit boards 20 are additionally fastened in the respective receiving space 7 by means of elastically resilient legs 13 formed on the housing covers 6.
- the legs 13 are designed as a partial opening in the housing cover wall 14 and press the printed circuit boards 20 into their respective assembly position with a certain material-related prestress.
- the housing cover 6 can also be designed without legs 13 .

Description
Die Erfindung betrifft einen Lüfter mit mindestens einem Motor sowie mindestens einem um eine Rotationsachse rotierbaren Lüfterrad und einem mehrteiligen Lüftergehäuse mit einer multifunktionalen Gehäuseabdeckung.The invention relates to a fan with at least one motor and at least one fan wheel that can be rotated about an axis of rotation and a multi-part fan housing with a multifunctional housing cover.
Aus dem Stand der Technik ist eine Vielzahl von Lüfter mit verschiedenen Gehäusearten bekannt. Derartige Gehäuse sind jedoch vor allem dahingehend konstruiert, die Lüfterräder auszunehmen und den Strömungskanal zu bilden, ohne dass weitere Funktionen integriert sind.A large number of fans with different types of housing are known from the prior art. However, such housings are primarily designed to remove the fan wheels and form the flow channel, without further functions being integrated.
Der Erfindung liegt deshalb die Aufgabe zugrunde, einen Lüfter mit einem Lüftergehäuse bereitzustellen, das mehrere Funktionen aufweist und technisch mit antriebsbedingt nötigen Komponenten zusammenwirkt.The invention is therefore based on the object of providing a fan with a fan housing that has a number of functions and technically interacts with components that are necessary for the drive.
Diese Aufgabe wird durch die Merkmalskombination gemäß Patentanspruch 1 gelöst.This object is achieved by the combination of features according to
Erfindungsgemäß wird ein Lüfter mit mindestens einem Motor sowie mindestens einem um eine Rotationsachse rotierbaren Lüfterrad und einem mehrteiligen Lüftergehäuse vorgeschlagen. Das Lüftergehäuse bildet einen Strömungskanal, in dem das mindestens eine Lüfterrad angeordnet ist. Zudem weist das Lüftergehäuse zumindest ein erstes Axialteil und ein zweites Axialteil auf, die in axialer Richtung entlang der Rotationsachse gesehen zueinander angeordnet sind. Der Lüfter umfasst ferner mindestens eine Gehäuseabdeckung, die an einer Außenmantelfläche des Lüftergehäuses angeordnet ist und das erste Axialteil und das zweite Axialteil miteinander verbindet. Die mindestens eine Gehäuseabdeckung bildet zudem mit der Außenmantelfläche des Lüftergehäuses einen Aufnahmeraum, in dem eine Leiterplatte mit einer Motorelektronik für den Motor angeordnet ist.According to the invention, a fan is proposed with at least one motor and at least one fan wheel that can be rotated about an axis of rotation and a multi-part fan housing. The fan housing forms a flow channel in which the at least one fan wheel is arranged. In addition, the fan housing has at least a first axial part and a second axial part, which are arranged relative to one another as viewed in the axial direction along the axis of rotation. The fan also includes at least one housing cover, which is arranged on an outer lateral surface of the fan housing and connects the first axial part and the second axial part to one another. The at least one housing cover also forms a receiving space with the outer lateral surface of the fan housing, in which a printed circuit board with motor electronics for the motor is arranged.
Die multifunktionale Gehäuseabdeckung wirkt mit den Axialteilen des Lüftergehäuses zusammen, in dem sie die beiden Axialteile verbindet und mithin die Gesamtkonstruktion stabilisiert. Gleichzeitig ermöglicht der durch die Gehäuseabdeckung gebildete Aufnahmeraum die Anordnung der Leiterplatte mit der Motorelektronik außerhalb der Strömung des Lüfters. Zudem wird als weitere Funktion der Gehäuseabdeckung die Leiterplatte vor Berührung geschützt. Die Leiterplatte kann an einem oder beiden Axialteilen leicht montiert und anschließend von der Gehäuseabdeckung abgedeckt und in den Aufnahmeraum eingeschlossen werden. Zudem ist in einer Ausführung eine Fixierung der Leiterplatte durch die Gehäuseabdeckung an einem oder beiden Axialteilen realisierbar.The multifunctional housing cover interacts with the axial parts of the fan housing by connecting the two axial parts and thus stabilizing the overall construction. At the same time, the accommodation space formed by the housing cover enables the printed circuit board with the motor electronics to be arranged outside of the flow of the fan. Another function of the housing cover is to protect the printed circuit board from being touched. The printed circuit board can be easily mounted on one or both axial parts and then covered by the housing cover and enclosed in the accommodation space. In addition, in one embodiment, the printed circuit board can be fixed by the housing cover on one or both axial parts.
