The present invention relates to a heat exchanger comprising: a header in which a plurality of groove portions concavely recessed from the end are formed between bent tabs formed spaced apart from each other along the circumference; and a tank which is coupled to the header, thereby forming a space for a heat exchange medium to flow, wherein the lower end of the tank is inserted into the header, and the bent tabs are bent inward and coupled to the tank. A first groove portion deeper than the groove portions is formed in the header. Accordingly, thermal deformation caused by a difference in temperature is easily permitted, thus reducing thermal stress and thereby preventing leakage of the heat exchange medium.
Description
본 발명은 두 개의 열교환부가 일체로 형성된 열교환기에 관한 것이다.The present invention relates to a heat exchanger in which two heat exchange units are integrally formed.
일반적으로 열교환기는 특정 유로상에 설치되어 그 내부를 순환하는 열교환매체가 외기열을 흡열하거나 또는 열교환매체의 열을 외부로 방열하는 방식으로 열교환을 수행하는 장치이다.In general, a heat exchanger is a device that is installed on a specific flow path and performs heat exchange in such a way that a heat exchange medium circulating therein absorbs heat from outside air or dissipates heat from the heat exchange medium to the outside.
이러한 열교환기는 냉매를 열교환매체로 사용하는 응축기와 증발기, 그리고 냉각수를 열교환매체로 사용하는 라디에이터와 히터코어, 또한 엔진 및 변속기 등의 내부를 유동하는 오일을 냉각하기 위해 오일을 열교환매체로 사용하는 오일쿨러 등 사용목적과 용도에 따라 다양하게 제작되고 있다.These heat exchangers include condensers and evaporators that use refrigerant as a heat exchange medium, radiators and heater cores that use coolant as a heat exchange medium, and oil that uses oil as a heat exchange medium to cool oil flowing inside engines and transmissions. Coolers are manufactured in various ways according to the purpose and purpose of use.
그리고 근래 자동차 산업에 있어서 세계적으로 환경과 에너지에 대한 관심이 높아짐에 따라 연비 개선을 위한 연구가 이루어지고 있으며, 다양한 소비자의 요구를 만족시키기 위해 경량화ㆍ소형화 및 고기능화를 위한 연구개발이 꾸준히 이루어지고 있다.In recent years, as interest in the environment and energy has increased globally in the automobile industry, research to improve fuel efficiency has been conducted, and research and development for light weight, compact size, and high functionality have been steadily conducted to satisfy various consumer needs. .
그런데 자동차에 사용되는 열교환기에 있어서 복수의 열교환기를 별개로 제작하여 설치하는 경우 제작공수가 많아져 생산성이 낮을 뿐만 아니라, 재료의 낭비가 심해 원가 상승과 더불어 각각의 열교환기들을 장착하기 위한 공간을 확보하는 데에도 어려움이 있었다. 그리하여 이러한 문제를 해결하기 위해 복수의 열교환기를 일체화하여 형성하는 다양한 기술이 개발되어 사용되고 있다.However, in the heat exchanger used in automobiles, when a plurality of heat exchangers are separately manufactured and installed, the number of manufacturing man-hours increases, resulting in low productivity, as well as a significant waste of materials, which increases cost and secures space for mounting each heat exchanger. I also had difficulty doing it. Therefore, in order to solve this problem, various technologies for integrating and forming a plurality of heat exchangers have been developed and used.
이와 관련된 종래 기술로 한국공개특허(10-2007-0081635)인 일체형 열교환기가 개시되어 있으며, 도 1은 종래의 일체형 열교환기를 나타낸 도면이다.As a prior art related to this, an integrated heat exchanger of Korean Patent Publication (10-2007-0081635) is disclosed, and FIG. 1 is a view showing a conventional integrated heat exchanger.
