Thermoelectric conversion module and vehicle including the same
A thermoelectric conversion module may include a plurality of n type thermoelectric conversion materials and a plurality of p type thermoelectric conversion materials that are disposed alternately, and a plurality of electrodes that connects the plurality of thermoelectric conversion material disposed alternately on one side and on an opposite side alternately, wherein the plurality of electrodes includes a first electrode configured to electrically connect the n type thermoelectric conversion material and the p type thermoelectric conversion material by penetrating the n type thermoelectric conversion material and the p type thermoelectric conversion material to transfer heat obtained from a heat source to the plurality of thermoelectric conversion materials.
1. A thermoelectric conversion module comprising:
a plurality of n type thermoelectric conversion materials and a plurality of p type thermoelectric conversion materials that are disposed alternately; and
a plurality of electrodes configured to connect the plurality of thermoelectric conversion materials disposed alternately at low temperature side end portions and a central portion of the plurality of thermoelectric conversion materials alternately, and
wherein the plurality of electrodes includes:
a first electrode configured to penetrate a central portion of an n type thermoelectric conversion material and a central portion of a p type thermoelectric conversion material that are adjacent to each other to form a radial thermal gradient in the plurality of thermoelectric conversion materials by transferring heat obtained from a heat source to the plurality of thermoelectric conversion materials, and
wherein the first electrode is further configured to protrude towards a pipe, through which a heat transfer fluid flows, with respect to high temperature side end portions of the plurality of thermoelectric conversion materials such that the first electrode is inserted into a through-hole formed at the pipe to obtain the heat while directly contacting with the heat transfer fluid and to transfer the obtained heat to the plurality of thermoelectric conversion materials.
2. A vehicle comprising:
a thermoelectric conversion module disposed in an exhaust pipe, through which exhaust gas flows, to generate electric power by use of heat of the exhaust gas,
