Description

냉각팬 구동모터의 열해방지장치{Cooling apparatus for drive motor in cooling fan}Cooling apparatus for drive motor in cooling fan

본 발명은 냉각팬 구동모터의 열해방지장치에 관한 것으로, 보다 상세하게는 냉각팬의 날개 전방에 팬이 회전하면서 유입된 공기를 리브쪽으로 유도하도록 하는 별도의 공기유도부재를 형성하여 구동모터를 냉각하도록 하는 냉각팬 구동모터의 열해방지장치에 관한 것이다.The present invention relates to a thermal damage prevention apparatus of a cooling fan drive motor, and more particularly, to form a separate air induction member to guide the introduced air toward the rib while the fan rotates in front of the wing of the cooling fan to cool the drive motor. The present invention relates to a device for preventing thermal degradation of a cooling fan drive motor.

일반적으로 내연기관을 장착하고 있는 차량에서는, 엔진이 가동함에 따라 연소가스에서 발생하는 열이 실린더 헤드와 피스톤, 밸브 등으로 전도되게 되고, 이러한 부품들의 온도가 과도하게 높아지게 되면 부품의 재료강도가 저하되게 되어 고장의 원인이 되거나 수명이 단축되게 되며, 연소상태도 나빠져서 노킹이나 조기점화가 발생하게 되어, 그 결과 엔진출력이 저하되게 된다.In general, in a vehicle equipped with an internal combustion engine, the heat generated from the combustion gas is conducted to the cylinder head, the piston, the valve, and the like as the engine operates, and when the temperature of these parts becomes excessively high, the material strength of the parts decreases. This may cause a failure or shorten the lifespan, worsen the combustion state, causing knocking or premature ignition, resulting in lower engine power.

이러한 엔진의 가열을 방지하기 위해 라디에이터는 수냉식 엔진에서 열을 공기중에 방출하기 위한 것으로 냉각팬에 의해 냉각되도록 되어 있다.In order to prevent the engine from being heated, the radiator is for dissipating heat into the air in a water-cooled engine and is cooled by a cooling fan.

상기한 냉각팬을 구동하는 방식은 크게 두가지로 구분되는데, 첫째는 워터펌프의 구동력을 벨트로 전달받아 구동하는 방식과, 별도의 구동모터를 장착하여 모터의 회전력을 이용하여 냉각팬을 회전시키는 구동팬방식이 있다.The method of driving the cooling fan is largely divided into two types. Firstly, the driving force of the water pump is transferred to the belt and driven, and the driving of rotating the cooling fan using the rotational power of the motor by mounting a separate driving motor. There is a fan method.

또한, 상기한 구동팬 방식은 압송형 전동팬과, 흡입형 전동팬으로 구분된다. 압송형 전동팬은 라디에이터의 전방에 형성되어 라디에이터측으로 외기를 불어넣는 방식이며, 흡입형 전동팬은 라디에이터의 후측에 장착되어 외기를 라디에이터 쪽으로 흡입하는 방식이다.In addition, the driving fan method is classified into a pressure type electric fan and a suction type electric fan. The pressure type electric fan is formed in front of the radiator to blow external air to the radiator side, and the suction type electric fan is mounted to the rear side of the radiator to suck external air toward the radiator.

도 4는 종래의 냉각팬의 장착상태를 설명하기 위한 도면으로, 라다에이터 (10)의 후방에는 구동모터(12)에 의해 회전하는 냉각팬(13)이 형성되어 있으며, 냉각팬(13)의 후측의 엔진룸에 엔진(11)이 장착되어 있다. 도 5는 종래의 냉각팬 (13)의 정면도로, 허브(14)의 외주에 방사상으로 날개(15)가 다수 형성되어 있고, 구동모터(12)의 회전축(12a)이 축수부(16)에 축삽되어 있다. 이 축수부(16)는 상기 허브(14)와 방사상으로 형성되는 다수의 리브(17)로써 연결되어 있는데, 이 리브(17)는 구동모터(12)의 열해를 방지하기 위해 형성되는 것이다.4 is a view for explaining a mounting state of a conventional cooling fan, a cooling fan 13 that is rotated by the drive motor 12 is formed at the rear of the ladator 10, the cooling fan 13 of The engine 11 is attached to the rear engine room. 5 is a front view of a conventional cooling fan 13, in which a plurality of blades 15 are radially formed on the outer circumference of the hub 14, and the rotation shaft 12a of the drive motor 12 is connected to the bearing portion 16. As shown in FIG. It is moistened. The bearing 16 is connected to the hub 14 by means of a plurality of ribs radially formed. The ribs 17 are formed to prevent thermal damage of the driving motor 12.

