Description
본 발명은 터보 블로워장치에 관한 것으로, 특히 구동부와 제어부가 서로 연통되도록 형성되어 하나의 냉각 통로에 의해 냉각이 동시에 이루어지도록 함으로써 냉각 효율을 극대화하고, 유동손실을 저감하기 위해 임펠러 앞단과 분리벽 사이의 거리를 최대한 멀리하기 위해 구동부를 대각선으로 배치하는 터보 블로워장치에 관한 것이다.The present invention relates to a turbo blower, and in particular, the drive unit and the control unit is formed so as to communicate with each other to achieve the cooling by one cooling passage at the same time to maximize the cooling efficiency, and to reduce the flow loss between the impeller front and the separation wall It relates to a turbo blower for arranging the drive diagonally to maximize the distance of the distance.
일반적으로, 송풍기(Blower)는 유체의 에너지를 발생시키는 기계장치를 말하는 것으로, 송풍기는 유동을 일으키는 임펠러(impeller), 임펠러로 들어가고 나오는 유동을 안내하는 케이싱(casing)으로 이루어진다.Generally, a blower refers to a mechanism for generating energy of a fluid, and the blower is composed of an impeller causing a flow and a casing for guiding the flow into and out of the impeller.
이러한, 송풍기의 분류 방법에는 여러 가지가 있는데 가장 일반적인 방법은 날개차를 통과하는 유동의 특성에 의한 분류이며, 그것은 축류형 송풍기(Axial Blower), 반경류형 송풍기(Radial Blower), 혼합류형 송풍기(Mixed Blower)로 나눈다.There are a number of methods for classifying blowers, the most common method being classification by the characteristics of the flow through the vanes, which is called Axial Blower, Radial Blower, and Mixed Flow Blower. Blower).
공기의 유동이 날개차의 회전축과 평행 방향으로 발생하면 축류송풍기라고 하며, 이 경우에는 임펠러 입구와 출구의 유동방향이 모두 회전축과 일치한다. 프로펠러형 송풍기, 즉 보통의 가정용 선풍기가 여기에 속한다. When the flow of air occurs in the direction parallel to the rotor shaft, it is called an axial blower. In this case, the flow direction of the impeller inlet and outlet coincides with the rotor shaft. Propeller blowers, ie ordinary household fans, belong here.
축류형 송풍기는 가해준 에너지가 주로 유체의 속도를 증가시키는 데 사용되며, 따라서 유량은 많이 필요하나 압력은 그리 필요하지 않은 곳에 사용된다.Axial blowers are used where the energy applied is primarily used to increase the velocity of the fluid, so that a lot of flow is required but not so much pressure.
반경류형 송풍기는 원심력에 의한 압력 증가가 주된 목적이며 따라서 유량보다는 압력이 필요한 곳에 많이 사용된다.The radial blower is mainly designed to increase the pressure by centrifugal force and is therefore used where pressure is needed rather than flow rate.
또한, 상기 원심형 송풍기는 보통 임펠러 입구 유동은 회전축 방향이나 출구 유동은 회전축의 직각 방향이 되도록 나선형의 케이싱을 사용하는 경우와, 임펠러 입구 유동과 출구 유동이 둘 다 회전축 방향이 되도록 튜브형 케이싱을 사용하는 경우로 크게 구별된다.In addition, the centrifugal blower generally uses a spiral casing such that the impeller inlet flow is in the direction of the rotational axis but the outlet flow is in the direction perpendicular to the axis of rotation, and the tubular casing is used so that both the impeller inlet flow and the outlet flow are in the direction of the axis of rotation. This is largely distinguished.
아울러, 상기 혼합류형 송풍기는 임펠러 내에서 축 방향과 반경 방향의 유동이 같이 존재하는 경우로 유량과 압력의 증가가 동시에 요구될 때 사용된다. In addition, the mixed flow blower is used when an increase in flow rate and pressure is required in the case where axial and radial flows exist together in the impeller.
이외에 임펠러의 회전에 의하지 않는 새로운 방식의 송풍기들이 특수 목적에 사용되기도 하는데, 압전 소자를 이용하여 모터가 필요없는 송풍기가 사용되기도 한다. 송풍기는 그 응용 대상과 작동 특성에 따라 적절히 선택되어야 하는데, 공업적으로는 공기조화시스템, 각종 흡,배기시스템 등에 주로 사용된다. 그 크기도 컴퓨터용 냉각팬 등 소형으로부터 대형 공업용 송풍기에 이르기까지 다양하다.In addition, new types of blowers that do not depend on the rotation of the impeller may be used for special purposes, and some may use a piezoelectric element without a motor. The blower should be appropriately selected according to its application and operating characteristics. Industrially, it is mainly used for air conditioning system, various intake and exhaust systems. The size also varies from small to large industrial blowers such as computer cooling fans.
