본 발명은 에어 냉온 장치 및 전기자동차용 배터리 온도 조절 시스템에 관한 것으로, 보다 상세하게는 냉각 성능 및 온도 조절 성능이 향상된 에어 냉온 장치 및 에어 냉온 장치를 이용한 전기자동차용 배터리 온도 조절 시스템에 관한 것이다.The present invention relates to an air cooling/heating device and a battery temperature control system for an electric vehicle, and more particularly, to an air cooling/heating device with improved cooling performance and temperature control performance, and a battery temperature control system for an electric vehicle using the air cooling/heating device.

일반적으로 볼텍스 튜브(Vortex Tube)는 산업현장 곳곳의 국부적 냉각문제에 대한 해결책으로 사용되고 있으며, 산업현장에서 사용되는 일반적인 압축공기(컵프레서)를 구동 에너지원으로 사용한다.In general, a vortex tube is used as a solution to the local cooling problem in various industrial sites, and general compressed air (cup presser) used in industrial sites is used as a driving energy source.

볼텍스 튜브는 기계적 구동부가 전혀 없이 차가운 공기와 뜨거운 공기의 흐름을 동시에 만들어 낸다. 그리고 볼텍스 튜브는 비용이 저렴하며 신뢰성이 높고 유지보수의 필요성이 전혀 없는 냉각장치로 고온의 산업 현장에서 이용되고 있다.A vortex tube creates a simultaneous flow of cold and hot air without any mechanical actuators. In addition, the vortex tube is a low-cost, reliable, and maintenance-free cooling device that is used in high-temperature industrial sites.

이러한 볼텍스 튜브는 전자 제어 및 통신장비의 냉방, 기계 가공 공정의 국부적 냉각(절삭유 대체), 고온환경에 설치된 CCTV 카메라의 냉각, 용탕의 응고, 납땜 또는 용접부위의 냉각, 대용량 스위칭 소자의 냉각, 고온 메카니칼 실링 부위의 냉각 및 가혹한 저온환경 조성용 성능시험장비 제작 등에 사용되고 있다.These vortex tubes are used for cooling electronic control and communication equipment, local cooling of machining processes (replacing cutting oil), cooling of CCTV cameras installed in high-temperature environments, solidification of molten metal, cooling of soldering or welding areas, cooling of large-capacity switching elements, high temperature It is used for cooling of mechanical sealing parts and manufacturing performance test equipment for harsh low-temperature environment.

도 1은 종래의 볼텍스 튜브의 구조를 도시한 단면도이다.1 is a cross-sectional view showing the structure of a conventional vortex tube.

도 1에 도시된 바와 같이, 종래의 볼텍스 튜브는 압축공기의 주입을 위한 압축공기 주입부(15)가 형성되는 메인바디(10)와 메인바디(10)에 결합되어 냉기와 열기를 발생시키는 볼텍스 발생기(14) 및 볼텍스 발생기(14)와 결합되는 공기순환튜브(12), 메인바디(10)에 결합되는 커버(13) 및 커버(13)에 결합되는 조절밸브(16)와 캡(17)으로 구성된다.As shown in Figure 1, the conventional vortex tube is coupled to the main body 10 and the main body 10 in which the compressed air injection unit 15 for the compressed air injection is formed to generate cold and hot air. The generator 14 and the air circulation tube 12 coupled to the vortex generator 14, the cover 13 coupled to the main body 10, and the control valve 16 and the cap 17 coupled to the cover 13 is composed of

종래의 볼텍스 튜브는 주입구(15)로부터 공급된 압축공기가 볼텍스발생기(14)와 공기순환튜브(12)를 거치며 냉기와 열기로 분리되어 열기는 공기순환튜브(12)의 일측에 배치된 조절밸브(16)와의 틈새를 통해 외부로 배출되고, 냉기는 전방의 분사구를 통해 분사되는 구조로 열기의 배출이 원활하게 이루어질수록 그 효율이 높아지게 된다.In the conventional vortex tube, compressed air supplied from the inlet 15 passes through the vortex generator 14 and the air circulation tube 12 and is separated into cold and hot air, and the hot air is a control valve disposed on one side of the air circulation tube 12 . (16) is discharged to the outside through the gap, and the cold air is injected through the front injection port, the more smoothly the discharge of the hot air is made, the higher the efficiency.

도 2는 볼텍스 튜브의 내부 유동을 나타낸 도면이다.2 is a view showing the internal flow of the vortex tube.

