Flexible structure development for efficient heat transfer
Černoch, Jakub ; Lazar, Václav (oponent) ; Mašek, Jakub (vedoucí práce)
The master’s thesis deals with theoretical calculations and design of a structure for heat transfer, which is part of a Miniaturized Heat Switch according to the specified requirements of the European Space Agency. The basic parameters are low weight and high thermal conductivity. The work follows the switch designed by Arescosmo, which did not meet the requirements, especially in the area of weight and thermal conductivity. Using theoretical calculations of weight and thermal conductivity, 49 variants were verified in 3 basic concepts – Mechanical contact structure, flexible structure composed of wires and foil structure. In terms of thermal conductivity, the best structures are those based on the use of metal stocking and sleeving braids. Manufacturing technologies have also been proposed from available sources that could be used to produce these structures. To meet the requirements, in the next phase of the project it will be necessary to produce experimental samples on which the theoretical calculations and selected technologies will be verified.

Conceptual design of a heat switch installation into a structure of satellite
Vrba, Martin ; Horák, Marek (oponent) ; Mašek, Jakub (vedoucí práce)
This Master thesis focuses on compiling a construction and heat-paths overview of space ships and space vehicles, which are used currently. Based on specific requirements and standards, conceptual designs are developed for the inclusion of a thermal switch into the satellite structure. In these chapters, specific parts are described, which partake on the heat conduction and are important from the construction view for these designed concepts. This Master thesis describes methods of computation of thermal conductivities and distribution of the force of gravity to the points of attachment for individual concepts. At the end, an evaluation and selection of the potential optimal concept is done.