도시된 바와 같이 종래의 일체형 열교환기는 제1유체가 유통되는 복수개의 제1튜브(11), 상기 제1튜브(11)의 사이에 개재되어진 제1방열핀(12) 및 상기 제1튜브(11)의 양단에 각각 결합되는 제1헤더(13)로 이루어진 제1코어부(10)와, 제2유체가 유통되는 복수개의 제2튜브(21), 상기 제2튜브(21)의 사이에 개재되어진 제2방열핀(22) 및 상기 제2튜브(21)의 양단에 각각 결합되는 제2헤더(23)로 이루어진 제2코어부(20)와, 상하로 배열되는 상기 제1,2코어부(10)(20)의 제1헤더(12) 및 제2헤더(22)에 동시에 결합되어 상기 제1,2유체가 유동되는 공간을 형성하는 단일의 탱크(30)와, 상기 탱크(30)의 내부에 적어도 하나 이상 설치되어 제1유체와 제2유체를 분리하는 배플(60)을 포함하여 이루어진다. 이와 같이 종래의 일체형 열교환기는 단일 탱크(30) 내부를 배플(60)로 구획하여 두 가지 열교환매체를 동시에 냉각시킬 수 있도록 하였다.As shown, the conventional integrated heat exchanger includes a plurality of first tubes 11 through which a first fluid flows, a first heat dissipation fin 12 interposed between the first tubes 11, and the first tube 11 Interposed between the first core part 10 consisting of the first header 13 coupled to both ends of the , a plurality of second tubes 21 through which the second fluid circulates, and the second tube 21 The second core part 20 composed of the second header 23 coupled to both ends of the second heat dissipation fin 22 and the second tube 21, respectively, and the first and second core parts 10 arranged vertically A single tank 30 coupled to the first header 12 and the second header 22 of the ) 20 at the same time to form a space in which the first and second fluids flow, and the inside of the tank 30 At least one is installed on the baffle 60 to separate the first fluid and the second fluid. As described above, the conventional integrated heat exchanger partitions the inside of a single tank 30 with baffles 60 so that two heat exchange media can be cooled simultaneously.
그런데 이때 일체형 열교환기는 온도가 다른 두 가지의 열교환매체가 배플(60)로 구획된 하나의 탱크 내부를 순환하게 되므로, 온도차에 의한 튜브(21,22)와 탱크(60)의 열팽창 차이에 의해 튜브, 헤더 및 탱크의 변형이 발생하게 되고 이로 인해 열교환매체의 누설이 발생할 수 있다. 이를 해결하기 위해 서로 이격되어 배치된 한 쌍의 배플(60)을 탱크(30)에 설치하고, 한 쌍의 배플(60) 사이에 열차단 슬롯(31)을 형성하여 탱크(30)를 통한 두 가지 열교환매체의 열전달을 줄일 수 있도록 하였으나, 일체형 열교환기는 가열과 냉각이 반복되며 두 개의 열교환부가 접하는 부분에서 충분한 응력 흡수가 어려워, 여전히 열교환매체의 누설이 발생할 수 있는 문제점이 있다.However, at this time, since the integrated heat exchanger circulates the inside of one tank partitioned by the baffle 60 in two heat exchange media having different temperatures, the difference in thermal expansion between the tubes 21 and 22 and the tank 60 due to the temperature difference causes the tubes to circulate. , deformation of the header and tank may occur, which may cause leakage of the heat exchange medium. In order to solve this problem, a pair of baffles 60 disposed apart from each other are installed in the tank 30, and a heat shielding slot 31 is formed between the pair of baffles 60 so that the two through the tank 30 Although it is possible to reduce the heat transfer of the heat exchange medium, the integrated heat exchanger repeatedly heats and cools, and it is difficult to absorb sufficient stress at the part where the two heat exchange parts come into contact, so there is still a problem that leakage of the heat exchange medium may occur.

이에 따라 한 쌍의 배플(111, 211)에 의해 제1헤더탱크(100) 및 제2헤더탱크(200)의 내부 공간이 각각 구획되며, 한 쌍의 배플(111, 211)이 형성된 위치를 기준으로 길이방향으로 좌측에는 제1열교환부(1001)가 형성되고 우측에는 제2열교환부(1002)가 형성될 수 있다. 그리고 제1열교환부(1001)와 제2열교환부(1002)에는 각각 입구 파이프와 출구 파이프가 형성되어, 제1열교환부(1001)의 내부와 제2열교환부(1002)의 내부에 서로 다른 열교환매체가 유동될 수 있다. 또한, 열교환매체는 냉각수이며, 본 발명의 열교환기는 라디에이터로서 서로 온도가 상이한 저온 및 고온의 열교환매체가 배플에 의해 구획된 일측과 타측에 각각 유동되는 일체형 라디에이터일 수 있다.Accordingly, the inner spaces of the first header tank 100 and the second header tank 200 are partitioned by the pair of baffles 111 and 211, respectively, and the positions where the pair of baffles 111 and 211 are formed are referenced. In the longitudinal direction, the first heat exchange unit 1001 may be formed on the left side and the second heat exchange unit 1002 may be formed on the right side in the longitudinal direction. In addition, an inlet pipe and an outlet pipe are formed in the first heat exchange unit 1001 and the second heat exchange unit 1002, respectively, so that the inside of the first heat exchange unit 1001 and the inside of the second heat exchange unit 1002 exchange different heat.

