Description

Die Erfindung betrifft einen Wärmeübertrager, insbesondere einen Kühlmittelkühler nach dem Oberbegriff des Patentanspruches 1.The invention relates to a heat exchanger, in particular a coolant radiator according to the preamble of claim 1.

Es ist bekannt, Wärmeübertrager von Kraftfahrzeugen, z. B. Kühlmittelkühler, Kältemittelkondensatoren oder Ladeluftkühler luftseitig hintereinander anzuordnen, und zwar in einer vormontierten Baugruppe, die auch als Kühlmodul bezeichnet wird. Das Kühlmodul wird im Fahrzeug im vorderen Bereich des Motorraumes angeordnet, wo insbesondere, in Luftströmungsrichtung gesehen, relativ wenig Bauraum zur Verfügung steht. Die einzelnen Wärmeübertrager müssen daher so dicht wie möglich hintereinander angeordnet werden - dies ist jedoch - bedingt durch die unterschiedliche Bauart der einzelnen Wärmeübertrager nicht immer möglich. Beispielsweise ergibt sich bei mechanisch gefügten Wärmeübertragern wie Kühlmittelkühlern ein so genannter Überstand der Kühlmittelkästen gegenüber den Stirnseiten des Kühlerblockes, welcher aus Rohren und Rippen aufgebaut ist. Die Kühlmittelkästen haben somit in Luftströmungsrichtung gesehen eine größere Tiefe als der Block des Kühlmittelkühlers, weshalb der Abstand zum benachbarten Wärmeübertrager durch den Überstand des Kastens gegenüber der Stirnseite des Blockes bestimmt wird. Dieser Abstand erhöht somit die Bautiefe eines Kühlmoduls und ist aus thermodynamischen Gründen nicht erforderlich.It is known heat exchangers of motor vehicles, for. B. coolant radiator, refrigerant condensers or intercooler air side by side to arrange, in a preassembled module, which is also referred to as a cooling module. The cooling module is arranged in the vehicle in the front region of the engine compartment, where in particular, seen in the air flow direction, relatively little space is available. The individual heat exchangers must therefore be arranged as close as possible one behind the other - but this is not always possible - due to the different design of the individual heat exchanger. For example, results in mechanically joined heat exchangers such as coolant radiators, a so-called supernatant of the coolant boxes relative to the front sides of the radiator block, which is composed of pipes and ribs. The coolant boxes thus have a greater depth in the direction of air flow than the block of the coolant cooler, for which reason the distance to the adjacent heat exchanger is determined by the projection of the box relative to the face of the block. This distance thus increases the depth of a cooling module and is not necessary for thermodynamic reasons.

