Three Stage Micro Cooler,
Abstract
To determine the properties, in particular the thermophysical properties, of various materials in a wide range of temperatures, local sources of cooling are necessary with smooth regulation of temperature. To carry out investigations at temperatures with a lower limit of -80 to 90C, thermoelectric cooling systems are useful, for example, a three-stage thermoelectric device. In the laboratory of semiconducting cooling of the Odessa Technological Institute of the Food and Refrigeration Industry, a three-stage microcooler was developed and tested. The cooler has crystalline semiconducting materials of the following composition: p-type-75 mol-% Sb2 Te3 + 25 mol.% Bi2 Te3 + 4 percent by weight Te + 1 percent by weight Se; n-type-90 Mol-% Bi2 Te3 + 10 Mol.% Bi2 Se3 +0.13 percent by weight Hg2 Cl2. These crystals were grown by the Bridgeman-Stokbarger method.
