Description

능동형 실내외 냉각공기 복합 유동제어 방식의 배터리공조장치Active indoor / outdoor cooling air combined flow control type battery air conditioner
본 발명은 배터리공조장치에 관한 것으로서, 자동차 배터리에서 발생하는 열을 배출하고 배터리를 냉각시키기 위해서 자동차 외부의 공기와 자동차 실내의 공기를 이용하여 배터리팩을 냉각시키는 기능을 가지고 있는 능동형 실내외 냉각공기 복합 유동제어 방식의 배터리공조장치에 관한 것이다.The present invention relates to a battery air conditioner, and more particularly, to an active indoor / outdoor cooling-air hybrid vehicle having a function of cooling a battery pack using air outside the automobile and air in the automobile to discharge heat generated from the automotive battery and cool the battery To a battery air conditioner of a flow control type.
최근 자동차업계는 석유에너지를 사용하지 않는 전기자동차 또는 석유에너지와 전기에너지를 적절히 겸용하여 사용하여 주행하는 하이브리드 자동차를 개발하고 제조하는 데에 심혈을 기울이고 있다. 여기서, 전기자동차에는 대용량의 배터리가 장착되는데, 이러한 배터리는 온도에 따라 성능이 크게 차이가 나게 된다. 배터리는 통상적으로 상온에서 작동해야 최대의 효율을 가질 수 있으나, 그 밖의 온도, 특히 고온에서는 전해질 분해가 일어나게 되어 배터리의 수명이 현저히 떨어지는 문제점이 있다.Recently, the automobile industry is concentrating on the development and manufacture of electric vehicles that do not use petroleum energy, or hybrid vehicles that use electric energy and energy as appropriate. Here, a large-capacity battery is mounted in an electric vehicle, and performance of the battery varies greatly depending on the temperature. The battery typically has to operate at room temperature to have the maximum efficiency, but electrolyte decomposition occurs at other temperatures, especially at high temperatures, resulting in a problem that the life of the battery is significantly reduced.
이러한 문제점을 해결하기 위해서 종래에는 송풍 팬을 통해 차량 외부의 공기를 끌어들여 배터리를 냉각시키거나, 차량 실내공기를 전동팬을 이용하여 배터리팩으로 유입시켜 배터리의 온도를 하강시키는 구성을 가지고 있다. 이는 차량의 실외공기 또는 차량의 실내공기 둘 중의 하나만을 이용하기 때문에 실내외공기의 상태에 따라 배터리 냉각 효율의 편차가 크게 늘어날 수 있다는 문제점이 있다.In order to solve such a problem, conventionally, air is drawn from outside of the vehicle through a blowing fan to cool the battery, or the indoor air of the vehicle is introduced into the battery pack using the electric fan to lower the temperature of the battery. Since the outdoor air of the vehicle or the indoor air of the vehicle is used, there is a problem that the variation of the cooling efficiency of the battery greatly increases depending on the state of the indoor / outdoor air.
게다가, 특히 여름에는 외부로부터 유입되는 공기에 다량의 습기가 포함되어 있는데, 습도가 높으면 비열 또한 높아져서 같은 온도의 건조한 공기에 비하여 냉각효과가 떨어지는 단점이 있어 효율적으로 배터리를 냉각시키는 것에 한계가 있다.In addition, especially in summer, a large amount of moisture is contained in the air introduced from the outside. However, when the humidity is high, the specific heat also increases, and the cooling effect is lower than that of the dry air at the same temperature.
또한, 송풍 팬 또는 전동팬을 구동함으로써 발생하는 에너지 소모가 추가로 발생된다는 점에서 연비효율을 최우선으로 하는 전기자동차 또는 하이브리드 자동차에 적합하지 않다는 문제점이 있다.Further, there is a problem that energy consumption generated by driving the blowing fan or the electric fan is additionally generated, which is not suitable for an electric vehicle or a hybrid vehicle whose fuel efficiency is the top priority.

