차량의 실제 구동력이 발생되는 엔진에서는, 화학에너지를 운동에너지로 바꾸는 과정에서 많은 열에너지가 발생된다. 이러한 열에너지가 과도하게 발생되면, 엔진 및/또는 엔진 주변의 부품들이 과열됨으로써 손상 또는 파괴되어 큰 고장과 사고로 이어질 가능성이 있으며, 또한 엔진 자체의 효율도 크게 떨어지게 되는 등 여러 가지 문제점이 생긴다. 따라서 이러한 문제 요인을 제거하기 위하여 통상적으로 차량에는 엔진을 냉각하기 위한 장치가 구비된다. 엔진의 냉각을 위해서 대표적으로 사용되는 방법은 냉각수를 이용하는 방법으로써, 엔진의 주변에 냉각수를 유통시키고 또한 냉각수를 냉각시키기 위한 라디에이터(radiator)를 구비하여, 엔진에서 발생되는 열을 흡수한 후 흡수된 열을 라디에이터에서 방출함으로써 엔진의 과열을 막는다. 또한, 차량 운전자 및 탑승자의 쾌적성을 위하여 실내를 냉방하기 위한 장치도 함께 구비되고 있다. 이러한 실내 냉방을 위한 에어컨의 냉매를 냉각하기 위하여 응축기(condenser)와 같은 열교환기가 사용된다.In an engine in which the actual driving force of the vehicle is generated, a lot of heat energy is generated in the process of converting chemical energy into kinetic energy. When such heat energy is excessively generated, there is a possibility that the engine and / or parts around the engine may be overheated, damaged or destroyed, leading to major failures and accidents, and the efficiency of the engine itself may be greatly reduced. Therefore, in order to eliminate this problem factor, the vehicle is usually equipped with a device for cooling the engine. The typical method for cooling the engine is to use coolant, which is provided with a radiator for distributing the coolant around the engine and cooling the coolant. By radiating heat from the radiator, it prevents the engine from overheating. In addition, a device for cooling the room is also provided for the comfort of the vehicle driver and the occupant. A heat exchanger such as a condenser is used to cool the refrigerant of the air conditioner for indoor cooling.
차량의 엔진룸 전방에는 상술한 바와 같은 라디에이터나 응축기 등의 열교환기들이 구비되며, 상기 열교환기들에서는 주변의 공기와 열교환기 내부의 열교환매체 사이에 열교환이 발생된다. 이 때, 상기 열교환기의 방열 효율을 높이기 위하여 상기 열교환기에 대해 공기를 강제 송풍할 수 있는 축류팬이 설치된다.Heat exchangers such as radiators and condensers are provided in front of the engine room of the vehicle, and the heat exchangers are generated between the surrounding air and the heat exchange medium inside the heat exchanger. At this time, in order to increase the heat dissipation efficiency of the heat exchanger, an axial fan capable of forcibly blowing air to the heat exchanger is installed.
축류팬은 일반적으로 쉬라우드 내에 수용 구비되며, 쉬라우드에 축류팬을 회전시키기 위한 모터 등이 고정되고, 또한 쉬라우드가 마운팅 되어 그 위치가 고정된다. 이와 같이 축류팬, 쉬라우드, 모터 등이 이루는 축류팬 조립체가 열교환기 또는 엔진 룸 바닥에 마운팅 되어 열교환기 전방 또는 후방에 배치되게 된다. The axial fan is generally accommodated in the shroud, and a motor or the like for rotating the axial fan is fixed to the shroud, and the shroud is mounted to fix its position. As such, the axial fan assembly formed by the axial fan, the shroud, the motor, and the like is mounted on the heat exchanger or the engine room floor to be disposed at the front or rear of the heat exchanger.

상기 열교환기에 인접된 반대편에 해당하는 쉬라우드(20)의 단부에는 일정한 곡률로 만곡된 벨마우스(21)가 일체로 형성되어 있고, 상기 허브에 회전축이 결합되는 모터(11)는 별도의 모터 마운팅부(22)에 의해 마운팅 되어 고정되어 있다. At the end of the shroud 20 corresponding to the other side adjacent to the heat exchanger, a bell mouse 21 curved at a constant curvature is integrally formed, and the motor 11 coupled to the hub has a separate motor mounting.

