摘要:
针对相变蓄热应用于散热器供暖存在的问题,开展以石蜡为相变蓄热基体,以膨胀石墨为强化传热载体的复合相变蓄热材料性能的实验研究.制备石蜡/膨胀石墨复合相变材料时,以相变温度64 ℃的石蜡为基体,加入膨胀石墨强化传热性能.实验研究表明:质量分数为3.0%的50目膨胀石墨蠕虫可以有效提高材料热导率;在相变蓄热水箱中,加入质量分数为3.0%的50目膨胀石墨蠕虫后,相变材料蓄放热时间缩短了50%;质量分数为3.0%的50目膨胀石墨试样的相变潜热值为203.1 J·g-1.
Abstract:
Aiming at the problem of phase change thermal storage applied to radiator heating, the experimental research on the performance of composite phase change thermal storage material with paraffin as phase change thermal storage matrix and expanded graphite as heat transfer carrier was studied. When preparing the paraffin/expanded graphite composite phase change material, paraffin having a phase transition temperature of 64 ℃ was used as a matrix, and the expanded graphite was added to enhance the heat transfer performance. Experimental tests show that the addition of 50 mesh expanded graphite worms with a mass fraction of 3.0% can improve the thermal conductivity of the material effectively; and in the phase change hot water tank, the heat storage time of the phase change material shortens by 50% after adding these expanded graphite worms; the latent heat value of the 50 mesh expanded graphite sample with a mass content of 3.0% is 203.1 J·g-1.
