Double-vacuum-layer metal composite vacuum plate with edge sealed by seal strip and manufacturing method thereof
A double-vacuum-layer metal composite vacuum plate with the edge sealed by a seal strip comprises a face plate, a connecting layer and a vacuum cavity and is characterized in that the face plate is a metal plate, the connecting layer enables the face plate and the vacuum cavity to be connected to form a whole, the vacuum cavity is formed by welding a thin metal plate and 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 and are independently manufactured or are directly formed on the vacuum cavity or the partition plate. A manufacturing method of the double-vacuum-layer metal composite vacuum plate is simple in process, the manufactured double-vacuum-layer metal composite vacuum plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.
