열전달 특성을 고려한 펠티어 냉방 장치의 핀 형상 최적화

Optimization of fin configuration in a cooling system using Peltier elements are investigated by changing the twist angle of fins and the relative distance between first and second row fins. A commercial software, CFD-ACE+,is utilized for the conjugate heat transfer problem that includes fins and base plates in the fluid-solid interface. Input parameters such as the cooling capacity of the Peltier elements and inlet air temperature are assumed to be given. The change of the exit temperature due to the change of fin configurations are numerically computed and compared with each other. It is found that twist angle is not a favourable factor for enhancing the heat transfer.
