본 발명은 차량의 에어건조기에 관한 것으로, 특히 에어압축기로부터 에어건조기로 유입되는 에어의 온도를 적절히 조절해서 에어건조기의 성능을 향상시키도록 한 에어건조기의 에어유입온도 조절장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air dryer of a vehicle, and more particularly, to an air inlet temperature control apparatus of an air dryer configured to improve the performance of an air dryer by appropriately adjusting the temperature of air introduced from the air compressor to the air dryer.

종래 차량의 에어건조기는 에어압축기에서 토출되는 에어를 건조시켜 에어탱크로 공급하게 되어 있는 데, 도 1에는 상기와 같은 에어건조기의 에어 유출입 관 계를 나타내는 구성이 도시되어 있다.Conventionally, an air dryer of a vehicle is configured to dry air discharged from an air compressor and supply the air to an air tank.

즉, 외기를 흡입하여 에어를 압축시키는 에어압축기(1)에는 에어크리너에 의해 정화된 에어를 흡입하는 흡입포트(1a)와, 흡입된 에어를 압축시켜 토출하는 토출포트(1b)가 각각 구비되어 있고, 상기 토출포트에서 토출된 에어는 에어건조기(2)로 유입되어 수분 등이 제거된 다음에 에어탱크(3)로 보내어져서 저장되게 되어 있다.That is, the air compressor 1 for sucking air and compressing air is provided with a suction port 1a for sucking air purified by an air cleaner and a discharge port 1b for compressing and discharging the sucked air. The air discharged from the discharge port flows into the air dryer 2 to remove moisture and the like, and is then sent to the air tank 3 to be stored.

그런데, 차종에 따라서는 에어압축기와 에어건조기 사이의 거리가 다르므로 에어건조기로 유입되는 에어의 온도에 차이가 있고, 차량의 고속 주행이나 시내 주행과 같이 주행 모드에 따라서 에어압축기로부터 토출되는 에어의 온도가 상이해서 에어건조기로 유입되는 에어의 온도에 차이가 있게 된다.However, since the distance between the air compressor and the air dryer differs according to the vehicle type, there is a difference in the temperature of the air flowing into the air dryer, and the air discharged from the air compressor according to the driving mode such as the high speed driving or the city driving of the vehicle Since the temperature is different, there is a difference in the temperature of the air flowing into the air dryer.

그런데, 에어건조기가 최적의 성능을 발휘하려면 적절한 온도로 에어가 유입되어야 하는 데, 이를 위해 종래에는 에어압축기와 에어건조기 사이의 연결파이프의 거리를 조절하는 방안 등이 제안되어 있지만 에어건조기로 유입되는 에어의 온도를 최적으로 조절하는 데에는 미흡하다고 하는 결점이 있었다.By the way, in order to achieve the best performance of the air dryer, air must be introduced at an appropriate temperature. For this purpose, a method of controlling the distance of the connection pipe between the air compressor and the air dryer has been proposed. There was a drawback to being inadequate in controlling the temperature of air.

이에 본 발명은 상기와 같은 사정을 감안하여 안출된 것으로, 에어압축기로부터 토출되는 에어의 온도를 2단계로 구분해서 에어 온도의 높고 낮음에 따라 에어건조기로 유입되는 에어의 온도를 적절히 조절하여 에어건조기의 성능을 향상시키도록 한 에어건조기의 에어유입온도 조절장치를 제공함에 그 목적이 있다.Accordingly, the present invention has been made in view of the above circumstances, and by dividing the temperature of the air discharged from the air compressor into two stages, according to the high and low air temperature, the temperature of the air flowing into the air dryer is properly adjusted. It is an object of the present invention to provide an air inlet temperature control device for an air dryer to improve the performance of the air dryer.

상기와 같은 목적을 달성하기 위한 본 발명은, 압축된 고온의 공기가 직접 토출되게 하는 제1토출포트와 냉각수단을 통해 냉각되게 하여 상대적으로 낮은 온도의 에어가 토출되게 하는 제2토출포트를 구비한 에어압축기와, 에어건조기로 유입되는 에어의 온도를 감지해서 감지한 온도에 따라 상기 2개의 토출포트를 통해 토출되는 온도가 상이한 2종류의 에어를 선택적으로 상기 에어건조기로 유입되게 하는 제어수단을 갖추고 있다.The present invention for achieving the above object is provided with a first discharge port for direct discharge of compressed high-temperature air and a second discharge port for cooling the air of a relatively low temperature by cooling through the cooling means; One air compressor and a control means for sensing the temperature of the air flowing into the air dryer and selectively introducing two kinds of air having different temperatures discharged through the two discharge ports according to the sensed temperature. Equipped.