이러한, 원심 송풍기의 일종인 터보블로워(Turbo Blower)는 비교적 압력비가 큰 원심 송풍기를 말하는 것으로, 임펠러(impeller)를 용기 속에서 고속 회전시켜 기체를 방사상으로 흐르게 하고, 원심력을 이용하는 원심송풍기중에서 압력비가 작은 것을 원심형 통풍기, 터보통풍기라 하고, 압력비가 그 이상의 것을 원심형 송풍기, 터보송풍기라고 한다.The turbo blower, which is a kind of centrifugal blower, refers to a centrifugal blower having a relatively high pressure ratio, and the pressure ratio is increased in a centrifugal blower using a centrifugal force by rotating an impeller at a high speed in a container. The smaller ones are called centrifugal ventilators and turbo blowers, while the pressure ratios are higher than the centrifugal blowers and turbo blowers.
상기와 같은, 종래기술의 터보 블로워는 도 1 및 도 2에서와 같이, 본체(10)의 내부 일측에 배치되며 외기를 흡입하여 송풍하기 위한 구동부(20)와, 본체(10)의 내부 타측에 구동부(20)와 분리벽(15)으로 구획된 제어부(50)가 배치된다.As described above, the turbo blower of the prior art is disposed on one side of the main body 10, as shown in Figs. 1 and 2, and the drive unit 20 for sucking and blowing outside air and the other side of the main body 10. The controller 50 divided into the driving unit 20 and the separating wall 15 is disposed.
구동부(20)의 상측에는 구동부의 임펠러를 통해 가압된 공기를 외부로 송풍시키기 위한 토출구(30)이 구비되어 있다.The upper side of the drive unit 20 is provided with a discharge port 30 for blowing air pressurized through the impeller of the drive unit to the outside.
본체(10)는 일측 하부에 외기가 내부로 유입되는 유입구(12)가 형성되고, 유입구(12)를 통해 내부로 유입된 공기가 구동부(20)를 거쳐서 본체(10)의 상부에 배치된 흡입팬(40)을 통과하게 되어 구동부(20)의 냉각이 이루어지게 된다.The main body 10 has an inlet 12 through which the outside air is introduced into the lower portion of one side, and the air introduced into the inside through the inlet 12 is disposed on the upper portion of the main body 10 via the driving unit 20. Passing through the fan 40 is the cooling of the drive unit 20 is made.
또한, 제어부(50)는 구동부(20)와는 별개로 밀폐 구획된 타측 내부에 배치된 캐비넷 구조로 되어 있으므로, 구동부(20)와는 별개의 냉각 과정을 갖는다.In addition, since the control unit 50 has a cabinet structure disposed inside the other side of the drive unit 20 separately sealed, the control unit 50 has a separate cooling process from the drive unit 20.
미설명부호 "55"는 인버터를 나타낸 것이다.Reference numeral "55" indicates an inverter.
제어부(50)의 냉각을 위해서는 본체(10)의 타측 상부와 하부에 통기공(14,16)이 각각 형성되어 공기의 유입 및 유출을 통해 자연 냉각되도록 된 것이다.In order to cool the control unit 50, vent holes 14 and 16 are formed at the upper and lower sides of the main body 10, respectively, to naturally cool the air through inflow and outflow of air.
이로 인해, 기존의 터보 블로워장치는 구동부(20)와 제어부(50)의 냉각을 위해 개별적인 냉각 구조가 요구되는 번거로움이 있다.For this reason, the conventional turbo blower has a hassle that requires a separate cooling structure for cooling the drive unit 20 and the control unit 50.
또한, 구동부 내에 배치된 로터 및 로터의 냉각을 위한 장치가 없으므로 쉽게 과열 및 열화될 우려가 있으며, 이로 인해 부품의 성능이 저하되는 단점이 있다.In addition, since there is no device for cooling the rotor and the rotor disposed in the driving unit, there is a concern that it may be easily overheated and deteriorated, and thus there is a disadvantage in that the performance of the component is degraded.
