PURPOSE: A heat radiation apparatus of deflection yoke in a CRT is provided to emit easily heat generated in the deflection yoke. CONSTITUTION: A heat radiation apparatus of deflection yoke in a CRT comprises a horizontal deflection coil(2) for deflecting electron beams into the right and left direction, a vertical deflection coil(4) for electron beams into the up and down direction, a holder(8), a ferrite core(6) winding the vertical deflection coil, and a cooling vessel(20). The holder acts as an insulation and a supporter between the horizontal deflection coil and the vertical deflection coil. The cooling vessel is attached to the surface of the holder and the ferrite core and accommodates cooling liquid having a high heat transfer coefficient so as to emit the heat of the ferrite core by using self circulating of the cooling liquid.
