20.500.12556/RUL-140059 Razvoj vsebnika ultratanke toplotne cevi Development of an ultrathin heat pipe container V zaključnem delu smo razvijali vsebnik ultratanke toplotne cevi debeline do 0,5 mm. Posebno pozornost smo namenili izdelavi učinkovite notranje površine vsebnika, ki smo jo izdelali z uporabo laserskega strukturiranja bakrene folije debeline 105 µm. Topografijo površin posameznih kapilarnih struktur smo pregledali z uporabo optičnega mikroskopa, intenziteto kapilarnega vleka pa z uporabo posebno izdelane merilne proge za merjenje hitrosti omočenja površine. Vsebnik ultratanke toplotne cevi smo zaprli s procesom laserskega varjenja. Mikrostrukture v obliki globokih in ozkih kanalov so se izkazale za učinkovito kapilarno strukturo notranje površine vsebnika ultratanke toplotne cevi. Final thesis focuses on the development of an ultrathin heat pipe container, used in heat pipes with width of less than 0,5 mm. Special attention was given to the development of an internal wick structure, which was made using laser structuring process of the copper foil with thickness of 105 μm. Surface topography of the wick structure was inspected using optical microscope, while wicking performance of the manufactured wicks was inspected with specially made setup measuring a speed of surface wettability. Container of the ultrathin heat pipe was sealed using process of laser welding. Microstructures in the shape of deep and narrow channels were proven to be efficient wick structures of the inner surface inside the ultrathin heat pipe container. toplotna cev ultratanka toplotna cev vsebnik lasersko strukturiranje heat pipe ultrathin heat pipe container laser structuring true false false [J.
