Fin이 부착된 PCM 축열조의 효율성 분석

Abstract

Fig.1과 같이 PCM(Phase Change Material)蓄熱 system內의 熱傳達을 증가시킬 目的으로 PCM內에 얇은 금속 fin을 설치한 것을 model로 하여 善熱單位의 길이와 폭, fin 두께 및 벽면온도의 변화에 대한 效率的인 蓄熱條件을 熱力學 第一法則과 第二法則을 適用하여 提示하였다.

A thermal energy storage using a PCM with fins is shown in Fig.1. Fins are set up increase the heat transfer rate within a PCM. Effective storage contraints have been presented by applying the first and the second law of thermodynamics when various parameters, e.g., the length and width of the storage unit, the thickness of the fin, and the wall temperature, are changed.
