본 발명은 열교환기에 관한 것으로서, 더욱 상세하게는 튜브를 확장하는 기계적인 방법에 의해 튜브와 핀을 결합시키는 열교환기에 있어서, 튜브와 핀과의 접촉 면적을 확대시킴으로써, 튜브와 핀과의 열전도 성능을 향상시킬 수 있는 열교환기에 관한 것이다.The present invention relates to a heat exchanger, and more particularly, in a heat exchanger that couples a tube and a fin by a mechanical method of expanding the tube, by increasing the contact area between the tube and the fin, the heat conduction performance between the tube and the fin is improved. It relates to a heat exchanger that can be improved.

도 1에 도시된 바와 같이, 차량에 구비된 열교환기(10)는 일반적으로 열교환매체가 유입 및 배출되는 입구파이프(11-1) 및 열교환매체가 배출되는 출구파이프(11-2)를 포함하여 일정 이격되어 형성되는 한 쌍의 헤더탱크(11)를 포함하며, 헤더탱크(11)에는 튜브(12)의 양단이 삽입됨으로서, 열교환매체가 튜브(12)를 따라 유동할 수 있다.As shown in FIG. 1, the heat exchanger 10 provided in the vehicle generally includes an inlet pipe 11-1 through which a heat exchange medium is introduced and discharged, and an outlet pipe 11-2 through which the heat exchange medium is discharged. It includes a pair of header tanks 11 formed to be spaced apart from each other, and both ends of the tube 12 are inserted into the header tank 11, so that the heat exchange medium can flow along the tube 12.

아울러, 튜브(12)에는 다수의 핀(13)이 결합되어 형성됨으로써, 주행풍 등에 의해 유동하는 공기를 안내함과 더불어, 공기와 열교환매체 간의 열 교환을 통해 엔진 등에서 공급되어 유동하는 열교환매체를 냉각시킬 수 있다.In addition, the tube 12 is formed by combining a plurality of fins 13, thereby guiding the air flowing by the running wind, etc., and providing a heat exchange medium supplied from the engine or the like through heat exchange between the air and the heat exchange medium. Can be cooled.

튜브(12)와 핀(13) 결합시키기 위한 방법에는 브레이징을 통해 튜브(12)와 핀(13)을 결합시키거나, 튜브(12)를 핀(13)에 삽입한 후, 튜브(12)의 외경 확장에 의한 기계적인 방식에 의해 튜브(12)와 핀(13)을 접촉, 결합시킬 수 있다.In the method for coupling the tube 12 and the fin 13, the tube 12 and the fin 13 are connected through brazing, or after the tube 12 is inserted into the fin 13, The tube 12 and the pin 13 may be contacted and coupled to each other by a mechanical method by expanding the outer diameter.

브레이징을 통해 튜브(12)와 핀(13)을 결합시키기 위해서는 튜브(12) 사이에 절곡된 핀(13)을 위치시키고, 절곡되어 튜브(12)와 만나는 점을 브레이징함으로써, 튜브(12)와 핀(13)을 결합시킬 수 있다.In order to couple the tube 12 and the fin 13 through brazing, by placing the bent fin 13 between the tube 12 and brazing the point where it is bent and meets the tube 12, the tube 12 and the fin 13 The pin 13 can be coupled.

기계적인 방식에 의해 튜브(12)와 핀(13)을 결합시키기 위해서는 도 2에 도시된 바와 같이, 일정 면적을 가지는 핀(13)을 튜브(12)의 길이 방향으로 다수 배열시키고, 핀(13)에 형성되되 내경이 튜브(12)의 외경보다 크게 형성되는 튜브삽입공(13-1)에 튜브(12)를 삽입한 후, 튜브(12)의 외경 확장에 의해 튜브(12)와 핀(13)을 결합시킬 수 있다.In order to couple the tube 12 and the fin 13 by a mechanical method, as shown in FIG. 2, a plurality of fins 13 having a certain area are arranged in the length direction of the tube 12, and the fins 13 After inserting the tube 12 into the tube insertion hole 13-1, which is formed in the tube 12, but the inner diameter is larger than the outer diameter of the tube 12, the tube 12 and the pin ( 13) can be combined.

