핀 튜브형 열교환기의 제조방법{Method for manufacturing of fin-tube type heat exchange}Method for manufacturing of fin tube type heat exchanger

본 발명은 냉동기 또는 냉동공조장치에 사용되는 콘덴서나 증발기로 사용되는 열교환기에 관한 것으로써, 더욱 상세하게는 열교환매체가 그 내부를 통과하는 스틸 튜브와 스틸 튜브에 스틸 핀을 최대한 접촉시켜 열교환 효율을 향상시키도록 한 핀 튜브형 열교환기의 제조방법에 관한 것이다.The present invention relates to a heat exchanger used as a condenser or an evaporator used in a refrigerator or a refrigeration air conditioner. A method of manufacturing a finned tube heat exchanger is to be improved.

냉동기 또는 공조장치에서는 사용되는 콘덴서나 액체냉매를 저압에서 증발시켜 냉각시켜주는 증발기로 핀 튜브형 열교환기를 사용한다. 열교환매체가 내부를 통과하는 튜브와 상기 튜브의 표면에 접촉되는 핀으로 구성되는 핀 튜브형 열교환기는 제한된 공간에서 최대의 열교환 효율을 얻기위해 다수의 관통공이 형성된 핀들을 적치하고 튜브를 핀에 형성된 관통공에 삽입함으로써 구성된다.In refrigerators or air conditioners, fin tube type heat exchangers are used as evaporators to cool the condensers or liquid refrigerants used at low pressure. Fin tube type heat exchanger consisting of a tube through which heat exchange medium passes through and a fin contacting the surface of the tube, accumulating fins having a plurality of through holes and through holes formed in the fins to obtain maximum heat exchange efficiency in a limited space. It is configured by inserting in.

상기와 같은 핀 튜브형 열교환기를 제작하는 종래의 방법으로는 핀에 관통공을 형성하며 관통공 둘레를 따라 후방으로 절곡부를 형성하고, 다수의 관통공이 형성된 핀을 일정한 간격으로 적치한 상태에서 튜브를 상기 각 핀의 관통공에 삽입한다. 튜브와 핀의 절곡부가 완전히 밀착되지 않으면 튜브와 핀의 열교환이 원활하게 이루어지지 않으므로 핀에 삽입된 튜브의 내부를 초경합금 재질의 플러그 등을 삽입시켜 기계적으로 튜브를 확관시킴으로써 튜브와 핀의 절곡부가 완전히 밀착되도록 한다.In the conventional method of manufacturing a fin tube type heat exchanger as described above, through-holes are formed in the fins, and bent portions are formed along the periphery of the through-holes, and a plurality of through-holes are formed at regular intervals. Insert into the through hole of each pin. If the bent portion of the tube and pin is not completely in contact with each other, the heat exchange between the tube and the fin does not occur smoothly. Therefore, the tube is inserted into the inside of the pin by inserting a cemented carbide plug. Make sure they are in close contact.

그러나 상기와 같은 핀 튜브형 열교환기를 제조방법은 경도가 작은 재질의 튜브의 내부에 경도가 큰 재질의 플러그를 삽입하게 되므로 스틸튜브와 같이 경도가 비교적 크게 되면 플러그를 이용하여 확관하는 방식이 불가능하다.However, the method of manufacturing a fin tube type heat exchanger as described above inserts a plug of a material of high hardness into the tube of a material of low hardness, so when the hardness is relatively large, such as a steel tube, it is impossible to expand the pipe by using a plug.

또한 스틸튜브는 용접부의 비드로 인하여 상기와 같이 확관하는 방식으로 열교환기를 제작할 수 없는 문제점이 있었다.In addition, the steel tube has a problem that can not be produced in the heat exchanger in such a way as to expand because of the bead of the weld.

본 발명은 상기와 같은 문제점을 해결하기 위해 안출된 것으로서, 절곡부가 형성된 핀의 관통공에 튜브를 억지 끼워맞춤 함으로써 핀의 절곡부와 튜브가 완전하게 밀착되도록 한 핀 튜브형 열교환기의 제조방법을 제공하는데 목적이 있다.The present invention has been made to solve the above problems, and provides a method for manufacturing a fin tube type heat exchanger in which the bent portion of the fin and the tube is completely in close contact by forcibly fitting the tube to the through hole of the bent portion formed fin. The purpose is to.

상기와 같은 본 발명의 목적을 달성하기 위해 본 발명의 핀 튜브형 열교환기의 제조방법은 핀에 펀칭 작업에 의해 다수의 관통공을 형성하고, 상기 관통공에 버링 작업으로 절곡부를 형성한 후, 관통공에 튜브를 억지 끼워맞춤하여 핀(21)과 튜브를 밀착시키는 것을 특징으로 한다.In order to achieve the object of the present invention as described above, the manufacturing method of the fin tube type heat exchanger of the present invention forms a plurality of through-holes by punching in the fins, and forms a bent portion in the through-holes by burring, and then through It is characterized in that the pin 21 and the tube are in close contact by forcibly fitting the tube to the ball.

또한 핀에 방사상으로 다수의 돌기와 홈을 갖는 관통공을 일정한 간격으로 형성하고, 상기 핀에 형성된 돌기의 중앙부를 일정한 방향으로 구부려서 절곡부를 형성하며, 상기 핀의 관통공에 튜브를 삽입한 후, 절곡부를 압착하여 핀과 튜브를 밀착시켜 핀 튜브형 열교환기를 제조하는 것을 특징으로 한다.In addition, radially formed through-holes having a plurality of protrusions and grooves in the pin at regular intervals, and bends are formed by bending the central portion of the protrusions formed in the pin in a predetermined direction, and after bending a tube into the through-hole of the pin, It is characterized in that the fin tubular heat exchanger is manufactured by closely contacting the fin and the tube by pressing the part.

