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 Q dot_in = q" in * A Q dot_out = q" out * A From 1st Law: Q dot_in - P out = Q dot_out Where P out = V 2 / R Nu=P out / Q dot_in

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

Design Mechanical Systems Thermal Systems Electrical Systems Software

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