Transcript of "Eem ppt"

  1. 1. ELECTRICAL AND ELECTRONIC MATERIALS
  2. 2. PRESENTED TO :- Mr. Arvind Gupta sir
  3. 3. Thermoelectric Generators
  4. 4. IntroductionThermoelectric Generators ( also called thermo-generators) are devices which convert heat (temperature differences) directly into electrical energy, using a phenomenon called the "See-beck effect" (or "thermoelectric effect").Their typical efficiencies are around 5-10%.
  5. 5. Radio-isotope thermoelectricpower generator
  6. 6. Internal Glance
  7. 7. Micro power Module
  8. 8.  Older See-beck-based devices used bimetallic junctions and were bulky while more recent devices use bismuth telluride (Bi2Te3) semiconductor p-n junctions and can have thicknesses in the millimeter range.These are solid state devices and unlike dynamos have no moving parts, with the occasional exception of a fan.Radioisotope thermoelectric generators can provide electric power for spacecraft. Automotive thermoelectric generators are proposed to recover usable energy from automobile waste heat.
  9. 9. U S E S :-
  10. 10. thermoelectric generators are used for :- Small applications where heat engines such asStirling engines would not be possible. The use of waste heat in combustionengines promises to be a high volumeapplication field. Not only the exhaust butalso cooling agents are targeted.
  11. 11. To increase the efficiency a of the combinedsolar/thermoelectric system and convert thesolar radiation into useful electricity.Thermoelectric modules can be used for energyrecovery of otherwise wasted heat.Several companies have begun projects ininstalling large quantities of these thermoelectricdevices.
