Thermopiles• Thermo-Electric Device• Converts Thermal Energy to Electrical
o Based on the Seebeck & Peltier Effects• Constructed from various Ceramics
o Ours are Bismuth Telluride
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
Efficiency- Experimental Determination
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
Requirements
• Measure Electrical Characteristicso Impedanceo Determine Power & Efficiency
• Measure Heat Transfer • Adjust Axial Loading• Display and Record Data• Test in Vacuum
Mechanical Systems- Loading
• DC Linear Actuator• Springs to Increase
Resolution• Load cell• Guide Rods• Load Isolation
o Heatero Cooler
