Description

Die Erfindung bezieht sich auf ein Wärmeleitrohr mit Kapillarkanälen entsprechend dem Oberbegriff des Patentanspruchs 1.The invention relates to a heat pipe with capillary channels according to the preamble of Claim 1.

Bei einem bekannten Wärmeleitrohr dieser Art (DE-AS 15 01 505) ist ein einstückiger metallischer Grundkörper vorgesehen, der Kapillarkanäle in der Außenfläche und quer dazu verlaufende Ausnehmungen in der Innenfläche aufweist Der Herstellungsaufwand ist hierbei beachtlich.In a known heat pipe of this type (DE-AS 15 01 505) is a one-piece metallic Basic body provided, the capillary channels in the outer surface and recesses running transversely thereto in the inner surface. The manufacturing expense is considerable here.

Ferner ist es bekannt, bei Wärmerohren, Metallwhisker oder feine Drahtgeflechte, die eng an der Innenwand des Rohres anliegen, einzubringen (DE-AS 27 968). Diese Einlagen wirken im fertigen Wärmerohr als Kapillarsysteme.It is also known to work closely with heat pipes, metal whiskers or fine wire meshes Make contact with the inner wall of the pipe (DE-AS 27 968). These deposits work in the finished heat pipe as capillary systems.

Darüber hinaus ist bekannt, Wärmeleitrohre an ihrer Innenwand mit schraubenförmig in das Rohr eingebrachten Kapillarkanälen (DE-AS 25 52 679) zu verse-In addition, it is known that heat conduction tubes are screwed into the tube on their inner wall Capillary channels (DE-AS 25 52 679) to verse

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 ein besonders günstiger Wärmeaustausch ermöglicht istThe 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 what is specified in the characterizing part of claim 1 Characteristics.

Bei der Herstellung eines erfindungsgemäßen Doppelwandrohres kann von einem Band ausgegangen werden, in dem für das Außenrohr Rillen eingebracht sind und in dem Innenrohr Ausnehmungen, 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 Ausnehmungen sind dabei vorzugsweise im Bereich der Verdampfungs- und Kondensationszone vorgesehen.A tape can be used as the starting point for the manufacture of a double-walled pipe according to the invention be, in which grooves are made for the outer tube and recesses in the inner tube, for. B. by Punching out, are arranged. Both bands are piped together in such a way that the profiled band the outer tube with the longitudinally profiled inside and the recessed band form the inner tube. The recesses are preferably 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 Kapillarkanäle und damit den konstanten Eigenschaften des Wärmeleitrohres. Gegenüber Wärmsleitrohren mit offenen Kapillaren wird ein höherer Wirkungsgrad erzielt.The advantages of this double pipe lie in the simple quantity production, the separation in useful lengths, in the controlled, reducible arrangement of the capillary channels and thus the constant ones Properties of the heat pipe. Compared to heat pipes a higher degree of efficiency is achieved with open capillaries.
