摘要

Planar structure having a predetermined thickness and a first surface (3) and a second surface (5) suitable for the transportation of heat energy, wherein the flat structure (1) at least one hollow fiber (6), a length which is a multiple of the thickness of the structure (1) and the course of which corresponds to the inside of the structure (1), in many cases, between the first surface (3) and the second surface (5) changes, characterized in that the hollow fiber (6) a tightly closed hollow space (9) forms, the partially with a vaporizable working fluid (10) is filled, wherein the on or at the first surface (3) extending portion of the hollow fiber (6) a condensation region (25) and the on or at the second surface (5) extending portion of the hollow fiber (6) a evaporation region (24) for these working fluid (10) forms.
