che 5 im Verhältnis zu deren Länge relativ klein ist. Die lichte Breite des Rohrs soll 3-5 mm betragen bei einer aussen gemessenen Höhe des Flachrohrs von ca. 70 mm. Das Rohr weist eine Blechstärke von 1,25 bis höchstens 2,0 mm auf. Bei diesem extrem flachen Rohr ist das Verhältnis der Innenquerschnittsfläche zum äusseren Rohrumfang kleiner oder gleich 2,5 mm. Über die Rohrlänge gerechnet gilt der gleiche Wert für das Verhältnis des Wasservolumens im Rohr zur äusseren Heizfläche des Rohrs. Ein kleiner Wert bedeutet hier im Vergleich mit grösseren Rohrquerschnitten bei bekannten Wärmeaustauschern, dass die auf ein gleiches Wasservolumen bezogene Heizfläche grösser ist und die Wärmeabgabe des Heizkörpers daher besser ist. Da andererseits in dem flachen Rohr weniger Wasser enthalten ist, das mit grösserer Geschwindigkeit hindurchströmt, ist die thermische Trägheit des Heizkörpers merklich geringer. Die Dimensionierung der Flachrohre lässt demnach verschiedene Vorteile im Hinblick auf eine bessere Energienutzung erzielen. che 5 is relatively small in relation to its length. The clear width of the pipe should be 3-5 mm with an outside height of the flat pipe of approx. 70 mm. The tube has a sheet thickness of 1.25 to at most 2.0 mm. In this extremely flat pipe, the ratio of the inner cross-sectional area to the outer pipe circumference is less than or equal to 2.5 mm. Calculated over the pipe length, the same value applies to the ratio of the water volume in the pipe to the outer heating surface of the pipe. A small value here, in comparison with larger pipe cross sections in known heat exchangers, means that the heating surface, based on the same water volume, is larger and the heat output of the radiator is therefore better. On the other hand, since there is less water in the flat tube flowing through it at a higher speed, the thermal inertia of the radiator is markedly lower. The dimensioning of the flat tubes can therefore achieve various advantages with regard to better energy use.
Die in grösseren Längen hergestellten Flachrohre werden je nach Bedarf abgelängt und an den stirnseitigen Enden verschlossen, was bei den sehr flachen Rohren in vorteilhafter Weise durchführbar ist. Fig. 4 zeigt eine Ausführungsform, bei der die Flachrohre an den stirnseitigen Enden jeweils durch zur Mitte einwärts gebogene Randzonen 6 der einander gegenüberliegenden Rohrbreitseiten und durch eine diese Randzonen verbindende Schweissnaht 7 verschlossen sind. Bei der Ausführungsform gemäss Fig. 5 sind die Flachrohre an den stirnseitigen Enden jeweils durch eine Randzone 8 der einen Rohrbreitseite, welche bis zur gegenüberliegenden Rohrbreitseite des mit Ausnahme der genannten Randzone 8 längs des Umfanges verkürzten Flachrohrs einwärts gebogen ist, und durch eine die Randzone mit der genannten Rohrbreitseite verbindende Schweissnaht 9 verschlossen. Da die Flachrohre in den Fig. 4 und 5 in grösserem Massstab dargestellt sind, während sie in Fig. 2 und 3 etwa in ihrer natürlichen Grösse abgebildet sind, ist es einleuchtend, dass man die sehr flachen Rohre mit einer Schweissnaht verschliessen kann, wobei an den etwas geschlitzten Schmalseiten des Rohrs ein etwas dickerer Schweisspunkt an den Schweiss-nahtenden zum restlosen Zuschweissen des Rohrs genügt. Es ist daher mit verhältnismässig wenig Herstellungsaufwand auf diese Weise möglich, die aus ästhetischen Gründen bevorzugte Konstruktion eines Wärmeaustauschers mit an der rückwärtigen Seite einwärts im Abstand von den Flachrohrenden angeordneten Sammelrohren zu verwirklichen. Eine Konstruktion mit an den Enden der Flachrohre angeordneten Sammelrohren, in welche die Flachrohre einzuschweissen sind, erfordert nämlich mehr Arbeitsaufwand und ist wegen der durch das grössere Sammelrohr bedingten Verdickung an den beiden Enden in ästhetischer Hinsicht