VACUUM INSULATION PANEL, AND APPARATUS AND METHOD FOR EVALUATING INTERNAL VACUUM LEVEL OF THE VACUUM INSULATION PANEL USING FREQUENCY RESPONSE METHOD

摘要

PURPOSE: A vacuum insulation panel and an apparatus for evaluating the inner vacuum degree of the vacuum insulation panel using a frequency-response method are provided to disperse or reduce impact force depending on the surface flatness and hardness of the vacuum insulation panel. CONSTITUTION: A vacuum insulation panel(100) comprises an exterior material(110), a core material(120), and a rigid body(130). A getter, which is harder than reference strength, is inserted between the exterior material and the core material and maintains the surface flatness and hardness of the vacuum insulation panel. The rigid body is formed on the top of the getter.
