  1. 1. Thermoelectric Generators : A comparison of electrical power outputs depending on temperature.

    Kandidat-uppsats, Högskolan Dalarna/Institutionen för information och teknik

    Författare :Erik Fransson; Daniel Olsson; [2021]
    Nyckelord :Waste heat; thermoelectric generator; thermoelectric cooler; Seebeck effect.;

    Sammanfattning : Today many processes generate a lot of waste heat, for example industries or cars. One way to make this thermal energy useful is to transform it into electrical energy with a thermoelectric generator (TEG) or thermoelectric cooler (TEC). This technology is not used in any large scale today, but a lot of research is being done on the subject. LÄS MER

  3. 2. Thermoelectric Cooler Prototype Based on Bismuth Telluride and Aimed for Space Applications

    Uppsats för yrkesexamina på avancerad nivå, Uppsala universitet/Tillämpad materialvetenskap

    Författare :Viktor Karlsson; [2017]
    Nyckelord :Thermoelectric cooler; bismuth telluride;

    Sammanfattning : The main goal for this project was to design, manufacture and evaluate a thermoelectric cooler, TEC, prototype. One of the biggest challenges with TECs is that they need to be very reliable and have a long lifetime. LÄS MER

  4. 3. How to handle boil-off gases from LNG trucks

    Master-uppsats, Linköpings universitet/Maskinkonstruktion; Linköpings universitet/Tekniska fakulteten

    Författare :Linda Gunnarsson; Erik Helander; [2015]
    Nyckelord :LNG; Liquefied natural gas; boil-off; boil-off gases; BOG; natural gas;

    Sammanfattning : This master thesis project aims to investigate the circumstances of boil-off for heavy vehicle transports, using LNG as fuel, and suggest possible ways of handling these gases otherwise released into the atmosphere. LNG, Liquefied Natural Gas, is when natural gas is cooled below its vaporisation point, turning it into liquid phase which is a much more dense way of storing and transporting the fuel. LÄS MER

  5. 4. Optimization of the Electric Properties of Thermoelectric Generators

    Uppsats för yrkesexamina på avancerad nivå, Lunds universitet/Institutionen för reglerteknik

    Författare :Adham Shawwaf; [2010]
    Nyckelord :Technology and Engineering;

    Sammanfattning : The efficiency in an internal combustion engine ranges from 25% to 45%. About 50% - 85% of the overall energy losses in a combustion engine is heat which is either cooled away by the vehicle's radiator or blown out with the exhaust gases. LÄS MER
