Short-Circuited Thermoelement in Cooling Mode

Abstract

Results of computer simulation research on the short-circuited thermoelement (SCTE) with slanted shorting in cooling mode are presented. The distribution of physical fields in the thermoelement was obtained, enabling determination of the basic energy parameters of the SCTE for different numbers of shorting conductors, cross-sectional area, and orientation relative to the temperature gradient. The SCTE design was optimized to achieve maximum temperature difference and cooling capacity.

Theoretical investigation of permeable segmented generator thermoelement on the base of Bi-Te, Pb-Te, Si-Ge

“…Due to the presence of heat exchange between heat carrier and "cold" parts of legs it allows to give more thermal energy to material and convert it into electric energy. Computer calculations of such permeable models of thermoelements [7,8] confirmed the possibility of improving the efficiency of energy conversion by 30%.…”

“…Based on the obtained relationships with the use of successive approximation technique, the Runge-Kutt numerical method for solving a system of differential equations ( 1) and (7) with the boundary conditions ( 3) and ( 8), the Newton method for solving systems of integrallydifferential equations ( 6), ( 9), (10), a computer program was design of permeable segmented thermoelement was developed. The results of computer study of thermoelement are given below.…”
