Glass welded metal vacuum insulated panel with getter and production method thereof
The invention discloses a glass welded metal vacuum insulated panel with a getter. The metal vacuum insulated panel comprises a shell, a core material and a vacuum cavity, and is characterized in that the shell is made from either a low carbon steel plate or a low carbon steel composite plate, the core material is located in the vacuum cavity and is used for providing additional strength to the shell to ensure the smoothness of the shell at barometric pressure, and the vacuum cavity is a closed cavity formed by carrying out glass welding at normal pressure and high temperature and sealing at high pressure to the shell and the coefficients of thermal expansion of a low carbon steel plate and the glass solder are matched; the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, and a getter is arranged in the vacuum cavity. A production method of the metal vacuum insulated panel with the getter provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation and fire resistance can be improved.
