Description

철도차량용 에어컨덕트 소음기{Silencer of duct for air conditioner of train}Air conditioner duct silencer for railway vehicle {Silencer of duct for air conditioner of train}

본 발명은 에어컨으로부터 발생하는 소음이 철도차량의 실내로 유입되는 것을 방지하기 위한 에어컨덕트 소음기에 대한 것으로서, 더욱 상세하게는 에어컨의 송풍기에서 공기가 나가는 아웃렛 뿐만 아니라 쿨러로 공기가 유입되는 인렛으로도 소음이 방출되는 것을 방지할 수 있는 철도차량용 에어컨덕트 소음기에 대한 것이다.The present invention relates to an air conditioner duct silencer for preventing noise from the air conditioner from flowing into the interior of a railway vehicle. More specifically, the air inlet is introduced into the cooler as well as an inlet into which the air flows from the blower of the air conditioner. The present invention relates to an air conditioner duct silencer for railway vehicles that can prevent noise from being emitted.

등록특허 제10-0533112호에는 종래의 철도차량용 에어컨덕트 소음기에 대하여 개시되어 있다. 도 5는 등록특허 제10-0533112호에 개시된 철도차량용 에어컨덕트 소음기의 개념도이다.Patent No. 10-0533112 discloses a conventional air conditioner duct silencer for railway vehicles. 5 is a conceptual diagram of an air conditioner duct silencer for a railway vehicle disclosed in Korean Patent No. 10-0533112.

도 5에 개시된 소음기는 중간안내깃(15)과, 하부안내깃(14)과, 제1스플리터(19)를 포함한다. 여기서 중간안내깃(15)과 하부안내깃(14)과 제1스플리터(19)는 송풍기(1)에서 공기가 유출되는 아웃렛(5)에 설치된다. 아웃렛(5)에 설치되어 아웃렛(5)을 통하여 유출되는 송풍기(1)의 소음이 철도차량의 실내로 유입되는 것을 방지한다. 이를 위하여 중간안내깃(15)과 하부안내깃(14)은 덕트의 수평부와 수직부가 교차되는 지점에 배치된다.The silencer disclosed in FIG. 5 includes an intermediate guide vane 15, a lower guide vane 14, and a first splitter 19. Here, the intermediate guide feather 15, the lower guide feather 14, and the first splitter 19 are installed in the outlet 5 through which air flows from the blower 1. It is installed in the outlet (5) to prevent the noise of the blower (1) flowing through the outlet (5) to enter the interior of the railway vehicle. To this end, the intermediate guide vanes 15 and the lower guide vanes 14 are disposed at points where the horizontal and vertical sections of the duct intersect.

그리고 중간안내깃(15)은 수직과 수평의 덕트(13)가 교차하는 통로의 가운데 부분에 일정한 크기와 규칙적인 간격을 가진 구멍이 형성된 타공판을 유입공기의 흐름에 맞추어 라운딩되게 구성된다.And the intermediate guide feather 15 is configured to round the perforated plate formed in the center portion of the passage where the vertical and horizontal ducts 13 intersect with the flow of the inlet air.

수직과 수평의 덕트(13)가 교차하는 모서리에는 유입공기의 흐름에 맞추어 라운딩된 타공판을 표면부재로 하고 그 내부에는 흡음재(18)를 충진한 하부 안내깃(14)을 배치하여 송풍기(1)로부터 유입되는 소음을 1차적으로 저감한다.At the corner where the vertical and horizontal ducts 13 intersect, the perforated plate rounded according to the flow of inlet air is used as the surface member, and the lower guide feather 14 filled with the sound absorbing material 18 is disposed therein, and the blower 1 First, reduce the noise coming from.

스플리터(19)는 분배기의 상부에 구비되어 덕트(13) 내의 유입공기의 흐름을 좌?우로 분할되는 형태로 배치되며 그 표면부재는 타공판으로 형성되고 그 내부에는 흡음재가 충진된다.Splitter 19 is provided in the upper portion of the distributor is arranged in the form of dividing the flow of inlet air in the duct 13 left and right, the surface member is formed of a perforated plate and the sound absorbing material is filled therein.

수직과 수평의 덕트(13)가 교차되는 지점에서 1차적으로 소음이 저감된 유입공기는 수평덕트에 일정간격 마다 구비되어 차량의 실내로 유입공기를 배출하는 분배기의 상부에 형성된 스플리터(19)에 의하여 2차적으로 소음이 저감된다.At the point where the vertical and horizontal ducts 13 intersect, the inflow air, which is primarily reduced in noise, is provided in the horizontal duct at regular intervals to the splitter 19 formed in the upper part of the distributor which discharges the intake air into the interior of the vehicle. By this, the noise is secondarily reduced.

