Der in Fig. 1 nur teilweise dargestellte Wärmetauscher, insbesondere ein sogenannter Plattenverdampfer für eine Klimaanlage eines Kraftfahrzeuges, besitzt eine Vielzahl von geprägten Platten (10, 11). Diese aufeinanderfolgenden Platten (10, 11), die jeweils spiegelbildlich aufeinanderfolgen, sind auch aufeinanderfolgend miteinander verbunden. Die Platten (10, 11), die aus Blechen, insbesondere Blechen aus einer Aluminiumlegierung, geprägt sind, sind in bekannter Weise derart gestaltet, daß jeweils ein Paar von Platten (10, 11) eine U-förmige Führung für ein Kältemittel bildet,wobei die Schenkel der U-förmigen Führung in Sammelkanälen enden. Die gestrichelt dargestellte Platte (10) bildet mit der nicht dargestellten, vorausgehenden Platte entsprechend der Platte (11) zwischen umlaufenden, aneinanderliegenden Rändern diese U-förmige Führung, wozu die Platten in nicht näher dargestellter, jedoch durch den Stand der Technik bekannter Weise mit Prägungen versehen sind, die nur eine relativ geringe Tiefe besitzen. Die Platten (10, 11) sind im Bereich ihrer oberen Enden mit tieferen Ausprägungen (12, 13, 14, 15) versehen, die eine größere Prägetiefe aufweisen und die mit ihren Außenflächen aneinanderliegen. Diese Prägungen (12 bis 15) besitzen Durchgangslöcher, so daß diese Prägungen (12 bis 15) mit Hilfe der Durchgangslöcher Sammelkanäle für das Wärmetauschmittel bilden. Zwischen den Platten (10, 11) sind Wellrippen (16) angeordnet, die ebenfalls aus einem vorzugsweise einer Aluminiumlegierung bestehenden Blech gebildet werden. Insoweit entspricht der Wärmetauscher der durch den Stand der Technik bekannten Bauweise, so daß bezüglich weiterer Einzelheiten auf den Stand der Technik verwiesen werden kann. The heat exchanger shown only partially in FIG. 1, in particular a so-called plate evaporator for an air conditioning system of a motor vehicle, has a variety of embossed Plates (10, 11). These successive plates (10, 11), which follow each other in mirror image are also successive connected with each other. The plates (10, 11), those made of sheets, especially sheets made of an aluminum alloy, are shaped, are designed in a known manner such that a pair of plates (10, 11) each have a U-shaped guide forms for a refrigerant, the legs of the U-shaped Leadership ends in collective channels. The one shown in dashed lines Plate (10) forms with the preceding, not shown Plate corresponding to the plate (11) between rotating, adjacent edges of this U-shaped guide, which is why Plates in a not shown, but by the stand known in the art are provided with embossings that have only a relatively shallow depth. The plates (10, 11) are in the area of their upper ends with deeper expressions (12, 13, 14, 15), which have a greater embossing depth and which lie together with their outer surfaces. These imprints (12 to 15) have through holes, so that these embossments (12 to 15) with the help of the through holes collecting channels form for the heat exchange medium. Between the plates (10, 11) are arranged corrugated ribs (16), which are also preferably made of a an aluminum alloy sheet formed become. In this respect, the heat exchanger corresponds to that of the State of the art construction, so that with respect to other Details can be referred to the prior art.
Die am äußeren Stirnende befindliche Platte (11) ist mit einem ebenen Abdeckblech (17) abgedeckt. Dieses Abdeckblech (17) verschließt die von ebenen Flächen umgebenen Prägungen (13, 14). Auf das Abdeckblech (17) folgt ein Seitenteil (18), das ebenfalls aus einem Blech einer Aluminiumlegierung gebildet ist. Das Seitenteil (18) besitzt eine im wesentlichen U-förmige Form und entspricht in seiner Breite der Breite der Platten (10, 11) und des Abdeckbleches (17). Es stützt sich mit einem unteren Flansch (19) und einem oberen Flansch (20) auf dem Abdeckblech (17) ab. In dem Bereich zwischen den Flanschen (19, 20) ist eine Wellrippe (26) angeordnet, die das Abdeckblech (17) mit dem Seitenteil (18) verbindet. Der untere Flansch (19) kann entfallen, da die Abstützung mittels der Wellrippe (26) ausreicht.The plate (11) located at the outer end is with a flat cover plate (17) covered. This cover plate (17) closes the embossments (13, 14) surrounded by flat surfaces. On the cover plate (17) is followed by a side part (18), which also is formed from a sheet of an aluminum alloy. The side part (18) has a substantially U-shaped shape and corresponds in width to the width of the plates (10, 11) and the cover plate (17). It relies on a lower one Flange (19) and an upper flange (20) on the cover plate (17). There is one in the area between the flanges (19, 20) Corrugated fin (26) arranged, the cover plate (17) with the Side part (18) connects. The lower flange (19) can be omitted, since the support by means of the corrugated fin (26) is sufficient.
