纳米复合相变材料传热特性研究

通过在低导热的相变材料中加入高导热纳米颗粒来增强相变材料的固有导热性能，研究纳米颗粒种类、含量和分散剂对纳米增强型复合相变材料（NePCMs）传热过程的影响，并获取本数据集。该数据集包含了不同浓度和纳米颗粒种类的NePCMs的热物性参数测试曲线，不同条件（添加物种类、添加物浓度、分散剂）下NePCMs的升温曲线。通过数据对比和计算，可以得出导热系数与黏度随纳米添加剂浓度的变化关系、最佳纳米添加物种类及分散剂种类。

This dataset is developed by adding high-thermal-conductivity nanoparticles into low-thermal-conductivity phase change materials (PCMs) to enhance the intrinsic thermal conductivity of PCMs, and investigating the effects of nanoparticle type, content and dispersant on the heat transfer process of nano-enhanced phase change materials (NePCMs). The dataset includes thermophysical property test curves of NePCMs with different nanoparticle concentrations and types, and temperature rise curves of NePCMs under various conditions including additive type, additive concentration and dispersant. Through data comparison and calculation, the variation relationships between thermal conductivity, viscosity and nanoparticle additive concentration, as well as the optimal nanoparticle additive type and dispersant type, can be derived.
