Abstract
Description
Die Erfindung betrifft einen Wärmeaustauscher mit einem gelöteten Kühlnetz aus
Flachrohren und Wärmeaustauschelementen, wobei die Enden der Flachrohre mit
in gegenüberliegenden Rohrböden angeordneten Öffnungen kommunizieren, so
dass ein wärmeaustauschendes Mittel durch die Flachrohre und die Öffnungen
strömen kann und mit Sammelkästen, deren Rand mit dem umlaufenden Rand der
Rohrböden mechanisch verbunden ist sowie mit den Rohrböden zugeordneten
Zwischenböden, die Ausschnitte aufweisen.
Ein solcher Wärmeaustauscher ist aus der US 4 903 389 bekannt. Mit dem bekannten
Wärmeaustauscher wird in vorteilhafter Weise eine verbesserte Flexibilität
des Designs erreicht, weil lediglich die dort vorgesehenen plattenartigen Zwischenböden
ersetzt werden müssen, um einen Wärmeaustauscher mit einem veränderten
Durchströmungsweg bzw. mit unterschiedlicher Wärmetauschleistung
bereitzustellen. Dieser Wärmeaustauscher ist ein Kondensator, dessen Durchströmmuster
des Kältemittels einen zick - zack - förmigen Weg aufweist.
Weitere Wärmeaustauscher sind aus dem EP 479 012 B1 bekannt. Die in dem EP
vorgesehenen Zwischenböden haben die Aufgabe, das durch Innendruck verursachte
Aufblähen der Flachrohre zu unterdrücken bzw. zu vermeiden.The invention relates to a heat exchanger with a soldered cooling network of flat tubes and heat exchange elements, the ends of the flat tubes communicating with openings arranged in opposite tube sheets, so that a heat-exchanging agent can flow through the flat tubes and the openings and with collecting boxes, the edge of which is connected to the peripheral edge the tube sheets are mechanically connected and to the tube sheets assigned to the tube sheets, which have cutouts.
Such a heat exchanger is known from US 4,903,389. With the known heat exchanger, improved design flexibility is advantageously achieved, because only the plate-like intermediate floors provided there have to be replaced in order to provide a heat exchanger with a changed flow path or with different heat exchange performance. This heat exchanger is a condenser whose flow pattern of the refrigerant has a zigzag path.
Further heat exchangers are known from EP 479 012 B1. The intermediate floors provided in the EP have the task of suppressing or avoiding the inflation of the flat tubes caused by internal pressure.
Wärmeaustauscher der angesprochenen Art erfordern zu ihrer Herstellung einen beträchtlichen Kostenaufwand, sogenannte Vorleistungen, worunter Werkzeuge, Vorrichtungen usw. zu verstehen sind, die für die Großserienfertigung notwendig sind. Es ist leicht nachvollziehbar, dass die Kosten pro Wärmeaustauscher umso mehr steigen, je geringer die zu produzierende Stückzahl ist. Insbesondere bei Wärmeaustauschern für Kraftfahrzeuge sind dieselben oftmals für unterschiedliche Kühlleistungen auszulegen, weil der Kunde Kraftfahrzeuge der gleichen Baureihe mit verschiedenen Motorleistungen nachfragt. Ein oftmals anzutreffendes Merkmal bei Wärmeaustauschern etwa gleichen Bauraums, jedoch unterschiedlicher Kühlleistung besteht darin, deren Kühlnetz mit unterschiedlicher Tiefe auszulegen, d. h. Flachrohre zu verwenden, deren großer Durchmesser für eine höhere Kühlleistung größer ist, bzw. umgekehrt, für geringere Kühlleistung kleiner ist. Diese Maßnahme zieht jedoch an und für sich wesentliche Kostenaufwände für neue Werkzeuge und Vorrichtungen nach sich, denn auf jeden Fall sind neue Rohrböden und gegebenenfalls auch neue Sammelkästen notwendig, die neue Werkzeuge erfordern.Heat exchangers of the type mentioned require one to manufacture them considerable expense, so-called advance payments, including tools, Devices etc. are to be understood, which are necessary for the mass production are. It is easy to understand that the costs per heat exchanger all the more increase the lower the number of pieces to be produced. Especially at Heat exchangers for automobiles are often the same for different ones To design cooling capacities because the customer has motor vehicles of the same series with different engine outputs. A common feature with heat exchangers of approximately the same installation space, but with different cooling capacities consists of designing their cooling network with different depths, d. H. To use flat tubes, their large diameter for a higher cooling capacity is larger, or vice versa, is smaller for lower cooling capacity. This measure however, attracts substantial costs for new tools and Devices themselves, because in any case there are new tube sheets and possibly new collection boxes are also required, which require new tools.
Die Aufgabe der vorliegenden Erfindung besteht darin, Wärmeaustauscher für höhere Kühlleistungen mit einem Kühlnetz größerer Tiefe mit geringem Änderungsaufwand zur Verfügung zu stellen.The object of the present invention is to provide heat exchangers for higher ones Cooling capacities with a cooling network of greater depth with little change effort to provide.
Erfindungsgemäß wird diese Aufgabe durch die Merkmale im Patentanspruch 1
gelöst. Weil die Zwischenböden einen Rand aufweisen, der mit dem umlaufenden
Rand der Rohrböden metallisch verbunden ist und weil die Zwischenböden eine
oder mehrere Öffnungen besitzen, so, dass zwischen dem Zwischenboden und
dem zugeordneten Rohrboden ein mit dem durch die Flachrohre strömenden wärmeaustauschenden
Mittel durchströmter Raum vorhanden ist, ist es möglich, mit
geringem Änderungsaufwand einen Wärmeaustauscher zur Verfügung zu stellen,
dessen Kühlleistung größer ist bzw. der eine größere Tiefe des Kühlnetzes aufweist.
