摘要:
选择有机材料RT28HC作为相变蓄热材料,对等壁温(竖向)条件下矩形及楔形蓄热装置的热性能进行对比实验研究,包括蓄热过程典型时刻的相界面记录及多点温度的监测.结果显示:所述矩形及楔形装置均具有二维传热特性;与传统的矩形装置相比,楔形的几何形状可有效改善装置的竖向温度分布,消除装置底部的传热及融化死角,实现强化传热.热源温度越高时,楔形几何形状的强化传热效果越显著
Abstract:
An experimental study by contrast on melting performance of the rectangular and wedge-shaped thermal storage units was conducted. The organic RT28HC is employed as latent heat thermal energy storage material and melts in the unit heated from one vertical side. The solid-liquid interface distribution is recorded and temperature of multipoint is monitored during the melting process. Results show that both the rectangular and wedge-shaped unit show two-dimensional heat transfer characteristics. Compared with the traditional rectangular unit, there are significant improvements in the temperature distribution and melting process of wedge-shaped unit. The dead space of melting and heat transfer has been eliminated in this geometry, so the wedge-shaped unit can enhance the heat transfer of melting. Moreover, the higher the heat source temperature is the more significant is the heat transfer enhanced.
