Abstract Scope |
We provide an update on the performance and production of thermoelectric devices that utilize distributed transport property (DTP) thermoelectric technology. Initial DTP prototypes show increases in maximum temperature difference of 8-10K with 2-3X increases in Coefficient of Performance (COP) and heat pumping at a 70K temperature difference. The theory of DTP technology and performance measurement comparisons to present TE material systems will be summarized. Validated modeling predicts the potential of up to a 10X improvement in COP and heat pumping capacity at high temperature differences. We discuss the potential impact of additive manufacturing to the production of DTP elements with geometries and compositions closer to optimal to achieve the highest performance TE elements. We project how these advances combine to create a path towards achieving a maximum temperature differential of 100K in a single stage TE module. |
