Abstract

The method forms a heat conductive joint between a pipe containing a heat transfer medium and a flat heater body, by clamping the latter to the pipe, to form a sidewall heater in a bus. The pipe (5) is first aligned for height by the inner supporting face (8) of a channel section extruded component (6). The body (4) is then lowered onto the pipe bearing against an end flange (9) on the extruded component. A profiled portion (11) with ramp face (10) on the body aligns the pipe in the vehicle lengthwise direction. Finally a wedge with a recess (15) towards the pipe and a locking lip (17) is pressed home between the pipe and a supporting surface (13) on the extruded component, on the opposite side to the profiled portion. ADVANTAGE - Maximum rate of heat transfer, while requiring little effort for installation or removal.

Description

Die Erfindung betrifft ein Verfahren zum Herbeiführen einer wärmeleitenden Verbindung zwischen einem einen Wärmeträger auf­ nehmenden Rohr und einem Flächenheizkörper durch mittels eines Spannelementes hervorgerufener flächiger Anlage des Rohres am sich beim Absenken abstützenden Flächenheizkörper zum Erhalt einer Seitenwandheizung in einem Omnibus.The invention relates to a method for bringing about a thermally conductive connection between a heat transfer medium taking pipe and a panel radiator by means of a Clamping element caused flat contact of the pipe on panel radiators that support the lowering for preservation a side wall heater in a bus.

Durch die DE-PS 31 04 069 ist es bekannt, die wärmeleitende Verbindung zwischen einem Ovalrohr und dem als Wärmerohr aus­ gebildeten Flächenheizkörper mittels in kurzem Abstand aufein­ anderfolgender biegeharter Klemmfedern herbeizuführen. Die Klemmfedern müssen verliersicher möglichst dem Ovalrohr zuge­ ordnet sein und sich z. B. bodenseitig abstützen, damit bei dem mit hoher Kraftanwendung unter Aufspreizen der Klemmfedern er­ folgenden Niederdrücken des Flächenheizkörpers das Ovalrohr eine Ausrichtung beibehält, die eine flächige Anlage zwischen Flächenheizkörper und Ovalrohr sicherstellt. Trotzdem kann es vorkommen, daß selbst bei hoher Klemmfederfolge im Bereich zwi­ schen zwei aufeinanderfolgenden Klemmfedern der Wärmeübergang zwischen Ovalrohr und Flächenheizkörper infolge nicht ausrei­ chender Anlage nicht das erforderliche Maß erreicht.From DE-PS 31 04 069 it is known that the heat conductive Connection between an oval tube and the as a heat pipe formed radiators by means of a short distance to bring about the following bending hard clamping springs. The Clamping springs must be secured against the oval tube so that they cannot be lost be organized and z. B. support on the bottom so that with high application of force while spreading the clamping springs following depressing the panel radiator the oval tube maintains an orientation that a flat plant between Surface radiator and oval tube ensures. Still it can happen that even with a high clamping spring sequence in the area between heat transfer between two successive clamping springs between oval tube and panel radiator is not sufficient as a result system does not reach the required level.

Der Erfindung liegt die Aufgabe zugrunde die Montage und Demontage weniger kraftraubend zu gestalten und durch flächige Anlage des Rohres am Flächenheizkörper über die ganze Anlagelänge hinweg ein Größt­ maß an Wärmeübergang zu erreichen. The invention has for its object the assembly and disassembly less designed to take up a lot of energy and through flat contact of the pipe one of the largest on the panel radiator over the entire length of the system degree of heat transfer.  

Diese Aufgabe wird durch die im Kennzeichen des Patentanspru­ ches 1 angegebenen Verfahrensschritte gelöst, wobei es beson­ ders vorteilhaft ist, daß ohne besondere Kraftanwendung der Flächenheizkörper erst in eine lagesichere Zuordnung zum Rohr gebracht wird und zuletzt erst durch den Kederstreifen eine fortschreitende flächige Anlage zwischen Flächenheizkörper und Rohr bei geringem Kraftbedarf erfolgt. Durch die am Kederstrei­ fen angeformte Grifflippe läßt sich die Verbindung im Bedarfs­ fall ebensoleicht wieder lösen.This task is by the in the characterizing part of the patent Ches 1 specified process steps, wherein it particular ders is advantageous in that the Surface radiators only in a secure position with the pipe is brought and finally only by the piping strip progressive flat system between panel radiators and Pipe takes place with low power requirements. By the keder streak The molded grip lip allows the connection to be made as required just solve the case again.

Eine nach der Erfindung geschaffene wärmeübertragende Verbin­ dung zwischen einem wärmeträgerführenden Rohr und einem Flä­ chenheizkörper ist in der Zeichnung dargestellt und wird nach­ folgend näher erläutert.A heat transfer connector created according to the invention between a heat transfer pipe and a surface Chen radiator is shown in the drawing and is after explained in more detail below.

