Abstract
This study investigates the performance of a thermophotovoltaic (TPV) system utilizing liquid cooling to achieve the overall power output of 10W. TPV technology converts thermal energy into electricity using radiation emitted from high-temperature sources. In contrast to traditional photovoltaic systems, TPV systems integrate additional components like filters to optimize energy absorption by the TPV cells, thereby increasing conversion efficiency. Numerical simulations using ANSYS 2024 software is developed to analyze the impact of air-fuel equivalence ratios in a porous medium on the required combustion temperature to optimize system performance. The three-dimensional design of the TPV power system is realized using SolidWorks 2022, focusing on the interaction between TPV cells and the liquid cooling system. Results demonstrate that liquid cooling, particularly with a solid-liquid interface, significantly enhances the efficiency of converting thermal energy to electrical energy. The study encompasses analysis of thermal performance during porous media combustion and evaluates the radiation received by TPV cells. Results indicate that the optimal equivalence ratio, particularly at 1.20 in lean mixtures, yields the highest combustion temperature necessary for achieving a maximum power output of 7455.4 W from TPV cells. Comparison between air and liquid cooling systems reveals that liquid cooling with a solid-liquid interface offers superior cooling performance, thereby enhancing overall system reliability and efficiency. These insights provide valuable contributions to the advancement and refinement of TPV systems, particularly in applications requiring efficient and reliable cooling solutions
