摘要: An electrostatic evacuated insulating sheet comprises two permanently charged electret repulsion layers (18 and 28) laminated to respective (16 26), which are in turn impermeable metallic compensation (14 24). The foregoing laminate is then covered by protective (12 22). sufficiently with monopolar electric charges so that, Coulomb force, a small (1 20 micron) space established maintained between the layers. This sufficient stop all heat transfer through convection or conduction. resulting vacuum insulated very thin (1.2 mm 2.9 mm) flexible. It provides an greatly improved performance over any previous flexible insulation, equivalent at least 170 of polystyrene foam.
