UA84218C2 - Sectional thermoelectric generator using organic fuel - Google Patents

Abstract

The invention relates to thermoelectric means for conversion of heat energy resulting from organic fuel burning to electrical one. A sectional thermoelectric generator with a heat source using organic fuel comprises thermoelectric modules located between hot and cold radiators of every section. A first radiator’s section is heated by hot inlet gases come in directly from the heat source, a second section is heated by gases came in from the first section. Heat exchangers of the hot radiator of the first section comprises from one side fins and channels for hot gases passing, which are united with the corresponding fins and channels of second section hot radiators; from the other side – heat-contact planes with two-stage thermoelectric modules in the first section and one-stage thermoelectric modules in the second section, which have a heat contact with liquid heat-exchangers for rejection of heat from modules. The invention provides increase in efficiency of thermoelectric generators using organic fuel.
