Obstojnost protizmrzovalnih površin prenosnikov toplote

Kelher, Rok (author), Golobič, Iztok (mentor), Zupančič, Matevž (co-mentor)

Protizmrzovalne površine so površine, ki preprečujejo nastajanje ledu. V delu so predstavljene protizmrzovalne površine, ki se uporabljajo pri prenosnikih toplote in metode njihove izdelave. Analizirana je obstojnost različnih superhidrofobnih površin glede na postopek njihove izdelave. Ovrednoteni sta mehanska in kemijska stabilnost superhidrofobnih površin skupaj s trenutnimi omejitvami uporabe in izdelave. Trenutna stopnja razvoja in izdelave še ne omogoča zadostne obstojnosti za pogosto uporabo v realnem življenju. Testi obstojnosti niso standardizirani in ne omogočajo enakovrednega testiranja.

• Title: Durability of anti-icing surfaces of heat exchangers

Abstract

Anti-icing surfaces are surfaces that prevent the formation of ice. The paper presents anti-icing surfaces used in heat exchangers and methods of their fabrication. The durability of different superhydrophobic surfaces according to the process of their fabrication is analyzed. The mechanical and chemical stability of superhydrophobic surfaces is evaluated together with the current limitations of use and fabrication. The current stage of development and manufacturing does not yet allow sufficient durability for frequent use in real life. Durability tests are not standardized and do not enable equivalent testing.
