초록
A cooling system that applies impinging 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 impinging jet is created in the nozzle plate that correspond to each LED where the cooling area exists. The distance(d) between the nozzle plate and LED plate with heat sink is where the LED light is established. The main variation and the standard is examined for four different cases through the way out diameter of nozzle plate exit(D). The examined velocity distribution and temperature distribution about the impinging jet cooling system consisted of nozzle plate. It was found that an individual LED consisting of nozzle plate was efficient.