본 발명은 이와 같은 한계를 극복하기 위해 안출된 것으로, 본 발명의 목적은 송풍 팬과 같은 동력을 사용하지 않아 추가적인 에너지 소모 없이 자동차 외부 또는 내부의 공기를 배터리팩 룸으로 유입시키되, 유입되는 공기에 대해 유동가이드 역할을 하여 유입되는 공기가 접촉된채 흐르게 되는 냉각핀을 설치하여 유입되는 공기의 온도를 더 낮추고, 이러한 공기를 배터리팩 룸 내부로 공급하여 배터리의 온도를 하강시키고,SUMMARY OF THE INVENTION The present invention has been made to overcome the above problems, and it is an object of the present invention to provide an air conditioner which does not use a power such as a blower fan to introduce air outside or inside a vehicle into a battery pack room without additional energy consumption, A cooling pin is provided to allow the air to flow in contact with the flow guide to further lower the temperature of the introduced air and supply the air to the inside of the battery pack room to lower the temperature of the battery,

도 1 내지 도 4에 도시된 바와 같이, 본 발명은 자동차 실외공기와 자동차 실내공기의 냉각된 공기를 이용하여 자동차 배터리팩을 냉각시키고, 자동차 배터리 룸 내부의 열을 배출하는 배터리공조장치에 관한 것으로, 자동차 내부로 유입되는 실외공기(31) 및 자동차 내부의 실내공기(32)의 유동을 제어하고 냉각시켜 자동차에 구비된 배터리팩(50)의 내부는 직접냉각시키고 배터리팩(50)의 외부는 간접냉각시키는 배터리 냉각수단을 포함하여 구성될 수 있다. 공기(30)는 실외공기(31)와 실내공기(32)로 구부하였다.As shown in FIGS. 1 to 4, the present invention relates to a battery air conditioner for cooling an automobile battery pack using the outdoor air of the vehicle and the cooled air of the indoor air, and discharging heat inside the automobile battery room The outside air 31 flowing into the inside of the automobile and the room air 32 inside the automobile are controlled and cooled so that the inside of the battery pack 50 provided in the automobile is directly cooled and the outside of the battery pack 50 is cooled And battery cooling means for indirect cooling the battery. The air 30 is bent into the outdoor air 31 and the indoor air 32.
배터리 냉각수단은, 주 냉각핀(10); 주 냉각핀(10)에 구비되어 실외공기(31)의 흐름을 가이드하는 유동가이드(15); 및 실내공기(32)의 흐름 통로에 구비되어 실내공기의 유동을 제어하는 가변플랩(20);를 포함하여 구성된다.The battery cooling means includes a main cooling fin (10); A flow guide (15) provided in the main cooling fin (10) and guiding the flow of the outdoor air (31); And a variable flap (20) provided in a flow passage of the indoor air (32) to control the flow of indoor air.
여기서, 주 냉각핀(10)은 다수개의 핀이 수직한 방향으로 소정의 이격거리를 가지고 병렬 배치되어 있으며, 다수개의 핀 사이 및 양측 최외각 핀 외측면에는 유동가이드(15)가 결합되어 있다. 또한, 주 냉각핀(10)은 유동가이드(15)를 기준으로 상부 냉각핀(12)과 하부 냉각핀(14)으로 구분되도록 구성된다.Here, the main cooling fin 10 has a plurality of pins arranged in parallel with a predetermined distance in the vertical direction, and a flow guide 15 is coupled between the plurality of pins and the outer surfaces of the outermost pins on both sides. The main cooling fin 10 is configured to be divided into an upper cooling fin 12 and a lower cooling fin 14 based on the flow guide 15.
유입구를 통해 자동차 내부로 유입되는 실외공기(31)는 주 냉각핀(10)의 상부 냉각핀(12)을 거쳐 유동하면서 냉각핀과 접촉과정에서 내포된 열을 빼앗기고 냉각되게 되며 냉각된 실외공기(31c)는 이동하면서 배터리팩(50)의 외부를 간접적으로 냉각시키게 된다. 이때, 주 냉각핀(10)에 일체로 형성되거나 또는 별개로 구비되어 결합된 유동가이드(15)에 의해, 유입된 실외공기(31)는 유동가이드를 따라 상방향으로 이동된 후 실내를 유동하면서 배출구쪽을 향해 이동하게 된다.The outdoor air 31 flowing into the interior of the automobile through the inlet flows through the upper cooling fin 12 of the main cooling fin 10 while the heat contained in the process of contact with the cooling fin is lost and cooled, 31c will indirectly cool the outside of the battery pack 50 while moving. At this time, the outdoor air (31) introduced into the main cooling fin (10) is moved upwards along the flow guide by the flow guide (15) formed integrally with or separately from the main cooling fin And is moved toward the discharge port side.
