Description
Die Erfindung betrifft eine Trägerplatte für einen mit Elektronikkomponenten bestückten Schaltungsträger eines Haushaltsgeräts, welche Aufnahmen für den Schaltungsträger aufweist. Darüber hinaus betrifft die Erfindung auch eine Anordnung mit einer Trägerplatte und einem Elektronikkomponententräger, sowie ein Induktionskochfeld mit einer entsprechenden Anordnung.The invention relates to a carrier plate for a circuit board equipped with electronic components of a household appliance, which has receptacles for the circuit carrier. Moreover, the invention also relates to an arrangement with a carrier plate and an electronic component carrier, as well as an induction hob with a corresponding arrangement.
Bei Haushaltsgeräten, insbesondere Induktionskochfeldern, sind eine Vielzahl von Elektronikkomponenten vorhanden, die im Betrieb gekühlt werden müssen. Dies betrifft insbesondere die Leistungselektronikbauelemente, die zur Energieversorgung der Induktoren des Induktionskochfelds vorgesehen sind. Entsprechendes ist aus der
Bei herkömmlichen Induktionskochfeldern wird eine Kühlung dadurch erreicht, dass mittels einem Gebläse ein Kühlluftstrom erzeugt wird, der in Richtung des Kühlkörpers, in dem die Elektronikkomponenten montiert sind, gerichtet wird. Sowohl die Strömungszufuhr zum Kühlkörper als auch der Kühlungseffekt sind dadurch funktionell eingeschränkt und die Kühlungswirkung beschränkt.In conventional induction hobs cooling is achieved by means of a fan, a cooling air flow is generated, which is directed towards the heat sink in which the electronic components are mounted. Both the flow of heat to the heat sink and the cooling effect are thereby functionally limited and limited the cooling effect.
Es ist Aufgabe der vorliegenden Erfindung, eine Trägerplatte für einen mit Elektronikkomponenten bestückten Schaltungsträger eines Haushaltsgeräts, eine Anordnung mit einer derartigen Trägerplatte, sowie ein Induktionskochfeld bereitzustellen, mit welcher bzw. mit welchem die Kühlluftzuführung zum Kühlen der Elektronikkomponenten verbessert ist.It is an object of the present invention to provide a support plate for a circuit board equipped with electronic components of a household appliance, an arrangement with such a support plate, and an induction hob, with which or with which the cooling air supply for cooling the electronic components is improved.
Diese Aufgabe wird durch eine Trägerplatte, welche die Merkmale nach Anspruch 1 aufweist, eine Anordnung, welche die Merkmale nach Anspruch 12 aufweist, und ein Induktionskochfeld, welches die Merkmale nach Anspruch 15 aufweist, gelöst.This object is achieved by a support plate having the features of claim 1, an assembly having the features of
Eine erfindungsgemäße Trägerplatte ist zum Tragen bzw. Aufnehmen eines mit Elektronikkomponenten bestückten Schaltungsträger eines Haushaltsgeräts konzipiert. Die Trägerplatte ist zur Aufnahme für den Schaltungsträger ausgebildet, und weist dazu entsprechende gegenständliche Aufnahmen auf. Auf der Trägerplatte ist ein Wände umfassender länglicher Strömungskanal ausgebildet, welcher zur Leitung von Kühlluft von Elektronikkomponenten des Schaltungsträgers ausgebildet ist. Die den Strömungskanal begrenzenden Wände sind zumindest teilweise durch die Trägerplatte selbst gebildet. Die Wände sind so angeordnet, dass sich die Kanalform des Strömungskanals ausbildet und sich somit ein länglicher und zumindest teilweise geschlossener Hohlkörper ausbildet. Durch eine derartige Ausgestaltung kann quasi integral ein spezifisches Bauteil, nämlich der Strömungskanal, auf der Trägerplatte gebildet werden, wodurch die Strömungsführung der Kühlluft wesentlich gezielter und effizienter erfolgen kann und dadurch das Kühlen der Elektronikkomponenten wesentlichen effizienter erfolgen kann. Darüber hinaus wird durch diesen integralen Strömungskanal auch vermieden, dass Kühlluft quasi unkontrolliert ausgeblasen und damit auch in unerwünschte Zonen geblasen wird.A carrier plate according to the invention is designed for carrying or picking up a circuit carrier of a domestic appliance equipped with electronic components. The carrier plate is designed for receiving the circuit carrier, and has corresponding representational recordings for this purpose. On the support plate a wall comprehensive elongated flow channel is formed, which is designed to conduct cooling air from electronic components of the circuit substrate. The walls bounding the flow channel are at least partially formed by the carrier plate itself. The walls are arranged so that the channel shape of the flow channel is formed and thus forms an elongated and at least partially closed hollow body. By means of such a configuration, a specific component, namely the flow channel, can be virtually formed integrally on the carrier plate, as a result of which the flow guidance of the cooling air can be substantially more targeted and efficient, and the cooling of the electronic components can thus take place substantially more efficiently. In addition, it is also avoided by this integral flow channel that cooling air is blown out virtually uncontrolled and thus blown into unwanted zones.