또한, 구동모터의 열해를 방지하기 위해서 구동모터(12)의 케이스 외주에 냉각홀(12b)이 다수 형성되어 있다.In addition, in order to prevent thermal damage of the drive motor, a plurality of cooling holes 12b are formed in the outer periphery of the case of the drive motor 12.

그러나, 상기와 같이 형성되는 리브와 냉각홀 만으로는 구동모터를 충분하게 냉각시키지 못하고 구동모터가 열해를 입게 되어 구동모터의 내구력이 약해지는 문제점이 있었다.However, only the ribs and the cooling holes formed as described above do not sufficiently cool the driving motor, and the driving motor suffers thermal damage, thereby weakening the durability of the driving motor.

따라서 본 발명은 상기한 문제점을 개선하기 위하여 안출된 것으로서, 보다 상세하게는 냉각팬의 날개 전방에 팬이 회전하면서 유입된 공기를 리브쪽으로 유도하도록 하는 별도의 공기유도부재를 형성하여 구동모터를 냉각하도록 하는 냉각팬 구동모터의 열해방지장치를 제공하는 데 목적이 있다.Therefore, the present invention has been made in order to improve the above problems, and more specifically, to form a separate air induction member to guide the introduced air to the rib while the fan rotates in front of the blade of the cooling fan to cool the drive motor It is an object of the present invention to provide a thermal protection device for a cooling fan drive motor.

본 발명은 상기와 같은 목적을 달성하기 위한 수단으로서,The present invention as a means for achieving the above object,

구동모터의 회전축이 축수부에 축삽되고, 축수부는 허브와 리브로써 연결되며, 허브의 외주에 다수의 날개가 형성된 채로 라디에이터의 일측에 장착되어 라디에이터의 냉각효율을 높이는 냉각팬에 있어서,In the cooling fan that the rotating shaft of the drive motor is inserted into the bearing portion, the bearing portion is connected to the hub and the rib, mounted on one side of the radiator with a plurality of wings formed on the outer periphery of the hub, to increase the cooling efficiency of the radiator,

상기한 냉각팬이 회전하면서 날개에 부딪치는 공기가 수용되도록 전방을 향해 개방된 공기입구가 형성되고, 허브의 내측으로 공기입구에서 유입된 공기가 배출되도록 공기출구가 형성되는 유선형의 공기유도부재가 날개의 전방에 부착되는 것을 특징으로 하며,As the cooling fan rotates, an air inlet is formed to be opened toward the front to accommodate the air that hits the wing, and a streamlined air induction member in which the air outlet is formed to discharge the air introduced from the air inlet into the hub is provided.

본 발명의 실시예를 첨부한 도면에 따라 상세히 설명하면 다음과 같다.An embodiment of the present invention will be described in detail with reference to the accompanying drawings.

도 1은 본 발명에 의해 구성된 냉각팬의 장착상태를 설명하기 위한 도면이며, 도 2는 본 발명에 의해 구성된 냉각팬의 정면도이며, 도 3은 본 발명에 의해 구성된 냉각팬 날개의 단면도로서, 도면중 도면부호 20은 냉각팬이다.1 is a view for explaining the mounting state of the cooling fan constructed by the present invention, Figure 2 is a front view of the cooling fan constructed by the present invention, Figure 3 is a cross-sectional view of the cooling fan blades constructed by the present invention, Reference numeral 20 is a cooling fan.

상기한 냉각팬(20)은 구동모터(30)의 회전축(31)이 축수부(21)에 축삽되고, 축수부(21)는 외주에 다수의 날개(22)가 부착된 원형의 허브(23)와 다수의 리브(24)에 의해 일체로 형성된다. 상기 리브(24)들은 방사상으로 형성되며 냉각팬(20)의 중량을 감소하기 위해 얇게 형성하는 것이 바람직하다.The cooling fan 20 has a rotating shaft 31 of the drive motor 30 is inserted into the bearing portion 21, the bearing portion 21 is a circular hub 23 is attached to the outer periphery a plurality of wings (22) ) And a plurality of ribs 24 are formed integrally. The ribs 24 are formed radially and thinly formed to reduce the weight of the cooling fan 20.

