Es ist bekannt, Flachheizkörpsr aus Kunststoff mit horizontalen Verteilerkanälen und vertikalen, rohrförmigen Verbinduiigskanälen herziist eilen. Je nach Art det·. Materials können die Teile durch Pressen, Extrudieren, Spritzgießen, Tüxtrucionsblasen oder ähnliche Verfahren erzeugt werden. Besonders bewährt hat sich das Extrusionsblasen, bei dem Heizkörperelemente in einem Stück hergestellt werden,. die dann zum fertigen Heizkörper zusammengeschweißt und konfektioniert werden. Dabei, wird ein extrudiertos Sc.hlauchstück in einer teilbaren Form durch Innendruck an die Wände d?r ?cm gedi-ückt. N?ch dem Abkühlen kann da-s fercige Element entiorint werden. Bei etv/a gleichem AufblixaverhalxniG dpr vorschitsdeneii Kanälen entstehen dabsi Heizkörper niit gleichen Vi and star ken aller Teile. Falls erwünscht können bestimmte Zonon durch die- bekannte Wanddickenregulierung des extrudierteu .Schlauchstückes verstärkt werden. • .Kleinere Heiakörper können so auch in eineni Stück hergestellt .y/erden.It is known that flat heating elements made of plastic with horizontal distribution ducts and vertical, tubular connection ducts rush to the heart. Depending on the type of det ·. Material, the parts can be produced by pressing, extrusion, injection molding, extrusion blowing or similar processes. Blow molding, in which radiator elements are manufactured in one piece, has proven particularly successful. which are then welded together to form the finished radiator and assembled. In this case, an extruded hose piece in a divisible shape is pressed against the walls by more than ½ cm by internal pressure. After cooling down, the ferrous element can be entiorinted. With approximately the same amount of flashing and pre-cut ducts, radiators with the same thickness of all parts are created. If desired, certain zones can be reinforced by the known wall thickness regulation of the extruded tube piece. • Smaller heating bodies can also be produced in one piece .y / earth.

da hier infolge der geometrischen Überschneidungen Schwachstellen auftreten.because weak points occur here due to the geometric overlap.
Es wurde bereits vorgeschlagen, diesen Nachteil dadurch zu. beheben, daß sich die rohrförmigen Verbindungskanäle am Übergang zu den horizontalen Verteilerkanälen konisch verjüngen. Die Festigkeit in diesem Bereich wird se vergrößert und gleichzeitig die Steifigkeit des gesamten Heizkörpers verbessert. Ein weiterer Vorteil dieser Ausbildung besteht darin, daß die Schweizstelle an den Verteilerkanälen zwischen benachbarten Einmündungen dsr Yerfoindungskanäle verlängert ist. Dieso Verlängerung der Schweißstelle führt zu einer Verbesserung der Festigkeit an der Übergangsstelle zwischen den Verteiler- und Vorbindungskanälen.It has already been proposed to address this disadvantage. remedy, that the tubular connecting channels at the transition taper conically towards the horizontal distribution channels. The strength in this area is increased and at the same time improves the rigidity of the entire radiator. Another advantage of this training is that the Swiss office at the distribution channels between neighboring Junctions dsr Yerfoindungskanäle is extended. This way Lengthening the weld leads to an improvement in strength at the transition point between the manifold and prebinding channels.
Die Schweißstellen zwischen den Einmündungen der Verbir.dmigskanä'Je können ,iedoch nur begrenzt verlängert werden, da die senkrechten Wasserkanäle einen möglichst geringen Abotand nabe η sollen, um einon hohen Wirkungsgrad des Heizkörpers .r-u gewährleisten. Die so erreichbare Festigksitsvsrbesserung ist nicht immer ausreichend.The welds between the junctions of the Verbir.dmigskanä'Je can, however, only be extended to a limited extent since the vertical water channels the lowest possible subscription hub η should to a high efficiency of the radiator .r-u guarantee. The improvement in strength that can be achieved in this way is not always sufficient.
njy wurde nun gefunden, daß die Festigkeit dor Übergangsstellen zwischen Verteilerkasten und VerbindungSKanälcn wesentlich erhöht v/erden kann, wenn.sich jeweils zwei oder x&ehrera senkrechte Verbindungskanälo in der Übergangrszone vereinigen und gemeinsam in den horizontalen Verteilerkanal einmünden. Durch diese Konstruktion wird die Zahl der Einmündungen in den Verteilerkanal mindestens um die Hälfte reduziert und trotz geringem Abstand der Verbindungskanäle sind die Einmündungen in die Verteilerkcaiaie durch ausreichend lange Echwaißskellen getrennt.It has now been found that the strength of the transition points between the distribution box and the connecting ducts can be increased if there are two or x & ehrera unite vertical connecting ducts in the transition zone and open together into the horizontal distribution channel. By this construction will reduce the number of junctions in the distribution channel at least by half and despite With a small distance between the connecting channels, the confluences in the distribution kaiaie are through sufficiently long Echwaißskellen separated.

