Description

Die Erfindung betrifft einen Wärmeaustauscher entsprechend den Merkmalen des Oberbegriffes des Anspruches 1.The invention relates to a heat exchanger according to the features of the preamble of claim 1.

Aus der FR-A 2 297 396 ist ein Wärmeaustauscher bekannt geworden, bei dem Hohlelemente je an einander gegenüberliegenden Schmalseften eine positive bzw. eine negative schwalbenschwanzför-' mige Profilierung besitzen, wobei sie beim Eingreifen der Profilierung des vorangehenden Einzelelementes mit einem nachfolgenden Einzelelement eine größere Einzelplatte des Wärmetauschers bilden. Weiterhin sind plattenförmige Halterungen im Abstand voneinander angeordnet, welche an den einander gegenüberliegenden Innenflächen Nuten besitzen, in welche die Hohlelemente mit ihren Profilierungen eingesteckt sind. Es ergibt sich so eine Anordnung aus im Abstand voneinander angeordneten Hohlelementen. Ein erstes Wärmeaustauschmedium fließt durch die Zwischenräume zwischen den Hohlelementen. Ein zweites Wärmeaustauschmedium fließt durch die Hohlräume in denselben. Zur Zuführung dieses Wärmeaustauschmediums sind Hilfsprofile erforderlich, die eine entsprechende Umlenkung desselben bewirken. Die Einlaß- und Auslaßöffnungen liegen in den Halterungen.From FR-A 2 297 396 a heat exchanger has become known in which the hollow elements each have a positive or a negative dovetail-shaped profile on opposite narrow fissures, with a larger one when the profile of the preceding individual element engages with a subsequent individual element Form the single plate of the heat exchanger. Furthermore, plate-shaped holders are arranged at a distance from one another, which have grooves on the mutually opposite inner surfaces, into which the hollow elements with their profiles are inserted. The result is an arrangement of hollow elements spaced apart from one another. A first heat exchange medium flows through the spaces between the hollow elements. A second heat exchange medium flows through the cavities in the same. To supply this heat exchange medium, auxiliary profiles are required which cause the same to be deflected accordingly. The inlet and outlet openings are in the brackets.

Der Erfindung liegt die Aufgabe zugrunde, die Zuführung der Wärmeaustauschmedienströme unter Vermeidung von Umlenkungen derselben und damit den Wärmeaustausch zu verbessern, so daß sich die Abmessungen des Wärmeaustauschers bei gleicher Leistung verringern lassen.The invention has for its object to improve the supply of heat exchange media flows while avoiding deflections of the same and thus the heat exchange, so that the dimensions of the heat exchanger can be reduced with the same performance.

Die Lösung der Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Hauptanspruches.The solution to the problem results from the characterizing features of the main claim.

. Die Unteransprüche beschreiben bevorzugte Ausführungsformen.. The subclaims describe preferred embodiments.

Die beiliegenden Zeichnungen zeigen ein Beispiel der Erfindung und zwar:

  • Fig. 1 eine aufgeschnittene, schaubildliche Ansicht des Wärmeaustauschers;
  • Fig. 2 einen Schnitt längs der Linie II-II in Fig. 1;
  • Fig. 3 einen Schnitt längs der Linie III-III in Fig. 1.

The accompanying drawings show an example of the invention:
  • Figure 1 is a cut away, perspective view of the heat exchanger.
  • 2 shows a section along the line II-II in Fig. 1.
  • 3 shows a section along the line III-III in FIG. 1.
  • 4 shows an enlarged section through a first embodiment of a plate-shaped hollow element;

  • Fig. 7 on an enlarged scale a diagrammatic view from which the indentations which promote the swirling of the air can be seen.

