Applications of thermoelectric generators
Kopřiva, Lukáš ; Pospíšil, Jiří (referee) ; Brázdil, Marian (advisor)
This bachalor thesis is about thermoelectric generators and their utilization. Basic physical principles of thermoelectric conversion and design of thermoelectric devices are described at the beginning. Next part of thesis is related to practical applications of themoelectric generators. Applications that using fossil fuels, waste heat and renewable energy are mentioned. Conclusions and evaluations of their usefulness are made at the end.

Applications of thermoelectric generators
Kováč, Samuel ; Konečná, Eva (referee) ; Máša, Vítězslav (advisor)
The work describes the principle of thermoelectric conversion and the phenomenons by which it is mediated, it also deals with the factors that need to be sought in an effort to achieve the best efficiency of thermoelectric conversion. The next part includes an overview of case studies that serve as inspiration for the last, main part of this work, which will deal with the design of thermoelectric generator (TEG) integration. In this work found the procedure of selection of individual components that are not be excluded for the proper functioning of the thermoelectric generator. While the testing is performed on the basis of a mathematical model.It should confirm or refute the implementation of this project. Today, there is an electrical circuit including a thermoelectric generator, a DC converter, and wireless network sensors. The mathematical model confirmed that the TEG would be able to power -pressure, humidity and temperature sensors, at current of 0.314 A. The assumed temperature difference is 70 ° C. The work should acquaint the reader with the main pitfalls of thermoelectric conversion. It could also serve as a support in solving a similar problem of TEG implementation in a particular application.

Possibilities of waste heat recovery from internal combustion engines
Křivák, Petr ; Pospíšil, Jiří (referee) ; Brázdil, Marian (advisor)
Increasing demands for vehicular traffic to reduce the environmental impact and consumption of fossil fuels, led an effort to increase the efficiency of the combustion process and the car as a whole. One way to achieve this is to use the waste heat of the combustion process, especially waste heat of exhaust gases. This heat can be converted into electrical energy. Consumption of electricity in modern cars is increasing. The presented work deals with the possibilities, how to using waste heat of exhaustgases from internal combustion engine. Focused on application of producing electricity. The paper analyzed the current state of car traffic, and then provides an overview of possible technological solutions using waste heat of exhaust gases. The main part is devoted to thermoelectric generators, their construction and possible design. In conclusion is made the energy balance with use thermoelectric generator.
