Glass welded metal vacuum insulated panel and production method thereof
The invention provides a glass welded metal vacuum insulated panel. The glass welded 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 low carbon steel plates or low carbon steel composite plates, the core material is located in the vacuum cavity formed by hermetically welding the shell and is used for providing the additional strength to the shell to ensure the smoothness of the shell at barometric pressure; the vacuum cavity is a sealed cavity formed by welding and sealing a glass solder at high vacuum and high temperature and the coefficients of thermal expansion of the low carbon steel plate and the glass solder are matched. A production method of the glass welded metal vacuum insulated panel provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, the air-tightness of the vacuum cavity of the metal vacuum composite plate can be effectively ensured, the service life of the metal vacuum composite plate can be prolonged, and the strength, heat insulation, sound insulation, fire resistance and decorative function can be enhanced.
