| Abstract Scope |
We report on the performance of solid-state thermoelectric (TE) devices based on Distributed Transport Properties (DTP) material systems. Supported by NSF and AFWERX Phase I SBIR grants, we have developed a single-stage DTP thermoelectric module capable of achieving a 210 K cold-side temperature with a 300 K hot-side temperature. This development is advancing toward commercialization as the DTP-90 module. Building on this progress, our ongoing work targets the development of a two-stage DTP-130 device designed to achieve a 170 K cold-side temperature at a 300 K hot-side temperature, meeting key AFWERX objectives. We present updates on both programs, including experimental performance results and validated modeling predictions. Modeling indicates the potential for up to a 10X improvement in coefficient of performance (COP) and heat pumping capacity at high temperature differentials. We further project how these advances enable a path to achieving a 100 K temperature differential in a single-stage device. |
