Abwärmerückgewinnung in Personenwagen durch thermoelektrische Module

Due to rising fuel prices, shortage of oil resources and growing environmental awareness, the issue of energy efficiency of passenger cars is becoming increasingly important. In addition to efforts to optimize the efficiency of the internal engine, the use of the enormous waste heat losses seems to make sense. So far, only a small part of the thermal energy not converted by the engine is used (heating, turbocharger, catalytic converter, etc.). Thermoelectrics offers an approach to better use of waste heat, which has recently been the subject of renewed research at increased expense. With the help of so-called thermoelectric generators, the direct conversion of thermal energy into electrical energy is possible. Within the scope of this work, a prototype was developed which provides for the integration of a thermoelectric generator into the silencer of the exhaust tract. With regard to exhaust gas system.
