본 고안은 냉각수를 내입하고 있는 전열관과 전열관의 양측부에 위치되는 관판사이를 용접하지 않도록하여 용접부위에서 흔히 발생되는 균열현상 다시말하면 버너의 작동에 의하여 가열 또는 냉각되는 작동이 여러번 반복됨에 따라 냉수를 내입하고 있는 전열관과 측판의 열팽창 차이에 기인하여 관판과 전열관의 용접부가 경화되어 발생되는 균열현상을 미면에 방지할 수 있도록 하여 장기간 동안 사용이 가능하도록 한 열교환기에 관한 것이다.The present invention prevents welding between the heat transfer tube into which the coolant is introduced and the tube plates located on both sides of the heat transfer tube. The present invention relates to a heat exchanger that can be used for a long time by preventing cracks caused by the hardening of the welded portion of the tube plate and the heat pipe due to the difference in thermal expansion between the inner heat pipe and the side plate.
종래에 알려진 열교환기로서 일본국 공개실용신안공보(공고번호 : 실개소 56-99290호)에 기재된 것이있는데 이와같은 열교환기는 첨부도면 제1도 및 제2도에 도시한 바와같이 한쌍의 관판(A) (A)의 양측 후렌지부(B) (B)를 한쌍의 측판(C) (C)과 용접 고착하여 버너(D)의 연소 열기에 의하여 전열관(E)내의 냉수를 가열하도록 하였다. 예를들면 순간온수기등의 열교환기로서 사용할 경우에는 내부에 냉수를 내입한 전열관(E)과 그 전열관과 비교하여 고온으로 되는 측판(C)간에는 열팽창의 차이가 있게 된다.Conventionally known heat exchangers include those disclosed in Japanese Laid-Open Utility Model Publication (Publication No. 56-99290). Such a heat exchanger includes a pair of tube plates (A) as shown in FIGS. 1 and 2 of the accompanying drawings. Both side flange parts (B) and (B) of (A) were welded to a pair of side plates (C) and (C) to heat cold water in the heat transfer pipe (E) by combustion heat of the burner (D). For example, when used as a heat exchanger such as an instant water heater, there is a difference in thermal expansion between the heat transfer tube E having cold water introduced therein and the side plate C becoming a high temperature as compared with the heat transfer tube.
그리고 버너(D)의 ON,OFF에 의한 가열ㆍ냉각이 반복됨에 따라 전열관(E)과 측판(C)이 핀(pin) (F)과 비교할때 그 두께가 두껍게 형성되어 있기 때문에 관판(A)과 전열관(E)의 용접부(G)가 경화되어 나중에는 균열이 생기는 결함이 있다.As the heating and cooling by the ON and OFF of the burner (D) are repeated, the heat pipe (E) and the side plate (C) are thicker than the fin (F), so the tube plate (A) The weld part G of the heat exchanger tube E hardens | cures, and there exists a defect which a crack produces later.
본 고안은 이와같은 결함을 해소하여 내구성이 좋은 열교환기를 제공하는 것을 목적으로 한 것으로 이를 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.The present invention aims to provide a heat exchanger having high durability by eliminating such defects, which will be described in detail with reference to the accompanying drawings.
한쌍의 관판(1) (1)사이에 전열관(2)을 삽입시키는 핀칼라(pin collar) (3)와 연결되는 절결부(4)를 형성한 다수의 핀(5)을 측판(11)사이에 연속으로 고정시키고 용접부재(6)를 절결부(4)에 삽입하여 용접 고착하는 것에 있어서 관판(1) (1)에 인접하는 한쌍의 핀을 핀칼라(3)는 형성되고 절결부는 없는 핀(5A) (5A)으로 구성한 것을 특징으로 한 것이다.A plurality of fins 5 having a cutout portion 4 connected to a pin collar 3 for inserting the heat transfer tube 2 between the pair of tube plates 1 and 1 between the side plates 11. The pin collar 3 is formed without a cutout and a pair of pins adjacent to the tube plate 1 and 1 when the welding member 6 is inserted into the cutout 4 and fixed in welding. It is characterized by consisting of pins 5A and 5A.
첨부도면 제3도와 같이 다수의 핀(5)은 내부로 냉각수가 통과하는 전열관(2)을 삽입시길 수 있는 핀칼라(3)를 형성함과 동시에 봉상의 용접부재(6)를 삽입시킬 수 있도록 핀칼라(3)이 연결되는 절결부(4)가 형성되어 있다.As shown in FIG. 3, the plurality of fins 5 form a fin collar 3 through which the heat transfer tube 2 through which the coolant passes can be inserted therein, and at the same time, the rod-like welding member 6 can be inserted therein. The notch part 4 to which the pin collar 3 is connected is formed.
