Title
(KO) 방열성능이 향상된 차량 램프용 히트싱크 및 그 제조방법
Abstract
(KO)
본 발명은 열전도도와 열방사율이 우수한 탄소계 코팅액을 히트싱크의 표면에 도포하여 방열성능을 향상시킴과 아울러 방열핀을 생략하여 경량화를 달성할 수 있는 방열성능이 향상된 차량 램프용 히트싱크 및 그 제조방법에 관한 것으로, 방열성능이 향상된 차량 램프용 히트싱크 제조방법은, 탄소계 코팅액을 준비하는 단계(S1)와; 표면처리된 소재의 표면에 탄소계 코팅액을 코팅하는 단계(S2)와; 탄소계 코팅액을 경화 및 냉각시키는 단계(S3)와; 표면검사후 코팅된 소재를 절단 및 포장하는 단계(S4);를 포함하는 차량 램프용 히트싱크 제조방법에 있어서, 상기 탄소계 코팅액을 준비하는 단계(S1)는, 중량%로, 무기물 세라믹 40~55%, 카본블랙 40~55%, 탄소나노튜브 1~4%, 그래핀 0.5~1%로 이루어진 탄소나노 혼합분말을 제조하는 단계(S10)와; 중량%로, 상기 탄소나노 혼합분말 30~50%와, 증류수 30~50%, 분산제 1~10%, 유기산 0.1%, 폴리실록산 5~20%, 유기용제 1~10%를 혼합하여 분산시킨 후 교반 및 응축시켜 탄소나노 혼합용액을 제조하는 단계(S20)와; 중량%로, 상기 탄소나노 혼합용액 50~60%, 에폭시 10~20%, 에폭시 수지 10~20%, 경화제 10~20% 및 시너(Thinner) 10~20%를 혼합하여 코팅액을 형성하는 단계(S30);를 포함하는 것을 특징으로 한다.
