Abstract

Die Erfindung bezieht sich auf einen Verflüssiger für ein Kältemittel einer Fahrzeugklimaanlage, bei dem das Käl­ temittel durch in mehrere Kanäle unterteilte Flachrohre (10) und im Kreuzstrom hierzu Umgebungsluft längs zickzack- oder wellen­ förmig gefalteter Lamellen (2a,2b) geführt sind, die jeweils zwischen zwei benachbarten Flachrohren wärmeleitend angeordnet sind, wobei mehrere Flachrohre in Form einer serpentinenförmig gebogenen Rohrschlange (1a,1b) zusammenhängen und zwei Rohr­ schlangen (1a,1b) vorgesehen sind. Nach der Erfindung ist vorge­ sehen, daß die zwei, oder drei, oder mehr bis maximal sechs Rohrschlangen (1a,1b,...) demselben Kältemittelkreislauf in Parallelschaltung angehören und ineinander verschachtelt ange­ ordnet sind. The invention relates to a condenser for a refrigerant in a vehicle air conditioning system in which the cold by means of flat tubes (10) and To this end, cross-flow ambient air along zigzag or waves Folded slats (2a, 2b) are guided, each arranged in a heat-conducting manner between two adjacent flat tubes are, with several flat tubes in the form of a serpentine bent pipe coil (1a, 1b) and two pipe snakes (1a, 1b) are provided. According to the invention is pre see that the two, or three, or more to a maximum of six Pipe coils (1a, 1b, ...) in the same refrigerant circuit in Belong to parallel connection and nested in one another are arranged.
