Description
Die Erfindung bezieht sich auf einen Rohrblock-Wärmeübertrager
nach dem Oberbegriff des Anspruchs 1. Derartige Wärmeübertrager
werden beispielsweise in Flachrohrbauweise als
Öl/Luft-Kühler oder als Wasser/Luft-Kühler in Kraftfahrzeugen
verwendet. In diesem Anwendungsfall strömt die zu kühlende
Flüssigkeit von einem als Verteilerkanal fungierenden Anschlußkanal
auf einer Rohrblockquerseite durch die Rohre hindurch
zu einem als Sammelkanal fungierenden Anschlußkanal auf
der anderen Rohrblockauerseite und wird von zwischen den Rohren
hindurchgeblasener Luft gekühlt. Zur Verbesserung der
Wärmeübertragung ist meist eine Rippenstruktur in die Zwischenräume
zwischen den Rohren eingebracht.The invention relates to a tube block heat exchanger
according to the preamble of
Ein Rohrblock-Wärmeübertrager dieser Art ist beispielsweise in der Offenlegungsschrift EP 0 479 012 A1 beschrieben. Dort werden die Flachrohre mittels je eines Zwischenbodens oder Abstützkamms auf jeder Rohrblockquerseite auf Abstand gehalten. Die Rohre treten dabei durch Durchführungsöffnungen in den Zwischenböden bzw. den Abstützkämmen hindurch und münden endseitig offen in seitlich anschließende, kastenförmige, als Verteiler- bzw. Sammelkanal dienende Anschlußkanäle. A tube block heat exchanger of this type is for example in published patent application EP 0 479 012 A1. There are the flat tubes by means of an intermediate floor or Support comb is kept at a distance on each side of the pipe block.

Der Erfindung liegt als technisches Problem die Bereitstellung eines Rohrblock-Wärmeübertragers der eingangs genannten Art zugrunde, der vergleichsweise einfach herstellbar ist und wenigstens zwei voneinander getrennte Fluidkreisläufe besitzt.The invention is a technical problem of providing a tube block heat exchanger of the aforementioned Type based, which is comparatively easy to manufacture and has at least two separate fluid circuits.
Die Erfindung löst dieses Problem durch die Bereitstellung
eines Rohrblock-Wärmeübertragers mit den Merkmalen des Anspruchs
1. Dieser Wärmeübertrager besitzt einen vergleichsweise
einfach hergestellbaren Aufbau aus einzelnen, beabstandet
nebeneinanderliegenden und endseitig abgedichteten Rohren
sowie Distanzelementen, die zwischen je zwei benachbarten
Rohrendbereichen eingebracht sind, um die gewünschten Zwischenräume
zwischen den Rohren zu bilden. Die erforderlichen
Anschlußkanäle an den Rohrblockquerseiten sind durch jeweilige
Queröffnungen gebildet, die in den Endbereichen der Rohre
und in den Distanzelementen mit Ausnahme der Trennungs-Distanzelemente
vorgesehen sind. Durch das Anordnen eines
Paares von Trennungs-Distanzelementen, die keine derartigen
durchgehenden Queröffnungen besitzen und sich auf gleicher
Höhe im Rohrblock gegenüberliegen, werden auf jeder Rohrblockquerseite
in fertigungstechnisch einfacher Weise zwei
oder mehr voneinander getrennte Anschlußkanäle gebildet. Der
Rohrblock wird dadurch in aufeinanderfolgende Rohrblockabschnitte
unterteilt, die von mehreren Fluiden getrennt durch-strömt
werden können.The invention solves this problem by providing it

Dies realisiert mit geringem Herstellungsaufwand einen mit mehreren Fluiden jeweils voneinander separiert durchströmbaren Wärmeübertrager mit kompaktem Aufbau. Ein solcher Wärmeübertrager kann beispielsweise zur gleichzeitigen Kühlung von Motoröl einerseits und Getriebeöl andererseits mittels Luft in einem Kraftfahrzeug eingesetzt werden. Dabei ist lediglich ein einziger Kühlerblock im Fahrzeug zu befestigen, der ohne weiteres als Großflächenkühler ausgelegt sein kann. This is realized with a low manufacturing effort flow through several fluids separated from each other Heat exchanger with a compact structure. Such a heat exchanger can for example for the simultaneous cooling of Engine oil on the one hand and gear oil on the other hand by means of air be used in a motor vehicle. It is only to fix a single radiator block in the vehicle, which without can also be designed as a large area cooler.