In dem Bereich der Sammelkanäle, d.h. der Prägungen (12 bis 15), ist das Seitenteil mit einen geprägten Profil (21) versehen. Das geprägte Profil (21) ist an drei Seiten mit einem Rand umgeben, nämlich mit dem Flansch (20) und den Rändern (22, 23), mit denen es an dem Abdeckblech (17) anliegt. Auf der verbleibenden Stirnseite ist das geprägte Profil (21) offen und bildet somit mit dem Abdeckblech (17) eine Anschlußöffnung (24) für ein Anschlußstück einer Zu- oder Ableitung. Die von der Prägung (21) und dem Abdeckblech (17) gebildete Kammer mit der Anschlußöffnung (24) steht mit dem von den Prägungen (12, 13) gebildeten Sammelkanal über eine Öffnung (25) des Abdeckbleches (17) in Verbindung. Diese Kammer kann somit in einfacher Weise als Anschluß für diesen Sammelkanal ausgenutzt werden.In the area of the collecting channels, i.e. of the coins (12 to 15), the side part is provided with an embossed profile (21). The embossed profile (21) has an edge on three sides surrounded, namely with the flange (20) and the edges (22, 23), with which it rests on the cover plate (17). On the remaining one The embossed profile (21) is open on the front side and forms thus with the cover plate (17) a connection opening (24) for a connector of a supply or discharge. The embossing (21) and the cover plate (17) formed chamber with the connection opening (24) stands with that formed by the embossments (12, 13) Collecting channel through an opening (25) of the cover plate (17) in connection. This chamber can thus be easily can be used as a connection for this collecting channel.
Das gegenüberliegende Stirnende des Wärmetauschers ist in entsprechender Weise an der dann letzten Platte (10) mit einem Abdeckblech und einem Seitenteil versehen, das ebenfalls eine der Profilierung (21) entsprechende Profilierung aufweist, während das Abdeckblech dann mit einer Öffnung versehen ist, die den vcn den Prägungen (14, 15) gebildeten Sammelkanal mit dieser Kammer verbindet. Falls in die Kammer zwischen dem Abdeckblech (17) und dem Seitenteil (18) Trennwände eingebaut werden, können auch andere Strömungsverläufe vorgesehen werden.The opposite end of the heat exchanger is corresponding Way on the then last plate (10) with a cover plate and provided a side part, which is also one of the Profiling (21) has corresponding profiling, while the cover plate is then provided with an opening which vcn the embossing channel (14, 15) formed with this Chamber connects. If in the chamber between the cover plate (17) and the side part (18) partitions can be installed other flow profiles can also be provided.
Die Konstruktionsweise nach der Erfindung hat den Vorteil, daß ein Anschluß oder zumindest eine Anschlußöffnung (24) in den aus den Platten (10, 11), den Wellrippen (16), der Abdeckplatte (17) und dem Seitenteil (18) sowie der zwischen dem Abdeckblech (17) und dem Seitenteil (18) befindlichen Wellrippe (26) montierten Block integriert wird, der in dieser Weise mit einer geeigneten Spannvorrichtung gehalten wird. Der so gebildete Block wird dann in einem Ofen gelötet. Hierzu wird in zweckmäßiger Weise vorgesehen, daß die Platten (10, 11), das Abdeckblech (17) und das Seitenteil (18) sowie die gegenüberliegenden Elemente lotplattiert sind, sowie gegebenenfalls auch die Wellrippen (16, 26).The construction according to the invention has the advantage that a connection or at least one connection opening (24) in the from the plates (10, 11), the corrugated ribs (16), the cover plate (17) and the side part (18) and between the cover plate (17) and the side part (18) located corrugated fin (26) Block that is integrated in this way with a suitable clamping device is held. The educated one Block is then soldered in an oven. This will be more appropriate Way provided that the plates (10, 11), the cover plate (17) and the side part (18) and the opposite Elements are solder-plated, as well as the corrugated ribs if necessary (16, 26).
