Thermopile Test Bench

This project aims to design and fabricate a test bench capable of accurately determining the efficiency and electrical performance of thermopiles when subjected to a temperature gradient. The test equipment must endure vacuum conditions, apply and adjust axial loads, and effectively display and record crucial data. It will incorporate mechanical, thermal, and electrical systems, including DC actuators, Peltier coolers, and LabVIEW for data acquisition. Our thermopiles, constructed from Bismuth Telluride, utilize the Seebeck and Peltier effects to convert thermal energy to electrical energy.

  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
