Thermoelectric Field Analysis of Trapezoidal Thermoelectric Generator Based on the Explicit Analytical Solution of Annular Thermoelectric Generator

The geometrical configuration is one of the main factors that affect thermoelectric performance a device. Research on trapezoidal generator (TTEG) with varied cross section mainly based finite element simulation and experiment. In this paper, an explicit analytical solution maximum output power annular generators (ATEG) proposed, which has been proved to have high accuracy. Then, between ATEG TTEG compared. Results show that, for appropriate geometric parameter δ, relative error simulated can reach order 10−3. When hot end at side, temperature θ 510 K 10°, respectively. For Bi2Te3 material PbTe material, 0.0261% 0.074%, Under suitable working conditions, results provide some reference optimization TTEG.