제4도는 절결부가 없는 핀(5A)을 나타낸 것으로서 상기의 전열관(2)만 삽입되도록 한 핀칼라(3A)만 형성되어 있다. 또한 다수의 핀(5) 및 절결부가 없는 핀(5A)은 동일한 판 두께로 형성되어 있고 이보다 두꺼운 판으로 형성되어 있는 한쌍의 관판(1) (1)에 전공된 소공(8)과 핀(5) (A)에 형성된 핀칼라(3) (3A)의 내경은 전열관(2)의 외경보다 약간 크게 형성되어 있다.FIG. 4 shows fins 5A without cutouts, in which only fin collars 3A are formed so that only the heat transfer tubes 2 are inserted. In addition, the plurality of pins 5 and the pins 5A without cutouts are formed with the same plate thickness, and the small holes 8 and the pins majored in a pair of tube plates 1 and 1 formed of thicker plates. 5) The inner diameter of the fin collars 3 and 3A formed in (A) is slightly larger than the outer diameter of the heat exchanger tube 2.
첨부도면 제5도에 의하여 본 고안의 열교환기의 구성을 설명하면 1개의 관판(1),1장의 절결부가 없는 핀(5A), 절결부(4)가 있는 다수의 핀(5)의 순으로 조립한 다음 전열관(2)을 소공(8)과 핀칼라(3A) (3)를 순차적으로 통과하게 삽입시킨다. 그리고 용접부재(6)를 다수의 핀(5)에 형성된 절결부(4)에 삽입시키고 1장의 절결부가 없는 핀(5A)과 1개의 관판(1)의 순으로 전열관(2)에 삽입하여 조립하고 전열관(2)을 확관시켜 고정시킨다. 최종적으로 극관(9)과 전열관(2) 및 관판(1)의 후렌지부(10)와 측판(11)을 용접등에 의하여 임시 고정시킨 다음 고온로 내에서 용접시킨다. (12)는 버너로서 그 연소열기에 의하여 전열관(2)내의 냉각수가 가열되도록 되어 있다.Referring to the configuration of the heat exchanger of the present invention according to Fig. 5, the order of one tube plate 1, one fin 5A without one cutout, and the plurality of fins 5 with the cutout 4 After assembly, the heat pipes 2 are inserted into the small holes 8 and the pin collars 3A and 3 sequentially. Then, the welding member 6 is inserted into the cutouts 4 formed on the plurality of fins 5 and inserted into the heat transfer pipe 2 in the order of the pins 5A without one cutout and the one tube plate 1. Assemble and expand heat pipe (2) and fix it. Finally, the flange 10 and the side plate 11 of the cathode tube 9, the heat transfer tube 2, and the tube plate 1 are temporarily fixed by welding, and then welded in a high temperature furnace. Reference numeral 12 denotes a burner so that the cooling water in the heat transfer pipe 2 is heated by the combustion heater.
이상에 설명한 바와같이 용접부재(6)는 한쌍의 절결부가 없는 핀(5A) (5A)에는 삽입될 수 없으므로 고온로 내에서 용접하였을때도 관판(1) (1)에 인접하는 1조의 핀(5A)은 핀칼라(3A)에 의하여 용접부재(6)가 용융되어 관판(1)측으로 유출될 수 없으므로 관판(1)과 전열관(2)은 용접되지 아니한다.As described above, since the welding member 6 cannot be inserted into the pins 5A and 5A without a pair of cutouts, a pair of pins adjacent to the tube plate 1 and 1 even when welded in a high temperature furnace ( 5A), because the welding member 6 is melted by the pin collar 3A and cannot flow out to the tube plate 1 side, the tube plate 1 and the heat transfer tube 2 are not welded.
따라서 상술한 바와같이 버너의 ON,OFF에 의한 가열, 냉각의 반복에 의하여 관판(1)과 전열관의 용접부가 경화되므로서 균열이 생기는 결함을 확실하게 해소시켜 내구성이 좋은 열교환기를 제공할 수 있는 효과를 가지고 있다.Therefore, as described above, the welding part of the tube plate 1 and the heat transfer tube is hardened by repeated heating and cooling by the ON and OFF of the burner, thereby reliably eliminating the defects that are generated by the crack, thereby providing a durable heat exchanger.