Der Wärmeaustauscher besteht aus plattenförmigen Hohlelementen 1, die an einander gegenüberliegenden Schmalseiten eine positive bogenförmige Profilierung 2 bzw. eine negative bogenförmige Profilierung 3 besitzen. Die in Großserie z.B. als fortlaufendes Aluminiumprofil, von dem die gewünschte Länge abgeschnitten wird, hergestellten plattenförmigen Hohlelemente 1 werden nacheinander in eine der vorzugsweise aus Kunststoffmaterial bestehenden Stirnwände 8 und 9 einer Halterung in Führungsnuten 14 bzw. 16 eingeschoben. Anschließend wird die andere Stirnwand 8 bzw.9 mit ihren Führungsnuten 14 bzw. 16 auf die Anordnung aufgedrückt. Dabei greift dann jeweils eine positive Profilierung 2 eines Elementes in die negative Profilierung 3 des vorangehenden Hohlelementes 1 ein.The heat exchanger consists of plate-shaped hollow elements 1 which have a positive curved profile 2 or a negative curved profile 3 on opposite narrow sides. The in large series e.g. As a continuous aluminum profile, from which the desired length is cut off, plate-shaped hollow elements 1 produced are successively inserted into one of the end walls 8 and 9 of a holder, preferably made of plastic material, in guide grooves 14 and 16, respectively. The other end wall 8 or 9 is then pressed onto the arrangement with its guide grooves 14 or 16. A positive profile 2 of an element then engages in the negative profile 3 of the preceding hollow element 1.

Zwischen den Führungsnuten 14 und 16 sind Schlitze 10 angeordnet, die beim Einschieben der Hohlelemente 1 ein federndes Nachgeben der Stimwandabschnitte zwischen den Führungsnuten 14 und 16 ermöglichen und somit das Einschieben erleichtern.Slits 10 are arranged between the guide grooves 14 and 16, which enable a resilient yielding of the end wall sections between the guide grooves 14 and 16 when the hollow elements 1 are inserted and thus facilitate insertion.

Das zu behandelnde Wärmeaustauschmedium wird im Sinne der Pfeile 18 in die Zwischenräume zwischen den plattenförmigen Hohlelementen 1 eingeführt und im Sinne der Pfeile 19 wieder abgeführt. Da, wie aus Fig.1, linke Seite, ersichtlich, das Wärmeaustauschmedium auf die positive Profilierung 2 des ersten Hohlelementes trifft, ergibt sich eine entsprechende Vergrößerung der Strömerungsgeschwindigkeit. Durch schlitzförmige Einlaß- bzw. Auslaßöffnungen 21 wird im Sinne des Pfeiles 22 Kühlluft durch die plattenförmigen Hohlelemente 1 hindurchgeblasen.The heat exchange medium to be treated is introduced in the direction of arrows 18 into the spaces between the plate-shaped hollow elements 1 and removed again in the direction of arrows 19. Since, as can be seen from FIG. 1, left-hand side, the heat exchange medium meets the positive profiling 2 of the first hollow element, the flow velocity is correspondingly increased. Cooling air is blown through the plate-shaped hollow elements 1 through slot-shaped inlet or outlet openings 21 in the direction of arrow 22.

Die Oberseite 5 bzw. Unterseite 6 jedes der plattenförmigen Hohlelemente 1 wird von Stegen 7 überdrückt, durch welche einerseits die Stabilität der Hohlelemente wesentlich verbessert wird. Andererseits wird durch die vorbeistreichende Kühlluft Wärme aus den Stegen 7 entzogen.The top 5 or bottom 6 of each of the plate-shaped hollow elements 1 is pressed over by webs 7, by means of which on the one hand the stability of the hollow elements is significantly improved. On the other hand, heat is extracted from the webs 7 by the cooling air flowing past.

Durch die unmittelbare metallische Wärmeleitung zur Oberseite 5 bzw. zur Unterseite 6, die nicht durch Klebestellen od. dgl. unterbrochen ist, ergibt sich ein höherer Wirkungsgrad. Damit sind weniger Stege im Hohlraum notwendig, so daß der Strömungswiderstand und die Verstopfungsgefahr wesentlich geringer ist.The direct metallic heat conduction to the upper side 5 or to the lower side 6, which is not interrupted by adhesive points or the like, results in a higher efficiency. This means that fewer webs are required in the cavity, so that the flow resistance and the risk of clogging are significantly lower.