도 2에 도시된 바와 같이, 압축공기가 볼텍스 튜브로 공급되면 이 공기는 노즐을 통하여 볼텍스 회전실의 안쪽 측면에 접하면서 튜브의 길이방향에 수직으로 분사된다.As shown in FIG. 2 , when compressed air is supplied to the vortex tube, the air is vertically sprayed in the longitudinal direction of the tube while in contact with the inner side of the vortex rotation chamber through the nozzle.

이렇게 분사된 공기는 회오리바람과 같은 와류를 형성하며 튜브의 안쪽 벽면을 타고 돌면서 튜브의 끝쪽으로 이동한다. 이때, 튜브의 끝부분에 달린 밸브를 조금 열면 더워진 공기가 일부 외부로 배출되고 배출되지 않은 나머지 공기는 다시 방향을 바꾸어 튜브의 중심부를 따라 작은 볼텍스를 형성한 체 역류한다. 2차로 형성된 내부의 볼텍스는 열을 잃어버려 냉각된 채 튜브의 반대편 끝으로 배출되는 것이다.The blown air forms a whirlwind-like vortex and moves toward the end of the tube as it spins along the inner wall of the tube. At this time, if the valve attached to the end of the tube is slightly opened, some of the heated air is discharged to the outside, and the remaining air that has not been discharged changes direction again and flows back through the body forming a small vortex along the center of the tube. The secondary formed internal vortex loses heat and is cooled and discharged to the other end of the tube.

한편, 전기자동차에는 동력원으로써 배터리가 설치된다. 이러한 배터리는 온도에 따라 배터리 성능 및 효율에 영향을 받는다. Meanwhile, a battery is installed as a power source in an electric vehicle. These batteries are affected by temperature and battery performance and efficiency.

상기 공기순환튜브에는 상기 온기배출구를 통해 배출되는 온기의 양을 조절하는 조절밸브가 결합된다.A control valve for controlling the amount of heat discharged through the heat outlet is coupled to the air circulation tube.

전기자동차용 배터리 온도 조절 시스템은 전기자동차에 설치되어 차량의 동력원으로 사용되는 배터리와 상기 배터리의 온도를 조절하는 에어 냉온 장치로 이루어지며, 상기 배터리는 배터리셀과 상기 배터리셀을 감싸는 케이스를 포함하고, 상기 에어 냉온 장치는, 압축공기가 유입되는 압축공기 유입구와 냉기가 배출되는 냉기배출구가 형성되는 본체와, 상기 본체로부터 돌출형성되고 상기 압축공기로부터 분리된 온기가 배출되는 온기배출구가 형성되며 상기 압축공기가 이동하면서 상기 온기와 냉기로 분리되는 공기순환튜브와, 상기 본체의 내부에 삽입되고 상기 압축공기를 회전시켜 상기 공기순환튜브로 전달하는 볼텍스 발생부와, 상기 공기순환튜브의 외부를 감싸는 열전달 파이프와, 상기 열전달 파이프 내부에 충전되어 상기 공기순환튜브 내부 공기와 열전달이 이루어지는 열전달유체를 포함하며, 상기 공기순환튜브는 상기 배터리 케이스를 관통하고, 상기 열전달 파이프는 상기 배터리 케이스 내부에 위치하며, 상기 배터리 케이스 내부 온도가 상기 열전달유체의 온도보다 낮으면 상기 열전달유체의 열이 상기 배터리 케이스 내부로 방출되어 상기 배터리 케이스의 내부 온도가 상승한다.A battery temperature control system for an electric vehicle consists of a battery installed in an electric vehicle and used as a vehicle power source and an air cooling/heating device for controlling the temperature of the battery, the battery comprising a battery cell and a case surrounding the battery cell, , The air cooling and heating device includes a main body having a compressed air inlet through which compressed air is introduced and a cold air outlet through which cold air is discharged, and a hot air outlet protruding from the main body and discharging warm air separated from the compressed air. An air circulation tube that is separated into the warm and cold air as the compressed air moves, a vortex generator that is inserted into the body and rotates the compressed air to transfer the compressed air to the air circulation tube, and surrounds the outside of the air circulation tube a heat transfer pipe, and a heat transfer fluid charged in the heat transfer pipe to conduct heat transfer with the air inside the air circulation tube, the air circulation tube passing through the battery case, and the heat transfer pipe being located inside the battery case, , when the internal temperature of the battery case is lower than the temperature of the heat transfer fluid, the heat of the heat transfer fluid is released into the battery case to increase the internal temperature of the battery case.