weniger befriedigend. The flat tubes produced in greater lengths are cut to length as required and closed at the front ends, which can be carried out in an advantageous manner with the very flat tubes. FIG. 4 shows an embodiment in which the flat tubes are closed at the front ends by edge zones 6, which are bent inwards towards the center, of the opposite tube broad sides and by a weld seam 7 connecting these edge zones. In the embodiment according to FIG. 5, the flat tubes are in each case at the front ends by an edge zone 8 of one tube broad side, which is bent inwards up to the opposite tube broad side of the flat tube shortened along the circumference with the exception of the edge zone 8 mentioned, and by an edge zone with welded seam 9 connecting said broad pipe side is closed. 4 and 5 are shown on a larger scale, while they are shown in their natural size in FIGS. 2 and 3, it is obvious that the very flat tubes can be sealed with a weld seam, whereby at the slightly slit narrow sides of the pipe, a somewhat thicker welding point at the weld seam ends is sufficient for the complete welding of the pipe. It is therefore possible with relatively little manufacturing effort in this way to implement the construction of a heat exchanger, which is preferred for aesthetic reasons, with collecting tubes arranged on the rear side inwards at a distance from the flat tube ends. A construction with collecting pipes arranged at the ends of the flat pipes, into which the flat pipes are to be welded, requires more work and is less aesthetically satisfactory because of the thickening at the two ends due to the larger collecting pipe.
Für den Anschluss der Flachrohre 1 an die Sammelrohre 2 sind gemäss Fig. 2 und 3 in dem Sammelrohr 2 Wanddurchbrechungen bzw. Bohrungen 10 ausgebildet und ist der die Wanddurchbrechung umgebende Wandbereich 11 entweder gemäss Fig. 2 stufenförmig nach aussen gedrückt oder in anderer Weise der Wandbereich 12 gemäss Fig. 3 trichterförmig 5 nach aussen gedrückt. Koaxial zu jeder der Wanddurchbrechungen bzw. Bohrungen 10 weisen die Flachrohre 1 im Durchmesser kleinere Wanddurchbrechungen bzw. Bohrungen 13 auf. Ein diese jeweils umgebender Wandbereich 14 des Flachrohrs 1 ist mit dem nach aussen gedrückten Wandbe-io reich 11 gemäss Fig. 2 oder 12 gemäss Fig. 3 verschweisst. Die nur in Fig. 4 und 5 dargestellte Schweissnaht 15 ist in Fig. 2 und 3 zur Verdeutlichung nicht eingezeichnet. Zwischen den Flachrohren 1 und dem Sammelrohr 2 verbleibt auch nach der Schweissung ein durch den nach aussen gedrückten 15 Wandabschnitt 11 bzw. 12 sich ergebender geringer Abstand, der es möglich macht, dass eine eventuell als undicht festgestellte Schweissverbindung nachträgüch noch von aussen durch einen um den Anschluss herum gelegten Ring und durch Löten dicht gemacht werden kann. 20 Die Verbindung der Flachrohre 1 mit den Sammelrohren 2 durch die Schweissnaht 15 erfolgt von der Innenseite der Sammelrohre aus, wie aus Fig. 4 und 5 hervorgeht. Um dies zu ermöglichen, besteht jedes Sammelrohr 2 aus mindestens zwei über die Rohrlänge sich erstreckenden Teilen, und zwar 25 gemäss Fig. 4 aus einem im Querschnitt U-förmig ausgebildeten Teil 20 und aus einem deckelartigen Teil 21, die nach Fertigstellung aller Schweissverbindungen mit sämtlichen Flachrohren durch über die ganze Sammelrohrlänge verlaufende Schweissnähte 22 miteinander verbunden werden. Bei der 3C Ausführungsform nach Fig. 5 sind zwei gleiche im Querschnitt U-förmig ausgebildete Teile 23 und 24 des Sammelrohrs 2 durch die beiden Schweissnähte 25 miteinander verbunden. Bezüglich dieser Sammelrohrteile bestehen natürlich viele weitere Formgebungsmöglichkeiten, insbesondere kann 35 zur Erleichterung des Zusammenfügens der Teile der eine Teil einen stufenförmig etwas einwärts gedrückten Rand aufweisen, den der andere Teil