Abstract
Es handelt sich um einen Kreuzstrom-Wärmetauscher für Kondensationswäschetrockner derjenigen Art, die Gegenstand der DE 19838525 A1 ist. DOLLAR A Um die Kühlleistung der zu einem Wärmetauscher-Plattenpaket (10) geschichteten Wärmetauscherplatten zu erhöhen, die jeweils aus zwei aus einer Folie geformten Plattenteil (16 bzw. 18) gebildet sind und wenigstens einen Feuchtluftkanal (14) enthalten, wird vorgeschlagen, zur Bildung von zwischen den Wärmetauscherplatten (12) den Feuchtluftkanal (14) kreuzenden Kühlluftkanälen (42) wenigstens an die Außenseite des einen Plattenteils (18) durch Tiefziehen offene, taschenartige Kühllamellen (32) anzuformen, an denen sich eine benachbarte Wärmetauscherplatte (12) abstützt.It is a cross-flow heat exchanger for condensation tumble dryers of the type which is the subject of DE 19838525 A1. DOLLAR A In order to increase the cooling capacity of the heat exchanger plates stacked to form a heat exchanger plate pack (10), which are each formed from two plate parts (16 or 18) formed from a film and contain at least one moist air channel (14), it is proposed to form to form, by deep-drawing, open, pocket-like cooling fins (32), at least on the outside of the one plate part (18), between the heat exchanger plates (12) crossing the moist air duct (14), on which an adjacent heat exchanger plate (12) is supported.
Description
Die Erfindung betrifft mit den Merkmalen des Oberbegriffs des Anspruchs 1 sowie ein Verfahren zu dessen Herstellung gemäß den Merkmalen des, Oberbegriffs des Anspruchs 6.The invention relates to the features the preamble of claim 1 and a method for its production according to the characteristics des, preamble of claim 6.
Aus der
Der Erfindung liegt die Aufgabe zugrunde, eine Weiterbildung eines derartigen Kreuzstrom-Wärmetauschers einen Kreuzstrom-Wärmetauscher für Kondensationswäschetrockner bereitzustellen, bei der sich bei einer den Abmessungen des Plattenpaketes des bekannten Kreuzstrom-Wärmetauschers entsprechenden Dimensionierung des Plattenpaketes eine Steigerung, bzw. trotz geringeren Abmessungen desselben, eine adäquate bzw. gleiche Kühlleistung erzielen lässt. Dabei soll der Wärmetauscher nach wie vor einfach herstellbar sein.The invention has for its object a Development of such a cross-flow heat exchanger is a cross-flow heat exchanger for condensation tumble dryers To be provided in the case of the dimensions of the plate pack of the known cross-flow heat exchanger appropriate dimensioning of the plate pack an increase, or despite the smaller dimensions of the same, an adequate or the same cooling capacity can be achieved. The heat exchanger should still be easy to manufacture.
Ein derartiger Kreuzstrom-Wärmetauscher zeichnet sich erfindungsgemäß durch die Merkmale des Anspruchs 1 aus. Ein erfindungsgemäßes Herstellungsverfahren ergibt sich aus dem Anspruch 6.Such a cross-flow heat exchanger draws according to the invention the features of claim 1. A manufacturing method according to the invention results from claim 6.
Im Unterschied zur Wärmetauscherkonstruktion
gemäß
Die Stege sind erfindungsgemäß durch zum Feuchtluftkanal offene Taschen gebildet, in denen sich kein Kondensat anstauen kann und deren Stegwandteile demgemäß Kühlflächen bilden.The webs are according to the invention open pockets to the moist air duct are formed, in which there is no Can accumulate condensate and the wall wall parts accordingly form cooling surfaces.
Der Wirkungsgrad des Wärmetauschers lässt sich dabei noch entscheidend dadurch verbessern, dass der Feuchtluftkanal als Flachrohr ausgebildet ist (Anspruch 2) und vorzugsweise oberer und unterer Kanalwandteil des Feuchtluftkanals im Querschnitt gewellt ausgebildet sind und beide Wellenlinien zueinander parallel verlaufen (Anspruch 5).The efficiency of the heat exchanger can be thereby still significantly improve that the moist air duct is designed as a flat tube (claim 2) and preferably upper and corrugated cross section of the lower duct wall part of the moist air duct are formed and both wavy lines run parallel to each other (Claim 5).
Die Länge der sich quer zum Feuchtluftkanal erstreckenden Stege kann ungefähr der Breite des als Flachrohr ausgebildeten Feuchtluftkanals entsprechen. Bevorzugt wird jedoch eine Steglänge, die lediglich einem Bruchteil der Breite des Feuchtluftkanals entspricht, wobei die Stege in Längsrichtung des Flachrohres zweckmäßig auf Lücke zueinander versetzt angeordnet sind (Anspruch 3).The length of the extending across the moist air duct Jetties can roughly correspond to the width of the humid air duct designed as a flat tube. However, a web length is preferred, which only corresponds to a fraction of the width of the moist air duct, the webs in the longitudinal direction of the flat tube appropriately Gap to each other are arranged offset (claim 3).
Eine derartige Steganordnung ermöglicht eine weitere wesentliche Verbesserung der Strömungsverhältnisse, indem die Stege an ihren Steglängsseiten nach außen schwach konvex zu krümmen sind (Anspruch 4). Zur Fertigung von Plattenteilen aus thermoplastischer Kunststofffolie empfiehlt es sich, in eine solche Folie durch thermische Umformung an zwei Folienhälften jeweils eine Konfiguration zur Bildung mindestens einer von zwei Hälften eines Feuchtluftkanals sowie an die Oberseite der oberen Hälfte desselben in Kanallängsrichtung, im Abstand voneinander und sich zum Feuchtluftkanal quer erstreckend, eine Vielzahl von Steg- bzw. taschenartigen Kühllamellen durch Tiefziehen anzuformen, danach die beiden Folienhälften durch Falten der Kunststofffolie derart auf Deckung zu bringen, dass deren Konfigurationen sich zum Feuchtluftkanal ergänzen und schließlich die freien Längsrandteile beider Folienhälften miteinander z.B. durch Kleben oder Schweißen dicht zu verbinden (Anspruch 6). Such a web arrangement enables one further significant improvement in flow conditions by adding the webs their long sides outward slightly convex to curve are (claim 4). For the production of plate parts from thermoplastic Plastic film is recommended to be thermoformed into such a film on two film halves one configuration each to form at least one of two halves a humid air duct and on the top of the upper half of the same in the longitudinal direction of the channel, in Distance from each other and extending transversely to the moist air duct, a variety of web or pocket-like cooling fins by deep drawing to form, then the two film halves by folding the plastic film in such a way that their configurations change to Add moist air duct and finally the free longitudinal edge parts of both foil halves with each other e.g. to be sealed by gluing or welding (claim 6).
