Description
Die Erfindung betrifft einen Scheibenverdampfer mit einer Vielzahl aus jeweils zwei prägeprofilierten Blechscheiben zusammengefügten, U-förmige Strömungskanäle aufweisenden Wärmetauschelementen, die mittels aneinander anliegenden Ausprägungen der Blechscheiben Sammelkanäle bilden, die in Längsrichtung mittels wenigstens einer Trennwand unterteilt sind und von welchem einer mit einem Einspritzrohr versehen ist, das mittels eines Seitenteils und einer Trennwand gehalten ist.The The invention relates to a disk evaporator with a plurality of two embossed profiles each Sheet metal discs assembled, U-shaped Having flow channels Heat exchange elements, form by means of abutting forms of sheet metal discs collecting channels, the longitudinal are divided by at least one partition and from which one is provided with an injection tube by means of a side part and a partition is held.
Um

Abführanschluß für einen
derartigen Scheibenverdampfer auf der gleichen Stirnseite anordnen
zu können,
ist es bekannt (
Bei
Scheibenverdampfern der eingangs genannten Art (
Derartige Scheibenverdampfer werden zu einem Paket montiert und dann als Ganzes in einen Ofen eingebracht und dort verlötet.such Disk evaporators are assembled into a package and then as a whole placed in a furnace and soldered there.
Der Erfindung liegt die Aufgabe zugrunde, einen Scheibenverdampfer so zu gestalten, daß auch das Einspritzrohr mit den Wärmetauschelementen des Verdampfers vormontiert und dann mit diesen in einem Arbeitsgang verlötet werden kann, ohne daß die Gefahr von Undichtheiten insbesondere an dem Anschluß zu dem Seitenteil bestehen.Of the Invention is based on the object, a disk evaporator so to shape that too Injection tube with the heat exchange elements of Vaporizer pre-assembled and then with these in one operation soldered can be without the Danger of leaks, especially at the connection to the Seitenteil exist.
Diese Aufgabe wird dadurch gelöst, daß das Einspritzrohr an dem Seitenteil kraft- und formschlüssig gehalten und mittels der Trennwand in Längsrichtung verschiebbar geführt ist.These Task is solved by that the injection pipe held non-positively and positively on the side part and by means of Partition in the longitudinal direction slidably guided is.
Die Erfindung berücksichtigt, daß das Paket aus den Wärmetauschelementen und dazwischen angeordneten Wellrippen beim Löten in einem Lötofen etwas schrumpft, da die Lötschicht zwischen den einzelnen Wärmetauschelementen wegschmilzt. Da das Einspritzrohr fest in dem Seitenteil fixiert ist, jedoch sich relativ zu der Trennwand verschieben kann, bleibt die relative Lage des Einspritzrohrs zu dem Seitenteil erhalten, so daß mit Sicherheit die Gefahr einer Undichtheit in diesem Bereich vermieden ist. Nach dem Verlöten ist selbstverständlich das Einspritzrohr auch gegenüber der Trennwand nicht mehr verschiebbar.The Considered in the invention, that this Package from the heat exchange elements and interposed corrugated fins during soldering in a solder oven a little shrinks, as the solder layer between the individual heat exchange elements melts away. Since the injection tube firmly fixed in the side part is, but can move relative to the partition remains get the relative position of the injection tube to the side part, so that with Safety the risk of leakage in this area is avoided. After soldering is self-evident the injection pipe also opposite the partition no longer movable.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß das Einspritzrohr mit einem Außenkonus versehen ist, der in einen Durchzug des Seitenteils eingesteckt ist. Vorteilhaft wird dabei vorgesehen, daß der Durchzug des Seitenteils mit einem dem Außenkonus des Einspritzrohres angepaßten Innenkonus versehen ist. Dadurch wird erreicht, daß das Einspritzrohr exakt in axialer Richtung ausgerichtet ist.In Another embodiment of the invention, it is provided that the injection tube with an outer cone is provided, which is inserted in a passage of the side part is. Advantageously, it is provided that the passage of the side part with an outer cone the injection tube adapted inner cone is provided. This ensures that the injection tube exactly in aligned in the axial direction.
In weiterer Ausgestaltung der Erfindung wird vorgesehen, daß das Einspritzrohr sich bis zum Ende des Sammelkastens erstreckt und im Bereich seines Endabschnittes mit den einzelnen Wärmetauschelementen zugeordneten Austrittsöffnungen versehen ist. Auf diese Weise ist es möglich, den in diesem Endabschnitt befindlichen Wärmetauschelementen das Kältemittel mit weitgehend gleichmäßiger Verteilung zuzuführen. Diese Ausbildung ist auch von Vorteil, wenn das Einspritzrohr in anderer Weise an einem Seitenteil und/oder einer Trennwand gehalten ist.In Another embodiment of the invention, it is provided that the injection tube extends to the end of the collecting tank and in the region of its end portion with the individual heat exchange elements associated outlet openings is provided. In this way it is possible that in this end section located heat exchange elements the refrigerant to be supplied with a largely uniform distribution. These Training is also beneficial if the injection tube in another Way is held on a side part and / or a partition wall.
