摘要

针对多孔吸附材料普遍导热性能较差的问题，利用金属和含碳材料的高热导性改善磷酸铝导热性能，将铜粉（Cu）、铝粉（Al）金属颗粒和纳米石墨烯片（GNPs）以10%、20%、30%这3种不同质量分数加入SFO型磷酸铝（AlPO-SFO）中，研究不同质量分数的各类高导热材料对磷酸铝吸附制冷性能的影响以及复合吸附剂的导热特性。实验结果表明：纳米石墨烯片是SFO型磷酸铝吸附剂最有效的热添加剂，添加质量分数为30%的GNPs可使吸附量降低37%，导热系数提高216%。

Abstract

As one method to improve the poor thermal conductivity of porous adsorption materials

metals and carbon-containing materials with high thermal conductivity are utilized in the adsorbent aluminum phosphate. Copper powder

aluminum powder metal particles

and graphene nanoplatelets (GNPs) were added to SFO aluminum phosphate (AlPO-SFO) in three different mass fractions (10%

20%

and 30%). The effects of these different high-thermal-conductivity materials with different mass fractions on the adsorption and refrigeration performances of aluminum phosphate and thermal conductivity characteristics of the composite adsorbents were studied. The experimental results showed that the GNPs were the most effective thermal additives for the SFO aluminum phosphate adsorbents. Adding mass fractions of 30% GNPs reduced the adsorption capacity by 37% and increased the thermal conductivity by 216%.
