Description
본 발명은 열교환기에 관한 것으로서, 보다 상세하게는 냉매튜브와 전열핀이 일체로 형성된 핀 튜브 일체형 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, to a fin tube integrated heat exchanger in which a refrigerant tube and a heat transfer fin are integrally formed.
일반적으로 공조기 등에서 사용되는 핀튜브형 열교환기는, 도 1에 나타난 것과 같이 소정 길이의 원형관이 ' ?? ' 형태로 연속 벤딩(bending)되어 일종의 다중겹 형상으로 이루어진 냉매튜브(10)와, 일정한 간격을 두고 다수개가 평행하게 배열되어 용접에 의해 냉매튜브(10)에 부착되며, 외견상 벤딩된 냉매튜브(10)를 가로지르는 형태로 장착되는 얇은 패널형태의 전열핀(12)으로 구성되어 있다.In general, a fin tube type heat exchanger used in an air conditioner or the like has a circular tube having a predetermined length as shown in FIG. 'Bending in the form of a continuous (bending) a kind of a multi-layered refrigerant tube 10, and a plurality of parallel arrangements at regular intervals are attached to the refrigerant tube 10 by welding, apparently bent refrigerant tube It consists of the thin-panel heat-transfer fins 12 mounted in the form which crosses (10).
이와 같은 종래의 핀튜브형 열교환기에 의하면 냉매가 냉매튜브(10)를 통해 유동하는 과정에서 외기와 열교환함으로써 증발기 내지는 응축기로서 작용하게 되며, 전열핀(12)에 의해 냉매튜브(10)의 전열면적이 확대됨으로써 효율적인 열교환작용이 수행된다.According to the conventional fin tube type heat exchanger, the refrigerant acts as an evaporator or a condenser by exchanging heat with outside air in the process of flowing through the refrigerant tube 10, and the heat transfer area of the refrigerant tube 10 is transferred by the heat transfer fins 12. By enlarging, efficient heat exchange is performed.
한편, 핀튜브형 열교환기의 냉매튜브(10)는 열교환효율 향상을 위해 내주면에 다수개의 그루브(groove)(101)가 형성된 구조로 이루어져 있는데, 상기 그루브(101)는 냉매튜브(10)의 길이방향으로 이어지는 스파이럴 형태로 구성되어 있다.Meanwhile, the coolant tube 10 of the fin tube type heat exchanger has a structure in which a plurality of grooves 101 are formed on an inner circumferential surface of the fin tube type heat exchanger to improve heat exchange efficiency. The groove 101 is a longitudinal direction of the coolant tube 10. It consists of spiral form leading to.
이러한 그루브(101)에 의하면 열교환기가 증발기로 사용되어 증발열전달 작용을 행할 경우, 액상의 냉매가 냉매튜브(10)와 접촉하는 면적이 넓을수록 열교환효율이 높기 때문에 접촉면적이 확대되는 효과를 얻을 수 있다.According to the groove 101, when the heat exchanger is used as an evaporator to perform evaporative heat transfer, the contact area is enlarged because the heat exchange efficiency is increased as the liquid refrigerant contacts the refrigerant tube 10. have.
또한, 열교환기가 응축기로 사용되어 응축열전달 작용을 행할 경우에는 기상의 냉매가 냉매튜브(10)와 접촉하는 면적이 넓을수록 열교환효율이 높기 때문에, 응축 생성된 액상 냉매가 그루브(101)를 통해 신속히 배출됨으로써 기상 냉매와 냉매튜브(10)가 신속히 재접촉하는 효과를 얻을 수 있다.In addition, when the heat exchanger is used as a condenser to perform condensation heat transfer, the larger the area where the gaseous refrigerant contacts the refrigerant tube 10, the higher the heat exchange efficiency. By discharging, the gaseous refrigerant and the refrigerant tube 10 can be quickly recontacted.
한편, 이와 같은 종래기술에 따른 열교환기의 제작 시에는 냉매튜브(10)와 전열핀(12)을 결합시키는 과정을 거쳐야 하는데, 냉매튜브(10)와 전열핀(12)의 결합을 위해 서는 냉매튜브(10)를 전열핀(12)에 관통시킨 상태에서 냉매튜브(10)를확관하는 등의 복잡한 작업을 필요로 한다.On the other hand, when manufacturing the heat exchanger according to the prior art such as to go through the process of coupling the refrigerant tube 10 and the heat transfer fin 12, the refrigerant for coupling the refrigerant tube 10 and the heat transfer fin 12 Complicated operations such as expanding the refrigerant tube 10 in a state where the tube 10 penetrates the heat transfer fin 12 are required.
따라서, 상술한 바와 같은 종래기술에 의한 열교환기는 제작과정이 복잡하기 때문에 생산성이 낮고, 냉매튜브(10)가 다수개의 전열핀(12)과 일정한 간격을 두고 반복 결합되어야 하므로 반드시 절곡된 구조로 이루어져야 하는 등, 구조상의 제약이 크다는 문제점을 가지고 있다.Therefore, the heat exchanger according to the prior art as described above is low in productivity because the manufacturing process is complicated, the refrigerant tube 10 must be made of a bent structure because it must be repeatedly coupled with a plurality of heat transfer fins 12 at regular intervals. There is a problem that the structural constraints are large.
또한, 종래기술에 의하면 냉매튜브(10)와 전열핀(12)이 별도의 구조물로서 서로 접하기 때문에 냉매튜브(10)와 전열핀(12) 사이의 간극에서 접촉저항이 발생하여 열전달 효율이 저하된다.In addition, according to the prior art, since the refrigerant tube 10 and the heat transfer fins 12 contact each other as separate structures, a contact resistance is generated in the gap between the refrigerant tube 10 and the heat transfer fins 12, thereby lowering the heat transfer efficiency. do.
본 발명은 상기한 종래 문제점을 해결하고자 안출된 것으로서, 별도의 전열핀을 사용하지 않고, 전열핀과 냉매튜브가 일체 형성된 구조로서 생산성이 향상되고, 구조상 제약이 적고, 열전달 효율이 높은 열교환기 제공을 목적으로 한다.The present invention has been made to solve the above-mentioned problems, and does not use a separate heating fin, the heat transfer fin and the refrigerant tube is integrally formed in the structure is improved productivity, less structural constraints, providing a high heat transfer efficiency heat exchanger For the purpose.
