The invention discloses a decorative
curtain wall structure, and relates to the technical field of curtain walls. The decorative
curtain wall structure includes a power part and a plurality of cantilevers, the
cantilever heads are arranged in the circumferential direction of the power part at equal distance, the cantilevers and a shell of the power part are integrally formed, the
tail parts of thecantilevers are fixedly connected with ventilation fixing parts, and the ventilation fixing parts pass through a fixed
curtain wall. According to the decorative curtain wall structure, through the power part filled with a condensate, the condensate adopts a
solvent with the
boiling point being 34-46 DEG C,
pentane is taken as an example, the
pentane is in the
liquid state when the
boiling point is less than 36 DEG C, when the outside temperature is increased to the
boiling point of the
pentane or above, due to the fact that the density of gas is far less than that of liquid, the shell internally expands, thus a
piston and a
piston column can be driven to move, as the
piston column moves, a connecting rod is driven to move according to the lever principle, the other side of the connectingrod moves through a joint lever and separates a blocking cover from a sleeve, and at the moment, the two sides of the sleeve communicate through a ventilation hole to dissipate heat.
