Description

하이브리드 차량용 배터리 냉각 장치{Device for cooling battery of HEV}Hybrid vehicle battery cooling device {Device for cooling battery of HEV}

본 발명은 하이브리드 차량용 배터리 냉각 장치에 관한 것으로서, 더욱 상세하게는 부채꼴 타입의 배터리케이스내에 다수의 배터리를 부채꼴 타입으로 배열하여, 최대의 공기 풍량으로 각 배터리를 고르게 냉각시킬 수 있도록 함으로써, 배터리의 냉각 성능을 향상시킬 수 있도록 한 하이브리드 차량용 배터리 냉각 장치에 관한 것이다.The present invention relates to a battery cooling device for a hybrid vehicle, and more particularly, by arranging a plurality of batteries in a fan-shaped battery case in a fan-shaped battery case to cool each battery evenly with the maximum air volume. The present invention relates to a battery cooling device for a hybrid vehicle capable of improving performance.

하이브리드 차량은 엔진 뿐만 아니라 모터 구동원을 보조 동력원으로 채택하여, 배기가스 저감 및 연비 향상을 도모할 수 있는 미래형 차량으로서, 모터의 동작을 위한 에너지원인 고전압배터리가 인버터를 통해 모터와 충방전 가능하게 연결되어 있다.The hybrid vehicle is a futuristic vehicle that adopts not only an engine but also a motor driving source as an auxiliary power source to reduce exhaust gas and improve fuel efficiency, and a high voltage battery, which is an energy source for the operation of the motor, is connected to the motor through an inverter so that it can be charged and discharged. It is.

하이브리드 차량에 탑재되는 배터리중 파우치 타입의 배터리는 얇은 판형의 구조로 몇 장을 셀을 하나로 묶어 모듈화시켜 사용하게 되는데, 하이브리드 차량의 사양에 따라 모듈을 직렬로 연결하여 패키지를 구성하고 있다.Pouch-type battery among the batteries installed in the hybrid vehicle has a thin plate structure, and several sheets are used by modularizing the cells. The package is formed by connecting the modules in series according to the specification of the hybrid vehicle.

이렇게 직렬로 연결된 배터리 모듈 패키지는 그 충방전시 배터리 셀에서 발열하는 현상이 발생되며, 각 배터리 셀의 온도는 냉각특성에 따라 셀 별로 다르게 나타나기도 하고, 셀의 온도에 따라 충방전 전력이 달라지지만, 배터리 셀은 25~40℃ 범위의 적정 작동온도에서 운전이 되어야 한다.In this case, the battery module package connected in series generates heat from the battery cells during charge / discharge. The temperature of each battery cell may be different for each cell depending on the cooling characteristics, and the charge / discharge power varies depending on the temperature of the cell. The battery cell should be operated at an appropriate operating temperature in the range of 25 to 40 ° C.

종래의 배터리 냉각 장치는 강제 대류 열전달 방식의 냉각 구조로서, 도 4에 도시된 바와 같이 일측 상단에 공기유입구(2)가 형성되고, 타측에는 블로워(3)가 장착된 직사각체의 배터리케이스(1)내에 배터리 셀(4)들이 일렬로 배열되어 있으며, 배터리케이스(1)의 바닥면쪽에는 블로워(3)를 향하는 공기통로(5)가 형성되어 있다.Conventional battery cooling device is a cooling structure of the forced convection heat transfer method, as shown in Figure 4, the air inlet (2) is formed at the upper end of one side, the other side of the rectangular battery case (1) is equipped with a blower (3) The battery cells 4 are arranged in a line, and an air passage 5 toward the blower 3 is formed at the bottom surface of the battery case 1.

따라서, 상기 블로워(3)의 구동과 함께 배터리케이스(1)의 공기유입구(2)를 통해 공기가 흡입되며 유입되어 배터리 셀(4)을 냉각시킨 후, 블로워(3)를 통해 빠져나가게 된다.Therefore, the air is sucked in through the air inlet 2 of the battery case 1 together with the driving of the blower 3 to cool the battery cell 4, and then exits through the blower 3.

즉, 배터리케이스(1)내로 공기가 강제 유입될 때, 냉각공기의 유선이 형성됨에 따라, 유입되는 차가운 냉각공기는 각 배터리 셀(4) 사이의 갭(Gap)으로 통과하면서 셀(4)의 열량을 빼앗아 배터리케이스(1)의 바닥쪽에 형성된 하부 공기통로(5)로 이동한 후, 블로워(3)를 거쳐 외부로 배출된다.That is, when air is forced into the battery case 1, as a stream of cooling air is formed, the incoming cold cooling air passes through the gap Gap between the respective battery cells 4, and thus, of the cell 4. The heat is taken away and moved to the lower air passage 5 formed at the bottom of the battery case 1, and then discharged to the outside through the blower (3).

