Abstract

전열관의 외면에는 관축방향으로 직교 또는 경사지는 방향으로 뻗는 핀(1)이 설치되어 있다. 이 핀(1)은 0.2 내지 0.8mm의 높이이고, 관축방향 1m당의 핀수는 905 내지 1102열로 설정되어 있다. 핀(1)의 꼭대기부에는 핀을 따라 홈부(3)가 설치되어 있다. 이 홈부(3)의 양측벽면이 이루는 각도는 70°내지 150°로 설정되어 있다. 또한, 핀(1)에는 0.5 내지 1.0mm의 배열피치로 절결부(2)가 설치되어 있다. 이에 의하여 그외면에 부착한 냉매의 젖어퍼짐이 뛰어나고, 또한 표면적이 크고, 전열성능이 뛰어난 유하액막식 증발기용 전열관이 얻어진다.
