Abstract

전열 촉진을 위한 핀을 내면 또는 외면에 구비한 핀이 부착된 전열관과 핀이 부착된 박막전열면, 열교환기 및 냉동기와 공기조화기에 관한 것으로, 응축열 및 비등열 전달의 전열성능을 향상시키기 위해, 전열관의 내면 및 외면 중 어느 한쪽 면에 여러개의 핀이 형성된 열교환기에 있어서, 핀의 각각은 이 핀의 꼭대기부를 포함한 제1부분과 이 핀의 근원을 포함한 제2부분을 갖고, 제1부분은 그의 능선이 오목볼록형상 또는 대략 파형을 이루도록 하고, 제2부분은 핀이 형성된 어느 한쪽 면과 평행한 절단면의 핀의 긴쪽방향의 윤곽이 대략 직선형상을 이루도록 구성하였다.
이러한 구성으로 하는 것에 의해, 응축열 및 증발열 전달성을 향상시킬 수 있고, 또한 전체적으로 고정밀도이고 또한 용이한 가공을 실행할 수 있다.
