The present invention relates to a method for coating carbon nanoparticles on a heat pipe which coats carbon nanoparticles on the inner circumferential surface of the heat pipe in order to enhance a heat transfer effect of the heat pipe in which working fluid emits or absorbs heat while circulating inside the heat pipe. The method for coating carbon nanoparticles on the heat pipe which coats carbon nanoparticles on the inner circumferential surface of the heat pipe in order to enhance a heat transfer effect of the heat pipe, in which working fluid dissipates or absorbs heat while circulating inside the heat pipe, comprises the steps of: forming a capillary groove in the inner circumferential surface of the heat pipe in the longitudinal direction of the heat pipe, such that the working fluid of a liquid phase moves along the heat pipe; heating and expanding the heat pipe which has the capillary groove in order to make absorption of carbon nanoparticles easy; passing a carbon nanoparticle dispersion through the capillary groove in the state where the heat pipe is heated and expanded so as to absorb the carbon nanoparticles; and cooling and contracting the heat pipe in order to fix the carbon nanoparticles absorbed on the capillary hole.
