AI Technical Summary
Technical Problem
Existing exterior wall decorative louvers tend to accumulate heat under direct sunlight, causing heat to be continuously conducted to the exterior wall, shortening their service life, and they lack adaptive control functions.
Method used
The expansion rubber and adjustable components, which utilize the principle of thermal expansion and contraction, achieve adaptive ventilation and heat dissipation and cold insulation through mechanical adjustment, while the hydrophobic components prevent rainwater accumulation.
Benefits of technology
Effective heat dissipation prevents heat conduction, extends service life, enables adaptive adjustment, reduces noise and rainwater accumulation, and improves operational stability.

Abstract
This application provides a decorative louver for exterior wall shading, relating to the field of louver technology. The decorative louver for exterior wall shading includes a louver frame with a hollow cavity inside. An inspection window, compatible with primary and secondary expansion rubber, is located on the outer side of the louver frame near the hollow cavity. An inspection cover is engaged in a stepped slot. Small installation holes are arrayed on both the upper and lower sides of the louver frame near the pre-reserved slot. During high-temperature thermal expansion, the outer and inner adjustment holes align with the outer and inner louver holes, opening the channels for ventilation and heat dissipation, preventing heat accumulated within the louver frame from being conducted to the exterior wall area, and facilitating timely heat dissipation. During low-temperature contraction, the outer and inner adjustment holes misalign with the outer and inner louver holes, sealing the channels and preventing external cold sources from being conducted to the exterior wall area through the louver frame. This effectively blocks the cold source, achieving cold insulation.
