Abstract

The heat carrying tube has a capillary system on the tube inner wall. The tube (1) with the capillary system forms an outer tube. A second tube (3) is inserted in this and lies against the inner wall of the outer tube. The second tube has cut-outs (4) which are spaced over the tube circumference and the tube length or part tube length. The longitudinal grooves (2) of the capillary system has a like or a different geometry.

Description

Gegenstand der Erfindung ist ein Wärmeleitrohr mit Kapillarsystemen gemäß Patent ... (Patentanmeldung P 29 16 051.8).The invention relates to a heat pipe with capillary systems according to patent ... (patent application P 29 16 051.8).

Es sind Wärmerohre mit eingebrachten Rillen in verschiedener Form bekannt. So ist zum Beispiel in der genannten Anmeldung vorgeschlagen worden, in die Oberfläche eines Metallbandes Rillen in einem beliebigen Winkel zur Metallkante verlaufend in rechteckiger halbrunder, U-förmiger oder halbelliptischer Form einzuarbeiten, wobei die Rillentiefe, -breite und -abstand weniger als 0,5 mm betragen. There are known heat pipes with grooves in various forms. So is for example in the mentioned Application has been proposed to make grooves in the surface of a metal strip at any angle Metal edge running in a rectangular semicircular, U-shaped or semi-elliptical shape to be incorporated, with the The groove depth, width and spacing are less than 0.5 mm.

Es ist auch bekannt, bei Wärmerohren, Metallwhisker oder feine Drahtgeflechte, die eng an der Innenwand des Rohres anliegen, einzubringen DE-AS 24 27 968). Diese Einlagen wirken im fertigen Wärmerohr als Kapillarsystem.It is also known to work with heat pipes, metal whiskers, or fine wire mesh that tightly adheres to the inside wall of the pipe apply to bring in DE-AS 24 27 968). These deposits act as a capillary system in the finished heat pipe.

Es ist auch bekannt, Wärmerohre mit schraubenförmig in das Rohr eingebrachten Nuten (DE-AS 25 52 679 zu versehen. Auch Wärmerohre mit Kapillarstruktureinsätzen sind bekannt (DE-AS15 01 505).It is also known to provide heat pipes with grooves (DE-AS 25 52 679) that are introduced into the pipe in the shape of a screw. Heat pipes with capillary structure inserts are also known (DE-AS15 01 505).

Auch die Herstellung von Wärmerohren aus Bändern, die längsprofiliert sind, ist bekannt.The production of heat pipes from strips that are longitudinally profiled is also known.

Aufgabe der Erfindung ist es, ein doppelwandiges Wärmeleitrohr zu schaffen, mit dem eine besonders günstige Wärmeaustauschung ermöglicht wird.The object of the invention is to create a double-walled heat pipe with which a particularly favorable Heat exchange is made possible.

Gelöst wird diese Aufgabe erfindungsgemäß durch die im Kennzeichen des Patentanspruchs 1 angegebenen Merkmale.This object is achieved according to the invention by the features specified in the characterizing part of claim 1.

Bei der Herstellung eines erfindungsgemäßen Doppelwandrohres kann entweder von einem Band ausgegangen werden, in dem für das Außenrohr Rillen eingebracht sind und inIn the manufacture of a double-walled pipe according to the invention, either a band can be assumed, in which grooves are made for the outer tube and in

dem Innenrohr Aussparungen, z.B. durch Ausstanzen angeordnet sind. Beide Bänder werden derart miteinander verrohrt, daß das profilierte Band das Außenrohr mit längsprofilierter Innenseite und das ausgesparte Band das Innenrohr bildet. Die Aussparungen sind dabei im Bereich der Verdampfungs- und Kondensationszone vorgesehen.recesses are arranged in the inner tube, e.g. by punching. Both bands are piped together in such a way that that the profiled band is the outer tube with a longitudinally profiled inside and the recessed band is the inner tube forms. The recesses are provided in the area of the evaporation and condensation zone.

Die Vorteile dieses Doppelrohres liegen in der einfachen Mengenherstellung, dem Trennen in Gebrauchslängen ,in der kontrolliert reduzierbaren Anordnung der Rillen und damit den konstanten Eigenschaften des Wärmerohres. Gegenüber Wärmerohren mit offenen Kapillaren wird ein höherer Wirkungsgrad erzielt.The advantages of this double pipe lie in the simple quantity production, the separation into useful lengths, in the controlled, reducible arrangement of the grooves and thus the constant properties of the heat pipe. Opposite to Heat pipes with open capillaries achieve a higher degree of efficiency.

In den beigefügten Zeichnungen sind mögliche Ausführungsformen des profilierten und ausgesparten Bandes des geschweißten Doppelwandrohres dargestellt.In the accompanying drawings are possible embodiments of the profiled and recessed band of the welded Double wall pipe shown.