상술된 기계적인 방식에 의해 튜브(12)와 핀(13)을 결합시키는 열교환기는 브레이징을 통해 튜브(12)와 핀(13)을 결합시키는 방식의 열교환기에 비해 제조 원가가 절감되는 장점이 있다.A heat exchanger that combines the tube 12 and the fin 13 by the mechanical method described above has an advantage of reducing manufacturing cost compared to a heat exchanger of a method of combining the tube 12 and the fin 13 through brazing.

그러나 기계적인 방식을 통해 튜브(12)와 핀(13)을 결합시키는 방식은 단순 접촉에 의해 결합되므로, 이에 따른 열 저항에 의해 브레이징 방식의 열교환기에 비해 열전도 효율이 낮은 문제점이 있다.However, since the method of coupling the tube 12 and the fin 13 through a mechanical method is coupled by simple contact, there is a problem in that the heat conduction efficiency is lower than that of the brazing type heat exchanger due to thermal resistance.

또한, 브레이징 방식에 비해 튜브(12)와 핀(13)과의 고른 접촉 불량에 따라 열전도 효율이 낮은 문제점이 있다.In addition, compared to the brazing method, there is a problem in that the heat conduction efficiency is low due to poor even contact between the tube 12 and the fin 13.

이하, 상술한 바와 같은 본 발명에 따른 열교환기를 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, a heat exchanger according to the present invention as described above will be described in detail with reference to the accompanying drawings.

도 3 내지 도 4는 본 발명에 따른 열교환기를 나타낸 도면이다.3 to 4 are views showing a heat exchanger according to the present invention.

도 3 내지 도 4에 도시된 바와 같이, 본 발명에 따른 열교환기(1000)는 튜브(100), 핀(200) 및 헤더탱크(300)를 포함하여 형성된다.3 to 4, the heat exchanger 1000 according to the present invention is formed including a tube 100, a fin 200 and a header tank 300.

튜브(100)는 내부에 열교환매체가 유동 가능하게 형성되는 유로가 형성되며, 기계적인 방식에 의해 외경이 확장 가능하게 형성된다.The tube 100 has a flow path formed therein to allow the heat exchange medium to flow, and the outer diameter thereof is formed to be expandable by a mechanical method.

이를 위해, 튜브(100)는 열교환매체의 유동 및 누수가 방지될 수 있는 재질로 형성됨과 더불어, 유연한 재질로 형성됨으로써, 튜브(100)의 외경 확장을 위한 장치가 삽입되어 외경의 확장이 용이하도록 하는 것이 바람직하다.To this end, the tube 100 is formed of a material that can prevent flow and leakage of the heat exchange medium, and is formed of a flexible material, so that a device for expanding the outer diameter of the tube 100 is inserted to facilitate expansion of the outer diameter. It is desirable to do.

핀(200)은 튜브(100)가 삽입 가능하게 형성되는 튜브삽입공(210)이 다수 형성되며, 튜브(100)의 길이 방향으로 선택되는 길이만큼 다수 배열되어 위치될 수 있다.The fin 200 has a plurality of tube insertion holes 210 formed to allow the tube 100 to be inserted, and may be arranged and positioned as many as a length selected in the length direction of the tube 100.

이때, 튜브삽입공(210)은 튜브(100)가 삽입 가능할 뿐만 아니라, 튜브(100)의 외경 확장 시, 튜브삽입공(210)의 내면과 튜브(100)의 외면이 서로 접촉되어 결합되어야 하므로, 튜브삽입공(210)의 내경은 튜브(100)의 외경보다는 약간 크게 형성되는 것이 바람직하다.At this time, the tube insertion hole 210 is not only the tube 100 can be inserted, but when the outer diameter of the tube 100 is expanded, the inner surface of the tube insertion hole 210 and the outer surface of the tube 100 must be in contact with each other to be coupled. , The inner diameter of the tube insertion hole 210 is preferably formed slightly larger than the outer diameter of the tube (100).

