Abstract：
Develops a new type of swirling cold air diffuser and tests its performance in aspects of aerodynamics, cold air supply and noise. The results show that the diffuser has such advantages as larger induction ratio, low resistance and noise, relatively even air supply, no condensation, simple in structure and low in costs.