Mechanisch gefügte Wärmeübertrager, insbesondere Kühlmittelkühler wurden durch die DE 28 52 408 B2 , die DE 28 52 409 C2 oder die DE 38 41 470 A1 bekannt. Die bekannten Kühler weisen einen aus Rohren und Rippen bestehenden Block auf, der mechanisch gefügt oder gelötet sein kann. Die Rohre dieses Blockes münden jeweils in einen Sammel- oder Verteilerkasten, auch Kühlmittelkasten genannt, welcher aus einem metallischen Boden und einem Kunststoffdeckel unter Zwischenlage einer Dichtung zu einem dichten Behälter gefügt wird. Der Boden weist einen inneren Bereich auf, in welchem Durchzüge zur Aufnahme der Rohrenden angeordnet sind, welche durch mechanische Aufweitung oder eine Lötverbindung mit den Durchzügen verbunden sein können. Der äußere Bereich des Bodens weist eine umlaufende Rinne auf, in welche eine elastomere Dichtung eingelegt ist, welche den Boden gegenüber dem Deckel aus Kunststoff abdichtet. Die Verbindung zwischen Boden und Deckel ist beispielhaft in der DE 28 52 408 B2 dargestellt und wird als so genannte Wellenschiftzbördelung bezeichnet, weil im Bodenrand Schlitze angeordnet sind und der Bodenrand wellenförmig verformt wird. In der DE 38 41 470 A1 ist eine Weiterbildung der Wellenschlitzbördelung beschrieben, welche durch einen erhöhten Wasserkastenfuß mit oberen Werkzeugansatzflächen, so genannten Schlief3balkonen, gekennzeichnet ist. An diesen Flächen greifen beim Verbinden von Deckel und Boden Schließwerkzeuge, z. B. Stempel an und üben zur Erzeugung einer Vorspannung eine Druckkraft auf die Dichtung aus. Bei dieser Bauart mit metallischem Rohrboden und Kunststoffkasten ergibt sich ein Überstand des Kastens bzw. Rohrbodens gegenüber dem Block einerseits durch die Breite der Rinne und andererseits durch den Abstand der Rinne gegenüber dem Block bzw. den Rohren des Blockes, deren Enden in den. Durchzügen des Bodens stecken. Die Durchzüge müssen aus fertigungstechnischen Gründen einen minimalen Abstand zur Rinne aufweisen.Mechanically joined heat exchangers, in particular coolant radiators, were replaced by the DE 28 52 408 B2 , the DE 28 52 409 C2 or the DE 38 41 470 A1 known. The known coolers have a block consisting of tubes and ribs, which can be mechanically joined or soldered. The tubes of this block each open into a collection or distribution box, also called coolant box, which is joined from a metallic bottom and a plastic lid with the interposition of a seal to a sealed container. The bottom has an inner region in which passages for receiving the pipe ends are arranged, which can be connected by mechanical expansion or a solder joint with the passages. The outer region of the bottom has a circumferential groove, in which an elastomeric seal is inserted, which seals the bottom against the lid made of plastic. The connection between bottom and lid is exemplary in the DE 28 52 408 B2 and is referred to as a so-called Wellenschiftenzbördelung because slots are arranged in the bottom edge and the bottom edge is deformed wave-shaped. In the DE 38 41 470 A1 a development of the Wellenschlitzbördelung is described, which is characterized by a raised Wasserkastenfuß with upper tool attachment surfaces, so-called Schlief3balkonen. At these surfaces grip when connecting lid and bottom closing tools, eg. B. stamp and exert to generate a bias a compressive force on the seal. In this type with metallic tube sheet and plastic box results in a supernatant of the box or tube bottom relative to the block on the one hand by the width of the channel and the other by the distance of the channel relative to the block or the tubes of the block whose ends in the. Passing through the soil. The passages must have a minimum distance to the channel for manufacturing reasons.

Es ist Aufgabe der vorliegenden Erfindung, bei einem Wärmeübertrager der eingangs genannten Art den Bodenüberstand gegenüber dem Block auf ein minimales Maß zu reduzieren, um somit eine geringere Bautiefe des Wärmeübertragers in Luftsträmungsrichtung zu erreichen.It is an object of the present invention to reduce in a heat exchanger of the type mentioned in the bottom projection relative to the block to a minimum level, so as to achieve a smaller overall depth of the heat exchanger in Luftsträmungsrichtung.

Diese Aufgabe wird durch die Merkmale des Patentanspruches 1 gelöst. Der mit X bezeichnete Überstand setzt sich aus einer Reihe von Einzelmaßen zusammen, wobei mit x1 der Abstand der Rinne von der Stirnseite des Blockes bzw. der Rohre bezeichnet ist. x1 ist somit der Spalt zwischen der Stirnseite des Blockes und der Wand der Rinne. Erfindungsgemäß wird dieses Maß x1 auf einen Wert unter 0,5 mm reduziert, vorzugsweise gilt: 0,1 ≤ x1 ≤ 0,5 mm. Damit ist der Spalt zwischen dem Block und der Rinne auf ein Minimum reduziert, sodass ein Fügen der Rohre in den Boden bzw. dessen Durchzüge noch möglich ist. Damit ergibt sich ein erster wesentlicher Beitrag zur Reduzierung des Überstandes und zur Reduzierung der Bautiefe des Wärmeübertragers..This object is solved by the features of claim 1. The supernatant designated X is composed of a series of individual dimensions, where x1 is the distance of the channel from the front side of the block or the tubes is designated. x1 is thus the gap between the face of the block and the wall of the groove. According to the invention, this dimension x1 is reduced to a value of less than 0.5 mm, preferably: 0.1 ≦ x1 ≦ 0.5 mm. Thus, the gap between the block and the gutter is reduced to a minimum, so that a joining of the tubes in the ground or its passages is still possible. This results in a first significant contribution to reducing the supernatant and reducing the depth of the heat exchanger.