그러나, 상기와 같은 종래의 배터리 냉각 구조를 다음과 같은 단점이 있었다.However, the conventional battery cooling structure as described above has the following disadvantages.

배터리 모듈(module) 개수는 그 적용차종에 따라 승용차종은 6개의 모듈 또는 9개의 모듈을 적용하고, 버스와 같은 상용차종은 12개의 모듈을 채택하고 있으 며, 1개의 모듈당 4장의 배터리 셀 묶음으로 구성되고, 각 셀묶음은 2개의 셀로 구성되어 있는 바, 승용에 비해 상용 차량의 배터리 모듈개수 증가로 가로방향의 길이가 증가되고, 각 배터리 냉각유로로 냉각공기를 균등하게 분배하는데 어려움이 있다.The number of battery modules is 6 or 9 modules for passenger cars, and 12 modules are used for commercial vehicles such as buses. Each cell bundle is composed of two cells, and the length of the horizontal direction is increased by increasing the number of battery modules of a commercial vehicle compared to a passenger vehicle, and it is difficult to distribute cooling air evenly to each battery cooling channel.

특히, 종래의 배터리케이스에는 상기와 같이 배터리 위쪽에 공기유입구가 형성되고, 배터리 아래쪽에 하부통로가 형성되며, 공기유입구의 반대쪽에 블로워가 형성된 Z 타입 유로구조를 이루기 때문에 배터리에 대한 균등한 온도분포 확보에 어려움이 있었다.Particularly, in the conventional battery case, the air inlet is formed above the battery, the lower passage is formed below the battery, and the Z-type flow path structure is formed on the opposite side of the air inlet so that the temperature distribution is uniform for the battery. There was a difficulty in securing.

즉, 블로워를 가동시켜 외부공기를 배터리케이스 내부로 유입시킨 후, 배터리 내부 온도조건을 살펴본 실험 결과, 첨부한 도 5에 도시된 바와 같이 배터리케이스내로 유입된 냉각공기의 유동 속도 분포가 배터리케이스의 길이방향을 따라 편차가 발생함을 알 수 있었고, 또한 첨부한 도 6에 도시된 바와 같이 냉각공기 및 각 배터리 셀간의 온도분포도 편차가 발생함을 알 수 있었으며, 이와 같이 종래의 배터리 냉각 구조로는 냉각공기의 유동을 고르게 분포시킬 수 없고, 또한 각 배터리 셀을 고르게 냉각할 수 없는 단점이 있었다.That is, after the blower is operated to introduce external air into the battery case, and as a result of experiments examining the internal temperature conditions of the battery, the flow rate distribution of the cooling air introduced into the battery case is shown in FIG. It can be seen that the deviation occurs along the longitudinal direction, and also shown that the temperature distribution between the cooling air and each battery cell occurs as shown in the accompanying Figure 6, as described above, There was a disadvantage in that the flow of cooling air was not evenly distributed, and that each battery cell could not be evenly cooled.

본 발명은 상기와 같은 점을 감안하여 안출한 것으로서, 배터리케이스를 부채꼴 형상으로 형성하고, 이 부채꼴 타입의 배터리케이스내에 다수의 배터리를 부 채꼴 타입으로 균등 배열하여, 부채꼴 타입의 배터리케이스의 외측으로부터 유입된 냉각공기가 반경방향을 향하는 동시에 각 배터리 셀을 통과하여, 중심부에 연결된 팬을 통과하여 패키지 외측으로 배출되도록 함으로써, 최대의 공기 풍량으로 각 배터리 셀을 고르게 냉각시켜 배터리 냉각 성능을 크게 향상시킬 수 있도록 한 하이브리드 차량용 배터리 냉각 장치를 제공하는데 그 목적이 있다.The present invention has been made in view of the above, and the battery case is formed into a fan shape, and in this fan type battery case, a plurality of batteries are equally arranged in a fan shape type, and from the outside of the fan type battery case. Inflow of cooling air is radially and simultaneously passes through each battery cell, through a fan connected to the center, and discharged out of the package, thereby evenly cooling each battery cell with the maximum amount of air flow, thereby greatly improving battery cooling performance. It is an object of the present invention to provide a battery cooling device for a hybrid vehicle.

