Description

연료전지 자동차의 열교환기{Heat Exchanger of Fuel Cell Vehicle}Heat Exchanger of Fuel Cell Vehicle

본 발명은 연료전지 자동차의 열교환기에 관한 것으로, 더욱 상세하게는 열교환기의 탱크를 2개의 부분으로 양분하여 고온 냉각수와 저온 냉각수의 유로를 별도로 형성하여, 열교환기의 장착공간을 절약하고 방열성능을 향상시킬 수 있는 연료전지 자동차의 열교환기에 관한 것이다.The present invention relates to a heat exchanger of a fuel cell vehicle, and more particularly, by dividing the tank of the heat exchanger into two parts to form a flow path for the high temperature coolant and the low temperature coolant separately, thereby saving a mounting space of the heat exchanger and improving heat dissipation performance. A heat exchanger of a fuel cell vehicle that can be improved.

근래에 들어 내연기관 자동차로부터 배출되는 배기가스로 인한 대기오염 등이 심각해짐에 따라 배기가스를 배출하지 않는 전기자동차가 각광을 받고 있다. 이러한 전기자동차는 전기에너지로 구동되는 전동기의 회전에 의해 주행하게 되는 데, 연료전지 자동차는 전기에너지의 전원으로서 연료전지를 장착한 전기 자동차를 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. Such an electric vehicle is driven by the rotation of an electric motor driven by 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 사용됨에 따라 고열을 발생하므로, 그 수명과 성능을 유지하고, 가장 안정된 출력 상태를 얻기 위해서는 연료전지의 온도를 적정하게(예컨대, 고분자 전해질 연료전지의 경우는 약 80℃ 정도) 유지하는 것이 필요하다. 따라서, 연료전지의 효율을 극대화하기 위해서는, 냉각수로 방열된 열을 열교환기를 통해 외기로 방출하여야 한다.Since such fuel cells generate high heat as they are used, the temperature of the fuel cell is appropriately maintained (for example, about 80 ° C. in the case of a polymer electrolyte fuel cell) in order to maintain its life and performance and to obtain the most stable output state. It is necessary to maintain. Therefore, in order to maximize the efficiency of the fuel cell, the heat radiated with the cooling water must be discharged to the outside air through the heat exchanger.

한편, 구동모터나 전자부품 등의 발열원에서도 열이 발생하는 데, 상기 발열원을 적정온도로 작동시키기 위해서는 상기 연료전지용 열교환기 외에 별도의 열교환기가 필요하다. 이는, 연료전지의 작동온도와 상기 구동모터 등의 발열원의 작동온도가 서로 다르기 때문이다. 예컨대, 구동모터의 경우 작동온도가 대략 50℃ 정도이나, 연료전지의 경우는 작동온도가 대략 80℃ 정도이다. 따라서, 종래에는 도 1에 도시된 바와 같이, 자동차 전방부에 연료전지용 열교환기를 장착하고, 상대적으로 작동온도가 낮은 구동모터용 열교환기를 상기 연료전지용 열교환기 앞에 장착하였다. 그런데, 상기의 경우는 구동모터에 의해 외기온도가 상승하게 되고, 또한 풍량이 감소됨에 따라 연료전지용 열교환기의 방열 성능이 저하되는 문제점이 있었다. 그리고, 2개의 열교환기를 별도로 장착해야 하므로 장착공간에도 제약을 받는 문제점이 있었다.On the other hand, heat is also generated in a heat source such as a driving motor or an electronic component. In order to operate the heat source at an appropriate temperature, a heat exchanger other than the fuel cell heat exchanger is required. This is because the operating temperature of the fuel cell and the operating temperature of the heat generating source such as the driving motor are different from each other. For example, in the case of a drive motor, the operating temperature is about 50 ° C, but in the case of a fuel cell, the operating temperature is about 80 ° C. Therefore, conventionally, as shown in FIG. 1, a fuel cell heat exchanger is mounted on the front part of a vehicle, and a drive motor heat exchanger having a relatively low operating temperature is mounted in front of the fuel cell heat exchanger. However, in the above case, the outside air temperature is increased by the driving motor, and as the air volume is decreased, there is a problem in that the heat dissipation performance of the fuel cell heat exchanger is lowered. In addition, since the two heat exchangers must be separately installed, there is a problem in that the mounting space is restricted.

