Description

자동차 라디에이터 팬 작동불량상태 경보장치Car Radiator Fan Malfunction Alarm

본 고안은 자동차 라디에이터 팬 작동불량상태 경보장치에 관한 것으로, 더 상세하게는 자동차 운행중 라디에이터 팬이 벨트 훼손과 기구 부식이나 모터소손 등의 이유로 회전되지 않을시 이를 감지하여 운전자에게 경보하여 줌으로서 엔진이 과열되지 않도록 한 것이다.The present invention relates to a car radiator fan malfunction status alarm device, and more specifically, when the radiator fan is not rotated due to belt damage, mechanism corrosion, motor burn, etc., the engine detects this and alerts the driver. It does not overheat.

종래 ECM시스템의 차량에 있어서, 라디에이터 팬의 동작과 무관하게 시그날을 출력하여 팬이 어떤 불완전한 요인으로 동작하지 않아도 팬이 동작하고있는 것으로 인식함으로 엔진을 냉각하지 못하는 상태에서 운행되어 엔진이 과열하여 더욱 심한 피해를 입고 있다.In the vehicle of the conventional ECM system, regardless of the operation of the radiator fan, the signal is output so that the fan is operating even if the fan does not operate due to any incomplete factors. I am doing severe damage.

일반적으로 팬은 물 펌프와 함께 조립되어 있으며, 크랭크축 플리를 동력원으로 하는 벨트에 의해 구동되며, 엔진의 주변을 순환하여 온도가 높아진 냉각수를 라디에이터를 통과하는 공기에 의해 냉각시키므로 냉각수의 온도를 유지한다.Typically, the fan is assembled with a water pump, driven by a belt powered by the crankshaft fleet, and circulated around the engine to cool the cooled water by the air passing through the radiator to maintain the temperature of the coolant. do.

이 때에 라디에이터를 통과하는 공기의 속도가 빠르면 방열 효과는 좋아진다.At this time, if the speed of air passing through the radiator is high, the heat dissipation effect is improved.

자동차가 규정의 속도를 주행하고 있을 때에는 라디에이터의 전면에 주행풍이 닿기 때문에 충분히 냉각되지만 저속으로 주행하거나 정차중의 아이들링 상태에서는 냉각이 잘 안되므로 어떠한한 상태에서도 냉각이 잘 되도록 라디에이터의 후부 2030cm의 위치에 팬을 설치하여 강제적으로 공기를 흡수한다.When the car is driving at the specified speed, the front of the radiator is cool enough because the running wind touches it, but it is not cooled well at low speed or idling while stopping. Install a fan to absorb air forcibly.

팬은 얇은 강판을 프레스 성형해서 만들며, 2030°의 각도로 붙인 팬은 2, 4, 6개로 되어 있으며, 팬 원호의 반지름은 120140mm 정도로 한다.The fan is made by press forming a thin steel plate, and there are 2, 4, and 6 pans attached at an angle of 2030 °, and the radius of the fan arc is about 120140 mm.

팬은 고속 회전을 하면 바람의 저항이 커지기 때문애 소음이 커지게 된다. 팬의 소음 원인은 맴돌이에 의한 것과 불균형 때문에 일어나는 팬의 진동에 의한 것이 있으며, 팬의 형태에 따라 동일 지름 또는 동일 개수라도 같은 송풍량을 만들기 위해서는 소음량도 달라진다.When the fan rotates at high speed, the wind resistance increases, which increases the noise. The noise of the fan is caused by the eddy and the vibration of the fan due to the imbalance, and the amount of noise varies even if the same diameter or the same number of air blows, depending on the shape of the fan.

팬의 회전 속도와 차의 속도에 의해 냉각 공기량의 통과량이 달라지지만, 저속시에는 그 필요량을 확보하기 위해서 코어를 통과하는 풍속은 최소 8 ∼ 10m/s 정도가 필요하다.Although the amount of passage of cooling air varies depending on the rotational speed of the fan and the speed of the car, at a low speed, at least 8 to 10 m / s is required for the wind speed passing through the core to secure the required amount.

따라서 엔진의 회전 속도와 팬의 회전 속도는 구동축에 있는 크랭크 풀리와 팬 풀리의 지름에 의해 결정되며, 엔진의 회전 속도 0.8∼1.5배가 되도록 설계되어 있다.Therefore, the rotational speed of the engine and the rotational speed of the fan are determined by the diameters of the crank pulley and the fan pulley in the drive shaft, and are designed to be 0.8-1.5 times the rotational speed of the engine.

