Description of water cooling of the PerformX spectrometer
Hudák, Pavol ; Himr, Daniel (referee) ; Fialová, Simona (advisor)
Bachelor thesis focuses on description of hydraulic components and values of water-cooling system, which is a part of the XRF spectrometer and its performance options. It includes research of some spectrometric analyses used in laboratories, including XRF spectrometry, along with advantages and disadvantages of these analyses. This is followed by research that focuses on fluid flow and its hydraulic losses. It includes division of water-cooling systems and describes in detail the water-cooling system of the XRF spectrometer. Furthermore, the thesis includes a measurement of pressure losses, coolant flow rate and progress of temperatures in the water-cooling system during operation of the device. Based on measured values, processes in the cooling systems have been described and schemes with values have been created. Weak points of the cooling systems were revealed, and possible optimizations of the water-cooling system was suggested.

Design of cooling of electrical machines for production machines and systems
Vaněrková, Tereza ; Vlach, Radek (referee) ; Huzlík, Rostislav (advisor)
The aim of this thesis is to design the water-cooling system for a synchronous motor with an output of 10kW. The power loss was analytically determinated. For the initial water-cooling system and for two design proposals, thermal models were calculated in Ansys. The same boundary conditions were set for all three models. Then the analysis results of the temperature distribution on the machine surface and in the slots were compared. The comparison also includes the economical cost of the production and service of the machine. Then the production documentation was created, consisting of the assembly drawings and a simplified technological process.