이하, 상술한 바와 같은 본 발명에 따른 팬쉬라우드 조립체를 첨부된 도면을 참조로 상세히 설명한다.Hereinafter, the fan shroud assembly according to the present invention as described above will be described in detail with reference to the accompanying drawings.
도 3에 도시된 바와 같이, 본 발명에 따른 팬쉬라우드 조립체(1)는 크게 팬(150) 및 쉬라우드(160)로 구성된다.As shown in FIG. 3, the fan shroud assembly 1 according to the present invention is largely composed of a fan 150 and a shroud 160.
먼저, 상기 팬(150)은 모터(110)에 의해 회전하면서 차량의 열교환기에 송풍 공기를 전달하는 회전 팬으로, 허브(120), 블레이드(130) 및 팬밴드(140)를 포함하여 형성되고, 상기 쉬라우드(160)는 벨마우스(200), 모터마운팅(300) 및 스테이터(400)를 포함하여 형성된다.First, the fan 150 is a rotary fan that delivers blowing air to the heat exchanger of the vehicle while rotating by the motor 110, is formed including a hub 120, a blade 130 and a fan band 140, The shroud 160 is formed to include a bell mouse 200, a motor mounting 300, and a stator 400.
먼저, 상기 벨마우스(200)는 팬(150)에 의해 공기가 송풍되도록 플래넘부의 중앙 일정영역이 중공된 공간인 송풍부(100)를 형성한다.First, the bell mouse 200 forms a blower 100 in which a central predetermined region of the plenum is hollow so that air is blown by the fan 150.
상기 모터마운팅(300)은 상기 팬(150)을 구동하기 위한 모터가 마운팅 되는 부분으로서, 송풍부(100)의 중앙 영역에 위치된다.The motor mounting 300 is a portion in which a motor for driving the fan 150 is mounted, and is located in the central region of the blower 100.
상기 스테이터(400)는 팬의 차량 전방측면에서 상기 모터마운팅(300)과 벨마우스(200)를 연결하는 부재로서, 상기 모터마운팅(300)의 외주면으로부터 상기 벨마우스(200)의 내주면을 연결하도록 형성되며, 상기 벨마우스(200)의 둘레를 따라 복수개 형성되어 상기 팬(150)으로부터 송풍된 공기의 유입각 및 토출각을 제어하게 된다.The stator 400 is a member for connecting the motor mounting 300 and the bell mouse 200 on the vehicle front side of the fan, so as to connect the inner circumferential surface of the bell mouse 200 from the outer circumferential surface of the motor mounting 300. It is formed, a plurality is formed along the circumference of the bell mouse 200 to control the inflow and discharge angle of the air blown from the fan 150.
특히, 상기 쉬라우드(160)는 상기 송풍부(100)의 내주면 일정영역을 따라 상기 팬(150)의 블레이드(130) 단부, 또는 상기 팬(150)의 팬밴드(140) 단부와 일정 간극을 유지하며 배열되고, 톱니 형태로 형성되는 와류방지톱니(500)를 더 포함하여 형성되되, 일부 영역에만 와류방지톱니(500)가 형성되어 상기 와류방지톱니(500)가 형성되지 않은 영역이 존재하게 된다.In particular, the shroud 160 has a predetermined gap with an end portion of the blade 130 of the fan 150 or the end of the fan band 140 of the fan 150 along a predetermined region of the inner circumferential surface of the blower 100. It is formed while maintaining, and further comprises a vortex preventing tooth 500 is formed in a sawtooth shape, the vortex preventing tooth 500 is formed only in a portion of the area so that the vortex preventing tooth 500 is not formed do.
즉, 상기 쉬라우드(160)는 상기 와류방지톱니(500)가 형성되는 영역이 한 개일 경우 원주방향으로 양측 단부가 서로 이격되며, 상기 와류방지톱니(500)가 형성되는 영역이 다수개일 경우 원주방향으로 이웃한 영역의 단부와 서로 이격되어 형성된다.That is, the shroud 160 is spaced apart from each other in the circumferential direction when there is only one region in which the vortex preventing teeth 500 are formed, and the circumference when the vortex preventing teeth 500 is formed in plural regions. It is formed spaced apart from each other with the end of the adjacent region in the direction.