상기한 날개(22)의 전방측에는 냉각팬(20)이 회전하면서 날개(22) 전면에 부딪치는 공기를 허브(23) 내주연으로 유도하기 위한 공기유도부재(25)가 부착된다. 이 공기유도부재(25)는 날개(22)의 중간부분에 공기입구(26)가 형성되며, 허브(23)의 내주연으로는 공기출구(27)가 형성된다. 공기출구(27)가 허브(23) 내주연으로 형성되는 이유는 냉각팬(20)이 회전하면서 날개(22)에 부딪치는 일부의 공기를 유도하여 구동모터(30)를 냉각하기 위한 것이다.An air induction member 25 is attached to the front side of the blade 22 to guide the air hitting the front surface of the blade 22 to the inner circumference of the hub 23 while the cooling fan 20 rotates. The air induction member 25 has an air inlet 26 is formed in the middle portion of the blade 22, the air outlet 27 is formed in the inner circumference of the hub (23). The reason why the air outlet 27 is formed in the inner circumference of the hub 23 is to cool the driving motor 30 by inducing some of the air collided with the blades 22 while the cooling fan 20 rotates.

특히, 상기한 공기입구(26)는 냉각팬(20)의 회전방향으로 개방되어냉각팬(20)의 회전시 많은 양의 공기가 유입되도록 형성된다.In particular, the air inlet 26 is opened in the rotational direction of the cooling fan 20 so that a large amount of air is introduced during the rotation of the cooling fan 20.

또한, 상기한 공기유도부재(25)는 냉각팬(20)이 회전하는 경우에 저항을 최대한 감소하기 위해 유선형으로 형성하는 것이 바람직하다. 이 공기유도부재(25)는 냉각팬(20)을 사출하면서 일체로 형성하면 냉각팬의 중량도 가볍고 그 제작 비용도 절감된다.In addition, the air guide member 25 is preferably formed in a streamline to reduce the resistance as much as possible when the cooling fan 20 is rotated. When the air induction member 25 is integrally formed while injecting the cooling fan 20, the weight of the cooling fan is light and the manufacturing cost thereof is reduced.

이상과 같이 구성된 냉각팬(20)은 구동모터(30)에 의해 가동되어 라디에이터의 냉각효율을 향상하도록 라디에이터의 전방 혹은 후방에 설치된다.The cooling fan 20 configured as described above is installed at the front or rear of the radiator to be operated by the drive motor 30 to improve the cooling efficiency of the radiator.

그리고 구동모터(30)의 하우징에는 구동모터(30)의 냉각을 위해 종래와 같이 냉각홀(32)을 형성하는 것이 바람직하다.In addition, it is preferable to form the cooling holes 32 in the housing of the drive motor 30 as in the prior art for cooling the drive motor 30.

이상과 같이 구성된 냉각팬의 작동상태를 설명하면 다음과 같다.Referring to the operating state of the cooling fan configured as described above are as follows.

엔진(50)이 가동되면 엔진을 냉각하기 위해 라디에이터(40)가 작동되고, 이 라디에이터(40)의 효과적인 냉각을 위해 냉각팬(20)을 회동시키기 위한 구동모터(30)가 작동하게 된다.When the engine 50 is operated, the radiator 40 is operated to cool the engine, and the drive motor 30 for rotating the cooling fan 20 is operated for effective cooling of the radiator 40.

이때 냉각팬(20)을 회전시키는 구동모터(30)에도 열이 발생하게 되지만, 냉각팬(20)에 형성된 공기유도부재(25)의 공기입구(26)로 날개(22)에 부딪치는 공기를 흡입하여 공기출구(27)로 유도하여 리브(24) 안쪽으로 강하게 방출하므로서 구동모터(30)를 냉각하게 된다.At this time, heat is also generated in the drive motor 30 that rotates the cooling fan 20, but the air that hits the blades 22 by the air inlet 26 of the air guide member 25 formed in the cooling fan 20. By inhaling and leading to the air outlet 27, the drive motor 30 is cooled by strongly releasing it into the rib 24.

이렇게 구동모터(30)의 회전축(31) 방향에서 강하게 공기를 불어주므로서 구동모터(30)가 냉각되어 열해를 방지하게 된다.As the air is blown strongly in the direction of the rotation shaft 31 of the drive motor 30, the drive motor 30 is cooled to prevent thermal damage.

이상과 같이 공기유도부재가 형성된 냉각팬은 구동모터에 의해 냉각팬이 회전하면서 날개에 부딪치는 일부의 공기를 냉각팬 축수부 쪽으로 유도하여 강하게 방출하게 되므로서, 냉각팬을 구동하는 구동모터를 냉각하여 구동모터가 열해를 입는 것을 방지해서 구동모터의 수명을 연장하는 데 커다란 장점이 있는 것이다.As described above, the cooling fan in which the air induction member is formed is driven by the driving motor to induce some of the air colliding with the blades toward the cooling fan shaft part, thereby releasing it strongly, thereby cooling the driving motor for driving the cooling fan. Therefore, there is a great advantage in prolonging the life of the drive motor by preventing the drive motor from thermal damage.
