Metal vacuum composite panel with sealing strips and mounting holes and manufacturing method thereof
A metal vacuum composite panel with sealing strips and mounting holes comprises a housing, at least two core plates and a vacuum chamber and is characterized in that the mounting holes are combined with pumping holes and penetrate through the whole composite plate, the housing is a low-carbon steel plate, the core plate is arranged in the vacuum chamber to provide the housing with additional strength, 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 opening sealing is the automatic sealing of the pumping holes preformed in the housing with low-temperature solder in a vacuum furnace according to the principle of liquid seal, the low-temperature solder comprises low-temperature metal and alloy solder, and supporting members are arranged between the core plates. A manufacturing method of the metal vacuum composite panel with the sealing strips and the mounting holes is simple in process. The manufactured metal vacuum composite panel with the mounting holes can overcome the deficiencies of existing insulation boards and vacuum insulation panels and the strength and thermal insulation, sound insulation and fireproof performance can be improved.
