Abstract

본 발명은 튜브 외부에 열 교환기를 통해 유동하는 유체가 튜브를 통해 유동하는 냉각 유체에 열 전달하므로써 응축되는 쉘 및 튜브형 공조 시스템 응축기와 같은 적용예에서 사용하기 위한 열 전달 튜브(10)에 관한 것이다. 튜브는 외부 면(13) 주위로 나선형으로 연장된 적어도 하나의 핀 회선(20)을 갖는다. 노치(30)의 패턴은 튜브의 원주에 대해 소정 간격으로 핀 회선에 대해 경사각(α)으로 연장된다. 각 쌍의 인접 노치 사이에는 스파이크(22)가 있다. 핀 회선, 노치 및 스파이크 맨드릴과, 첫째 피닝 디스크(63)의 갱, 둘째, 노칭 휠(66)사이에서 튜브 벽을 롤링함으로써 튜브에 형성된다. 튜브의 제조중, 회전하며 진행하는 튜브와 노칭 휠의 상호 작용에 의해, 스파이크의 팁의 축의 경사각의 각도(β)는 노치 각에 대해 경사진다. 스파이크의 최대 폭(WT)은 핀 회선의 인접부의 폭(WR) 보다 크다.

CS238084B1 (cs) Zařízení se týká technologie tváření tlustostěnných bezešvých trubek. Účelem vynálezu je zajistit zařízení, které by současně za studená vyválcovalo vnější tenkostěnná žebra ze základního materiálu trubky při současném tváření podélné drážkované struktury na vnitřním povrchu trubky. Uvedeného· účelu se dosahuje sousta**· vou tří vnějších diskových kotoučů sestavených z tvářecích disků, jejichž vnější průměr je kontinuálně odstupňován tak, že se jeho obrys blíží svým tvarem parabole, a vnitřním drážkovacím trnem, opatřeným na povrchu rovnoměrně po obvodu upravenými brity, přičemž povrch břitů je v osovém' směru kuželově sešikmen^v poměru 1 : 500 až 1 : 2000. Odstupňované tvářecí disky vtlačují materiál trubky mezi břity drážkovacího trnu a současně vyválcovávají vnější radiální tenkostěnná žebra z vnějšího povrchu trubky.
