摘要：
In order to improve the phase change energy storage effect in cube heat storage units，the melting effect of phase change materials after inserting fins was studied by numerical methods，and the influence of increasing the number of fins and changing the insertion position of fins on the melting rate of PCM was compared. The results show that the melting rate of PCM is significantly improved after the fins are inserted. Compared with the three-fin structure，the performance of single-fin and dual-fin energy storage units is improved with the increase of LR，f. The dual-fin energy storage unit with 0.75 LR，f of cube heat storage unit has better performance，and the PCM melting time is improved 193% compared with the non-fin structure. The downward shift of fins is helpful to shorten the PCM melting time，and 0.54HR，f structure has a better effect on PCM melting. © 2023 Science Press. All rights reserved.