여기에서 제1헤더탱크(100) 및 제2헤더탱크(200) 각각의 헤더(130, 230)에는 길이방향으로 한 쌍의 배플(111, 211)의 사이에 대응되는 위치에 홈부(131)들 보다 깊이가 깊은 제1홈부(133)가 형성될 수 있다. 제1헤더탱크(100)를 예를 들어 설명하면, 길이방향으로 한 쌍의 배플(111) 사이의 위치는 제1열교환부(1001)와 제2열교환부(1002)가 서로 만나는 부분이며, 이 부분에서는 양측 열교환부의 온도차에 의해 양측 열교환부에 위치하는 튜브(300)들의 열팽창에 따른 길이변화가 달라서, 헤더에 열변형이 발생하게 된다. 이때, 본 발명은 헤더(130)에 형성된 제1홈부(133)가 헤더(130)의 열변형을 쉽게 허용하는 구조를 만들어주기 때문에, 헤더탱크의 제1열교환부(1001)와 제2열교환부(1002)의 사이 위치에서 헤더(130) 및 이 부분에 인접한 튜브(300)가 헤더(130)에 결합된 부분에 발생하는 열응력을 줄일 수 있다. 따라서 양측 열교환부의 온도차에 의해 발생하는 열응력에 따른 헤더, 헤더와 튜브의 결합부분의 파손을 방지할 수 있게 되며, 이에 따라 일체형 열교환기의 신뢰성이 향상될 수 있다.Here, in the headers 130 and 230 of the first header tank 100 and the second header tank 200, respectively, grooves 131 are provided at positions corresponding to the positions between the pair of baffles 111 and 211 in the longitudinal direction. A deeper first groove 133 may be formed. Taking the first header tank 100 as an example, the position between the pair of baffles 111 in the longitudinal direction is the part where the first heat exchange part 1001 and the second heat exchange part 1002 meet each other, and this In this part, the length change according to the thermal expansion of the tubes 300 located on both sides of the heat exchange part is different due to the temperature difference of the heat exchange part on both sides, so that the header is thermally deformed. At this time, in the present invention, since the first groove 133 formed in the header 130 creates a structure that easily allows thermal deformation of the header 130, the first heat exchange part 1001 and the second heat exchange part of the header tank Thermal stress occurring at a portion between the header 130 and the portion where the tube 300 adjacent to the header 130 is coupled to the header 130 may be reduced. Therefore, it is possible to prevent damage to the header and the coupling portion between the header and the tube due to thermal stress generated by the temperature difference between the two heat exchange units, and thus the reliability of the integrated heat exchanger can be improved.
또한, 본 발명의 열교환기는 더미튜브(310)를 더 포함하여 구성될 수 있다. 더미튜브(310)는 길이방향으로 한 쌍의 배플(111, 211) 사이의 위치에 배치될 수 있으며, 더미튜브(310)는 튜브(300)들과 마찬가지로 제1헤더탱크(100) 및 제2헤더탱크(200)에 양단이 연결된 형태로 결합될 수 있다. 여기에서 더미튜브(310)는 내부가 비어있고 내부에 열교환매체가 유동되지 않으며, 더미튜브(310)는 제1열교환부(1001)와 제2열교환부(1002) 간의 열전달을 차단하는 역할을 할 수 있다. 그리고 더미튜브(310)는 일례로 튜브(300)들과 동일한 형태로 형성되어, 튜브(300)와 더미튜브(310)를 공용으로 용이하게 사용할 수 있다. 또한, 더미튜브(310)의 양측에 인접한 튜브(300) 사이의 위치에 제1홈부(133)가 형성될 수 있으며, 바람직하게는 길이방향으로 더미튜브(310)에 대응되는 위치에 제1홈부(133)가 형성될 수 있다. In addition, the heat exchanger of the present invention may be configured to further include a dummy tube 310. The dummy tube 310 may be disposed at a position between the pair of baffles 111 and 211 in the longitudinal direction, and like the tubes 300, the dummy tube 310 is connected to the first header tank 100 and the second header tank 100. Both ends may be coupled to the header tank 200 in a connected form. Here, the dummy tube 310 has an empty interior and no heat exchange medium flows therein, and the dummy tube 310 serves to block heat transfer between the first heat exchange unit 1001 and the second heat exchange unit 1002. can In addition, the dummy tube 310 is formed in the same shape as the tubes 300, for example, so that the tube 300 and the dummy tube 310 can be easily used in common. In addition, the first groove 133 may be formed at a position between the tubes 300 adjacent to both sides of the dummy tube 310, and preferably at a position corresponding to the dummy tube 310 in the longitudinal direction. (133) may be formed.