Bei dem Lüfter ist ferner in einer Ausführungsvariante vorgesehen, dass das erste Axialteil und das zweite Axialteil durch die mindestens eine Gehäuseabdeckung aneinander befestigt, insbesondere verschraubt sind. Die Gehäuseabdeckung ist mithin das vermittelnde Bauteil zur Herstellung der Verbindung und Befestigung zwischen dem ersten und zweiten Axialteil.In one embodiment variant of the fan, it is also provided that the first axial part and the second axial part are fastened to one another, in particular screwed, by the at least one housing cover. The housing cover is therefore the intermediary component for producing the connection and fastening between the first and second axial part.
Bei dem Lüfter bestimmt vorzugsweise das erste Axialteil einen Strömungsansaugabschnitt und das zweite Axialteil einen Strömungsausblasabschnitt des Lüfters. Die beiden Axialteile sind mithin die Hauptelemente des Lüftergehäuses.In the fan, preferably, the first axial part defines a flow intake section and the second axial part defines a flow exhaust section of the fan. The two axial parts are therefore the main elements of the fan housing.
Der Lüfter ist in einer vorteilhaften Weiterbildung dadurch gekennzeichnet, dass das erste und/oder zweite Axialteil eine Tasche zur Aufnahme eines mit der Leiterplatte verbundenen Anschlusssteckers des Lüfters bzw. eines Anschlusskabels des Anschlusssteckers und die mindestens eine Gehäuseabdeckung eine in den Aufnahmeraum hineinragende Rippe aufweisen. Dabei ist vorgesehen, dass die Rippe das Anschlusskabel und mithin den Anschlussstecker zugentlastend in der Tasche festlegt. Somit ist sichergestellt, dass auf den Anschlussstecker zum elektrischen Anschluss des Lüfters wirkende Zugkräfte nicht unmittelbar auf die elektronischen Bauteile einwirken, sondern von der Gehäuseabdeckung und dem Axialteil mit der Tasche aufgenommen werden. Hierzu wird insbesondere das an dem Anschlussstecker angreifende Anschlusskabel in die Tasche eingelegt und durch die Rippe in der Tasche gepresst gehalten.In an advantageous development, the fan is characterized in that the first and/or second axial part has a pocket for accommodating a connection plug of the fan connected to the printed circuit board or a connection cable of the connection plug and the at least one housing cover has a rib protruding into the receiving space. It is provided that the rib fixes the connection cable and consequently the connection plug in the pocket with strain relief. This ensures that tensile forces acting on the connection plug for the electrical connection of the fan do not act directly on the electronic components, but are absorbed by the housing cover and the axial part with the pocket. For this purpose, in particular the connection cable engaging the connection plug is placed in the pocket and held pressed in the pocket by the rib.
Als Weiterbildung ist beidem Lüfter zudem vorgesehen, dass das Anschlusskabel des Anschlusssteckers durch die Leiterplatte und die Rippe in der Tasche fixiert ist. Eine derartige Lösung ist noch effektiver, da die Leiterplatte eine zusätzlich Haltekraft auf das Anschlusskabel ausübt und mithin die Fixierung und Zugentlastung verbessert sind.As a further development, the fan is also provided with the connection cable of the connection plug being fixed in the pocket by the printed circuit board and the rib. Such a solution is even more effective, since the printed circuit board exerts an additional holding force on the connection cable and the fixation and strain relief are therefore improved.
