Metal vacuum composite panel with sealing strips and getter and manufacturing method thereof
A metal vacuum composite panel with sealing strips and a getter comprises a housing, at least two core plates and a vacuum chamber and is characterized in that the housing is a low-carbon steel plate, the core plate is arranged in the vacuum chamber to provide the housing with additional strength to ensure the smoothness of the housing at atmospheric pressure, the vacuum chamber is a closed chamber formed by the housing subjected to glass soldering edge sealing at atmospheric pressure and high temperature and high-temperature opening sealing in vacuum, welding portions of the edge of the low-carbon steel plate are provided with the sealing strips, the coefficient of thermal expansion of the low-carbon steel plate is matched with that of glass solder, the opening sealing is the automatic sealing of pumping holes preformed in the housing with low-temperature solder in a vacuum furnace according to the principle of liquid seal, the getter is arranged in the vacuum chamber, and supporting members are arranged between the core plates. A manufacturing method of the metal vacuum composite panel with the sealing strips and the getter is simple in process. The manufactured metal vacuum composite panel with the getter can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength, thermal insulation, sound insulation and fireproof performance and decorative functions can be improved.
