Embodiment 1
[0029] Embodiment 1: see figure 1 , the glass-welded metal vacuum insulation panel consists of an outer shell 1 and a core material 2, the outer shell 1 is composed of a low-carbon steel plate with a thickness of 0.3-1.0mm; the core material 2 is glass fiber, pearl sand, perlite, vermiculite, airgel etc., the core material 1 is preferably dried, packed in a plastic bag, pre-vacuumized, and the like. The manufacturing method of the glass-welded metal vacuum insulation panel is as follows: first, two low-carbon steel plates with the same size and a thickness of 0.3 mm are cut to make the shell 1, and the two low-carbon steel plates are folded and formed by stamping; secondly, After drying pearl sand or perlite with a certain particle size in a continuous kiln, put it into a plastic bag and seal it after vacuuming to make it a core material with a small volume and a certain shape; Material 2 is put into the cavity of lower shell 1, and glass solder 3 is coated on the welding par...
Embodiment 2
[0030] Example 2: See Example 1 and figure 2 , is basically the same as Example 1, except that the low-carbon steel plate forming the shell 1 is directly stamped out a groove for edge sealing during stamping, and glass solder is placed in the groove.
