Description

적층형 열교환기{A HEAT EXCHANGER}Multilayer Heat Exchanger {A HEAT EXCHANGER}

본 발명은 적층형 열교환기에 관한 것으로, 더욱 상세하게는 플랫튜브의 하부측 후방 좌ㆍ우측 탱크부를 상호 연통시키는 연통로중에서 일부 연통로를 폐쇄함으로써, 과열영역의 발생을 방지하여 보다 효과적인 열교환 성능을 얻을 수 있도록 한 적층형 열교환기에 관한 것이다.The present invention relates to a laminated heat exchanger, and more particularly, by closing some of the communication paths in the communication path that communicates with the lower rear rear left and right tank portions of the flat tube, to prevent the occurrence of overheating zone to obtain more effective heat exchange performance It relates to a laminated heat exchanger.

일반적으로 적층형 열교환기는 도 1 내지 도 3에 도시된 바와 같이, 한쌍의 플레이트(1)(2)를 서로 면접합하여 상,하부에 각각 2열의 좌ㆍ우측 탱크부(3)(4)와, 상기 좌ㆍ우측 탱크부(3)(4) 사이에 연통 가능하게 형성되는 2열의 좌ㆍ우측 유체유동로를 갖도록 형성된 플랫튜브(5)들이 다수 적층되어, 유입된 열교환유체가 설정된 경로를 따라 좌ㆍ우측 탱크부(3)(4) 및 좌ㆍ우측 유체유동로를 지나 유동한 후 배출되도록 구성되어 있고, 상기 플랫튜브(5)의 최외측에 위치한 플랫튜브에 면접합되는 한쌍의 엔드 플레이트(6)(7)와, 상기 플랫튜브(5)의 플레이트(1)(2) 사이 및 엔드 플레이트(6)(7)와 플랫튜브(5) 사이에 개재되는 방열핀(8)으로 이루어져 있다.In general, as shown in FIGS. 1 to 3, a multilayer heat exchanger is a surface-bonded pair of plates (1) and (2), and two rows of left and right tanks (3) and (4), respectively, in the upper and lower portions. A plurality of flat tubes (5) formed to have two rows of left and right fluid flow paths formed to communicate between the left and right tank parts (3) and (4) are stacked, and the left and right heat exchange fluids flow along the set path. A pair of end plates (6) which are configured to flow after passing through the right tank (3) (4) and the left and right fluid flow paths, and are bonded to the flat tube located on the outermost side of the flat tube (5). ) And a heat dissipation fin (8) interposed between the plates (1) and (2) of the flat tube (5) and between the end plates (6) and the flat tube (5).

상기와 같이 구성된 적층형 열교환기(10)는 도 4에 도시된 바와 같은 열교환유체의 흐름을 가지도록 구성되어 있다.The stacked heat exchanger 10 configured as described above is configured to have a flow of heat exchange fluid as shown in FIG. 4.

즉, 열교환유체는 엔드 플레이트(6)(7)의 하부, 도면상에서 하부의 우측에형성된 유입구(11)를 통해 유입된 후, 플랫튜브(5)들의 하부에 형성된 우측 컵부(12)를 "A"방향으로 따라 유동된 다음, 열교환기(10)의 대략 중간(C;Center)에서 유동이 정지된다.That is, the heat exchange fluid flows through the inlet 11 formed at the bottom of the end plates 6 and 7 and in the bottom right of the drawing, and then the right cup 12 formed at the bottom of the flat tubes 5 is “A”. Flow along the " direction, then the flow stops at approximately C (Center) center of the heat exchanger (10).

여기서, 상기 유체가 하류 우측컵부(12) 전방 절반영역(S1)까지 유동된 후,또 다른 하류 우측컵부(12) 후방 절반영역(S2)까지 유동하지 못하는 이유는 열교환기의 대략 중간(C)를 기점으로 하여 우측 컵부(12)들이 도 3에 도시된 바와 같이, 연통되어 있지 않기 때문이다.The reason why the fluid does not flow to the downstream half-side region S2 after the downstream right cup portion 12 and the downstream half-side region S1 after the downstream right cup portion 12 is about the middle C of the heat exchanger. This is because the right cup portions 12 do not communicate with each other, as shown in FIG. 3.

