Heat transfer in modern automotive lights
Holec, Radek ; Klimeš, Lubomír (referee) ; Štětina, Josef (advisor)
The beginning of this thesis is dedicated to light in general and all different types of vehicle lightning, also deals with various types of light sources and specifically about LED where it describes the temperature change behaviour. Second part deals with heat transfer by conduction, convection, and radiation, it describes quantities and relationships needed for next capitols. In the penultimate part is described thermal management of headlights, therefore different options of cooling and causes of heat generation, and different types of PCBs that are used in automotive. In the last part is proposed the heatsink, which should be used for cooling LED chips of daytime running lights.

Optimization of air conditioning of the wellness sports center
Prchalová, Nikol ; Rubina, Aleš (referee) ; Blasinski, Petr (advisor)
The diploma thesis deals with microclimate of a pool hall. This is divided into three parts. The first part describes the theoretical aspects of the environment in swimming pools in general. The second part of the diploma thesis deals with the calculation of the course of specific moisture concentration during the day in the pool hall. Different humidity concentration curves are assessed based on different electable input parameters. Subsequently, suitable setting options are evaluated in order to achieve acceptable environment in the hall in terms of humidity and optimal operating costs. The last part relates to the experimental part. This examines the measurement of evaporation under different boundary conditions and the subsequent comparison with some calculation methods for the calculation of evaporation.

Calculation of thermal resistance of finned heatsink
Kyanka, Radim ; Huták, Petr (referee) ; Toman, Marek (advisor)
This bachelor's thesis is focused on the problem with analytical calculations needed to define thermal resistance of finned heat sinks. First it describes how temperature proceeds at different boundary conditions at fin tip. Than it describes different mechanisms of heat transfer, equlation of heat resistance especially of natural and forced convection. To verify the results there is comparison between analytical equlations written in Matlab program and measuring results.

Process control of a distillery
Sejkora, Martin ; Kopečný, Lukáš (referee) ; Veselý, Libor (advisor)
This master‘s thesis deals with the design of a control system for a distillation column. It deals with the issue of distillate production and acquaints the reader with the necessary knowledge that is necessary to understand the purpose of the work. The practical part of the work presents a specific distillation column, the means for its control and the method of implementation of the control system, then the visualization of the control system and the method of control. Part of the work is the evaluation of the results and benefits of the work.

Optimalizace procesu chlazení mléka =: Optimization of the milk cooling process /
Nejtek, Vlastimil
The dissertation deals with potential energetic saving in cow milk cooling. The theoretical part contains an information about cow milk and refrigeration systems for milk cooling. Measuring in laboratory conditions was performed with the aim to collect a sufficient quantity of measured data for the qualified application of flat-plate coolers in measuring under real operating conditions. The practical part measuring in real operating conditions was implement in a farm. The practical part examines milk cooling using milk flow-through plate coolers and from the values obtained it formulates conclusions and recommendations for practice.

Conceptual design of a heat switch installation into a structure of satellite
Vrba, Martin ; Horák, Marek (referee) ; Mašek, Jakub (advisor)
Tato diplomová práce je zaměřena na sestavení přehledu konstrukcí a teplených cest kosmických lodí a kosmických vozidel, které se v současné době používají. Na základě specifických požadavků a standardů jsou vypracovány koncepční návrhy zástavby tepelného spínače do konstrukce družice. V jednotlivých kapitolách jsou popsány určité členy, které se na vedení tepla podílí a jsou důležité pro navrhované koncepty z pohledu konstrukce. Diplomová práce popisuje postupy výpočtu tepelných vodivostí a rozložení působící tíhové síly do míst uchycení pro jednotlivé koncepty. Na závěr provádí hodnocení a výběr potenciálně nejvhodnějšího návrhu.

Step down convertor
Koutný, Martin ; Kadlec, Josef (referee) ; Cipín, Radoslav (advisor)
Thesis deals with the evaluation of the solutions and the design of the DC voltage converters. The first describes the different types of converters, which subsequently choose types of resources for the construction. In other chapters of the work devoted to the design of schemes, selected types of sources and selection of circuits and components therefor, for the manufacture, including calculations cooling performance parts. The last chapter is devoted to the description of the structure and measurement of the produced sources. The measurements are primarily deals with the verification of the specified parameters.
