    • A core panel or box of rigid plastics microporous foam is provided with parallel spaced passages or thin grooves and is placed within an envelope or bag of flexible multi-layer barrier film impervious to the passage of gas. The bag includes an integral evacuation tubular portion which is releasably coupled to an evacuation nozzle connected by a manifold with solenoid valves to a vacuum pump. After air is substantially evacuated from the foam core and the bag to collapse the bag against the foam core and into the grooves, a vacuum sensor operates a computer which controls the valves for checking the vacuum level within the bag and for optionally admitting an additive gas. Closely spaced grooves within opposite sides of the foam panel provide for bending the evacuated panel, and a thin layer of foam is applied to the outer surface of the vacuum insulated panel to provide a protective outer surface.
    • 刚性塑料微孔泡沫的核心面板或箱体设置有平行隔开的通道或细槽,并且放置在不透气体的柔性多层阻挡膜的信封或袋内。 袋子包括一个整体排出的管状部分,其可释放地联接到由具有电磁阀的歧管连接到真空泵的抽空喷嘴。 在空气基本上从泡沫芯和袋子抽出以将袋子折叠在泡沫芯上并进入凹槽之后,真空传感器操作计算机,该计算机控制阀门以检查袋子内的真空度,并且可选地允许添加气体 。 在泡沫板的相对侧面内紧密间隔开的凹槽用于弯曲抽真空的面板,并将一薄层的泡沫施加到真空绝热板的外表面以提供保护外表面。