즉, 본 발명에 따른 열교환기(1000)는 튜브(100)가 튜브삽입공(210)에 삽입되고, 삽입된 튜브(100)를 기계적인 방식에 의해 외경을 확장시킴으로써, 튜브(100)의 외면과 튜브삽입공(210)의 내면을 서로 접촉시켜 결합할 수 있다.That is, in the heat exchanger 1000 according to the present invention, the tube 100 is inserted into the tube insertion hole 210, and the inserted tube 100 is expanded by a mechanical method, thereby increasing the outer surface of the tube 100 And the inner surface of the tube insertion hole 210 may be brought into contact with each other to be coupled.

아울러, 본 발명에 따른 열교환기(1000)는 배열된 핀(200)의 양단이 결합되어 핀(200)을 고정시킬 수 있는 별도의 고정수단을 더 포함할 수 있으나, 한정하지는 않는다.In addition, the heat exchanger 1000 according to the present invention may further include a separate fixing means capable of fixing the fins 200 by coupling both ends of the arranged fins 200, but is not limited thereto.

헤더탱크(300)는 열교환매체가 유입 및 배출되는 입구파이프(310) 및 출구파이프(320)를 포함하며, 서로 이격되어 튜브(100)의 양단이 결합되도록 한 쌍으로 형성된다.The header tank 300 includes an inlet pipe 310 and an outlet pipe 320 through which a heat exchange medium is introduced and discharged, and is spaced apart from each other and formed in a pair so that both ends of the tube 100 are coupled.

상술된 바와 같이, 본 발명에 따른 열교환기(1000)는 엔진 등에서 유입되는 열교환매체가 입구파이프(310)를 통해 헤더탱크(300)로 유동하고, 양단이 결합된 튜브(100)를 따라 이동하여 출구파이프(320)를 통해 배출되며, 튜브(100)와 결합된 핀(200)을 통해 주행풍 등에 의해 유동하는 공기와 열 교환되도록 함으로써, 열교환매체를 냉각시킬 수 있다.As described above, in the heat exchanger 1000 according to the present invention, the heat exchange medium introduced from the engine, etc. flows to the header tank 300 through the inlet pipe 310, and moves along the tube 100 to which both ends are combined. The heat exchange medium can be cooled by allowing heat exchange with air that is discharged through the outlet pipe 320 and flows by running wind or the like through the fin 200 coupled to the tube 100.

이는 튜브(100)와 핀(200)을 브레이징을 통해 결합하는 열교환기에 비해, 열교환기의 제작에 따른 브레이징 과정을 생략할 수 있으므로, 제조 원가를 절감할 수 있는 장점이 있다.Compared to a heat exchanger in which the tube 100 and the fin 200 are coupled through brazing, the brazing process according to the manufacture of the heat exchanger can be omitted, thereby reducing manufacturing cost.

<제1 실시예><First Example>

도 5는 본 발명의 제1 실시예에 따른 열교환기의 핀과 튜브를 나타낸 도면이다.5 is a view showing fins and tubes of a heat exchanger according to a first embodiment of the present invention.

이때, 도 5의 (a)는 튜브(100)의 외경 확장 전, 도 5의 (b)는 튜브(100)의 외경 확장 후를 나타낸 도면이다.At this time, Figure 5 (a) is a view showing the expansion of the outer diameter of the tube 100 before, Figure 5 (b) is a view showing the expansion of the outer diameter of the tube 100.

도 5에 도시된 바와 같이, 본 발명의 제1 실시예에 따른 열교환기(1000)는 핀(200)에 형성된 튜브삽입공(210)의 내면이 요철 형상으로 형성된다.As shown in FIG. 5, in the heat exchanger 1000 according to the first embodiment of the present invention, the inner surface of the tube insertion hole 210 formed in the fin 200 is formed in an uneven shape.

즉, 튜브삽입공(210)은 내면이 절곡된 요철 형상으로 형성됨으로써, 튜브(100)의 외경 확장에 따른 튜브(100)의 외면과 튜브삽입공(210)의 내면과의 접촉 면적을 증대시킬 수 있다.That is, the tube insertion hole 210 is formed in an uneven shape in which the inner surface is bent, thereby increasing the contact area between the outer surface of the tube 100 and the inner surface of the tube insertion hole 210 according to the expansion of the outer diameter of the tube 100. I can.

