Abstract
Description
Die vorliegende Erfindung betrifft einen Wärmetauscher, insbesondere einen Verdampfer für ein Kältegerät, wie etwa einen Haushaltskühl- oder -gefrierschrank, sowie ein Verfahren zu dessen Herstellung.The The present invention relates to a heat exchanger, in particular a Evaporator for a refrigeration device, such as a household refrigeration or freezer, and a method for its production.
Aus
Bei der Herstellung des Verdampfers muss streng darauf geachtet werden, dass das Kältemittelrohr auf der Trägerplatte exakt entsprechend dem Verlauf der Rinne des Stempels platziert wird. Wenn das Rohr nicht mittig in der Rinne zu liegen kommt, ergeben sich unterschiedliche Dicken der Bitumenschicht an einander gegenüberliegenden Seiten des Rohrs, oder die Bitumenschicht reißt beim Anformen an die Basisplatte und das Kältemittelrohr stellenweise auf. Wenn die Positionsabweichung so stark ist, dass das Rohr nicht mehr innerhalb der Rinne liegt, so wird es beim Andrücken des Stempels flach gequetscht und der Verdampfer so zerstört.at the production of the evaporator must be strictly that the refrigerant pipe on the carrier plate placed exactly according to the course of the trough of the punch becomes. If the tube does not come to rest in the middle of the gutter different thicknesses of the bitumen layer on opposite sides Side of the tube, or the bitumen layer ruptures during molding to the base plate and the refrigerant pipe in places. If the position deviation is so strong that the pipe is no longer inside the gutter, so it is when pressing the Stamp squeezed flat and the evaporator destroyed.
Der Hub des Stempels muss wenigstens so groß sein, dass die Bitumenschicht im Bereich zwischen den Mäandern des Kältemittelrohrs mit der Trägerplatte in Kontakt kommt. Wenn der Hub größer als hierfür unbedingt notwendig ist, wird das Bitumenmaterial in die Zwickel zwischen der im Querschnitt elliptischen Rohrleitung und der Trägerplatte getrieben. Das bekannte Verfahren ist daher nicht brauchbar, wenn anstelle der Bitumenplatte eine Platte aus einem hochwirksam wärmeisolierenden Material angeformt werden soll, da das Eindringen eines solchen Materials in die Zwickel den Wärmeaustausch zwischen dem Kältemittelrohr und der Basisplatte und damit die Effizienz des Verdampfers beeinträchtigen würde.Of the Stroke of the stamp must be at least as large that the bitumen layer in the area between the meanders of the refrigerant pipe with the carrier plate comes into contact. If the hub is larger than this necessarily is necessary, the bitumen material is in the gusset between the elliptical in cross-section pipe and the support plate driven. The known method is therefore not useful when instead of the bituminous plate a plate made of a highly effective heat-insulating Material to be formed, since the penetration of such material in the gussets the heat exchange between the refrigerant pipe and the base plate and thus the efficiency of the evaporator would affect.
Aufgabe der vorliegenden Erfindung ist, ein Verfahren zum Herstellen eines Wärmetauschers, das die Herstellung hochwertiger Wärmetauscher auch bei geringen Anforderungen an die Herstellungstoleranzen erlaubt, bzw. einen Wärmetauscher anzugeben, der mit einem solchen Verfahren herstellbar ist.task The present invention is a method for producing a Heat exchanger, the the production of high quality heat exchangers as well allowed with low demands on the manufacturing tolerances, or specify a heat exchanger, which can be produced by such a method.
Die Aufgabe wird erfindungsgemäße dadurch gelöst, dass das Formteil aus wärmeisolierendem Material von vornherein mit einer auf dessen Oberfläche verlaufenden, vorgeformten Rinne bereitgestellt wird, in welcher das Rohr platziert wird, bevor die Trägerplatte an der Oberfläche befestigt wird. Auch wenn die Krümmungswinkel an den diversen Biegungen des Rohrs geringfügig von entsprechenden Winkeln der Rinne abweichen, kann das Rohr durch leichtes elastisches Biegen noch ohne Schwierigkeiten in die Rinne eingefügt werden. Ein Zerquetschen des Rohrs zwischen dem Formteil und der Trägerplatte ist so ausgeschlossen.The Task is characterized according to the invention solved, that the molded part of heat-insulating Material from the outset with a surface running on the surface, preformed channel is provided, in which placed the tube is before the carrier plate on the surface is attached. Even if the bending angle at the various bends of the pipe slightly from corresponding angles the gutter can deviate the tube by slightly elastic bending be inserted into the gutter without difficulty. A crush the tube between the molding and the support plate is so excluded.
Vorzugsweise ist die Dicke des Rohrs senkrecht zu der Oberfläche des Formteils zunächst größer als die Tiefe der darin gebildeten Rinne, so dass das Rohr, auch wenn es am Boden der Rinne anliegt, ein Stück weit aus dieser herausragt. Wenn nun das Formteil und die Trägerplatte gegeneinander gedrückt werden, um wenigstens Teile der Oberfläche des Formteils mit der Trägerplatte in Kontakt zu bringen, wird gleichzeitig das Rohr zwischen der Trägerplatte und dem Formteil flachgedrückt, wodurch sich der Wärmeübergang zwischen der Platte und dem Rohr in erwünschter Weise verbessert.Preferably the thickness of the tube perpendicular to the surface of the molding is initially greater than the depth of the gutter formed in it, leaving the pipe, even if it rests on the bottom of the gutter, protrudes a bit far out of this. If now the molding and the support plate pressed against each other be at least parts of the surface of the molding with the support plate At the same time, the tube between the support plate is brought into contact and flattened the molding, which reduces the heat transfer between the plate and the tube is desirably improved.
Das Formteil kann einfach und wirtschaftlich durch Expandieren eines Kunststoffmaterials in einem Formwerkzeug hergestellt werden. Als zu expandierendes Kunststoffmaterial kommen insbesondere Polystyrol und Polyurethan in Betracht.The Molding can be easily and economically by expanding a Plastic material can be produced in a mold. When plastic material to be expanded is, in particular, polystyrene and polyurethane into consideration.
Um eine gute Isolationswirkung zu erzielen, ist ein hoher Porenanteil im expandierten Material wünschenswert; andererseits muss das expandierte Material eine zum Flachdrücken des Kältemittelrohrs ausreichende Festigkeit aufweisen. Bei einem Formteil aus Polystyrol hat sich eine Dichte von 30 bis 50 g/dm3, vorzugsweise ca. 40 g/dm3, als geeignet erwiesen.In order to achieve a good insulation effect, a high pore content in the expanded material is desirable; On the other hand, the expanded material must have sufficient strength for flattening the refrigerant pipe. In a molded article made of polystyrene, a density of 30 to 50 g / dm 3 , preferably about 40 g / dm 3 , has proved suitable.
Das Formteil und die Trägerplatte sind vorzugsweise durch Kleben, insbesondere mit Hilfe einer Klebefolie verbunden. Diese Klebefolie ist vorzugsweise am Formteil angebracht, da alternativ dazu an der Trägerplatte angebrachte Klebefolie jeweils an den vom Kältemittelrohr berührten Bereichen der Trägerplatte ausgespart sein müsste, um den Wärmeübergang zwischen Rohr und Trägerplatte nicht zu beeinträchtigen.The Molding and the carrier plate are preferably by gluing, in particular by means of an adhesive film connected. This adhesive film is preferably attached to the molding, as an alternative to the support plate attached adhesive film respectively at the areas touched by the refrigerant pipe the carrier plate should be left out, to the heat transfer between tube and carrier plate not to interfere.
