Description

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

Wärmeaustauscher, z.B. Kondensationswärmetauscher, werden in großen Stückzahlen, z.B. für Wäschetrockner benötigt, wobei größere hohle Einzelplatten im Abstand voneinander angeordnet werden. Durch den Freiraum zwischen den Platten wird z.B. die stark feuchtigkeitshaltige Prozeßluft ge­führt. Durch die Hohlräume in den Platten wird Kühlluft geblasen. Die Oberfläche der Platten bilden Kondensations­flächen, an denen sich die in der Prozeßluft enthaltene Feuchtigkeit niederschlägt.Heat exchangers, e.g. Condensation heat exchangers are used in large quantities, e.g. for tumble dryers, with larger hollow individual plates are arranged at a distance from each other. The space between the plates makes e.g. the highly moisture-laden process air. Cooling air is blown through the cavities in the plates. The surface of the plates form condensation surfaces on which the moisture contained in the process air condenses.

Da physikalisch gesehen der Wärmeübergang von der Kühlluft­seite prozeßbestimmend ist, gibt es derzeit neben den glat­ten Hohlräumen zusätzlich eingeklebte Aluminiumblech­streifchen. Mit der Einklebung von zusätzlichen Wärme­tauscherflächen auf der Kühlseite erhöht man zwar den Wir­kungsgrad, muß aber den fertigungstechnischen Nachteil einer Verklebung in Kauf nehmen. Auch ist die Wärmeablei­tung solcher Zusatzflächen an der Klebestelle gehemmt, so daß nach derzeitigem Stand der Klebetechnologie sehr viele Zusatzflächen eingeklebt werden müssen, was zu einem hohen Strömungswiderstand führt und wodurch die Gefahr des Ver­ stopfens durch nicht verbreitbare Verunreinigungen der Kühlluft wesentlich vergrößert wird. Bei einer Lebensdauer von mindestens 10 Jahren ist eine Veränderung der Klebe­stellen nicht auszuschließen.Since the heat transfer from the cooling air side is physically decisive for the process, there are currently also glued-in aluminum strips in addition to the smooth cavities. By gluing additional heat exchanger surfaces on the cooling side, the efficiency is increased, but the manufacturing disadvantage of gluing has to be accepted. Also, the heat dissipation of such additional surfaces is inhibited at the gluing point, so that, according to the current state of adhesive technology, a large number of additional surfaces have to be glued in, which leads to a high flow resistance and thereby the risk of ver plug is significantly enlarged by impurities of the cooling air that cannot be spread. With a lifespan of at least 10 years, a change in the gluing points cannot be ruled out.

Der Erfindung liegt nun die Aufgabe zugrunde, einen Wärme­austauscher der in Rede stehenden Art so zu verbessern, daß ein Aufbau aus in Masserproduktion hergestellten Ein­zelteilen möglich wird und daß der Wärmeaustausch so ver­bessert wird, daß ein befriedigendes Ergebnis auch bei kleineren und kompakteren Wärmeaustauschern erreicht wird.The invention is based on the object of improving a heat exchanger of the type in question in such a way that a build-up of mass-produced individual parts is possible and that the heat exchange is improved in such a way that a satisfactory result is achieved even with smaller and more compact heat exchangers.

Die Lösung der Aufgabe ergibt sich aus den kennzeichnenden Merkmalen des Hauptanspruches. Die Unteransprüche beschrei­ben bevorzugte Ausführungsformen.The solution to the problem results from the characterizing features of the main claim. The subclaims describe preferred embodiments.

  • Figure 2 is a section along the line II-II in Figure 1;
  • Figure 3 is a section along the line III-III in Figure 1;

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 bestehende Stirn-­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. Zwischen den Füh­rungsnuten 14 und 16 sind Schlitze 10 angeordnet, die beim Einschieben der Hohlelemente 1 ein federndes Nachgeben der Stirnwandabschnitte zwischen den Führungsnuten 14 und 16 ermöglichen und somit das Einschieben erleichtern.The heat exchanger consists of plate-shaped hollow elements 1 which have a positive arc-shaped profile 2 or a negative arc-shaped profile 3 on opposite narrow sides. The plate-shaped hollow elements 1, which are produced in large series, for example as a continuous aluminum profile, from which the desired length is cut off, are successively placed in one of the end walls 8 and 9, preferably made of plastic material, of a holder in guide grooves 14 or 16 inserted. 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. Slots 10 are arranged between the guide grooves 14 and 16, which enable the end wall sections between the guide grooves 14 and 16 to yield resiliently 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 the arrows 18 into the spaces between the plate-shaped hollow elements 1 and removed again in the direction of the arrows 19. Since, as can be seen from FIG. 1, left-hand side, the heat exchange medium meets the positive profile 2 of the first hollow element, there is a corresponding increase in the flow rate. Cooling air is blown through the plate-shaped hollow elements 1 through slot-shaped inlet or outlet openings 21 in the direction of the 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, on the one hand, by which 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 Luftführungskammern 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 guiding 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 ent­ sprechende 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 an ent speaking 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.Due to the mutual engagement of the profiles 2, 3, a high stability of the overall structure is achieved, so that the holder 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.Appropriate practical tests have shown that the heat transfer between the two heat exchange media is significantly improved by this training, 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 halbkugelförmige 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 beyond.