이는 기계식 방식에 의해 튜브(100)와 핀(200)이 단순 접촉되어 결합되는 열교환기에 있어서, 튜브(100)와 핀(200)과의 접촉 면적을 증대시킴으로써, 종래의 기계식 열교환기에 비해 튜브(100)와 핀(200)과의 열전도 성능을 향상시킬 수 있다.This is a heat exchanger in which the tube 100 and the fin 200 are simply contacted and combined by a mechanical method, and by increasing the contact area between the tube 100 and the fin 200, the tube 100 ) And the heat conduction performance between the fins 200 may be improved.

아울러, 튜브(100)는 튜브삽입공(210)의 내면에 밀착되도록 외면이 튜브삽입공(210)의 형상에 대응하는 형상으로 형성되는 것이 바람직하다.In addition, it is preferable that the outer surface of the tube 100 is formed in a shape corresponding to the shape of the tube insertion hole 210 so as to be in close contact with the inner surface of the tube insertion hole 210.

즉, 튜브(100)의 외면은 튜브삽입공(210)의 형상에 대응하도록 절곡되어 요철 형상으로 형성됨에 따라, 튜브(100)의 외경 확장에 따라 튜브삽입공(210)의 내면과 고르게 접촉하여 결합될 수 있다.That is, as the outer surface of the tube 100 is bent to correspond to the shape of the tube insertion hole 210 and formed into an uneven shape, the outer surface of the tube 100 is evenly in contact with the inner surface of the tube insertion hole 210 according to the expansion of the outer diameter of the tube 100. Can be combined.

다시 말해, 내면이 요철 형상으로 형성되는 튜브삽입공(210)과 접촉되어 결합되도록 튜브(100)의 외경을 확장할 시, 요철 형상의 튜브삽입공(210)에 고르게 접촉하기 어려운 문제점이 있으며, 고른 접촉을 위해 튜브(100)의 외경을 큰 힘을 가하여 외경을 확장할 시에, 튜브(100)의 두께 및 강성이 낮아져 파손 등에 의해 열교환매체가 누수될 수 있는 우려가 있다.In other words, when expanding the outer diameter of the tube 100 so that the inner surface is in contact with the tube insertion hole 210 formed in an uneven shape, there is a problem that it is difficult to evenly contact the tube insertion hole 210 having an uneven shape, When expanding the outer diameter by applying a large force to the outer diameter of the tube 100 for even contact, the thickness and rigidity of the tube 100 are lowered, and there is a concern that the heat exchange medium may leak due to damage or the like.

이를 위해, 튜브(100)의 외면을 튜브삽입공(210)의 내면 형상과 대응하는 요철 형상으로 형성함으로써, 튜브(100)의 외경 확장에 따른 튜브(100)의 파손을 방지함과 더불어, 튜브삽입공(210)의 내면과 고르게 접촉 결합되도록 하는 것이 바람직하다.To this end, by forming the outer surface of the tube 100 in a concave-convex shape corresponding to the inner surface shape of the tube insertion hole 210, while preventing damage to the tube 100 due to the expansion of the outer diameter of the tube 100, the tube It is preferable to make contact coupling with the inner surface of the insertion hole 210 evenly.

상술된 바와 같이, 본 발명의 제1 실시예에 따른 열교환기(1000)는 핀(200)에 형성되는 튜브삽입공(210)의 내면과, 튜브(100)의 외면을 절곡시켜 요철 형상으로 형성함으로써, 튜브(100)와 핀(200)과의 접촉 면적을 증대시켜 튜브(100)와 핀(200)과의 열전도 성능을 향상시킬 수 있다.As described above, the heat exchanger 1000 according to the first embodiment of the present invention is formed in an uneven shape by bending the inner surface of the tube insertion hole 210 formed in the fin 200 and the outer surface of the tube 100 By doing so, the contact area between the tube 100 and the fin 200 may be increased, thereby improving heat conduction performance between the tube 100 and the fin 200.