또한, 본 발명의 일 실시예에 따른 유동가이드(15)는 오목하게 만곡되어진 소정폭을 가진 장방형 띠의 곡면 형태로서, 주 냉각핀(10)을 구성하는 수직한 방향으로 이격 병렬 배치되어 있는 다수개의 핀 사이 및 양측 최외각 핀 외측면에 구비된다. 유동가이드가 공기를 받는 방향으로 오목하게 만곡되어진 장방형 띠의 곡면 형태를 지니고 있어서 실외공기(31)가 상부 냉각핀(12)에 접촉하면서 유동가이드를 따라 자연스럽게 상방향으로 유동하게 되고 이때 상승하는 공기는 냉각 및 제습되는 효과를 갖게 된다.In addition, the flow guide 15 according to the embodiment of the present invention is a curved surface shape of a rectangular band having a predetermined width that is concavely curved, and has a plurality of Between the two pins and on the outer surface of the outermost pin on both sides. The flow guide has a curved shape of a rectangular band curved concavely in the direction of receiving air so that the outdoor air 31 flows naturally upward along the flow guide while contacting the upper cooling fin 12, The cooling and dehumidifying effects are obtained.
또한, 도 4에 도시된 바와 같이, 유동가이드(15)는 소정치수를 가진 다수개의 경사면이 상하 이격배열 및 전후 이격배열되어 형성된 보조 냉각핀(16)으로 형성되거나, 유동가이드(15)에 별도로 보조 냉각핀(16)을 더 구비할 수 있다. 이때, 보조 냉각핀(16)을 구성하는 다수개의 경사면은 유입된 공기가 상방향으로 흐르도록 경사져 있으며, 공기는 보조 냉각핀을 거쳐 이동하면서 접촉하는 상부 냉각핀 및 보조 냉각핀에 의해 공기 온도가 더욱 하강된 냉각 공기가 된다. 4, the flow guide 15 may be formed of an auxiliary cooling fin 16 formed by arranging a plurality of inclined surfaces having predetermined dimensions in a vertically-spaced arrangement and a front-rear spaced arrangement, And may further include an auxiliary cooling fin 16. At this time, the plurality of inclined surfaces constituting the auxiliary cooling fin 16 are inclined so that the inflow air flows upward, and the air is guided by the upper cooling fin and the auxiliary cooling fin, which contact each other while moving through the auxiliary cooling fin, The cooling air is further lowered.
도 4에는, 보조 냉각핀(16)이 상부 냉각핀에 형성된 것만을 도시하였으나, 이에 국한되는 것은 아니며, 하부 냉각핀에도 형성될 수 있다. 물론, 하부 냉각핀에는 경사면 각도가 없거나 매우 작게 구성할 수도 있다.4, only the auxiliary cooling fin 16 is formed on the upper cooling fin. However, the auxiliary cooling fin 16 may be formed on the lower cooling fin. Of course, the lower cooling fin may be configured to have no slant angle or be very small.
이와 같이 주 냉각핀(10)의 이격되어 구성된 다수개의 핀과 그 사이 사이에 형성된 유동가이드(15), 또는 유동가이드(15)와 보조 냉각핀(16)에 의해, 유입된 실외공기 및 실내공기는 냉각핀 사이사이를 통과하는 것이 용이할 뿐만 아니라, 공기와 냉각핀과의 접촉면적이 넓어지게 되어 공기의 냉각이 훨씬 효율적으로 이루어지게 된다.The flow guide 15 or the flow guide 15 and the auxiliary cooling fin 16 formed between the plurality of pins spaced apart from the main cooling fin 10 as described above are used to supply the outdoor air and the indoor air Not only is it easy to pass between the cooling fins, but also the contact area between the air and the cooling fins is widened, so that the cooling of the air can be performed more efficiently.
