Metal composite vacuum heat insulation plate with edge sealed by seal strip and manufacturing method thereof
A metal composite vacuum heat insulation 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 or a metal composite plate, the face plate and/or the connecting layer provide/provides additional strength for the vacuum cavity and ensure/ensures the smoothness of the vacuum cavity under atmospheric pressure, the vacuum cavity is a closed cavity formed by welding a low-carbon steel plate and sealing the edge by utilizing a glass solder under the constant pressure and high temperature and performing high-temperature sealing under the vacuum condition, the seal strip is arranged at the welding position of the edge portion of the low-carbon steel plate, the sealing is automatic sealing performed by utilizing an air exhaust opening pre-formed in the vacuum cavity and a low-temperature solder in a vacuum furnace according to a liquid seal principle, and a support is arranged in the vacuum cavity. A manufacturing method of the metal composite vacuum heat insulation plate is simple in process, the manufactured metal composite vacuum heat-insulation plate can overcome the shortcomings of existing heat preservation plates and vacuum heat-insulation plates, the air impermeability of the vacuum cavity of the metal composite vacuum heat-insulation plate can be effectively ensured, the service life of the metal composite vacuum heat-insulation plate can be prolonged, and strength and heat-insulation, sound-insulation and fireproof performance can be improved.
