Experimental study on satellite´s passive thermal-regulation units
 Mateášik, Timko Marek ; Mašek, Jakub (oponent) ; Lazar, Václav (vedoucí práce)
Master‘s thesis examines the eect of thermal interface materials on thermal contact conductance and resistance. The thesis focuses on application of the thermal interface materials for the thermal contact conductance enhancement in the miniaturised heat switch and the spacecraft generally. Theoretical part of this work briey reviews variety of passive thermal control systems used in spacecraft, including thermal interface materials and explains the background of this work. This work further a reviews of the variety of thermal interface materials, especially coatings and foils, and introduce the selection of suitable thermal interface materials. Experimental part of this work examines surface parameters, thermal conductivity and microhardness of copper specimens which serve as substrate for pure silver coating. Further examines the measurement conditions, evaluation methods and experimental measurements. The experimental measurements are carried out in thermo-vacuum test chamber and conclusion are made based on the results. The recommendations for further work are made.
