Embodiment 1
[0043] Embodiment 1: see figure 1 , the glass-welded double-vacuum-layer metal composite vacuum panel is composed of a panel 1, a connecting layer 2, a vacuum chamber 3, a support 4 and a partition 5, and the panel 1 is made of a thin metal such as a stainless steel plate or an aluminum alloy plate with a thickness of 0.2-1.5mm. board structure; the connecting layer 2 is a high temperature resistant adhesive, which can be selected from room temperature or high temperature cured high temperature resistant phenolic resin adhesive, epoxy resin adhesive, silicone resin adhesive and polyimide and other organic adhesives, as well as commonly used inorganic adhesives or organic adhesives. Inorganic composite adhesives, etc.; the vacuum chamber 3 is welded by low-carbon steel plates with a thickness of 0.3-1.0mm, and the same plate can be used for the partition 5, which is directly welded with the vacuum chamber 3, so that the vacuum chamber 3 forms two independent Vacuum layer; the s...
Embodiment 2
[0044] Example 2: See Example 1 and figure 2 , which is basically the same as in Example 1, except that the separator 5 is made of an aluminum alloy plate, which is directly placed in the vacuum chamber 3, and the low-carbon steel plate forming the vacuum chamber 3 is directly punched out of the support 4 and used for edge sealing during stamping and forming. The sealing groove is placed in the sealing groove, and the glass solder is placed in the sealing groove.
