Abstract
Transient behavior of thermoelectric cooling with a semiconductor thermocouple is studied experimentally and compared with the theoretical calculations, taking into account the initial temperature distributions in the thermocouple elements and the effect of heat exchange with the sorrounding atmosphere at the surface.
In the present work, theoretical analyses and numerical calculations of the response of Peltier cooling at the cold junction are made on the assumption that a factor of heat exchange with th surrounding media including the atmosphere depends on the ratio of the heat transfer coefficient of the surface to the thermal conductivity of the elements under various conditions concerning the above factor and the DC current pulse applied. The above analyses are, except for the temperature near dew-point, in fairly good agreement with the experimental facts of thermoelectric cooling with (Sb2Te3-Bi2 Te3)-(Bi2Te3-Bi2Se3) compound semiconductors in atmosphere.
