Description
본 발명은 수소 자동차의 메탈 하이드라이드 탱크(Metal Hydride Tank)의 초기 가열 장치에 관한 것으로, 더욱 상세하게 설명하면, 메탈 하이드라이드 탱크내에 전기 히터 및 온도센서를 내설하여 일정온도 이하일 경우 전기 히터를 작동시켜 수소의 공급 압력을 증대시키도록 함으로서 냉간 시동 및 초기 시동시 엔진의 구동을 효율적으로 실행할 수 있도록 하는 것이다.The present invention relates to an initial heating device of a metal hydride tank (metal hydride tank) of a hydrogen vehicle, in more detail, the electric heater and the temperature sensor in the metal hydride tank by operating the electric heater when the temperature is below a certain temperature By increasing the supply pressure of hydrogen, the engine can be efficiently driven during cold start and initial start.
종래 수소자동차의 연료(수소) 저장용으로 사용되는 탱크는 사용이 안전한 장점으로 인하여 메탈 하이드라이드 탱크를 사용하고 있다.Conventionally, a tank used for storing fuel (hydrogen) of a hydrogen vehicle uses a metal hydride tank due to its safe use.
그런데, 메탈 하이드라이드는 수소를 아주 잘 흡수하는 금속 및 수소의 화합물로 이루어져 있어 공급되는 수소의 압력이 온도의 함수로 결정되는 특성이 있다. 따라서, 도 1에 도시한 바와 같이 메탈 하이드라이드 탱크(T)에 엔진의 냉각수 또는 배개가스를 상기 메탈 하이드라이드 탱크(T)주위로 순환시켜 메탈 하이드라이드 탱크(T)의 온도를 일정온도(60∼70℃)로 유지시키고 있다.However, the metal hydride is composed of a metal and a compound of hydrogen that absorbs hydrogen very well, so that the pressure of hydrogen supplied is determined as a function of temperature. Accordingly, as shown in FIG. 1, the cooling water or the exhaust gas of the engine is circulated around the metal hydride tank T in the metal hydride tank T to maintain the temperature of the metal hydride tank T at a predetermined temperature (60). To 70 ° C.).
그러나, 종래 메탈 하이드라이드 탱크(T)는 엔진의 온도가 낮을때 즉, 초기시동시에는 메탈 하이드라이드 탱크(T)의 온도를 일정온도로 유지시킬 수 없으므로 수소의 공급압력이 매우 낮게 되고, 이로 인해 엔진의 구동이 불가능한 문제점이 지적되고 있다.However, the conventional metal hydride tank (T) when the engine temperature is low, that is, at the initial startup can not maintain the temperature of the metal hydride tank (T) at a constant temperature, the hydrogen supply pressure is very low, so Due to the problem that the engine can not be driven is pointed out.
본 발명은 상기 종래 메탈 하이드라이드 탱크가 가지는 문제점을 해소하기 위하여 안출한 것으로, 메탈 하이드라이드 탱크내의 온도가 일정온도 이하일 경우 일정온도로 상기 탱크내의 온도를 유지시켜 수소의공급압력을 증대시킴으로써, 냉간시동 및 초기시동의 원활성을 도모하기 위한 수소자동차의 메탈 하이드라이드 탱크 초기 가열장치를 제공하기 위한 것이다.The present invention has been made in order to solve the problems of the conventional metal hydride tank, if the temperature in the metal hydride tank is below a certain temperature by maintaining the temperature in the tank at a constant temperature to increase the supply pressure of hydrogen, cold It is to provide an initial heating device for a metal hydride tank of a hydrogen vehicle for the purpose of smooth starting and initial starting.
상기한 과제를 달성하기 위한 본 발명은 메탈 하이드라이드 탱크주위에 엔진의 냉각수를 순환시키는 것에 있어서, 상기 메탈 하이드라이드 탱크 내의 온도감지를 위한 온도센서와, 상기 온도센서의 감지온도가 일정온도 이하이면 엔진콘트롤 유니트의 제어신호에 의해 동작하는 릴레이와, 상기 릴레이 동작에 의해 전원이 공급되어 메탈 하이드라이드 탱크 내의 온도를 일정온도로 유지토록 하는 전기히터와로 구성됨을 특징으로 한다.The present invention for achieving the above object is to circulate the cooling water of the engine around the metal hydride tank, the temperature sensor for sensing the temperature in the metal hydride tank, and if the detected temperature of the temperature sensor is below a certain temperature And a relay operated by a control signal of the engine control unit, and an electric heater supplied with power by the relay operation to maintain the temperature in the metal hydride tank at a constant temperature.

이와 같은 본 발명을 도 2에 의하여 구체적으로 설명한다.This invention will be described in detail with reference to FIG. 2.