또한, 본 발명의 제1 실시예에 따른 열교환기(1000)는 선택되는 크기를 가지는 튜브삽입공(210)과 튜브(100)의 외면을 크기의 큰 변화 없이 절곡하여 요철 형상으로 형성함으로써, 튜브삽입공(210)의 크기 및 형상의 요소가 튜브(100)와 핀(200)의 면적에 방해하지 않도록 할 수 있다.In addition, in the heat exchanger 1000 according to the first embodiment of the present invention, the tube insertion hole 210 having a selected size and the outer surface of the tube 100 are bent and formed into an uneven shape without a large change in size. The size and shape of the insertion hole 210 can be prevented from interfering with the area of the tube 100 and the fin 200.

다시 말해, 접촉 면적을 넓히기 위해 튜브삽입공과 튜브를 타원형 형상으로 형성하는 종래의 기계식 열교환기는 튜브삽입공과 튜브의 타원형 형상에 대응하는 면적 증가가 수반되어야 하며, 이는 작은 면적에 구비되기 위한 소형의 열교환기를 제작하기 불리하다.In other words, a conventional mechanical heat exchanger in which a tube insertion hole and a tube are formed in an oval shape to increase the contact area must be accompanied by an increase in area corresponding to the tube insertion hole and the elliptical shape of the tube. It is disadvantageous to make a flag.

이에 반해, 본 발명의 제1 실시예에 따른 열교환기(1000)는 튜브(100)와 핀(200)간의 접촉 면적 증대를 위한 별도의 면적을 필요로 하지 않으며, 요철 형상으로의 변경을 통해 튜브(100)와 핀(200)간의 접촉 면적을 증대시킬 수 있으므로, 소형의 열교환기에 적용이 유리할 뿐만 아니라, 종래의 기계식 열교환기에 비해 열 교환 성능이 향상된 열교환기를 제작할 수 있다.In contrast, the heat exchanger 1000 according to the first embodiment of the present invention does not require a separate area for increasing the contact area between the tube 100 and the fin 200, and the tube is Since the contact area between the (100) and the fins (200) can be increased, it is not only advantageous in application to a small heat exchanger, but also a heat exchanger having improved heat exchange performance compared to a conventional mechanical heat exchanger can be manufactured.

<제2 실시예><Second Example>

도 6은 본 발명의 제2 실시예에 따른 열교환기의 핀과 튜브를 나타낸 도면이다.6 is a view showing fins and tubes of a heat exchanger according to a second embodiment of the present invention.

이때, 도 6의 (a)는 튜브(100)의 외경 확장 전, 도 6의 (b)는 튜브(100)의 외경 확장 후를 나타낸 도면이다.At this time, Figure 6 (a) is a view showing the expansion of the outer diameter of the tube 100 before, and Figure 6 (b) is a view showing the expansion of the outer diameter of the tube 100.

도 6에 도시된 바와 같이, 본 발명의 제2 실시예에 따른 열교환기(1000)의 튜브관통공(210)은 원주면으로부터 수평하게 일정 길이를 가지도록 관통되어 형성되는 연장관통공(211)을 적어도 하나 이상 포함한다.As shown in Fig. 6, the tube through hole 210 of the heat exchanger 1000 according to the second embodiment of the present invention has an extended through hole 211 formed by passing through it to have a predetermined length horizontally from the circumferential surface. It contains at least one or more.

아울러, 튜브(100)는 연장관통공(211)에 대응하여 외면으로 일정 길이를 가지도록 돌출되어 형성되는 돌출부(110)를 포함한다.In addition, the tube 100 includes a protrusion 110 formed to protrude to have a predetermined length to an outer surface corresponding to the extension through hole 211.

즉, 튜브삽입공(210)은 연장관통공(211)을 포함하고, 튜브(100)의 외면에는 돌출부(110)가 형성됨에 따라, 튜브(100)의 외경 확장에 따른 돌출부(110)가 연장관통공(211)에 삽입되어 접촉됨으로써, 튜브(100)와 핀(200)과의 접촉 면적을 증대 시킬 수 있다.That is, the tube insertion hole 210 includes an extension through hole 211, and as the protrusion 110 is formed on the outer surface of the tube 100, the protrusion 110 according to the outer diameter expansion of the tube 100 is extended through hole The contact area between the tube 100 and the fin 200 may be increased by being inserted into and contacting the 211.

