본 발명은 배터리 모듈 냉각용 지지장치에 관한 것으로서, 더욱 상세하게는 복수의 배터리 모듈(이하, 모듈이라고함)을 냉각할 때 냉각풍의 흐름을 흐뜨리지 않는 정류핀을 설치하고, 모든 모듈 온도를 간단한 구조로 조정하여 온도차이를 규정치 내로 유지함으로써, 모듈의 수명을 연장시키고 부품비를 삭감할 수 있도록 한 배터리 모듈 냉각용 지지장치에 관한 것이다.The present invention relates to a support for cooling a battery module, and more particularly, to install a rectifying pin that does not disturb the flow of cooling air when cooling a plurality of battery modules (hereinafter referred to as modules), and to simplify all module temperatures The present invention relates to a battery module cooling support device, which is configured to adjust the structure to maintain a temperature difference within a specified value, thereby extending the life of the module and reducing the component cost.

일반적으로 자동차의 배터리는 자동차의 각 요소에 대한 전력공급 부품으로서 차량의 전기 부하와 발전부에 의하여 충방전을 반복하게 된다. In general, a battery of a vehicle is a power supply component for each element of the vehicle and repeats charging and discharging by the electric load and the power generation unit of the vehicle.

이러한 과정 중 배터리의 온도 상승은 배터리 내부 저항의 변화를 가져오게 되고 전기적인 성능이 저하되며, 차량의 효율적인 전기 관리가 이루어지지 못하는 문제를 가져온다. The temperature rise of the battery during this process causes a change in the internal resistance of the battery, the electrical performance is degraded, and the problem is that the efficient electrical management of the vehicle is not achieved.

특히 최근의 하이브리드 자동차의 2차 배터리의 개발 및 적용의 일반화에 따라 배터리의 내부 온도를 적정 수준으로 냉각시켜야 할 현실적 필요성이 더욱 대두하게 되었다.In particular, with the recent development and application of secondary batteries for hybrid vehicles, the practical necessity of cooling the internal temperature of the battery to an appropriate level has increased.

한편, 상기 배터리 모듈의 냉각과 관련한 종래기술로서, 일본특허공개 평09-086188(도 1) 및 평10-255859(도 2 내지 도 4)에 있어서 모듈(1,2)의 냉각온도를 규정치내로 유지하기 위해 모듈 주위에 정류 핀(15,72)을 설치하는 구조가 개시되어 있다. On the other hand, in the prior art related to the cooling of the battery module, the cooling temperature of the module (1, 2) in Japanese Patent Application Laid-Open No. 09-086188 (Fig. 1) and No. 10-255859 (Fig. 2 to Fig. 4) within a prescribed value. A structure is disclosed in which rectifying pins 15 and 72 are provided around the module for retention.

그러나 이러한 구조는 각 모듈에 냉각풍이 송풍되는 양을 변화시키고 모듈 온도를 조정하는 효과가 있으나, 냉각풍의 흐름을 크게 흩뜨려(도 5의 모듈A열), 냉각풍의 압손(壓損)이 증대되어 냉각효과를 저하시키는 원인이 된다. However, such a structure has an effect of changing the amount of cooling air blown to each module and adjusting the module temperature, but greatly disperses the flow of cooling air (Module A in FIG. 5), thereby increasing the pressure loss of the cooling air. It causes a decrease in the cooling effect.

따라서 상기 모듈에 보다 많은 풍량을 공급하는 냉각 핀을 설치할 필요가 있어 부품비의 증가 요인이 되고 있다.Therefore, it is necessary to provide a cooling fin for supplying more air volume to the module, which is an increase factor of the component cost.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 복수의 모듈을 냉각할 때 냉각풍의 흐름을 흐뜨리지 않는 정류핀을 설치하고, 모든 모듈 온도를 간단한 구조로 조정하여 온도차이를 규정치 내로 유지함으로써, 모듈의 수명을 연장시키고 부품비를 삭감할 수 있도록 한 배터리 모듈 냉각용 지지장치를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, by installing a rectifying pin that does not disturb the flow of cooling air when cooling a plurality of modules, by adjusting the temperature of all modules in a simple structure to maintain the temperature difference within the prescribed value It is an object of the present invention to provide a support for cooling a battery module that can extend the life of the module and reduce the component cost.

상기한 목적을 달성하기 위한 본 발명은 복수의 배터리 모듈(102)을 냉각하기 위해 양측면에 흡기구(101)와 배기구가 형성된 케이스(100)와, 상기 흡기구(101)를 통해 유입된 냉각풍이 원활하게 유동하도록 상기 케이스(100)에 수납된 이웃하는 모듈(102) 사이의 빈 공간에 설치된 정류핀을 포함하는 배터리 모듈 냉각용 지지장치에 있어서, 상기 정류핀의 양측면은 냉각풍의 흐름방향을 기준으로 상하방향으로 모듈(102)의 원주면에 대응되도록 오목하게 형성되고, 상기 정류핀의 상하면은 상기 냉각풍이 원활하게 이동하도록 곡면으로 오목하게 형성된 것을 특징으로 하는 배터리 모듈 냉각용 지지장치를 제공한다.In order to achieve the above object, the present invention provides a case 100 having both an inlet port 101 and an exhaust port formed on both sides thereof to cool the plurality of battery modules 102, and cooling air introduced through the inlet port 101 smoothly. In the battery module cooling support device including a rectifying pin installed in the empty space between neighboring modules 102 accommodated in the case 100 to flow, both sides of the rectifying pin up and down based on the flow direction of the cooling wind It is formed to be concave to correspond to the circumferential surface of the module 102 in the direction, and the upper and lower surfaces of the rectifying pin provides a support for cooling the battery module, characterized in that formed in a concave curved surface to move the cooling wind smoothly.

Temperature uniformity may be performed to extend module 102 life.

또한 흡기에서 배출까지의 공기저항이 전체적으로 저감되므로 최소한의 냉각풍 공급으로 소정의 냉각성능을 얻을 수 있게 된다.  In addition, since the air resistance from intake to discharge is reduced as a whole, it is possible to obtain a predetermined cooling performance with minimal cooling wind supply.

따라서 종래에 비해 소형 냉각팬(fan)을 사용할 수 있게 되고 부품비 삭감, 팬 소비전력, 팬 소음 및 팬 진동 저감에도 기여할 수 있다. Therefore, it is possible to use a small cooling fan (fan) compared to the prior art and can contribute to the reduction of component cost, fan power consumption, fan noise and fan vibration.

Will move smoothly.

도 6의 왼쪽에서 두번째 및 세번째 정류핀은 형상을 달리 하여 예시한 것이다. 즉, 얇은 판을 원형 곡면으로 형성한 것(120), 사다리꼴 모양을 하되 하부면이 원형의 곡면을 형성한 것(130) 및 삼각형(140) 또는 사각형(150) 등을 포함하여, 냉각풍이 모듈(102) 사이에서 원활하게 이동할 수 있는 형상이면 어떠한 형태로든 가능하다.The second and third rectifying pins in the left side of Figure 6 are illustrated with different shapes. That is, the thin plate is formed in a circular curved surface (120), the trapezoidal shape, but the lower surface is a circular curved surface (130), including a triangle 140 or a square 150, the cooling wind module Any shape may be used as long as it can be moved smoothly between the 102.