그리고 상기 배터리 케이스 내부 온도가 상기 열전달유체의 온도보다 높으면 상기 열전달유체가 상기 배터리 케이스 내부의 열을 흡수하여 상기 배터리를 냉각시킨다.And when the internal temperature of the battery case is higher than the temperature of the heat transfer fluid, the heat transfer fluid absorbs heat inside the battery case to cool the battery.

본 발명의 에어 냉온 장치는 압축공기가 온기와 냉기로 분리되어 흐를 때 열전달 파이프 내부에 충전된 열전달 유체가 온기의 열을 흡수함으로써 온기배출구를 통해 배출되는 온기의 온도가 낮아지게 되고, 온기와 분리되는 냉기의 온도가 더욱 낮아지게 되어 냉각 성능 및 효율을 향상시킬 수 있다.In the air cooling/heating device of the present invention, when compressed air flows separately into hot and cold air, the heat transfer fluid filled in the heat transfer pipe absorbs the heat of the warm heat, so that the temperature of the heat discharged through the hot air outlet is lowered, and the temperature is separated from the warm air The temperature of the cold air to be used is further lowered, so that the cooling performance and efficiency can be improved.

또한, 본 발명은 전기자동차용 배터리의 케이스 내부로 공기순환튜브를 감싸는 열전달 파이프가 통과하면서 배터리 케이스 내부에서 효과적으로 열을 발산함으로써 저온의 환경에서 배터리 성능 및 효율이 저하되는 것을 방지할 수 있다.In addition, the present invention can prevent deterioration of battery performance and efficiency in a low-temperature environment by effectively dissipating heat inside the battery case while the heat transfer pipe surrounding the air circulation tube passes into the case of the battery for an electric vehicle.

또한, 전기자동차용 배터리가 과열될 경우에는 케이스 내부를 통과하는 열전달 파이프에 충전되어 있는 열전달 유체가 배터리 케이스 내부의 열을 흡수함으로써 과열된 배터리를 효과적으로 냉각시킬 수 있다.In addition, when the battery for the electric vehicle is overheated, the heat transfer fluid charged in the heat transfer pipe passing through the case absorbs the heat inside the battery case, thereby effectively cooling the overheated battery.

공기순환튜브(200)는 본체(100)로부터 돌출형성된다. 공기순환튜브(200)와 냉기 배출구는 본체(100)에서 서로 반대편 측에 형성된다. 이러한 공기순환튜브(200)에는 온기배출구(210)가 형성된다. 그리고 공기순환튜브(200)에는 온기배출구(210)를 통해 배출되는 온기의 양을 조절하는 조절밸브(220)가 결합된다. 온기배출구(210)에서는 압축공기 유입구(110)를 통해 유입된 압축공기가 이동하면서 냉기와 온기로 분리된다. 냉기와 온기는 상대적인 개념으로, 공기의 절대적 온도와 관계없이 유입된 압축공기로부터 분리되는 공기 중 상대적으로 더 높은 온도의 공기가 온기가 되고 상대적으로 너 낮은 온도의 공기가 냉기가 된다.The air circulation tube 200 is formed to protrude from the body 100 . The air circulation tube 200 and the cold air outlet are formed on opposite sides of the main body 100 . The air circulation tube 200 has a heat outlet 210 is formed. And a control valve 220 for controlling the amount of heat discharged through the heat outlet 210 is coupled to the air circulation tube 200 . In the warm air outlet 210, the compressed air introduced through the compressed air inlet 110 moves and is separated into cold and warm air. Cold and warm are relative concepts, and regardless of the absolute temperature of the air, the air with a relatively higher temperature among the air separated from the compressed air becomes warm and the air with a relatively lower temperature becomes cold.

본 발명의 실시예에서 압축공기를 온기와 냉기로 분리하는 방식은 종래의 볼텍스 튜브의 방식과 동일하다.The method of separating compressed air into warm and cold air in an embodiment of the present invention is the same as that of a conventional vortex tube.

열전달 파이프(400)는 공기순환튜브(200)의 외부를 감싸도록 형성되고, 열전달 파이프(400) 내부에 열전달유체가 충전된다. 열전달유체의 충전 후 열전달 파이프(400)의 내부는 밀폐된다. 열전달 파이프(400) 내부에 충전된 열전달유체는 공기순환튜브(200) 내부 공기와 열전달이 이루어진다.The heat transfer pipe 400 is formed to surround the outside of the air circulation tube 200 , and a heat transfer fluid is filled in the heat transfer pipe 400 . After the heat transfer fluid is filled, the inside of the heat transfer pipe 400 is sealed. The heat transfer fluid filled in the heat transfer pipe 400 performs heat transfer with the air inside the air circulation tube 200 .

