본 발명은 냉각탑용 냉각팬 구동장치 및 냉각탑에 관한 것으로, 보다 상세하게는 대향류식 냉각탑에서 냉각수의 흐름을 이용하여 냉각팬의 회전력을 발생시키는 냉각탑용 냉각팬 구동장치 및 냉각탑에 관한 것이다.The present invention relates to a cooling fan driving device and a cooling tower for a cooling tower, and more particularly, to a cooling fan driving device and a cooling tower for a cooling tower that generates rotational force of a cooling fan by using a flow of cooling water in a counterflow cooling tower.

일반적으로 냉각탑이란 중앙 집중식 냉방시스템의 실내기, 즉 실내 에어컨에서 냉방에 사용되고 고온화된 냉각수의 온도를 낮추는 장치로서, 크게 냉각수와 외기가 접촉할 때 발생하는 열전달에 의해 냉각수의 온도를 낮추는 개방형과 폐회로 상의 냉각수에 뿌려지는 증발수의 증발잠열을 이용해 냉각수의 온도를 낮추는 폐쇄형 두 가지가 있다.In general, a cooling tower is an indoor unit of a centralized cooling system, that is, a device used for cooling in an indoor air conditioner and lowering the temperature of a high-temperature cooling water. There are two types of closed types that lower the temperature of the cooling water by using the latent heat of evaporation of the evaporation water sprayed on the cooling water.

이 중에서 개방형 냉각탑은 다시 대향류식(Counter Flow Type) 냉각탑, 직교류식(Cross Flow Type) 냉각탑, 무동력 냉각탑 등으로 나누어지며, 특히 대향류식 냉각탑은 측벽 하단에 개방된 흡입구를 통해 유입되어 충전재를 상향 통과하는 외부 공기와 충전재 위쪽에 배치된 분사노즐에서 분사되어 중력에 의해 충전재를 통해 낙하하는 냉각수를 서로 대향시킴으로써 상대적으로 저온인 외기와 상대적으로 고온인 냉각수의 접촉 시 발생하는 열전달에 의해 냉각수를 냉가시키는 원리를 이용하는 것이다.Among them, open cooling towers are divided into counter flow type cooling towers, cross flow type cooling towers, and non-powered cooling towers.In particular, counter flow type cooling towers are introduced through an open inlet at the bottom of the side wall and filled. The cooling water generated by heat transfer generated when the relatively low temperature outside air and the relatively high temperature cooling water contact each other by opposing the external air passing upward through the air and the cooling water falling through the filler by gravity and sprayed from the spray nozzle disposed above the filler material. It is to use the principle of cooling down.

대향류식 냉각탑에서 공기는 수직 상방향으로 유동하고 냉각수는 수직 하방향으로 유동하면서 공기와 냉각수가 접촉하여 열교환이 이루어지고, 직교류식 냉각탑에서 공기는 거의 수평으로 유동하고 냉각수는 수직 하향으로 유동한다.In a counterflow cooling tower, air flows vertically upwards and cooling water flows vertically downwards, and heat exchange occurs by contacting air and cooling water.In a crossflow cooling tower, air flows almost horizontally and cooling water flows vertically downwards. do.

