Heat transfer enhancement for PCM-based heat storage with plate fins

25 Oct 2015-

TL;DR: In this paper, the melting process in a phase change material (PCM)-based heat sink with plate fin type thermal conductivity enhancers is numerically studied. And the results showed that decreasing the pitch of fin fin resulted in an appreciable increase in overall thermal performance.

Abstract: The low thermal conductivity of phase change material (PCM) is the main resistance of heat transfer in latent storage system. Characterization of melting process in a PCM-based heat sink with plate fin type thermal conductivity enhancers is numerically studied in this paper. Detailed parametric investigations of plate fins are performed to find the effect on melting time. The results showed that decreasing the pitch of fins resulted in an appreciable increase in overall thermal performance. Increasing the fin thickness and conductivity only gave a slight improvement.

Abstract: The present paper is the first comprehensive review of the integration of phase change materials in building walls. Many considerations are discussed in this paper including physical considerations about building envelope and phase change material, phase change material integration and thermophysical property measurements and various experimental and numerical studies concerning the integration. Even if the integrated phase change material have a good potential for reducing energy demand, further investigations are needed to really assess their use.
