본 발명은 자동차용 VCP에 관한 것으로, 특히 차 내부의 온도 상승이나 기기의 동작중 발생하는 열로 자동차용 VCP가 과열되어 오동작 하거나 파손되는 것을 방지하기에 적당하도록 한 자동차용 VCP의 과열 방지용 팬구동 자동 제어장치에 관한 것이다.The present invention relates to an automotive VCP, and in particular, to prevent the vehicle VCP from overheating and malfunction or damage due to the heat generated during the temperature increase of the vehicle or the operation of the device. It relates to a control device.
종래에는 자동차 내부의 온도가 상승하거나 기기의 주변 온도가 상승하여도 온도를 내리기 위한 특별한 방열대책이 없었으며, 단지 온도특성이 상용 부품보다 양호한 부품을 사용하여 제품의 신뢰성을 확보하고 있으나, 이는 충분한 신뢰성을 확보하지 못할 뿐만 아니라 원가가 상승하게 되는 결점이 있다.Conventionally, there is no special heat dissipation measure to lower the temperature even if the temperature inside the car rises or the ambient temperature rises, and the reliability of the product is secured by using parts with better temperature characteristics than commercial parts. Not only does it fail to secure reliability, but it also has the drawback of rising costs.
따라서, 본 발명은 상기의 결점을 해결하기 위하여 안출한 것으로, 본 발명의 목적은 차 내부의 온도 상승이나 기기의 동작중 발생하는 열로 인한 자동차용 VCP가 과열되어 오동작하거나 파손되는 것을 방지할 수 있는 자동차용 VCP의 과열 방지용 팬구동 자동 제어장치를 제공하는데 있다.Accordingly, the present invention has been made to solve the above-mentioned drawbacks, and an object of the present invention is to prevent the vehicle VCP from overheating due to heat generated during operation of the device or the operation of the device to prevent malfunction or damage. It is to provide a fan drive automatic control device for preventing overheating of a vehicle VCP.
상기의 목적을 달성하기 위하여 본 발명에 따르면, 자동차용 VCP의 과열을 방지하는 장치에 있어서, 기기내의 온도를 감지하기 위한 온도 감지부(1)와, 상기 온도 감지부(1)에 의해 감지된 온도를 그 크기에 따라 전자회로에서 사용가능한 신호로 변환시키는 변화부(2)와, 상기 변화부(2)로부터 입력된 감지된 온도값과 기준 온도에 의해서 미리 설정된 온도값을 비교하여 그 차에 따른 팬구동 신호를 출력하는 마이컴(3)과, 상기 마이컴(3)으로부터 출력되는 팬구동 신호의 크기에 따라 팬의 회전속도를 제어하는 팬구동 제어부(4)로 이루어진 자동차용 VCP의 과열 방지용 팬구동 자동 제어장치를 제공한다.In order to achieve the above object, according to the present invention, in the device for preventing overheating of the automotive VCP, the temperature sensing unit 1 for sensing the temperature in the device, and the temperature sensing unit 1 The change unit 2 converts the temperature into a signal usable in the electronic circuit according to its magnitude, and compares the detected temperature value input from the change unit 2 with a preset temperature value based on the reference temperature. Fan for overheat prevention of the automotive VCP comprising a microcomputer (3) for outputting the fan drive signal according to the fan drive control unit (4) for controlling the rotation speed of the fan in accordance with the magnitude of the fan drive signal output from the microcomputer (3) It provides a driving automatic control device.
이하, 본 발명의 실시예를 첨부된 도면을 참조하여 상세히 설명하면 다음과 같다.Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
제 1 도는 본 발명의 자동차용 VCP의 과열 방지용 팬구동 자동 제어장치는 온도 감지부(1)와, 변환부(2), 마이컴(3) 및 팬구동 제어부(4)로 구성된다.1 is a fan driving automatic control apparatus for preventing overheating of a vehicle VCP according to the present invention comprises a temperature sensing unit 1, a converting unit 2, a microcomputer 3 and a fan driving control unit 4.
온도 감지부(1)는 기기내의 온도를 감지하여 이 감지된 온도를 후술하는 변환부(2)로 제공하도록 구성된다.The temperature sensing unit 1 is configured to sense the temperature in the device and provide this detected temperature to the converting unit 2 which will be described later.
