Abstract

A heat exchanger is constructed from Al sheet (I) and Cu tubes (2). The tubes (2) are attached to the plate (1) by clamps (3) made of steel wire. The clamps (3) are U-shaped with the ends (4) of the legs bent outwards. The clamps (3) are fitted over the tubes (2) and the turned out portions (4) are pressed or rolled into the sheet (1) so that they are firmly embedded. The clamps (3) are supplied attached to a strip (5) of paper or plastic for ease of handling. Alternatively the clips may be formed from a continuous length of wire.

Description

Titel: Verfahren zur Herstellung von Warmetausetler-Title: Process for the production of heat exchanger

platten sowie danach hergestellte Wärmetauscherplatten Beschreibung Die Erfindung betrifft ein Verfahren zur Herstellung von Wärmetauscherplatten sowie danach hergestellte Warmetauscherplatten, welche aus Rohren für das Wärlue tauschmedium bestehen, die mit einer Metallplatte verbunden sind. plates as well as heat exchanger plates manufactured according to this description The invention relates to a method for producing heat exchanger plates as well then produced heat exchanger plates, which are made of tubes for the heat exchange medium which are connected to a metal plate.

Derartige Plattenelemente werden sowohl als Sonnenkollektoren, als auch als Wärmetauscher und HeizungseRement bei Fußboden-, Wand- und Deckenheizungen verwendet, wobei die Metallplatte die Aufgabe hat, die vom Rohr abgegebene Wärme zu sammeln bzw. zu verteilen Da das Rohr häufig aus anderem Werkstoff besteht als die Platte und Klebungen, Schweißungen und Lötungen aber zu teuer kommen, werden häufig metallische Verbindungselemente in Form von Schellen, Blechlamellen u.dgl. verwendet, welche das Rohr umschließen und durch Nietungen od.dgl. mit der Blechplatte verbunden werden, Bei der Vielzahl der Befestigungsstellen ist aber auch dies ein zu aufwendiger Vorgang, weshalb erfindungsgemäß vorgeschlagen wird, die Verbindung über eine das Rohr umhüllende Blechlamelle oder Drahtgitter bzw. Span gen vorzunehmen, welche mit ihren Randbereichen in die Blechplatte eingewalzt bzw. gepreßt sind.Such plate elements are both as solar panels, as Also as a heat exchanger and heating element for underfloor, wall and ceiling heating used, the metal plate has the task of the heat given off by the pipe to collect or distribute Since the pipe is often made of a different material than the plate and adhesives, welds and soldering will be too expensive often metallic connecting elements in the form of clamps, sheet metal lamellas and the like. used, which enclose the pipe and the like by riveting. with the sheet metal plate However, with the large number of fastening points, this is also one too expensive process, which is why it is proposed according to the invention, the connection to be carried out using a sheet metal lamella or wire grating or tension that surrounds the pipe, which are rolled or pressed with their edge areas into the sheet metal plate.

Dieser Vorgang kann kalt mit einem einzigen Werkzeug erfolgen, das im Durchlaufverfahren eine Vielzahl der- artiger Verbindungen gleichzeitig ausführt, wobei neben dem Kaltpreßschweißen bei gleichartigen Metallen auch verschiedenartige miteinander nicht verschweißbare Metalle durch Einbetten verbunden werden. Es wird dabei vorzu#sweise das härtere Metall der Schelle in das weichere Metall der Platte eingepreßt.This process can be done cold with a single tool, the a multitude of these like connections at the same time executes, in addition to cold pressure welding with similar metals also different types non-weldable metals are connected by embedding. It will Preferably the harder metal of the clamp into the softer metal of the plate pressed in.

Die Erfindung ist in der Zeichnung beispielsweise dargestellt. Es zeigen: Fig. 1 eine Spangenbefestigung, Fig. 2 eine Befestigung mittels einer Blechlamelle mit ausgestanzten Pratzen, Fig. 3 eine Befestigung einer Blechlamelle mit eingestanzten Löchern und Fig. 4 eine Befestigung mittels eines Drahtgitters.The invention is shown in the drawing, for example. It 1 shows a clip fastening, FIG. 2 shows a fastening by means of a sheet metal lamella with punched out claws, Fig. 3 a fastening of a sheet metal lamella with punched Holes and FIG. 4 shows an attachment by means of a wire mesh.

Fig. 5, 6,7 und 8 stellen jeweils zugeordnete Querschnitte dar.FIGS. 5, 6, 7 and 8 each represent associated cross-sections.

Wie man aus der Zeichnung Fig. 1 bzw. 5 ersehen kann, ist ein auf einem Grundblech 1 (Absorberblech) aufgelegtes Rohr 2 mittels der auf einem Papier oder Kunststoffband 5 aufgereihten Drahtklammern 3 durch Einpressen der Klammerenden 4 in das Grundblech 1 befestigt.- Es kann dabei das Rohr aus Kupfer, die Klammern aus Eisen und das Grundblech aus Aluminium bestehen, wobei die härteren Eisenklammerenden beim Einpressen in das Aluminium durch Fließen desselben umfaßt und damit# festgehalten werden.As can be seen from the drawing Fig. 1 and 5, a is on a base plate 1 (absorber plate) placed pipe 2 by means of the on a paper or plastic tape 5 lined up wire clips 3 by pressing in the clip ends 4 fastened in the base plate 1. - It can be the pipe made of copper, the brackets made of iron and the base plate made of aluminum, with the harder iron clip ends when pressed into the aluminum by flowing the same and thus # held will.

Bei der Ausführung nach Fig. 2 bzw. 6 ist der Vorgang und die Funktion ähnlich wie bei Fig. i, wobei statt der Drahtklammern eine Blechlamelle 3' mit beliebig -ausgestanzten Kanten, deren Enden 4t eingepreßt werden, verwendet wird. Bei der Ausführung gemäß Fig. 3 bzw. 7 wird ebenfalls eine Blechlamelle 3t zur Befestigung des Rohres 2 verwendet, wobei der Grat 6 von in der Lamelle 3' befindlichen durchgerissenen Löchern 5 in das Grundblech i eingepreßt'wird. Bei der Variante gemäß Fig. 4 bzw-. 8 wird Draht in Leiterform 3 verwendet, wobei die Holme 4" in das Grundblech i eingepreßt werden; aber auch schlangenformig gebogener Draht sowie Gitterstreifen wären denkbar. Alle diese Verbindungsvarianten sind natürlich für Rohre verschiedenen Durchmessers und Profils (Fig. 8 zeigt ein abgeflachtes Rohr zur Verbesserung des Wärmeübergangs) verwendbar, wobei eine Profilveränderung des Rohres z.B. Flachdrücken gemäß Fig. 6 auch während des Einpressens der Befestigungselemente vorgenommen werden kann.In the embodiment according to Fig. 2 and 6, the process and the function similar to Fig. i, where instead of the wire clips a sheet metal lamella 3 'with any -punched edges, the ends of which are pressed in 4t, is used. In the The embodiment according to FIG. 3 or 7 is also a sheet metal lamella 3t for fastening of the tube 2 is used, the ridge 6 being torn through located in the lamella 3 ' Holes 5 are pressed into the base plate i. In the variant according to FIG. 4 or. 8 wire in ladder shape 3 is used, with the stiles 4 "into the Base plate i are pressed in; but also serpentine bent wire as well Grid strips would be conceivable. All these connection variants are of course for Tubes of various diameters and profiles (Fig. 8 shows a flattened tube to improve the heat transfer) can be used, whereby a profile change of the Pipe e.g. flattening according to Fig. 6 also during the pressing in of the fastening elements can be made.