In einer Weiterbildung der Erfindung nach Anspruch 2 sind U-förmige
Distanzschuhe vorgesehen, von denen jeder einen zugehörigen
Rohrendbereich umgreift, wobei benachbarte Distanzschuhe
kontaktierend aneinandergelegt und fest miteinander
verbunden sind. Auf diese Weise sind die Distanzelemente,
welche benachbarte Rohre auf Abstand halten, von je zwei miteinander
verbundenen Hälften zweier aufeinanderfolgender Distanzschuhe
gebildet. Die Trennungs-Distanzelemente sind dadurch
realisiert, daß zugehörige, sich auf gleicher Höhe gegenüberliegende
Distanzschuhhälften nicht mit einer durchgehenden
Queröffnung versehen sind. Diese Wärmeübertragerkonstruktion
erlaubt sehr flexibel die Einbringung der Trennungs-Distanzelemente
auf beliebiger, gewünschter Höhe des
Rohrblocks, so daß der Rohrblock sowohl in seiner Gesamtabmessung,
insbesondere der Anzahl der verwendeten Rohre, als
auch hinsichtlich seiner Aufteilung in die voneinander fluidgetrennten
Rohrblockabschnitte bei der Herstellung ohne größeren
Zusatzaufwand optimal auf den jeweiligen Anwendungsfall
abgestimmt werden kann.In a development of the invention according to
Bei einem nach Anspruch 3 weitergebildeten Wärmeübertrager
sind die Trennungs-Distanzelemente auf ihren freiliegenden
Außenseitenbereichen anders gestaltet als die übrigen Distanzelemente,
und zwar so, daß dies von einer entsprechenden
Sensorik erfaßt werden kann. Auf diese Weise ist am fertigen
Rohrblock-Wärmeübertrager rasch feststellbar, wo sich Trennungs-Distanzelemente

Der in Fig. 1 dargestellte Rohrblock-Wärmeübertrager beinhaltet einen Rohrblock aus mehreren, in einer Reihe in Rohrquerrichtung beabstandet nebeneinander angeordneten Flachrohren (1). In die Zwischenräume (2) zwischen den Flachrohren (1) sind in herkömmlicher Weise Wellrippen (3) angebracht, die in Fig. 1 der Übersichtlichkeit halber nur teilweise dargestellt sind. Die Wellrippen (3) dienen der verbesserten Wärmeübertragung zwischen Luft, die senkrecht zur Zeichenebene von Fig. 1 durch die Zwischenräume (2) hindurchgeblasen wird, und dem in den Flachrohren (1) strömenden Fluid.The tube block heat exchanger shown in Fig. 1 includes a pipe block of several, in a row in the pipe transverse direction spaced apart flat tubes (1). In the spaces (2) between the flat tubes (1) are attached in a conventional manner corrugated ribs (3) which in Fig. 1 only partially shown for clarity are. The corrugated fins (3) serve for improved heat transfer between air that is perpendicular to the plane of the drawing Fig. 1 is blown through the gaps (2), and the fluid flowing in the flat tubes (1).
