摘要
介绍了一种低温肋板式蓄热器,并以石蜡(RT@80)作为蓄热材料,运用试验方法对自然对流对蓄热器性能的影响进行了研究,通过改变蓄热器的摆放方向及倾斜角度,测定蓄热器完成蓄热、放热的时间,结果表明: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;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。
A new type low-temperature Plate-fin thermal storage was presented, and the influence of natural convection for the characteristics of thermal storage was studied by through experiment with paraffin as regenerative material, the time of the heat storage and re- lease through changing the placement method and angle of thermal storage was measured, the results show that the natural convection exer- cises 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. Also, the influences on heat storage and release performance are different, which caused by natural convection for the different placement of thermal storage with the same angle.
