Abstract:
An airflow balancer for a ventilation outlet, comprising:an air guider comprising an airflow baffle having a plurality of ventilating slots for allowing an airflow passing through and a supporter which is provided at a rotation center of said airflow baffle for supporting said airflow baffle on said ventilation outlet in a rotatable manner without any physical contact with said ventilation outlet; and a rotor coaxially and upwardly extended from said air guider to form an integral body, wherein said rotor is shaped and sized in such manner that, in response to said airflow passing through said rotor, said rotor is driven to rotate, so as to drive said air guider to rotate, thereby a rotational movement of said air guider is adapted for evenly diffusing said airflow through said ventilating slots toward said ventilation outlet.
