초록

전도 열전달 분야에서 두 물체가 접해 있는 경우, 접촉 열저항은 고려해야 할 중요한 요소이다. 특히 최근에는 전자부품의 과열방지를 위한 열 소산과 관련하여 접촉 열저항 문제는 중요하게 대두되고 있으며 이에 관련한 많은 이론적 연구와 응용연구가 수행되고 있다. 접촉 열저항은 주로 거친 두 물체표면의 불완전접촉에 기인한다. 본 연구에서는, 접촉하는 두 물체사이의 접촉면을 이상화시킨 비교적 간단한 문제를 이론적으로 해석함으로써 접촉면의 틈새 형상 및 비접촉면적비(비접촉면적/외관접촉면적)의 크기에 따른 접촉 열저항의 크기를 구하였다.
