Description

터보차저용 컴프레서 하우징Compressor housing for turbocharger
본 발명은 터보차저에 관한 것으로서, 보다 상세하게는, 터보차저용 컴프레서 하우징에 관한 것이다.The present invention relates to a turbocharger, and more particularly, to a compressor housing for a turbocharger.
자동차 등에 장착되는 내연기관에 관하여는 터보차저(turbo charger)에 관한 기술이 있다. 터보차저란 일반적으로 연소 후에 버려지는 배기가스를 구동동력으로 재활용하는 장치로, 실린더 내에 고밀도의 압축공기를 공급하여, 엔진의 성능(출력, 토크)을 향상시켜, 연료 소비효율을 개선시키고 엔진 경량화(downsizing)에 필수적인 장치이다.There is a technology related to a turbocharger with respect to an internal combustion engine installed in a vehicle or the like. A turbocharger is a device that recycles exhaust gas that is generally thrown away after combustion as a driving power. It supplies high-density compressed air into the cylinder to improve engine performance (output, torque), thereby improving fuel consumption efficiency and reducing engine weight. (downsizing) is an essential device.
터보차저는 터빈 휠(turbine wheel), 터빈 하우징(turbin housing), 컴프레서 휠(compressor wheel), 컴프레서 하우징(compressor housing) 및 센터 하우징(center housing)등으로 이루어져 있고, 터빈 휠과 컴프레서 휠은 배기경로의 중간지점에 마련된 센터 하우징을 매개로 하여, 센터 하우징 내에 회전 가능하게 설치된 샤프트(shaft)를 통하여 동축으로(coaxially) 연결되어 있다.A turbocharger consists of a turbine wheel, a turbine housing, a compressor wheel, a compressor housing, and a center housing, and the turbine wheel and the compressor wheel are exhaust paths It is connected coaxially through a shaft rotatably installed in the center housing through the center housing provided at the midpoint of the .
터보차저에 있어서, 내연기관으로부터 방출된 배기가스는 배기 가스를 유입하는 터빈 하우징 내로 흘러 들어가고, 이 배기가스는 소용돌이 형태로 스크롤 경로(scroll passage)를 따라서 흐른다. 그 후 스크롤 경로로부터 노즐 경로로 흐르고, 터빈 휠에 부딪혀서 터빈 휠을 회전시킨다.In a turbocharger, exhaust gas discharged from an internal combustion engine flows into a turbine housing that introduces the exhaust gas, and the exhaust gas flows along a scroll passage in a vortex shape. It then flows from the scroll path to the nozzle path and hits the turbine wheel to rotate the turbine wheel.
터빈 휠이 이렇게 회전하면 터빈 휠의 토크(torque)가 터빈 축(turbine shaft)을 통하여 컴프레서 휠에 전달되고, 컴프레서 휠은 터빈 휠과 동기적(synchronism)으로 회전한다. 이 때 흡입공기 입구 근처의 흡입공기는 컴프레서 휠의 회전에 의해 발생한 흡입력에 의해 컴프레서 하우징으로 빨려 들어가고, 방출경로(sent-out passage)와 스크롤 경로를 통하여 흡입공기 출구로 보내어진다.When the turbine wheel rotates in this way, the torque of the turbine wheel is transmitted to the compressor wheel through a turbine shaft, and the compressor wheel rotates synchronously with the turbine wheel. At this time, the intake air near the intake air inlet is sucked into the compressor housing by the suction force generated by the rotation of the compressor wheel, and is sent to the intake air outlet through the sent-out passage and the scroll path.
컴프레서 하우징에서 압축된 흡입공기는 강제적으로 연소실로 공급되어, 흡입공기의 충전효율은 향상된다. 이러한 과정에서, 연료 주입량은 흡입 공기량에 따라서 증가하게 되고, 이에 의해 더 큰 연소력(combustionpower)과 폭발력을 얻을 수 있어 엔진출력이 향상된다.The intake air compressed in the compressor housing is forcibly supplied to the combustion chamber, and the intake air charging efficiency is improved. In this process, the fuel injection amount is increased according to the intake air amount, whereby greater combustion power and explosive power can be obtained, thereby improving engine output.
그러나, 컴프레서 하우징의 내부에서는 흡입 공기, 즉 유체의 흐름에 따라 소음이 발생되는 문제가 있다.However, there is a problem in that noise is generated according to the flow of intake air, that is, a fluid inside the compressor housing.
