Special Issue Information

Dear Colleagues,

With the development of technology and industry, the issue of energy consumption has become increasingly serious. The recovery and utilization of waste-heat energy have attracted increasing attention from multiple fields. Semiconductor thermoelectric generator technology is a new type of power generation technology, and its use in waste-heat energy recovery and utilization can improve energy efficiency. The working principle of a semiconductor thermoelectric generator is based on three basic concepts: the Seebeck, Peltier, and Thomson effects. Compared with other power generation methods, this process is noiseless and has no wear and medium leakage. In addition, the module has the advantages of small volume, light weight, convenient movement, and long service life. Thus, it is highly suitable for waste-heat energy recovery and utilization systems, especially for low-grade energy utilization. In this Special Issue, we aim to study the application and optimization of small-scale thermoelectric generators, as well as the combination and application of thermoelectric and cross-field technology.

This study investigates the thermal efficiency and exergy efficiency of a thermoelectric power generation device for recovering power cable surface waste heat. Numerical simulations are conducted to analyze the impact of different types of cooling fins on the system’s performance. The results demonstrate that the installation of cooling fins improves heat transfer efficiency and enhances the thermoelectric power generation device’s output power. Among the various fin designs, the system equipped with cooling fins with 17 teeth exhibits the highest performance. These findings highlight the importance of fin design in optimizing the system’s thermal efficiency and exergy efficiency. This study provides valuable insights for the development and improvement of thermoelectric power generation systems for power cable surface waste heat recovery applications. Full article
