Glass welded metal composite vacuum plate welded with mounting hole and production method thereof
The invention discloses a glass welded metal composite vacuum plate welded with a mounting hole. The glass welded metal composite vacuum plate comprises a panel, a connecting layer and a vacuum cavity, and is characterized in that the mounting hole and an extraction opening are combined, the mounting hole penetrates through the entire composite plate, the panel and/or the connecting layer are used for providing additional strength to the vacuum cavity to ensure the smoothness of the vacuum cavity at barometric pressure, and the vacuum cavity is a closed cavity formed by carrying out glass welding at constant temperature and high temperature and sealing at constant pressure to a low carbon steel plate; the sealing is that an extraction opening preformed in the vacuum cavity is automatically sealed by a low temperature solder in a vacuum furnace according to a liquid sealing theory, and a support is arranged in the vacuum cavity. A production method of the glass welded metal composite vacuum plate provided by the invention is simple in process, the defects of an existing insulation board and an existing vacuum insulated panel can be overcome, and the strength, heat insulation, sound insulation and fire resistance can be improved.