본 발명은 상기와 같은 문제점을 해결하기 위한 것으로서, 소음을 저감하기 위한 터보차저용 컴프레서 하우징을 제공하고자 한다.An object of the present invention is to solve the above problems, and to provide a compressor housing for a turbocharger for reducing noise.
본 발명의 과제들은 이상에서 언급한 과제들로 제한되지 않으며, 언급되지 않는 또 다른 과제들은 아래의 기재로부터 당업자에게 명확하게 이해될 수 있을 것이다.The problems of the present invention are not limited to the problems mentioned above, and other problems not mentioned will be clearly understood by those skilled in the art from the following description.
상기 과제를 해결하기 위하여, 본 발명의 실시예에 따른 터보차저용 컴프레서 하우징은, 터보차저용 컴프레서 하우징에 있어서, 유체가 유입되는 유입부; 및 상기 유입부의 내측면에 탈착 가능하게 결합되는 어댑터를 포함하되, 상기 어댑터의 내측면에는 유체의 흐름에 의해 발생되는 소음을 저감하기 위한 소음 저감 홈이 형성될 수 있다.In order to solve the above problems, a compressor housing for a turbocharger according to an embodiment of the present invention includes: an inlet into which a fluid is introduced; and an adapter detachably coupled to the inner surface of the inlet, wherein a noise reduction groove for reducing noise generated by the flow of a fluid may be formed on the inner surface of the adapter.
이 때, 상기 유입부의 내측면에는 제1 나사산이 형성되고, 상기 어댑터의 외측면에는 상기 제1 나사산에 대응되는 제2 나사산이 형성되고, 상기 제2 나사산이 상기 제1 나사산을 따라 시계 방향 또는 반시계 방향으로 회전됨에 따라, 상기 어댑터는 상기 유입부의 내측면에 결합되거나 분리될 수 있다.In this case, a first screw thread is formed on the inner surface of the inlet part, and a second screw thread corresponding to the first screw thread is formed on the outer surface of the adapter, and the second screw thread is rotated in a clockwise direction or along the first screw thread. As it rotates counterclockwise, the adapter may be coupled to or separated from the inner surface of the inlet.
이 때, 상기 소음 저감 홈의 단면은 사다리꼴 형상으로 이루어질 수 있다.In this case, the cross section of the noise reduction groove may be formed in a trapezoidal shape.
이 때, 상기 소음 저감 홈의 단면은, 경사면; 상기 경사면으로부터 연장되고, 상기 어댑터의 내측면과 나란하게 형성되는 수평면; 및 상기 수평면으로부터 실질적으로 수직한 방향으로 연장되는 수직면을 포함할 수 있다.At this time, the cross-section of the noise reduction groove, the inclined surface; a horizontal surface extending from the inclined surface and formed parallel to the inner surface of the adapter; and a vertical plane extending in a substantially vertical direction from the horizontal plane.
이 때, 상기 경사면은 곡면으로 이루어질 수 있다.In this case, the inclined surface may be formed of a curved surface.
본 발명의 실시예에 따른 터보차저용 컴프레서 하우징은, 소음 저감 홈에 의해 소음이 저감되는 이점이 있다.The compressor housing for a turbocharger according to an embodiment of the present invention has an advantage in that noise is reduced by the noise reduction groove.
또한, 어댑터가 유입부의 입구부에 탈착 가능하게 결합되므로, 특정 주파수의 소음에 따라 맞춤형 소음 저감 홈이 형성된 어댑터를 장착하게 되므로, 전체 컴프레서 하우징을 교체하지 않게 되어 비용을 절감할 수 있다.In addition, since the adapter is detachably coupled to the inlet portion of the inlet, the adapter having a custom noise reduction groove formed according to the noise of a specific frequency is mounted, thereby reducing the cost by not replacing the entire compressor housing.
또한, 소음을 저감하면서도 터보차저의 출력 성능이 저하되는 것을 방지한다.In addition, while reducing noise, the output performance of the turbocharger is prevented from being deteriorated.

도 1 내지 도 6을 참조하면, 본 발명의 실시예에 따른 터보차저용 컴프레서 하우징(100)은 유입부(110), 배출부(120) 및 어댑터(150)를 포함한다.1 to 6 , the compressor housing 100 for a turbocharger according to an embodiment of the present invention includes an inlet 110 , an outlet 120 , and an adapter 150 .