소음에 대한 규제는 갈수록 강화되고 있어서 차량의 실내에서 더욱 낮은 소음이 요구되고 있다.Regulations on noise are increasingly tightened, requiring lower noise levels inside the vehicle.

도 5에 도시된 소음기는 송풍기(1)에서 공기가 유출되는 아웃렛(5)에만 설치되었다. 이 경우 아웃렛(5)을 통하여 실내로 유입되는 소음은 저감할 수 있었다. 그런데 송풍기(1)에서 발생한 소음은 아웃렛(5)을 통하여 차량의 실내로 유입될 뿐만 아니라 송풍기(1)로 공기가 유입되는 인렛(6)을 통하여도 차량의 실내로 유입된다. 따라서 소음기가 아웃렛(5)에 설치된 경우 인렛(6)을 통하여 유입되는 소음을 저감시키지 못하므로 실내의 소음을 저감시키는데 한계가 있다는 문제점이 있었다.The silencer shown in FIG. 5 is installed only in the outlet 5 through which air flows out of the blower 1. In this case, the noise flowing into the room through the outlet 5 could be reduced. However, the noise generated by the blower 1 is not only introduced into the interior of the vehicle through the outlet 5, but also into the interior of the vehicle through the inlet 6 through which air is introduced into the blower 1. Therefore, when the silencer is installed in the outlet 5, there is a problem in that there is a limit to reduce the noise in the room because it does not reduce the noise flowing through the inlet (6).

본 발명은 상기의 문제점을 해결하기 위한 것이다. 본 발명은 인렛(6)을 통하여 유입되는 소음을 줄여서 차량의 낮아진 실내 소음 규정을 만족할 수 있는 철도차량용 에어컨덕트 소음기를 제공하는 것을 목적으로 한다.The present invention is intended to solve the above problems.

도 1 내지 도 4를 참조하여 본 발명에 따른 철도차량용 에어컨덕스 소음기의 일 실시예에 대하여 설명한다.An embodiment of an air conditioner duck silencer for a railway vehicle according to the present invention will be described with reference to FIGS. 1 to 4.

본 발명에 따른 철도차량용 에어컨덕트 소음기의 일 실시예는 중간안내깃(15)과, 하부안내깃(14)과, 제1스플리터(19)와, 제2스플리터(21)와, 제3스플리터(27)를 포함한다.One embodiment of the air conditioner duct silencer for a railway vehicle according to the present invention is the intermediate guide vane 15, the lower guide vane 14, the first splitter 19, the second splitter 21, and the third splitter ( 27).

중간안내깃(15)과, 하부안내깃(14)과, 제1스플리터(19)는 송풍기(1)에서 공기가 유출되는 아웃렛(5)에 설치되어 아웃렛(5)을 통과하는 소음을 저감시키는 역할을 하며, 도 5에 도시된 종래의 실시예와 동일하므로 자세한 설명은 생략한다.The intermediate guide feather 15, the lower guide feather 14, and the first splitter 19 are installed in the outlet 5 through which air flows from the blower 1 to reduce noise passing through the outlet 5. It plays a role and is the same as the conventional embodiment shown in FIG.

