근래 자동차 산업에 있어서 세계적으로 환경과 에너지에 대한 관심이 높아짐에 따라 연비 개선을 위한 연구가 이루어지고 있으며 다양한 소비자의 욕구를 만족시키기 위해 경량화, 소형화 및 고기능화를 위한 연구개발이 꾸준히 이루어지고 있다.Recently, as interest in the environment and energy has increased globally in the automobile industry, research has been conducted to improve fuel efficiency, and research and development for weight reduction, miniaturization, and high functionality are continuously conducted to satisfy the needs of various consumers.

특히 차량용 공조시스템에 있어서, 대개 엔진룸 내부에서 충분한 공간을 확보하기 어려운 실정이기 때문에 상기 차량용 공조시스템을 구성하는 열교환기 등의 구성은 소형이면서도 효율을 높일 수 있는 기능이 요구되고 있다.In particular, in vehicle air conditioning systems, it is generally difficult to secure sufficient space inside the engine room, so the heat exchanger that constitutes the vehicle air conditioning system is required to be compact and have the function of increasing efficiency.

종래의 열교환기는 일례로, 도 1과 같이 열교환기는 복수의 플레이트가 적층되어 형성되고, 복수의 플레이트의 적층에 의해 열교환매체가 유동되는 유로가 형성된 코어부(10), 코어부(10)의 일면에 형성되어 열교환매체가 유입되는 입구부(20) 및 코어부(10)의 일면에 형성되어 열교환매체가 배출되는 출구부(30)를 포함할 수 있다. 그리고 입구부(20)에서 출구부(30) 쪽으로 코어부(10) 내부를 통해 열교환매체가 유동되는 유동 경로는 단일 패스(single pass)로 형성된다. 즉, 단일 패스로 구성된 열교환기에서는 열교환매체의 입구부(20)와 출구부(30)가 동일한 방향쪽의 면에 배치될 수 있다.As an example of a conventional heat exchanger, as shown in FIG. 1, the heat exchanger is formed by stacking a plurality of plates, and includes a core portion 10 in which a flow path through which the heat exchange medium flows is formed by the stacking of the plurality of plates, and one surface of the core portion 10. It may include an inlet portion 20 formed in the inlet through which the heat exchange medium flows, and an outlet portion 30 formed on one side of the core portion 10 through which the heat exchange medium is discharged. And the flow path through which the heat exchange medium flows through the inside of the core part 10 from the inlet part 20 to the outlet part 30 is formed as a single pass. That is, in a heat exchanger configured as a single pass, the inlet portion 20 and the outlet portion 30 of the heat exchange medium may be disposed on surfaces in the same direction.

하지만 도 2와 같이 열교환 성능을 향상시키기 위해 코어부(10)의 내부에 배플 플레이트(40)를 배치하여 열교환매체의 유동 경로가 멀티 패스(multi-pass)로 형성된 열교환기에서는, 열교환매체의 입구부(20)와 출구부(30)가 서로 다른 방향쪽의 면에 배치된다. 따라서 모듈화를 위해 열교환매체의 입구부 및 출구부에 매니폴드 등을 적용해 연결되도록 하거나, 기술의 고도화를 위해 입구부 및 출구부에 밸브나 센서 등을 집적화하는 경우, 열교환기의 일측에 입구부 및 출구부를 함께 배치시켜야 하는데 이를 위해서는 추가적인 우회 유로를 형성해야만 하는 단점이 있다.However, in a heat exchanger in which the flow path of the heat exchange medium is formed as a multi-pass by arranging the baffle plate 40 inside the core portion 10 to improve heat exchange performance as shown in FIG. 2, the inlet of the heat exchange medium The portion 20 and the outlet portion 30 are disposed on surfaces in different directions. Therefore, when manifolds, etc. are connected to the inlet and outlet parts of the heat exchange medium for modularization, or when valves or sensors are integrated into the inlet and outlet parts to advance technology, the inlet part is installed on one side of the heat exchanger. and outlet parts must be placed together, but this has the disadvantage of having to form an additional bypass passage.

Here, the heat exchange medium flowing into the core portion 100 may flow through the internal pipe 400 and flow into the area of the inlet portion 104 adjacent to the first pass P1, which is the first pass. Afterwards, it passes through the discharge section 105 through the first pass (P1), then passes between the inlet section 105 and the internal pipe 400 through the second pass (P2), and then through the third pass (P3). It can be discharged to the outside of the core part 100 through the discharge part 105.
