A test setup for thermal cycling of thermoelectric modules
Preisler, Lukáš ; Kudela, Libor (referee) ; Brázdil, Marian (advisor)
The present work is focused on thermoelectric modules and testing modes. Failures of thermoelectric modules occur due to the cyclic thermal stress in real applications and their power parameters decrease. Hence an experimental study of thermoelectric modules was executed, which measured parameters of thermoelectric modules and thermal cycling testing methods. In the practical part of this document, the thermal cycling conditions of thermoelectric modules were set-based on the previously stated study. A bipolar-pulse load in range +3,0 V and 3,0 V was proposed alternating after 90 seconds. For comparison of the modules among producers 200 cycles will be made. According to the cycling conditions, construction adjustments of current laboratory testing platform are proposed. The current platform is currently set to measure parameters of thermoelectric modules and is not for cycling load testing.

Use of Peltier Elements for Temperature Cycling
Müller, Petr ; Starý, Jiří (referee) ; Šandera, Josef (advisor)
This project deals with the use of Peltier frames for thermal cycling in the implementation of rapid testing in the workplace for thermo-mechanical stress solder joints. Its base is describing the various parts of the workplace. Peltier effect is shown and Peltier cells are described, which is the base of the workplace. They are analyzed possible ways to control workplace and summarized their advantages and disadvantages. It was constructed and described the system entering temperature cycles with electronics indicating fault frame.