즉, 하류 우측컵부(12) 전방 절반영역(S1)까지 유동된 열교환유체는 플랫튜브(5)의 우측 전방 유체유동로(13)를 따라 상승하여 상류 우측컵부(14) 전후방영역(S3)까지 유동된 후, 플랫튜브(5)의 우측 후방 유체유동로(15)를 따라 하강한다.That is, the heat exchange fluid flowing to the downstream right side cup part 12 front half area S1 rises along the right front fluid flow path 13 of the flat tube 5 to the front and rear areas S3 upstream right cup part 14. After flowing, it descends along the right rear fluid flow path 15 of the flat tube 5.

다음으로, 우측 후방 유체유동로(15)를 따라 하강된 유체는 하류 우측컵부 (12)후방 절반영역(S2)으로 유동된 다음, 하류 좌측컵부(16) 후방 절반영역(S5)으로 유동된 후, 다시 좌측 후방 유체유동로(17)를 따라 상승하여 상류 좌측컵부(18) 전후방영역(S6)까지 유동된다.Next, the fluid lowered along the right rear fluid flow path 15 flows into the downstream half region S2 downstream of the downstream right cup portion 12, and then flows into the rear half region S5 downstream of the downstream left cup portion 16. Then, it rises again along the left rear fluid flow path 17 and flows up and down the front left region 18 of the upstream cup portion 18.

여기서, 상기 우측컵부(12)의 후방 절반영역(S2)에 있는 유체는 도 3에 도시된 바와 같이, 연통로(21)를 통해 하루 좌측컵부(16)의 후방 절반영역(S5)으로 유동된다.Here, the fluid in the rear half region S2 of the right cup portion 12 flows to the rear half region S5 of the left cup portion 16 through the communication path 21 as shown in FIG. 3. .

이렇게, 상류 좌측컵부(18) 전후방영역(S6)까지 유동된 유체는 좌측 전방 유체유동로(19)를 따라 하강하여 하류 좌측컵부(18) 전방 절반영역(S7)로 유동된 후,엔드 플레이트(6)(7) 하부에 형성된 배출구(20)를 통해 최종적으로 배출된다.Thus, the fluid flowing to the upstream left cup portion 18 front and rear region S6 descends along the left front fluid flow path 19 and flows to the downstream left cup portion 18 front half region S7, and then the end plate ( 6) (7) is finally discharged through the outlet 20 formed in the lower portion.

상기와 같이 구성된 종래 기술에 따르면, 유체가 하류 우측컵부(12) 후방영역(S1)에서 하류 좌측컵부(16) 후방영역(S5)으로 유동하는 경로를 갖는데, 이 경로에서는 하류 우측컵부(12) 후방영역(S2)에서 모든 유체가 하류 좌측컵부(16) 후방영역(S5)으로 유동하기 때문에, 도 5에 도시된 바와 같이, 적외선 카메라로 찍은 결과 D영역이 E영역보다 온도가 상승하는 등 온도 편차가 심하게 발생되는 과열영역이 존재하였다.According to the prior art configured as described above, the fluid has a path from the downstream right cup portion 12 rear region S1 to the downstream left cup portion 16 rear region S5, in which the downstream right cup portion 12 In the rear region S2, all the fluid flows to the downstream left cup portion 16 rear region S5. As shown in FIG. 5, the temperature of the region D is higher than the region E as shown in FIG. There was an overheated zone where the deviation was severe.

이 과열영역이 존재함으로 인해 보다 효과적인 열교환 성능을 얻을 수 없는 문제점이 있었다.Due to the presence of this superheated area, there was a problem that a more effective heat exchange performance could not be obtained.

본 발명은 상기와 같은 문제점을 해결하기 위해 창안된 것으로, 플랫튜브의 하부측 후방 좌ㆍ우측 탱크부를 상호 연통시키는 연통로중에서 일부 연통로를 폐쇄함으로써, 과열영역의 발생을 방지하여 보다 효과적인 열교환 성능을 얻을 수 있도록 한 적층형 열교환기를 제공하는 것을 목적으로 한다.The present invention was devised to solve the above problems, and by closing some of the communication paths in the communication path that communicates with the lower left rear left and right tanks of the flat tube, prevents the occurrence of overheating zone more effective heat exchange performance An object of the present invention is to provide a laminated heat exchanger.

In a multi-layered heat exchanger configured to stack a plurality of flat tubes formed to have a left and right fluid flow path, and flows through the left and right tank part and the left and right fluid flow path along a set path, and discharges the introduced heat exchange fluid. And a part of the communication paths closed in the communication paths communicating with the lower rear rear left and right tank parts of the flat tube.