Wie in Verbindung mit Fig. 2 genauer zu erkennen, ist jedes Flachrohr (1) an seinen beiden Stirnenden abgedichtet, z.B. mittels Anbringen eines Flachfalzes und gegebenenfalls zusätzlichem Dichtlöten. An beiden Endbereichen ist jedes Flachrohr (1) mit je einer durchgehenden Queröffnung (4a, 4b) versehen. Die Rohrendbereiche werden von je einem U-förmigen Distanzschuh (5) umgriffen. Zur Fertigung des Wärmeübertragers werden, wie in Fig. 2 durch die Pfeile angedeutet, zunächst auf jedes Flachrohr (1) die beiden Distanzschuhe (5) aufgesetzt und dann die so erhaltenen Distanzschuh-Flachrohr-Einheiten in einer Reihe aneinandergelegt, so daß sich benachbarte Distanzschuhe (5) berühren. Durch Löten oder ein anderes geeignetes Verbindungsverfahren werden dann die Distanzschuhe (5) über ihre sich berührenden Flächen fest miteinander verbunden, wobei jeder Distanzschuh (5) fest mit dem umgriffenen Rohrendbereich verbunden ist, so daß sich ein starrer Rohrblockaufbau ergibt. Dieser wird längsseitig durch je ein Abschlußplattenelement (6a, 6b) abgeschlossen, an denen Befestigungselemente (7a, 7b, 7c, 7d) vorgesehen sind, mit denen der Rohrblock-Wärmeübertrager am gewünschten Montageort angebracht werden kann.As can be seen more clearly in connection with FIG. 2, each is Flat tube (1) sealed at both ends, e.g. by attaching a flat fold and possibly additional Sealing soldering. Each is at both end ranges Flat tube (1), each with a continuous transverse opening (4a, 4b) Mistake. The tube end areas are each U-shaped Grasp the spacer shoe (5). To manufacture the heat exchanger are, as indicated by the arrows in Fig. 2, initially the two spacer shoes (5) on each flat tube (1) attached and then the spacer shoe flat tube units thus obtained put together in a row so that neighboring Touch spacer shoes (5). By soldering or a the spacer shoes are then another suitable connection method (5) firmly with each other via their touching surfaces connected, each spacer shoe (5) firmly with the encompassed pipe end area is connected, so that a rigid pipe block structure results. This is through along one end plate element (6a, 6b) each, at which Fastening elements (7a, 7b, 7c, 7d) are provided, with which the pipe block heat exchanger at the desired installation location can be attached.
Zur Bildung von Anschlußkanälen entlang der beiden Rohrguerseiten sind die Distanzschuhe (5) mit Ausnahme zweier spezieller Trennungs-Distanzschuhe (5a, 5b) auf jeder ihrer beiden Hälften mit je einer Queröffnung (8) versehen. Die Distanzschuh-Queröffnungen (8) fluchten beim fertiggestellten Rohrblockaufbau auf der jeweiligen Rohrquerseite untereinander und mit den zugehörgen Rohr-Queröffnungen (4a, 4b), wodurch ein jeweiliger, als Verteiler- oder Sammelkanal dienender Anschlußkanal gebildet ist. Um nun die getrennte Durchströmung des Rohrblockaufbaus mit zwei verschiedenen Fluiden zu ermöglichen, ist auf einer gewünschten Höhe des Rohrblocks anstelle der oben beschriebenen, normalen Distanzschuhe (5) ein spezielles Paar von Trennungs-Distanzschuhen (5a, 5b) vorgesehen, wie sie in Fig. 1 schraffiert markiert sind. Dies bedeutet, daß eines (1a) der Flachrohre mit diesen Trennungs-Distanzschuhen (5a, 5b) anstelle der normalen Distanzschuhe (5) versehen ist.For the formation of connection channels along the two sides of the pipe are the distance shoes (5) with the exception of two special ones Separation spacers (5a, 5b) on each of their two Halves each have a transverse opening (8). The spacer shoe cross openings (8) are aligned when the tube block assembly is completed one below the other on the respective transverse pipe side and with the associated pipe transverse openings (4a, 4b), whereby a respective connection channel serving as a distribution or collection channel is formed. Now about the separate flow to enable the pipe block assembly with two different fluids, is held at a desired height of the pipe block the normal spacer shoes (5) described above special pair of separation spacer shoes (5a, 5b) provided, as hatched in Fig. 1. This means, that one (1a) of the flat tubes with these separation spacers (5a, 5b) instead of the normal distance shoes (5) is provided.