Als weitere vorteilhafte Ausgestaltung ist der Lüfter dadurch gekennzeichnet, dass die mindestens eine Gehäuseabdeckung eine in den Aufnahmeraum hineinragenden Haltesteg aufweist, der ausgebildet ist, einen Wicklungsstecker des Motors bezüglich seiner Position im Aufnahmeraum fixiert an der Leiterplatte festzulegen. Der Wicklungsstecker des Motors wird an der Leiterplatte fixiert. Da es im Betrieb des Lüfters zu Schwingungen und Vibrationen kommt, ist es günstig, eine zusätzliche Fixierung bereitzustellen. Diese wird in die Gehäuseabdeckung integriert, in dem der Haltesteg derart positioniert und dimensioniert ist, dass er bei einer bestimmungsgemäß montierten Gehäuseabdeckung an den Wicklungsstecker angreift und diesen in seiner Position festlegt. Hierzu können der Haltesteg und der Wicklungsstecker zusätzlich haltend zusammenwirkende Geometrien aufweisen.As a further advantageous embodiment, the fan is characterized in that that the at least one housing cover has a retaining web which protrudes into the receiving space and is designed to fix a winding plug of the motor to the printed circuit board in relation to its position in the receiving space. The winding plug of the motor is fixed to the printed circuit board. Since oscillations and vibrations occur when the fan is in operation, it is advantageous to provide an additional fixation. This is integrated into the housing cover, in which the holding web is positioned and dimensioned in such a way that, when the housing cover is installed as intended, it engages the winding plug and fixes this in its position. For this purpose, the holding web and the winding plug can additionally have geometries which interact in a holding manner.
Der Lüfter weist in einer Ausführungsvariante in einer axialen Draufsicht eine rechtwinklige oder quadratische Grundform auf. Die mindestens eine Gehäuseabdeckung erstreckt sich dann entlang einer Ecke der Grundform in axialer Richtung über das erste Axialteil und das zweite Axialteil. Insbesondere wird die Gehäuseabdeckung an einer äußeren Mantelfläche der Axialteile angeordnet und bestimmt die Außengeometrie des Lüfters in der jeweiligen Ecke.In an embodiment variant, the fan has a rectangular or square basic shape in an axial plan view. The at least one housing cover then extends along a corner of the basic shape in the axial direction over the first axial part and the second axial part. In particular, the housing cover is arranged on an outer lateral surface of the axial parts and determines the outer geometry of the fan in the respective corner.
Als weitere vorteilhafte Ausgestaltung ist der Lüfter dadurch gekennzeichnet, dass an der Gehäuseabdeckung mindestens ein elastisch federnder Schenkel vorgesehen ist, der als Teildurchbruch einer Gehäuseabdeckungswandung ausgebildet ist, in den Aufnahmeraum hineinragt und vorgespannt an die Leiterplatte angreift. Die Gehäuseabdeckung liefert dadurch die weitere Funktion der federnden Arretierung der Leiterplatte. Dies ist im Betrieb des Lüfters mit Vibrationen und Schwingungen besonders günstig.As a further advantageous embodiment, the fan is characterized in that at least one elastically resilient leg is provided on the housing cover, which is designed as a partial opening in a housing cover wall, protrudes into the receiving space and acts prestressed on the printed circuit board. The housing cover thus provides the additional function of spring-loaded locking of the printed circuit board. This is particularly favorable when the fan is operating with vibrations and oscillations.
Bei einer weiteren Weiterbildung des Lüfters weist das Lüftergehäuse axial zwischen dem ersten Axialteil und dem zweiten Axialteil ein Zwischenstück auf, das einen Teil des Strömungskanals und der Außenmantelfläche des Lüftergehäuses bildet. Die Gehäuseabdeckung überspannt dann vorteilhafterweise sowohl die Axialteile als auch das Zwischenstück. Derartige Zwischenstücke werden beispielsweise bei der Verwendung mehreren axial in riehe angeordneten Lüfterrädern eingesetzt.In a further development of the fan, the fan housing has an intermediate piece axially between the first axial part and the second axial part, which separates part of the flow channel and the outer surface of the Fan housing forms. The housing cover then advantageously spans both the axial parts and the intermediate piece. Such intermediate pieces are used, for example, when using a plurality of fan wheels arranged axially in a row.
Deshalb sind in einem Ausführungsbeispiel der vorliegenden Offenbarung an dem Zwischenstück auf beiden axialen Seiten jeweils ein Motor und ein Lüfterrad angeordnet. An dem Lüftergehäuse sind zudem zwei Gehäuseabdeckungen angeordnet, die jeweils mit dem Lüftergehäuse einen eigenen Aufnahmeraum bilden und in jedem der Aufnahmeräume eine Leiterplatte für einen Motor angeordnet ist. Die vorstehend für die Gehäuseabdeckung beschriebenen Merkmale sind vollumfänglich auf beide Gehäuseabdeckungen anwendbar.Therefore, in one exemplary embodiment of the present disclosure, a motor and a fan wheel are arranged on the intermediate piece on both axial sides. In addition, two housing covers are arranged on the fan housing, each of which forms its own receiving space with the fan housing and a printed circuit board for a motor is arranged in each of the receiving spaces. The features described above for the housing cover are fully applicable to both housing covers.
