It is about.
일반적으로 차량에는 각종 전기 및 전자기기를 장착하고 이들은 발전기와 축전지로부터 공급되는 전력에 의하여 작동되도록 되어 있으며, 상기 전력의 안정된 공급을 위하여 발전기를 중심으로 하는 충전장치를 구비하고 있고, 상기 발전기는 직류발전기와 교류발전기가 이용되고 있으나, 저속 및 고속에서도 안정성을 유지하는 교류발전기가 보다 널리 이용되고 있으며 이는 하우징(1)의 내부에 브러쉬 어셈블리(2), 스테이터 어셈블리(3), 로터 어셈블리(4) 및 베어링과 풀리(5) 등으로 구성되어 있다.In general, the vehicle is equipped with a variety of electrical and electronic devices and they are to be operated by the power supplied from the generator and the storage battery, and is provided with a charging device centered on the generator for the stable supply of the power, the generator is a direct current Generators and alternators are used, but alternators that maintain stability at low and high speeds are more widely used, which includes a brush assembly (2), a stator assembly (3), and a rotor assembly (4) inside the housing (1). And a bearing, a pulley 5 and the like.
한편, 상기와 같이 구성된 종래의 것은 도 1에서와 같이 교류발전기의 작동시 발생하는 열을 냉각시키기 위해서 풀리(5)의 내측에 팬(Fan)을 설치하거나 상기 스테이터 어셈블리의 슬립링 일방에 냉각팬을 설치하고 이 팬의 동작으로 발생된 냉각풍이 상기 교류발전기의 내부를 순환하면서 냉각작용을 하는 공냉식으로 되어 있었다.On the other hand, the conventional configuration configured as described above, as shown in Figure 1 in order to cool the heat generated during the operation of the alternator installed a fan (Fan) inside the pulley (5) or a cooling fan on one side of the slip ring of the stator assembly The cooling air generated by the operation of the fan was circulated inside the alternator, thereby cooling the air.
그러나, 상기와 같은 종래의 것은 냉각팬을 이용한 공냉식으로 구성되어 있었기 때문에 상기 냉각팬을 설치하기 위한 구조가 복잡하게 되어 있었고 또, 구조의 복잡성으로 인하여 발전기 전체의 부피가 커지게 되는 폐단이 있었으며, 상기 냉각팬의 구동에 의한 바람이 회전체에 부딪히면서 풍음을 발생시키게 되어 발전기의 구동시 소음이 발생하게 되는 문제점이 있었고 또한, 엔진 등의 열에 의한 엔진룸의 열이 비교적 고열이기 때문에 상기 공냉을 위한 공기가 자체의 열로 인해 충분한 냉각기능을 발휘하기 어렵게 되어 냉각효율이 크게 저하되고 있는 점 등의 문제점이 있었다.However, since the conventional one is composed of air cooling using a cooling fan, the structure for installing the cooling fan is complicated, and due to the complexity of the structure, there is a closed end in which the entire volume of the generator is increased. The wind caused by the driving of the cooling fan hits the rotating body to generate wind noise, there was a problem that the noise generated when driving the generator, and because the heat of the engine room by the heat of the engine is relatively high heat for the air cooling There is a problem that the air is difficult to exhibit a sufficient cooling function due to its own heat, and the cooling efficiency is greatly reduced.
본 발명은 상기와 같은 종래의 제반 결점을 감안하고 이를 해소하기 위하여 안출한 것으로, 상기 차량용 교류발전기의 브라켓트에 냉각수로를 형성하고 이 냉각수로를 통해 엔진의 냉각수를 공급하면서 상기 교류발전기를 수냉방식으로 냉각시키도록하여 냉각효율을 향상시킬 수 있도록 한 차량용 발전기의 냉각시스템을 제공하려는 것인바, 이를 이하에서 첨부한 도면과 실시예에 의거하여 상세하게 설명하면 다음과 같다.The present invention has been made in view of the above-mentioned conventional drawbacks and solves the above-mentioned problems, and forms a cooling water passage in the bracket of the vehicle alternator and supplies the cooling water of the engine through the cooling water passage, while the alternator is water-cooled. It is to provide a cooling system for a vehicle generator to improve the cooling efficiency by cooling to the bar, which will be described in detail based on the accompanying drawings and examples below.

And the discharge unit 9 is configured by connecting to the supply means for supplying the cooling water of the engine.
