VACUUM INSULATOR WITH REDUCED EFFECTIVE THERMAL CONDUCTIVITY COEFFICIENT AND A FILLER FOR THE SAME

摘要

PURPOSE: A vacuum insulator and a filler for the same are provided to minimize the heat transfer through lattice structures in the vacuum insulator by filling a porous filler in the lattice structures.;CONSTITUTION: A vacuum insulator comprises first and second lattice structures(100,200), a porous filler, and first and second plates(300a,300b). The first and second lattice structures are arranged in parallel and comprise upper and lower beams(120,220,110,210) and pillar beams(130,230) vertically connecting the corners of the lattice structures. The porous filler is filled in the spaces formed by the lattice structures. The first and second plates are arranged on the exterior of the first and second lattice structures. The second lattice structure is attached to the upper side of the first lattice structure so that the pillar beams of the second lattice structure are arranged across those of the first lattice structure.;COPYRIGHT KIPO 2011