또한, 상기의 핀 튜브형 열교환기의 제조방법은 핀 또는 튜브의 재질로 스틸을 사용한 것을 특징으로 한다.In addition, the manufacturing method of the fin tube type heat exchanger is characterized in that the steel is used as the material of the fin or tube.

이하 첨부된 도면을 이용하여 본 발명의 스틸튜브를 사용하는 핀 튜브형 열교환기의 제조방법의 바람직한 실시예를 설명하면 다음과 같다.Hereinafter, a preferred embodiment of the manufacturing method of the fin tube type heat exchanger using the steel tube of the present invention will be described with reference to the accompanying drawings.

스틸핀에 일정한 간격으로 스틸튜브를 삽입할 수 있는 관통공을 형성한 후, 스틸튜브을 상기 관통공에 억지 끼워맞춤 함으로써 핀 튜브형 열교환기를 제조한다.After forming a through hole through which steel tubes can be inserted into the steel fins at regular intervals, a fin tube type heat exchanger is manufactured by forcibly fitting the steel tubes to the through holes.

가공이 용이한 스틸재질의 핀(21)에 스틸튜브(31)를 삽입할 수 있도록 다수의 관통공(22)을 형성한다. 프레스 또는 펀칭머신 등을 이용하여 스틸핀(21)에 펀칭가공을 함으로써 다수의 원형 관통공(22)을 형성한다.A plurality of through holes 22 are formed to insert the steel tube 31 into the pin 21 made of steel, which is easy to process. A plurality of circular through holes 22 are formed by punching the steel pins 21 using a press or a punching machine.

스틸핀(21)에 형성된 관통공(22)에 버링 작업을 통해 이미 형성된 관통공(22)의 지름을 넓히고, 절곡부(23)를 형성하도록 한다. 펀치에의해 형성된 관통공(22)에 버링수단을 이용하여 관통공(22)의 지름을 넓히고, 버링수단이 삽입되는 방향으로 버(burr)를 형성하여 절곡부(23)가 되도록 한다. 관통공(22)에 버링수단을 삽입시킴으로써, 관통공(22)의 지름을 약간 넓히고, 삽입되는 버링수단을 따라 관통공(22)의 둘레를 따라 절곡부(23)가 형성된다.Through the burring operation in the through hole 22 formed in the steel pin 21, the diameter of the through hole 22 already formed is widened, and the bent portion 23 is formed. The diameter of the through hole 22 is widened by the burring means in the through hole 22 formed by the punch, and a burr is formed in the direction in which the burring means is inserted to form the bent portion 23. By inserting the burring means into the through hole 22, the diameter of the through hole 22 is slightly widened, and the bent portion 23 is formed along the circumference of the through hole 22 along the inserted burring means.

다수의 관통공(22)이 형성된 스틸핀(21)에 스틸튜브(31)를 억지 끼워맞춤으로써 열교환기를 제작한다. 스틸핀(21)에 형성된 관통공(22)에 상기 관통공(22)의 의 내경보다 외경이 약간 큰 스틸튜브(31)를 억지 끼워맞춤한다. 관통공(22)의 내경보다 스틸튜브(31)의 외경이 큰 억지 끼워맞춤이므로, 스틸튜브(31)가 관통공(22)으로 삽입될 때 스틸튜브(31)와 관통공(22) 둘레에 형성된 절곡부(23)이 완전히 밀착된다.The heat exchanger is manufactured by forcibly fitting the steel tube 31 to the steel fin 21 having a plurality of through holes 22 formed therein. The steel tube 31 which is slightly larger in outer diameter than the inner diameter of the through hole 22 is forcibly fitted into the through hole 22 formed in the steel pin 21. Since the outer diameter of the steel tube 31 is larger than the inner diameter of the through hole 22, the fitting fits around the steel tube 31 and the through hole 22 when the steel tube 31 is inserted into the through hole 22. The formed bent portion 23 is completely in contact.

펀칭 및 버링 작업이 끝난 다수의 스틸핀(21)을 스틸핀의 절곡부(23)가 같은 방향이 되도록 하여 일정한 간격으로 다이(die)에 고정시킨 후, 스틸핀(21)의 관통공(22)에 스틸튜브(31)를 상기 관통공(22)에 버링 작업시 버링수단이 삽입되는 방향으로 스틸튜브(31)를 삽입시킨다. 스틸핀(21)의 관통공(22)에 스틸튜브(31)가 일정한 간격으로 삽입되도록 한 후, 스틸튜브(31)의 단부를 연결하고 일정한 간격으로 벤딩하여 열교환기를 완성한다.After the punching and burring operations, the plurality of steel pins 21 are fixed to the dies at regular intervals so that the bent portions 23 of the steel pins are in the same direction, and the through holes 22 of the steel pins 21 are fixed. The steel tube 31 is inserted into the steel tube 31 in the direction in which the burring means is inserted in the burring operation. After the steel tube 31 is inserted into the through hole 22 of the steel fin 21 at regular intervals, the ends of the steel tubes 31 are connected and bent at regular intervals to complete the heat exchanger.

When the steel tube 31 'is inserted into the steel pin 21', the steel tube 31 'and the steel pin 21' are not completely in contact with each other. However, the steel tube 31 'and the steel pin are formed by pressing. The heat exchange capacity is improved by making the 21 'closely contact.
