Abstract

Die Erfindung betrifft ein Wärmeübertragungsrohr, insbesondere Wärmerohr, bestehend aus einem dicht ver­ schlossenen rohrförmigen Körper, der innen mit einer längs-, schräg- oder querverlaufenden Feinprofilierung ver­ sehen ist und zum teil mit einem wärmeübertragenden Medium gefüllt ist. The invention relates to a heat transfer tube, especially heat pipe, consisting of a densely ver closed tubular body, the inside with a longitudinal, oblique or transverse fine profiling ver see and partly with a heat transfer Medium is filled.

Um ein Wärmeübertragungsrohr, insbesondere Wärme­ rohr, bestehend aus einem dicht verschlossenen rohrförmi­ gen Metallkörper zu schaffen, der innen mit einer längs-, schräg- oder querverlaufenden Feinprofilierung versehen ist und zum Teil mit einem wärmeübertragenden Material gefüllt ist zu schaffen, wird vorgeschlagen, daß der Körper aus einem profilierten Metallband (1) von geringer Wand­ stärke, d.h. 0,1 bis 0,6 mm, insbesondere bis ca. 1 mm hergestellt ist, wobei das Metallband wendelförmig zu einem Rohr (13) gewickelt und an den Kanten verschweißt oder verklebt ist, die Profilierung des Metallbandes im Querschnitt gewindeprofilartig ausgebildet ist und im wesentlichen die ganze Wandung erfaßt, wobei die Innenprofilierung in gleicher oder abgeschwächter Weise außen abgebildet ist. To a heat transfer pipe, especially heat tube, consisting of a tightly sealed tubular to create a metal body, the inside with a longitudinal, oblique or transverse fine profiling is provided and partly with a heat transfer material is filled to create, it is suggested that the body from a profiled metal band (1) from a small wall strength, i.e. 0.1 to 0.6 mm, in particular up to approx. 1 mm is made, the metal strip being helical Tube (13) wrapped and welded on the edges or is glued, the profiling of the metal strip in cross section is designed like a thread profile and essentially the whole wall detected, the inner profile in is depicted in the same or weakened manner on the outside.
