도 1 내지 도 3에 도시된 바와 같이, 본 발명은 차량의 루프(500)에 장착되는 케이스(100)와, 상기 케이스(100)에 회전가능하게 장착되는 열교환코어(200)와, 에어 흐름에 따라 상기 열교환코어(200)가 회전되도록 상기 열교환코어(200) 하부에 설치되어 송풍팬(300) 및, 입출되는 에어의 흐름을 가이드하도록 상기 케이스(100)의 상부에 고정 설치되는 가이드유닛(400)을 포함한다.As shown in FIGS. 1 to 3, the present invention provides a case 100 mounted to a roof 500 of a vehicle, a heat exchange core 200 rotatably mounted to the case 100, and an air flow. The guide unit 400 is installed in the lower portion of the heat exchange core 200 so that the heat exchange core 200 is rotated and fixedly installed at the upper portion of the case 100 to guide the flow of the blowing fan 300 and the air flowing in and out. ).

구체적으로 본 발명의 바람직한 일 실시예에 따른 케이스(100)는, 상기 열교환코어(200) 및 송풍팬(300)이 회전가능하게 위치되는 중공의 원통형 형상으로 형성되고, 해당 상부 가장자리에는 가이드유닛(400)이 설치된다.Specifically, the case 100 according to an embodiment of the present invention, the heat exchange core 200 and the blowing fan 300 is formed in a hollow cylindrical shape rotatably positioned, the upper edge of the guide unit ( 400) is installed.

상기 가이드유닛(400)은 상기 케이스(100)를 통해 차실내를 입출하는 에어의 흐름을 가이드하기 위한 것으로, 상기 케이스(100)의 상부 가장자리를 방사상으로 연결하여 고정하는 복수의 지지편(410)과, 차량의 진행방향에 대향되게 배치되는 격리판(420)으로 구성된다. The guide unit 400 is for guiding the flow of air entering and exiting the vehicle interior through the case 100, and a plurality of support pieces 410 for fixing by connecting the upper edge of the case 100 radially And a separator 420 disposed to face the traveling direction of the vehicle.

이때, 상기 격리판(420)은 외부에서 차실 내로 유입되는 외부 에어와 차실내에서 외부로 배출되는 실내 에어를 분리하는 역활을 한다.At this time, the separator 420 serves to separate the outside air introduced into the cabin from the outside and the indoor air discharged from the inside to the outside.

한편, 상기 열교환코어(200)는 중공의 원통형 회전가이드(210)와, 상기 회전가이드(210) 내측에 지그재그 형태로 배치되는 복수의 방열핀(220)으로 구성된다. 이러한 열교환코어(200)는 차실내에서 외부로 배출되는 에어와 외부에서 차실내로 유입되는 외부 에어 사이를 열교환하는데 사용한다. On the other hand, the heat exchange core 200 is composed of a hollow cylindrical rotation guide 210, a plurality of heat dissipation fins 220 arranged in a zigzag form inside the rotation guide 210. The heat exchange core 200 is used to heat exchange between the air discharged to the outside in the interior and the outside air introduced into the interior from the outside.

예컨대, 에어컨이 작동되는 여름철의 경우 상기 열교환코어(200)는 배출되는 실내의 저온 에어에 의해 냉각된 후 유입되는 외부 고온 에어를 냉각하고, 히터가 작동되는 겨울철의 경우 상기 열교환코어(200)는 배출되는 고온의 에어에 의해 가열된 후 유입되는 외부 저온 에어를 가열시킬 수 있다. For example, in the summer when the air conditioner is operated, the heat exchange core 200 cools the external high temperature air introduced after being cooled by the low temperature air in the room discharged, and in the winter when the heater is operated, the heat exchange core 200 is It is possible to heat the external low temperature air introduced after it is heated by the hot air discharged.

