열교환기의 냉매튜브와 그 제조방법 {COOLANT TUBE OF HEAT EXCHANGER AND PROCESSING METHOD THEREOF}Refrigerant tube of heat exchanger and its manufacturing method {COOLANT TUBE OF HEAT EXCHANGER AND PROCESSING METHOD THEREOF}

본 발명은 에어콘의 방열기용 등으로 이용되는 열교환기의 헤더파이프 사이에 다수의 냉매순환용 냉매튜브를 제조하기 위해 판재 상태의 소재를 절곡시켜 여러개의 유로가 형성되는 일체형의 냉매튜브를 제조하고 상기 절곡형성되는 냉매튜브의 양단을 브레이징하여 접합시키도록 하는 냉매튜브의 제조에 있어서, 상기 유로들이 형성되는 절곡부에는 상기 유로들이 서로 유통되는 유통홈을 형성하여 냉매의 흐름을 원활히 하고 열교환효율을 증대시킬 수 있도록 한 열교환기의 냉매튜브와 그 제조방법에 관한 것이다.The present invention is to manufacture an integral refrigerant tube in which a plurality of flow paths are formed by bending a material in a plate state in order to manufacture a plurality of refrigerant circulation refrigerant tubes between header pipes of a heat exchanger used for a radiator of an air conditioner. In the manufacture of a refrigerant tube for brazing both ends of the refrigerant tube to be bent to form a joining, the bent portion in which the flow path is formed to form a distribution groove through which the flow path is flowed to facilitate the flow of the refrigerant and increase the heat exchange efficiency It relates to a refrigerant tube of a heat exchanger and a method of manufacturing the same.

일반적으로 에어콘의 방열기등으로 이용되는 콘덴서 등의 열교환기는 알루미늄으로 된 헤더파이프를 설치하고 있으며 이 헤더파이프에는 여러개의 냉매순환용 냉매튜브를 삽입설치하고 상기 냉매튜브를 따라 냉매가 순환되면서 방열작용을하여 열교환이 이루어지도록 되어 있었다.In general, heat exchangers such as condensers used as radiators of air conditioners are provided with a header pipe made of aluminum. In this header pipe, a plurality of refrigerant circulation tubes are inserted into the header pipe, and the refrigerant is circulated along the refrigerant tube to perform heat dissipation. Heat exchange was achieved.

한편, 상기와 같이 구성된 헤더파이프에 설치되는 냉매튜브를 형성함에 있어서 종래에는 냉매튜브를 압출수단으로 압출성형하되, 상기 냉매튜브의 내부에 여러개의 냉매 순환용 유로가 형성되도록 하여 제조하거나, 상기 냉매튜브만을 압출수단으로 성형하고 이의 내부에 인너핀을 삽입설치하여 여러개의 냉매 순환용 유로가 형성되도록 하고 상기 유로들을 통하여 냉매가 흐르면서 방열작용을 하도록 구성되어 있었으며, 상기 냉매튜브들의 사이에 각각의 방열핀을 설치하여 구성되어 있었다.On the other hand, in forming a refrigerant tube to be installed in the header pipe configured as described above, the extrusion tube is conventionally molded by extrusion means, and manufactured by forming a plurality of refrigerant circulation passages in the refrigerant tube, or the refrigerant Only the tube was formed by extrusion means, and inner pins were inserted into the inner tube to form a plurality of refrigerant circulation flow paths, and the heat dissipation action was performed as the refrigerant flows through the flow paths. Was configured by installing it.

그러나, 상기와 같은 종래의 것은 상기 냉매튜브를 제조함에 있어서, 상기와 같이 압출수단에 의하여 냉매튜브를 성형하고 이의 내부에 압출형의 유로나 인너핀의 삽입에 따른 유로가 형성되도록 제조하기 때문에 상기 유로가 형성되는 냉매튜브의 제조작업이 난해하고 번거롭게 되었으며, 이에 따라 제조공수가 많이 들게 되고 상기 유로를 형성하기 위한 압출작업이나 인너핀의 성형에 따른 금형의 제작이 난해하면서 압출수단의 압출력을 일정하게 유지해야만 했으며, 상기 압출력이 불규칙할 경우에는 상기 냉매튜브의 두께와 유로의 형상이 불량하게 되고 상기 냉매튜브에 형성되는 유로들이 완전히 분리되기 때문에 이들 사이로 흐르게 되는 냉매가 직선상태로 흐르게 되며 이에 따라 냉매의 방열면적을 보다 확대시킬 수 없게 되면서 소재의 낭비가 심하게 되고 또, 상기 유로들이 서로 바이패스될 수 있는 기능이 없기 때문에 상기 유로가 막히거나 할 경우에는 상기 냉매의 흐름이 원활하지 못하여 열교환기의 성능을 저하시키게 되는 점 등의 문제점이 있었다.However, in the conventional method as described above, in the manufacturing of the refrigerant tube, the refrigerant tube is formed by the extrusion means as described above, and is manufactured so as to form a channel according to the insertion of the extrusion type flow path or the inner pin therein. The manufacturing operation of the refrigerant tube in which the flow path is formed becomes difficult and cumbersome, and thus, a lot of manufacturing labor is required, and the extrusion force of the extrusion means is constant while the extrusion work for forming the flow path or the manufacture of the mold according to the molding of the inner pin is difficult. If the extrusion force is irregular, the thickness of the refrigerant tube and the shape of the flow path become poor and the flow paths formed in the coolant tube are completely separated, so that the refrigerant flowing between them flows in a straight state. As a result, the heat dissipation area of the refrigerant cannot be expanded. The hard and In addition, there is a problem in that, because such a feature that the flow path can be by-pass each other and thereby, the lower the performance of the heat exchanger failure to smooth the flow of the refrigerant, or if the flow path is blocked.