도 1은 조앨의 기술에 의한 대향류식 냉각탑을 도시환 반단면도이며, 도 2는 도 1에서 도시한 대향류식 냉각탑을 도시한 단면도이다. 도 1 및 도 2에 도시한 바와 같이 종래의 기술에 의한 대향류식 냉각탑(1)은 외부 골격을 이루며 외부로부터 공기가 유입되는 흡입구(11)가 측면에 형성되고, 유입된 공기가 외부로 유출되는 토출구(13)가 상부에 형성된 몸체(3)와, 몸체(3) 상부에 설치되어 외부의 공기를 몸체(3) 내부로 유입시켜 외부로 토출되도록 하는 팬(5)과, 공기조화설비(미도시)로부터 분사관(15)으로 순환되는 냉각수를 분사하는 분사노즐(7)과, 분사노즐(7)의 하부로 설치되어 분사된 냉각수를 흡수하는 충전재(9)와, 충전재(9)를 통과하여 낙하하는 물방울이 저장되는 집수조(19)로 이루어지며, 분사노즐(7) 상부로는 토출되는 외기에 의하여 냉각수가 외부로 비산하는 것을 방지하는 엘리미네이터(17)가 설치된다.1 is a half-sectional view showing a counterflow cooling tower according to the technique of Joal, and FIG. 2 is a cross-sectional view showing the counterflow cooling tower shown in FIG. 1. As shown in Figs. 1 and 2, the counterflow type cooling tower 1 according to the prior art forms an external skeleton, and an inlet 11 through which air is introduced from the outside is formed on the side, and the introduced air is discharged to the outside. A body 3 having a discharge port 13 formed at the top, a fan 5 installed on the body 3 to allow external air to flow into the body 3 and discharge to the outside, and an air conditioning facility ( A spray nozzle 7 for spraying coolant circulated from the spray pipe 15 from (not shown), a filler 9 installed under the spray nozzle 7 to absorb the sprayed coolant, and a filler 9 It consists of a water collecting tank 19 in which water droplets falling through it are stored, and an eliminator 17 is installed above the spray nozzle 7 to prevent the cooling water from scattering to the outside by the discharged outside air.

몸체(3)는 원통형 또는 직육면체형의 케이스로서 측면 하단에 외기가 내부로 흡입되는 흡입구(11)가 형성되어 있고, 흡입된 외기가 외부로 토출되는 외기 토출구(13)가 상부에 형성되어 있다.The body 3 is a cylindrical or rectangular parallelepiped case with a suction port 11 through which outside air is sucked into the lower side of the side, and an outside air discharge port 13 through which the sucked outside air is discharged to the outside is formed at the top.

팬(5)은 몸체(3) 상단의 토출구(13)에 설치되어 흡입구(11)를 통해 화살표 방향으로 외기를 흡인하여 토출구(13)를 통해 외부로 배출시키는 역할을 한다. 분사노즐(7)은 충전재(9)와 엘리미네이터(17) 사이에 배치된 분사관(15)에 복수 개가 설치되어 중앙냉방 시스템의 실내 에어컨(10)에서 분사관(15)을 통해 유입되는 냉각수를 충전재(9) 위에 분사하도록 되어 있다. 여기에서 엘리미네이터(17)는 일종의 메시 필터로 충전재에서 떨어져 나온 분진이나 입자가 큰 수포를 잡아 걸러 주는 역할을 한다. 그리고 충전재(9)는 분사노즐(7)과 외기 흡입구(11) 사이에 배치되어 분사노즐(7)에서 분사된 냉각수를 분산시켜 낙하를 방해하거나 수직 필름면에 접하여 수막을 넓게 형성하도록 함으로써 외기와의 접촉면을 최대로 늘려 고온의 냉각수가 용이하게 열을 방출할 수 있도록 해준다.The fan 5 is installed in the discharge port 13 at the top of the body 3 and serves to suck outside air in the direction of the arrow through the suction port 11 and discharge it to the outside through the discharge port 13. A plurality of injection nozzles 7 are installed in the injection pipe 15 disposed between the filler 9 and the eliminator 17 to flow through the injection pipe 15 from the indoor air conditioner 10 of the central cooling system. The cooling water is to be sprayed onto the filler material 9. Here, the eliminator 17 is a type of mesh filter that catches and filters large blisters of dust or particles that have fallen from the filler material. In addition, the filler 9 is disposed between the spray nozzle 7 and the outside air inlet 11 to disperse the coolant sprayed from the spray nozzle 7 to prevent falling or to form a wide water film in contact with the vertical film surface. The maximum contact surface of the hot water coolant allows the heat to dissipate easily.

