Abstract:
PURPOSE: A manufacturing apparatus of a microparticle for heat control material is provided to coat a microbead phase transition material with a boron nitride particle with excellent thermal conductivity, thereby facilitating generation of phase transition. CONSTITUTION: A manufacturing apparatus of a microparticle for heat control material comprises a melt bath melting phase transition material; an ultrasonic high temperature vibrator for sonicating the melted phase transition material to form mist; a glass pipe in which carriers transferring the phase transition material are injected; and a collecting container in a trapping chamber which is located in the upper part of the glass pipe, to form microparticle solidified through the glass pipe.

Abstract:
PURPOSE: A battery case of a pouch cell is provided to improve heat-radiant property by maximizing a contact area with air by using two kinds of heat-radiant composite material which has excellent insulation and lightweight. CONSTITUTION: A battery case of a pouch cell comprises a main body part(10) which accepts an electrode assembly for battery and has a plurality of heat-radiant protrusions on the surface, and a cap part covering the both ends of the main body part. The main body part comprises a connector(12), which consists of a film type box structure which has an opening on both sides, frame parts(11) which maintains rigidity by being positioned on both edge parts of the connection part. The cap part additionally comprises a flow channel groove formed on the inner side of the bottom, and cools heat generated from a electrode part in an electrode assembly by air which flows along the flow channel groove.
