Heat transfer in the pressure cover of the GFR reactor
Koryčanský, Roman ; Suk, Ladislav (referee) ; Martinec, Jiří (advisor)
This paper describes the design of the ventilation pressure cover of the demonstrator GFR. The first part is a brief research project GFR and the effects of temperature on the inside structures. In the following part is calculated balance heat losses within the pressure cover for three cases: non-insulated, fully-insulated and partially insulated surface of the reactor. The following is a design of a heat sink for partially insulated surface.

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.

The Design of Formula Student Brake Disc
Novosad, Pavel ; Hejtmánek, Petr (referee) ; Blaťák, Ondřej (advisor)
This bachelor thesis deals with Formula Student vehicle Electric Dragon 2 brake disc desings. Proposed designs underwent thermal and stress analysis based on relevant literature. The main criterion is keeping the disc temperature in the optimal operating window for brake pads while reducing weight. Durability of the discs is set to one racing season. Final design is compared to the previous one used in older generations of the vehicle.