변환부(2)는 온도 감지부(1)로부터 감지된 온도를 전자회로에서 사용가능한 신호로 변환시킨 다음 후술하는 마이컴(3)으로 제공하도록 구성된다.The converting unit 2 is configured to convert the temperature sensed by the temperature sensing unit 1 into a signal usable in an electronic circuit and then provide the microcomputer 3 to be described later.
마이컴(3)은 변환부(2)로부터 제공되는 온도값과 기준 온도에 의해 미리 설정된 온도값을 비교하여 그 차에 따른 팬구동 신호를 후술하는 팬구동 제어부(4)로 제공하도록 구성된다.The microcomputer 3 is configured to compare the temperature value provided from the conversion unit 2 with the temperature value preset by the reference temperature, and provide the fan drive signal according to the difference to the fan drive control unit 4 described later.
팬구동 제어부(4)는 마이컴(3)으로부터 출력되는 팬구동 신호의 크기에 따라 팬의 회전속도를 제어하도록 구성된다.The fan drive control unit 4 is configured to control the rotation speed of the fan according to the magnitude of the fan drive signal output from the microcomputer 3.
이와 같이 구성된 본 발명은 기기내의 온도가 상승하면 온도 감지부(1)에서 그 온도를 감지하여 변환부(2)로 보낸다.According to the present invention configured as described above, when the temperature in the device rises, the temperature sensor 1 senses the temperature and sends the temperature to the converter 2.
변환부(2)에서는 감지된 온도를 그 크기에 따라 전자회로에서 사용가능한 형태, 즉 마이컴(3)이 인식할 수 있는 신호 형태로 변화시킨다.The converting unit 2 changes the sensed temperature into a form usable in an electronic circuit, that is, a signal form that the microcomputer 3 can recognize according to its magnitude.
따라서, 마이컴(3)에서는 감지된 온도값(이를 A라 한다)과 기준 온도에 의해 미리 설정된 온도값(이를 B라 한다)을 비교한 결과, 감지된 온도값(A)이 미리 설정된 온도의 값(B)보다 작으면(A<B), 팬을 구동시키지 않고 다시 기기내의 온도를 감지하도록 제어한다.Therefore, the microcomputer 3 compares the detected temperature value (this is A) with the temperature value preset by the reference temperature (this is B), and as a result, the detected temperature value A is the value of the preset temperature. If it is smaller than (B) (A <B), it controls to sense the temperature inside the apparatus again without driving the fan.
이와 반대로, 감지된 온도값(A)이 미리 설정된 온도의 값(B)보다 크면(A>B), 그 차(A-B)에 따른 출력신호의 크기를 결정하여 이를 팬구동 제어부(4)로 출력시킨다.On the contrary, when the detected temperature value A is greater than the preset temperature value B (A> B), the magnitude of the output signal according to the difference AB is determined and outputted to the fan driving controller 4. Let's do it.
팬구동 제어부(4)에서는 마이컴(3)으로부터 출력된 신호의 크기에 따라 팬의 회전속도를 제어하여 구동시킴으로써 기기내의 상승된 온도가 내려가게 되는 것이다.The fan drive control unit 4 controls and drives the rotational speed of the fan in accordance with the magnitude of the signal output from the microcomputer 3 to lower the elevated temperature in the device.
이상에서 설명한 바와같이 본 발명은 차 내부의 기기의 온도가 상승할 때 이를 감지 및 비교하여 팬을 구동시키는 수단에 의해 열을 자동으로 내려줄 수 있어 제품에 대한 충분한 범위의 신뢰성을 확보할 수 있음은 물론 종래와 같이 원가를 상승시키는 요인이 되는 단지 온도 특성이 양호한 부품을 사용할 필요가 없어져 원가를 절감할 수 있는 효과가 있다.As described above, the present invention can automatically lower the heat by means of driving the fan by detecting and comparing when the temperature of the device inside the car rises, thereby securing a sufficient range of reliability for the product. Of course, there is no need to use a component having a good temperature characteristic, which is a factor that increases the cost as in the prior art, thereby reducing the cost.
