System using radiation of far infrared ray for heat release

Abstract

Provided is a system having a heat source unit, and a first heat releasing member arranged on the heat source unit or at a location near the heat source unit, to convert heat into a far infrared ray and radiate the far infrared ray. The provided system uses the heat releasing member formed of a material for converting heat into a far infrared ray and radiate the far infrared ray and vice versa, thus the heat is efficiently exhausted to the outside without increasing the inner temperature of the unit.

       11 . An optical scanning unit comprising: 
 a beam deflector unit including a beam deflector for deflecting and scanning a light beam and a driving motor for rotating the beam deflector at a high speed;    an optical unit including a light source and an image forming optical system for forming images from the deflected light beam, which is input from the light source to the beam deflector and scanned by the beam deflector unit;    a main frame containing the beam deflector unit and the optical unit;    a sub-frame surrounding the beam deflector unit to reduce noise generated by the beam deflector unit in the main frame and having a passage for passing the light beam between the beam deflector unit and the optical unit; and    a first heat releasing member arranged on an outer surface of the sub-frameto convert heat generated in the sub-frame into a far infrared ray and radiate the far infrared ray:    
   
   
       12 . The optical scanning unit of  claim 11  further comprising: 
 a second heat releasing member arranged on an inner surface of the main frame to convert the far infrared ray radiated to the inside of the main frame by the first heat releasing member into heat; and    a third heat releasing member arranged on an outer surface of the main frame to convert heat conducted through the main frame into a far infrared ray and radiate the far infrared ray to the outside.
