Abstract

The guide plates within the space between heat exchanger pipes are used to generate turbulence in cooling medium for improving heat transfer rate. The transfer plates used for this purpose can have any length, width and thickness and stabilisers as well as edge reinforcement can be provided. The plates are perforated so that the material of the plates is bulging outwards and openings are formed with deflector ribs. The plates are arranged across the flow path and the flow through the holes is deflected so that turbulence is generated and flow speed is reduced in order to increase the heat transfer rate.

Description

Bezeichnung : Ouerlamelle mit Leitschnitten für Warmetauscher 1.) Sinn und Zweck der Leitschnitte Wärmetauscher werden zur Vergrößerung der Kühlfläche mit Querlamellen versehen (indirekte Kühlfläche). Um den Durchfluß in den Rohren abzubremsen, werden Wirbelbleche eingezogen. Bei der vorliegenden Erfindung handelt es sich um Leitschnitte in den t'uerlamellen, die außerhalb der Pohre liegen.Designation: Ouer lamella with guide cuts for heat exchanger 1.) The purpose of the guide cuts Heat exchangers are used to enlarge the cooling surface provided with transverse fins (indirect cooling surface). To the flow in the pipes to brake, vortex plates are drawn in. The present invention is These are leading cuts in the door lamellae that lie outside the river.

Das Kühlmedium wird durch die Schnitte umgeleitet und verwirbelt, vermindert dadurch die Durchstrnmgeschwindigkeit und ein höherer Wärmeübergang wird erzielt (I.), der ca.15 % über der hisher bekannten Herstellungsart liegt. The cooling medium is diverted and swirled through the cuts, this reduces the flow velocity and increases the heat transfer achieved (I.), which is about 15% above the previously known production method.

2.) Beschreibung 2.1 Ausführung der Lamelle Die Ausfuehrung der nuerlamelle kann beliebig sein, ebenso die Länge, Breite und Starke. Dabei können noch zusätzlich StabilisatOren (Sicken etc.) vorhanden sein sowie Randverstärkungen an den Kanten der Lamelle.2.) Description 2.1 Execution of the lamella The execution of the natural lamella can be anything, as well as length, width and thickness. You can also use Stabilizers (beads, etc.) must be present as well as edge reinforcements on the edges the lamella.

2.2 Arten, Lage, Größe und Kombinationen der Leitschnitte Die Art der Ausbauchung des Schnittes kann je nach 4rt der Fertigung verschiedene Formen haben, z.B. eckig, rund oder eine Kombination aus beiden Formen sein. Außerdem kann die Ausbauchung des Schnittes nach oben oder nach unten sein.(I.) Dabei ist nicht festgelegt, ob die Qushauchungen nur in einer wichtung sind (II.t), abwechselnd nach on und unten (II.1) oder blockweise abwechselnd nach oben und unten (II.3) Die Schnitte können zwischen den Röhrchen, vor bzw. nach den Qöhrchen liegen, oder die Lage kann eine Kombination der Plöglichkeiten sein (III.), Der Winkel zwischen Schnittkante und Röhrchen kann beliebig sein, Die größe der Schnitte ist abhängig von dem vorhandenen Platz und deren Anzahl.2.2 Types, position, size and combinations of the guiding cuts Art The bulge of the cut can take different forms depending on the type of production e.g. be angular, round or a combination of both shapes. Also can the bulge of the incision upwards or downwards. (I.) Here is not Determines whether the qushas are only in one weighting (II.t), alternately up and down (II.1) or alternately up and down in blocks (II.3) The cuts can be between the tubes, before or after the tubes, or the location can be a combination of the possibilities (III.), the angle between The cut edge and tube can be any, the size of the cut depends of the available space and their number.

2.3 Ausführung des Rohrdurchbiuchee in der Lamelle und der Rohre Die !größe und For:i des Rohrdurchbruches in der Lamelle kann beliebig sein (111,1V), da es keinen Einfluß auf die Leitschnitte hat. Daher kann auch die Größe und Form des Rohres im Wärmetauscher beliebig sein.2.3 Execution of the pipe penetration in the lamella and the pipes ! size and shape: i of the pipe opening in the lamella can be of any size (111.1V), since it has no influence on the leading cuts. Hence the size and shape of the pipe in the heat exchanger.

2.4 material der Lamelle Diese Art der Lamelle ist an kein bestimmtes 'lateral gebunden. Es kann daher jedes tiaterial gebraucht werden, das im Wärmetauscher verwendet wird. soFeE 3.) Se«taensprüche 3.1 Die Querlamelle für Wärmetauscher ist dadurch gekennzeichnet, daß Leitschnitte angebracht sind, wodurch die Durchströmungsgeschwindigkeit vermindert und ein höherer Wärmeübergang erzielt wird.2.4 material of the lamella This type of lamella is not attached to any particular 'laterally'. Any material that is used in the heat exchanger can therefore be used. soFeE 3.) Sayings 3.1 The cross lamella for heat exchangers is characterized in that guide cuts are made, which reduces the flow rate and a higher heat transfer is achieved.

3.2 Die Ouerlamelle mit Leitschnitten ist dadurch gekennzeichnet, daß die Ausführung der Lamelle beliebig sein kann, wie die Größe und Stärke, außerdem können Stabilisatoren und Randverstärkungen vorhanden sein.3.2 The outer lamella with guide cuts is characterized by that the execution of the lamella can be arbitrary, such as the size and strength, moreover stabilizers and edge reinforcements may be present.

3.3 Die Ouerlamelle mit Leitschnitten ist dadurch gekennzeichnet, daß die Form der Ausbauchung der Schnitte verschieden sein kann, benso kann die Ausbauchung nach ohen oder unten sein (I.). Dabei können die Ausbauchungen nur in einer Richtung sein (II.1), abwechselnd nach oben und unten (II.3). Die Lage der Schnitte kann zwischen, vor bzw. nach den Pöhrchen oder eine Kombination der t'öglichkeiten sein (III.). Der Winkel zwischen Schnittkante und Röhrchen kann beliebig sein. Die Größe der Schnitte ist abhängig von dem vorhandenen Platz und deren Anzahl.3.3 The Ouer lamella with guide cuts is characterized by that the shape of the bulge of the cuts can be different, so can the Bulging up or down (I.). The bulges can only be in one direction (II.1), alternating up and down (II.3). The location of the Cuts can be between, before or after the little tubes or a combination of the two be (III.). The angle between the cut edge and the tube can be arbitrary. the The size of the cuts depends on the available space and their number.
