  1. 1 Thermopile Test Bench Team Thermopilers Adrian Aspinall, Paul Sowinski, David Eld, Michael Sotolongo,Tyler Merritt

  2. Thermopiles • Thermo-Electric Device • Converts Thermal Energy to Electrical • Based on the Seebeck & Peltier Effects • Constructed from various Ceramics • Ours are Bismuth Telluride

  3. Problem Statement • To design and fabricate test equipment to accurately and easily determine efficiency and electrical performance of thermopiles under an imposed temperature gradient. The device must withstand vacuum, apply axial load, and display and record relevant data

  4. Qdot_in = q"in * A Qdot_out = q"out * A From 1st Law: Qdot_in - Pout = Qdot_out Where  Pout = V2 / R Nu=Pout/ Qdot_in Efficiency- Experimental Determination

  5. Requirements • Measure Electrical Characteristics • Impedance • Determine Power & Efficiency • Measure Heat Transfer • Adjust Axial Loading • Display and Record Data • Test in Vacuum 

  6. Design • Mechanical Systems • Thermal Systems • Electrical Systems • Software

  7. Mechanical Systems- Loading • DC Linear Actuator • Springs to Increase Resolution • Load cell • Guide Rods • Load Isolation • Heater • Cooler