본 발명은 상기와 같은 문제점을 해결하기 위하여 안출된 것으로서, 열교환기의 탱크를 2개의 부분으로 양분하여 고온 냉각수와 저온 냉각수의 유로를 별도로 형성함으로써, 방열성능을 향상시킴과 동시에 열교환기의 장착공간을 절약할 수 있도록 하는 연료전지 자동차의 열교환기를 제공하는 것을 목적으로 한다.The present invention has been made in order to solve the above problems, by dividing the tank of the heat exchanger into two parts to form a separate channel of the high temperature coolant and the low temperature coolant, thereby improving heat dissipation performance and at the same time mounting space of the heat exchanger It is an object of the present invention to provide a heat exchanger of a fuel cell vehicle which can save fuel consumption.

이하, 본 발명의 실시예를 도면을 참조하여 상세히 설명한다.Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

도 2에는 본 발명에 따른 연료전지 자동차의 열교환기의 제1 실시예인 다운 플로우 형식(Down Flow Type)의 열교환기의 주요 구성요소가 도시되어 있다.FIG. 2 shows the main components of a down flow type heat exchanger, which is a first embodiment of a heat exchanger of a fuel cell vehicle according to the present invention.

상기 제1 실시예에서, 복수의 튜브(6)는 그 양단이 제1 탱크(1)와 제2 탱크(2)에 각각 연결되어 있으며, 상기 복수의 튜브(6) 사이에는 복수의 주름핀(7)이 장착되어 있다. 그리고, 상기 제1 탱크(1)와 제2 탱크(2)는 그 내부에 장착된 배플(8)에 의하여 각각 구동모터를 포함한 발열원용 탱크(1a, 2a)와 연료전지용 탱크(1b, 2b)로 나뉜다. 한편, 상기 제1 및 제2 탱크에는 냉각수 유입구(9, 3)와 냉각수 유출구(4, 5)가 각각 형성되어 있다.In the first embodiment, the plurality of tubes 6 are connected at both ends to the first tank 1 and the second tank 2, respectively, and a plurality of corrugated pins (between the plurality of tubes 6). 7) is fitted. In addition, the first tank 1 and the second tank 2 are tanks 1a and 2a for a heat source including a driving motor and tanks 1b and 2b, respectively, by a baffle 8 mounted therein. Divided into Meanwhile, the coolant inlets 9 and 3 and the coolant outlets 4 and 5 are formed in the first and second tanks, respectively.

상기 제1 실시예의 작용을 설명하면 다음과 같다.Referring to the operation of the first embodiment as follows.

구동모터 등의 발열원을 경유하면서 열을 흡수한 냉각수는 상기 냉각수 유입구 9를 통하여 발열원용 탱크 1a로 유입된 후, 상기 튜브(6)를 따라 흐르면서 상기주름핀(7)을 통하여 외부 공기와 열교환하여 냉각되어 냉각수 유출구 4를 통하여 발열원용 탱크 2a를 빠져나간다.Cooling water that absorbs heat via a heat source such as a driving motor flows into the heat generating tank 1a through the cooling water inlet 9 and then flows along the tube 6 to exchange heat with outside air through the pins 7. It cools and exits the heat generating tank 2a through the cooling water outlet 4.

한편, 연료전지를 경유하면서 열을 흡수한 냉각수는 상기 냉각수 유입구 3을 통하여 연료전지용 탱크 1b로 유입된 후, 상기 튜브(6)를 따라 흐르면서 상기 주름핀(7)을 통하여 외부 공기와 열교환하여 냉각되어 냉각수 유출구 5를 통하여 연료전지용 탱크 2b를 빠져나간다.Meanwhile, the coolant absorbing heat while passing through the fuel cell flows into the fuel cell tank 1b through the coolant inlet 3 and then flows along the tube 6 to exchange heat with external air through the corrugated fins 7 to cool it. And exits the fuel cell tank 2b through the coolant outlet 5.

따라서, 구동모터 등의 발열원을 경유하면서 열을 흡수한 냉각수와, 연료전지를 경유하면서 열을 흡수한 냉각수의 흐름은 상기 제1 및 제2 탱크에 장착된 배플(8)에 의해 섞이지 않고 분리된 상태를 유지하면서 열교환기를 빠져나가게 된다.Therefore, the flow of the cooling water absorbing heat via a heat source such as a drive motor and the cooling water absorbing heat via a fuel cell are separated without mixing by the baffles 8 mounted to the first and second tanks. It exits the heat exchanger while maintaining the state.