Indem der Strömungskanal darüber hinaus auch noch teilweise durch die Trägerplatte selbst gebildet ist, kann eine sehr Bauteilminimierte wie auch mechanisch stabile und robuste Ausgestaltung erzielt werden.In addition, because the flow channel is also partly formed by the carrier plate itself, a very component-minimized as well as mechanically stable and robust configuration can be achieved.
Vorzugsweise ist vorgesehen, dass der Strömungskanal an einer Längsseite offen ausgebildet ist und ein Aufnahmeschacht zum seitlichen Einführen eines Elektronikkomponententrägers ausgebildet ist. Dies ist eine besonders hervorzuhebende Ausführung, da somit gewährleistet ist, dass der Elektronikkomponententräger zumindest sich auch bereichsweise in den Aufnahmeschacht hinein erstrecken kann und somit die Kühlwirkung beim Vorbeiströmen der Kühlluft besonders hoch ist. Darüber hinaus wird durch ein derartiges quasi Hineinerstrecken des Elektronikkomponententrägers in den Strömungskanal auch wiederum eine sehr bauraumminimierte Ausgestaltung bereitgestellt. Nicht zuletzt kann durch eine derartige Anordnung auch eine sehr mechanisch stabile Positionierung des Elektronikkomponententrägers erreicht werden, da der Elektronikkomponententräger zumindest anteilig durch den durch die Trägerplatte gebildeten Teil des Strömungskanals gehalten und positioniert werden kann. Vorzugsweise ist vorgesehen, dass der Aufnahmeschacht in Längsrichtung des Strömungskanals betrachtet an einer offenen Seitenwand und/oder an einer offenen Deckenwand durch einen Strömungskanaleinlassflansch und einen Strömungskanalauslassflansch begrenzt ist. In Längsrichtung des Strömungskanals betrachtet ist somit dieser Aufnahmeschacht vorne und hinten klar begrenzt und somit kann auch das Einführen des Elektronikkomponententrägers sehr gezielt und quasi auch geführt erfolgen. Dies ist insbesondere dann besonders vorteilhaft, wenn der Elektronikkomponententräger Ausmaße aufweist, die passgenau ein Einführen in den Aufnahmeschacht ermöglichen.It is preferably provided that the flow channel is designed to be open on one longitudinal side and a receiving shaft for lateral insertion of an electronic component carrier is formed. This is a particularly noteworthy embodiment, since it is thus ensured that the electronic component carrier can at least partially also extend into the receiving shaft and thus the cooling effect when passing the cooling air is particularly high. In addition, by such a quasi Hineinerstrecken the electronic component carrier in the flow channel in turn a very space-minimized design provided. Not least can be achieved by such an arrangement, a very mechanically stable positioning of the electronic component carrier, since the electronic component carrier can be at least partially held and positioned by the part formed by the support plate of the flow channel. Preferably, it is provided that the receiving shaft, viewed in the longitudinal direction of the flow channel, is delimited on an open side wall and / or on an open top wall by a flow channel inlet flange and a flow channel outlet flange. Considered in the longitudinal direction of the flow channel, therefore, this receiving shaft is clearly delimited front and rear, and thus the insertion of the electronic component carrier can also be carried out in a very targeted and quasi-guided manner. This is particularly advantageous in particular when the electronic component carrier has dimensions which allow an exact insertion into the receiving shaft.