Die Trennungs-Distanzschuhe (5a, 5b) unterscheiden sich von den übrigen Distanzschuhen (5) dadurch, daß sie nur auf einer (5c) ihrer beiden Hälften (5c, 5d) mit einer Queröffnung versehen sind, während die andere Hälfte (5d) geschlossen ausgebildet ist, wie dies für einen (5b) der beiden Trennungs-Distanzschuhe in der Detailansicht von Fig. 3 zu erkennen ist. Dabei liegen die beiden geschlossenen Hälften (5d) der beiden Trennungs-Distanzschuhe (5a, 5b) innerhalb desselben Zwischenraums (2a) zweier benachbarter Flachrohre. Damit wird in einfacher Weise eine Teilung der Anschlußkanalstruktur auf jeder Rohrguerseite in zwei getrennte Anschlußkanäle (9a, 9b) erreicht, wie sie in Fig. 3 für eine Rohrquerseite teilweise gezeigt sind. The separation spacer shoes (5a, 5b) differ from the remaining spacer shoes (5) in that they only on one (5c) of their two halves (5c, 5d) are provided with a transverse opening are formed while the other half (5d) is closed is like this for one (5b) of the two separation spacers can be seen in the detailed view of FIG. 3 is. The two closed halves (5d) lie here two separation spacer shoes (5a, 5b) within the same Gap (2a) between two adjacent flat tubes. So that will a division of the connection channel structure in a simple manner each pipe side in two separate connection channels (9a, 9b) achieved, as shown in Fig. 3 for a pipe transverse side are shown.
Mittels der beiden Trennungs-Distanzschuhe (5a, 5b) wird somit der Rohrblockaufbau in zwei Rohrblockabschnitte mit je einem Verteilerkanal auf der einen Rohrquerseite und einem zugehörigen Sammelkanal auf der anderen Rohrquerseite unterteilt, durch die zwei Fluide voneinander separiert hindurch-geführt werden können. Wie in Fig. 1 ersichtlich, sind für jeden der beiden Rohrabschnitte je ein nach außen führender Anschluß (10a, 10b; 11a, 11b) vorgesehen, von denen jeweils einer als Einlaß in den zugehörigen Verteilerkanal und der andere als Auslaß aus dem zugehörigen Sammelkanal fungieren. Beispielsweise kann der Wärmeübertrager von Fig. 1 als kombinierter Öl/Luft-Kühler zur gleichzeitigen Kühlung von Motoröl und Getriebeöl verwendet werden, indem durch den einen der beiden, durch die Trennungs-Distanzschuhe (5a, 5b) voneinander separierten Rohrblockabschnitte das zu kühlende Motoröl und durch den anderen Rohrblockabschnitt das zu kühlende Getriebeöl hindurchgeleitet werden und der gesamte Rohrblockaufbau mit Kühlluft angeströmt wird.By means of the two separation spacer shoes (5a, 5b) the pipe block structure in two pipe block sections each a distribution channel on one side of the pipe and one the associated collecting duct is divided on the other side of the pipe, passed through the two fluids separated from each other can be. As can be seen in Fig. 1, are for each of the two pipe sections, one leading to the outside Connection (10a, 10b; 11a, 11b) provided, each of which one as an inlet into the associated distribution channel and the others act as an outlet from the associated manifold. For example, the heat exchanger of FIG. 1 can be combined Oil / air cooler for simultaneous cooling of engine oil and transmission oil can be used by one of the both, by the separation spacers (5a, 5b) from each other separated pipe block sections the engine oil to be cooled and through the other pipe block section the gear oil to be cooled be passed through and the entire pipe block structure is blown with cooling air.
Wie aus Fig. 3 ersichtlich, bestimmen die Distanzschuhe (5, 5a, 5b) den Abstand benachbarter Flachrohre (1), der sich aus der doppelten Dicke einer Distanzschuhhälfte ergibt. Um die Trennungs-Distanzschuhe (5a, 5b) am fertigen Rohrblock leicht lokalisieren zu können, tragen sie eine spezielle, außenseitige Markierung (12), die an einer freibleibenden Stelle angeordnet ist und von einer entsprechenden Sensorik beispielsweise optisch erfaßt werden kann. Dabei kann die Markierung so gestaltet sein, daß an ihr ablesbar ist, welches die geschlossen ausgebildete Hälte (5d) des Trennungs-Distanzschuhs (5a, 5b) ist.3, the spacer shoes (5, 5a, 5b) the distance between adjacent flat tubes (1) that results from twice the thickness of a spacer half. To the Separation spacer shoes (5a, 5b) on the finished tube block easily to be able to localize, wear a special outside Marking (12) arranged in a non-binding place and from a corresponding sensor system, for example can be optically detected. The marking can be designed in such a way that you can see which one is closed trained halves (5d) of the separation spacer (5a, 5b).
