Modification of Aluminium Cooler Holder
Malovaný, Daniel ; Ramík, Pavel (referee) ; Svída, David (advisor)
The purpose of this thesis is to overview the basic design solutions of full aluminum radiators. By finite element method to check the first generation of full aluminum low temperature radiator bracket and based on this calculation to modify the design to reduce tension in the critical areas. At the end of this thesis to evaluate the new design.

Simulation of heat dissipation for power component
Sedlář, Tomáš ; Macháň, Ladislav (referee) ; Čožík, Ondřej (advisor)
The diploma thesis deals with the simulation of heat dissipation for LED Seoul SZ5-P. The heat transfer is discussed first. Further, the issue of thermal management and its design is analyzed. The dependence of LED junction temperature on area of single and double layer printed circuit board is simulated with Ansys Icepak. Additionally, influences of the number and placement of vias on the printed circuit board and aluminum substrate printed circuit board are simulated. Last but not least, the equations describing the dependence of printed circuit board area on desired LED junction temperature are derived. Finally, the values of heat transfer coefficient including convection and radiation are determined for various heat losses and junction temperatures.

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.

Active cooling of the car headlight
Žlebek, Jan ; Mauder, Tomáš (referee) ; Štětina, Josef (advisor)
The main goal of this bachelor thesis is to design the cooling of the headlamp by using a Peltier module. The first chapter is to acquaint the reader with the possibility of heat transfer. Further work is focused on various types of heatsinks and printed circuit board. The third part describes the principle of functions of Peltier's module. The last part of the work contains the design of the heatsink assembly and the design solution of fixing the cooling assembly in the housing.

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.

Airconditioning of sports centre
Vacková, Tereza ; Tesař, Zdeněk (referee) ; Rubina, Aleš (advisor)
The aim of the present bachelor thesis is to design air-conditioning devices in specific sections of a sports centre. The individual devices are designed to meet the hygienic, operational and functional requirements as demanded by the indoor microclimate of the premises. Devices 1 and 2 ensure the indoor air circulation, coverage of heat loss in winter and heat rise in sum-mer. Device 3 serves as a hot air ventilator for the hygienic facilities. The theoretical part of the thesis focuses on the issue of coolers. The practical part comprises of a proposal of three specific air-conditioning devices operating in a restaurant, squash courts and hygienic facilities. The result of the thesis is a project documentation of two air-conditioning devices for the given premises.