본 발명은 상기한 제반 문제점을 감안하여 이를 해결하고자 창출된 것으로, 그 목적은 터보 블로워의 구동부와 제어부가 하나의 냉각 통로를 통해 자연 냉각이 가능하도록 함과 아울러, 구동부 내의 각 구성요소들을 개별적으로 냉각시켜 제품의 성능 저하를 방지하고 부품 신뢰성을 향상시킬 수 있도록 그 구조가 개선된 터보 블로워장치를 제공하는 데 있다.The present invention has been made in view of the above-mentioned problems, and an object thereof is to provide a natural cooling through one cooling passage and a drive unit and a control unit of a turbo blower, and to individually control each component in the drive unit. The present invention provides a turbo blower having an improved structure so that cooling can prevent product degradation and improve component reliability.

It is.
더 상세히 설명하면, 분리벽(120)은 통공(125)이 형성되어 구동부(200)가 배치된 본체(100)의 내부 일측과 제어부(500)가 배치된 본체(100)의 내부 타측이 서로 연통되도록 형성된 것이다.In more detail, the separation wall 120 has a through hole 125 formed therein, and an inner side of the main body 100 in which the driving unit 200 is disposed and an inner side of the main body 100 in which the control unit 500 is disposed communicate with each other.

제 1쿨링유로(216)는 외측 하우징(210)의 하부에 천공되도록 형성되어 내측 하우징(230)의 내부와 연통되도록 형성되므로, 외기를 로터(240) 및 스테이터(245)의 사이 틈새로 유도함으로써, 외기가 외측 하우징(210)과 내측 하우징(230)의 내부를 통과하여 커버(220) 측으로 배출되도록 된 것이다.Since the first cooling passage 216 is formed to be perforated in the lower portion of the outer housing 210 to communicate with the inside of the inner housing 230, by inducing the outside air into the gap between the rotor 240 and the stator 245. The outside air passes through the inside of the outer housing 210 and the inner housing 230 to be discharged toward the cover 220.
이를 위해 로터(240)과 스테이터(245) 사이에 외기가 통과될 수 있도록 틈새 또는 홈 형태의 공기 통로가 형성되는 것이 바람직하다.To this end, it is preferable that an air passage in the form of a gap or groove is formed between the rotor 240 and the stator 245 so that outside air can pass therethrough.
또한, 외측 하우징(210)은 상기 회전축(250) 내부로 외기를 유도하기 위한 제 2쿨링유로(218)가 형성된다.In addition, the outer housing 210 is formed with a second cooling flow path 218 for inducing outside air into the rotating shaft 250.
제 2쿨링유로(218)는 외측 하우징(210)의 하부에 천공되도록 형성되고, 외기가 회전축(250)의 단부를 통해 회전축(250)의 내부로 유입되도록 형성된 것이다.The second cooling passage 218 is formed to be perforated in the lower portion of the outer housing 210, and the outside air is formed to flow into the inside of the rotating shaft 250 through the end of the rotating shaft 250.

이러한 구성을 갖는 본 발명의 작용은 다음과 같다. The operation of the present invention having such a configuration is as follows.
본 발명에 의한 터보 블로워장치는, 구동부(200)와 제어부(500)가 유로(105)를 통해 서로 연통되도록 배치되어 있으므로, 유입구(110)를 통해 유입되는 외기에 의해 자연 냉각이 이루어지게 된다.In the turbo blower according to the present invention, since the driving unit 200 and the control unit 500 are arranged to communicate with each other through the flow path 105, natural cooling is performed by the outside air introduced through the inlet 110.
이때, 외기의 흐름과정은 본체(100)의 일측 하부에 천공된 유입구(110)를 통해 외기가 유입되고, 격벽(130)에 의해 분기된 상태로 분리벽(120)의 통공(125)을 통해 제어부(500)가 배치된 본체(100)의 타측 내부로 유입됨과 아울러, 구동부(200)의 유입공(212)을 통해 외측 하우징(210)의 내부로 유입된다.At this time, the flow of the outside air is introduced into the outside air through the inlet 110 perforated in one lower portion of the main body 100, through the through hole 125 of the separation wall 120 in a state branched by the partition wall 130 The control unit 500 is introduced into the other side of the main body 100 in which the control unit 500 is disposed, and also flows into the outer housing 210 through the inlet hole 212 of the driving unit 200.