Die Aufteilung des Rohrblockaufbaus in Zwei fluidgetrennte Rohrblockabschnitte kann auch durch alternative, erfindungsgemäße Gestaltungen erreicht werden. Beispielsweise können zwei sich auf den beiden Rohrquerseiten gegenüberliegende Trennungs-Distanzschuhe der oben beschriebenen Art vorgesehen sein, die gegeneinander in Rohrquerrichtung um einen Distanzschuh versetzt so angeordnet sind, daß ihre geschlossen ausgebildeten Hälften im gleichen Zwischenraum zwischen zwei benachbarten Flachrohren liegen.The division of the pipe block assembly into two fluid-separated Pipe block sections can also by alternative, inventive Designs can be achieved. For example two opposite each other on the two sides of the pipe Separation spacer shoes of the type described above are provided be against each other in the tube transverse direction around a spacer shoe are staggered so that their closed trained Halves in the same space between two neighboring ones Flat tubes lie.
Als weitere Alternative können anstelle der Distanzschuhe andersartige Distanzteile vorgesehen sein, welche die erforderlichen Distanzelemente zur gegenseitigen Beabstandung der Flachrohre bereitstellen. So könnten z.B. gelochte Plattenstücke als Distanzelemente zwischen die benachbarten Rohrendbereiche eingefügt und mit diesen dichtgelötet oder verklebt sein. Dabei ist dann je ein Paar von ungelochten Plattenstükken als Trennungs-Distanzelemente vorzusehen, welche die Funktion der Aufteilung des Rohrblocks in fluidgetrennte Abschnitte erfüllen.As a further alternative, different types can be used instead of the spacer shoes Spacers are provided, which the required Spacer elements for mutual spacing of the Provide flat tubes. For example, perforated plate pieces as spacer elements between the adjacent pipe end areas inserted and soldered or glued to them be. There is then a pair of non-perforated plate pieces to provide as separation spacers that the Function of dividing the pipe block into fluid-separated sections fulfill.
Selbstverständlich können je nach Bedarf auch mehrere Paare von Trennungs-Distanzelementen, welche die erläuterte Aufteilungsfunktion besitzen, vorgesehen werden, um den Rohrblock in mehr als zwei fluidgetrennte Abschnitte aufteilen und eine entsprechende Anzahl von Fluiden voneinander getrennt hindurchströmen lassen zu können. Für die nicht außenliegenden Rohrblockabschnitte ist dann jeweils seitlich ein geeigneter Ein- und Auslaß für den betreffenden Verteiler- bzw. Sammelkanal einzubringen.Of course, several pairs can be used as required of separation spacers, which the explained division function own, be provided around the pipe block divide into more than two fluid separated sections and one flow corresponding number of fluids separated from each other to be able to leave. For those not outside Pipe block sections are then laterally more suitable Inlet and outlet for the relevant distribution or collection channel bring in.
In einer weiteren Ausführungsform kann vorgesehen sein, daß die Rohre nicht wie beschrieben durch eine Falzung, sondern dadurch endseitig abgedichtet werden, daß die Distanzschuhe so auf die Flachrohre aufgesteckt werden, daß sie mit einer Hälfte in das Rohr eingreifen und mit diesem fluiddicht verbunden werden, z.B. durch Dichtlöten. Im fertiggestellten Rohrblockaufbau wechselt sich dann auf jeder Querseite jeweils eine Distanzschuhhälfte mit einer Flachrohrwandung sich berührend ab, wobei sie z.B. mittels Löten oder Kleben fest miteinander verbunden sind.In a further embodiment it can be provided that the pipes are not folded, as described, but be sealed at the end that the spacers be placed on the flat tubes in such a way that they Half engage in the pipe and connected to it in a fluid-tight manner e.g. by sealing soldering. In the finished Pipe block construction then changes on each transverse side a spacer shoe half with a flat tube wall itself touching, e.g. by means of soldering or gluing are interconnected.