이때, 배출되는 실내 에어와 유입되는 외부 에어는, 상기 가이드유닛(400)의 격리판(420)을 기준으로 일측과 타측의 열교환코어(200)에서 각각 에어의 흐름이 이루어지는 바, 원활한 열교환을 위해 이들 실내 에어 및 외부 에어에 의해 열교환하는 열교환코어(200)는 회전되는 것이 바람직하다.At this time, the discharged indoor air and the introduced external air, the air flows in the heat exchange core 200 on one side and the other side based on the separator plate 420 of the guide unit 400, for smooth heat exchange It is preferable that the heat exchanging core 200 which exchanges heat by these indoor air and external air rotates.

이를 위해, 상기 열교환코어(200)의 하부에는, 에어 흐름에 의해 회전되는 송풍팬(300)이 설치된다. 상기 송풍팬(300)은 복수의 회전익(320)을 가지며, 해당 회전축(320)이 상기 가이드유닛(400)의 중심축(430)에 회전 가능하게 연결되고, 상기 열교환코어(200)에 고정됨에 따라, 에어 흐름에 따라 상기 열교환코어(200)가 회전되도록 할 수 있다. To this end, the lower portion of the heat exchange core 200, the blowing fan 300 is rotated by the air flow is installed. The blowing fan 300 has a plurality of rotor blades 320, the rotary shaft 320 is rotatably connected to the central axis 430 of the guide unit 400, and is fixed to the heat exchange core 200 Accordingly, the heat exchange core 200 may be rotated according to the air flow.

즉, 차실내에서 외부로 에어 흐름이 형성되는 경우 상기 송풍팬(300)이 일방 향으로 회전된다고 하면, 외부에서 차실내로 에어 흐름이 형성되는 경우 상기 송풍팬(300)은 타방향으로 회전될 수 있는 바, 이러한 송풍팬(300)은 양방향 송풍이 가능한 양방향 송풍팬일 수 있다. That is, if the blower fan 300 is rotated in one direction when the air flow is formed from the inside to the outside, the blower fan 300 is rotated in the other direction when the air flow is formed from the outside to the interior As can be seen, such a blowing fan 300 may be a two-way blowing fan capable of two-way blowing.

In this case, when the external hot air is introduced into the room through the heat exchange core 200, the external air may be cooled by a predetermined temperature by the cooled heat exchange core 200 and introduced into the room. This is possible because of the low temperature of the indoor air compared to the outside air by the operation of the air conditioner.

반면에, 히터가 작동되는 겨울철의 경우, 실내의 고온 에어는 상기 열교환코어(200)를 통해 외부로 배출되면서 상기 열교환코어(200)와 열교환되어 상기 열교환코어(200)를 가열시키는데, 이때, 외부의 저온 에어가 상기 열교환코어(200)를 통해 실내로 유입되면 외부 에어는 가열된 열교환코어(200)에 의해 소정 온도 가열되어 실내로 유입될 수 있다. 이는 히터의 작동에 의해 실내공기가 외부공기에 비하여 온도가 높기 때문에 가능하다.On the other hand, in the winter when the heater is operated, the high temperature air in the room is discharged to the outside through the heat exchange core 200 to be heat exchanged with the heat exchange core 200 to heat the heat exchange core 200, at this time, the outside When the low temperature air is introduced into the room through the heat exchange core 200, the external air may be heated to a predetermined temperature by the heated heat exchange core 200 and introduced into the room. This is possible because the temperature of the indoor air is higher than the external air by the operation of the heater.

이와 같이, 본 발명은 외부로 배출되는 실내 에어의 열에너지를 이용하여 실내로 유입되는 외부 에어와 열교환되도록 함으로써, 에어컨이 작동되는 여름철의 경우 냉방 손실을 줄이고 히터가 작동되는 겨울철의 경우 난방 손실을 줄일 수 있 다. 결국, 본 발명은 차량의 쾌적한 공기 조화를 실현하고, 차량 연비를 향상시킬 수 있는 것이다.As described above, the present invention uses the heat energy of the indoor air discharged to the outside to exchange heat with the external air introduced into the room, thereby reducing cooling loss in the summer when the air conditioner is operated and reducing heating loss in the winter when the heater is operated. Can be. As a result, the present invention can realize a comfortable air condition of the vehicle and improve the vehicle fuel economy.
