摘要：
In order to improve the heat storage performance of latent heat storage unit (LHSU), three novel heat transfer tubes of the LHSUs were proposed, including frustum, wavy, and frustum wavy heat transfer tube LHSUs. Based on the numerical simulation, the heat storage performance of the cylindrical heat transfer tube latent heat storage unit (C-LHSU) and the above three novel LHSUs were compared. In addition, the influence of the tilt angle of the heat transfer tube on heat storage performance was studied for the LHSU with the frustum wavy tube (FW-LHSU). The results showed that the three novel tube structures could enhance heat storage performance, and the FW-LHSU had the optimal heat storage performance. Compared with C-LHSU, FW-LHSU had a 32.64% reduction in melting time and a 48.1% enhancement in heat storage density. The heat storage performance of FW-LHSU could be further improved by increasing the tilt angle of the heat transfer tube. When the tilt angle of the heat transfer tube increased from 2° to 8°, the heat storage time of FW-LHSU decreased by 37.00%, and the heat storage density increased by 48.44%, respectively. © 2024 Chemical Industry Press Co., Ltd..
