Thermal contact resistance of planar surfaces
 Mateášik, Timko Marek ; Horák, Marek (oponent) ; Mašek, Jakub (vedoucí práce)
Bachelor‘s thesis examines the thermal contact resistance of planar surfaces for purposes of miniaturised heat switch project. The thesis focuses on nding of suitable mathematical model for prediction of thermal contact resistance as one of the possible solutions for miniaturized heat switch optimization. This work consists of theoretical and practical part. Theoretical part briey introduce a background of the project and the reason for initiation of this work. This work, further examines the denition of thermal contact resistance and factors that inuence it. Subsequently introduce a review of existing models for prediction of thermal contact resistance, appropriate selection of models for the possible use and their description. Practical part examines the copper specimens layout and manufacture for experimental measurements, their further modications and surface measurements. Further examines the measurement methods, measurement conditions and the experiments of thermal contact resistance. Theoretical measurements are carried out with the use of models from theoretical part and experimental measurements are carried out with the use of test chamber. Measurements are compared. Based on the results from measurements the conclusions are made, that will be used in the future for space component development.
