Ausgehend von diesem Stand der Technik, ist es Aufgabe der Erfindung, einen Sammler der eingangs genannten Art derart auszubilden, dass eine einfache Positionierung beider miteinander zu verlötender Blechteile möglich ist. Es ist ferner Aufgabe der Erfindung, einen Wärmeübertrager der eingangs genannten Art mit einem verbesserten Sammler auszustatten.outgoing From this prior art, it is an object of the invention to provide a Collector of the type mentioned in such a way that a simple Positioning of both to be soldered sheet metal parts is possible. It is a further object of the invention to provide a Heat exchanger of the type mentioned with to equip an improved collector.
Die Aufgabe der Erfindung wird durch die unabhängigen Ansprüche 1 und 14 gelöst. Vorteilhafte Ausgestaltungen ergeben sich aus den Unteransprüchen.The The object of the invention is achieved by the independent claims 1 and 14 solved. Advantageous embodiments arise from the dependent claims.
Erfindungsgemäß ist vorgesehen, dass die Lötflächen zwischen den Trennwänden in einer anderen Ebene als die umlaufenden Lötfalze angeordnet sind. Die Lötflächen zwischen den Trennwänden liegen also nicht in derselben Ebene, in welcher der umlaufende Lötfalz von Boden- und Deckelteil angeordnet ist. Durch den Versatz der Lötflächen gegenüber dem Lötfalz ergibt sich der Vorteil, dass sich beide Blechteile, die miteinander zu verlöten sind, zueinander positionieren. Damit entfällt ein zusätzlicher Arbeitsschritt, d. h. das Herstellungsverfahren, insbesondere die Vorbereitung der Teile für den anschließenden Lötprozess wird vereinfacht.According to the invention provided that the solder pads between the partitions arranged in a different plane than the circumferential Lötfalze are. The soldering surfaces between the partitions lie So not in the same plane in which the circumferential soldering fold is arranged by bottom and top part. By the offset of the Soldering surfaces opposite the soldering fold There is the advantage of getting both sheet metal parts together to be soldered, position each other. This is eliminated an additional step, d. H. the manufacturing process, in particular the preparation of the parts for the subsequent Soldering process is simplified.
Nach einer bevorzugten Ausführungsform ist vorgesehen, dass die Lötfalze in einer ersten Ebene und die Lötflächen der Trennwände im Wesentlichen in einer zweiten Ebene angeordnet sind, welche gegenüber der ersten Ebene parallel versetzt ist. Zwischen den versetzten Lötflächen und dem umlaufenden Lötfalz sind Übergänge verschiedener Art vorgesehen, beispielsweise durch eine kontinuierliche Schräge oder durch einen kurzen steilen Absatz. Für eine bessere Verlötung an den Übergängen zum Lötfalz können Ausrundungen oder Ausbuchtungen vorgesehen werden, wodurch eine verbesserte Dichtlötung erzielt wird.To A preferred embodiment provides that the Lötfalze in a first level and the soldering surfaces the partitions arranged substantially in a second plane are, which offset parallel to the first plane is. Between the offset pads and the circumferential soldering fold are transitions of different Art provided, for example, by a continuous slope or by a short steep paragraph. For a better one Soldering at the transitions to Lötfalz fillets or bulges may be provided whereby an improved Dichtlötung is achieved.
Nach einer weiteren bevorzugten Ausführungsform können die Lötflächen und der umlaufende Lötfalz V-förmig, d. h. in zwei geneigten, sich im Bereich der Längsmittelebene des Sammlers schneidenden Ebenen angeordnet sein. Eine Hälfte der Querwände bildet somit mit einem benachbarten Lötfalz eine erste Ebene, und die zweite Hälfte der Querwände bildet mit dem benachbarten Lötfalz eine zweite Ebene. Auch durch diese V-Form erfolgt eine Positionierung beider zu verlötender Blechteile.To Another preferred embodiment the soldering surfaces and the circumferential soldering fold V-shaped, d. H. in two inclined, in the field of Longitudinal plane of the collector arranged intersecting planes be. One half of the transverse walls thus forms with an adjacent solder joint a first level, and the second Half of the transverse walls forms with the adjacent one Lötfalz a second level. Also done by this V-shape a positioning of both to be soldered sheet metal parts.
Nach einer besonders bevorzugten Ausführungsform ist das Bodenteil als Rohrboden mit Durchzügen zur Aufnahme von Rohren bzw. Rohrenden ausgebildet. Dagegen ist das Deckelteil als Anschlussplatte mit Anschlussöffnungen für ein Strömungsmedium ausgebildet.To a particularly preferred embodiment is the bottom part as tubesheet with passages for receiving pipes or Pipe ends formed. In contrast, the cover part as a connection plate with connection openings for a flow medium educated.
Nach einer weiteren bevorzugten Ausführungsform kann das Deckelteil als Umlenkplatte ausgebildet sein, welche in Verbindung mit einem Rohrboden eine Umlenkung des Strömungsmediums in Tiefenrichtung, d. h. von einer Rohrreihe in die andere bewirkt.To In another preferred embodiment, the lid part be designed as a baffle, which in conjunction with a Tube bottom a deflection of the flow medium in the depth direction, d. H. from one row of pipes to the other.
Nach einer weiteren bevorzugten Ausführungsform ist der Wärmeübertrager als Verdampfer ausgebildet, d. h. der Sammler sowie die in ihn mündenden Rohre werden von einem Kältemittel eines Kältemittelkreislaufs durchströmt.To Another preferred embodiment is the heat exchanger designed as an evaporator, d. H. the collector as well as those opening up in it Pipes are supplied by a refrigerant of a refrigerant circuit flows through.
Nach einer besonders bevorzugten Ausführungsform sind die Lötflächen der Trennwände im Rohrboden gegenüber dessen umlaufenden Lötfalz abgesenkt, während gleichzeitig die Lötflächen der Trennwände in der Anschlussplatte gegenüber deren umlaufenden Lötfalz erhöht sind. Diese Variante bietet vor allem fertigungstechnische, insbesondere umformtechnische Vorteile bei der Umformung der Blechteile.According to a particularly preferred embodiment, the soldering surfaces of the partitions in the tubesheet are opposite to the circumferential soldering fold lowered, while at the same time the solder surfaces of the partitions are increased in the terminal plate relative to the peripheral Lötfalz. This variant offers especially manufacturing technology, in particular forming technical advantages in the transformation of the sheet metal parts.