Das Seitenteil (28) der Ausführungsform nach Fig. 2 unterscheidet sich von dem Seitenteil (18) nur durch die Querschnittsform der geprägten Profilierung (31), die eine halbzylindrische Gestalt aufweist. Diese Profilierung (31) reicht ebenfalls auf einer Seite bis zu dem Rand des Seitenteils, während sie auf der anderen Seite geschlossen ist.The side part (28) of the embodiment according to FIG. 2 differs differ from the side part (18) only by the cross-sectional shape the embossed profile (31), which is a semi-cylindrical shape having. This profiling (31) is also sufficient one side to the edge of the side panel while on the other side is closed.
Bei einer gegenüber Fig. 1 und 2 abgewandelten Ausführungsform wird vorgesehen, daß die Prägung (21, 31) der Seitenteile (18, 28) zu beiden Rändern des Seitenteils (18, 28) hin offen ist. In diesem Fall läßt sich die "geprägte" Profilierung (21, 31) auch durch eine entsprechende Faltung oder Kantung des Seitenteils erzielen. Eine derartige Profilierung kann beidseits Anschlußstücke aufnehmen, d.h. Anschlußöffnungen für Anschlußstücke bilden. In diesem Fall wird eine die Profilierung quer unterteilende Trennwand vorgesehen. Diese Trennwand kann als ein Einsatz ausgeführt sein oder aber auch als ein nicht verformter Bereich zwischen den beiden geprägten Profilierungen. Darüber hinaus ist es auch möglich, eine der beiden Öffnungen mittels eines eingesetzten und eingelöteten Stopfens zu verschließen. Diese Ausbildung hat den Vorteil, daß identische Seitenteile (18) oder (28) für beide Stirnenden des Wärmetauschers verwendet werden können, auch wenn die Zu- und Ableitung auf der gleichen Seite angeschlossen werden soll.In a modified embodiment compared to FIGS. 1 and 2 it is provided that the embossing (21, 31) of the side parts (18, 28) is open to both edges of the side part (18, 28). In this case, the "embossed" profile (21, 31) also by appropriate folding or folding of the side part achieve. Such profiling can have connectors on both sides record, i.e. Connection openings for connecting pieces form. In this case, the profiling becomes transverse dividing partition provided. This partition can be used as an insert can be carried out or as an undeformed Area between the two embossed profiles. In addition, it is also possible to use one of the two openings to close with an inserted and soldered stopper. This training has the advantage that identical Side parts (18) or (28) for both ends of the heat exchanger can be used, even if the supply and discharge to be connected on the same side.
Bei dem Ausführungsbeispiel nach Fig. 3 ist das Seitenteil (38) mit einer geprägten, napfförmigen Profilierung (41) versehen, die von umlaufenden Rändern umgeben ist. Bei diesem Ausführungsbeispiel ist in einer oder beiden Stirnwänden dieser geprägten Profilierung (41) eine Anschlußöffnung (34) für ein Anschlußstück einer Zu- oder Ableitung vorgesehen. Da diese Anschlußöffnung (34) ausschließlich von der Profilierung (41) gebildet wird, kann ihre Form weitgehend beliebig gewählt werden, ohne Rücksicht auf das Abschlußblech (17).3, the side part (38) provided with an embossed, cup-shaped profile (41), which is surrounded by surrounding edges. In this embodiment is embossed in one or both end walls Profiling (41) a connection opening (34) for a connector a supply or discharge provided. Because this connection opening (34) formed exclusively by the profile (41) their shape can largely be chosen arbitrarily, regardless of the end plate (17).
Bei der Ausführungsform nach Fig.4 ist das Seitenteil mit einer allseitig geschlossenen geprägten Profilierung (51) versehen, die mit einem nicht dargestellten Abdeckblech (17) eine nach außen geschlossene Kammer bildet. Werden dann in dem Abdeckblech entsprechend den Sammelkanälen Öffnungen vorgesehen, so kann diese Proflierung als eine Umlenkführung für das Kältemittel ausgenutzt werden.In the embodiment of Figure 4, the side part with a embossed profiling (51) closed on all sides, the one with a cover plate (17), not shown outside closed chamber forms. Are then in the cover plate openings provided according to the collecting channels, so can this profile as a deflection guide for the refrigerant be exploited.
