Description

Die Erfindung bezieht sich auf eine Wärmeaustauschvorrichtung mit parallel zueinander angeordneten Rohren und quer zu diesen verlaufenden Rippen, die gewellt ausgebildet sind und mit den Wellenbergen aneinanderliegen. The invention relates to a heat exchange device with parallel to each other arranged tubes and transversely to these ribs that are corrugated are and lie against each other with the wave crests.

Bei den bekannten Wärmeaustauschvorrichtungen dieser Art liegen die Wellenberge einer Rippe auf deren ganzer Länge unmittelbar an den benachbarten Rippen an, so daß gegeneinander geschlossene . Kanäle gebildet werden, die keinerlei Verbindung zu den benachbarten Kanälen besitzen. Ist dabei die Länge einer Welle kleiner als der Rohrdurchmesser, so werden zwischen den Rohren die Kanäle in sich vollständig abgeschlossen. Da diese Kanäle allseitig geschlossen sind, können sie an der Luftströmung überhaupt nicht teilnehmen, so daß dadurch der Wärmeso austausch beeinträchtigt ist.In the known heat exchange devices of this type, the wave crests are located a rib along its entire length directly to the adjacent ribs, so that closed against each other. Channels are formed that have no connection whatsoever to the neighboring ones Own channels. If the length of a shaft is smaller than the pipe diameter, in this way, the channels between the pipes are completely closed off. There If these channels are closed on all sides, they cannot take part in the air flow at all participate, so that the heat exchange is affected.

Nach der Erfindung ist dieser Nachteil dadurch behoben, daß die Wellenhöhe an den Berührungsstellen der Rohre mit den Rippen kleiner sind als die Höhen der an den Stellen zwischen den Rohren vorgesehenen Wellen, deren Länge kleiner ist als der Rohrdurchmesser. Auf diese Weise ist erreicht, daß die zwischen den Rohren gelegenen Räume auf jeden Fall seitlich an die benachbarten, durch die Wellen der Rippen gebildeten Kanäle angeschlossen sind. Damit ist 'die Gewähr dafür gegeben, daß auch zwischen den Rohren die gleiche Strömung stattfinden kann wie an den übrigen Stellen der Wärmeaustauschvorrichtung. Dadurch ist der Wirkungsgrad gegenüber den bekannten Äustauschern wesentlich erhöht.According to the invention, this disadvantage is eliminated in that the wave height to the Contact points of the tubes with the ribs are smaller than the heights of the points Shafts provided between the pipes, the length of which is smaller than the pipe diameter. In this way it is achieved that the spaces located between the pipes in any case laterally to the neighboring ones channels formed by the corrugations of the ribs are connected. This is the guarantee for it given that the same flow can take place between the pipes as on the other places of the heat exchange device. This is the efficiency significantly increased compared to the known exchangers.

Auf der Zeichnung ist schematisch eine Ausführungsform der Erfindung dargestellt.An embodiment of the invention is shown schematically in the drawing.

Die Wärmeaustauschvorrichtung besteht aus Rohren a, die durch gewellte Rippen b hindurchgeführt sind. An den Stellen, an denen die Rohre α durch die Rippen b hindurchtreten, sind diese mit kleinen Wellen c versehen. An den übrigen Stellen der Rippen sind die Wellen d wesentlich größer, ihre Länge ist aber immer noch kleiner als der Rohrdurchmesser. Die Wellen d berühren sich gegenseitig, so daß zwischen ihnen gegeneinander abgeschlossene Kanäle gebildet werden. Dagegen liegen die Wellen c der einzelnen Rippen b in einem Abstand voneinander, so daß eine Strömung des Wärmeaustauschmittels um die Rohre α herum stattfinden kann.The heat exchange device consists of tubes a which are passed through corrugated fins b . At the points where the tubes α pass through the ribs b , these are provided with small waves c . At the other points of the ribs, the waves d are much larger, but their length is still smaller than the pipe diameter. The waves d touch each other, so that mutually closed channels are formed between them. In contrast, the waves c of the individual ribs b are at a distance from one another, so that a flow of the heat exchange medium around the tubes α can take place.
