초록

본 논문은 자동차 LED head lamp의 방열을 위한 히트싱크(heat sink)의 설계요소를 변화시켜 방열특성을 알아보고자 수치해석을 수행하였다. 수치해석에 적용한 히트싱크는 LED를 광원으로 사용하는 기존제품(Type 1)을 바탕으로 한정된 내부공간에 적합하도록 설계하여 5가지 Type으로 설계하였다. 설계된 히트싱크의 수치해석은 ANSYS CFD V12.1을 사용하여 히트싱크의 변화에 따른 온도분포와 평균온도, 공기유동특성, 열유속 등을 분석하였다. 수치해석을 통하여 방열판의 구조와 휜 형상에 따른 방열특성의 상관관계를 도출할 수 있었으며, 설계된 히트싱크의 온도분포, 공기의 유동특성, 열유속 등을 분석한 결과, 히트싱크 Type 2가 다른 Type들에 비해 LED head lamp의 방열을 위해 적합한 특성을 나타내었다.

This thesis was conducted a numerical analysis on the radiant heat performance according to factors of design of heat sink for cooling of the automotive LED head lamp. The heat sinks were designed with 5 different types to fit the limited internal space by formula based on an existing product (Type 1). Designed heat sinks of five types were analyzed by ANSYS CFD V12.1, and the analysis results were compared with the existing type. The results of simulation were analyzed temperature distribution and average temperature, air flow characteristic, heat flux etc. This thesis was researched on the correlation of the cooling performance according to the heat sink structure and the fin shape. Through numerical analysis, could be confirmed heat sink Type 2 as the best results.
