It is configured by installing two air discharge fan 57 each.

배터리 모듈(53)은 그 길이 방향이 배터리 트레이(51)의 폭 방향으로 설치되어 있다. 즉, 배터리 모듈(53)은 냉각 공기가 흐르는 방향과 수직하게 설치되어 있다.The longitudinal direction of the battery module 53 is provided in the width direction of the battery tray 51. That is, the battery module 53 is installed perpendicular to the direction in which cooling air flows.

도 1은 본 고안에 따른 전기자동차용 배터리 팩의 냉각 시스템의 구성도로서, 배터리 모듈(1)을 장착하는 배터리 트레이(3), 배터리 모듈(1)을 냉각시키는 공기를 공급 및 배출하는 공기 공급 및 배출 팬(5,7)을 포함하여 구성된다.1 is a configuration diagram of a cooling system of an electric vehicle battery pack according to the present invention, a battery tray 3 on which a battery module 1 is mounted, and an air supply for supplying and discharging air for cooling the battery module 1. And discharge fans 5, 7.

배터리 모듈(1)은 전기자동차에 동력원을 충분히 공급할 수 있도록 복수로 제공된다. 이 배터리 모듈(1)은 배터리 트레이(3) 상에서 전, 중, 후반부(9,11,13)의 3그룹으로 구분할 수 있도록 구획 배치된다. 특히 전, 중반부(9,11)의 배터리 모듈(1)은 공기 공급 팬(5)에서 공급되는 공기의 흐름 방향과 같은 배터리 트레이(3)의 길이 방향으로 설치되고, 후반부(13)의 배터리 모듈(1)은 배터리 트레이(3)의 폭 방향으로 설치되어 있다.The battery module 1 is provided in plurality so as to sufficiently supply a power source to the electric vehicle. The battery module 1 is partitioned on the battery tray 3 so as to be divided into three groups of front, middle, and second half parts 9, 11, 13. In particular, the battery modules 1 of the front and middle portions 9 and 11 are installed in the longitudinal direction of the battery tray 3, such as the flow direction of air supplied from the air supply fan 5, and the battery modules of the rear half 13. (1) is provided in the width direction of the battery tray 3.

배터리 트레이(3)는 전, 중, 후반부(9,11,13)의 배터리 모듈(1)을 장착할 수 있도록 구획되어 있고, 후반부(13)의 배터리 모듈(1)만을 냉각시키기 위한 별도의 냉각 공기 흡입 홀(15)을 후반부(13) 배터리 보듈(1)의 양측에 구비하고 있다.The battery tray 3 is partitioned so that the battery modules 1 of the front, middle, and second half parts 9, 11, 13 can be mounted, and separate cooling for cooling only the battery module 1 of the second half part 13. Air intake holes 15 are provided on both sides of the rear half 13 battery module 1.

공기 공급 팬(5)은 배터리 트레이(3)에 장착된 배터리 모듈(1)에 냉각 공기를 공급하도록 배터리 트레이(3)의 전방 양측에 각각 설치되어 있다.The air supply fan 5 is installed at both front sides of the battery tray 3 so as to supply cooling air to the battery module 1 mounted on the battery tray 3.

그리고 공기 배출 팬(7)은 공기 공급 팬(5)에 의하여 공급된 공기와 냉각 공기 흡입 홀(15)로 흡입되어 전, 중, 후반부(9,11,13)의 배터리 모듈(1)을 각각 냉각시킨 고온의 공기를 배출하도록 후반부(13) 상측 양쪽에 각각 2개씩 총 4개 설치되어 있다. 공기 배출 팬(7) 중, 2개는 종래와 같이 공기 공급 팬(5)에서 공급되는 공기의 배출을 담당하고, 나머지 2개는 냉각 공기 흡입 홀(15)로부터 흡입되는 공기의 배출을 담당한다.In addition, the air exhaust fan 7 is sucked into the air supplied by the air supply fan 5 and the cooling air intake hole 15 to discharge the battery modules 1 of the front, middle, and second half parts 9, 11, 13, respectively. A total of four are provided on each of the upper sides of the rear half 13 so as to discharge the cooled high-temperature air. Two of the air discharge fans 7 are responsible for the discharge of air supplied from the air supply fan 5 as in the prior art, and the other two are responsible for the discharge of the air sucked in from the cooling air intake hole 15. .

상술한 바와 같은 전기자동차용 배터리 팩의 냉각 시스템의 작용은 다음과 같다.The operation of the cooling system of the battery pack for an electric vehicle as described above is as follows.

배터리 모듈(1)에서 발생된 열은 공기 공급 팬(5)과 공기 배출 팬(7)의 공기 공급 및 배출에 따른 냉각 공기의 흐름에 의하여 냉각된다.The heat generated in the battery module 1 is cooled by the flow of cooling air according to the air supply and discharge of the air supply fan 5 and the air exhaust fan 7.

구체적으로 보면, 공기 공급 팬(5)에서 공급되는 저온의 공기는 배터리 트레이(3)에 길이 방향으로 설치된 전, 중반부(9,11)의 배터리 모듈(1)을 경유하면서 이들의 열을 흡수하여 배터리 모듈(1)을 냉각시키면서 고온의 공기로 변화되어 후반부(13)로 공급된다.Specifically, the low temperature air supplied from the air supply fan 5 absorbs heat while passing through the battery modules 1 of the front and middle portions 9 and 11 installed in the battery tray 3 in the longitudinal direction. Cooling the battery module 1 is converted into hot air and supplied to the second half 13.

이 후반부(13)로 공급되는 고온의 공기는 공기 배출 팬(7)에 의하여 외부로 배출된다. 이와 동시에 공기 배출 팬(7)의 배출력에 의하여 냉각 공기 흡입 홀(15)로 별도의 저온 공기가 흡입되어 후반부(11)의 배터리 모듈(1)만을 경유하면서 열을 흡수하여 후반부(11)의 배터리 모듈(1)을 냉각시키고 배출된다.The hot air supplied to the second half 13 is discharged to the outside by the air discharge fan 7. At the same time, a separate low temperature air is sucked into the cooling air intake hole 15 by the discharge force of the air discharge fan 7, and absorbs heat while passing through only the battery module 1 of the second half 11. The battery module 1 is cooled and discharged.

따라서 본 고안은 전, 중반부(9,11)와 후반부(13)의 배터리 모듈(1)을 각각 별도로 냉각시키므로 전, 후반부(9,13)의 배터리 모듈(1) 간의 온도 편차를 허용치 미만으로 낮출 수 있다.Therefore, the present invention cools the battery modules 1 of the front and middle parts 9 and 11 and the rear part 13 separately, thereby reducing the temperature deviation between the battery modules 1 of the front and second parts 9 and 13 to less than the allowable value. Can be.

본 고안의 전기자동차용 배터리 팩의 냉각 시스템은 전반부와 중반부의 배터리 모듈을 공기 흐름 방향으로 설치하고, 후반부의 배터리 모듈에 별도의 냉각 공기를 흡입하며, 후반부의 배터리 모듈에 공기 배출 팬을 4개 구비하므로 배터리 트레이에서 전, 후반부 배터리 모듈간의 온도 편차를 허용치 미만으로 낮추어 전력 공급 성능을 향상시킬 수 있다.The cooling system of the battery pack for an electric vehicle of the present invention installs the battery module in the first half and the middle half in the air flow direction, inhales the cooling air to the battery module in the second half, and has four air exhaust fans in the battery module in the second half. Since the battery tray lowers the temperature deviation between the front and rear battery modules to less than the allowable value, the power supply performance can be improved.