Indem der Aufnahmeschacht dahingehend konzipiert ist, dass der Strömungskanal sowohl an einer Seitenwand als auch an einer Deckenwand offen ist, kann das Einführen besonders einfach und zuverlässig erfolgen, ohne dass ein Verspreizen oder Verklemmen des Elektronikkomponententrägers einhergehen würde.By designing the receiving well such that the flow channel is open both on a side wall and on a top wall, the introduction can be carried out particularly simply and reliably without being accompanied by any spreading or jamming of the electronic component carrier.
Vorzugsweise ist vorgesehen, dass eine offene Seitenwand des Strömungskanals einen in der Höhe reduzierten, insbesondere maximal ein Drittel der Höhe des Strömungskanals getragenen, Wandsteg aufweist, welcher funktionell zur Positionierung des Komponententrägers vorzugsweise vorgesehen ist. Insbesondere erstreckt sich dieser Wandsteg über die gesamte Länge des Aufnahmeschachts. Er erstreckt sich somit insbesondere auch von dem Strömungskanaleinlassflansch bis hin zum Strömungskanalauslassflansch.Preferably, it is provided that an open side wall of the flow channel has a reduced in height, in particular a maximum of one third of the height of the flow channel supported wall web, which is preferably provided functionally for positioning of the component carrier. In particular, this wall web extends over the entire length of the receiving shaft. It therefore also extends in particular from the flow channel inlet flange to the flow channel outlet flange.
Vorzugsweise ist dabei vorgesehen, dass der Elektronikkomponententräger eine kompatible Aussparung aufweist, in welche dann der Wandsteg eingreifen kann.Preferably, it is provided that the electronic component carrier has a compatible recess into which the wall web can then engage.
Es kann auch vorgesehen sein, dass der Wandsteg zumindest abschnittsweise nicht-geradlinig verlaufend ausgebildet ist. Die Anpassung an den Elektronikkomponententräger kann dabei individuell erfolgen. Vorzugsweise erstreckt sich der Wandsteg an seinen beiden gegenüberliegenden Enden mit einem kleinen bzw. kurzen Abschnitt gewinkelt in Richtung der Außenwandbereiche des Strömungskanaleinlassflansches und des Strömungskanalauslassflansches. Der Wandsteg ist somit insbesondere ein geringfügig gegenüber der Außenseite des Strömungskanaleinlassflansches und des Strömungskanalauslassflansches nach außen versetzter Wandbereich. Dies ist insbesondere vorteilhaft für die Aufnahme und Einführung des Elektronikkomponententrägers in den Aufnahmeschacht. Darüber hinaus ist dadurch gewährleistet, dass gerade bei einem nicht-geradlinig verlaufenden Wandsteg, der sich dann vorzugsweise nicht in den Strömungskanal mit seinen nicht-geradlinigen Abschnitten hineinerstreckt, keine unerwünschten Verwirbelungen des Kühlluftstroms bewirkt sind.It can also be provided that the wall web is at least partially non-rectilinear design. The adaptation to the electronic component carrier can be done individually. Preferably, the wall web extends at its two opposite ends with a small or short section angled in the direction of the outer wall portions of the Strömungskanaleinlassflansches and the Strömungskanalauslassflansches. The wall web is therefore in particular slightly outward with respect to the outside of the flow channel inlet flange and the flow channel outlet flange offset wall area. This is particularly advantageous for receiving and introducing the electronic component carrier in the receiving shaft. In addition, this ensures that especially in a non-rectilinear wall web, which then preferably does not hineinerstreckt into the flow channel with its non-linear sections, no undesirable turbulence of the cooling air flow are effected.