또한, 주 냉각핀(10)의 하부 냉각핀(14)은 실내공기 유입로(R)와 가변플랩(20) 사이에 위치되도록 구비되어, 자동차 내부로부터 유입된 실내공기(32)가 하부 냉각핀(14)을 거쳐 이동하면서 냉각된 실내공기(32c)가 되도록 한다.The lower cooling pin 14 of the main cooling fin 10 is disposed to be positioned between the room air inflow path R and the variable flap 20 so that the room air 32 introduced from the inside of the automobile is cooled So that the indoor air 32c is cooled while moving through the indoor space 14.
이때, 냉각된 실내공기(32c)는 일부는 주 냉각핀(10)을 따라 상방향으로 이동하면서 온도가 더 하강하게 되고, 온도가 하강한 실내공기(32c)는 냉각된 실외공기(31c)와 합류하여 이동하게 된다. 또한, 냉각된 실내공기(32c)의 다른 일부는 가변플랩(20)을 거쳐 전진이동하며 배터리팩의 내부를 관통하도록 구성되어, 냉각된 실내공기에 의해 배터리팩의 내부는 직접냉각되게 된다. At this time, a part of the cooled room air 32c moves upward along the main cooling fin 10, and the room air 32c whose temperature has dropped is cooled by the cooled outdoor air 31c They are joined and moved. The other part of the cooled room air 32c moves forward through the variable flap 20 and passes through the inside of the battery pack, so that the inside of the battery pack is directly cooled by the cooled room air.
여기서, 가변플랩(20)은 실내공기(32)가 유입되는 실내공기 유입로(R)와 배터리팩(50)을 연결하는 통로에 설치되어, 주 냉각핀(10)의 하부 냉각핀(14)을 거치면서 냉각된 실내공기(32c)가 배터리팩(50) 방향으로 전진이동은 가능하되 후진이동은 방지하도록 제어한다. 또한, 가변플랩은, 실내공기의 유입량을 증가시키면 유동제어 가변플랩이 빠르게 회전하고, 실내공기의 유입량을 감소시키면 유동제어 가변플랩이 느리게 회전함으로써, 배터리팩으로의 실내공기 유입량을 제어하는 역할을 수행한다.The variable flap 20 is installed in a passage connecting the indoor air inflow path R into which the indoor air 32 flows and the battery pack 50 so that the lower flap 14 of the main cooling pin 10 So that the cooled indoor air 32c can be moved forward in the direction of the battery pack 50 but is prevented from moving backward. In addition, in the variable flap, when the inflow amount of the room air is increased, the variable control flap rotates rapidly, and when the inflow amount of the room air is decreased, the variable control flap rotates slowly to control the inflow amount of the room air into the battery pack .
이와 같이, 자동차 내부로 유입되는 실외공기(31)는 배터리 냉각수단의 주 냉각핀(10)의 상부 냉각핀(12)을 거치면서 냉각되고, 냉각된 실외공기(31c)는 이동하면서 배터리팩의 외부를 간접냉각시킨 후 데워진 실외공기(31w)는 배출구쪽으로 이동하여 배출된다. 또한, 자동차 내부의 실내공기(32)는 배터리 냉각수단의 주 냉각핀(10)의 하부 냉각핀(14)을 거치면서 냉각되고, 냉각된 실내공기(32c)의 일부는 냉각핀을 따라 상방향으로 이동하면서 온도가 더 하강하고 온도가 하강한 실내공기(32c)는 냉각된 실외공기(31c)와 합류하여 이동한다. 또한, 냉각된 실내공기(32c)의 다른 일부는 가변플랩(20)을 거쳐 전진이동하며 배터리팩의 내부를 관통하면서 배터리팩의 내부를 직접냉각시킨 후 데워진 실내공기(32w)는 배출구쪽으로 이동하여 배출되는 것이다.As described above, the outdoor air 31 flowing into the automobile is cooled while passing through the upper cooling fin 12 of the main cooling fin 10 of the battery cooling means, and the cooled outdoor air 31c is moved After indirectly cooling the outside, the heated outdoor air (31w) is exhausted toward the exhaust port. The indoor air 32 in the automobile is cooled while passing through the lower cooling fin 14 of the main cooling fin 10 of the battery cooling means and a part of the cooled room air 32c is directed upward The indoor air 32c whose temperature is further lowered and the temperature is lowered moves together with the cooled outdoor air 31c. The other part of the cooled room air 32c moves forward through the variable flap 20 and directly passes through the inside of the battery pack to cool the inside of the battery pack, and the heated room air 32w moves toward the discharge port Is discharged.
