일반적으로, 자동차의 엔진룸에는 라디에이터, 응축기 등의 열교환기가 탑재된다.Generally, heat exchangers, such as a radiator and a condenser, are mounted in the engine room of an automobile.
라디에이터, 응축기는 각각 단품으로 제조된 후 대개 응축기가 라디에이터에 조립된 상태에서 라디에이터가 차체에 설치된다.The radiator and condenser are each manufactured separately, and the radiator is usually installed in the vehicle body with the condenser assembled on the radiator.
이 라디에이터는, 내부에 냉각수 유로가 형성된 상하 탱크부와, 상하 탱크부를 연결하며 내부를 따라 냉각수가 흐르는 복수의 냉각수튜브와, 냉각수튜브들 사이에 설치되어 냉각수튜브들 사이를 흐르는 공기와 열교환하여 냉각수를 냉각하는 코루게이트핀으로 구성된다.The radiator is connected to the upper and lower tanks having a coolant flow path therein, a plurality of coolant tubes connecting the upper and lower tanks and flowing coolant along the inside, and installed between the coolant tubes to exchange heat with air flowing between the coolant tubes to cool the coolant.

그리고, 응축기는, 좌우 헤더 탱크와, 헤더 탱크를 연결하는 복수의 냉매튜브와, 냉매튜브들 사이에 설치되어 냉매튜브들 사이를 통과하는 공기와 열교환하여 냉매를 응축하는 코루게이트핀으로 구성된다.The condenser includes a left and right header tank, a plurality of refrigerant tubes connecting the header tank, and corrugated fins installed between the refrigerant tubes to exchange heat with air passing between the refrigerant tubes to condense the refrigerant.
한편, 근래에는 생산성 향상, 장착성 향상(장착공간감소)을 목적으로 라디에이터와 응축기의 일체형 열교환기가 제안되고 있다. 일체형 열교환기는 코루게이트핀을 공유하는 사양과 튜브를 공유하는 사양 등이 있으며, 본 발명은 응축기와 라디에이터가 코루게이트핀을 공유하는 형태의 일체형 열교환기에 있어서의 공기측 일체형 열교환기용 코루게이트핀에 관한 것이다.On the other hand, in recent years, an integrated heat exchanger of a radiator and a condenser has been proposed for the purpose of improving productivity and improving mountability (reducing mounting space). The integrated heat exchanger includes a specification sharing a corrugated fin and a specification sharing a tube. The present invention relates to a corrugated fin for an air-side integrated heat exchanger in an integrated heat exchanger of a type in which a condenser and a radiator share a corrugated fin. will be.
도 1은 일체형 열교환기의 사시도로, 도시된 바와 같이, 코루게이트핀을 공유하는 일체형 열교환기는, 복수의 응축기 튜브(10) 및 라디에이터 튜브(20)가 각각 일렬로 배열되면서 튜브(10)(20)군은 전후 2열로 배열되고, 라디에이터 튜브(20)와 응축기 튜브(10)의 사이에는 하나의 코루게이트핀(30)이 전후방향으로 장착된다.1 is a perspective view of an integrated heat exchanger, as shown, the integrated heat exchanger sharing a corrugated fin, the tube 10, 20 with a plurality of condenser tube 10 and the radiator tube 20 arranged in a line, respectively ) Group is arranged in a front and rear two rows, one corrugated fin 30 is mounted in the front and rear direction between the radiator tube 20 and the condenser tube 10.
도면중 미설명부호 11은 응축기 탱크이며, 21은 라디에이터 탱크이다.In the figure, reference numeral 11 denotes a condenser tank, and 21 denotes a radiator tank.
일체형 열교환기에 있어서, 라디에이터 튜브(20)측의 고온이 응축기 튜브(10)측으로 전도되지 않도록 한 기술이 제안된 바 있으며, 그 일예로, 일본 공개실용 평02-014582호(90.1.30)로 일체형 열교환기의 코어부가 있다.In an integrated heat exchanger, a technique has been proposed in which high temperature on the radiator tube 20 side is not conducted to the condenser tube 10 side. For example, it is integrated in Japanese Laid-Open Patent Application No. 02-014582 (90.1.30). There is a core part of the heat exchanger.
도 2와 도 3에서 보이는 바와 같이, 코루게이트핀(30)은, 판상으로 이루어지면서 파형으로 벤딩된 코루게이트핀 몸체(31)와, 코루게이트핀 몸체(31)에 응축기 튜브(10) 및 라디에이터 튜브(20)와 각각 대응 형성되는 응축기측 루버군(32) 및 라디에이터측 루버군(33)으로 구성된다.As shown in FIGS. 2 and 3, the corrugated fin 30 includes a corrugated fin body 31 formed in a plate shape and bent in a wave form, and a condenser tube 10 and a radiator on the corrugated fin body 31. The condenser-side louver group 32 and the radiator-side louver group 33 formed in correspondence with the tube 20, respectively.
