Document Type and Number:
WIPO Patent Application WO/2022/041704
Kind Code:
A1
Abstract:
Disclosed is a new intelligent adjustable passive roof, comprising an inner roof layer, an air layer, a thermal diode of jumping droplet materials, and an outer roof layer, which are sequentially arranged from bottom to top. The thermal diode of jumping droplet materials comprises a super-hydrophilic layer, a super-hydrophilic layer surface liquid-absorbing core and a super-hydrophobic layer, which are sequentially arranged from bottom to top, and the super-hydrophilic layer is separated from the super-hydrophobic layer by gasket materials on left and right sides to form an intermediate air interlayer. According to the present invention, by means of passive heat transfer control of the super-hydrophilic layer and the super-hydrophobic layer in the thermal diode of jumping droplet materials, a new intelligent adjustable passive roof which is driven passively by indoor and outdoor temperatures for heat extraction and heat insulation, does not need to be manually cleaned and can be embedded into a building enclosure structure is formed.