바람직하기로는, 상기 냉각수단이 상기 에어압축기에 형성시킨 냉각로를 따라 유동하는 냉각수를 갖춘 것을 특징으로 한다.Preferably, the cooling means has a cooling water flowing along the cooling path formed in the air compressor.

또한, 상기 제어수단이 상기 에어건조기에 유입되는 에어의 온도를 감지하는 온도센서와, 상기 에어압축기와 에어건조기 사이의 연결통로에 설치되어 상기 에어압축기로부터 유입되는 2종류의 에어 중에 어느 한 종류의 에어만 유출되게 하는 버터플라이밸브, 상기 온도감지센서를 매개로 에어건조기로 유입되는 온도를 감지해서 감지한 온도에 따라 상기 버터플라이밸브를 제어하는 엔진제어유니트를 구비한 것을 특징으로 한다.In addition, the control means is a temperature sensor for sensing the temperature of the air flowing into the air dryer, and any one of the two types of air introduced from the air compressor installed in the connecting passage between the air compressor and the air dryer A butterfly valve for allowing only air to flow out, and an engine control unit for controlling the butterfly valve according to the sensed temperature by sensing the temperature flowing into the air dryer through the temperature sensor.

그리고, 상기 버터플라이밸브가 회전축을 매개로 회전해서 유입된 2종류의 에어 중에 어느 한 종류의 에어만 유출되게 하는 밸브판과, 상기 엔진제어유니트로부터 제어신호를 인가받아 상기 밸브판을 회전시키기 위해 상기 회전축에 연결된 모터를 구비한 것을 특징으로 한다.And a valve plate for allowing only one type of air to flow out of the two types of air introduced by rotating the butterfly valve through a rotating shaft, and for receiving the control signal from the engine control unit to rotate the valve plate. And a motor connected to the rotating shaft.

이하 본 발명의 실시예를 첨부된 예시도면을 참조로 상세히 설명한다.Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings.

도 2에는 본 발명에 따른 에어건조기의 에어유입온도 조절장치의 구성이 도 시되어 있는 바, 에어크리너와 연결되어 에어크리너에서 정화된 공기를 흡입하여 압축시켜 토출하는 에어압축기(11)에는 상기 에어크리너와 연결된 흡입포트(11a)가 형성되어 있고, 상기 에어압축기에서 압축된 에어를 토출하는 2개의 서로 분리된 토출포트(11b,11c)가 구비되어 있다.Figure 2 shows the configuration of the air inlet temperature regulating device of the air dryer according to the present invention, the air compressor 11 is connected to the air cleaner to suck and discharge the purified air in the air cleaner 11 to discharge the air A suction port 11a connected to the cleaner is formed, and two separate discharge ports 11b and 11c for discharging the compressed air from the air compressor are provided.

상기 제1토출포트(11b)는 에어압축기에서 압축된 에어를 직접 토출하는 포트인 반면에, 제2토출포트(11b)는 에어압축기의 상부에 형성된 헤드부(11d)의 내부에 구비되어 있는 적절한 냉각수단으로 에어를 냉각시켜 에어를 토출하는 포트이다.The first discharge port 11b is a port for directly discharging the compressed air from the air compressor, while the second discharge port 11b is appropriately provided inside the head portion 11d formed on the upper portion of the air compressor. A port for cooling the air by the cooling means to discharge the air.

즉, 상기 헤드부(11d)의 내부에는 도 3에 도시된 바와 같이 냉각수가 유동하는 냉각로(11e)가 형성되어 있어서 에어압축기에서 압축된 고온의 에어가 상기 냉각로를 따라서 유동하여 냉각로의 냉각수와 열교환을 통해 냉각되게 된다.That is, a cooling path 11e through which cooling water flows is formed inside the head portion 11d, so that the hot air compressed by the air compressor flows along the cooling path to provide a cooling path. It is cooled by heat exchange with cooling water.

그리고, 상기 에어압축기에서 토출되는 에어는 에어건조기(12)로 유입된 다음에 수분 등이 제거된 후에 에어탱크(13)로 보내어져서 저장되게 된다.Then, the air discharged from the air compressor is introduced into the air dryer 12, and then the water is removed and sent to the air tank 13 to be stored.

상기 에어압축기와 에어건조기 사이의 연결통로에는 상기 에어압축기로부터 토출된 고온 및 저온의 압축공기를 선택적으로 상기 에어건조기로 유입되게 하는 공지의 버터플라이밸브(14)가 설치되어 있다.In the connection passage between the air compressor and the air dryer, a well-known butterfly valve 14 is installed to selectively allow the hot and cold compressed air discharged from the air compressor to selectively flow into the air dryer.

