AI Technical Summary
Technical Problem
The sudden changes in cross-section, baffles, corners and obstacles in the air conditioning duct of a car cause large local airflow pressure and velocity gradients, generating eddies, which become the main source of noise. At the same time, the large wall thickness results in a heavy weight.
Method used
The air conditioning duct has a wall thickness of 0.2-0.4mm, with reinforcing strips and rods welded to the inner wall, and sound-absorbing cotton is glued to the inner wall to reduce noise and enhance structural strength.
Benefits of technology
A lightweight air conditioning duct structure was achieved, while effectively reducing wind noise and maintaining sufficient strength.