deckelartig übergreift. For the connection of the flat tubes 1 to the header tubes 2, wall openings or bores 10 are formed in the header tube 2 according to FIGS. 2 and 3, and the wall area 11 surrounding the wall aperture is either pressed outwards in a step-like manner according to FIG. 2 or in another way the wall area 12 according to FIG. 3 funnel-shaped 5 pressed outwards. Coaxial to each of the wall openings or bores 10, the flat tubes 1 have wall openings or bores 13 which are smaller in diameter. A wall region 14 of the flat tube 1 surrounding this in each case is welded to the wall region 11 which is pushed outwards, as shown in FIG. 2 or 12 as shown in FIG. 3. The weld seam 15 shown only in FIGS. 4 and 5 is not shown in FIGS. 2 and 3 for clarification. Between the flat tubes 1 and the header tube 2, even after welding, there remains a small distance resulting from the outwardly pressed wall section 11 or 12, which makes it possible for a weld connection which may have been found to be leaky to be subsequently removed from the outside by one around the Connection ring placed around and can be sealed by soldering. 20 The connection of the flat tubes 1 to the header tubes 2 by means of the weld seam 15 takes place from the inside of the header tubes, as can be seen from FIGS. 4 and 5. In order to make this possible, each header pipe 2 consists of at least two parts extending over the pipe length, specifically 25 according to FIG. 4 of a part 20 with a U-shaped cross section and of a cover-like part 21, which after completion of all welded connections with all Flat tubes are connected to one another by weld seams 22 extending over the entire length of the collecting tube. In the 3C embodiment according to FIG. 5, two identical parts 23 and 24 of the collecting tube 2, which are U-shaped in cross section, are connected to one another by the two weld seams 25. With regard to these manifold parts, there are of course many other shaping options, in particular, in order to facilitate the joining of the parts, one part can have a step-shaped slightly pressed-in edge, which the other part engages over in a cover-like manner.
Mit einem aus mindestens zwei Teilen bestehenden Sammelrohr lässt sich nach der vorstehend beschriebenen Me-40 thode auch ohne Schwierigkeiten ein Wärmeaustauscher gemäss Fig. 6 mit auf gegenüberliegenden Seiten der Sammelrohre angeordneten Flachrohren herstellen. Bei diesem Wärmeaustauscher werden bei jedem der beiden Teile des Sammelrohrs erst die Anschlüsse an die jeweils übereinander an-45 geordneten Flachrohre durch Schweissen hergestellt und anschliessend die beiden Teile des Sammelrohrs zusammenge-schweisst. In dem Zwischenraum zwischen den auf der einen und der gegenüberliegenden Seite der Sammelrohre angeordneten Flachrohren ist bei dem Wärmeaustauscher gemäss 50 Fig. 6 zusätzlich ein vielfach abgewinkeltes Konvektorblech 30 angeordnet. Ein solches Konvektorblech kann auch bei nur auf einer Seite der Sammelrohre angeordneten Flachrohren an deren rückwärtiger Seite fest angeordnet sein. With a manifold consisting of at least two parts, a heat exchanger according to FIG. 6 with flat tubes arranged on opposite sides of the manifolds can also be produced without difficulty according to the method described above. With this heat exchanger, the connections to the flat tubes arranged one above the other are first made by welding in each of the two parts of the header and then the two parts of the header are welded together. In the space between the flat tubes arranged on one and the opposite side of the header tubes, a multiple angled convector plate 30 is additionally arranged in the heat exchanger according to FIG. 6. Such a convector plate can also be fixedly arranged on the rear side of flat tubes arranged only on one side of the collecting tubes.