참고로, 상기 블레이드(130)는 상기 팬(150)의 중앙부에 형성되는 허브의 원주에 방사상으로 복수개 배치되는 구성으로서, 공기를 축방향으로 이송한다.For reference, the blade 130 is a plurality of radially arranged on the circumference of the hub formed in the central portion of the fan 150, and conveys the air in the axial direction.
또한, 상기 팬밴드(150)는 상기 블레이드(130)의 단부를 서로 연결하여 형성되며, 전체적으로 링 형태로 형성되는 것을 말한다.In addition, the fan band 150 is formed by connecting the ends of the blade 130 to each other, and refers to being formed in a ring shape as a whole.
즉, 상기 쉬라우드(160)는 상기 송풍부(100)의 내주면을 따라 전 영역에 와류방지톱니(500)가 형성되는 것이 아니라, 상기 송풍부(100)의 중심부로부터 반경방향으로 연장된 반경선(R1)을 중심으로 일정 각도 내에는 와류방지톱니(500)가 형성되지 않고, 나머지 영역에만 형성된다.That is, the shroud 160 is not formed in the entire region along the inner circumferential surface of the blower 100, the vortex preventing teeth 500, a radial line extending radially from the center of the blower 100 The vortex preventing teeth 500 are not formed within a predetermined angle with respect to the R1, and are formed only in the remaining area.
이는 상기 와류방지톱니(500)가 상기 송풍부(100)의 내주면을 따라 전 영역에 형성될 경우, 상기 벨마우스(200)와 쉬라우드(160)의 외측 가장자리 사이 공간이 좁아지는 부분인 상기 벨마우스(200)의 상단 및 하단 영역에서 톱니 형상에 의해 오히려 유동의 압력 변동이 증가하게 되는 문제점을 개선하기 위한 것이다.This is the bell which is the portion where the space between the outer edge of the bell mouse 200 and the shroud 160 is narrowed when the vortex preventing teeth 500 are formed in the entire area along the inner circumferential surface of the blower 100. In order to improve the problem that the pressure fluctuation of the flow is increased by the sawtooth shape in the upper and lower regions of the mouse 200.
이때, 상기 반경선(R1)은 상기 플래넘부(101)의 외측 가장자리 면과, 벨마우스(200) 사이 거리가 최단 거리가 되는 점의 접선과 수직인 선을 의미한다.In this case, the radial line R1 refers to a line perpendicular to the tangent of the point at which the distance between the outer edge surface of the plenum portion 101 and the bell mouse 200 becomes the shortest distance.
따라서 본 발명의 팬쉬라우드 조립체는 일부 영역에 와류방지톱니(500)를 삭제함으로써, 압력변동량이 낮아져 송풍되는 공기의 와류가 발생되고, 이로 인해 소음을 효과적으로 저감할 수 있는 장점이 있다.Therefore, in the fan shroud assembly of the present invention, by removing the vortex preventing teeth 500 in some areas, the pressure fluctuation is lowered, so that the vortex of the air blown is generated, thereby effectively reducing the noise.
이때, 본 발명의 팬쉬라우드 조립체는 상기 와류방지톱니(500)가 형성되는 영역이 제1영역(A1)이고, 상기 와류방지톱니(500)가 형성되지 않아 상기 송풍부(100)의 내주면이 편평하게 형성된 영역을 제2영역(A2)이라 할 때, 상기 제2영역(A2)이 상기 반경선(R1)으로부터 일측 방향으로 θ만큼 이격된 영역과, 타측방향으로 θ′만큼 이격된 영역을 포함하여 형성될 수 있다.At this time, in the fan shroud assembly of the present invention, the region in which the vortex preventing teeth 500 are formed is the first region A1, and the inner circumferential surface of the blower 100 is not formed because the vortex preventing teeth 500 are not formed. When the flatly formed region is referred to as the second region A2, the region where the second region A2 is spaced apart from the radial line R1 by θ in one direction and the region spaced apart by θ ′ in the other direction is formed. It may be formed to include.