Vorzugsweise ist vorgesehen, dass der Strömungskanal frontseitig durch einen Strömungskanaleinlassflansch aus Wandbereichen begrenzt ist. Dieser ist insbesondere trichterförmig ausgebildet. Diese spezifische Formgebung ermöglicht eine besonders große Aufnahme des Kühlluftgebläses in einem Kühlluftstrom.It is preferably provided that the flow channel is delimited on the front side by a flow channel inlet flange of wall regions. This is in particular funnel-shaped. This specific shape allows a particularly large intake of the cooling air blower in a cooling air flow.
Vorzugsweise ist vorgesehen, dass benachbart zum Strömungskanaleinlassflansch eine Strömungsöffnung zum Einleiten der Kühlluft in den Strömungskanal in den Boden der Trägerplatte ausgebildet ist. Vorzugsweise ist bei einer Betrachtung von oben der Trägerplatte diese Strömungsöffnung nicht überlappend mit der Fläche des Strömungskanalseinlassflansches angeordnet. Vorzugsweise ist vorgesehen, dass der Strömungskanal rückseitig durch einen Strömungskanalauslassflansch aus Wandbereichen begrenzt ist, welcher mit seiner Deckenwand schräg abfallend nach unten ausgebildet ist. Dies ist besonders vorteilhaft im Hinblick auf die Kühlluftströmung zum Auslass. Gezielt kann dadurch der abzuführende aufgewärmte Kühlluftstrom abgeleitet werden.It is preferably provided that a flow opening for introducing the cooling air into the flow channel is formed in the bottom of the carrier plate adjacent to the flow channel inlet flange. Preferably, when viewed from above the carrier plate, this flow opening is not arranged overlapping the surface of the flow channel inlet flange. It is preferably provided that the flow channel is bounded on the rear side by a flow channel outlet flange of wall regions, which is formed with its ceiling wall sloping downwards. This is particularly advantageous with regard to the cooling air flow to the outlet. In this way, it is possible to divert the warmed up cooling air flow to be discharged.
Besonders vorteilhaft ist dies dann, wenn direkt unter der Deckenwand eine Strömungsöffnung zum Ausleiten der Kühlluft aus dem Strömungskanal in den Boden der Trägerplatte ausgebildet ist. Vorzugsweise wird dann diese weitere Strömungsöffnung quasi von oben durch den Strömungskanal haubenartig abgedeckt, insbesondere durch den Strömungskanalauslassflansch abgedeckt. Die sehr gezielte Ableitung durch den Boden der Trägerplatte kann dadurch erreicht werden und ein unerwünschtes Anströmen von weiteren Komponenten auf der Oberseite der Trägerplatte, auf der auch der Strömungskanal ausgebildet ist, kann vermieden werden.This is particularly advantageous if directly under the ceiling wall, a flow opening for discharging the cooling air from the flow channel is formed in the bottom of the support plate. Preferably, then, this further flow opening is quasi covered from above by the flow channel hood-like, in particular covered by the Strömungskanalauslassflansch. The very targeted discharge through the bottom of the support plate can be achieved and an undesirable influx of other components on the top of the support plate, on which the flow channel is formed, can be avoided.
Vorzugsweise ist die Trägerplatte einstückig ausgebildet. Dadurch kann eine sehr bauteilminimierte Realisierung realisiert werden. Insbesondere kann dadurch eine Ausgestaltung aus Kunststoff realisiert werden, welche dann insbesondere als Kunststoff-Spritzgussteil gefertigt werden kann.Preferably, the carrier plate is integrally formed. As a result, a very component-minimized realization can be realized. In particular, this can be a Implementation be realized from plastic, which can then be made in particular as a plastic injection molded part.