또한, 제1홈부(133)는 헤더(130)의 폭방향 양측에 서로 대응되는 위치에 형성되어, 보다 용이하게 헤더(130)가 열변형을 허용하도록 할 수 있다.In addition, the first grooves 133 are formed at positions corresponding to each other on both sides of the header 130 in the width direction, so that the header 130 can more easily tolerate thermal deformation.
도 7 및 도 8은 본 발명의 제2실시예에 따른 열교환기의 헤더의 일부를 나타낸 사시도 및 정면도이다.7 and 8 are a perspective view and a front view showing a part of a header of a heat exchanger according to a second embodiment of the present invention.
도시된 바와 같이 본 발명의 제2실시예에 따른 열교환기의 한 쌍의 헤더탱크(100, 200)는 각각의 헤더에 제2홈부(134)가 더 형성될 수 있다. 일례로 제1헤더탱크(100)의 헤더(130)에는 길이방향으로 제1홈부(133)의 일측 또는 양측에 이격되어 제2홈부(134)가 형성되고, 제2홈부(134)는 홈부(131)들 보다 깊이가 깊게 형성될 수 있다. 즉, 제1홈부(133)에 인접하여 제2홈부(134)가 추가로 형성되는 것이다. 이때, 제2홈부(134)의 깊이는 제1홈부(133)와 동일하게 형성될 수 있다.As shown, in the pair of header tanks 100 and 200 of the heat exchanger according to the second embodiment of the present invention, a second groove 134 may be further formed in each header. For example, the header 130 of the first header tank 100 is formed with a second groove 134 spaced apart from one side or both sides of the first groove 133 in the longitudinal direction, and the second groove 134 is a groove ( 131) may be formed deeper. That is, the second groove 134 is additionally formed adjacent to the first groove 133 . In this case, the second groove 134 may have the same depth as the first groove 133 .
그리하여 제1홈부(133)가 형성된 부분을 기준으로 길이방향 바깥쪽으로 가면서 분산시켜 열변형을 허용하도록(열응력을 감소시키도록) 함으로써, 헤더 및 헤더와 튜브가 결합된 부분의 파손을 더욱 효과적으로 방지할 수 있다.Therefore, by distributing the first groove portion 133 outward in the longitudinal direction based on the formed portion to allow thermal deformation (to reduce thermal stress), damage to the header and the portion where the header and the tube are combined is more effectively prevented can do.
도 9 및 도 10은 본 발명의 제3실시예에 따른 열교환기의 헤더의 일부를 나타낸 사시도 및 정면도이다.9 and 10 are a perspective view and a front view showing a part of a header of a heat exchanger according to a third embodiment of the present invention.
도시된 바와 같이 본 발명의 제3실시예에 따른 열교환기의 한 쌍의 헤더탱크(100, 200)는 각각의 헤더에 제3홈부(135)가 더 형성될 수 있다. 일례로 제1헤더탱크(100)의 헤더(130)에는 길이방향으로 제1홈부(133)의 일측 또는 양측에 이격되어 제3홈부(135)가 형성되고, 제3홈부(135)는 홈부(131)들 보다 깊이가 깊게 형성될 수 있다. 즉, 제1홈부(133)에 인접하여 제3홈부(135)가 추가로 형성되는 것이다. 이때, 제3홈부(135)의 깊이는 제1홈부(133) 보다는 깊이가 얕게 형성될 수 있다. 다시말하면, 제1홈부(133)의 깊이가 제일 깊게 형성되고 제1홈부(133)를 기준으로 길이방향 바깥쪽으로 가면서 깊이가 덜 깊은 제3홈부(135)가 형성되고 그 다음에 제3홈부(135) 보다 깊이가 덜 깊은 홈부(131)가 형성된 형태로 배치될 수 있다.As shown, in the pair of header tanks 100 and 200 of the heat exchanger according to the third embodiment of the present invention, a third groove 135 may be further formed in each header. For example, the header 130 of the first header tank 100 has a third groove 135 spaced apart from one side or both sides of the first groove 133 in the longitudinal direction, and the third groove 135 is a groove ( 131) may be formed deeper. That is, the third groove 135 is additionally formed adjacent to the first groove 133 . At this time, the depth of the third groove portion 135 may be formed shallower than that of the first groove portion 133 . In other words, the depth of the first groove 133 is the deepest, and the third groove 135 is formed with a less depth while going outward in the longitudinal direction based on the first groove 133, and then the third groove ( 135) may be disposed in a form in which a groove 131 having a depth less than that is formed.
