Abstract
A novel-structure vacuum insulated panel is composed of a blocking bag 1, glass cotton felt 2, a metal foil material 3 and a getter 4, and the vacuum insulated panel extremely low in heat conductivity coefficient and long in service life is formed after vacuum treatment and heat treatment are conducted. The initial heat conductivity coefficient of the vacuum insulated panel is as low as 1.5-2.5 mw, and the elevated value is smaller than 1.0 mw after twenty-seven days of 80 DEG C-65% RH high-temperature and high-humidity life test. Meanwhile, compared with a vacuum insulated panel of a traditional structure, the novel-structure vacuum insulated panel is low in heat bridge effect and excellent in energy conservation effect.