Nach einer besonderen Ausgestaltung der Erfindung ist die umlaufende Rinne zur Aufnahme der Dichtung von zwei Wänden, einer inneren mit der Wandstärke x2 und einer äußeren mit der Wandstärke x3, begrenzt. Die Wandstärke x3 der äußeren Wand entspricht der Wandstärke des Blechmaterials für den Boden, während die Wandstärke x2 der inneren Wand reduziert ist, d. h. x2 < x3. Durch die partielle Verdünnung der Bodenwandstärke im Bereich der inneren Rinnenwand ergibt sich eine weitere Reduzierung des Überstandes X. Vorzugsweise ist die Wandstärke x2. um 0,2 mm gegenüber der Wandstärke x3 auf der Außenseite reduziert. Diese Maßnahme trägt auch der Beanspruchung des Bodenmaterials in diesen beiden Bereichen Rechnung; Die Außenwand mit der Wandstärke x3 wird aufgrund der Bördelverbindung, z. B. eine Wellenschlitzbördelung gemäß dem eingangs genannten Stand der Technik erheblich stärker beansprucht, insofern ist hier eine größere Wandstärke erforderlich. Auf dem innen liegenden Bereich der Rinne treten geringere Beanspruchungen auf, sodass hier eine Reduzierung der Wandstärke zu Gunsten eines verringerten Überstandes möglich ist.According to a particular embodiment of the invention, the circumferential groove for receiving the seal of two walls, an inner with the wall thickness x2 and an outer with the wall thickness x3, limited. The wall thickness x3 of the outer wall corresponds to the wall thickness of the sheet material for the floor, while the wall thickness x2 of the inner wall is reduced, i. H. x2 <x3. The partial dilution of the bottom wall thickness in the region of the inner channel wall results in a further reduction of the projection X. Preferably, the wall thickness x2. reduced by 0.2 mm compared to the wall thickness x3 on the outside. This measure also takes into account the load on the soil material in these two areas; The outer wall with the wall thickness x3 is due to the flare, z. B. a Wellenschlitzbördelung according to the above-mentioned prior art significantly more stressed, insofar a larger wall thickness is required here. On the inside of the channel lower stresses occur, so here a reduction of the wall thickness in favor of a reduced supernatant is possible.

In das Gesamtmaß des Überstandes X geht auch ein weiteres Maß x4 ein, welches, die lichte Weite der umlaufenden Rinne betrifft. Gemäß einer bevorzugten Ausführung ist auch dieses Maß gegenüber dem Stand der Technik reduziert, was gleichzeitig eine Reduzierung des Dichtungsdurchmessers und der Breite des Deckelflansches, der von der Rinne aufgenommen wird, erforderlich macht.In the overall dimension of the supernatant X is also another measure x4, which, concerns the clear width of the circumferential groove. According to a preferred embodiment, this measure is also reduced compared to the prior art, which at the same time makes it necessary to reduce the sealing diameter and the width of the cover flange which is received by the groove.

In weiterer Ausgestaltung der Erfindung weist der Deckel (auch Kunststoffkasten oder Wasserkasten genannt) einen umlaufenden Flansch, auch Wasserkastenfuß genannt, auf, der mit Vorsprüngen, auch Schließbalkone genannt, versehen ist. Erfindungsgemäß sind diese Vorsprünge korrespondierend zur Rohrteilung, d. h. des Abstandes der Rohre zueinander angeordnet. Beispielsweise kommt auf zwei Rohre ein Vorsprung oder Schließbalkon, wobei vorzugsweise auf der Innenseite des Wasserkastens jeweils eine Aussparung für die beiden Rohre vorgesehen ist, wodurch der Fuß oder Flansch des Deckels insgesamt schmaler werden kann. Dadurch ist auch eine Reduzierung des vorgenannten Maßes x4 (lichte Weite der Rinne) möglich.In a further embodiment of the invention, the lid (also called plastic box or water tank) a circumferential flange, too Called Wasserkastenfuß, on, which is provided with projections, also called locking balconies, provided. According to the invention, these projections are corresponding to the pipe pitch, ie the distance of the tubes arranged to each other. For example, comes on two pipes a projection or locking balcony, preferably on the inside of the water box each having a recess for the two tubes is provided, whereby the foot or flange of the lid can be narrowed overall. As a result, a reduction of the aforementioned measure x4 (clear width of the channel) is possible.

