Abstract
Description
Die Erfindung betrifft einen Wärmetauscher, insbesondere einen Kältemittelverdampfer, mit einem gelöteten Block aus paarweise eine U-förmige Führung und Sammelkanäle für ein Wärmetauschmittel bildenden, geprägten Platten, mit zwischen den Plattenpaaren angeordneten Wellrippen und mit an den Stirnenden des Blockes unter Zwischenfügen von Wellrippen angeordneten, plattenförmigen Seitenteilen.The invention relates to a heat exchanger, in particular a refrigerant evaporator, with a soldered block consisting of pairs of a U-shaped guide and collecting channels for an embossed plates forming a heat exchange medium, with corrugated fins arranged between the pairs of plates and with corrugated fins arranged on the end faces of the block with intermediate corrugated fins. plate-shaped side parts.
Bei derartigen Wärmetauschern müssen zusätzlich Anschlüsse für eine Zuleitung und eine Ableitung für Kältemittel vorgesehen werden. Hierzu ist es bekannt (US-PS 5 137 082), zwischen einer zum Sammelkanal gehörenden Prägung der letzten Platte und einem Seitenteil ein abgeflachtes Rohrstück einzusetzen.In such heat exchangers, additional connections for a supply line and a discharge line for refrigerant must be provided. For this purpose, it is known (US Pat. No. 5,137,082) to use a flattened piece of pipe between an embossing of the last plate belonging to the collecting duct and a side part.
Es ist auch bekannt (US-PS 5 125 453), zwischen zwei Plattenpaare besondere Anschlußelemente einzufügen, die ebenfalls plattenförmig gestaltet sind.It is also known (US Pat. No. 5,125,453) to insert special connecting elements between two pairs of plates, which are also plate-shaped.
Des weiteren ist es bekannt (US-PS 5 176 206), zwei der Plattenpaare mit einer besonderen Prägeform im Bereich der Sammelkanäle zu versehen, die zusammen jeweils einen Anschluß bilden.Furthermore, it is known (US Pat. No. 5,176,206) to provide two of the plate pairs with a special embossing shape in the region of the collecting channels, which together form a connection.
Der Erfindung liegt die Aufgabe zugrunde, einen Wärmetauscher der eingangs genannten Art fertigungstechnisch zu verbessern.The invention has for its object to improve a heat exchanger of the type mentioned in manufacturing.
Diese Aufgabe wird dadurch gelöst, daß die Seitenteile im Bereich der Sammelkanäle mit einer geprägten Profilierung versehen sind, die mit einem die letzte Platte verschließenden Abdeckblech eine Kammer bildet, die eine Verbindung zu wenigstens einem der Sammelkanäle aufweist.This object is achieved in that the side parts in the region of the collecting channels are provided with an embossed profiling which, with a cover plate closing the last plate, forms a chamber which has a connection to at least one of the collecting channels.
Eine derartige Kammer läßt sich in einfacher Weise in die Seitenteile integrieren, ohne daß dadurch zusätzliche Bauteile erforderlich werden. Nach wie vor kann das Seitenteil in der bekannten Weise vor dem Löten mit den Platten und den Wellrippen zu einem Block zusammengefügt werden, der dann als Ganzes in einem Ofen verlötet wird. Die auf diese Weise gebildete Kammer kann beispielsweise als eine Umlenkung zwischen zwei oder mehreren Sammelkanälen eingesetzt werden. Darüber hinaus ist es möglich, die Profilierung mit einer Aufnahmeöffnung für ein Anschlußstück zu versehen, so daß Anschlüsse für eine Zu- oder Ableitung ohne die Verwendung zusätzlicher Bauteile geschaffen werden, d.h. in ein oder beide Seitenteile integriert werden.Such a chamber can be easily integrated into the side parts without the need for additional components. As before, the side part can be assembled in a known manner before the soldering with the plates and the corrugated fins to form a block, which is then soldered as a whole in an oven. The chamber formed in this way can be used, for example, as a deflection between two or more collecting channels. In addition, it is possible to provide the profiling with a receiving opening for a connecting piece, so that connections for supply or discharge are created without the use of additional components, i.e. can be integrated into one or both side parts.

