Abstract

Abstract

Microencapsulated Phase Change Material (MEPCM) suspension liquid is a coolant with high heat capacity,which can enhance considerably liquid cooling performance.MEPCM with a double-layered shell containing paraffin and melamine resin as wall material was prepared.Its surface condition and thermal characteristics were obtained through SEM and DSC respectively.The spherical shape particles were observed to be well-wrapped by using optical microscope and Scanning Electronic Microscope (SEM).The influence of different parameters in terms of radius distribution and encapsulation properties on the characteristics of the MEPCM has been investigated.Very high heat sink capacity of the MEPCM was found by DSC method.
