Abstract: In this study, a novel waste heat recycle power generation system is developed by using an integrated design to give higher power generation efficiency. The system consists of thermoelectric generator (TEGs), heat collecting sheets and absorbing layer. After the construction of the generator, the performance of the generator was experimentally evaluated. A collaborative enhancement of output power for TEG modules are obtained and the overall output power has been improved by the optimized design of the system. Based on the experiments, after heating 20 minutes, the temperature difference of TEG can reach 53℃, and the output voltage and current are 35V, 0.56A respectively. The total amount of generated power is enhanced to 20W. Furthermore, the prototyped of the waste heat recycle power generation system is relatively small and cheap. After the fabrication and testing of the prototype, this system has been proved feasible for practical application.

Keywords: Renewable energy, thermoelectric generator, waste heat, heat collector.
