초록
A cooling system that applies double collision jet is studied. To create a jet, a square edge type nozzle is used as its shape. The impinging jet that composes a cooling system which applies double impinging jet is created in the single nozzle and double nozzle that correspond to each LED where the cooling zone exists. The distance between the 2nd nozzle and LED with heat sink is where the LED package is established. The main variation and the standard is examined for four different cases through the way out diameter of 1st nozzle. The examined velocity distribution and temperature distribution about the cooling system consisted of single and double nozzle. It was found that an individual LED consisting of double nozzle was efficient.

The distance between the 2nd nozzle and LED with heat sink is where the LED package is established. The main variation and the standard is examined for four different cases through the way out diameter of 1st nozzle.
