新型肋板式相变蓄热器蓄热和放热性能试验研究

摘要

通过改变蓄热器的摆放方向和倾斜角度测定蓄热器完成蓄热、放热时间的方法,研究了自然对流对蓄热器性能的影响.试验结果表明:①随着倾斜角度的增加,自然对流对蓄热器蓄、放热速率的影响逐渐增加,使得蓄热器的蓄、放热时间逐渐缩短.②相同的倾斜角度下,不同的摆放方式对蓄热器性能的影响不同.%This article had applied the methods of experimental study to the influence of influence of natural convection on thermal storage, the time of the heat storage and release through changing the placement method and angle of thermal storage was measured, the results show that,① the natural convection exercises greater and greater influences on the heat storage and release performance of thermal storage as the angle of thermal storage increase, which caused the heat storage and release rate of thermal storage becomes faster and faster. ②The influences on heat storage and release performance were different, which were caused by natural convection for the different placement of thermal storage with the same angle.
