본 고안은 회전기기용 냉각팬에 관한 것으로 특히 냉각팬의 날개를 개량하여 풍량을 증가시킴에 따라 냉각효율을 향상시킨 회전기기용 냉각팬에 관한 것이다.The present invention relates to a cooling fan for a rotary machine, and more particularly to a cooling fan for a rotary machine to improve the cooling efficiency by increasing the air volume by improving the blade of the cooling fan.
일반적으로 회전기기인 교류발전기는 엔진의 동력에 따라 내부의 회전자가 회전하면서 전압을 유기하게 되는 것으로 그 구조는 제1도에 도시된 바와 같이 전후후레임(1)내에 고정자(2)가 고정되고 고정자(2) 안쪽에 계자철심(5)과 계자코일(6), 자극호(7)로 이루는 회전자(3)가 회전자축(4)에 고정되어 회전하면서 전압을 유기하게 되는데, 이때 전후후레임(1)에는 흡기홀(8)과 배기홀(9)이 형성되어 있고, 회전자(3)의 양측에는 원심날개(11)를 갖는 냉각팬(11)이 부착설치되어 회전시 냉각팬(10)의 원심 날개(11)에 의해 공기를 강제 순환시키며 발전기를 냉각시키게 되어 있다.In general, the alternator, which is a rotating device, induces a voltage while the internal rotor rotates according to the power of the engine. The structure of the alternator is fixed in the front and rear frames 1 as shown in FIG. (2) The rotor (3) consisting of the field iron core (5), the field coil (6), the magnetic pole arc (7) is fixed to the rotor shaft (4) inside to rotate and induce voltage, and at this time the front and rear frame ( 1) an intake hole 8 and an exhaust hole 9 are formed, and on both sides of the rotor 3, a cooling fan 11 having a centrifugal blade 11 is attached to the cooling fan 10 during rotation. The air is forcedly circulated by the centrifugal blade 11 to cool the generator.
이와 같은 종래의 냉각팬(10)은 평판의 원심날개(11)가 냉각팬(10)으로부터 수직으로만 제2도에 도시된 바와 같이 적립되어 있어서 전기자코일과 같은 발열체에 대한 효과적인 냉각에 한계가 있었다.Such a conventional cooling fan 10 is a centrifugal blade 11 of the flat plate is accumulated vertically from the cooling fan 10 only as shown in Figure 2 has a limit to the effective cooling for heating elements such as armature coils there was.
본 고안은 이와 같은 점을 감안하여 안출한 것으로 냉각팬의 원심날개를 원호형상이 되게 함으로써 송풍효율을 향상시킬 수 있도록 한 것이다.The present invention has been devised in view of such a point to improve the blowing efficiency by making the centrifugal blades of the cooling fan arcuate.
이를 첨부도면에 의거하여 상세히 설명하면 다음과 같다.When described in detail based on the accompanying drawings as follows.
본 고안은 원심형 날개를 갖는 회전기기용 냉각팬에 있어서, 날개(20)를 냉각팬(10)으로부터 수직으로 세우되 날개(10)의 단면이 원호형상을 갖게 한 구조이다.The present invention is a cooling fan for a rotary machine having a centrifugal blade, the blade 20 is perpendicular to the cooling fan 10, the cross section of the blade 10 has a circular arc shape.
여기서 날개(20)는 기존의 날개와 동일 높이가 되게 하는 동시에 제3도(가)에서와 같이 선단과 접면 사이의 중간부분이 내곡된 형상을 하게 되며, 본 고안의 또 다른 실시예로는 제3도(나)에서와 같이 선단부분만이 절곡된 형상을 하게 된다.Here, the wing 20 is to be the same height as the existing wing and at the same time as the third part (a) is to have a curved shape of the middle portion between the tip and the contact surface, as another embodiment of the present invention As shown in Fig. 3 (b), only the tip portion has a bent shape.
이와 같이 구성된 본 고안은 제1도에 도시된 바와 같이 회전기기인 발전기의 후레임(1)에 흡기홀(8)과 배기홀(9)이 형성되고 회전체인 회전자(3) 양측에 냉각팬(10)이 부착설치되어서 회전시 회전자(30의 양측 냉각팬(10)에의해 냉각공기가 후레임(1)의 흡기홀(8)을 통해 유입되어 내부의 고정자코일 등을 냉각한 후 배기홀(9)을 통해 강제 배출하게 된다.According to the present invention, the intake hole 8 and the exhaust hole 9 are formed in the frame 1 of the generator, which is a rotating device, as shown in FIG. (10) is attached to the cooling air flows through the intake hole (8) of the frame (1) by the cooling fan (10) on both sides of the rotor (30) during rotation to cool the stator coils and the like inside the exhaust hole Forced discharge through (9).
이때 회전자(3) 양측에 부착설치된 냉각팬(10)에는 날개(20)가 제4도와 같이 원심형으로 형성되는 동시에 단면이 원호형상을 갖게 되므로 냉각풍량이 증대되어 냉각공기를 보다 많이 유입시키게 되고 배기홀로 배출시키며 냉각효율을 향상시키게 된다.At this time, the cooling fan 10 attached to both sides of the rotor 3 has the wing 20 formed in a centrifugal shape as shown in FIG. It is discharged to the exhaust hole and improves the cooling efficiency.
이와 같은 냉각효율은 제5도에서와 같이 본 고안(b)의 원호상날개(20)를 적용시켰을 때가 종래(a)냉각팬에 의해 냥각된 온도보다 고정자코일의 온도가 대략 10℃정도 저감도였다.Such cooling efficiency is reduced by approximately 10 ° C. when the arcuate blade 20 of the present invention (b) is applied as in FIG. It was.
이상에서와 같이 본 고안은 냉각팬의 날개를 원호형상으로 구성시킴으소써 발전기 내측으로 유입되는 냉각공기의 풍량이 증가되어 전기자코일과 정류기 등의 온도를 효과적으로 냉각시킬 수 있으므로 내열성능을 향상시킬 수 있는 효과가 있다.As described above, the present invention has a circular arc shape of the cooling fan so that the air volume of the cooling air flowing into the generator can be increased to effectively cool the temperature of the electric coil and the rectifier, thereby improving heat resistance. It works.
