Abstract

본 발명은, 편평튜브(1)를 그 폭방향으로 절곡성형한 절곡형상 열교환기이면서, 제조가 용이하고 내부압력 손실이 적을 뿐 아니라, 열교환효율에 우수한 것을 제공하는 것을 목적으로 한다.
상기한 목적을 달성하기 위하여, 복수개의 편평튜브(1)를 그 두께방향으로 소정의 간격을 두고 서로 평행형상으로 배치하고, 그 양끝에 한쌍의 중공헤더(5), (6)를 연통접속한다. 그리고, 각 편평튜브(1)를 그 길이방향의 적당한 개소에 있어서 튜브 폭방향으로 절곡형성하는 동시에, 그 절곡부위를 그 양측의 직관형상부(2), (3)에 대하여 소정의 각도로 비틀림형성하여 비틀림절곡부(4)를 구성하게 한다. 인접하는 직관형상부(2), (3) 상호간에 핀(11), (12)을 개재하여 배치한다.