상기한 목적을 달성하기 위한 본 발명은 소정의 두께 및 내체적을 갖는 부채꼴 형상의 배터리 케이스와; 상기 부채꼴 형상을 갖는 배터리 케이스의 외주면에 등간격을 이루며 형성되는 공기유입구와; 상기 부채꼴 형상을 갖는 배터리 케이스의 수평면 중심부에 형성된 공기배출구와; 상기 공기배출구에 장착되는 블로워; 상기 배터리케이스내에 부채꼴 배열을 이루며 균등 배열된 다수의 배터리 셀; 을 포함하여 구성된 것을 특징으로 하는 하이브리드 차량용 배터리 냉각 장치를 제공한다.The present invention for achieving the above object is a fan-shaped battery case having a predetermined thickness and internal volume; An air inlet formed at equal intervals on an outer circumferential surface of the battery case having the fan shape; An air outlet formed at a center of a horizontal surface of the battery case having the fan shape; A blower mounted to the air outlet; A plurality of battery cells arranged uniformly in a fan shape in the battery case; It provides a hybrid vehicle battery cooling device comprising a.

바람직한 일 구현예로서, 상기 다수의 배터리 셀간의 간격은 등간격으로 형성되는 동시에 공기유입구쪽에서 공구배출구쪽을 향하면서 점차 좁아지는 공기통로를 형성하는 것을 특징으로 한다.In a preferred embodiment, the interval between the plurality of battery cells is formed at equal intervals and at the same time characterized in that the air inlet toward the tool outlet toward the narrower gradually forming the air passage.

상기한 과제 해결 수단을 통하여, 본 발명은 다음과 같은 효과를 제공한다.Through the above problem solving means, the present invention provides the following effects.

본 발명에 따르면, 배터리케이스를 부채꼴 형상으로 형성하고, 이 부채꼴 타입의 배터리케이스내에 다수의 배터리를 부채꼴 타입으로 균등 배열하여, 냉각공기가 각 배터리 셀 사이로 통과하도록 함으로써, 최대의 공기 풍량으로 각 배터리를 고르게 냉각시킬 수 있어 배터리의 냉각 성능을 크게 향상시킬 수 있다.According to the present invention, the battery case is formed in a fan shape, and a plurality of batteries are evenly arranged in a fan shape in this fan type battery case, so that the cooling air passes between each battery cell, thereby allowing each battery to have a maximum amount of air flow. Cooling evenly can greatly improve the cooling performance of the battery.

특히, 각 배터리 셀 사이로 공기가 유입될 때, 그리고 각 배터리 셀 사이로 공기가 빠져나갈 때, 공기의 유동방향이 굴절되지 않으므로 유동압에 의한 풍량 손실을 최소화시킬 수 있고, 유동압에 의한 손실이 적음에 따라 블로워의 팬에 걸리는 부하가 적어지므로 최대의 풍량을 얻을 수 있어 배터리 냉각 성능을 극대화시킬 수 있다.In particular, when air flows in between each battery cell and when air flows out between each battery cell, the flow direction of the air is not refracted, thereby minimizing air flow loss due to the flow pressure, and the loss due to the flow pressure is small. This reduces the load on the blower's fan, allowing maximum airflow to maximize battery cooling performance.

또한, 배터리 셀의 배치 형태가 균일하여, 외기가 유입되어 배출되는 형태가 각 배터리 셀에 동일하게 작용됨에 따라, 배터리 셀간의 온도편차를 최소화할 수 있다.In addition, since the arrangement of the battery cells is uniform, the form in which outside air is introduced and discharged acts on each battery cell in the same manner, thereby minimizing a temperature deviation between the battery cells.

이하, 본 발명의 바람직한 실시예를 첨부도면을 참조로 상세하게 설명하기로 한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

본 발명에 따른 배터리 냉각 장치는 공기냉각식 냉각 방식을 채택한 것으로서, 배터리케이스를 부채꼴 형상으로 형성하고, 그 내부에 다수의 배터리 셀들도 부채꼴 모양으로 배치하여, 냉각공기는 부채꼴 외측으로부터 유입되어 반경방향을 향하며 각 배터리 셀을 통과한 후, 배터리 케이스의 중앙부에 연결된 팬을 통과하여 외부로 배출되는 구조로 구비된다.The battery cooling apparatus according to the present invention adopts an air-cooled cooling method, and forms a battery case in a fan shape, and arranges a plurality of battery cells therein in a fan shape, so that cooling air flows in from the outside of the fan shape in a radial direction. After passing through each of the battery cells, and passing through the fan connected to the center portion of the battery case is provided with a structure that is discharged to the outside.