그리고, 라디에이터 튜브(20)에서 발열되는 고열이 코루게이트핀 몸체(31)를 통하여 응축기측 튜브(10)로 전도되지 않도록 라디에이터측 루버군(33)과 응축기측 루버군(32)의 사이에는 열전도방지용 루버(34)가 형성된다.The heat conduction is performed between the radiator side louver group 33 and the condenser side louver group 32 so that high heat generated from the radiator tube 20 is not conducted to the condenser side tube 10 through the corrugated fin body 31. The prevention louver 34 is formed.
이와 같이 구성되는 종래 기술에 따른 일체형 열교환기의 코어부에 따르면, 공기가 열전도방지용 루버(34)을 통과하면서 이 부분이 갖고 있는 열을 빼앗음으로써 라디에이터측의 고온의 열이 응축기측으로 전도되지 않도록 할 수 있다. 그러나, 이 열전도방지용 루버(34)은 응축기측 루버군(32) 및 라디에이터측 루버군(33)과 동일한 구조로 그 구조상 열전도를 막는 것보다는 공기의 흐름을 안내하는 것을 더 큰 기능으로 하고 있기 때문에 열전도효과가 미약한 단점이 있다.According to the core portion of the integrated heat exchanger according to the prior art configured as described above, air passes through the heat conduction prevention louver 34 to take away the heat contained in the portion so that the high temperature heat of the radiator side is not conducted to the condenser side. Can be. However, since the heat conduction prevention louver 34 has the same structure as the condenser side louver group 32 and the radiator side louver group 33, its structure has a greater function of guiding the flow of air than preventing thermal conduction. There is a weak heat conduction effect.
이에, 본 발명은 상기와 같은 문제점을 해소하기 위하여 발명된 것으로, 일체형 열교환기의 라디에이터의 고온의 열이 응축기로 전도되지 않도록 함과 아울러, 응축기를 통과한 공기가 원활하게 라디에이터측으로 유동할 수 있도록 한 일체형 열교환기용 코루게이트핀을 제공하려는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, so that the high temperature heat of the radiator of the integrated heat exchanger is not conducted to the condenser, and the air passing through the condenser can smoothly flow to the radiator side. It is an object to provide a corrugated fin for an integrated heat exchanger.

It is formed between the base louver group and the second heat exchanger side louver group, and at least one side corresponding to the first heat exchanger side louver group and the second heat exchanger side louver group is cut and inclined at approximately the same angle as the louver corresponding to the incision side. It characterized in that it comprises a bent gap louver.
이하, 본 발명의 바람직한 실시예를 첨부된 예시도면에 의거하여 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.
<실시예 1><Example 1>
도 4는 본 발명에 따른 코루게이트핀의 제1실시예의 사시도이며, 도 5는 이 코루게이트핀의 정면도이다.4 is a perspective view of a first embodiment of a corrugated pin according to the present invention, and FIG. 5 is a front view of the corrugated pin.
도시된 바와 같이, 본 발명에 따른 코루게이트핀(40)은, 파형으로 벤딩된 몸체(41)와, 몸체(41)의 전후 양측부에 응축기 튜브(10) 및 라디에이터 튜브(20)와 각각 대응되면서 길이방향을 따라 형성되는 응축기측 루버군(42) 및 라디에이터측 루버군(43)과, 그리고 응축기측 루버군(42)과 라디에이터측 루버군(43)의 사이에 형성되는 갭루버(44)를 구비하여 구성된다.As shown, the corrugated fin 40 according to the present invention corresponds to the body 41 bent in a corrugated form and the condenser tube 10 and the radiator tube 20 at both front and rear sides of the body 41, respectively. The gap louver 44 is formed between the condenser side louver group 42 and the radiator side louver group 43 and the condenser side louver group 42 and the radiator side louver group 43 formed along the longitudinal direction. It is configured to include.
갭루버(44)는, 도 4와 도 5에 도시된 바와 같이, 코루게이트핀 몸체(41)의 벤딩면에 그 길이방향을 따라 삼면이 절개됨으로써 형성된다.4 and 5, the gap louver 44 is formed by cutting three surfaces along the longitudinal direction of the bending surface of the corrugated pin body 41.
도 5에서 보이는 바와 같이, 갭루버(44)는 공기가 원활하게 흐르도록 경사지게 벤딩되는데, 그 각도(θ2)는 근접하는 루버(43a)의 각도(θ1)와 대략 동일하다.As shown in FIG. 5, the gap louver 44 is bent inclined so that air flows smoothly, and the angle θ2 is approximately equal to the angle θ1 of the adjacent louver 43a.
