However, the present invention is not limited to the embodiments disclosed below, but will be implemented in various forms, and only the present embodiments are intended to complete the disclosure of the present invention and to those skilled in the art to fully understand the scope of the invention. It is provided to inform you.
도 1은 본 발명의 바람직한 실시예에 따른 메탄올 연료탱크의 잔량 표시장치를 개략적으로 도시한 도면이다.1 is a view schematically showing a remaining amount display device of a methanol fuel tank according to a preferred embodiment of the present invention.
도 1에 도시된 바와 같이, 본 발명에 따른 메탄올 연료탱크의 잔량 표시장치(100)는, 연료(11)가 내재되는 제1챔버(13)와 냉각수(17)가 내재되는 제2챔버(15)를 구비하는 연료탱크(10)와, 냉각수(17)의 온도를 센싱하는 온도센서(19)와, 연료탱크(10)의 제2챔버(15)와 연통되는 튜브부재(20)와, 상기 튜브부재(20)를 흐르는 냉각수(17)의 압력을 측정하는 압력센서(30)와, 연료(11)의 중량으로 잔존량을 도출하여 표시하는 제어부(40)와, 냉각수(17)를 순환시키는 펌프부재(50) 및 냉각팬(60)을 구비한다.As shown in FIG. 1, the remaining amount display device 100 of the methanol fuel tank according to the present invention includes a first chamber 13 in which the fuel 11 is embedded and a second chamber 15 in which the coolant 17 is embedded. A fuel tank (10) having a), a temperature sensor (19) for sensing the temperature of the cooling water (17), a tube member (20) in communication with the second chamber (15) of the fuel tank (10), and A pressure sensor 30 for measuring the pressure of the cooling water 17 flowing through the tube member 20, a control unit 40 for deriving and displaying the remaining amount by the weight of the fuel 11, and circulating the cooling water 17 A pump member 50 and a cooling fan 60 are provided.
상기 연료탱크(10)는 연료(11)가 내재되는 제1챔버(13) 및 냉각수(15)가 내재되는 제2챔버(17)를 구비한다. 상기 연료(11)는 메탄올을 말하며, 연료탱크(10)에는 이 메탄올을 통하여 수소로 얻어내는 미도시된 개질기가 장착된다. 상기 제1챔버(13)는 그 자중에 의하여 연료탱크(10)의 상하 방향으로 슬라이딩 가능하도록 설치된다. 상기 제2챔버(15)는 냉각수(17)가 내재되고 온도 센서(19)가 설치되어 냉각수(17)의 온도를 센싱하며, 상기 냉각수(17)는 제1챔버(13)의 자중에 의한 하강으로 가압되도록 내재된다. 즉, 상기 냉각수(17)는 제1챔버(13)에 내재된 연료(11)의 양에 따라 가압되는 정도가 달라지게 된다. 상기 냉각수(17)는 제2챔버(15)와 연통된 튜브부재(20)로 이동된다.The fuel tank 10 includes a first chamber 13 in which the fuel 11 is embedded and a second chamber 17 in which the coolant 15 is embedded. The fuel 11 refers to methanol, and the fuel tank 10 is equipped with a reformer (not shown) which obtains hydrogen through the methanol. The first chamber 13 is installed to be slidable in the vertical direction of the fuel tank 10 by its own weight. The second chamber 15 has a coolant 17 therein and a temperature sensor 19 is installed to sense the temperature of the coolant 17, and the coolant 17 is lowered by the weight of the first chamber 13. It is inherently pressurized by. That is, the degree to which the cooling water 17 is pressurized varies according to the amount of fuel 11 in the first chamber 13. The coolant 17 is moved to the tube member 20 in communication with the second chamber 15.
상기 튜브부재(20)는 제2챔버(15)와 연통되어 루프를 이루도록 설치되며, 압력센서(30)가 설치된다. 상기 압력센서(30)는 제어부(40)와 연결되어 튜브부재(20) 내부를 흐르는 냉각수(17)의 압력을 센싱하여 제어부(40)로 송신한다. The tube member 20 is installed in communication with the second chamber 15 to form a loop, and a pressure sensor 30 is installed. The pressure sensor 30 is connected to the control unit 40 senses the pressure of the coolant 17 flowing through the tube member 20 and transmits it to the control unit 40.
상기 제어부(40)는 냉각수(17)의 압력의 센싱신호를 수신받아 연료탱크(10)에 내재된 연료(11)의 양을 산출하는 ECU(41)와, 상기 ECU(41)에서 산출된 연료(11)의 양을 표시하는 계기판(43)으로 구비되어, 연료탱크(10)에 내재된 연료(11)의 양을 산출한다. 즉, 연료(11)가 내재된 제1챔버(13)는 연료(11)의 양에 따라 제2챔버(15)를 가압하는 압력이 상이하게 되며, 이러한 압력 값을 ECU(41)가 입력받아 제1챔버(13)에 내재된 연료(11)의 양을 산출하게 된다. The controller 40 receives the sensing signal of the pressure of the coolant 17 and calculates an amount of the fuel 11 in the fuel tank 10, and the fuel calculated by the ECU 41. It is provided with the instrument panel 43 which displays the quantity of (11), and calculates the quantity of the fuel 11 which is inherent in the fuel tank 10. FIG. That is, the pressure for pressurizing the second chamber 15 is different in the first chamber 13 having the fuel 11 embedded therein, and the ECU 41 receives the pressure value. The amount of fuel 11 inherent in the first chamber 13 is calculated.
