Examples
Example Embodiment
[0043] Example 1
[0044] Example 1 of Table 1 is an example in which the thickness t of the vacuum insulation panel 12 is set to 5 mm, and the flow thickness T of the rigid polyurethane foam 11 is set to 10 mm (T=2t). In this Example 1, when the rigid polyurethane foam 11 is foamed, no unfilled voids are generated near the corresponding part, and the thermal conductivity is 18.7 mW / m·K, and the central part is subtracted from the overall density. The numerical value of the density is 3.2, and the rigid polyurethane foam 11 itself has a numerical value that is not very different from that of Conventional Example 1. This can be considered that the flow of the rigid polyurethane foam 11 progresses smoothly, and the inherent physical properties of the rigid polyurethane foam 11 are obtained.
Example Embodiment
[0045] Example 2
[0046] Example 2 of Table 1 is an example in which the thickness t of the vacuum insulation panel 12 is set to 5 mm, and the flow thickness T of the rigid polyurethane foam 11 is set to 15 mm (T>2t). In this example 2, when the rigid polyurethane foam 11 is foamed, no unfilled voids are generated near the corresponding part, and the thermal conductivity is 18.5mW / m·K, and the central part is subtracted from the overall density. The value of the density is 3.4, which is not much different from the conventional example 1. It can be considered that the flow of the rigid polyurethane foam 11 progresses smoothly, and the material properties inherent in the actual rigid polyurethane foam 11 are obtained.

[0049] Example 3
[0050] Example 3 of Table 1 is an example in which the thickness t of the vacuum insulation panel 12 is set to 10 mm, and the flow thickness T of the rigid polyurethane foam 11 is set to 20 mm (T=2t). In this Example 3, when the rigid polyurethane foam 11 is foamed, no unfilled voids are generated near the corresponding part, and the thermal conductivity is 18.6mW / m·K, and the central part is subtracted from the overall density. The value of the density is 3.5, and the rigid polyurethane foam 11 itself has a value that is not very different from that of Conventional Example 1. This can be considered that the flow of the rigid polyurethane foam 11 progresses smoothly, and the inherent physical properties of the rigid polyurethane foam 11 are obtained.