다시 말해, 도 3과 같이 본 발명의 팬쉬라우드 조립체는 반경선(R1)을 중심으로 양쪽으로 θ 및 θ′각도 이내의 영역에는 와류방지톱니(500)가 형성되지 않고, 나머지 영역에 와류방지톱니(500)가 형성된다.In other words, as shown in FIG. 3, in the fan shroud assembly of the present invention, the vortex preventing teeth 500 are not formed in the regions within the angles θ and θ ′ on both sides of the radial line R1, and vortex prevention is performed in the remaining regions. Tooth 500 is formed.
이때, 상기 반경선(R1)은 상기 송풍부(100)의 중심부로부터 수직방향으로 연장된 반경선과 일치할 수도 있으며, 상기 송풍부(100)의 중심부로부터 수직방향으로 연장된 반경선이 일정각도 회전된 상태일 수도 있다.At this time, the radial line (R1) may coincide with the radial line extending in the vertical direction from the center of the blower 100, the radial line extending in the vertical direction from the center of the blower 100 is rotated by a predetermined angle. It may be in a closed state.
상기 반경선(R1)은 도 3과 같이 상기 플래넘부(101)가 장방형 또는 정방형으로 형성될 경우에는 수직방향으로 연장된 반경선과 일치하며, 도 9와 같이 상기 플래넘부(101)가 높이방향으로 일측 또는 양측면 일정영역이 단차지어 형성되는 경우에는 수직방향으로 연장된 반경선이 일정각도 회전된 상태가 된다.The radial line R1 corresponds to a radial line extending in the vertical direction when the plenum portion 101 is formed in a rectangle or a square as shown in FIG. 3, and the plenum portion 101 in the height direction as illustrated in FIG. 9. When one side or both side predetermined regions are formed stepped, the radial lines extending in the vertical direction are rotated by a predetermined angle.
이는 도 8에 도시된 바와 같이, 공기 유동의 압력 변동이 상기 벨마우스(200)와 쉬라우드(160)의 플래넘부(101) 외측 가장자리 사이 공간이 좁아지는 부분에서 증가하기 때문이다.This is because, as shown in FIG. 8, the pressure fluctuation of the air flow increases at a portion where the space between the bell mouth 200 and the outer edge of the plenum 101 of the shroud 160 is narrowed.
즉, 장방형 또는 정방형의 플래넘부(101)를 갖는 팬쉬라우드 조립체의 경우 압력 변동이 증가되는 영역이 수직방향 반경선의 양단이 되고, 도 9와 같이 단차지어 형성되는 플래넘부(101)를 갖는 팬쉬라우드 조립체는 압력 변동이 증가되는 영역이 수직방향 반경선으로부터 일정 각도 기울어진 영역의 양단에 위치하게 된다.That is, in the case of the fan shroud assembly having a rectangular or square plenum portion 101, a region in which the pressure fluctuation is increased becomes both ends of the vertical radial line, and a fan having the plenum portion 101 formed stepped as shown in FIG. In the shroud assembly, the region where the pressure fluctuation is increased is located at both ends of the region inclined at an angle from the vertical radial line.
이에 따라, 상술한 바와 같이 본 발명의 팬쉬라우드 조립체는 압력 변동을 최소화하기 위해, 상기 플래넘부(101) 외측 가장자리 사이 공간이 좁아지는 부분에 형성되는 와류방지톱니(500)가 형성되지 않는다.Accordingly, as described above, in order to minimize pressure fluctuations, the fan shroud assembly of the present invention does not have the vortex preventing teeth 500 formed at a portion where the space between the outer edges of the plenum portion 101 is narrowed.
이때, 본 발명의 팬쉬라우드 조립체는 상기 제2영역(A2)이 상기 반경선(R1)의 양측 단부에 인접하여 형성될 수도 있지만, 중력방향으로 상부 또는 하부 영역에만 형성될 수도 있다.In this case, in the fan shroud assembly of the present invention, the second region A2 may be formed adjacent to both ends of the radial line R1, but may be formed only in the upper or lower region in the direction of gravity.