상기 튜브부재(20)에는 냉각수(17)를 순환시키는 펌프부재(50) 및 냉각팬(60)이 구비됨으로써, 온도센서(19)에서 센싱된 냉각수(17)의 온도가 기 설정된 온도보다 높을 경우 냉각수(17)가 순환되도록 한다. The tube member 20 is provided with a pump member 50 and a cooling fan 60 for circulating the cooling water 17, so that the temperature of the cooling water 17 sensed by the temperature sensor 19 is higher than the preset temperature. Allow cooling water 17 to circulate.
즉, 상기 연료(11)는 메탄올로 이루어지는데, 이 메탄올은 낮은 끓는점을 갖음으로써, 기준 온도 이상의 온도값 이상으로 상승되면 쉽게 기화되는 성질을 갖는다. 이에 따라, 온도센서(19)는 냉각수(17)의 온도를 측정하여 센싱신호를 ECU(41)로 송신하고, ECU(41)는 냉각수(17)가 기준 온도값 이상으로 상승되었다고 판단되면 냉각수(17)를 순환시킴으로써, 메탄올의 연료가 기화되지 못하도록 한다.That is, the fuel 11 is made of methanol, which has a low boiling point, and thus has a property of easily vaporizing when it is raised above a temperature value above the reference temperature. Accordingly, the temperature sensor 19 measures the temperature of the coolant 17 and transmits a sensing signal to the ECU 41. When the ECU 41 determines that the coolant 17 rises above the reference temperature value, the coolant ( By circulating 17), the fuel of methanol is not vaporized.
상기의 구성을 갖는 본 발명에 따른 메탄올 연료탱크의 잔량 표시장치의 작동을 설명한다.The operation of the remaining amount display device of the methanol fuel tank according to the present invention having the above configuration will be described.
메탄올의 연료(11)가 연료탱크(10)의 제1챔버(13)로 유입되면, 제1챔버(13)는 그 자중에 의하여 연료탱크(10) 내에서 하강하면서, 제2챔버(15)의 냉각수(17)를 가압한다.When the fuel 11 of methanol flows into the first chamber 13 of the fuel tank 10, the first chamber 13 descends in the fuel tank 10 by its own weight, and the second chamber 15 The cooling water 17 is pressurized.
그러면, 가압된 냉각수(17)는 튜브부재(20)에 소정의 압력으로 유입되며, 이 냉각수(17)의 압력은 압력센서(30)에 의하여 측정되어 ECU(41)로 전달된다.Then, the pressurized coolant 17 is introduced into the tube member 20 at a predetermined pressure, and the pressure of the coolant 17 is measured by the pressure sensor 30 and transmitted to the ECU 41.
다음, ECU(41)는 냉각수(17)의 압력으로부터 제1챔버(13) 내의 연료의 잔존량을 산출하고, 산출된 연료(11)의 잔존량을 계기판(43)에 표시한다.Next, the ECU 41 calculates the remaining amount of fuel in the first chamber 13 from the pressure of the coolant 17, and displays the calculated remaining amount of the fuel 11 on the instrument panel 43.
또한, 온도센서(19)를 이용하여 상기 냉각수(17)의 온도가 기 설정된 값 이상으로 센싱되면, ECU(41)는 냉각팬(60) 및 펌프부재(50)를 작동시켜 냉각수(17)를 순환시킴으로써, 연료(11)의 기화됨을 방지한다.In addition, when the temperature of the cooling water 17 is sensed by using the temperature sensor 19 or more than a predetermined value, the ECU 41 operates the cooling fan 60 and the pump member 50 to operate the cooling water 17. By circulating, the vaporization of the fuel 11 is prevented.
상기와 같은 본 발명에 따른 메탄올 연료탱크의 잔량 표시장치는 다음과 같은 효과를 갖는다.The remaining amount display device of the methanol fuel tank according to the present invention as described above has the following effects.
메탄올 연료 탱크의 연료 잔존량을 제1챔버와 제2챔버를 구비한 연료탱크 및 압력센서를 통하여 비접촉식으로 측정할 수 있음으로써, 부식성의 메탄올의 연료 탱크 내의 잔존량을 효율적으로 측정할 수 있다.The fuel residual amount of the methanol fuel tank can be measured in a non-contact manner through a fuel tank having a first chamber and a second chamber and a pressure sensor, whereby the residual amount of corrosive methanol in the fuel tank can be efficiently measured.
또한, 냉각수의 순환을 통하여 메탄올의 연료가 기화됨을 방지한다.In addition, the fuel of methanol is prevented from vaporizing through the circulation of the cooling water.
