본 발명은 전기자동차의 일종인 연료전지(Fuel Cell) 자동차에 관한 것으로, 더욱 상세하게는 자동차 냉방시스템에 사용되는 냉매의 유로를 조절하여 줌으로써 연료전지 자동차의 연료전지를 보다 효율적으로 냉각시킬 수 있는 연료전지 자동차의 열관리시스템에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a fuel cell vehicle, which is a type of electric vehicle. More particularly, the fuel cell of a fuel cell vehicle can be cooled more efficiently by adjusting a flow path of a refrigerant used in a vehicle cooling system. A thermal management system of a fuel cell vehicle.

근래에 들어 내연기관 자동차로부터 배출되는 배기가스로 인한 대기오염이 심각해지면서 배기가스를 배출하지 않는 전기자동차가 각광을 받고 있다. 이러한 전기자동차는 전기에너지를 사용하여 전동기를 회전시켜 줌으로써 주행되는 데, 연료전지 자동차는 전기에너지의 전원으로서 연료전지를 장착한 전기자동차를 말한다.In recent years, as the air pollution caused by the exhaust gas emitted from the internal combustion engine car has become serious, electric vehicles that do not emit exhaust gas are spotlighted. The electric vehicle is driven by rotating an electric motor using electric energy. A fuel cell vehicle refers to an electric vehicle equipped with a fuel cell as a power source of electric energy.

이와 같은 연료전지는 사용 중에 고열을 발생시키는 데, 그 수명과 성능을 유지하고, 가장 안정된 출력 상태를 얻기 위해서는 연료전지의 온도를 적정하게(예컨대, 고분자 전해질 연료전지의 경우는 약 80℃ 정도) 유지해야 한다. Such a fuel cell generates high heat during use, and in order to maintain its life and performance, and to obtain the most stable output state, the temperature of the fuel cell is appropriately adjusted (for example, about 80 ° C. in a polymer electrolyte fuel cell). It must be maintained.                         

종래의 연료전지 자동차의 열관리시스템으로서는 도 7에 도시된 바와 같은 것이 있다.A thermal management system of a conventional fuel cell vehicle is as shown in FIG.

상기 종래의 열관리시스템은 제1 순환펌프(44)에 의해 순환되는 제1 냉각유체를 사용하여 상기 연료전지(C)를 냉각시키는 제1 순환유로(41)와, 제2 순환펌프(43)에 의해 순환되는 제2 냉각유체에 의해 구동모터, 밧데리, 전기부품 등의 발열원을 냉각시키는 제2 순환유로(42)와, 상기 제1 순환유로(41) 내의 제1 냉각유체와 상기 제2 순환유로(42) 내의 제2 냉각유체와의 사이에서 열교환시키는 열교환기로 구성되어 있다. 즉, 응축기, 증발기를 경유하는 냉매유로(49)를 포함하여 구성된 냉방시스템은 단지 자동차 실내의 냉방에만 사용되고 있다.The conventional thermal management system includes a first circulation passage 41 and a second circulation pump 43 for cooling the fuel cell C using a first cooling fluid circulated by the first circulation pump 44. A second circulation passage 42 for cooling a heat source such as a drive motor, a battery, an electric component, and the like, and a first cooling fluid and the second circulation passage in the first circulation passage 41 by the second cooling fluid circulated by the second cooling fluid. It consists of a heat exchanger which heat-exchanges with the 2nd cooling fluid in (42). That is, the cooling system including the refrigerant passage 49 via the condenser and the evaporator is used only for cooling the interior of the automobile.

그런데, 연료전지에서 발생하는 방열량은 기존의 내연기관에 비해 동일 출력 기준으로 약 두 배가 많고, 냉각수의 온도는 오히려 약 40℃ 이상 낮기 때문에 방열기를 통해 외기로 열을 방출시키기 위해서는 방열기 크기와 냉각팬 용량을 상당히 크게 해야 한다. 특히, 외기온도가 높을 경우 방열기의 냉각수 온도와 그 방열기를 냉각시켜주는 외기온도의 차가 작기 때문에 방열을 증가시키기 위해서는 방열기 크기와 냉각팬 용량을 크게 해야 한다. 그러나, 이것은 전체적인 크기와 무게가 증가시키게 되고, 또한 장착공간의 제약으로 인하여 일정한 한계가 있는 문제점이 있었다.
However, the amount of heat dissipated in the fuel cell is about twice as high as that of the existing internal combustion engine, and the temperature of the coolant is about 40 ° C. or lower, so in order to dissipate heat to the outside air through the radiator, the size of the radiator and the cooling fan. The capacity must be quite large. In particular, when the outside temperature is high, the difference between the coolant temperature of the radiator and the outside temperature that cools the radiator is small, so the radiator size and the cooling fan capacity must be increased to increase the radiating heat. However, this increases the overall size and weight, and also there is a problem that there is a certain limitation due to the constraint of the mounting space.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 자동차 냉방시스템의 냉매를 활용하여 방열기와 냉각팬의 용량을 크게 해주지 않고서도 연료전지를 효율적으로 냉각시킬 수 있는 연료전지 자동차의 열관리시스템을 제공하는 것을 목적으로 한다.
