Abstract
Diplomová práce se zabývá ověřením funkčnosti prototypu zařízení, které bylo realizováno ve spolupráci s ČVUT FEL. Toto zařízení využívá elektromagnetického záření o frekvenci 2,45 GHz a bylo zkonstruováno za účelem ohřevu plošných útvarů, zvláště pak textilních materiálů. Úvodní část práce se zabývá rozborem teorie elektromagnetického pole a procesu sušení. Dále byla vypracována technologická příručka - seznam doporučení pro obsluhu zařízení. Následně byly realizovány experimenty. Bylo změřeno vyzařování soustavy do okolí a zmapována tepelná pole materiálu po ohřevu. Dále byly zjištěny sušící křivky textilních materiálů a byl simulován jejich posun. Okrajově byla také vyzkoušena možnost využití zařízení pro finální úpravy textilií. V závěrečné části byly experimenty vyhodnoceny a navrženy možnosti konstrukčních zlepšení prototypu zařízení.
The objective of this diploma thesis is to verify the functionality of the prototype, which was constructed in cooperation with CVUT FEL. This machine uses an electromagnetic field at the frequency of 2,45GHz and was designed for heating planar objects, especially textile materials. The first section analyzes the theory of the electromagnetic field and the process of drying. Furthermore, a guide handbook was written with a list of recommendations on how to use this prototype. The following section describes the execution of the experiments. After the heating of the materials, the measurements of the machine emissions to the outside were taken and thermic fields of the materials were mapped. Additionally, the drying curves were taken and their movement was simulated. Further, the possibility of using the machine for final adjustments of textiles was also tested. In the final section, the experiments were evaluated, and design changes were suggested to improve the prototype.
