ABSTRACT:
A rotary structure for radiation fans mainly includes a seat for housing a radiation fan and two brackets coupling with the seat to hold two sleeves. The two sleeves are coupled with two rotary ends of a spindle of the radiation fan to confine the spindle to rotate about a single axis. Thereby the spindle can rotate without skewing while the radiation fan is operating, and impact and noise generation can be prevented.
