aluminum alloy windows in the t-shaped cross section to increase the heat insulation bar (Azon).

摘要

the design of heat insulation windows in the area (Azon) about.;according to this idea, the number of heat insulation and thermal conductivity, to prevent the add method in the cold state, cooling damage. parts of the shear zone (Azon) and prevent system play a role to be able to achieve in the design that it ubbf8ub284 extrusion zone (Azon) filling it with parts of t shape design of adiabatic expansion to provide a windows to sleep.