도 7 및 도 8은 쉬라우드(160)에서 수직 방향 반경선(R1)과 인접한 영역에 와류방지톱니(500)가 제거되기 전과 제거된 후를 분석한 유동 특성 분석도에 관한 것이다.7 and 8 relate to flow characteristic analysis diagrams before and after the removal of the vortex preventing teeth 500 in the region adjacent to the vertical radial line R1 in the shroud 160.
도 7에 도시된 바와 같이, 공기 유동의 압력 변동은 상기 벨마우스(200)와 쉬라우드(160)의 플래넘부(101) 외측 가장자리 사이 공간이 좁아지는 부분에서 증가하는 것을 알 수 있다.As shown in FIG. 7, it can be seen that the pressure fluctuation of the air flow increases at a portion where the space between the bell mouth 200 and the outer edge of the plenum 101 of the shroud 160 is narrowed.
반면, 상기 벨마우스(200)와 플래넘부(101)의 외측 가장자리 사이 공간이 좁아지는 부분에 형성된 와류방지톱니(500)를 제거한 경우에는, 도 8과 같이 동일 영역에서 공기 유동의 압력 변동이 감소한 것을 알 수 있다.On the other hand, when the vortex preventing teeth 500 formed at the portion where the space between the bell mouth 200 and the outer edge of the plenum portion 101 is narrowed, the pressure fluctuation of the air flow in the same region as shown in FIG. It can be seen that.
이 때, 상기 벨마우스(200)와 상기 플래넘부(101)의 외측 가장자리 사이 공간이 좁아지는 부분은 상기 송풍부(100)의 수직 방향 반경선(R1)과 인접한 영역으로, 차량 내 장착 공간 제약으로 인해 일반적으로 장방형 또는 정방형으로 형성되는 쉬라우드(160)의 플래넘부(101)의 경우, 동심원인 송풍부(100)의 상단 및 하단과 인접한 영역을 의미하게 된다.At this time, the portion where the space between the bell mouse 200 and the outer edge of the plenum portion 101 becomes narrow is an area adjacent to the vertical radial line R1 of the blower 100, and the installation space of the vehicle is limited. Therefore, in the case of the plenum portion 101 of the shroud 160, which is generally formed in a rectangle or a square, it means an area adjacent to the top and bottom of the concentric blower 100.
도 3과 같이, 상기 와류방지톱니(500)는 상기 송풍부(100)의 상기 반경선(R1)을 중심으로 서로 대칭인 영역에 형성될 수 있다.As shown in FIG. 3, the vortex preventing teeth 500 may be formed in regions symmetrical with respect to the radial line R1 of the blower 100.
다시 말해, 도 3의 A지점을 중심으로 θ만큼 이격된 거리와 θ′만큼 이격된 거리는 서로 동일한 값을 가질 수 있다.In other words, the distance spaced by θ and the distance spaced by θ 'with respect to the point A of FIG. 3 may have the same value.
물론, 상기 팬쉬라우드 조립체는 상기 반경선(R1)으로부터 원주방향으로 양측으로 이격된 각도인 θ와, θ′가 서로 상이할 수도 있으며 그 각도는 다양하게 변경실시가 가능하다.Of course, the fan shroud assembly may be different from each other and θ ', which is an angle θ, spaced apart from both sides in the circumferential direction from the radius line R1, and the angle may be variously changed.
이 때, 상기 쉬라우드(160)는 θ 및 θ′값에 따라 소음 저감 효과가 달라질 수 있는데, 바람직한 θ 및 θ′값을 알아내기 위해 여러 각도로 실험한 결과가 도 5 및 도 6에 도시되었다.In this case, the shroud 160 may have a different noise reduction effect depending on the values of θ and θ ′, and the results of experimenting at various angles to find preferred values of θ and θ ′ are shown in FIGS. 5 and 6. .
도 5(a)는 θ값을 다양한 각도로 변화시키면서, 팬쉬라우드 조립체의 블레이드 전방 1m에서 소음측정기로 측정한 노이즈를 나타낸 것이며, 도 4(b)는 팬쉬라우드 조립체의 노이즈 성분 중 Max. peak noise를 나타낸 것이다.Figure 5 (a) shows the noise measured by the noise meter at 1m in front of the blade of the fan shroud assembly while changing the θ value at various angles, Figure 4 (b) shows the noise component of the fan shroud assembly Max. peak noise is shown.
