Description

`Verbindung bei Einrohransehlüssen von Kältemaschinenverdampfern Die Erfindung betrifft eine Verbindung von Ein- rohranschlüssen von Kältemaschinenverdampfern zwischen dem Anschlußrohr aus Aluminium oder einer Aluminiumlegierung des Verdampfers, dem Saurohr aus Kupfer und dem Kapillarrohr aus Kupfer. Durch F i g. 5 und 6 der USA.-Patentschrift 2 760 346 ist bereits eine Verbindung dieser Art be- kanntgeworden. Es handelt sich dabei um einen so- genannten Einrohranschluß. Das vom Verdampfer kommende Aluminiumabsauarohr ist mit einem aus Kupfer bestehenden Rohrzwischenstück an dessen einem Ende stumpfverschweißt. Aus dem anderen Ende dieses Zwischenstücks ist das kupferne Kapil- larrolir seitlich tierausgeführt. Zugleich ist ein kupfernes Anschlußrohr, das zum Kompressor führt, in das Zwischenstück hineingesteckt. Alle drei Teile sind zusammen Bartverlötet. v Dabei müssen allerdings zwei Verbindungsstellen in Kauf genommen werden, die noch dazu zwei ver- schiedenartige Arbeitsgänge, nämlich Hartlöten und Stumpfschweißen, erforderlich machen. Der Erfindung liegt die Aufgabe zugrunde, eine kostensparende und sichere Verbindung der genann- ten drei Elemente herbeizuführen. Diese Aufgabe wird erfindungsgemäß dadurch ge- löst, daß das Kupfersaugrohr und das Kupferkapillar- rohr an ein und derselben Stelle in das Aluminium- anschlußrohr hineinragen und durch ein Klebemittel mit letzterem verbunden sind. Ein Ausführungsbeispiel der Erfindung ist in der Zeichnunu, dargestellt und wird im folgenden näher beschrieben. Es zeigt .-X li b. 1 einen Schnitt durch die Klebeverbindung, A b b. ' ' den Schnitt A -A aus A b b. 1. Das Ktipferkapillarrolir 1 wird im Inneren des zum Aluminiumverdampfer führenden Aluminiumabsaug- rohres 5 Geführt. Die dariestellte Herausführungsstelle des Kupfer- kapillarrohres 1 liegt an der Kompressorseite. In das auf,eweitete Ende des Aluminiumabsaugrohres 5 wird das zum Kompressor führende Kupferabsaug- rohr 6 und das herauszuführende Kapillarrohr 1 ein- gepaßt und verklebt. Die Verbindungsstellen zwischen den Teilen ver- schiedener Werkstoffe brauchen nicht gegen Kontakt- korro;ion geschützt zu werden, weil die isolierende Klebstoffschicht 8 einen elektrischen Kontakt zNvi- schen den beiden Werkstoffen verhindert. Die üblichen aushärtenden Metallklebestoffe haben ferner die Eigenschaft. -wringe Ver:ormum-,en auf- nehmen zu können. Das trifft beispielsweise auch bei verschiedenen in der Wärme aushärtbaren Zwei- komponentenklebern zu, die aus einem Bindemittel und einem Härter bestehen. Durch den Fortfall der zweiten Verbindun-sstelle und durch den Ersatz des Schweißens bzw. Hart- lötens durch Kleben wird eine wesentliche Verbilli- gung der Herstellungskosten der Kälteaggregate erreicht. `Connection with single pipe connections from Chiller evaporators The invention relates to a connection of pipe connections of refrigeration machine evaporators between the connecting pipe made of aluminum or an aluminum alloy of the evaporator, the Acid tube made of copper and the capillary tube Copper. By F i g. 5 and 6 of U.S. Patent 2 760 346 a connection of this type is already became known. It is such a called one-pipe connection. That from the vaporizer coming aluminum exhaust pipe is made with one Existing copper pipe adapter on its butt welded at one end. From the other The end of this intermediate piece is the copper cap- larrolir sideways animal execution. At the same time is a copper connection pipe leading to the compressor, inserted into the intermediate piece. All three parts are beard soldered together. v However, there must be two connection points be accepted, which also have two divide-like operations, namely brazing and Make butt welding necessary. The invention is based on the object of a cost-saving and secure connection of the named ten to bring about three elements. This object is achieved according to the invention solves that the copper suction tube and the copper capillary tube in one and the same place in the aluminum connecting pipe protrude and through an adhesive are associated with the latter. An embodiment of the invention is in Drawing, shown and will be described in more detail below described. It shows .-X li b. 1 a section through the adhesive connection, A b b. ' ' the section A -A from A b b. 1. The Ktipferkapillarrolir 1 is inside the for Aluminum evaporator leading aluminum suction tube 5 guided. The depicted exit point of the copper capillary tube 1 is on the compressor side. In the on, widened end of the aluminum suction pipe 5 the copper suction pipe leading to the compressor tube 6 and the capillary tube 1 to be led out fitted and glued. The connection points between the parts different materials do not need to protect against contact corro; ion to be protected because the insulating Adhesive layer 8 an electrical contact zNvi- between the two materials prevented. Have the usual hardening metal adhesives furthermore the property. -wringe Ver: ormum-, en on- to be able to take. This also applies to, for example different thermosetting two- component adhesives that consist of a binder and a hardener. By eliminating the second connection point and by replacing welding or hard soldering by gluing is an essential the production costs of the refrigeration units achieved.