본 발명의 실시예에서, 상부 냉각핀(12)을 직각삼각형 형태로 구성하여, 공기가 받는 저항을 최소화하면서 실외공기가 상부 냉각핀의 상단으로 자연스럽게 상승할 수 있도록 하고, 또한 공기가 이동하면서 냉각핀과의 열교환이 활발하도록 접촉면적을 높여 충분히 냉각 및 제습이 될 수 있도록 하였으나, 이와 같은 형태에 국한되는 것은 아니며 여타 주변 부품의 형태에 따라서 또는 효율을 극대화할 수 있는 형태로 다양하게 변형될 수 있음은 물론이다.In the embodiment of the present invention, the upper cooling fin 12 is formed in the shape of a right-angled triangle so that the outdoor air can naturally rise to the upper end of the upper cooling fin while minimizing the resistance received by the air, It is possible to sufficiently cool and dehumidify by increasing the contact area so that the heat exchange with the fin is active. However, the present invention is not limited to this type, and it can be variously modified according to the shape of other peripheral parts or in a form of maximizing efficiency Of course it is.
하부 냉각핀(14) 또한 공기흐름에 방해가 되지 않고, 충분히 냉각 및 제습을 할 수 있는 형태로써 도시된 형태에 국한되지 않고 다양하게 변형될 수 있음은 물론이다.The lower cooling pin 14 is not limited to the shape shown in the figure but can be sufficiently cooled and dehumidified without interfering with the air flow.
또한, 본 발명의 보조 냉각핀(16)의 다수개의 경사면은, 자연스러운 공기흐름을 위해 그 각도가 10~70°가 바람직하나 이에 한정되는 것이 아님은 물론이며, 경사면의 각도를 열마다 다양하게 변화시키거나 변형배치하여 공기가 자연스럽게 흐르면서도 냉각핀과의 접촉면적이 크고 접촉시간이 길도록 구성배치할 수 있다.In addition, the angle of the plurality of slopes of the auxiliary cooling fin 16 of the present invention is preferably in the range of 10 to 70 degrees for natural air flow. Needless to say, the angle is not limited to this, So that the contact area with the cooling fins is large and the contact time is long.
여기서, 상부, 하부 및 보조 냉각핀은 열전달 효율이 높은 금속재가 바람직하고, 유동가이드는 냉각핀과 같은 열전달 금속재를 사용하거나 또는, 플라스틱과 같은 고분자재료를 사용하여도 무방하다. 물론, 이와 같은 재료에 국한되는 것은 아니며, 열전달 효율이 높은 다양한 재질이 이용될 수 있다.Here, the upper, lower and auxiliary cooling fins are preferably made of a metal material having a high heat transfer efficiency, and the flow guide may be made of a heat transfer metal material such as a cooling fin or a polymer material such as plastic. Of course, the material is not limited to such a material, and various materials having high heat transfer efficiency may be used.
또한, 실내공기 유입로(R)는 하부 냉각핀을 지나 배터리팩까지 연통되도록 구비되어 있으며, 유입로를 통해 실내공기가 유입되어 냉각된 후 냉각된 실내공기가 배터리팩까지 이동하게 된다. In addition, the room air inflow path R is provided so as to communicate with the battery pack through the lower cooling fin, so that the indoor air is introduced through the inflow path, cooled, and then the cooled room air is moved to the battery pack.