도 5 및 도6에서 알 수 있듯이, 팬쉬라우드 조립체의 소음은 θ 및 θ′값이 15~20° 일 때, 가장 크게 저감되었다.As can be seen in Figures 5 and 6, the noise of the fan shroud assembly is greatly reduced when the θ and θ 'value is 15 ~ 20 °.
이에 따라, 상기 쉬라우드(160)는 상기 송풍부(100)의 상기 반경선(R1)을 중심으로 15~20° 이격되어 상기 와류방지톱니(500)가 형성되는 것이 바람직하다. 이는 도 6에 도시된 바와 같이, A영역에서 급격한 압력증가로 소음이 증가하기 때문이며, θ 및 θ′값이 15~20° 보다 작거나 크면, 소음이 일정수준 이상으로 증가하게 되므로 상기 와류방지톱니(500)는 θ 및 θ′값이 15~20°인 영역엔 형성되지 않는 것이 바람직하다.Accordingly, the shroud 160 is preferably spaced apart 15 ~ 20 ° with respect to the radial line (R1) of the blower 100 is the vortex preventing teeth 500 is formed. This is because, as shown in Figure 6, the noise increases due to a sudden increase in pressure in the area A, and if the θ and θ 'value is less than or equal to 15 ~ 20 °, the noise is increased to a certain level or more so that the eddy current It is preferable that 500 is not formed in the region whose θ and θ ′ values are 15 to 20 °.
또한, 상기 쉬라우드(160)는 상기 와류방지톱니(500)가 형성되지 않은 영역이인 상기 제2영역(A2)은 상기 송풍부(100)의 수평 방향 반경선(R2)을 중심으로 서로 대칭일 수 있다.In addition, the shroud 160 is an area where the vortex preventing teeth 500 are not formed, and the second area A2 is symmetrical with respect to a horizontal radial line R2 of the blower 100. Can be.
한편, 상기 와류방지톱니(500)는 상기 송풍구의 반경선에 대하여 상기 팬의 회전 방향 쪽의 제1면과 회전 반대 방향 쪽의 제2면을 포함하며, 상기 제1면 또는 상기 제2면은 상기 팬의 반경선과 경사지게 형성되며, 상기 와류방지톱니(500)의 산 또는 골이 상기 팬의 축방향에 나란하게 형성될 수 있다.On the other hand, the vortex preventing teeth 500 includes a first surface on the rotational side of the fan and a second surface on the opposite side of the rotation with respect to the radial line of the tuyeres, and the first surface or the second surface is It is formed to be inclined with the radial line of the fan, the peak or valley of the vortex preventing teeth 500 may be formed side by side in the axial direction of the fan.
도 3 및 도 4를 참고로, 본 발명에 따른 팬쉬라우드 조립체(1)의 작동과정을 설명하면, 상기 팬(150)이 회전하기 시작한 후, 상기 팬(150)의 블레이드(130) 회전에 따른 흡인력에 의해, 열교환기의 전방으로부터 공기가 열교환기 측으로 송풍되어 열교환기가 냉각될 수 있다.Referring to FIGS. 3 and 4, the operation of the fan shroud assembly 1 according to the present invention will be described. After the fan 150 starts to rotate, the blade 130 of the fan 150 rotates. By the suction force, the air is blown from the front of the heat exchanger to the heat exchanger side to cool the heat exchanger.
열교환기를 거친 공기는 상기 쉬라우드(160)의 송풍부(100) 측으로 안내된다. 상기 송풍부(100) 측으로 안내된 공기는 상기 블레이드 사이를 통해 상기 벨마우스(200)에 의해 상기 쉬라우드(160) 후방으로 토출된다.The air passing through the heat exchanger is guided to the blower part 100 side of the shroud 160. The air guided to the blower 100 is discharged to the rear of the shroud 160 by the bell mouse 200 through the blades.
