HEAT INSULATING DEVICE Russian patent published in 2017 - IPC E04B1/76 E06B3/67 E04F13/00 E04C2/54 

FIELD: machine building.

SUBSTANCE: present invention relates to heat insulation device, containing, at least, one panel (100), containing two walls (110, 120), separated by external main brace (102) and forming gas-tight chamber (104), and, at least, two flexible films (150, 160) located inside said chamber (104) and made with possibility of selective transition between two states, wherein each pair of adjacent films (150, 160) limits sealed cells (158): heat conducting state, in which said flexible films (150, 160) are, at least, partially in contact with each other, and heat insulation state, in which flexible films (150, 160) are separated one from another, under effect of different pressures inside said leak-tight chamber (104), developed by means of fluid medium control device (170). In heat insulating state distance between flexible films (150, 160), is smaller than mean free path of gas molecules, occupying volume (158), limited between said flexible films (150, 160). In compliance with this invention corresponding method is also disclosed.

EFFECT: invention enables to optimize control of heat insulation taking into account effect of external environment.