Erfindungsgegenstand ist deshalb ein Flachheizkörper aus thermoplastischem Kunststoff, bestehend aus horizontalen Verteilerkanälen und senkrechten Verbindungskanälen, der dadurch gekennzeichnet ist, daß die 7ahl der Einmündungen in die korizontalen Verteilerkanäle höchstens halb so groß ist, wie die Anzahl der senkrechten Verbinduiigskanäle. Durch die so erreichte Verlängerung der Schweiß- bzw. Quetschnähite zwischen den Einmündungen in der Üborgangszone wird die Druckfestigkeit des Heizkörpers wesentlich verbessert.The subject of the invention is therefore a flat radiator made of thermoplastic material, consisting of horizontal distribution channels and vertical connecting channels, which is characterized in that the number of junctions in the horizontal distribution channels is at most half as large as the number of vertical connecting channels. The lengthening of the weld or pinch seams achieved in this way between the junctions in the transition zone significantly improves the pressure resistance of the radiator.
Bei dem erfindungsgemäßen Heizkörper versr-v/eigt sich jeder aus dem Verteilerkanal abgehende Verbinrtungskan?! kurz hinter dem Verteilerkanal zu zwei oder mehr senkrechten Wasserkanälon.In the case of the radiator according to the invention, everyone is divorced from the Distribution channel outgoing Verbinrtungskan ?! just behind the Distribution channel to two or more vertical water channels.
Die erfindungsgemäßen Heizkörper werden aus thermoplastischen Kunststoffen hergestellt. Iv. allgemeinen werden Homo- oder Copolymerisate aus Olefinen eingesetzt. G^nz besonders bewährt haben sich Polypropylen und Copolymerisate aus Propylen mit kleinen Mengen anderer X- Olefine, denen zweckmäßig noch Stabilisatoren zugesetzt werden.The radiators according to the invention are made from thermoplastics. Iv. homo- or copolymers of olefins are generally used. Polypropylene and copolymers of propylene with small amounts of other X-olefins, to which stabilizers are expediently added, have proven particularly useful.

Durch Verbreiterung des Auslauf s (7) der Verbindungsstege (3) zwischen den sich in der Übergangczone (6) vereinigenden Verbindungskanälen wird eine weitere Erhöhung der Festigkeit erreicht.Connection channels (2) unite shortly before the confluence (5) in the distribution channel (1) in a transition zone (6). Between the junctions (5) are elongated welds (4), the cause considerable consolidation. By widening the outlet s (7) of the connecting webs (3) between the in the A further increase in strength is achieved through the connecting channels uniting the transition zone (6).
Bei der Ausprüfung zeigte dex* erfindungsgemäße Heizkörper eine erhöhte Festigkeit gegenüber Innendruck bei gleicher Wirkungsgrad wie- der bekannte Flachheizkörper, bai dem alle Verbindungslcanäle direkt in die Verteilerkanäle einmünden.In the test, dex * inventive heating elements showed increased resistance to internal pressure with the same degree of efficiency as the known flat heating elements, because all connecting channels open directly into the distribution channels.
Ein gleichmäßiger Durchfluß durch alle Verbindungskanäle kann durch entsprechende Variation der Mündungs- und Verzweigungsquerschnitte je nach Entfernung vom Wassereintritt und der Fließrichtung erreicht werden« Bei der Herstellung durch Extrusionsblasen können alle notwendigen Konturen und Geometrien bereits im Fertigungswerkzeug vorgesehen werden. Durch die bei modernen Extrusionsblasmaschinen mögliche gezielte Wanddickensteuerung können die Wanddicken der verschiedenen Kanäle des Heizkörpers gezielt reguliert werden.An even flow through all connecting channels can through corresponding variation of the mouth and branch cross-sections depending on the distance from the water inlet and the direction of flow, «During manufacture by Extrusion blow molding can have all the necessary contours and Geometries are already provided in the production tool. Due to the possible with modern extrusion blow molding machines Targeted wall thickness control, the wall thickness of the various channels of the radiator can be regulated in a targeted manner.