이하, 본 발명에 의한 열교환기의 바람직한 실시예를 첨부된 도면을 참조하여 상세하게 설명하면 다음과 같다.Hereinafter, preferred embodiments of the heat exchanger according to the present invention will be described in detail with reference to the accompanying drawings.

본 발명은, 한쌍의 플레이트(1)(2)를 서로 면접합하여 상,하부에 각각 2열의 좌ㆍ우측 탱크부(3)(4)와, 상기 좌ㆍ우측 탱크부(3)(4) 사이에 연통 가능하게 형성되는 2열의 좌ㆍ우측 유체유동로를 갖도록 형성된 플랫튜브(5)들이 다수 적층되어, 유입된 열교환유체가 설정된 경로를 따라 좌ㆍ우측 탱크부(3)(4) 및 좌ㆍ우측 유체유동로를 지나 유동한 후 배출되도록 구성되어 있고, 상기 플랫튜브(5)의 최외측에 위치한 플랫튜브(5)에 면접합되는 한쌍의 엔드 플레이트(6)(7)와, 상기 플랫튜브(5)의 플레이트(1)(2) 사이 및 엔드 플레이트(6)(7)와 플랫튜브(5) 사이에 개재되는 방열핀(8)으로 이루어지는 것으로, 이는 종래와 동일하며, 이에 대한 도면은 도 1을 참고하기로 한다.According to the present invention, a pair of plates (1) and (2) are bonded to each other, and the upper and lower tanks each have two rows of left and right tanks 3 and 4 between the left and right tanks 3 and 4, respectively. A plurality of flat tubes (5) formed to have two rows of left and right fluid flow paths formed in communication with each other are stacked so that left and right tanks (3) (4) and left A pair of end plates 6 and 7 which are configured to be discharged after flowing through the right fluid flow path, and are bonded to the flat tube 5 located at the outermost side of the flat tube 5, and the flat tube. It consists of a heat dissipation fin (8) interposed between the plates (1) (2) of (5) and between the end plates (6) (7) and the flat tube (5), which is the same as in the prior art, and the figure is shown in FIG. See 1.

상기와 같이 구성된 적층형 열교환기는 도 8에 도시된 바와 같은 열교환유체의 흐름을 가지도록 구성되어 있다.The laminated heat exchanger configured as described above is configured to have a heat exchange fluid flow as shown in FIG. 8.

즉, 열교환유체는 엔드 플레이트(6)(7)의 하부, 도면상에서 하부의 우측에형성된 유입구(11)를 통해 유입된 후, 플랫튜브(5)들의 하부에 형성된 우측컵부(12)를 "A"방향으로 따라 유동된 다음, 열교환기의 대략 중간(C;Center)에서 유동이 정지된다.That is, the heat exchange fluid flows through the inlet 11 formed at the bottom of the end plates 6 and 7 and in the bottom right of the drawing, and then the right cup part 12 formed at the bottom of the flat tubes 5 is “A”. Flow along the " direction, then the flow stops at approximately C (Center) of the heat exchanger.

여기서, 상기 유체가 하류 우측컵부(12) 전방 절반영역(S1)까지 유동된 후, 또 다른 하류 우측컵부(12) 후방 절반영역(S2)까지 유동하지 못하는 이유는 열교환기의 대략 중간(C)를 기점으로 하여 우측컵부(12)들이 도 6에 도시된 바와 같이, 연통되어 있지 않기 때문이다.The reason why the fluid does not flow to the downstream half-side region S2 after the downstream right cup portion 12 after flowing to another downstream right-side cup portion 12 is about the middle C of the heat exchanger. This is because the right side cup portions 12 do not communicate with each other as shown in FIG. 6.

즉, 하류 우측컵부(12) 전방 절반영역(S1)까지 유동된 열교환유체는 플랫튜브(5)의 우측 전방 유체유동로(13)를 따라 상승하여 상류 우측컵부(14) 전후방영역(S3)까지 유동된 후, 플랫튜브(5)의 우측 후방 유체유동로(15)를 따라 하강한다.That is, the heat exchange fluid flowing to the downstream right side cup part 12 front half area S1 rises along the right front fluid flow path 13 of the flat tube 5 to the front and rear areas S3 upstream right cup part 14. After flowing, it descends along the right rear fluid flow path 15 of the flat tube 5.