이상과 같이 구성된 본 발명은 상기 교류발전기의 하우징(1)에 설치되는 상기 브라켓트(6)에 냉각수가 흐를 수 있는 냉각수로(7)를 형성하고 이 냉각수로(7)에는 냉각수를 공급하는 공급부(8)와 냉각된 물을 배출하기 위한 배출부(9)를 형성하며 이들 공급부(8)와 배출부(9)는 엔진의 냉각수가 공급되는 공급수단에 연결,설치하여 구성하므로써 엔진의 라디에이터에 의해 냉각된 냉각수가 상기 냉각수로(7)의 공급부(8)를 통해 상기 브라켓트(6)로 공급되고 이 공급된 냉각수가 순환하면서 상기 교류발전기를 냉각시키게 되며 냉각작용이 완료된 물은 상기 배출부(9)를 통하여 엔진의 라디에이터로 배출되어 다시 냉각되도록 된 것이다.The present invention configured as described above forms a cooling water passage (7) through which the cooling water can flow in the bracket (6) installed in the housing (1) of the alternator, and the supply unit for supplying cooling water to the cooling water passage (7) ( 8) and a discharge part 9 for discharging the cooled water, and the supply part 8 and the discharge part 9 are connected to and installed by a supply means through which the engine's cooling water is supplied. Cooled cooling water is supplied to the bracket 6 through the supply part 8 of the cooling water passage 7, and the supplied cooling water circulates to cool the alternator, and cooling water is completed in the discharge part 9 ) Is discharged to the radiator of the engine to cool again.
따라서, 상기 엔진의 냉각수단에 의하여 냉각되는 냉각수를 상기 교류발전기로 순환 공급하여 발전기를 냉각시킬 수 있게 되고 상기 하우징(1)의 내부에 설치된 브러쉬 어셈블리(2), 스테이터 어셈블리(3), 로터 어셈블리(4) 및 베어링과 풀리(5), 후방 브라켓트(6)를 충분히 냉각시킬 수 있게 되는 것이다.Accordingly, the coolant cooled by the cooling means of the engine may be circulated and supplied to the alternator to cool the generator, and the brush assembly 2, the stator assembly 3, and the rotor assembly installed inside the housing 1 may be cooled. (4) and the bearing, the pulley (5), and the rear bracket (6) can be sufficiently cooled.
이상과 같은 본 발명은 상기와 같은 엔진을 냉각시키는 냉각수를 상기 교류발전기의 브라켓트(6)에 형성시킨 냉각수로(7)에 공급하여 순환시키므로써 상기 순환되는 냉각수에 의하여 교류발전기를 수냉식으로 효율적으로 냉각시킬 수 있게 되며 , 상기 수냉식의 구조를 형성함에 따라 종래와 같이 공냉을 위한 냉각팬 등의 구성이 필요없게 되고 이 구조물이 없게 되므로써 상기 발전기의 구조를 보다 간단하게 하면서 전체적인 부피를 크게 줄일 수 있게 된다.The present invention as described above is supplied to the cooling water passage (7) formed in the bracket 6 of the alternator for cooling the engine as described above by supplying and circulating the alternator is water-cooled efficiently by the circulated cooling water It is possible to cool, and by forming the water-cooled structure, there is no need for a configuration such as a cooling fan for air cooling as in the prior art, and since there is no structure, it is possible to simplify the structure of the generator and to greatly reduce the overall volume. do.
또, 상기 수냉식으로 발전기를 냉각시키면서도 이 냉각을 위한 냉각수를 엔진에 설치되는 라디에이터에서 상시 냉각시키면서 공급하게 되므로 엔진룸의 자체열이 높게 상승되더라도 이 온도에 크게 영향을 받지않고 냉각작용을 할 수 있게 되며, 바람을 이용하지 않으므로 종래와 같은 풍음에 의한 소음을 방지할 수 있게 되며 냉각효율을 크게 향상시켜 교류발전기의 특성을 향상시킬 수 있게 되는 점 등의 특징을 지닌 것이다.In addition, while cooling the generator by the water-cooled, the cooling water for this cooling is always supplied by the radiator installed in the engine, so that even if the heat of the engine room rises high, the cooling function can be performed without being greatly affected by this temperature. Since the wind is not used, the noise due to the wind can be prevented as in the related art, and the cooling efficiency can be greatly improved, and the characteristics of the alternator can be improved.