Nach einer weiteren bevorzugten Ausführung der Erfindung sind im inneren Bodenbereich so genannte Einführsicken angeordnet, welche mit ihren Stirnseiten bis in den Bereich der umlaufenden Rinne auf den Längsseiten des Bodens reichen. Damit wird beim Einsetzen des Kunststoffkastens in die Rinne des Bodens eine Spreizung des Kastens erreicht, wenn dieser - bedingt durch den Spritzvorgang - längsseitig eingefallen ist, d. h. nicht die erforderliche lichte Weite, sondern eine geringere aufweist. Somit wird der Vorteil erreicht, dass die Kästen leichter in die umlaufende Rinne eingeführt werden können. Dafür ist es vorteilhaft, wenn die Einführsicken etwa in der Mitte der Böden und sich diametral gegenüberliegend angeordnet sind.According to a further preferred embodiment of the invention, so-called insertion beads are arranged in the inner bottom region, which extend with their end faces into the region of the circumferential groove on the longitudinal sides of the floor. Thus, a spread of the box is achieved when inserting the plastic box in the gutter of the bottom, if this - caused by the injection process - has fallen along the side, d. H. not the required clear width, but has a lower. Thus, the advantage is achieved that the boxes can be easily inserted into the circumferential groove. It is advantageous if the Einführsicken are arranged approximately in the middle of the floors and diametrically opposite.

Nach einer weiteren bevorzugten Ausführung der Erfindung ist der gesamte Überstand X kleiner als 8 mm, vorzugsweise gleich oder kleiner als 6 mm. Dabei setzt sich das Gesamtmaß X des Überstandes aus den Einzelmaßen x1, x2, x3, x4 zusammen, wobei - wie oben ausgeführt - x1 der Abstand der Rinne vom Block, x2 die Wandstärke der inneren Rinnenwand, x3 die Wandstärke der äußeren Rinnenwand und x4 die lichte Weite der Rinne ist. Erfindungsgemäß sind diese Maße - ohne Beeinträchtigung der Funktion der Verbindung zwischen Boden und Kasten - derart optimiert, sodass sich eine Reduzierung des Überstandes X gegenüber dem Stand der Technik von bis zu 3 mm ergibt. Der Überstand weist somit ein Maß X von ca. 6 mm auf. Damit ist es möglich, insbesondere bei der Anordnung der Wärmeübertrager in einem Kühlmodul einen geringeren Abstand zwischen den Stirnflächen benachbarter Wärmeübertrager zu realisieren und damit einen Gewinn an Bauraum zu erzielen.According to another preferred embodiment of the invention, the entire supernatant X is smaller than 8 mm, preferably equal to or smaller than 6 mm. The overall dimension X of the supernatant is composed of the individual dimensions x1, x2, x3, x4, wherein - as stated above - x1 the distance of the channel from the block, x2 the wall thickness of the inner channel wall, x3 the wall thickness of the outer channel wall and x4 the clear width of the gutter is. According to the invention, these dimensions - without affecting the function of the connection between the bottom and the box - optimized so that a reduction of the supernatant X compared to the prior art results in up to 3 mm. The supernatant thus has a dimension X of about 6 mm. This makes it possible, in particular in the arrangement of the heat exchanger in a cooling module to realize a smaller distance between the end faces of adjacent heat exchanger and thus to achieve a gain in space.

Der Boden 3, auch Rohrboden genannt, weist einen etwa rechteckförmigen Grundriss mit einer umlaufenden rinnenartigen Vertiefung, im Folgenden Rinne 4 genannt, auf, in welche eine Rundschnurdichtung 5 eingelegt ist, deren Durchmesser mit x6 bezeichnet ist. Die Rinne 4, welche einen U-förmigen Querschnitt aufweist, wird durch eine innere Wand 4a und eine äußere Wand 4b seitlich begrenzt. Der Deckel 2 weist einen umlaufenden verdickten Flansch 6, auch Fuß genannt, auf, welcher auf der Dichtung 5 aufliegt und in die Rinne 4 eingesetzt ist. Die Breite des Flansches 6 ist mit x5 gekennzeichnet. Der Boden 3 weist einen inneren, von der Rinne 4 begrenzten Bereich 3a auf, in welchen Durchzüge 7 eingeformt sind, die sich über die gesamte Breite des Bodenbereiches 3a erstrecken und Flachrohre 8 (nur angedeutet) aufnehmen. Fig. 1 shows a cross section through a coolant box 1 of a not fully shown coolant radiator, which is used for cooling an internal combustion engine of a motor vehicle. The coolant radiator 1 is preferably part of a cooling module, not shown, which can be installed in the front engine compartment of a motor vehicle, and is flowed through by ambient air. The coolant box 1 consists of a plastic lid 2, which has an approximately U-shaped cross-section and is mechanically connected to a metallic bottom 3. The bottom 3, also called tube plate, has an approximately rectangular floor plan with a circumferential groove-like depression, hereinafter called gutter 4, in which a round cord seal 5 is inserted, whose diameter is designated x6. The channel 4, which has a U-shaped cross-section, is bounded laterally by an inner wall 4a and an outer wall 4b. The cover 2 has a circumferential thickened flange 6, also called foot, which rests on the seal 5 and is inserted into the channel 4. The width of the flange 6 is marked x5. The bottom 3 has an inner, bounded by the channel 4 region 3a, in which passages 7 are formed, which extend over the entire width of the bottom portion 3a and flat tubes 8 (only hinted) record.

