Description
Beschreibung: Gegenstromwärmeiauscher Description: Counterflow heat exchanger
Wärmetauscher der übliche Bauart, weiche beispielsweise für die kontrollierte Wohngslüftung eingesetzt werden sind entweder Kreuzstrom-Plattenwärmetauscher oder Gegenstrom-Kanalwärmetauscher. Kreuzstrom-Plattenwärmetauscher (z.B. CH 588 672) besitzen, bedingt durch ihren Aufbau, einen relativ geringen Wärmerückgewinnungsgrad. Dieser kann durch Hintereinanderschalten zweier Wärmetauscher erhöht werden. Allerdings entstehen dann durch viermaliges Umlenken der Luftströme enorm hohe Druckverluste. Die hohe Anzahl mechanisch beanspruchter Verbindungsfugen macht eine dichte Trennung der Luftströme schwierig. Geräte mit derartigen Wärmetauschern weisen hohe Leckraten auf. Um die Platten solcher Wärmetauscher zu trennen werden Abstandshalter eingesetzt, an denen leicht Verschmutzungen hängenbleiben, welche schwierig wieder zu entfernen sind.Heat exchangers of the usual design, which are used for example for controlled ventilation in homes, are either cross-flow plate heat exchangers or counter-flow channel heat exchangers. Cross-flow plate heat exchangers (e.g. CH 588 672) have a relatively low heat recovery rate due to their design. This can be increased by connecting two heat exchangers in series. However, this results in extremely high pressure losses due to the four-fold diversion of the air flows. The large number of mechanically stressed connecting joints makes it difficult to separate the air flows tightly. Devices with such heat exchangers have high leak rates. To separate the plates of such heat exchangers, spacers are used, which easily attract dirt and are difficult to remove.
Zur Steigerung des Wärmerückgewinnungsgrades werden profilierte Platten , eingesetzt, was durch starke Verwirbelungen hohe Druckverluste zur Folge hat.To increase the heat recovery rate, profiled plates are used, which results in high pressure losses due to strong turbulence.
Gegenstrom-Kanalwärmetauscher der üblichen Bauart werden aus s-förmig übereinandergelegten fortlaufenden profilierten Streifen mit überhöhtem Trapezprofi! ( DE 43 33 904 ) gefertigt, was einen erheblichen Aufwand an entsprechenden Sondermaschinen mit sich bringt. Alternativ werden tiefgezogene Kunststoffpiatten mit derartiger Profilierung verwendet, welche allerdings mit einer zusätzlichen, piatzaufwändigen seitlichen Arretierung versehen sein müssen, um ein Verrutschen der Profilplatten und somit eine Reduzierung der Wärmetauscherfläche zu verhindern.Counterflow channel heat exchangers of the usual design are made from continuous profiled strips with raised trapezoidal profiles laid on top of one another in an S shape! (DE 43 33 904), which requires a considerable amount of special machinery. Alternatively, deep-drawn plastic plates with this type of profile are used, although these must be provided with an additional, space-consuming lateral locking mechanism to prevent the profile plates from slipping and thus reducing the heat exchanger surface.
Eine Führung der Medienströme zwischen gewellten Profilplatten wird auch in DE-PS 8 54 363 erläutert. Bei Profilen ab einer bestimmten Baubreite besteht jedoch die Möglichkeit des ineinanderrutschens der Platten. Bei den letzten beiden Bauweisen ist es vorgesehen, daß das Medium in der jeweiligen Profilebene zwischen den Kanälen überströmen kann. Da aber durch die Art des Ein- bzw. Auslasses eine Hauptströmungsrichtung schräg zu den Profilkanten entsteht wird ein Teil der Profilfläche kaum oder überhaupt nicht genutzt.The routing of media flows between corrugated profile plates is also explained in DE-PS 8 54 363. However, with profiles of a certain width or more, there is a possibility of the plates slipping into each other. The last two designs allow the medium to flow between the channels in the respective profile plane. However, since the type of inlet and outlet creates a main flow direction at an angle to the profile edges, a part of the profile surface is hardly used or not used at all.
Problem:Problem:

Der im Schutzanspruch 1 angegebenen Erfindung liegt das Problem zugrunde einen Wärmetauscher zu schaffen, der aus einem.Grundelement zu variabler Größe zusammengesetzt werden kann. Um die Wärmetauscherfläche konstant zu halten ist es von Bedeutung, daß sich die einzelnen Elemente gegeneinander nicht verschieben können. Desweiteren soll es möglich sein, die einzelnen Elemente gegenseitig, sowie den Wärmetauschkörper insgesamt hinreichend und ohne großen Aufwand abdichten zu können.The invention specified in claim 1 is based on the problem of creating a heat exchanger that can be assembled from a basic element of variable size. In order to keep the heat exchanger surface constant, it is important that the individual elements cannot move against each other. Furthermore, it should be possible to seal the individual elements against each other and the heat exchanger body as a whole sufficiently and without great effort.
