Cryogenic thermoelectric properties of BiTe-based alloys and cryo-energy power generation
Year: 2010
Type: article
Abstract: The BiTe-based alloys were fabricated by mechanical alloying and cold-pressing sintering. Seebeck coefficient and electrical conductivity were measured at the temperature range of 80—300 K. Results showed that the thermoelectric properities of the materials were excellent during the experiments. With the thermoelectric conversion device made of BiTe-based alloys, a new cryo-energy utilization equipment were established. By applying liquid nitrogen in the experiments, the cryo-energy was released during evaporation of liquid nitrogen, and then, a study of electric properties of thermoelectric conversion devices was further deployed. The relationship of output voltage and output power versue current intensity was obtained from the experiments. The maximum output power in the experiments was up to 1.33 W,which verified the feasibility of cryo-energy power generation.