도 3에는 본 발명에 따른 연료전지 자동차의 열교환기의 제2 실시예인 크로스 플로우 형식(Cross Flow Type)의 열교환기의 주요 구성요소가 도시되어 있다.3 shows the main components of a cross flow type heat exchanger, which is a second embodiment of the heat exchanger of a fuel cell vehicle according to the present invention.

상기 제2 실시예는 냉각수의 흐름이 수평방향으로 되어 있다는 점을 제외하고는, 주요 구성요소 및 그 작용이 상기 제1 실시예와 동일하다.The second embodiment is the same as that of the first embodiment, except that the flow of the cooling water is in the horizontal direction, and the main components and their functions.

도 4에는 본 발명에 따른 크로스 플로우 형식의 열교환기의 또 다른 실시예(제3 실시예)가 도시되어 있다.Figure 4 shows another embodiment (third embodiment) of a cross flow type heat exchanger according to the present invention.

한 쌍의 리턴탱크(19, 19)가 복수의 튜브(16)를 가로질러 설치된 점을 제외하고는 상기 제2 실시예와 주요 구성요소가 동일하다.The main components are the same as those of the second embodiment except that a pair of return tanks 19, 19 are installed across the plurality of tubes 16.

상기 제3 실시예의 작용을 설명하면 다음과 같다.The operation of the third embodiment is as follows.

구동모터, 전자부품, 밧데리 등의 발열원을 경유하면서 상기 발열원으로부터 열을 흡수한 냉각수는, 상기 냉각수 유입구 12를 통하여 탱크 11a로 유입된다. 유입된 상기 냉각수는 상기 튜브(16)를 따라 흐르면서 상기 주름핀(17)을 통하여 외기와 열교환하여 냉각되면서 리턴탱크(19)에 다다른다. 그 다음, 상기 리턴탱크(19)을 통하여 하방향으로 경로를 바꾼 후, 상기 튜브(16)를 따라 흐르면서 냉각수 유출구 13를 통하여 탱크 12a를 빠져나간다.Cooling water that absorbs heat from the heat generating source while passing through a heat generating source such as a drive motor, an electronic component, or a battery, flows into the tank 11a through the cooling water inlet 12. The introduced coolant flows along the tube 16 to cool down by exchanging heat with the outside air through the corrugated fin 17 to reach the return tank 19. Then, after changing the path downward through the return tank 19, it flows along the tube 16 and exits the tank 12a through the coolant outlet 13.

한편, 연료전지를 경유하면서 열을 흡수한 냉각수는, 상기 냉각수 유입구 14를 통하여 탱크 11b로 유입된다. 유입된 상기 냉각수는 상기 튜브(16)를 따라 흐르면서 상기 주름핀(17)을 통하여 외기와 열교환하여 냉각되면서 리턴탱크(19)에 다다른다. 그 다음, 상기 리턴탱크(19)을 통하여 하방향으로 경로를 바꾼 후, 상기 튜브(16)를 따라 흐르면서 냉각수 유출구 15를 통하여 탱크 12b를 빠져나간다.On the other hand, the coolant absorbing heat via the fuel cell flows into the tank 11b through the coolant inlet 14. The introduced coolant flows along the tube 16 to cool down by exchanging heat with the outside air through the corrugated fin 17 to reach the return tank 19. Then, after changing the path downward through the return tank 19, it flows along the tube 16 and exits the tank 12b through the coolant outlet 15.

상기와 같은 구성을 가지는 본 발명은, 종래의 2개의 열교환기가 일체화되어 있기 때문에 자동차에 장착시 그 장착공간을 콤팩트(compact)하게 할 수 있는 동시에 이로 인한 작업공수를 줄일 수 있으며, 또한 종래에 구동모터 등의 발열원용 열교환기가 연료전지용 열교환기의 전방에 설치됨으로 인해 연료전지 열교환기의 방열성능이 저하되는 것을 방지할 수 있는 효과를 가진다.According to the present invention having the above-described configuration, since two conventional heat exchangers are integrated, the mounting space can be made compact when the vehicle is mounted on a vehicle, and at the same time, the work man-hours can be reduced. Since a heat exchanger for a heat source such as a motor is installed in front of the fuel cell heat exchanger, the heat dissipation performance of the fuel cell heat exchanger may be prevented from being lowered.