이 때, 상기 블레이드 끝단의 회전에 의해 상기 송풍구의 내주면 쪽에서 공기가 흡입되는 측인 전방에 저압이 형성되고, 공기가 토출되는 측인 후방에 고압이 형성됨에 따라, 후방에서 전방으로 와류를 일으키며 공기가 역류하지만, 상기 쉬라우드(160)가 적용된 팬쉬라우드 조립체에서는 상기 와류방지톱니(500)에 의해 와류 및 역류 발생이 억제되어 소음이 효과적으로 저감된다.At this time, the low pressure is formed in the front of the air inlet side on the inner circumferential surface side of the tuyere by the rotation of the blade end, the high pressure is formed in the rear of the air discharge side, causing vortex from the rear to the front and the air flows backward However, in the fan shroud assembly to which the shroud 160 is applied, eddy current and backflow are suppressed by the vortex preventing teeth 500, and noise is effectively reduced.
또한, 상기 벨마우스(200)와 쉬라우드(160)의 외측 가장자리 사이 공간이 좁아지는 부분에서도, 유동 압력에 큰 변동이 발생되지 않아 상기 와류방지톱니(500)가 상기 송풍부(100) 내주면 전체에 형성되는 것보다 소음 저감 효과가 증대될 수 있다.In addition, even in a portion where the space between the outer edges of the bell mouse 200 and the shroud 160 is narrowed, large fluctuations in the flow pressure do not occur, so that the vortex preventing teeth 500 have the entire inner circumferential surface of the blower 100. Noise reduction effect can be increased than that formed in the.
즉, 상기 쉬라우드(160)는 와류방지톱니(500)를 통해 팬의 회전에 의한 공기 송풍시 와류 및 역류 발생을 억제하여 소음을 저감시키되, 벨마우스(200)와 쉬라우드(160)의 외측 가장자리 사이 공간이 좁아지는 부분에 위치한 와류방지톱니(500)에 의해 오히려 유동의 압력 변동이 증가하는 문제를 방지하기 위해, 일부 영역에만 와류방지톱니(500)가 형성되도록 함으로써, 송풍부(100)의 내주면을 따라 전체적으로 와류방지톱니(500)가 형성되었을 때보다 소음 저감 효과가 증대될 수 있다.That is, the shroud 160 reduces noise by suppressing eddy currents and backflow during air blowing due to the rotation of the fan through the vortex preventing tooth 500, but outside the bell mouth 200 and the shroud 160. In order to prevent the problem that the pressure fluctuation of the flow is increased by the vortex preventing tooth 500 located at a portion where the space between the edges is narrowed, the vortex preventing tooth 500 is formed only in a part of the air blowing part 100. Noise reduction effect may be increased than when the vortex preventing teeth 500 are formed along the inner circumferential surface thereof.
아울러, 본 발명의 팬쉬라우드 조립체는 쉬라우드의 중력방향으로 최하단부에 위치한 벨마우스의 와류방지톱니 사이에 형성된 오목한 부분에 쉽게 수분이 고여 동결되는 것을 방지할 수 있다.In addition, the fan shroud assembly of the present invention can easily prevent freezing of moisture accumulated in the concave portion formed between the vortex preventing teeth of the bell mouse located at the lowermost part in the direction of gravity of the shroud.
즉, 본 발명은 쉬라우드의 중력방향으로 최하단부에 와류방지톱니가 형성되지 않는 제2영역이 형성되도록 함으로서, 수분이 고이는 것을 방지하여 동결로 인한 고착 및 결빙을 방지할 수 있는 추가적인 효과를 갖는다.That is, the present invention has the additional effect that the second region in which the vortex preventing teeth are not formed at the lowermost end in the gravity direction of the shroud is prevented from accumulation of moisture, thereby preventing freezing and freezing due to freezing.
본 발명은 상기한 실시예에 한정되지 아니하며, 적용범위가 다양함은 물론이고, 청구범위에서 청구하는 본 발명의 요지를 벗어남이 없이 당해 본 발명이 속하는 분야에서 통상의 지식을 가진 자라면 누구든지 다양한 변형 실시가 가능한 것은 물론이다.The present invention is not limited to the above-described embodiments, and the scope of application of the present invention is not limited to those of ordinary skill in the art to which the present invention pertains without departing from the gist of the present invention as claimed in the claims. Of course, various modifications can be made.
