Die Erfindung betrifft einen Wärmetauscher, insbesondere einen Kondensator für eine Kraftfahrzeug-Klimaanlage, gemäß dem Oberbegriff des Anspruchs 1.The invention relates to a heat exchanger, in particular a capacitor for a motor vehicle air conditioning system, according to the preamble of the claim 1.

Bei herkömmlichen Wärmetauschern sind die Sammelkästen üblicherweise mittels eingesetzter Deckel seitlich verschlossen.In conventional heat exchangers, the collection boxes are common laterally closed by means of inserted lid.

Ein derartiger Wärmetauscher lässt jedoch noch Wünsche offen.However, such a heat exchanger still leaves something to be desired.

Es ist Aufgabe der Erfindung, einen verbesserten Wärmetauscher zur Verfügung zu stellen.It is an object of the invention to provide an improved heat exchanger to deliver.

Diese Aufgabe wird gelöst durch einen Wärmetauscher mit den Merkmalen des Anspruchs 1. Vorteilhafte Ausgestaltungen sind Gegenstand der Unteransprüche.This object is achieved by a heat exchanger with the features of claim 1. Advantageous embodiments are the subject of the dependent claims.

Erfindungsgemäß ist ein Wärmetauscher vorgesehen mit zwei Sammelkästen, in welche die Enden von Rohren, insbesondere von Flachrohren, eingeführt sind, wobei Sammelkästen stimseitig jeweils von Deckeln verschlossen sind, und mindestens ein Deckel eine Aufnahme für die Enden eines Sammelkastens aufweist. Hierbei ist der Deckel von der Stirnseite auf den Sammelkasten aufgesetzt, d.h. der Deckel ist größer als die Stirnseite des Sammelkastens ausgebildet.According to the invention, a heat exchanger is provided with two collecting tanks, in which the ends of tubes, in particular of flat tubes, introduced are, with collecting boxes each end closed by lids are, and at least one cover a receptacle for the ends of a Has collecting box.

Vorzugsweise weist der Deckel eine Öffnung auf, durch welche die das Wärmetauschermedium dem Wärmetauscher zugeführt oder aus ihm abgeleitet werden kann. Dabei ist die Öffnung bevorzugt stufenförmig ausgebildet, so dass beispielsweise ein Rohr bis zu einem vorgegebenen Anschlag, welcher durch eine Stufe gebildet wird, eingeführt werden kann.Preferably, the lid has an opening through which the Heat exchanger medium supplied to the heat exchanger or derived from it can be. In this case, the opening is preferably stepped, such that, for example, a pipe up to a predetermined stop, which is formed by a step, can be introduced.

Der kleinste Durchmesser der Öffnung entspricht vorzugsweise dem Innendurchmesser eines in die Öffnung eingeführten Rohres, durch welches das Wärmetauschermedium in den Wärmetauscher eingeleitet oder aus ihm abgeleitet werden kann. Somit ergibt sich durch den Deckel keine Querschnittsveränderung des Strömungsquerschnitts des Wärmetauschermediums.The smallest diameter of the opening preferably corresponds to the inner diameter a pipe inserted into the opening, through which the Heat exchanger medium introduced into the heat exchanger or derived from it can be. Thus, no change in cross section results through the lid the flow cross-section of the heat exchanger medium.

This allows a large area for the introduction of Pipes between the two headers, making the headers small can be kept. In terms of the lid, this provides appropriate Design of the lid sure that the lid is not opposite The collection box can be rotated so that a positionally accurate Installation is possible without further measures.

Bevorzugt weist der Deckel eine Befestigungsöffnung auf, welche insbesondere durch eine Montageöffnung zur Befestigung des in die Öffnung eingeführten Rohres bildet, durch welches das Wärmetauschermedium in den Wärmetauscher eingeleitet oder aus ihm abgeleitet werden kann.Preferably, the lid has a mounting opening, which in particular through a mounting opening for fixing the inserted into the opening Pipe forms, through which the heat exchange medium in the Heat exchanger can be initiated or derived from it.

Das Rohr muss hierbei nicht notwendigerweise kreisförmig ausgebildet sein, sondem kann einen beliebigen anderen Querschnitt aufweisen, jedoch ist aus herstellungstechnischen Gründen die Kreisform bevorzugt.The tube does not necessarily have to be circular in this case, but it may have any other cross-section, but is For manufacturing reasons, the circular shape is preferred.

Ein derartiger Wärmetauscher wird insbesondere als Kondensator für eine Kraftfahrzeug-Klimaanlage verwendet.Such a heat exchanger is used in particular as a condenser for a Automotive air conditioning used.
