Abstract
An experimental Peltier refrigerator utilizing thermoelements of annular configuration has been designed, constructed, and operated. The thermoelectric materials used are p‐ and n‐type Bi2Te3 with ρp=2×10−3 ohm‐cm, ep=180 μvolts/°C, ρn=8.5×10−4 ohm‐cm, and en=−150 μvolts/°C. The device has been operated under ``no‐load'' conditions over a range of power inputs and has exhibited a maximum ΔT of 49°C. A simple theory relating to the performance of Peltier thermocouples is derived. Experimental performance of the device is shown to agree with theoretical predictions within experimental error.This publication has 4 references indexed in Scilit:
