Development and studies of switching heat-transfer joints of a thermoelectric generator and collector packages of a thermionic converter
Аннотация
Data from methodological development works that were intended for studying the thermal resistance and electric characteristics of the insulating layer of a multilayer metal-ceramic composite, which is used to produce switching heat-transfer joints of a cylindrical module of a thermoelectric generator and the collector packages of electrogenerating channels of a thermionic generator, are presented. The experimental results are presented of studies performed at the minimum value of the insulating-layer thickness (0.2 mm) of a metal-ceramic composite in the following system: SB1 alloy (Nb + 1% Zr)-Al2O3-SB1 alloy (Nb + 1% Zr), which is formed using the technique of plasma deposition of ceramics with subsequent gas-static pressing at high values of the inert-gas temperature and pressure in an autoclave.
