Description

경사지게 설치되는 튜브 구비 열교환기{Heat exchanger having tubes established to slant to the center}Heat exchanger having tubes established to slant to the center}

본 발명은 열교환기의 튜브를 열교환기의 중앙부를 향하여 경사지게 설치함으로써 열교환기 일측(좌측)을 통과하는 일측(좌측) 공기와 타측(우측)을 통과하는 타측(우측) 공기를 상호 혼합함으로써, 열교환기로부터 토출되는 공기가 균일한 온도를 나타낼 수 있도록 한 열교환기에 관한 것이다.According to the present invention, the tube of the heat exchanger is inclined toward the center of the heat exchanger, thereby mutually mixing one side (left) air passing through one side (left side) and the other side (right side) passing through the other side (right side). It relates to a heat exchanger such that the air discharged from the air can exhibit a uniform temperature.

도1은 열교환기 중에서 U-플로우 타입 열교환기의 개략적 단면도를 나타낸다.1 shows a schematic cross-sectional view of a U-flow type heat exchanger in a heat exchanger.

도1을 참조하면 종래의 U-플로우 타입 열교환기는 소정의 간격을 두고 상하로 나란하게 배열되는 상,하부 헤더탱크(1, 2)와, 상기 상,하부 헤더탱크(1, 2)가 상호 연통하도록 이들을 연결하는 다수의 튜브(3)와, 상기 튜브(3)들 사이에 각각 개재되는 다수의 방열핀(4)과, 상기 상,하부 헤더탱크(1, 2) 중 소정의 위치에 열교환 매체를 각각 유입하고 배출하도록 연결되는 입,출구 파이프(5, 6)와, 상기 튜브(3)들과 방열핀(4)들을 보강하기 위해 이들의 최외측에 설치된 사이드 서포트(7)로 구성되어 있다.Referring to FIG. 1, a conventional U-flow type heat exchanger communicates with upper and lower header tanks 1 and 2 arranged side by side at a predetermined interval, and the upper and lower header tanks 1 and 2 communicate with each other. A plurality of tubes 3 connecting them to each other, a plurality of heat dissipation fins 4 interposed between the tubes 3, and a heat exchange medium at predetermined positions among the upper and lower header tanks 1 and 2, respectively. It consists of inlet and outlet pipes 5 and 6 connected to the inlet and outlet, respectively, and side supports 7 installed at their outermost sides to reinforce the tubes 3 and the heat dissipation fins 4.

또한, 상기 상부 헤더탱크(2)의 내부에는 유입되는 열교환 매체와 배출되는 열교환 매체를 구획하는 배플(9)이 설치되어 열교환 매체가 상기 튜브(4)들을 구획단위로 통과하게 되는 것이다.In addition, a baffle 9 is disposed inside the upper header tank 2 so as to partition the incoming heat exchange medium and the discharge heat exchange medium so that the heat exchange medium passes through the tubes 4 in a partition unit.

상기와 같이 구성된 열교환기는 상기 입구파이프(5)를 통해 유입된 열교환 매체가 상기 상부 헤더탱크(1) 내부로 유입되어 충전된 후 상기 배플(9)에 의해 구획된 유입부(a)측의 튜브들을 통과하면서 상기 하부 헤더탱크(2) 내부로 흘러들어간 후 유턴하여 배출부(b)측의 튜브들을 통과하여 상부 헤더탱크(1)로 흘러간 후 상기 출구파이프(6)를 통해 배출되는 것이다.In the heat exchanger configured as described above, the heat exchange medium introduced through the inlet pipe 5 is introduced into the upper header tank 1 to be filled, and then the tube on the inlet part a side partitioned by the baffle 9. After passing through the lower header tank (2) flows into the U-turn through the tubes of the discharge portion (b) side flows to the upper header tank (1) and is discharged through the outlet pipe (6).

도2은 일반적인 원-웨이(One-Way) 방식 열교환기의 흐름을 도시한 것으로, 입구파이프(11)가 하부에 형성된 상기 제1 헤더탱크(10)의 좌측에, 출구파이프(12)가 상부에 형성된 상기 제2 헤더탱크(20) 좌측에 형성된 예를 도시하였다.FIG. 2 illustrates a flow of a typical one-way heat exchanger, in which an inlet pipe 11 is formed on the left side of the first header tank 10 and an outlet pipe 12 is formed on the upper side thereof. An example formed on the left side of the second header tank 20 is illustrated.

상기 도2에 도시한 원-웨이 방식 열교환기는 상기 입구파이프(11)를 통해 유입된 열교환매체가 제1 헤더탱크(20)의 길이방향으로 이동되면서 튜브(30)를 통해 상기 제2 헤더탱크(20)로 이동되고, 상기 제2 헤더탱크(20)의 길이방향으로 이동되어 상기 출구파이프(12)를 통해 배출된다.The one-way heat exchanger illustrated in FIG. 2 moves the heat exchange medium introduced through the inlet pipe 11 in the longitudinal direction of the first header tank 20 and passes through the tube 30 to the second header tank ( 20 is moved to the longitudinal direction of the second header tank 20 is discharged through the outlet pipe 12.

도2에 도시된 원-웨이(One-Way) 방식 열교환기는 도1에 도시된 종래의 U-플로우 타입 열교환기에서 냉각수측 압력강하량을 감소시키기 위하여 안출되었다. 즉, 엔진효율 향상 및 아이들 알피엠(idle rpm) 저하 등을 이유로 한 냉각수측 압력강하량을 감소시킬 필요에 의하여 안출되었다.The one-way heat exchanger shown in FIG. 2 is designed to reduce the amount of pressure drop on the coolant side in the conventional U-flow type heat exchanger shown in FIG. That is, it was devised by the need to reduce the coolant side pressure drop due to the improvement of the engine efficiency and the idle rpm decrease.

그러나, 도2에 도시된 원-웨이(One-Way) 방식 열교환기는 열교환매체의 흐름 방향 의 특성상 코아 표면온도(특히, 상하온도 편차)가 불균일하게 된다. 이러한 문제점에 대해서 개선이 필요하게 되었다.However, the one-way heat exchanger illustrated in FIG. 2 causes non-uniform core surface temperature (in particular, vertical temperature variation) due to the flow direction of the heat exchange medium. This problem needs to be improved.

It mixes at a certain vertical line O to make the temperature uniform. Therefore, compared to the case where the tube 300 is not inclined toward the center, there is an advantage that the air having a uniform temperature is discharged at a specific position on the rear side of the heat exchanger 1000.