또한, 자동차 실외공기의 온도가 충분히 낮아서 배터리팩을 냉각하는 것이 용이하다면, 실외공기를 이용하여 냉각하는 비율을 실내공기를 이용하여 냉각하는 비율에 비하여 상대적으로 크게 하고, 실외공기의 온도가 높거나 또는 비로 인하여 습도가 높다면, 실내공기의 냉각 비율을 증대시켜 운용함으로써, 상황과 환경에 맞게 유기적으로 제어할 수 있다.In addition, if the temperature of the outdoor air of the vehicle is sufficiently low to easily cool the battery pack, the cooling rate using the outdoor air is relatively increased as compared with the cooling rate using the indoor air, Or if the humidity is high, the cooling rate of the room air can be increased and operated so that it can be controlled organically according to the situation and environment.
또한, 실외공기가 고온이거나 우천시에는 자동차 사용자들이 통상적으로 에어컨을 사용하게 되므로, 실내공기의 비중이 커지게 되고, 또한 하부 냉각핀과 상부 냉각핀 간의 열전달로 인하여 실외공기의 제습 및 냉각효과가 증대되는 효과가 있게된다. 이를 통하여 우천시 또는 고온 등의 여러 외기 환경에서도 효율적으로 배터리를 냉각시키는 것이 가능하다.In addition, since the air conditioner is usually used by automobile users when the outdoor air is at a high temperature or in the case of rainy weather, the specific gravity of the indoor air is increased, and the heat transfer between the lower cooling fin and the upper cooling fin increases the dehumidifying and cooling effect of the outdoor air . This makes it possible to efficiently cool the battery even in a rainy or high temperature environment.
또한, 본 발명의 능동형 실내외 냉각공기 복합 유동제어 방식의 배터리공조장치는 도 1에 도시된 바와 같이 자동차 실외공기를 받아들이는 상부 냉각핀 전방에 곤충 및 기타 큰 이물질의 유입을 방지할 수 있는 가림막이 설치될 수 있으며, 이 가림막에 온도 및 습도 등을 측정할 수 있는 센서가 부착될 수 있다. 온도 및 습도 등을 체크할 수 있는 센서는 냉각되기 전의 실외공기를 측정하는 것이므로 가림막에 한정하여 부착되는 것이 아님은 자명하다.In addition, as shown in FIG. 1, the battery air conditioner of the active indoor / outdoor cooling-air hybrid flow control system of the present invention includes a shielding film for preventing insects and other foreign substances from entering the front of the upper cooling fins And a sensor capable of measuring temperature, humidity and the like can be attached to the screen. It is obvious that the sensor capable of checking the temperature and the humidity is not limited to the thin film because it measures outdoor air before it is cooled.
또한, 자동차 실내공기의 온도 및 습도 등을 측정하는 센서는 실내공기 유입로에 부착되는 것이 바람직하나, 이에 한정하지 않고 냉각되기 전의 실내공기의 온도 및 습도 등을 측정할 수 있는 곳에 배치하는 것이 바람직하다.In addition, it is preferable that the sensor for measuring the temperature and the humidity of the indoor air of the vehicle is attached to the indoor air inflow path, but the present invention is not limited thereto and it is preferable to arrange the sensor at a place where the temperature and humidity of the room air before being cooled can be measured Do.
이와 같은 센서들을 통하여 자동차 외부의 실외공기와 실내공기의 유입비율을 결정하고 구동할 수 있는 자동 제어 시스템이 구비되어 있음은 물론이다.It is needless to say that an automatic control system capable of determining and driving the inflow rate of outdoor air and indoor air outside the automobile through the sensors is also provided.
본 발명의 능동형 실내외 냉각공기 복합 유동제어 방식의 배터리공조장치는 실외공기의 원활한 공급 및 공기의 흐름을 위해서 배터리팩의 앞부분, 즉 자동차의 전진방향에 설치되는 것이 바람직하다.It is preferable that the battery air conditioner of the active indoor / outdoor cooling / air combined flow control system of the present invention is installed in the front part of the battery pack, that is, the forward direction of the vehicle, for smooth supply of outdoor air and air flow.
