Double-vacuum-layer composite vacuum plate with edge sealed by seal strip and manufacturing method thereof
A double-vacuum-layer composite vacuum plate sealed by a seal strip comprises a face plate, a core plate and a vacuum cavity and is characterized in that the face plate is fixed to the upper surface outside the vacuum cavity in a welding or bonding mode, the core plate is arranged at the bottom of the inside of the vacuum cavity, the vacuum cavity is formed by welding a thin low-carbon steel plate, the face plate and/or the core plate provide/provides additional strength for the vacuum cavity, the vacuum cavity is welded and sealed by utilizing a glass solder in a vacuum furnace under the high vacuum and high temperature, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the low-carbon steel plate is matched with the coefficient of thermal expansion of the glass solder, a partition plate is arranged in the vacuum cavity and divides the vacuum cavity into two to form double vacuum layers, and supports are arranged in the vacuum layers. A manufacturing method of the double-vacuum-layer composite vacuum plate is simple in process, and strength, heat-insulation, sound-insulation and fireproof performance and a decorative function can be improved.