상기 유입부(110)에는 유체가 유입되는 유입구(111)가 형성된다. 상기 유입구(111)는 원통 형상으로 이루어진다. 상기 유입부(110)의 내측면에는 제1 나사산(112)이 형성된다. 그리고, 상기 유입부(110)의 내측면에는 상기 제1 나사산(112)과 이격되어 형성되는 단차부(113)가 형성된다.An inlet 111 through which a fluid is introduced is formed in the inlet 110 . The inlet 111 has a cylindrical shape. A first screw thread 112 is formed on the inner surface of the inlet 110 . In addition, a step portion 113 formed to be spaced apart from the first screw thread 112 is formed on the inner surface of the inlet portion 110 .
상기 배출부(120)는 상기 유입부(110)를 통해 유입되어 상기 터보차저용 컴프레서 하우징(100)을 통해 압축된 유체가 배출된다. 상기 배출부(120)를 통해 배출되는 압축된 유체가 엔진(미도시)으로 공급됨에 따라, 엔진 출력이 향상된다.The discharge unit 120 is introduced through the inlet unit 110 and the compressed fluid is discharged through the turbocharger compressor housing 100 . As the compressed fluid discharged through the discharge unit 120 is supplied to an engine (not shown), engine output is improved.
상기 어댑터(150)는 상기 유입부(110)의 내측면에 탈착 가능하게 결합된다. 상기 어댑터(150)는 대략적으로 원통 형상으로 이루어진 어댑터 바디(151)를 포함한다. 상기 어댑터 바디(151)는 상기 유입구(111)의 형상과 대응되도록 형성된다.The adapter 150 is detachably coupled to the inner surface of the inlet 110 . The adapter 150 includes an adapter body 151 having an approximately cylindrical shape. The adapter body 151 is formed to correspond to the shape of the inlet 111 .
상기 어댑터 바디(151)의 외측면에는 상기 제1 나사산(112)에 대응되는 제2 나사산(152)이 형성된다. 상기 제2 나사산(152)이 상기 제1 나사산(112)을 따라 시계 방향 또는 반시계 방향으로 회전됨에 따라, 상기 어댑터(150)는 상기 유입부(110)의 내측면에 결합되거나 분리된다. A second screw thread 152 corresponding to the first screw thread 112 is formed on the outer surface of the adapter body 151 . As the second screw thread 152 is rotated clockwise or counterclockwise along the first screw thread 112 , the adapter 150 is coupled to or disconnected from the inner surface of the inlet 110 .
또한, 상기 어댑터 바디(151)의 일단(153)은 상기 단차부(113)와 대응되도록 형성되고, 상기 단차부(113)에 접촉한다. 이에 따라, 상기 어댑터 바디(151)의 내부를 따라 유입된 유체가 상기 어댑터 바디(151)의 외측면과 상기 유입부(110)의 내측면 사이에 이동되는 것이 방지되므로, 상기 엔진의 출력이 저하되는 것이 방지된다.In addition, one end 153 of the adapter body 151 is formed to correspond to the stepped portion 113 and is in contact with the stepped portion 113 .

상기 어댑터(150)의 내측면에는 유체의 흐름에 의해 발생되는 소음을 저감하기 위한 소음 저감 홈(155)이 형성된다.A noise reduction groove 155 for reducing noise generated by the flow of a fluid is formed on the inner surface of the adapter 150 .
상기 소음 저감 홈(155)의 단면(154)은, 사다리꼴 형상으로 이루어질 수 있다. 또한, 소음 저감 홈(155)의 단면(154)은, 도 5에 도시된 바와 같이, 경사면(154a), 수평면(154b) 및 수직면(154c)을 포함한다.A cross section 154 of the noise reduction groove 155 may have a trapezoidal shape. In addition, the cross section 154 of the noise reduction groove 155, as shown in FIG. 5, includes an inclined surface 154a, a horizontal surface 154b, and a vertical surface 154c.
상기 경사면(154a)은 상기 어댑터(150)의 내측면(151a)으로부터 제1 각도(θ1)를 가지도록 형성된다. 여기서, 상기 제1 각도(θ1)는 예각이다.The inclined surface 154a is formed to have a first angle θ1 from the inner surface 151a of the adapter 150 . Here, the first angle θ1 is an acute angle.