이와 같이 구성된 본 발명에 따른 일체형 열교환기용 코루게이트핀의 작용상태는 다음과 같다.The working state of the corrugated fin for an integrated heat exchanger according to the present invention configured as described above is as follows.
차량 전방으로부터 인입되는 주위공기는 응축기 튜브(10) 사이의 코루게이트핀(40)의 응축기 튜브군(42)을 통과하면서 응축기 튜브(10)를 흐르는 냉매와 열교환되며, 계속해서, 라디에이터 튜브(20) 사이의 라디에이터 튜브군(43)을 통과하면서 냉각수와 열교환된다.The ambient air drawn from the front of the vehicle exchanges heat with the refrigerant flowing through the condenser tube 10 while passing through the condenser tube group 42 of the corrugated fins 40 between the condenser tube 10, and subsequently, the radiator tube 20. Heat exchange with the cooling water while passing through the radiator tube group (43) between.
이때, 라디에이터 튜브(20)로부터 전가된 열은 코루게이트핀(40)의 갭루버(44)가 코루게이트핀몸체(41)에서 절개 형성되어 응축기 튜브(10)측으로 전도되지 못한다.At this time, the heat transferred from the radiator tube 20, the gap louver 44 of the corrugated fin 40 is cut off from the corrugated fin body 41 and cannot be conducted to the condenser tube 10 side.
그리고, 공기는 코루게이트핀(40)의 각 루버군(42)(43)에 의해 파형을 그리면서 유동하는데, 응축기측 루버군(42)을 통과한 공기는 갭루버(44)의 경사부(44a)를 따라 원활하게 라디에이터측 루버군(43)으로 이동한다.And, air flows while drawing a wave by each louver group 42 and 43 of the corrugated pin 40, and the air passing through the condenser side louver group 42 is inclined ( It moves smoothly to the radiator side louver group 43 along 44a).
<실시예 2><Example 2>
도 6은 본 발명에 따른 코루게이트핀의 제2실시예를 보인 정면도로, 도시된 바와 같이, 전체적인 구조는 제 1실시예와 유사한 구조로 이루어지며, 라디에이터측 튜브군과 응축기측 튜브군 사이의 갭루버의 구조가 다른 것이다.Figure 6 is a front view showing a second embodiment of the corrugated fin according to the present invention, as shown, the overall structure is made of a structure similar to the first embodiment, between the radiator side tube group and the condenser side tube group The gap louver has a different structure.
갭루버(44)는 코루게이트핀 몸체(41)와 연결된 중앙부의 전후 양측부가 절개되고 이 절개측이 경사지게 벤딩되어 이루어진다.The gap louver 44 is formed by cutting both front and rear sides of the central part connected to the corrugated pin body 41 and bending the inclined side.
갭루버(45)의 양측 경사부(45a)(45b)의 각도(θ2)는 근접하는 응축기측 루버(42a)의 각도(θ1) 및 라디에이터측 루버(43a)의 각도(θ3)와 각각 대략 동일하다.The angles θ2 of both inclined portions 45a and 45b of the gap louver 45 are approximately equal to the angle θ1 of the condenser side louver 42a and the angle θ3 of the radiator side louver 43a, respectively. Do.
따라서, 응축기측 루버군(42)과 라디에이터측 루버군(43) 사이의 코루게이트핀 몸체(41)에 절개 형성된 갭루버(44 또는 45)에 의해 라디에이터의 고온의 열이 응축기측으로 전도되지 않는다.Therefore, the hot heat of the radiator is not conducted to the condenser side by the gap louver 44 or 45 formed in the corrugated fin body 41 between the condenser side louver group 42 and the radiator side louver group 43.
그리고, 갭루버(44 또는 45)의 경사를 따라 응축기측 루버군(42)을 통과한 공기가 라디에이터측 루버군(43)측으로 원활하게 유동한다.And the air which passed the condenser side louver group 42 along the inclination of the gap louver 44 or 45 flows smoothly to the radiator side louver group 43 side.
이상에서 설명한 바와 같이, 본 발명에 따른 일체형 열교환기용 코루게이트핀에 의하면, 갭루버에 의해 응축기측 고온의 공기가 라디에이터측으로 전도되지 않고 차단되므로 냉각효율을 높일 수 있다.As described above, according to the corrugated fin for integrated heat exchanger according to the present invention, since the hot air of the condenser side is blocked by the gap louver without being conducted to the radiator side, the cooling efficiency can be improved.
그리고, 응축기측 루버군을 통과한 공기가 갭루버의 안내를 받아 원활하게 라디에이터측으로 유동하여 공기의 압력손실이 적다.Then, the air passing through the condenser side louver group is smoothly flowed to the radiator side under the guidance of the gap louver, so that the pressure loss of the air is small.