이와 같이 압축공기가 온기와 냉기로 분리되어 공기순환튜브(200)를 흐를 때 열전달 파이프(400) 내부에 충전되어 있는 열전달 유체(410)가 온기의 열을 흡수함으로써 온기배출구(210)를 통해 배출되는 온기의 온도가 낮아지게 되고, 온기와 분리되는 냉기의 온도가 더욱 낮아지게 되어 냉각 성능 및 효율을 향상시킬 수 있다.As such, when the compressed air is separated into hot and cold air and flows through the air circulation tube 200, the heat transfer fluid 410 filled in the heat transfer pipe 400 absorbs the heat of the warm air and is discharged through the hot air outlet 210. The temperature of the warm air is lowered, and the temperature of the cold air separated from the warm air is further lowered, thereby improving cooling performance and efficiency.

다음은 전기자동차용 배터리 온도 조절 시스템에 대하여 상세히 설명한다. Next, a battery temperature control system for an electric vehicle will be described in detail.

도 4는 본 발명의 실시예에 따른 전기자동차용 배터리 온도 조절 시스템을 개략적으로 나타낸 도면으로, 배터리(500)는 일반적인 내연기관 자동차가 아닌 전기자동차의 구동을 위한 에너지원으로 사용된다. 도 4에서는 배터리 케이스(510) 내부를 통과하게 됨으로써 외부에서 보이지 않는 열전달 파이프(400) 부분을 점선으로 표시하였다.4 is a diagram schematically showing a battery temperature control system for an electric vehicle according to an embodiment of the present invention. The battery 500 is used as an energy source for driving an electric vehicle, not a general internal combustion engine vehicle. In FIG. 4 , a portion of the heat transfer pipe 400 that is not visible from the outside by passing through the inside of the battery case 510 is indicated by a dotted line.

전기자동차용 배터리 온도 조절 시스템은 전기자동차에 설치되어 차량의 동력원으로 사용되는 배터리(500)와 상기 배터리(500)의 온도를 조절하는 에어 냉온 장치로 이루어지고, 전기자동차에 설치되는 배터리(500)는 배터리셀과 배터리셀을 감싸는 케이스(510)를 포함한다.The battery temperature control system for an electric vehicle consists of a battery 500 installed in an electric vehicle and used as a vehicle power source and an air cooling/heating device for controlling the temperature of the battery 500, and a battery 500 installed in the electric vehicle includes a battery cell and a case 510 surrounding the battery cell.

에어 냉온 장치는 전술한 에어 냉온 장치와 같다. 이때, 공기순환튜브(200)는 배터리 케이스(510)를 관통하고, 열전달 파이프(400)는 배터리 케이스(510) 내부에 위치한다. 이에 따라 배터리 케이스(510) 내부 온도가 열전달유체의 온도보다 낮으면 열전달유체의 열이 배터리 케이스(510) 내부로 방출되어 배터리 케이스(510)의 내부 온도가 상승한다. 반대로 배터리 케이스(510) 내부 온도가 열전달유체의 온도보다 높으면 열전달유체가 배터리 케이스(510) 내부의 열을 흡수하여 배터리(500)를 냉각시킨다.The air cooling/heating device is the same as the above-described air cooling/warming device. At this time, the air circulation tube 200 passes through the battery case 510 , and the heat transfer pipe 400 is located inside the battery case 510 . Accordingly, when the internal temperature of the battery case 510 is lower than the temperature of the heat transfer fluid, the heat of the heat transfer fluid is released into the battery case 510 to increase the internal temperature of the battery case 510 . Conversely, when the internal temperature of the battery case 510 is higher than the temperature of the heat transfer fluid, the heat transfer fluid absorbs heat inside the battery case 510 to cool the battery 500 .

또한, 전기자동차용 배터리(500)가 과열될 경우에는 케이스(510) 내부를 통과하는 열전달 파이프(400)에 충전되어 있는 열전달 유체(410)가 배터리 케이스(510) 내부의 열을 흡수함으로써 과열된 배터리(500)를 효과적으로 냉각시킬 수 있다.In addition, when the battery 500 for an electric vehicle is overheated, the heat transfer fluid 410 charged in the heat transfer pipe 400 passing through the inside of the case 510 absorbs the heat inside the battery case 510 and is overheated. The battery 500 can be effectively cooled.
