Abstract

A heat pipe comprising an evaporator incorporating a porous medium with an oblique portion extending from the adiabatic region, in order to increase the capillary pumping and boiling limits. The invention relates to a heat pipe (1) extending along a first longitudinal direction (X), comprising a sealed enclosure (2) delimited by at least one peripheral wall (10), containing a working fluid and extending between a first longitudinal end (3), intended to be heated by a hot source SC to form, within the enclosure, an evaporator (ZE), and a second longitudinal end (4) intended to be cooled by a cold source SF to form, within the enclosure. According to the invention, the evaporator is designed by incorporating a porous medium (15) shaped to allow the vapor phase of the working fluid from the heat pipe to return to the adiabatic region through an oblique portion without interfering with the liquid phase saturating said medium.Figure for the abridged version: Fig. 8.