팬(5)이 작동하면 흡입구(11)를 통하여 외부 공기가 유입되고, 상승하면서 충전재(9)를 통과하고 토출구(13)를 통하여 외부로 토출된다. 그리고 고온 상태의 냉각수는 분사관(15)을 통하여 유입되어 분사관(15)에 구비되는 하나 이상의 분사노즐(7)을 통하여 분사되어 공기와 접촉하여 냉각하면서 충전재(19)를 통과하고 자유 낙하하여 집수조(19)로 집수된다.When the fan 5 is operated, outside air is introduced through the inlet 11, passes through the filler 9 while rising, and is discharged to the outside through the discharge port 13. In addition, the coolant in a high temperature state is introduced through the injection pipe 15 and injected through one or more injection nozzles 7 provided in the injection pipe 15, in contact with air, and cooling while passing through the filler 19 and freely falling. It is collected by the water collecting tank 19.

대향류식 냉각탑에서 공기와 냉각수의 유동방향은 반대로서 서로 접촉하면서 열교환이 이루어져 냉각수가 냉각되며, 공기가 원활하게 흡입되어 충전재를 통과하도록 하기 위하여 집수조(19)와 충전재(9) 사이에는 공간부(18)를 마련한다. 즉 충전재(9)는 집수조(19)로부터 이격되어 집수조(19) 상부에 설치된다.In the counterflow cooling tower, the flow direction of the air and the cooling water are opposite to each other, and heat exchange is performed to cool the cooling water, and the space between the water collecting tank 19 and the filler 9 in order to smoothly suck the air and pass the filler material. Provides (18). That is, the filler 9 is spaced apart from the water collecting tank 19 and installed on the upper part of the water collecting tank 19.

그러나 전술한 일반적인 냉각탑의 경우 팬(5)의 회전을 위하여 모터와 같은 별도의 구동장치가 필요하므로 냉각탑의 전체 설치 비용이 증가하게 되고, 이러한 구동장치는 전기 등을 소비하게 되므로 냉각탑의 유지비용이 증가하게 되는 문제점이 있다.However, in the case of the above-described general cooling tower, since a separate driving device such as a motor is required to rotate the fan 5, the total installation cost of the cooling tower increases, and since such a driving device consumes electricity, the maintenance cost of the cooling tower is reduced. There is a problem that increases.

이러한 문제점을 해결하기 위해서 도 3에 도시된 바와 같이 모터와 같은 별도의 구동장치 없이 냉각수의 흐름을 이용하는 팬구동방식의 냉각탑이 개발되었다.In order to solve this problem, as shown in FIG. 3, a fan-driven cooling tower using the flow of cooling water without a separate driving device such as a motor has been developed.

그러나 냉각수의 흐름을 이용하는 팬구동방식의 냉각탑의 경우 냉각수의 흐름을 팬의 구동을 위한 회전력으로 변환하기 위한 구조가 복잡하고 동력 효율이 떨어지는 문제점이 있다.However, in the case of a fan-driven cooling tower using the flow of cooling water, there is a problem in that the structure for converting the flow of cooling water into rotational force for driving the fan is complicated and power efficiency is inferior.

And an impeller 440 is installed inside the vertical pipe 421. The connection pipe 422 connects the vertical pipe 421 and the cooling tower body 100.

