펠티어 소자를 사용한 냉방장치에서 핀 배열이 열전달 특성에 미치는 영향 연구

Heat transfer characteristics of fin configurations in a cooling system using Peltier elements are investigated by change the twist angle and the relative distance between the first row 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. The cooling capacity of the Peltier elements and inlet air temperature are assumed to be fixed. The change of the exit temperature due to the change of fin configurations are numerically computed and compared with each other.
