Heat exchanger equipped with thermal electric device for engine exhaust carbon dioxide collection system

摘要

An electricity generating heat exchanger (18) for a vehicle (12) equipped with an exhaust gas (16) carbon dioxide (CO2) separator, said heat exchanger (18) comprising:
an exhaust gas chamber (50) configured to guide engine (14) exhaust through the heat exchanger (18);
an absorber fluid chamber (52) configured to guide CO2 absorbent fluid (24) through the heat exchanger (18); and
a first thermal electric generator (TEG (54)) configured to couple thermally the exhaust gas chamber (50) to the absorber fluid chamber (52) in a manner effective to heat the CO2 absorbent fluid (24) by heat from the engine (14) exhaust to release CO2 gas from the CO2 absorbent fluid (24) and generate electricity in response to a temperature difference therebetween.
