Description
본 발명은 에어콘의 방열기용 등으로 이용되는 열교환기의 헤더파이프 사이에 다수의 냉매순환용 냉매튜브를 설치함에 있어서, 판재 상태의 소재를 압축소성시켜 여러개의 유로가 형성되는 상기 냉매튜브를 제조하고 상기 압축소성되는 냉매튜브의 양단을 브레이징하여 접합시키도록 하며, 상기 유로들의 사이에 유로들이 서로 유통되는 유통홈을 형성하여 냉매의 흐름을 원활히 하고 열교환효율을 증대시킬 수 있도록 한 열교환기의 냉매튜브에 관한 것이다.In the present invention, in the installation of a plurality of refrigerant circulating refrigerant tubes between the header pipes of the heat exchanger used for the radiator of the air conditioner, by producing a plurality of flow paths by compression-fired the material of the plate state to form the refrigerant tube Brazing both ends of the compression-fired refrigerant tube to be bonded to each other, and between the flow path to form a distribution groove that flows through each other to facilitate the flow of the refrigerant and to increase the heat exchange efficiency of the refrigerant tube of the heat exchanger It is about.
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 냉매튜브(101)를 형성함에 있어서 종래에는 도 1에서와 같이 냉매튜브(101)를 압출수단으로 압출성형하되, 상기 냉매튜브(101)의 내부에 여러개의 냉매 순환용 유로(102)가 형성되도록 하여 제조하거나, 상기 냉매튜브(101)만을 압출수단으로 성형하고 이의 내부에 인너핀(103)을 삽입설치하여 여러개의 냉매 순환용 유로(104)가 형성되도록 하고 상기 유로(102)(104)들을 통하여 냉매가 흐르면서 방열작용을 하도록 구성되어 있었으며, 상기 냉매튜브(101)들의 사이에 각각의 방열핀을 설치하여 구성되어 있었다.Meanwhile, in forming the refrigerant tube 101 installed in the header pipe configured as described above, the refrigerant tube 101 is conventionally extruded by extrusion means, as shown in FIG. 1, but several inside the refrigerant tube 101. It is manufactured by forming the refrigerant circulation flow path 102 of, or by forming only the refrigerant tube 101 by the extrusion means and the inner pin 103 is installed therein to form a plurality of refrigerant circulation flow path 104 is formed. It was configured to the heat dissipation action as the refrigerant flows through the flow path (102, 104), and was provided by installing each heat radiation fin between the refrigerant tubes (101).
그러나, 상기와 같은 종래의 것은 상기 냉매튜브(101)를 제조함에 있어서, 상기와 같이 압출수단에 의하여 냉매튜브(101)를 성형하고 이의 내부에 압출형의 유로(102)나 인너핀(103)의 삽입에 따른 유로(104)가 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 냉매튜브(101)의 두께와 유로의 형상이 불량하게 되고 상기 냉매튜브(101)에 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 열교환기의 성능을 저하시키게 되는 점 등의 문제점이 있었다.However, in the conventional method as described above, in manufacturing the refrigerant tube 101, the refrigerant tube 101 is formed by the extrusion means as described above, and an extrusion-type flow path 102 or an inner pin 103 therein. The manufacturing process of the refrigerant tube in which the flow path is formed is difficult and cumbersome because the flow path 104 is formed according to the insertion of the flow path 104. Therefore, a lot of manufacturing labor is required and the extrusion work or the molding of the inner pin to form the flow path While the production of the mold was difficult, the extrusion force of the extrusion means had to be kept constant, and when the extrusion force was irregular, the thickness of the refrigerant tube 101 and the shape of the flow path became poor and the refrigerant tube 101 Since the flow paths formed in the chamber are completely separated, the refrigerant flowing between them flows in a linear state, thereby increasing the heat dissipation area of the refrigerant. There was a problem such that the waste of the material becomes severe and the performance of the heat exchanger is reduced.