Vorzugsweise ist vorgesehen, dass der Strömungskanal bei Draufsicht auf die Trägerplatte horizontal verlaufend angeordnet ist. Zusätzlich oder stattdessen kann auch vorgesehen sein, dass der Strömungskanal bei einer Draufsicht auf die Trägerplatte in einem hinteren Drittel der Flächenausmaße der Trägerplatte angeordnet ist. Dies ist besonders vorteilhaft im Hinblick auf die Anordnung von weiteren Bauteilen, einerseits auf der Trägerplatte selbst, andererseits auf dem Schaltungsträger und auch benachbart zu der Trägerplatte selbst. Gerade im Hinblick auf die Positionierung des Gebläses in einem Haushaltsgerät kann durch diese Anordnung des Strömungskanals eine besonders vorteilhafte Anordnung bezüglich der Bauraumkompaktheit realisiert werden.It is preferably provided that the flow channel is arranged to extend horizontally when viewed from above on the carrier plate. Additionally or instead, it can also be provided that the flow channel is arranged in a rear view of the carrier plate in a rear third of the surface dimensions of the carrier plate. This is particularly advantageous with regard to the arrangement of further components, on the one hand on the support plate itself, on the other hand on the circuit carrier and also adjacent to the support plate itself. Especially with regard to the positioning of the blower in a household appliance can be a particularly by this arrangement of the flow channel advantageous arrangement can be realized with respect to the installation space compactness.
Des Weiteren betrifft die Erfindung eine Anordnung mit einer Trägerplatte gemäß der Erfindung oder einer vorteilhaften Ausgestaltung davon. Die Anordnung umfasst darüber hinaus einen Elektronikkomponententräger auf dem zumindest eine zu kühlende Elektronikkomponente angeordnet ist.Furthermore, the invention relates to an arrangement with a carrier plate according to the invention or an advantageous embodiment thereof. The arrangement further comprises an electronic component carrier on which at least one electronic component to be cooled is arranged.
Vorzugsweise ist der Elektronikkomponententräger zumindest bereichsweise als Kühlkörper ausgebildet, welcher in dem Aufnahmeschacht des Strömungskanals angeordnet ist und bereichsweise, insbesondere mit parallel zur Längsrichtung des Strömungskanals sich erstreckenden Kühlrippen, in den Strömungskanal sich hineinerstreckend positioniert ist. Insbesondere ist der Elektronikkomponententräger so in dem Aufnahmeschacht angeordnet, dass er den Strömungskanal auf seiner offenen Seitenwand und/oder seiner offenen Deckenwand verschließend angeordnet ist. Ein unerwünschter Kühlluftstromaustritt ist dabei vermeidbar. Des Weiteren kann durch diese Anordnung ein besonders hervorzuhebendes Kühlkonzept ermöglicht werden, und darüber hinaus der Elektronikkomponententräger durch den Strömungskanal mechanisch stabil gehalten und positioniert werden.Preferably, the electronic component carrier is at least partially formed as a heat sink, which is arranged in the receiving shaft of the flow channel and partially, in particular with parallel to the longitudinal direction of the flow channel extending cooling fins, is positioned hineinerstreckend in the flow channel. In particular, the electronic component carrier is arranged in the receiving shaft such that it is arranged to occlude the flow channel on its open side wall and / or its open ceiling wall. An undesirable cooling air flow outlet is avoidable. Furthermore, a particularly noteworthy cooling concept can be made possible by this arrangement, and, moreover, the electronic component carrier can be kept mechanically stable and positioned by the flow channel.
Vorzugsweise ist vorgesehen, dass der Elektronikkomponententräger in dem sich über die gesamte Länge des Aufnahmeschachts zwischen dem Strömungskanaleinlassflansch und dem Strömungskanalauslassflansch sich erstreckenden Wandsteg eingreifend angeordnet ist. Durch diesen Wandsteg wird somit auch eine Halterung und Fixierung geschaffen, sodass der Elektronikkomponententräger insbesondere auch verrutschsicher positioniert ist.It is preferably provided that the electronic component carrier is arranged engaging in the over the entire length of the receiving shaft between the Strömungskanaleinlassflansch and the Strömungskanalauslassflansch extending wall web. By this wall bar is thus also a holder and fixation created, so that the electronic component carrier is positioned in particular slip-proof.
Des Weiteren betrifft die Erfindung ein Induktionskochfeld mit einer erfindungsgemäßen Anordnung oder einer vorteilhaften Ausgestaltung davon.Furthermore, the invention relates to an induction hob with an inventive arrangement or an advantageous embodiment thereof.