메탈 하이드라이드 탱크(T)의 주위에 엔진의 냉각수를 순환시키는 것에 있어서, 메탈 하이드라이드 탱크(T)내에 온도센서(1)를 내설하고, 온도센서(1)의 감지온도가 일정온도(60∼70℃)이하일 경우 엔진 콘트롤 유니트(2)가 이를 판단하여 릴레이(3)를 동작하도록 제어시킨다.In circulating the cooling water of the engine around the metal hydride tank (T), the temperature sensor (1) is built in the metal hydride tank (T), and the detected temperature of the temperature sensor (1) is a constant temperature (60 to 60). 70 ° C.) or less, the engine control unit 2 determines this and controls the relay 3 to operate.
즉, 릴레이(3)는 상기 엔진 콘트롤 유니트(2)와 연결되고, 그 일측은 전원 공급라인과 연결되도록 하며, 타측은 메탈 하이드라이드 탱크(T)내에 내설시킨 전기히터(4)에 연결시켜 구성하고 있다.That is, the relay 3 is connected to the engine control unit 2, one side of which is connected to the power supply line, the other side is configured by connecting to the electric heater (4) built in the metal hydride tank (T) Doing.
이와같이 구성된 본 발명의 작용효과는 다음과 같다.Effects of the present invention configured as described above are as follows.
통상적으로는 엔진 냉각수의 순환에 의해 메탈 하이드라이드 탱크(T)내의 온도는 60∼70℃의 일정온도로 유지되어 수소의 공급 압력을 증대시키게 되나, 냉간시동 또는 엔진의 초기 시동시에는 메탈 하이드라이드 탱크(T)내의 온도는 일정온도 이하로 떨어져 수소 공급 압력이 크게 저하되게 된다.Typically, the temperature in the metal hydride tank (T) is maintained at a constant temperature of 60 ~ 70 ℃ by the circulation of the engine coolant to increase the supply pressure of hydrogen, but during the cold start or the initial start of the engine metal hydride The temperature in the tank T falls below a certain temperature, and the hydrogen supply pressure greatly decreases.
이때, 메탈 하이드라이드 탱크(T)내에 내설시킨 온도센서(1)가 저하된 메탈 하이드라이드 탱크(T)내의 온도를 감지하면 엔진 콘트롤 유니트(2)에서 이를 판단하여 제어신호를 릴레이(3)에 인가한다. 이와 같이 제어신호를 받은 릴레이(3)는 전원공급라인과 전기히터(4) 사이의 차단된 전기적 회로를 연결시켜 전원이 메탈 하이드라이드 탱크(T)내의 전기히터(4)에 인가되어 가열되게 됨으로써 메탈 하이드라이드 탱크(T)내의 수소의 온도는 상승하게 되고, 이로인해 수소의 공급압력이 크게 증대되므로, 냉간 시동 및 초기 시동시 또는 일정온도 이하의 온도를 메탈 하이드라이드 탱크(T)가 가질때 수소를 원활히 공급할 수 있게 되어 엔진의 구동이 원활하게 이루어지는 점이다.At this time, when the temperature sensor 1 installed in the metal hydride tank T senses the temperature in the degraded metal hydride tank T, the engine control unit 2 determines this and transmits a control signal to the relay 3. Is authorized. The relay 3 receiving the control signal as described above connects the blocked electrical circuit between the power supply line and the electric heater 4 so that power is applied to the electric heater 4 in the metal hydride tank T to be heated. Since the temperature of hydrogen in the metal hydride tank (T) is increased, and thus the hydrogen supply pressure is greatly increased, the hydrogen at the time of cold start and initial start-up or when the metal hydride tank (T) has a temperature below a certain temperature It is possible to smoothly supply the point that the engine is running smoothly.
그리고, 가열히터(4)의 가열에 의해 메탈 하이드라이드 탱크(T)내의 온도가 일정온도로 유지되게 되면 엔진 콘트롤 유니트(2)에서 이를 판단하여 릴레이(3)를 동작케 함으로써 릴레이의 접점이 떨어져 전기히터(4)에 가해지는 전원공급을 차단시키게 된다.When the temperature in the metal hydride tank T is maintained at a constant temperature by heating the heating heater 4, the engine control unit 2 determines that the relay 3 is operated by operating the relay 3. The power supply to the electric heater 4 is cut off.
이상과 같이 본 발명은 수소를 연료로 사용하는 자동차의 메탈 하이드라이드 탱크내의 온도를 일정온도로 항상 유지시키도록 함으로써, 냉간시동 및 초기시동시에도 수소의 공급압력을 증대시켜 엔진의 구동을 원활하게 실행할 수 있는 특징이 있다.As described above, the present invention maintains the temperature in the metal hydride tank of a car using hydrogen as a fuel at a constant temperature at all times, thereby increasing the supply pressure of hydrogen even during cold start and initial start-up to smoothly drive the engine. There is a workable feature.