다음으로, 우측 후방 유체유동로(15)를 따라 하강된 유체는 하류 우측컵부(12) 후방 절반영역(S2)으로 유동된 다음, 하류 좌측컵부(16) 후방 절반영역(S5)으로 유동된 후, 다시 좌측 후방 유체유동로(17)를 따라 상승하여 상류 좌측컵부(18) 전후방영역(S6)까지 유동된다.Next, the fluid lowered along the right rear fluid flow path 15 flows into the downstream right side cup region 12 rear half region S2 and then flows into the downstream left side cup region 16 rear half region S5. Then, it rises again along the left rear fluid flow path 17 and flows up and down the front left region 18 of the upstream cup portion 18.

한편, 본 발명은 상기 플랫튜브(5)의 하부측 후방 좌ㆍ우측 탱크부(3)(4)를 상호 연통시키는 연통로(30)중에서 일부 연통로를 폐쇄하는 것으로, 도 6에 도시된 바와 같이, 좀더 상세하게는 상기 연통로(30)는 상기 하부측 후방 좌ㆍ우측 탱크부(3,4)에서 절반과 열교환기의 외측 사이의 영역에 형성되고, 상기 하부측 후방 좌ㆍ우측 탱크부(3,4)에서 절반과 열교환기의 중심 사이의 영역이 폐쇄되게 형성된다.On the other hand, the present invention is to close a part of the communication path in the communication path 30 for communicating the lower side rear left and right tank portion (3) (4) of the flat tube (5), as shown in FIG. Similarly, more specifically, the communication path 30 is formed in an area between the half of the lower rear left and right tanks 3 and 4 and the outside of the heat exchanger, and the lower rear left and right tank parts. In (3,4) the area between the half and the center of the heat exchanger is formed closed.

그리고, 다른 실시예로 도 7에 도시된 바와 같이, 상기 연통로(30)는 상기 하부측 후방 좌ㆍ우측 탱크부(3,4)에서 절반과 열교환기의 중심 사이의 영역에 형성되고, 상기 하부측 후방 좌ㆍ우측 탱크부(3,4)에서 절반과 열교환기의 외측 사이의 영역이 폐쇄되게 할 수 도 있다.In another embodiment, as shown in FIG. 7, the communication path 30 is formed in an area between the half of the lower rear left and right tanks 3 and 4 and the center of the heat exchanger. In the lower rear rear left and right tank parts 3 and 4, the area between the half and the outside of the heat exchanger may be closed.

따라서, 상기 우측컵부(12)의 후방 절반영역(S2)에 있는 유체는 연통로(30) 전체를 통해 하루 좌측컵부(16)의 후방 절반영역(S5)으로 유동되지 못하고 H선을 기준으로 하여 일부 개구된 연통로를 통해 유동된다.Therefore, the fluid in the rear half region S2 of the right cup portion 12 does not flow to the rear half region S5 of the left cup portion 16 a day through the entire communication path 30 and is based on the H line. It flows through some open communication paths.

따라서, 상기와 같이 연통로(30)를 제한적으로 폐쇄한 결과, 도 9에 도시된 바와 같이, 적외선 카메라로 찍은 결과 G영역과 F영역의 온도가 거의 동일하게 나타나는 등 온도 편차가 거의 발생되지 않았다.Therefore, as a result of the closed closing of the communication path 30 as described above, as shown in FIG. 9, the temperature was hardly generated such that the temperature of the G region and the F region was almost the same as the result of the infrared camera. .

즉, 종래에서처럼 과열영역이 존재하지 않음에 따라 보다 효과적인 열교환 성능을 얻을 수 있었다.That is, as there is no superheated region as in the prior art, more effective heat exchange performance could be obtained.

그리고, 상기와 같이 연통로(30)를 제한적으로 폐쇄한 결과, 냉매 편중되어 유동하지 않고 골고루 유동하여 열교환 성능의 향상을 기대할 수 있다.As a result of the closed closing of the communication path 30 as described above, it is possible to expect the improvement of the heat exchange performance by flowing evenly without the refrigerant being decentralized and flowing.

이상 살펴본 바와 같이, 본 발명에 의한 적층형 열교환기에 따르면, 플랫튜브의 하부측 후방 좌ㆍ우측 탱크부를 상호 연통시키는 연통로중에서 일부 연통로를 함으로써, 과열영역의 발생을 방지하여 보다 효과적인 열교환 성능을 얻을 수 있다.As described above, according to the laminated heat exchanger according to the present invention, by performing a part of communication paths in the communication paths communicating with the lower rear rear left and right tank portions of the flat tube, it is possible to prevent the occurrence of overheating zone and obtain more effective heat exchange performance. Can be.
