Abstract
The invention discloses a method for improving the thermal radiation of an aluminium radiator. The method comprises the following steps of: uniformly mixing black powder particles, Al2O3 particles and water according to the ratio of 25:15:100, putting the mixture into a stainless steel stirrer, stirring for more than 3 hours at high speed, then reducing the stirring speed and leading the mixed liquid to swirl softly in the container; completely immersing the aluminium radiator into the mixed liquid for more than 3 seconds after being cleaned by weak acid, and then taking out the aluminium radiator; and conveying the aluminium radiator into an oven for 15 minutes at the temperature of 120-140 DEG C. The ball diameter of the black powder particle is 10-30nm, and the ball diameter of the Al2O3 is 2-5nm. In the aluminium radiator treated by adopting the method, the radiating capability is obviously improved, and the light attenuation and the service life of an LED chip are greatly guaranteed.