상기 수평면(154b)은 상기 경사면(154a)으로부터 연장된다. 상기 수평면(154b)은 상기 어댑터(150)의 내측면(151a)과 나란하게 형성된다. The horizontal surface 154b extends from the inclined surface 154a. The horizontal surface 154b is formed parallel to the inner surface 151a of the adapter 150 .
상기 수직면(154c)은 상기 수평면(154b)으로부터 실질적으로 수직한 방향으로 연장된다. 즉, 상기 수직면(154c)은 상기 수평면(154b)으로부터 제2 각도(θ2)를 가지도록 형성된다. 이 때, 상기 제2 각도(θ2)는 90 ° 일 수 있다.The vertical plane 154c extends in a substantially vertical direction from the horizontal plane 154b. That is, the vertical plane 154c is formed to have a second angle θ2 from the horizontal plane 154b. In this case, the second angle θ2 may be 90°.
상기 유입구(111)를 통해 유입된 유체가 상기 경사면(154a)을 따라 이동되면, 특정 주파수의 소음이 저감된다. 그리고, 상기 경사면(154a)을 따라 이동된 유체는 상기 수직면(154c)을 경유함에 따라, 엔진의 출력이 저감되는 것이 방지된다.When the fluid introduced through the inlet 111 moves along the inclined surface 154a, noise of a specific frequency is reduced. And, as the fluid moved along the inclined surface 154a passes through the vertical surface 154c, it is prevented that the output of the engine is reduced.
이 때, 상기 경사면은 특정 주파수의 소음을 저감하기 위해 다양한 제1 각도(θ1)를 가지도록 형성될 수 있다. 그리고, 상기 소음 저감 홈(155)은 특정 주파수의 소음을 저감하기 위해 다양한 크기의 부피를 가지도록 형성될 수 있다.In this case, the inclined surface may be formed to have various first angles θ1 in order to reduce noise of a specific frequency. In addition, the noise reduction groove 155 may be formed to have a volume of various sizes in order to reduce noise of a specific frequency.
또한, 전술한 바와 같이, 상기 어댑터(150)가 상기 유입부(110)의 내측면에 탈착 가능하게 결합됨에 따라, 특정 주파수의 소음을 저감하기 위해서 전체 터보차저용 컴프레서 하우징 전체를 교체하지 않고, 다양한 경사면과 다양한 부피를 가지는 소음 저감 홈이 형성된 어댑터를 장착할 수 있다In addition, as described above, as the adapter 150 is detachably coupled to the inner surface of the inlet 110, in order to reduce noise at a specific frequency, the entire turbocharger compressor housing is not replaced. Adapters with various slopes and noise reduction grooves with various volumes can be installed

도 7을 참조하면, 본 발명의 다른 실시예에 따른 어댑터에는 소음 저감 홈(155')이 형성된다. 이 때, 상기 소음 저감 홈(155')의 단면(154')은 경사면(154a'), 수평면(154b') 및 상기 수직면(154c')을 포함하고, 전술한 실시예의 구성요소와 동일하거나 유사한 구성요소에 대한 설명은 전술한 설명으로 대체하고, 경사면(154a')을 중점적으로 살펴보기로 한다.Referring to FIG. 7 , a noise reduction groove 155 ′ is formed in the adapter according to another embodiment of the present invention. At this time, the cross section 154' of the noise reduction groove 155' includes an inclined surface 154a', a horizontal surface 154b', and the vertical surface 154c', and is the same as or similar to the components of the above-described embodiment. The description of the components will be replaced with the above description, and the inclined surface 154a' will be focused on.
상기 경사면(154a')은 곡면으로 이루어진다. 이에 따라, 상기 유입구(111, 도 1 참조)를 통해 유입된 유체가 상기 경사면(154a')을 따라 이동되면, 특정 주파수의 소음이 저감된다. 그리고, 상기 경사면(154a')을 따라 이동된 유체는 상기 수직면(154c')을 경유함에 따라, 엔진의 출력이 저감되는 것이 방지된다.The inclined surface 154a' is formed of a curved surface. Accordingly, when the fluid introduced through the inlet 111 (refer to FIG. 1 ) moves along the inclined surface 154a', noise of a specific frequency is reduced. And, as the fluid moved along the inclined surface 154a' passes through the vertical surface 154c', it is prevented that the output of the engine is reduced.
