2, Descriptions

  Pure PCMs of our SL-PCMs have high density of latent heat storage capability, and with wide range melting temperature for various application, they are using extensive in the thermal energy management.However, the pure PCMS have the disadvantage of low thermal conductivity under the circumstance without no additive or encapsulated in specific space,they have insufficiently performance in the usage when rigorous requirement on high thermal conductivity effectiveness.

  How to achieve and enhance efficiently the thermal conductivity rate then? The solution by modulation of thermal conductivity through various methods can increase the rate of charging and discharging heat, resulting in a higher efficiency of thermal energy storage systems. The ways of enhancing thermal conductivity are divided into two typical types:

• Adding substances with high thermal conductivity

• Encapsulated phase change materials

3, Enhancement of Thermal conductivity

  Following Figure concluded the method and process how to enhance a PCMs thermal conductivity,the most promising is the carbon based material for example the expanded graphite inserted to our Pure organic phase change material which composite to our high thermal conductivity thermal PCMs.