Die Flachrohre 8 bilden mit nicht dargestellten Wellrippen einen ebenfalls nicht dargestellten Block, auch Netz genannt, welcher sekundärseitig von Luft durchströmt wird. Die Tiefe des Blockes in Luftströmungsrichtung entspricht etwa der Tiefe des Flachrohres 8. Beim dargestellten Ausführungsbeispiel sind die Flachrohre 8 mit den Wellrippen und die Enden der Flachrohre 8 mit den Durchzügen 7 des Bodens 3 verlötet. Der Boden 3 weist in seinem inneren Bereich 3a ferner eingeformte Sicken 9 zur Versteifung auf. Der gesamte Boden 3 wird aus einem Blechmaterial, vorzugsweise einem Aluminiumblech durch spanlose Umformung hergestellt.The flat tubes 8 form with not shown corrugated fins also not shown block, also called network, which is traversed on the secondary side of air. The depth of the block in the air flow direction corresponds approximately to the depth of the flat tube 8. In the illustrated embodiment, the flat tubes 8 are soldered to the corrugated fins and the ends of the flat tubes 8 with the passages 7 of the bottom 3. The bottom 3 has in its inner region 3a also formed in beads 9 for stiffening. The entire bottom 3 is made of a sheet material, preferably an aluminum sheet by chipless forming.

Fig. 2 zeigt ein Segment des Deckels 2, der als Kunststoffspritzteil hergestellt wird. Auf der Außenseite des Deckels 2 und oberhalb des Flansches 6 sind Vorsprünge 10, so genannte Schließbalkone, angeordnet, an welchen nicht dargestellte Schließwerkzeuge bei der Verbindung von Boden 3 und Deckel 2 angreifen. Ein entsprechendes Schließverfahren ist in dem eingangs genannten Stand der Technik ( DE 38 41 470 A1 der Anmelderin),beschrieben. Abweichend gegenüber dem Stand der Technik sind auf der Innenseite des Deckels 2 Aussparungen 11 eingeformt, in welche die hier nicht dargestellten Flachrohre 8 mit ihren Schmalseiten eingreifen. Die Aussparungen 11 sind somit im Abstand der Rohrleitung angeordnet. Durch die Aussparungen 11 kann die Breite des Kühlmittelkastens 1 reduziert werden. Fig. 2 shows a segment of the lid 2, which is made as a plastic injection molded part. On the outside of the lid 2 and above the flange 6 are projections 10, so-called locking balconies, arranged on which locking tools, not shown, engage in the connection of the bottom 3 and cover 2. A corresponding closing method is in the above-mentioned prior art ( DE 38 41 470 A1 the applicant). Notwithstanding the prior art, 2 recesses 11 are formed on the inside of the lid, in which engage the flat tubes 8, not shown here with their narrow sides. The recesses 11 are thus arranged at a distance from the pipeline. Through the recesses 11, the width of the coolant box 1 can be reduced.

Fig. 3 zeigt ein Segment des Bodens 3 in einer Ansicht von der Seite des nicht dargestellten Blockes, d. h. mit Blick auf die so genannte Luftseite des Bodens 3. Man erkennt die quer zum Boden 3 verlaufenden Versteifungssicken 9, welche zwischen den Durchzügen 7 angeordnet sind, wobei die Durchzüge eine Einführschräge 7a aufweisen. Die hier nicht dargestellten Rohre 8 werden also von der Luftseite her in die Durchzüge 7 des Bodens 3 eingeführt. Im mittleren Bereich des Bodensegmentes 3 sind zwei Einführsicken 12 eingeformt, welche bis an die Rinne 4 heranreichen und hier als Vertiefungen erscheinen. Fig. 3 shows a segment of the bottom 3 in a view from the side of the block, not shown, ie with a view to the so-called air side of the bottom 3. It can be seen extending transversely to the bottom 3 stiffening beads 9, which are arranged between the passages 7, wherein the Passages have an insertion bevel 7a. The pipes 8 not shown here are therefore introduced from the air side in the passages 7 of the bottom 3. In the middle region of the bottom segment 3, two insertion beads 12 are formed, which reach as far as the groove 4 and appear here as depressions.