팬의 지름은 라디에이터 전면의 면적(라디에이터 코어의 면적)에 의해 제한되므로 반지름으로 말하면 20∼400mm 정도이며, 팬의 형태와 개수가 같으면 흡입 능력은 팬의 지름과 엔진의 회전수에 따라 결정된다.Since the diameter of the fan is limited by the area of the front of the radiator (the area of the radiator core), the radius is about 20 to 400 mm. If the fan is the same shape and number, the suction capacity is determined by the diameter of the fan and the engine speed.

또한 출력의 감퇴나 과도 냉각이라는 문제가 있으므로 어느정도 이상의 회전이 안되도록 유체 접수(fluid coupling)나 라디에이터의 냉각 온도가 규정 온도 이상이 안되면 팬이 회전하지 않는 수온 조절기 등이 있다.In addition, there is a problem such as decay of output or overcooling, such as a fluid coupling or a water temperature controller in which the fan does not rotate when the cooling temperature of the radiator does not exceed a specified temperature so that it does not rotate more or less.

이러한 종래 라디에이터 팬 시스템에 있어서 팬이 작동하지 않는 상태로 운행될때는 상기의 역작용으로서 엔진이 과열되서 화재의 사고뿐 아니라 엔진의 수명이 단축되는 등의 심한 손실을 당하게된다.In such a conventional radiator fan system, when the fan is operated in a non-operating state, the engine is overheated as a reverse action, and suffers a severe loss such as not only a fire accident but a shortened engine life.

본 고안은 상기한 결점에 감안한다.The present invention contemplates the above drawbacks.

본 고안은 ECM에서 라디에이터 팬모터의 Low와 High 시그날을 감지하는 팬 동작검출기와 팬모터 자체의 회전을 감지하는 엔코더와 팬 동작검출기의 출력신호를 받아 점등되는 크루스터에 장착전 경고등으로 구성되어서 팬이 작동하지 않을 시 즉각 경고등이 점등되어 운전자가 보수할 수 있는 회로로서 완성되어 있다.This design consists of fan motion detector which detects low and high signal of radiator fan motor in ECM, encoder which detects rotation of fan motor itself, and warning light before installation on the cruster which is turned on by output signal of fan motion detector. If this does not work, the warning light turns on immediately, and the circuit is ready for the driver to repair.

도 1 은 본 고안의 전체 회로도이고, 도 2 는 본 고안의 작동 플로우챠트이다.1 is an overall circuit diagram of the present invention, Figure 2 is an operational flowchart of the present invention.

ECM에서 Low 팬, High 팬에 인가된 라디에이터 모터(M)에 엔코더(E)가 근접설치되고 이것이 팬 동작검출기(1)에 연결된다.In the ECM, the encoder E is installed close to the radiator motor M applied to the low fan and the high fan, which is connected to the fan motion detector 1.

팬 동작검출기(1)은 상기한 Low 팬, High 팬 신호에 병열연결되고 그 출력단이 크루스터에 장착된 팬 작동경고등(L)에 연결 접속된 구성으로 되어 있다.The fan motion detector 1 has a configuration in which the fan motion detector 1 is connected in parallel with the low fan and high fan signals and the output end thereof is connected to the fan operation warning lamp L mounted on the cluster.

이와같이 된 본고안의 작동상태를 설명한다.This section describes the operational status of this article.

도 2의 플로우챠트와 같이 팬모터가 동작하는지 검출할 수 있는 센서로서 엔코더를 장착하여 동작시 신호및 펄스를 받아 Low High 팬 시그날이 들어오고 모터 동작이 되면 OK, 그러나 모터동작이 되지않으면 경고등이 점등되어 운전자가 즉각 운행을 중단하고 라디에이터 팬 부위를 점검, 정비 할수 있게하여 엔진의 과열을 방지할 수 있는 것이다.As shown in the flowchart of FIG. 2, the encoder is equipped with an encoder to detect whether the fan motor is operating, receives a signal and a pulse during operation, receives a low high fan signal, and the motor is OK. However, if the motor is not operated, a warning lamp is provided. It lights up so that the driver can stop the operation immediately and check and repair the radiator fan to prevent the engine from overheating.

본 고안은 자동차 라디에이터 팬이 벨트 훼손과 기구부식이나 모터소손 등의 이유로 회전되지 않을 때 이를 감지하여 운전자에게 경보하여 줌으로서 엔진의 과열을 방지하여 차량 화재사고나 엔진의 수명 단축을 사전에 예방할 수 있는 유용한 고안이다.The present invention detects when the radiator fan is not rotated due to belt damage, mechanical corrosion or motor damage, and alerts the driver to prevent overheating of the engine, thereby preventing vehicle fire accidents and shortening of engine life. That is a useful design.