Als bevorzugtes Ausführungsbeispiel werden folgende Abmessungen angegeben:

  • - Abstand zwischen den Profilierungen 2 bzw. 3, 115 mm
  • - Länge des plattenförmigen Hohlelementes 235 mm
  • - Höhe des plattenförmigen Hohlelementes 8 mm
  • - Anzahlder Stege 7 bzw. der Luftführungskammem im plattenförmigen Hohlelement 18 bzw. 19.
The following dimensions are given as a preferred exemplary embodiment:
  • - Distance between the profiles 2 and 3, 115 mm
  • - Length of the plate-shaped hollow element 235 mm
  • - Height of the plate-shaped hollow element 8 mm
  • - Number of webs 7 or the air guide chambers in the plate-shaped hollow element 18 or 19.

Es wird also ein Aufbau eines Wärmeaustauschers ohne Klebearbeiten oder andere aufwendige Arbeitsvorgänge erreicht. Die plattenförmigen Hohlelemente 1 brauchen lediglich eingesteckt zu werden, wobei die Nuten 16, 18 etwas enger sind als dies der Höhe der plattenförmigen Hohlelemente 1 entspricht, so daß eine durch die Schlitze 10 geförderte elastische Aufbiegung und eine entsprechende Einspannung der plattenförmigen Hohlelemente erreicht wird. Der Wärmeübergang ist im Vergleich zu Wärmeaustauschern gleicher Größe erheblich verbessert.A heat exchanger is thus built up without adhesive work or other complex work processes. The plate-shaped hollow elements 1 only need to be inserted, the grooves 16, 18 being somewhat narrower than this corresponds to the height of the plate-shaped hollow elements 1, so that an elastic bend promoted by the slots 10 and a corresponding clamping of the plate-shaped hollow elements is achieved. The heat transfer is significantly improved compared to heat exchangers of the same size.

Durch den gegenseitigen Eingriff der Profilierungen 2, 3 wird eine hohe Stabilität des Gesamtaufbaus erreicht, so daß die Halterung in den Stirnwänden 8, 9 ausreicht. Außerdem ergibt sich eine glatte Oberfläche der zusammengesetzten Platten ohne Behinderung des Stromes des ersten Wärmeaustauschmediums.Through the mutual intervention of the profiling gene 2, 3 a high stability of the overall structure is achieved so that the bracket in the end walls 8, 9 is sufficient. In addition, there is a smooth surface of the assembled plates without obstructing the flow of the first heat exchange medium.

Die die Führungsnuten 14 bzw. 16 enthaltenden Stirnwände 8 und 9, welche vorzugsweise aus Kunststoffmaterial bestehen, besitzen Führungsbalken 23, welche durch schräg zur Längsachse der Stege 7 gestellte Platten 20 verbunden sind. Der in Richtung des Pfeiles 22 auftreffende Luftstrom wird durch die Platten 20 schräg auf die Stege 7 bzw. auf die Führungsstege 11 aufgeblasen, so daß eingangsseitig eine starke Verwirbelung der Luft stattfindet, die noch durch die Eindellungen 24, welche die Luft nach oben lenken, unterstützt wird.The end walls 8 and 9 containing the guide grooves 14 and 16, which preferably consist of plastic material, have guide beams 23 which are connected by plates 20 placed at an angle to the longitudinal axis of the webs 7. The air flow impinging in the direction of arrow 22 is inflated obliquely by the plates 20 onto the webs 7 or onto the guide webs 11, so that a strong swirling of the air takes place on the inlet side, which is still caused by the indentations 24 which direct the air upwards. is supported.

Entsprechende praktische Versuche haben ergeben, daß der Wärmeübergang zwischen den beiden Wärmeaustauschmedien durch diese Ausbildung erheblich verbessert wird, was den Bau kleinerer Wärmeaustauscher bei gleicher Leistung oder eine höhere Leistung bei gleich großen Wärmeaustauschern ermöglicht.Corresponding practical tests have shown that the heat transfer between the two heat exchange media is considerably improved by this design, which enables the construction of smaller heat exchangers with the same output or a higher output with the same size heat exchangers.

Anstelle einer einzigen Eindellung 24 können mehrere z.B. auch hälbkugelförmige Eindellungen im Abstand voneinander vorgesehen sein, die sich bis zur Mitte der Einzelplatte oder auch darüber hinaus erstrecken.Instead of a single indentation 24, several e.g. also hemispherical indentations can be provided at a distance from each other, which extend to the center of the single plate or even beyond.
