Description

보조온도센서를 갖춘 냉각장치Cooling system with auxiliary temperature sensor

본 고안은 보조온도센서를 갖춘 냉각장치에 관한 것으로, 보다 상세하게는 주행중 온도센서가 제기능을 수행하지 못할 경우에 보조온도센서에 의한 감지동작이 행해지도록 한 보조온도센서를 갖춘 냉각장치에 관한 것이다.The present invention relates to a cooling device having an auxiliary temperature sensor, and more particularly, to a cooling device having an auxiliary temperature sensor to perform a sensing operation by the auxiliary temperature sensor when the temperature sensor fails to function during driving. will be.

일반적으로, 차량에는 작동중 엔진이 과열되지 않도록 적당한 온도를 유지시키는 냉각장치가 채용되어 있고, 그 냉각장치에는 실린더블럭과 실린더헤드에 설치된 물통로(Water Jacket)와, 냉각수를 순환시키는 물펌프(Water Pump), 벨트, 엔진에서 뜨거워진 냉각수를 방열판에 통과시켜 공기와 접촉하게 하는 라디에이터, 엔진과 라디에이터사이에 설치되며 라디에이터의 뜨거운 냉각수가 통과할 때 공기를 강제로 빨아들여 라디에이터의 냉각효과를 증대시킴과 더불어 배기다기관의 과열도 방지하는 냉각휀, 냉각수온도를 감지하는 온도센서 등이 갖추어진다.In general, a vehicle employs a cooling device that maintains an appropriate temperature to prevent the engine from overheating during operation. The cooling device includes a water jacket installed in a cylinder block and a cylinder head, and a water pump circulating cooling water. Water pump), a radiator that allows hot water from the belt and engine to pass through the heatsink to contact air, and is installed between the engine and the radiator and forcibly sucks air when the hot water of the radiator passes through to increase the radiator's cooling effect. In addition to the cooling system, a cooling fan to prevent overheating of the exhaust manifold and a temperature sensor to detect the coolant temperature are provided.

따라서 종래의 냉각장치의 경우 도 1에 도시된 바와 같이 온도센서(10)에서 감지되는 냉각수의 온도가 소정치(예컨대, 106℃) 정도이면 ECM(12)이 고속웬릴레이(14)를 활성화시키게 되고, 그로 인해 냉각휀(도시 생략)이 고속으로 회전하여 냉각수의 온도를 낮추어 주어 엔진 등에 무리가 가해지지 않도록 한다.Accordingly, in the case of the conventional cooling apparatus, as shown in FIG. 1, when the temperature of the cooling water sensed by the temperature sensor 10 is about a predetermined value (for example, 106 ° C.), the ECM 12 activates the fast wen relay 14. As a result, the cooling fan (not shown) rotates at a high speed to lower the temperature of the cooling water so that it is not applied to the engine or the like.

그런데, 주행중 냉각수온도의 온도센서(10)의 소자열화로 인해 제기능을 수행하지 못할 경우 냉각휀은 계속 고속으로 작동하게 되고, 초기시동시에도 냉각휀은 계속 회전하기 때문에 정비센터가 근처에 없는 지역에서는 신속한 정비가 행해지지 않게 되어 엔진에 무리가 가해질 뿐만 아니라 부품손상의 우려가 있다.However, the cooling fan continues to operate at high speed if the function of the temperature sensor 10 of the coolant temperature is deteriorated while driving, and the cooling fan continues to rotate at the initial startup. In the region, rapid maintenance is not carried out, which not only damages the engine but also damages components.

따라서 본 고안은 상기한 사정을 감안하여 이루어진 것으로, 그 목적은 주행중 온도센서가 제기능을 수행하지 못할 경우에 보조온도센서에 의한 감지동작이 행해지도록 함으로써 엔진에 무리가 가해지지 않도록 한 보조온도센서를 갖춘 냉각장치를 제공함에 있다.Therefore, the present invention has been made in view of the above circumstances, and its object is to provide a subsidiary temperature sensor that prevents the engine from being applied to the engine by performing a sensing operation by the auxiliary temperature sensor when the temperature sensor fails to perform its function while driving. To provide a cooling device equipped with.

상기한 목적을 달성하기 위해 본 고안의 바람직한 실시예에 따르면, 온도센서에서 감지되는 신호를 기초로 고속휀릴레이를 작동시키는 ECM을 갖춘 냉각장치에 있어서,According to a preferred embodiment of the present invention to achieve the above object, in the cooling device having an ECM for operating a high-speed relay on the basis of the signal detected by the temperature sensor,

상기 온도센서의 감지영역이상의 온도범위를 감지하는 보조온도센서 및, 그 보조온도센서의 작동시 상기 ECM의 제어하에 점등되는 경고등이 추가로 구성된 보조온도센서를 갖춘 냉각장치가 제공된다.There is provided a cooling apparatus having an auxiliary temperature sensor configured to detect a temperature range above the sensing area of the temperature sensor, and an auxiliary temperature sensor further configured with a warning light that is turned on under the control of the ECM when the auxiliary temperature sensor operates.