보다 상세하게는, 본 발명의 배터리 케이스는 소정의 두께 및 내체적을 갖는 부채꼴 형상으로 제작되고, 부채꼴 형상을 갖는 배터리 케이스(10)의 외주면을 따라 공기유입구(12)가 등간격으로 형성되며, 부채꼴 형상을 갖는 배터리 케이스(10)의 수평면 중심부에는 블로워(16)가 구동 가능하게 장착되는 공기배출구(14)가 형성된 구조로 구비된다.In more detail, the battery case of the present invention is manufactured in a fan shape having a predetermined thickness and internal volume, and the air inlets 12 are formed at equal intervals along the outer circumferential surface of the battery case 10 having a fan shape. The central portion of the horizontal surface of the battery case 10 having a fan shape is provided with a structure in which an air outlet 14 to which the blower 16 is driven is formed.

이때, 상기 배터리케이스(10)내에 배열되는 다수의 배터리 셀(18)들도 부채꼴 배열을 이루며 균등하게 배치되는 바, 각 배터리 셀(18)의 선단부와 배터리케이스(10)의 공기유입구(12)간의 거리가 동일하도록 배치하고, 공기배출구(14)는 부채꼴 모양의 중심부 즉, 배터리 케이스의 수평면에서 그 중심부에 형성하여 배터리 셀을 통과한 공기가 합류되도록 한다.In this case, the plurality of battery cells 18 arranged in the battery case 10 are also arranged evenly in a fan-shaped arrangement, the front end of each battery cell 18 and the air inlet 12 of the battery case 10 The distance between the same is arranged, the air outlet 14 is formed in the center of the fan-shaped center, that is, in the horizontal plane of the battery case so that the air passing through the battery cell is joined.

특히, 상기 다수의 배터리 셀(18)간의 간격은 등간격으로 배열되되, 공기유입구(12)쪽에서 공구배출구(14)쪽을 향하면서 점차 좁아지는 공기통로(20)가 형성되도록 한다.In particular, the interval between the plurality of battery cells 18 are arranged at equal intervals, so that the air passage 20 gradually narrowing toward the tool outlet 14 from the air inlet 12 side.

따라서, 상기 블로워(16)를 구동시킴에 따라, 배터리케이스(10)의 공기유입구(12)를 통해 외부공기가 유입된 후, 각 배터리 셀(18)의 사이 즉, 공기통로(20) 를 통과한 다음, 공기배출구(14)로 빠져나가게 되는데, 유입된 공기가 각 공기통로(20)에 고르게 분배되며 통과하기 때문에 최대의 공기 풍량으로 각 배터리를 고르게 냉각시킬 수 있다.Accordingly, as the blower 16 is driven, external air flows in through the air inlet 12 of the battery case 10, and then passes through the air passage 20 between the battery cells 18. Then, the air is discharged to the outlet 14, since the introduced air is evenly distributed and passed through each air passage 20, it is possible to cool each battery evenly with the maximum air volume.

특히, 첨부한 도 3에 도시된 바와 같이 각 배터리 셀(18) 사이인 공기통로(20)로 공기가 최초 유입될 때, 그리고 각 배터리 셀(18) 사이로 공기가 빠져나갈 때, 공기의 유동방향이 굴절되지 않고 직선을 이루게 되므로, 공기 유동압에 의한 풍량 손실을 최소화시킬 수 있고, 또한 공기 유동압에 의한 손실이 적음에 따라 블로워의 팬에 걸리는 부하가 적어지므로, 결국 최대의 풍량으로 각 배터리 셀들을 고르게 냉각시킬 수 있다.In particular, when air first enters the air passage 20 between each of the battery cells 18, and when air escapes between the respective battery cells 18, as shown in FIG. Since the straight line is not refracted, the loss of air flow due to the air flow pressure can be minimized, and the load on the fan of the blower becomes less as the loss due to the air flow pressure is small, so that each battery at the maximum air flow rate is eventually used. The cells can be cooled evenly.

또한, 상기 각 배터리 셀(18)의 배치 형태가 부채꼴을 이루며 균일하게 배열된 상태이므로, 외기가 유입된 후, 배출되는 동작이 각 배터리 셀에 동일하게 작용됨에 따라, 배터리 셀간의 온도편차를 최소화시킬 수 있다.In addition, since the arrangement of the battery cells 18 is a fan-shaped and uniformly arranged state, the operation of discharging after the outside air is applied to each battery cell is the same, thereby minimizing the temperature deviation between the battery cells. You can.