이는 튜브(100)의 확장에 따른 기계식 방식에 의해 튜브(100)와 핀(200)이 단순 접촉되어 결합되는 열교환기에 있어서, 튜브(100)와 핀(200)과의 접촉 면적을 증대시킴으로써, 종래의 기계식 열교환기에 비해 튜브(100)와 핀(200)과의 열전도 성능을 향상시킬 수 있다.This is a heat exchanger in which the tube 100 and the fin 200 are simply contacted and combined by a mechanical method according to the expansion of the tube 100, by increasing the contact area between the tube 100 and the fin 200, Compared to the mechanical heat exchanger of, the heat conduction performance between the tube 100 and the fin 200 may be improved.

이때, 튜브(100)에 형성된 돌출부(110)의 폭은 연장관통공(211)의 폭과 동일하게 형성함으로써, 튜브(100)의 외경 확장에 따라 돌출부(110)와 연장관통공(211)과의 접촉 확률을 증대시키는 것이 바람직하다.At this time, the width of the protrusion 110 formed in the tube 100 is formed equal to the width of the extension through hole 211, so that the contact between the protrusion 110 and the extension through hole 211 according to the expansion of the outer diameter of the tube 100 It is desirable to increase the probability.

반면, 튜브(100)에 형성된 돌출부(110)의 길이는 연장관통공(211)의 길이보다 동일하거나 작게 형성하는 것이 바람직하다.On the other hand, the length of the protrusion 110 formed in the tube 100 is preferably formed equal to or smaller than the length of the extension through hole 211.

좀 더 상세하게 설명하자면, 돌출부(110)는 연장관통공(210)의 길이와 동일하게 형성됨에 따라, 튜브(100)의 외경 확장 시, 연장관통공(210)에 돌출부(110)가 삽입되어 접촉되므로, 튜브(100)와 핀(200)과의 접촉 면적을 증대시켜 튜브(100)와 핀(200)간의 열전도 성능을 향상시킬 수 있다.In more detail, as the protrusion 110 is formed equal to the length of the extension through hole 210, when the outer diameter of the tube 100 is expanded, the protrusion 110 is inserted into the extension through hole 210 to contact , By increasing the contact area between the tube 100 and the fin 200, the heat conduction performance between the tube 100 and the fin 200 may be improved.

상술된 바와 같이, 본 발명에 따른 열교환기(1000)는 튜브(100)의 확장에 따라 핀(200)과 결합되는 열교환기를 형성할 수 있으므로, 튜브와 핀을 브레이징하여 결합하는 열교환기에 비해 제조 원가를 절감시킬 수 있을 뿐만 아니라, 튜브(100)와 핀(200)과의 접촉 면적 증대에 따른 튜브(100)와 핀(200)과의 열전도 성능을 향상시킬 수 있으므로, 종래의 튜브에 확장에 따른 튜브와 핀을 결합하는 기계식 열교환기에 비해 열전도 성능 및 이에 대응하는 열 교환 성능을 향상시킬 수 있다.As described above, since the heat exchanger 1000 according to the present invention can form a heat exchanger that is coupled with the fins 200 according to the expansion of the tube 100, manufacturing cost compared to a heat exchanger that combines the tubes and fins by brazing In addition to being able to reduce the heat conduction performance between the tube 100 and the fin 200 according to the increase in the contact area between the tube 100 and the fin 200, it is possible to improve the Compared to a mechanical heat exchanger that combines a tube and a fin, it is possible to improve heat conduction performance and corresponding heat exchange performance.

본 발명은 상기한 실시예에 한정되지 않으며, 적용범위가 다양함은 물론이고, 청구범위에서 청구하는 본 발명의 요지를 벗어남 없이 다양한 변형 실시예가 가능함은 물론이다.It goes without saying that the present invention is not limited to the above-described embodiments, and the scope of application is various, and various modified embodiments are possible without departing from the gist of the present invention claimed in the claims.