Lösung:Solution:
Gelöst werden die aufgeführten Probleme durch die in Schutzanspruch 1 angeführte Profilierung, sowie die in Schutzanspruch 2 erläuterten flächigen Abschlüsse der Platten. Durch diese Merkmale ist es möglich, daß die Wärmetauscherplatten, je nach Flächenbedarf, in einfacher Art und Weise übereinandergestapelt und an den seitlichen Berührungsflächen verbunden (schweißen, kleben...) werden können. Die Profilierung verhindert einerseits ein Ineinanderrutschen der Platten und sorgt andererseits für eine hohe Stabilität des Paketes. Weiterhin entstehen durch die immer wiederkehrenden Überhöhungen im Profil Abschnitte von mehreren Kanälen. So kann das Medium zwar in diesen Abschnitten, aber nicht über die ganze Profilbreite überströmen, was eine insgesamt günstigere Ausnutzung der Profilfläche bewirkt.The problems listed are solved by the profiling mentioned in claim 1 and the flat ends of the plates explained in claim 2. These features make it possible for the heat exchanger plates to be easily stacked on top of each other and connected (welded, glued...) at the lateral contact surfaces, depending on the area required. The profiling prevents the plates from sliding into each other and ensures that the package is highly stable. Furthermore, the recurring elevations in the profile create sections with multiple channels. This means that the medium can flow in these sections, but not across the entire width of the profile, which results in a more favorable use of the profile surface overall.
Beim Einbau des Paketes in ein Gehäuse kann dieses seitlich mit Weichdichtungen, sowie an den Übergangsstellen der Ein-und Auslässe mit Dichtungsmasse abgedichted werden.When installing the package in a housing, it can be sealed on the sides with soft seals, and at the transition points of the inlets and outlets with sealing compound.

In Figur 1 ist zu sehen, wie sich aufeinanderfolgende Platten in ihren Profilen abstützen, und Abschnitte mit mehreren Kanälen ausbilden.Figure 1 shows how successive plates support each other in their profiles and form sections with multiple channels.
Die seitlich sich berührenden Flächen zweier Platten werden miteinander verschweißt oder verklebt. Das Plattenpaket wird zusammen mit Dichtungen in ein Gehäuse eingelegt.The surfaces of two plates that touch each other at the sides are welded or glued together. The plate package is inserted into a housing together with seals.
Die 3D-Ansicht einer Profilplatte in Figur la zeigt, Flächen an den Stirnseiten des Profiles über welche die Medienströme auf die Kanäle verteilt werden. Die durch das Abknicken nach oben entstandene seitliche Fläche wird mit der nächsthöheren Platte verbunden. Analog dazu wird die nach unten abgewinkelte Fläche mit der nächsttieferen Platte verbunden. Somit kann ein eventuell seitlich überströmendes Medium immer nur in die übernächste Ebene gelangen, „wo es auf das Medium des gleichen Zustandes trifft.The 3D view of a profile plate in Figure 1a shows surfaces on the front sides of the profile over which the media flows are distributed to the channels. The side surface created by bending upwards is connected to the next higher plate. In a similar way, the surface angled downwards is connected to the next lower plate. This means that any medium that may overflow sideways can only ever reach the next level, "where it meets the medium of the same state.
In Figur 2 wird verdeutlicht wie die Medienströme durch den Plattenstapel verlaufen.Figure 2 shows how the media flows through the disk stack.
Im Schnitt ist die Kanalanordnung, sowie die Verteilung der Medien auf die Kanäle und die Trennung der Medien durch die Profiipiatten zu sehen.The cross-section shows the channel layout, as well as the distribution of the media across the channels and the separation of the media by the profile plates.
Figur 3 zeigt den in ein Gehäuse(4) eingebauten Wärmetauscher, die Ein-und Ausströmöffnungen (5) sowie die Abdichtung (6) im Übergangsbereich zwischen Gehäuse und Wärmetauscher, in dieser Zusammenstellung kann der Wärmetauscher in ein Zentralgerät einer Wärmerückgewinnungsanlage für Gebäude eingebaut werden.Figure 3 shows the heat exchanger installed in a housing (4), the inlet and outlet openings (5) and the seal (6) in the transition area between the housing and the heat exchanger. In this configuration, the heat exchanger can be installed in a central unit of a heat recovery system for buildings.
