[0055] Example 1

[0056] The first glass layer 1, the second glass layer 2 and the diaphragm 3 are all curved structures, the thickness of the first glass layer 1 and the second glass layer 2 are both 5 mm, wherein the first layer of glass is Low-e glass, the thickness of the diaphragm 3 is 0.1 mm, the diaphragm 3 is a single-curvature diaphragm 3, and the diaphragm 3 is not provided with a low-radiation reflective film, a skeleton structure is provided on one side of the diaphragm 3, the skeleton structure includes rods 6 arranged at intervals, the rods 6 have a diameter of 0.5 mm, the rods 6 are made of transparent material, and the interval between two adjacent rods 6 is 50 mm; the spacer 4 is 12 mm thick, and the curved cavity is filled with argon gas.

[0057] Example 2

[0058] The first glass layer 1, the second glass layer 2 and the diaphragm 3 are all curved structures, the thickness of the first glass layer 1 and the second glass layer 2 are both 6 mm, wherein the first layer of glass is Low-e glass, the thickness of the diaphragm 3 is 1 mm, the diaphragm 3 is a hyperbolic diaphragm 3, and the diaphragm 3 is not provided with a low-radiation reflective film, a skeleton structure is provided on one side of the diaphragm 3, the skeleton structure includes rods 6 arranged at intervals, the diameter of the rods 6 is 2.0 mm, the rods 6 are made of transparent material, and the interval between two adjacent rods 6 is 400 mm; the thickness of the spacer 4 is 12 mm, and the curved cavity is filled with argon gas.

[0059] Example 3

[0060] The first glass layer 1, the second glass layer 2 and the diaphragm 3 are all curved structures, the thickness of the first glass layer 1 and the second glass layer 2 are both 6 mm, wherein the first layer of glass is Low-e glass, the thickness of the diaphragm 3 is 0.5 mm, the diaphragm 3 is a hyperbolic diaphragm 3, the diaphragm 3 is provided with a low-radiation reflective film, a skeleton structure is provided on one side of the diaphragm 3, the skeleton structure includes rods 6 arranged at intervals, the rods 6 have a diameter of 1.0 mm, the rods 6 are made of transparent material, and the interval between two adjacent rods 6 is 200 mm; the spacer 4 is 12 mm thick, and the curved cavity is filled with argon gas.

[0061] Comparative Example 1:

[0062] The third glass layer is used to replace the diaphragm 3. The first glass layer 1, the third glass layer and the second glass layer 2 are arranged in sequence and are all curved structures. The thickness of the first glass layer 1, the second glass layer 2 and the third glass layer is 5 mm.

[0063] Comparative Example 2

[0065] Table 1 Comparison of insulating glass performance

[0066]

[0067] From the comparative example 2 in the table, it can be seen that when using two-glass one-cavity double white glass insulating glass, the glass heat transfer coefficient (U value) is relatively large. The larger the heat transfer coefficient, the less conducive it is to glass thermal insulation. Therefore, two-glass one-cavity insulating glass is basically not used at present, and three-glass two-cavity glass is generally used.

[0068] Examples 1-3 and Comparative Example 1 are all three-glass two-chamber insulating glass. Among them, both Examples and Comparative Example 2 use a layer of Low-e glass, and the glass thickness is 5mm. The heat transfer coefficient is basically similar, but the thickness and weight of Example 1 are significantly lower than those of Comparative Example 2; even if the thickness of the outermost two sides of the glass is increased to 6mm as in Example 2, the overall thickness and weight of the glass are still lower than those of Comparative Example 2; Example 3 is based on Example 2, and the middle diaphragm is also coated with a low-reflection film, which can further significantly reduce the heat transfer coefficient. Compared with Comparative Example 1, the heat transfer coefficient is reduced while reducing the glass thickness and weight.

[0069] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
