Envelope for a Laminar Structure Providing Adaptive Thermal Insulation

摘要

The present invention relates to an envelope (20) for a laminar structure (100) providing adaptive thermal insulation, the envelope (20) enclosing at least one cavity (16) having included therein a gas generating agent (18) having an unactivated configuration and an activated configuration, the gas generating agent (18) being adapted to change from the unactivated configuration to the activated configuration, such as to increase a gas pressure inside the cavity (16), in response to an increase in temperature in the cavity (16), the envelope (20) having, in the unactivated configuration of the gas generating agent (18), a flat shape with a thickness (d) of the envelope (20) being smaller than a lateral extension (A) of the envelope (20), the envelope (20) being configured such that the thickness (d) of the envelope (20) increases in response to the increase in gas pressure inside the cavity (16), the cavity including at least a first sub-cavity (16a) and a second sub-cavity (16b) at least partially stacked above each other in the thickness direction of the envelope (20), the first sub-cavity (16a) and the second sub-cavity (16b) being in communication with each other to allow transfer of the gas generating agent (18), at least in its activated configuration, between the first and second sub-cavities (16a, 16b).

1. Envelope for a laminar structure providing adaptive thermal insulation, the envelope enclosing at least one cavity having included therein a gas generating agent having an unactivated configuration and an activated configuration,
the gas generating agent being adapted to change from the unactivated configuration to the activated configuration, such as to increase a gas pressure inside the cavity, in response to an increase in temperature in the cavity, the envelope having, in a condition with the gas generating agent in the unactivated configuration thereof, a flat shape with a thickness (d=d0) of the envelope being smaller than a lateral extension (Ax=Ax0, Ay=Ay0) of the envelope (20), the envelope being configured such that the thickness (d) of the envelope increases in response to the increase in gas pressure inside the cavity, the cavity including at least a first sub-cavity and a second sub-cavity at least partially stacked above each other in thickness direction of the envelope, the first sub-cavity and the second sub-cavity being in communication with each other to allow transfer of the gas generating agent, at least in the activated configuration thereof, between the first and second sub-cavities.