상기 버터플라이밸브(14)는 2종류의 에어가 유입되면 회전축(14a)을 매개로 회전하면서 내부의 통로를 개폐하는 밸브판(14b)을 갖추고서 어느 한 종류의 에어만 유출되게 하는 기능을 가지고 있다.The butterfly valve 14 has a function of allowing only one type of air to flow out by having a valve plate 14b for opening and closing an internal passage while rotating through a rotating shaft 14a when two types of air are introduced therein. have.

상기 회전축(14a)을 제어해서 상기 밸브판을 조절하기 위해 상기 회전축에는 예컨대 모터가 설치되고, 상기 모터는 엔진제어유니트(ECU)의 출력단에 접속되어, 상기 엔진제어유니트의 제어신호에 따라 상기 모터가 구동되어 상기 밸브판을 조작하게 된다.A motor is installed in the rotary shaft to control the rotary shaft 14a to adjust the valve plate, for example, the motor is connected to an output terminal of an engine control unit (ECU), and the motor according to the control signal of the engine control unit. Is driven to manipulate the valve plate.

또한, 상기 연결통로에는 에어건조기로 유입되는 공기의 온도를 감지하는 온도센서(15)가 설치되고, 상기 온도센서에서 감지된 온도신호를 상기 엔진제어유니트로 입력되게 온도센서가 엔진제어유니트의 입력단에 접속되어 있다.In addition, the connection passage is provided with a temperature sensor 15 for detecting the temperature of the air flowing into the air dryer, the temperature sensor is input to the engine control unit so that the temperature signal detected by the temperature sensor to the engine control unit Is connected to.

이에 따라, 상기 엔진제어유니트는 상기 에어건조기로 유입되는 에어의 온도를 상기 온도센서를 매개로 감자한 다음에 에어의 온도가 높고 낮음에 따라 상기 버터플라이밸브를 제어하게 되는 데, 즉 에어건조기로 유입되는 에어의 온도가 높은 것으로 판단되면 상기 엔진제어유니트가 상기 모터에 제어신호를 인가해서 버터플라이밸브의 밸브판을 조작하여 상기 제2토출포트로부터 토출되는 상대적으로 온도가 낮은 에어가 에어건조기로 유입되게 한다.Accordingly, the engine control unit controls the butterfly valve as the temperature of the air is high and low after deciding the temperature of the air flowing into the air dryer through the temperature sensor, that is, the air dryer. When it is determined that the temperature of the inlet air is high, the engine control unit applies a control signal to the motor to operate the valve plate of the butterfly valve to discharge the relatively low temperature air discharged from the second discharge port to an air dryer. Allow inflow

한편, 상기 엔진제어유니트가 온도센서를 매개로 감지한 에어의 온도가 낮은 것으로 판단되면 상기 모터에 제어신호를 인가하여 상기 에어압축기의 제1토출포트로부터 토출되는 에어가 상기 에어건조기로 유입되도록 상기 버터플라이밸브의 밸브판을 제어하게 된다.On the other hand, if it is determined that the temperature of the air detected by the engine control unit via a temperature sensor is low, the control signal is applied to the motor so that the air discharged from the first discharge port of the air compressor flows into the air dryer. The valve plate of the butterfly valve is controlled.

이와 같이 엔진제어유니트가 에어건조기로 유입되는 에어의 온도를 감지해서 적절한 온도를 가진 에어가 유입되게 함으로써, 에어건조기의 성능을 향상시킬 수 있게 되는 것이다.In this way, the engine control unit senses the temperature of the air flowing into the air dryer to allow the air having an appropriate temperature to flow therein, thereby improving the performance of the air dryer.

이상 설명한 바와 같이 본 발명에 따른 에어건조기의 에어유입온도 조절장치 에 의하면, 에어압축기로부터 토출되는 서로 상이한 온도를 가진 2종류의 에어 중에 최적의 온도를 가진 에어가 에어건조기로 유입되게 제어함으로써, 에어건조기가 항상 최적의 성능을 발휘하도록 하여 차량의 출력 성능을 높일 수 있는 등의 효과가 있게 된다.As described above, according to the air inlet temperature control apparatus of the air dryer according to the present invention, the air having the optimum temperature is introduced into the air dryer among the two types of air having different temperatures discharged from the air compressor, It is possible to increase the output performance of the vehicle by ensuring that the dryer always performs optimally.