그리하여 제1홈부(133)가 형성된 부분을 기준으로 길이방향 바깥쪽으로 가면서 분산시켜 단계적으로 열변형을 허용하도록(열응력을 감소시키도록) 함으로써, 헤더 및 헤더와 튜브가 결합된 부분의 파손을 더욱 효과적으로 방지할 수 있다.Thus, by dispersing the portion where the first groove portion 133 is formed while going outward in the longitudinal direction, stepwise thermal deformation is allowed (to reduce thermal stress), thereby further preventing damage to the header and the portion where the header and the tube are coupled. can be effectively prevented.
또한, 제1홈부(133)는 길이방향으로 한 쌍의 브리지(122) 사이에 위치할 수 있다. 또한, 홈부(131)들의 오목한 골의 끝을 연장한 선을 홈부 기준선이라 하면, 홈부 기준선은 탱크(110)와 가스켓(120)의 접촉면의 연장선(L)보다 헤더(130)의 바닥면으로부터 더 이격되어 배치될 수 있다. 또한, 제1홈부(133)의 오목한 골의 끝을 연장한 선을 제1홈부 기준선이라 하면, 제1홈부 기준선은 탱크(110)와 가스켓(120)의 접촉면의 연장선(L)보다 헤더(130)의 바닥면에 더 인접하게 위치할 수 있다. 또한, 제3홈부(135)의 오목한 골의 끝을 연장한 선을 제3홈부 기준선이라 하면, 제3홈부 기준선은 탱크(110)와 가스켓(120)의 접촉면의 연장선(L)보다 헤더(130)의 바닥면으로부터 더 이격되거나 동일선상에 위치할 수 있다. 즉, 일반적으로 홈부(131)는 가스켓(120)이 보이지 않는 깊이로 형성되어야 리크를 방지할 수 있으나, 제1홈부(133)는 가스켓(120)이 보이더라도 열교환매체가 흐르지 않는 더미튜브(310)에 인접한 위치에 배치되었을 경우 열교환매체의 리크가 발생할 여지가 없다. 따라서 그만큼 제1홈부(133)의 깊이를 깊게 형성할 수도 있다. 하지만 반드시 가스켓(120)이 보이게 제1홈부(133)의 깊이를 형성해야 하는 것은 아니며, 제1홈부(133)의 형성 깊이는 탱크(110)의 결합부(112) 및 가스켓(120)과 무관하게 자유롭게 형성할 수 있다.In addition, the first groove portion 133 may be located between the pair of bridges 122 in the longitudinal direction. In addition, if a line extending from the end of the concave valley of the grooves 131 is referred to as the groove reference line, the groove reference line is further from the bottom surface of the header 130 than the extension line L of the contact surface between the tank 110 and the gasket 120. They can be spaced apart. In addition, if the line extending the end of the concave valley of the first groove 133 is the first groove reference line, the first groove reference line is longer than the extension line L of the contact surface between the tank 110 and the gasket 120, the header 130 ) may be located closer to the bottom surface of the In addition, if the line extending the end of the concave valley of the third groove 135 is the third groove reference line, the third groove reference line is longer than the extension line L of the contact surface between the tank 110 and the gasket 120, the header 130 ) may be further spaced apart from the bottom surface or located on the same line. That is, in general, the groove 131 must be formed at a depth where the gasket 120 is not visible to prevent leakage, but the first groove 133 is a dummy tube 310 through which the heat exchange medium does not flow even when the gasket 120 is visible. ), there is no room for leakage of the heat exchanging medium. Accordingly, the depth of the first groove 133 may be formed as much as that. However, it is not necessary to form the depth of the first groove 133 so that the gasket 120 can be seen, and the depth of the first groove 133 is independent of the coupling part 112 of the tank 110 and the gasket 120. can be formed freely.