Fig. 4 zeigt das Bodensegment gemäß Fig. 3 um 180° gedreht, d. h, mit Blick auf die "Kühlmittelseite" des Bodens 3. Man erkennt, dass die Durchzüge 7 zur Kühlmittelseite hin (in der Zeichnung nach oben) aus dem Bodenbereich 3a ausgeformt sind. Im mittleren Bereich (in Längsrichtung des Bodens 3 betrachtet) sind die beiden Einführsicken 12, hier erhaben ausgeformt, erkennbar. Die beiden Einführsicken 12 reichen bis an die innere Wand 4a der Rinne 4 und haben die Funktion, den Deckel 2 bzw. dessen Flansch 6 beim Einsetzen in die Rinne 4 aufzuweiten oder zu spreizen. Bedingt durch den Spritzvorgang beim Herstellen des Deckels 2 kann es vorkommen, dass die lichte Weite des Deckels 2 reduziert ist, der Deckel 2 ist "eingefallen". Damit bei der Montage d. h. beim Schließvorgang von Deckel 2 und Boden 3 kein Klemmen auftritt, wird durch die beiden Einführsicken 12 das Einführen des Deckels 2 in die Rinne 4 erleichtert. Fig. 4 shows the ground segment according to Fig. 3 rotated 180 °, d. h, looking at the "coolant side" of the bottom 3. It can be seen that the passages 7 towards the coolant side (in the drawing upwards) from the bottom area 3a are formed. In the central region (viewed in the longitudinal direction of the bottom 3), the two insertion beads 12, here raised, can be seen. The two Einführsicken 12 extend to the inner wall 4a of the channel 4 and have the function to expand the lid 2 and its flange 6 when inserted into the channel 4 or to spread. Due to the injection process in the manufacture of the lid 2, it may happen that the inside width of the lid 2 is reduced, the lid 2 is "collapsed". So that during assembly ie during the closing process of the lid 2 and bottom 3 no clamping occurs, the insertion of the lid 2 is facilitated by the two Einführsicken 12 in the trough 4.