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 plurality of embossed plates (10, 11). These successive plates (10, 11), which each follow one another in mirror image, are also connected to one another in succession. The plates (10, 11), which are embossed from sheets, in particular sheets made of an aluminum alloy, are designed in a known manner such that a pair of plates (10, 11) forms a U-shaped guide for a refrigerant, whereby the legs of the U-shaped guide end in collecting channels. The plate (10) shown in dashed lines forms with the preceding plate (not shown) corresponding to the plate (11) between circumferential, adjacent edges, this U-shaped guide, for which purpose the plates are embossed in a manner not shown but known from the prior art are provided, which have only a relatively small depth. The plates (10, 11) are provided in the area of their upper ends with deeper embossments (12, 13, 14, 15) which have a greater embossing depth and which lie against one another with their outer surfaces. These embossments (12 to 15) have through holes, so that these embossments (12 to 15) form collecting channels for the heat exchange medium with the aid of the through holes. Corrugated ribs (16) are arranged between the plates (10, 11) and are likewise formed from a sheet, preferably made of an aluminum alloy. In this respect, the heat exchanger corresponds to the design known from the prior art, so that reference can be made to the prior art for further details.
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 covered with a flat cover plate (17). This cover plate (17) closes the embossments (13, 14) surrounded by flat surfaces. The cover plate (17) is followed by a side part (18), which is also 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 is supported on the cover plate (17) with a lower flange (19) and an upper flange (20). A corrugated fin (26) is arranged in the area between the flanges (19, 20) and connects the cover plate (17) to the side part (18). 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 embossments (12 to 15), the side part is provided with an embossed profile (21). The embossed profile (21) is surrounded on three sides with an edge, namely with the flange (20) and the edges (22, 23) with which it rests on the cover plate (17). On the remaining end face, the embossed profile (21) is open and thus forms with the cover plate (17) a connection opening (24) for a connection piece of an inlet or outlet. The chamber formed by the embossing (21) and the cover plate (17) with the connection opening (24) communicates with the collecting duct formed by the embossments (12, 13) via an opening (25) in the cover plate (17). This chamber can thus be used in a simple manner as a connection for this collecting duct.
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 von 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 provided in a corresponding manner on the then last plate (10) with a cover plate and a side part, which also has a profile corresponding to the profile (21), while the cover plate is then provided with an opening which corresponds to that of the embossing (14, 15) formed collection channel connects to this chamber. If in the chamber between the cover plate (17) and the side part (18) partition walls are installed, other flow profiles can 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 design 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) of the corrugated rib (26) mounted block is integrated, which is held in this way with a suitable clamping device. The block thus formed is then soldered in an oven. For this purpose, it is expediently provided that the plates (10, 11), the cover plate (17) and the side part (18) and the opposite elements are solder-plated, and, if appropriate, also the corrugated ribs (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 from the side part (18) only in the cross-sectional shape of the embossed profile (31), which has a semi-cylindrical shape. This profile (31) also extends on one side to the edge of the side part, while it is closed on the other side.
Bei einer gegenüber Fig. 1 und 2 abgewandelten Ausführungsform wird vorgesehen, daß die Prägung (21, 31) der Seitenteile (18, 28) zu beiden Rindern 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 an embodiment modified from FIGS. 1 and 2, it is provided that the embossing (21, 31) of the side parts (18, 28) is open to both cattle of the side part (18, 28). In this case, the "embossed" profile (21, 31) can also be achieved by appropriate folding or folding of the side part. Such profiling can accommodate connectors on both sides, ie form connection openings for connectors. In this case, a partition dividing the profile transversely is provided. This partition can be designed as an insert or as a non-deformed 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 design has the advantage that identical side parts (18) or (28) can be used for both ends of the heat exchanger, even if the inlet and outlet are 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) is provided with an embossed, cup-shaped profile (41) which is surrounded by peripheral edges. In this exemplary embodiment, a connection opening (34) is provided in one or both end walls of this embossed profiling (41) for a connecting piece of an inlet or outlet. Since this connection opening (34) is formed exclusively by the profiling (41), its shape can largely be chosen without regard to 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 according to FIG. 4, the side part is provided with an embossed profiling (51) which is closed on all sides and which forms a chamber closed to the outside with a cover plate (17), not shown. If openings are then provided in the cover plate corresponding to the collecting channels, this profile can be used as a deflection guide for the refrigerant.
