Razvoj naprave za testiranje stenja

Žlebnik, Klemen (author), Golobič, Iztok (mentor)

Izdelali smo zasnovo merilne proge za testiranje stenja. Stenj uporabljamo za prenos kapljevine iz kondenzatorja v uparjalni del toplotne cevi. Gonilna sila je kapilarni vlek. V nalogi sta predstavljeni idejni rešitvi naprave za testiranje stenja: prva je zasnovana kot steklena cev, zatesnjena s pokrovoma na obeh straneh, druga pa kot steklena posoda v večji stekleni posodi s standardnim pokrovom za priključke. Obe rešitvi dopuščata variacijo dolžine mrežnega stenja od 60 do 100 mm. Izdelali smo napravo za testiranje stenja ter izvedli preliminarne meritve kapilarnega vleka. Meritve volumna nabrane tekočine ter toplotnega toka prikazujejo obetavne rezultate eksperimentalnega dela na razviti napravi.

• Title: Development of a wick testing device

Abstract

We developed a design of a wick testing device. The wick is used to transfer liquid from the condenser to the evaporator of a heat pipe. The process is driven by the capillary effect. 2 conceptual solutions for a wick testing device are presented in this work: the first one is designed as a glass tube with lids on both sides, the other is designed as a glass vessel in another glass vessel with a standard cover. Both solutions allow the variation of mesh wick lengths from 60 to 100 mm. We created a wick testing device and conducted a preliminary capillary effect experiment. Measurements of the gathered water volume and heat flux show promising results of the experimental work on the developed device.