이하, 첨부된 도면을 참조하여 본 고안의 실시예에 대해 더욱 상세히 설명한다.Hereinafter, with reference to the accompanying drawings will be described in detail an embodiment of the present invention.

도 2는 본 고안의 실시예에 따른 보조온도센서를 갖춘 냉각장치의 구성을 나타낸 도면으로서, 도 1에서 설명한 부분과 동일한 구성요소에 대해서는 참조부호를 동일하게 부여하면서 그에 대한 설명은 생략한다.2 is a view showing the configuration of a cooling device having an auxiliary temperature sensor according to an embodiment of the present invention, the same reference numerals are given to the same components as those described in FIG.

본 고안의 실시예에서는 보조온도센서(16)와 경고등(18)이 추가로 구비됨이 종래의 구성과의 차이점이다.In the embodiment of the present invention, the auxiliary temperature sensor 16 and the warning light 18 is further provided is a difference from the conventional configuration.

그 보조온도센서(16)는 온도센서(10)의 감지영역이상의 온도범위(예컨대, 110℃∼115℃이상까지 가능)를 센싱할 수 있다.The auxiliary temperature sensor 16 may sense a temperature range (eg, up to 110 ° C. to 115 ° C. or more) above the detection area of the temperature sensor 10.

그리고, 경고등(18)은 온도센서(10)가 제기능을 하지 못하고 보조온도센서(16)가 동작할 때 ECM(12)의 제어하에 점등되는 바, 그 경고등(18)은 운전석 전방의 인스트루먼트 패널(도시 생략)상에 설치될 수 있다.Then, the warning lamp 18 is turned on under the control of the ECM 12 when the temperature sensor 10 is not functioning and the auxiliary temperature sensor 16 operates, and the warning lamp 18 is the instrument panel in front of the driver's seat. (Not shown).

이어, 상기와 같이 구성된 본 고안의 실시예에 따른 보조온도센서를 갖춘 냉각장치에 따르면, 일단 차량이 주행하게 되면 라디에이터내부의 냉각수 온도는 온도센서(10)에 의해 감지되는데, 그 감지되는 냉각수 온도가 그 온도센서(10)의 감지영역이라면 그 온도센서(10)의 감지기능이 제대로 행해지게 되어 그 온도센서(10)에서 감지되는 신호를 기초로 ECM(12)은 고속휀릴레이(14)를 동작시켜 냉각휀을 고속회전시키게 된다.Then, according to the cooling device having an auxiliary temperature sensor according to an embodiment of the present invention configured as described above, once the vehicle is running, the coolant temperature inside the radiator is detected by the temperature sensor 10, the detected coolant temperature Is a sensing area of the temperature sensor 10, the sensing function of the temperature sensor 10 is properly performed so that the ECM 12 generates a high-speed relay 14 based on the signal detected by the temperature sensor 10. In operation, the cooling fan rotates at high speed.

그런데, 라디에이터내부의 냉각수 온도가 그 온도센서(10)의 감지영역밖이 되었다거나(이 경우 온도센서(10)의 소자열화가 발생됨) 그로 인한 온도센서(10)의 고장시 ECM(12)은 보조온도센서(16)를 작동시킴과 더불어 경고등(18)을 점등시켜 현재 온도센서(10)가 고장났음을 알리게 되고, 냉각휀의 고속작동기능을 삭제하게 된다. 그리고 나서, 그 ECM(12)은 보조온도센서(16)를 작동시키게 되고, 그 보조온도센서(16)에서 감지되는 신호를 기초로 고속휀릴레이(14)를 작동시켜 냉각휀을 고속회전시키게 된다.However, when the temperature of the coolant inside the radiator is outside the sensing area of the temperature sensor 10 (in this case, deterioration of the device of the temperature sensor 10 occurs) or a failure of the temperature sensor 10 due to this, the ECM 12 In addition to operating the auxiliary temperature sensor 16 and lighting the warning light 18 to inform that the current temperature sensor 10 has failed, and deletes the high-speed operation of the cooling fan. Then, the ECM 12 operates the auxiliary temperature sensor 16, and operates the high speed fan relay 14 based on the signal sensed by the auxiliary temperature sensor 16 to rotate the cooling fan at high speed. .

이상 설명한 바와 같은 본 고안에 의하면, 온도센서가 고장나더라도 보조온도센서가 제기능을 발휘하게 되므로, 온도센서의 고장시 냉각휀의 무리한 고속회전으로 인한 엔진손상을 미연에 방지할 수 있게 된다.According to the present invention as described above, even if the temperature sensor is broken, the auxiliary temperature sensor can function properly, so that engine damage due to excessive high speed rotation of the cooling fan can be prevented in advance when the temperature sensor is broken.