연결부재(430)는 유입관(410)과 분기관(420)을 연결하고, 임펠러(440)를 회전가능하게 지지한다. 그리고 도 7(a)에 도시된 바와 같이, 연결부재(430)에는 유입관(410)에서 분기관(420)으로 흐르는 냉각수에 회전류(vortex)를 형성하기 위한 복수의 볼텍스홀(431)이 형성된다. 본 발명의 실시예에서 연결부재(430)에는 세 개의 볼텍스홀(431)이 형성된다. 볼텍스홀(431)을 통과하는 냉각수는 볼텍스홀(431)의 형상에 의해 그 흐름이 방향성을 갖고 휘어지게 된다. 즉 볼텍스홀(431)의 일측 벽면은 경사면으로 형성되어 경사면에 의해 유도되는 냉각수의 흐름에 의해 회전류가 형성된다. 도 7(b)는 볼텍스홀(431)의 구조를 보여주기 위하여 연결부재(430)의 일부분을 절단하여 나타낸 단면도이다.The connecting member 430 connects the inlet pipe 410 and the branch pipe 420 and rotatably supports the impeller 440. And, as shown in Figure 7 (a), the connecting member 430 has a plurality of vortex holes 431 for forming a vortex in the cooling water flowing from the inlet pipe 410 to the branch pipe 420 Is formed. In the embodiment of the present invention, three vortex holes 431 are formed in the connection member 430. The cooling water passing through the vortex hole 431 is bent with a directional flow due to the shape of the vortex hole 431. That is, one wall surface of the vortex hole 431 is formed as an inclined surface, and a rotational flow is formed by the flow of cooling water guided by the inclined surface. 7(b) is a cross-sectional view showing a part of the connecting member 430 cut away to show the structure of the vortex hole 431.

임펠러(440)는 분기관(420) 내부에 설치되어 분기관(420)으로 유입되는 냉각수에 의해 회전한다. 구체적으로 임펠러(440)는 수직관(421) 내부에 회전가능하게 설치되는 회전축(441)과 회전축(441)에 형성되는 복수의 회전날개(442)로 이루어진다.The impeller 440 is installed inside the branch pipe 420 and rotates by the coolant flowing into the branch pipe 420. Specifically, the impeller 440 includes a rotation shaft 441 rotatably installed inside the vertical pipe 421 and a plurality of rotation blades 442 formed on the rotation shaft 441.

전술한 유입관(410), 수직관(421), 회전축(441)은 일직선을 이루도록 위치함으로써 냉각수의 유입부터 유입된 냉각수가 임펠러(440)를 회전시키기까지 냉각수의 흐름이 꺾이지 않고 수직낙하함으로써 저항을 최소화하여 임펠러(440)를 회전시키기 위한 냉각수의 수력을 극대화시킬 수 있다. 또한, 볼텍스홀(431)을 통과하는 냉각수에 회전류를 형성함으로써 냉각수의 흐름 속도를 증가시키고 냉각수에 의해 회전날개(442)에 작용하는 항력을 높일 수 있다.The above-described inlet pipe 410, vertical pipe 421, and rotation shaft 441 are positioned so as to form a straight line, so that the flow of cooling water from the inflow of the cooling water to the rotation of the impeller 440 is vertically dropped without breaking resistance. By minimizing, it is possible to maximize the hydraulic power of the cooling water for rotating the impeller 440. In addition, by forming a rotational flow in the cooling water passing through the vortex hole 431, it is possible to increase the flow rate of the cooling water and increase the drag acting on the rotating blades 442 by the cooling water.

냉각팬(500)은 임펠러(440)와 연결되어 회전한다. 즉 냉각팬(500)은 회전축(441)과 연결되어 회전하게 된다. 상술한 바와 같이 별도의 구동모터 없이 단순화된 구조로 유입되는 냉각수를 이용하여 냉각팬(500)을 회전시킴으로써 냉각팬(500)을 회전시키기 위한 동력 및 동력 효율을 극대화시킬 수 있다.The cooling fan 500 is connected to the impeller 440 and rotates. That is, the cooling fan 500 is connected to the rotation shaft 441 and rotates. As described above, power and power efficiency for rotating the cooling fan 500 can be maximized by rotating the cooling fan 500 using the cooling water introduced in a simplified structure without a separate driving motor.

본 발명에 따른 냉각탑용 냉각팬 구동장치는 전술한 실시예에 국한되지 않고 본 발명의 기술사상이 허용되는 범위 내에서 다양하게 변형하여 실시할 수 있다.The cooling fan driving apparatus for a cooling tower according to the present invention is not limited to the above-described embodiments, and can be implemented with various modifications within the scope of the technical idea of the present invention.