제2스플리터(21)는 에어컨의 쿨러로 공기가 들어가는 인렛(6)에 설치되어 인렛(6)에서 방출되는 소음을 줄이는 역할을 한다. 이를 위하여 제2스플리터(21)는 제1스플리터(19)와 마찬가지로 흡음재가 충진된 타공판으로 형성되며, 좌측벽부(22)와, 우측벽부(24)와, 전면차단부(26)를 구비한다. 좌측벽부(22)는 인렛(6)의 유입구(7)의 좌측에 위치하고, 우측벽부(24)는 인렛(6)의 유입구(7)의 우측에 위치하며, 전면차단부(26)는 일단은 좌측벽부(22)에 연결되고 타단은 우측벽부(24)에 연결되어 인렛(6)의 유입구(7)전방에 위치한다. 즉 제2스플리터(21)는 인렛(6)의 유입구(7)로 소음이 흘러나가는 것을 방지하도록 유입구(7)를 삼면에서 감싼다. 이때 전면차단부(26)는 상부가 인렛(6)의 유입구(7) 방향으로 경사져서 형성되는 것이 바람직하다. 이로인하여 인렛(6)에서 유입구(7)로 소음이 흘러나가는 길목에 제2스플리터(21)가 설치되어 있으므로 소음이 유입구(7)로 흘러나가는 것을 줄일 수 있다.The second splitter 21 is installed in the inlet 6 into which air enters the cooler of the air conditioner, and serves to reduce noise emitted from the inlet 6. To this end, the second splitter 21 is formed of a perforated plate filled with a sound absorbing material similarly to the first splitter 19, and includes a left wall portion 22, a right wall portion 24, and a front blocking portion 26. The left wall part 22 is located on the left side of the inlet 7 of the inlet 6, the right wall part 24 is located on the right side of the inlet 7 of the inlet 6, and the front blocking part 26 is It is connected to the left wall portion 22 and the other end is connected to the right wall portion 24 is located in front of the inlet (7) of the inlet (6). That is, the second splitter 21 wraps the inlet 7 at three sides to prevent noise from flowing out into the inlet 7 of the inlet 6. At this time, the front blocking portion 26 is preferably formed by inclining the upper portion in the inlet (7) direction of the inlet (6). As a result, since the second splitter 21 is installed on the way from which the noise flows from the inlet 6 to the inlet 7, the flow of the noise to the inlet 7 can be reduced.

제3스플리터(27)는 인렛(6)의 내벽에 설치되어 소음이 인렛(6)을 통하여 외부로 흘러나가는 것을 줄여준다. 이를 위하여 제3스플리터(27)는 좌측흡수판(28)과 우측흡수판(30)을 구비한다. 제3스플리터(27)는 제1스플리터(19) 및 제2스플리터(21)와 마찬가지로 흡음재가 충진된 타공판으로 구성된다. 좌측흡수판(28)은 좌측벽부(22)의 좌측에 위치하는 인렛(6)의 좌측벽에 설치된다. 우측흡수판(30)은 우측벽부(24)의 우측에 위치하는 인렛(6)의 우측벽에 설치된다. 좌측흡수판(28) 및 우측흡수판(30)은 소음이 인렛(6)의 좌측벽과 우측벽에 부딪치어 인렛(6)의 유입구(7)로 방출되는 것을 방지하여 준다. 즉 인렛(6)의 좌측벽과 우측벽에 설치되어 인렛(6)의 좌측벽과 우측벽에 부딪치는 소음을 흡수하여 유입구(7)로 방출하는 것을 방지시킨다.The third splitter 27 is installed on the inner wall of the inlet 6 to reduce the noise flowing out through the inlet 6. To this end, the third splitter 27 includes a left absorbing plate 28 and a right absorbing plate 30. Like the first splitter 19 and the second splitter 21, the third splitter 27 is formed of a perforated plate filled with a sound absorbing material. The left absorbent plate 28 is provided on the left side wall of the inlet 6 located on the left side of the left side wall portion 22. The right absorbent plate 30 is provided on the right side wall of the inlet 6 located on the right side of the right side wall part 24. The left absorbent plate 28 and the right absorbent plate 30 prevent noise from colliding with the left and right walls of the inlet 6 and being discharged to the inlet 7 of the inlet 6. That is, it is installed on the left and right walls of the inlet 6 to absorb the noise hitting the left and right walls of the inlet 6 to prevent the discharge to the inlet (7).

도 4는 본 실시예의 사일런스의 성능을 실험한 실험예이다. 점선(Without Silencer)의 그래프는 제2스플리터(21) 및 제3스플리터(27)가 설치되지 아니한 경우 소음을 실험한 예이고, Type1의 그래프는 제2스플리터(21)가 설치된 경우의 소음을 실험한 예이며, Type2의 그래프는 제2스플리터(21) 및 제3스플리터(27) 모두가 설치된 경우의 소음을 실험한 예이다.4 is an experimental example in which the performance of the silencer of the present embodiment was tested. The graph of the dotted line (Without Silencer) is an example of the noise experiment when the second splitter 21 and the third splitter 27 is not installed, the graph of Type1 is the noise experiment when the second splitter 21 is installed As an example, the graph of Type 2 is an example of experimenting with noise when both the second splitter 21 and the third splitter 27 are installed.

즉 도 4에서 알 수 있듯이 제2스플리터(21)를 설치하면 소음이 훨씬 감소하며, 제3스플리터(27)를 더 설치하면 소음이 더욱 감소함을 알 수 있다.That is, as shown in FIG. 4, the noise is much reduced when the second splitter 21 is installed, and the noise is further reduced when the third splitter 27 is further installed.