Einer nicht näher dargestellten, aus einem Gerippe 1 und einer Beplankung 2 bestehenden Omnibus-Seitenwand 3 ist innenraum­ seitig ein Flächenheizkörper 4 vorgelagert, auf den über min­ destens ein an seinem unteren Ende in Fahrzeuglängsrichtung verlaufendes Rohr 5, das vorzugsweise von temperaturgeregeltem Kühlwasser durchflossen ist, Wärme zugeführt wird. In nicht dargestellter Weise ist aber auch eine zusätzliche obere Wär­ meeinspeisung möglich.A omnibus side wall 3 , not shown in detail, consisting of a frame 1 and a planking 2 , is preceded on the inside by a surface heating element 4 , on which a pipe 5 running at least at its lower end in the longitudinal direction of the vehicle and preferably through which temperature-controlled cooling water flows, Heat is supplied. In a manner not shown, however, an additional upper heat feed is possible.

Um die wärmeleitende Verbindung herzustellen, wird zunächst ein etwa U-förmig profiliertes Strangpreßprofil 6 auf einen vom Gerippe 1 abragenden Flansch 7 aufgeschoben, das eine Anlage­ fläche 8 als Auflager für das kühlwasserdurchflossene Rohr 5 aufweist. Zwischen dem auf diese Weise höhenmäßig festgelegten Rohr 5 und einem endseitigen Schenkel 9 des Strangpreßprofils 6 wird der Flächenheizkörper 4 von oben her eingeschoben, wobei die Anlaufschräge 10 eines mit dem Flächenheizkörper 4 verbun­ denen Anlageprofiles 11 das Rohr 5 zur Seite drückt, bis dieses von einer zugeordneten Stützfläche 12 des Anlageprofiles 11 teilweise umfaßt wird.In order to produce the heat-conducting connection, an approximately U-shaped extruded profile 6 is first pushed onto a flange 7 which projects from the frame 1 and which has a bearing surface 8 as a support for the tube 5 through which cooling water flows. Between the height-fixed tube 5 and an end leg 9 of the extruded profile 6 , the panel heater 4 is inserted from above, the run-up slope 10 of a unit with the panel heater 4 connecting system profile 11 pushes the tube 5 to the side until one of them assigned support surface 12 of the contact profile 11 is partially included.

Zur Sicherung dieser Zuordnung von Rohr 5 und Anlageprofil 11 wird zwischen einer Stützfläche 13 des Strangpreßprofiles 6 und dem Rohr 5 ein Spannelement 14 in Form eines ein keilförmiges Profil mit rohrseitiger Ausnehmung 15 aufweisenden Kederstrei­ fens 16 eingedrückt, wobei durch fortschreitendes Eindrücken nur ein relativ geringer Kraftaufwand notwendig ist.To secure this assignment of tube 5 and contact profile 11 , a clamping element 14 in the form of a wedge-shaped profile with a tube-side recess 15 having Kederstrei fens 16 is pressed between a support surface 13 of the extruded profile 6 and the tube 5, only a relatively small amount of force being applied by progressive pressing necessary is.

Oberseitig des Kederstreifens 16 ist eine Grifflippe 17 ange­ formt, bei deren Ziehen der Kederstreifen 16 z. B. zum Zwecke eines Austausches eines Flächenheizkörpers 4 gelöst wird. Auch dieser Arbeitsgang fordert keinen großen Kraftaufwand.On the top of the piping strip 16 is a grip lip 17 is formed , when pulling the piping strip 16 z. B. is solved for the purpose of replacing a panel heater 4 . This operation also does not require much effort.

Überdeckt und dadurch geschützt wird das Rohr 5 durch ein Ver­ kleidungselement 18, das sich über eine Lippe 19 am Flächen­ heizkörper 4 abstützt und unter Einsatz von Haltefedern 20, von denen nur eine ersichtlich ist, an der Stützfläche 13 gehalten ist. Zum Austritt von Warmluft kann das Verkleidungselement 18 oberseitig mit nicht dargestellten Öffnungen versehen sein und über gleichfalls nicht gezeigte Öffnungen kann der durch das Verkleidungselement 18 nach obenhin begrenzte Raum 21 belüftet sein.Covered and thereby protected, the tube 5 is covered by a United clothing element 18 , which is supported by a lip 19 on the radiator surface 4 and is held on the support surface 13 using retaining springs 20 , only one of which can be seen. For the escape of warm air, the cladding element 18 can be provided on the upper side with openings, not shown, and the space 21, which is delimited at the top by the cladding element 18, can also be ventilated via openings which are also not shown.