본체(100)의 타측 내부로 유입된 외기는 제어부(500)와 인버터(550)를 냉각시킨 후에, 본체(100)의 타측 상부에 형성된 통기공(140)을 통해 외부로 배출되는 흐름과정을 가지며, 이 과정에서 제어부(500)와 인버터(550)의 냉각이 이루어지게 된다.The outside air introduced into the other side of the main body 100 has a flow process discharged to the outside through the air vent 140 formed on the other side of the main body 100 after cooling the control unit 500 and the inverter 550 In this process, the controller 500 and the inverter 550 are cooled.
외측 하우징(210)의 내부로 유입된 외기는 배출공(214)을 통해 외부로 배출된다.Outside air introduced into the outer housing 210 is discharged to the outside through the discharge hole 214.
또한, 구동부(200)는 임펠러(260) 구동시 흡입구(202)를 통해 유입된 공기가 임펠러(260)에 의해 가압되어 케이싱(270)을 통해 토출구(300)측으로 송풍되는 것은 기존 방식과 동일하므로, 자세한 설명은 생략하기로 한다.In addition, the driving unit 200 is the air flowing through the inlet 202 when the impeller 260 is driven by the impeller 260 is blown through the casing 270 to the discharge port 300 side is the same as the conventional method , Detailed description thereof will be omitted.

제 1쿨링유로(216)는 내측 하우징(230)의 내부와 연통되도록 외측 하우징(210)의 하부에 천공 형성되어 있으므로, 외기가 내측 하우징(230)의 내부를 통과하여 커버(220)를 통해 외부로 배출되는 과정중에 내측 하우징(230)의 내측에 배치된 스테이터(245)와 로터(240) 사이를 통과하면서 스테이터(245)와 로터(240)를 냉각시키는 기능을 수행하게 된다.Since the first cooling passage 216 is formed in the lower portion of the outer housing 210 so as to communicate with the inside of the inner housing 230, the outside air passes through the inside of the inner housing 230 and is externally opened through the cover 220. During the discharge process, the stator 245 and the rotor 240 are cooled while passing between the stator 245 and the rotor 240 disposed inside the inner housing 230.
제 2쿨링유로(218)는 회전축(250)의 내부와 연통되도록 외측 하우징(210)의 하부에 천공 형성되어 있으므로, 외기가 회전축(250)의 내부를 통과하여 커버(220)를 통해 외부로 배출되면서 회전축(250)을 냉각시키는 기능을 수행하게 된다.Since the second cooling passage 218 is formed in the lower portion of the outer housing 210 so as to communicate with the inside of the rotation shaft 250, the outside air passes through the inside of the rotation shaft 250 and is discharged to the outside through the cover 220. While performing the function of cooling the rotating shaft 250.
이때, 회전 임펠러(280)는 임펠러(260)의 구동과 연계되어 연동 회전되므로, 제 2쿨링유로(218)를 통해 유입되는 외기를 강제로 회전축(250)의 내부로 유입시켜 회전축(250)의 냉각 효율을 향상시킬 수 있다.At this time, since the rotary impeller 280 is interlocked with the driving of the impeller 260, the external air flowing through the second cooling flow path 218 is forced to enter the inside of the rotary shaft 250 of the rotary shaft 250 Cooling efficiency can be improved.

이는, 제 3쿨링유로(216a)를 통해 내측 하우징(230)의 내부로 유입되는 외기가 커버(220)측으로 배출되면서 로터(240) 및 스테이터(245)을 냉각시킴과 아울러, 제 4쿨링유로(252)를 통해 회전축(250)의 내부로 유입된 후에 커버(220)측으로 배출되면서 회전축(250)을 냉각시키는 기능을 수행하도록 된 것이다.This cools the rotor 240 and the stator 245 while the outside air flowing into the inside of the inner housing 230 through the third cooling passage 216a is discharged to the cover 220 side, and the fourth cooling passage ( After entering the inside of the rotating shaft 250 through the 252 is discharged to the cover 220 side to perform the function of cooling the rotating shaft 250.
따라서, 본 발명은 구동부(200)와 제어부(500)가 서로 연통된 하나의 공기 유로를 통해 유입되는 외기에 의해 자연 냉각됨과 아울러, 구동부(200)를 구성하는 각 구성요소들에 대한 개별 냉각이 가능하게 됨에 따라 과열을 예방하여 부품 수명을 연장시킬 수 있다.Therefore, the present invention is naturally cooled by the outside air introduced through the one air flow path in which the driving unit 200 and the control unit 500 communicate with each other, and the individual cooling for each component constituting the driving unit 200 When possible, overheating can be prevented to extend component life.
