Micro particle for thermal control material and device and method of producing the same using ultrasonic high-temperature vibration scheme

摘要

Disclosed is a micro particle for a thermal control material capable of being applied as a highly thermal conductive material for thermal control, and an apparatus and a method of producing the micro particle for the thermal control material by using an ultrasonic high-temperature vibration scheme. More specifically, a Boron Nitride (BN) particle having a plate shape and an excellent thermal conductivity is coated on a PCM having a shape of a micro bead, to increase the thermal conduction to the inside PCM, so that a phase change is easily generated, and which allows an easy treatment of the PCM in a liquid state at a temperature equal to or higher than a melting point of the PCM.

1. A method of producing a micro particle for a thermal control material using an ultrasonic high-temperature vibration scheme, the method comprising:
melting a PCM; sonicating the melted PCM with a vibration frequency of at least 3 MHz to generate a misted PCM micro particle; solidifying the PCM micro particle through a heat treatment; collecting a solidified PCM micro particle; micro pulverizing Boron Nitride (BN) in a micro unit for coating on a surface of the solidified PCM micro particle; providing a functionality to the micro pulverized plate-shape BN; and coating the surface of the solidified PCM micro particle with a BN micro particle.
