Abstract
Description
Die Erfindung betrifft eine Einrichtung umfassend eine funktionelle Komponente in einem ein Prozessfluid führenden Kanal, wobei die Komponente von dem Prozessfluid in turbulenter Strömung durchströmbar ist und der Komponente ein in dem Kanal angeordneter Strömungsgleichrichter zugeordnet ist.The The invention relates to a device comprising a functional Component in a process fluid channel, the component of the process fluid can be flowed through in turbulent flow and the component has a flow straightener disposed in the channel assigned.
Eine
solche Einrichtung geht hervor aus der
Unter der Adresse http://www.tubus-bauer.com/ sind am 27.07.2005 im Internet Hinweise zu Wabenkörpern öffentlich verfügbar gewesen, wobei die Wabenkörper unter anderem zur Erzeugung eines gleichmäßigen und von Turbulenzen freien Luftstromes geeignet sind. Die Wabenköper bestehen aus Plastikwerkstoffen, insbesondere Polypropylen oder Polycarbonat.Under the address http://www.tubus-bauer.com/ are on the 27.07.2005 in the Internet Information about honeycomb bodies in public available been, with the honeycomb body among other things, to produce a uniform and turbulence-free Air flow are suitable. The honeycomb bodies are made of plastic materials, in particular polypropylene or polycarbonate.
In einem Wäschetrockner des Kondensationstyps wird erwärmte Prozessluft an zu trocknender Wäsche vorbeigeführt und anschließend in einem Wärmetauscher abgekühlt, so dass mitgeführte Feuchtigkeit kondensiert und abgeschieden werden kann. Der entsprechende Energieaustausch soll in möglichst kleinem Volumen und möglichst intensiv erfolgen, weshalb auf die Ausbildung einer turbulenten Strömung großer Wert gelegt wird. Die turbulente Strömung ist dabei wünschenswert sowohl für die zum Trocknen der Wäsche direkt genutzte und in einem Kreislauf geführte Prozessluft als auch für die Kühlluft, welche in dem genannten Wärmetauscher zur Abkühlung der Prozessluft eingesetzt wird. Eine turbulente Strömung ist stets verbunden mit Strömungsgeräuschen, welche deutlich lauter als Strömungsgeräusche in laminaren Strömungen sind. Dementsprechend ist es wünschenswert, in einem Prozessluft führenden Hausgerät, wie einem Wäschetrockner, eine turbulente Strömung jedenfalls dann zu vermeiden, wenn sie für die Funktion des Hausgerätes nicht unbedingt notwendig ist, wie soeben für einen Wärmetauscher in einem Wäschetrockner beschrieben.In a tumble dryer of the condensation type is heated Process air on laundry to be dried past and subsequently in a heat exchanger cooled, so that carried moisture can be condensed and separated. The corresponding energy exchange should be in as possible small volume and as possible intensive, which is why the formation of a turbulent flow greater Value is placed. The turbulent flow is desirable as well as the drying of the laundry directly used and circulated process air as well as for the cooling air, which in the said heat exchanger for Cooling the process air is used. A turbulent flow is always connected with flow noise, which is significantly louder than flow noise in laminar flows are. Accordingly, it is desirable leading in a process air Household appliance, like a tumble dryer, a turbulent flow at least then, if they are not for the function of the household appliance absolutely necessary, as just for a heat exchanger in a tumble dryer described.
Dementsprechend liegt der nachfolgend darzulegenden Erfindung die Aufgabe zugrunde, eine Einrichtung der eingangs genannten Gattung anzugeben, bei welcher die Erzeugung eines unerwünschten Strömungsgeräusches in dem ein Prozessfluid führenden Kanal soweit wie möglich vermieden ist.Accordingly the invention to be presented below is based on the object, to provide a device of the type mentioned, in which the generation of an undesirable Flow noise in leading a process fluid Channel as far as possible is avoided.
Zur Lösung dieser Aufgabe angegeben wird eine Einrichtung umfassend eine funktionelle Komponente in einem ein Prozessfluid führenden Kanal, wobei die Komponente von dem Prozessfluid in turbulenter Strömung durchströmbar ist und der Komponente ein in dem Kanal angeordneter Strömungsgleichrichter zugeordnet ist, welcher entsprechend der Erfindung an einer Abströmseite der Komponente angeordnet ist.to solution This object is achieved by a device comprising a functional Component in a process fluid channel, wherein the component can be flowed through by the process fluid in turbulent flow and the component has a flow straightener disposed in the channel is assigned, which according to the invention on a downstream side of the Component is arranged.
Die Erfindung geht aus von der Erkenntnis, dass es zur Vermeidung eines unerwünschten Strömungsgeräusches nicht ausreicht, Strömungsverhältnisse innerhalb funktioneller Komponenten zu betrachten, die in dem das Prozessfluid führenden Kanals angeordnet sind, sondern dass es erforderlich ist, den Kanal außerhalb solcher Komponenten zu betrachten und geeignete Mittel zum Zweck vorzusehen.The Invention is based on the knowledge that it helps to avoid undesirable No flow noise sufficient, flow conditions within functional components in which the Process fluid leading Channels are arranged, but that it is necessary, the channel outside consider such components and appropriate means to an end provided.
Vorzugsweise ist der Strömungsgleichrichter ein Wabenkörper, und weiterhin vorzugsweise ist der Strömungsgleichrichter im Wesentlichen unmittelbar an die funktionelle Komponente, welcher er zugeordnet ist, angesetzt.Preferably is the flow straightener on Honeycombs, and further preferably, the flow straightener is substantially directly to the functional component to which it is assigned is scheduled.
Der Kanal gehört vorzugsweise zu einem Hausgerät, insbesondere zu einem zur Behandlung von Wäsche bestimmten Hausgerät, bei welchem das Prozessfluid Luft ist. Besonders bevorzugt ist die Einrichtung in einem Wäschetrockner realisiert, wobei die Komponente ausgewählt ist aus einer Gruppe umfassend einen Wärmetauscher und eine Siebvorrichtung, beispielsweise ein Flusensieb. Die einen Wärmetauscher umfassende Einrichtung ist mit besonderem Vorzug eingesetzt in einem Kanal, in welchem das Prozessfluid in einem Kreislauf geführt wird.Of the Channel heard preferably to a household appliance, in particular to a household appliance intended for the treatment of laundry, in which the Process fluid is air. Particularly preferred is the device in a tumble dryer realized, wherein the component is selected from a group comprising a heat exchanger and a screening device, such as a lint filter. The one heat exchanger Comprehensive facility is used with particular preference in one Channel in which the process fluid is circulated.
Außer bei einem Wäschetrockner des Kondensationstyps, wie oben beschrieben, ist die Erfindung anwendbar in einem Wäschetrockner des Ablufttyps, bei dem die Prozessluft nicht in einem Kreislauf geführt wird; die Prozessluft wird vielmehr einer Umgebung des Trockners entnommen, anschließend aufgeheizt und durch die zu trocknende Wäsche geführt und dann endlich in die Umgebung entlassen. Dabei findet die Erfindung vorteilhafte Anwendung zur Vergleichmäßigung der Strömung der Prozessluft hinter einem Flusensieb, welche zur Entfernung mitgeführte Flusen aus der Prozessluft benutzt wird.Except for a clothes dryer of the condensation type as described above, the invention is applicable to a clothes dryer of the exhaust type, in which the process air is not circulated; the process air is rather taken from an environment of the dryer, then heated and passed through the laundry to be dried and then finally released into the environment. The invention finds advantageous application for equalization of the flow of process air behind a lint filter, which for removal with Guided lint from the process air is used.