Der erwähnte durchströmbare Raum sorgt für den Ausgleich der Tiefendifferenz.
Ferner dient der durchströmbare Raum dem Ausgleich von Druckunterschieden
über die Länge der Sammelkästen.
Der Zwischenboden kann lediglich eine oder wenige mit Versteifungsstegen versehene
Ausschnitte aufweisen. Dies ist dann der Fall, wenn der Zwischenboden
oberhalb des zugeordneten Rohrbodens angeordnet ist. Bevorzugt besitzt der Zwischenboden
jedoch den Flachrohrenden entsprechende Ausschnitte mit Durchzügen,
um die Flachrohrenden in den Durchzügen verlöten zu können. In diesen bevorzugten
Fällen ist der Zwischenboden unterhalb des zugeordneten Rohrbodens
angeordnet.
Die Sammelkästen des Wärmetauschers mit der geringeren Kühlleistung können
verwendet werden, ohne irgendwelche Änderungen vornehmen zu müssen. Außerdem
kann das Umformwerkzeug zur Herstellung der Rohrböden weiterhin benutzt
werden, wobei keine oder - bei bestimmten unten erläuterten Varianten - nur
geringfügige Änderungen daran notwendig sind. Im Prinzip besteht der einzige zusätzliche
Aufwand in der Bereitstellung eines Werkzeugs für die Zwischenböden,
wobei die Anforderungen an die Genauigkeit der Zwischenböden vergleichsweise
gering sind, weshalb der erforderliche Werkzeugaufwand niedrig ist. Auf jeden Fall
ist der Umformgrad der Zwischenböden geringer als derjenige der Rohrböden, was
ebenfalls zu relativ niedrigen Werkzeugkosten beiträgt. Somit macht es die Erfindung
möglich, die Werkzeuge und Vorrichtungen für die Großserie auszulegen. Da
in einer Fahrzeugbaureihe die Fahrzeuge mit etwas niedrigerer Motorleistung und
Kühlungsbedarf oftmals diejenigen sind, die in größeren Stückzahlen produziert
werden, können die Werkzeuge auf die dafür erforderlichen Bauteile zugeschnitten
werden. Beispielsweise weist ein darauf zugeschnittener Wärmeaustauscher eine
Kühlnetztiefe von etwa 30mm auf, was etwa dem großen Durchmesser der Flachrohre
des Kühlnetzes entspricht. In geringerer Stückzahl werden für Kraftfahrzeuge
der gleichen Baureihe aber mit größerer Motorleistung leistungsstärkere Wärmeaustauscher
benötigt, die eine Kühlnetztiefe von beispielsweise etwa 40 mm
aufweisen müssen. Dies geschieht dadurch, dass ein Zwischenboden hergestellt
und in den Wärmeaustauscher eingefügt wird, der, wie in den Ansprüchen 2 bis 5
näher gekennzeichnet wurde, ausgebildet ist und der auch aus der Beschreibung
der nachfolgenden Ausführungsbeispiele hervorgeht, wozu auf die beiliegenden
Figuren Bezug genommen wird.
Um nun mit sehr geringem Änderungsaufwand Flachrohre 2 mit größerem "großen" Durchmesser D (neu) zu verwenden oder, m. a. W., um den Wärmeaustauscher mit einem tieferen, leistungsstärkeren Kühlnetz auszustatten, ohne auf den, ebenfalls mit einem aufwendigen Werkzeug hergestellten,

Im Ausführungsbeispiel, das in den Fig. 5, 8 und 9 gezeigt ist, wurde in dem Folgewerkzeug zur Herstellung des
Ein wesentlicher weiterer Vorteil sämtlicher Varianten besteht darin, dass die äußere Kontur des
The intermediate floor can have only one or a few cutouts provided with stiffening webs. This is the case if the intermediate floor is arranged above the associated tube sheet. However, the intermediate floor preferably has cutouts with passages corresponding to the flat tube ends in order to be able to solder the flat tube ends in the passages. In these preferred cases, the intermediate floor is arranged below the associated tube sheet.
The header boxes of the heat exchanger with the lower cooling capacity can be used without having to make any changes. In addition, the forming tool can continue to be used to produce the tube sheets, with no or - in the case of certain variants explained below - only minor changes being necessary. In principle, the only additional effort is to provide a tool for the intermediate floors, the requirements for the accuracy of the intermediate floors being comparatively low, which is why the required tool effort is low. In any case, the degree of deformation of the intermediate floors is lower than that of the tube sheets, which also contributes to relatively low tool costs. The invention thus makes it possible to design the tools and devices for the large series. Since in a vehicle series the vehicles with somewhat lower engine output and cooling requirements are often the ones that are produced in larger quantities, the tools can be tailored to the components required for this. For example, a heat exchanger tailored to this has a cooling network depth of approximately 30 mm, which corresponds approximately to the large diameter of the flat tubes of the cooling network. In smaller numbers, more powerful heat exchangers are required for motor vehicles of the same series but with a greater engine output, which must have a cooling network depth of, for example, approximately 40 mm. This takes place in that an intermediate base is produced and inserted into the heat exchanger which, as was characterized in more detail in
In order to use
