A method for manufacturing a tube for a transverse heat exchanger and a tube for a transverse heat exchanger manufactured by the method

The present invention relates to a tube for a horizontal heat exchanger and a method for manufacturing the same, which may form a low fin which reduces the flow of a refrigerant on the outer surface of a tube provided at a horizontal heat exchanger to improve heat transfer performance such that a cooling water to cool a refrigerant may flow. Furthermore, the present invention allows a tube to be processed in a spiral shape to improve heat transfer performance by reducing the flow speed of the cooling water, thereby maximizing the heat transfer performance and reducing the size, and being used in a condenser and an evaporator at the same time. Here, the present invention relates to the tube for a horizontal heat exchanger, and more specifically, to the tube for a horizontal heat exchanger which is installed at a horizontal heat exchanger such that the cooling water may flow, wherein a tube sheet coupling unit, coupled to the tube sheet of a heat exchanger, is formed at both ends, and a heat exchanging unit is formed between the tube sheet coupling units. Here, the heat exchanging unit has a low fin formed on the outer surface at a predetermined interval while being spirally processed. In addition, the method for manufacturing the tube for a horizontal heat exchanger is characterized by comprising: a tube rolling step of forming a low fin on the outer surface of the tube by using a low fin machine; a spiral processing step of spiral-processing the tube at which the low fin is formed by using the spiral machine; and a straightness correction step of correcting the straightness of the tube which is spirally processed by using a correction jig. 본 발명은 냉매를 냉각시키는 냉각수가 유동하도록 횡형 열교환기에 구비되는 튜브의 외면에 냉매의 흐름을 저하시켜 전열성능을 향상시키는 로우핀을 형성함과 아울러 냉각수의 유속을 저하시켜 전열성능이 향상되도록 튜브를 스파이럴 형상으로 가공함으로써 전열성능을 극대화하여 사이즈를 축소할 수 있으며 응축기와 증발기에서 공용으로 사용할 수 있는 횡형 열교환기용 튜브 및 그 제조방법에 관한 것으로, 횡형 열교환기용 튜브는, 냉각수가 유동하도록 횡형 열교환기에 설치되는 횡형 열교환기용 튜브에 있어서, 양단에 열교환기의 관판에 결합되는 관판 결합부가 형성되고, 관판 결합부 사이에 열교환부가 형성되되, 열교환부는 외측면에 일정 간격으로 로우핀이 형성됨과 아울러 스파이럴 가공된 것을 특징으로 하고, 횡형 열교환기용 튜브의 제조방법은, 로우핀 머신을 이용하여 튜브의 외면에 로우핀을 형성하는 튜브롤링 단계; 스파이럴 머신을 이용하여 로우핀이 형성된 튜브를 스파이럴 가공하는 스파이럴 가공 단계; 교정지그를 이용하여 스파이럴 가공된 튜브의 직진도를 교정하는 직진도교정 단계;를 포함하는 것을 특징으로 한다.
