AI Technical Summary

Technical Problem

Existing doors and windows have poor heat insulation, resulting in rapid air convection, poor heat insulation and heat preservation performance, and increased frame thickness and weight.

Method used

The design employs a multi-cavity anisotropic thermal insulation strip, including a first multi-cavity anisotropic thermal insulation strip, a second multi-cavity anisotropic thermal insulation strip, and a third multi-cavity anisotropic thermal insulation strip, which are respectively set in the spacer between the inner frame and the outer frame to form multiple insulation cavities, thereby increasing the thermal insulation effect and reducing the overall weight.

Benefits of technology

It improves the thermal insulation performance of doors and windows while reducing the overall weight, thus solving the problem of poor thermal insulation in existing technologies.
