The object is achieved in that the molded channels are arranged in the plane of the heat exchanger plate and the material rests formschlüssessig by the beginning of the channel gap material doubling at half the channel circumference.
Description
Die Erfindung betrifft eine Wärmetauscherplatte als Teil für einen flächigen, luftbeaufschlagten Wärmetauscher, vorzugsweise für Kühl-und Gefriermöbel.The invention relates to a heat exchanger plate as part of a flat, luftbeaufschlagten heat exchanger, preferably for refrigerators and freezers.
Wärmetauscher sollen sich, um einen optimalen Wärmeaustausch zu ermöglichen, durch einen guten Wärmeübergang zwischen den beiden Austauschmedien auszeichnen.Heat exchangers should be characterized by a good heat transfer between the two exchange media in order to allow optimal heat exchange.
Bekannt sind mit DD-WP 236162 Wärmetauscher, bestehend aus einer medienführenden Rohrleitung und einem die Oberfläche vergrößerndem Leitblech, wobei das Leitblech Verformungen aufweist, die einen möglichst guten Kontakt zur Rohrleitung ermöglichen sollen.Known are DD-WP 236162 heat exchanger, consisting of a media-carrying pipe and a surface enlarging guide plate, the guide plate has deformations that should allow the best possible contact with the pipeline.
Die DE-OS 3109853 beschreibt eine Wärmetauscherplatte, in welche Kanäle eingeformt sind, die mittels geeigneter Verfahren verschlossen werden. Diese Ausführung bietet gegenüber der vorgenannten Lösung außer der Möglichkeit der Materialeinsparung der medienführenden Rohrleitung den Vorteil eines günstigeren Wärmeüberganges. — Nachteilig auf die Stabilität und den Raumbedarf der Wärmetauscherplatte wirkt sich der Abstand der eingeformten Kanäle von der Plattenebene aus und erschwert die Komplettierung mehrerer Wärmetauscherplatten zu großflächigen Wärmetauschern.DE-OS 3109853 describes a heat exchanger plate in which channels are formed, which are closed by suitable methods. This embodiment offers over the aforementioned solution except the possibility of saving material of the media-carrying pipeline the advantage of a cheaper heat transfer. - The disadvantage of the stability and the space requirement of the heat exchanger plate, the distance of the molded channels affects from the plate level and complicates the completion of several heat exchanger plates to large heat exchangers.
Einen weiteren Nachteil dieser Lösung stellt die Anordnung und Form des Spaltes der geformten Kanäle dar, da bei Einsatz effektiver werkstoffschmelzender Verbindungsverfahren für den Verschluß der Kanäle eine Materialdickenreduzierung nur in begrenztem Maße möglich ist.Another disadvantage of this solution is the arrangement and shape of the gap of the formed channels, since the use of effective material melting connection methods for the closure of the channels, a material thickness reduction is only possible to a limited extent.
Ziel der Erfindung ist es, eine Wärmetauscherplatte zu schaffen, die einen minimalen Materialeinsatz ermöglicht und für den Einbau einen geringen Platzbedarf hat.The aim of the invention is to provide a heat exchanger plate, which allows a minimal use of material and has a small footprint for installation.
Die Erfindung stellt sich die Aufgabe, eine Wärmetauscherplatte zu entwickeln, die in vorteilhafter Weise die Vorzüge bekannter Lösungen zur Verbesserung des Wärmeüberganges nutzt, günstigere Bedingungen für den Verschluß der Längsnaht am geformten Kanal schafft und die Stabilität der Wärmetauscherplatte für die Komplettierung mehrerer Platten erhöht. Erfindungsgemäß wird die Aufgabe dadurch gelöst, daß die Achse der in bekannter Weise in eine einstückige Wärmetauscherplatte eingeformten zylindrischen Kanäle in der Ebene des flächigen Wärmetauschers verläuft, wobei das Material der Wärmetauscherplatte durch die am Kanalspalt beginnende Materialdoppelung formschlüssig am halben Kanalumfang anliegt.The invention has as its object to develop a heat exchanger plate, which advantageously takes advantage of known solutions to improve the heat transfer, creates more favorable conditions for the closure of the longitudinal seam on the molded channel and increases the stability of the heat exchanger plate for the completion of multiple plates. According to the invention the object is achieved in that the axis of the molded in a known manner in a one-piece heat exchanger plate cylindrical channels in the plane of the planar heat exchanger, wherein the material of the heat exchanger plate rests positively by the beginning of the channel gap material doubling at half the channel circumference.
Durch die Lage der Kanäle in der Ebene der Wärmetauscherplatte wird der Platzbedarf des Wärmetauschers verringert. Die zwangsläufig eintretende Materialdoppelung erhöht in vorteilhafterweise die Stabilität der Platte für einen segmentartigen Aufbau eines Wärmetauschers, schafft darüber hinaus die Voraussetzung, die Materialdicke bei metallschmelzenden Verbindungsverfahren für den Verschluß des Kanalspaltes gering zu halten und gewährleistet durch diese Anordnung eine pro Flächeninhalt der Wärmetauscherplatte verbesserte Wärmeableitung.Due to the position of the channels in the plane of the heat exchanger plate, the space requirement of the heat exchanger is reduced. The inevitably occurring material doubling advantageously increases the stability of the plate for a segment-like construction of a heat exchanger, also creates the prerequisite to keep the material thickness low in metal-melting connection method for the closure of the channel gap and ensured by this arrangement a per area of the heat exchanger plate improved heat dissipation.
Die Erfindung soll nachstehend an einem Ausführungsbeispiel erläutert werden. Die zugehörigen Zeichnungen zeigen:The invention will be explained below using an exemplary embodiment. The accompanying drawings show:

, Durch die Verformung des Materials der Wärmetauscherplatte 1, wie in o.g. Figuren dargestellt, wird der zylindrische Kanal 2 unmittelbar in der Ebene 4 der Wärmetauscherplatte 1 angeordnet. Der innige formschlüssige Kontakt im Bereich der Materialdoppelung 5 gewährleistet einen guten Wärmeübergang und schafft durch die Materialverstärkung am Kanalspalt 3 günstige Voraussetzungen für das Verschweißen oder Verlöten desselben., By the deformation of the material of the heat exchanger plate 1, as in o.g. Figures shown, the cylindrical channel 2 is arranged directly in the plane 4 of the heat exchanger plate 1. The intimate positive contact in the material doubling 5 ensures good heat transfer and creates by the material reinforcement at the channel gap 3 favorable conditions for welding or soldering the same.