Fig. 5 zeigt einen Querschnitt durch den Boden 3 im Bereich der Rinne 4 und des Durchzuges 7. Das Flachrohr 8 weist ein Rohrende 8a auf, welches von dem Durchzug 7 aufgenommen und stoffschlüssig mit dem Durchzug 7 verbunden ist. Die Rinne 4 wird durch die innere Wand 4a mit der Wandstärke x2 und die äußere Wand 4b mit der Wandstärke x3 begrenzt, wobei zwischen der Wand 4a und der Wand 4b eine lichte Weite mit dem Maß x4 belassen ist. Zwischen dem Rohr 8 und der inneren Wand 4a ist ein Spalt 13 belassen, der mit dem Maß x1 gekennzeichnet ist. Die Summe der Maße x1, x2, x3, x4 ergibt das Gesamtmaß X, welches den so genannten Überstand des Kühlmittelkastens 1 bzw. des Bodens 3 gegenüber dem Block des Kühlmittelkühlers kennzeichnet, wobei für die Stirnseite des Blockes hier das Rohr 8 repräsentativ ist. Die hier geschnittene Schmalseite des Flachrohres 8 liegt in der Stirnfläche des Blockes. Erfindungsgemäß sind die dargestellten Maße x1 bis x4 in der Weise optimiert, d. h. im Wesentlichen verkleinert, dass das Gesamtmaß X, also der Überstand möglichst klein wird. Das Maß x1 für den Spalt 13 ist gegenüber dem Stand der Technik reduziert und weist einen Bereich von 0,1 bis 0,5 mm auf. Das Maß x4, d. h. die lichte Weite der Rinne 4, wurde gegenüber dem Stand der Technik um 0,5 mm reduziert. Die Wandstärke x2 der inneren Wand 4a wurde gegenüber der Wandstärke x3 der äußeren Wand 4b um 0,1 bis 0,3 mm reduziert, d. h. x2 = x3 - 0,2. Die Wandstärke x3 der äußeren Wand 4b entspricht der Wandstärke des Blechmaterials für den Boden 3, während die innere Wand 4a somit eine geringere, im Durchschnitt 0,2 mm geringere Wandstärke aufweist, was bei der Herstellung des Bodens 3 beispielsweise durch Strecken des Materials erreicht werden kann. Durch die Reduzierung der lichten Weite x4 ist auch eine Reduzierung der Maße x5 für den Flansch 6 und x6 für den Durchmesser der Dichtung 5 erforderlich. Die Reduzierung des Flanschmaßes x5 war auch infolge der Anordnung der Aussparungen 11 auf der Innenseite des Deckels 2 möglich. Somit sind die Maße x1, x2, x4 gegenüber dem Stand der Technik reduziert, woraus sich insgesamt eine Reduzierung für den Überstand X ergibt - aufgrund der erfindungsgemäßen Maßnahmen konnte der Überstand X auf ca. 6 mm reduziert werden. Der Kühlmittelkühler 1 weist somit einen beidseitigen Bodenüberstand von insgesamt ca. 12 mm auf. Fig. 5 shows a cross section through the bottom 3 in the region of the channel 4 and the passage 7. The flat tube 8 has a pipe end 8a, which is received by the passage 7 and materially connected to the passage 7. The channel 4 is bounded by the inner wall 4a with the wall thickness x2 and the outer wall 4b with the wall thickness x3, wherein a clear width of the dimension x4 is left between the wall 4a and the wall 4b. Between the tube 8 and the inner wall 4a, a gap 13 is left, which is marked with the dimension x1. The sum of the dimensions x1, x2, x3, x4 gives the total dimension X, which characterizes the so-called projection of the coolant box 1 or the bottom 3 relative to the block of the coolant radiator, wherein for the front side of the block here the tube 8 is representative. The cut here narrow side of the flat tube 8 lies in the end face of the block. According to the invention, the illustrated dimensions x1 to x4 are optimized in the manner, ie, substantially reduced, such that the overall dimension X, that is to say the supernatant, becomes as small as possible. The dimension x1 for the gap 13 is reduced over the prior art and has a range of 0.1 to 0.5 mm. The dimension x4, ie the inside width of the channel 4, has been reduced by 0.5 mm compared to the prior art. The wall thickness x2 of the inner wall 4a has been reduced by 0.1 to 0.3 mm compared to the wall thickness x3 of the outer wall 4b, ie x2 = x3 - 0.2. The wall thickness x3 of the outer wall 4b corresponds to the wall thickness of the sheet material for the bottom 3, while the inner wall 4a thus has a smaller, on average 0.2 mm smaller wall thickness, resulting in the production of the bottom 3, for example by stretching the material can be achieved. By reducing the clear width x4, a reduction of the dimensions x5 for the flange 6 and x6 for the diameter of the seal 5 is required. The reduction of the Flanschmaßes x5 was also possible due to the arrangement of the recesses 11 on the inside of the lid 2. Thus, the dimensions x1, x2, x4 are reduced compared to the prior art, resulting in a total reduction for the supernatant X - due to the inventive measures, the supernatant X could be reduced to about 6 mm. The coolant radiator 1 thus has a bilateral floor overhang of a total of about 12 mm.

Fig. 6 zeigt eine weitere Darstellung eines Ausschnittes des Bodens 3 mit einer umlaufenden Randleiste 13, welche der äußeren Wand 4b der Rinne 4 in den vorangegangenen Figuren entspricht. Aus der Randleiste 13 sind Langlöcher oder Schlitze 14 ausgestanzt, damit der Boden 3 durch eine so genannte Wellenschlitzbördelung - wie sie in dem eingangs genannten Stand der Technik beschrieben ist - mit dem Flansch 4 des Deckels 2 verbunden werden kann. Fig. 6 shows a further illustration of a section of the bottom 3 with a circumferential edge strip 13, which corresponds to the outer wall 4b of the channel 4 in the preceding figures. From the skirt 13 slots or slots 14 are punched out, so that the bottom 3 by a so-called Wellenschlitzbördelung - as described in the aforementioned prior art - can be connected to the flange 4 of the lid 2.
