차량용 배터리 냉각장치{A BATTERY COOLING DEVICE FOR VEHICLE}Car Battery Cooler {A BATTERY COOLING DEVICE FOR VEHICLE}

본 발명은 차량용 배터리의 냉각장치에 관한 것으로, 배터리의 과열을 방지할 수 있도록 배터리와 적어도 한쪽 면이 접촉하도록 장착 프레임을 설치하고, 이 배터리 장착 프레임과 배터리 사이에 냉매가 흐르는 튜브를 설치함으로서 배터리가 냉각되도록 구성된 차량용 배터리 냉각장치에 관한 것이다.
The present invention relates to a cooling device for a vehicle battery, and to install a mounting frame so that at least one side of the battery in contact with the battery to prevent overheating of the battery, by installing a tube through which the refrigerant flows between the battery mounting frame and the battery It relates to a vehicle battery cooler configured to cool.

일반적으로 내연기관 자동차는 시동을 걸거나 주요 장치에 전원을 공급하기 위해 차량용 배터리가 장착되어 있는데, 이러한 배터리는 여러개의 셀로 이루어진 케이스가 구비되고, 각 셀마다 양극판과 음극판 및 격리판이 설치되며, 이러한 셀 마다 전해액이 저장된 구조로 실시된다.In general, an internal combustion engine vehicle is equipped with a vehicle battery for starting or supplying power to a main device. The battery has a case composed of several cells, each of which has a positive plate, a negative plate, and a separator. Each cell has a structure in which an electrolyte is stored.

이상과 같은 배터리는 각 셀에 저장된 전해액이 심하게 요동되거나 여름철의 경우, 전해액이 온도가 급격히 상승하여 65℃ 이상으로 상승하면, 배터리의 수명이 단축됨은 물론, 폭발할 위험이 있어 안전상의 문제가 있기 때문에 배터리의 온도가 적정 온도를 유지할 수 있도록 관리가 필요하다.Batteries as described above are severely fluctuated in each cell or in the summer, when the electrolyte temperature rises rapidly to 65 ℃ or more, the battery life is shortened, there is a risk of explosion, there is a safety problem Therefore, it is necessary to manage the temperature of the battery to maintain the proper temperature.

이와 같이 내연기관에 설치된 배터리의 온도를 관리하기 위한 선출원된 기술로는 한국공개특허 제1998-092965호(자동차의 배터리 냉각장치)가 개시된 바 있다.As described above, the Korean Patent Application Publication No. 1998-092965 (battery cooling device for automobiles) has been disclosed as a technique for managing the temperature of a battery installed in an internal combustion engine.

상기 문헌의 기술은 도 1에서와 같이 배터리가 위로부터 끼워지고 배터리와 간격을 두고 이격되며, 상단은 배터리와 밀착되고, 상단에 냉각수가 주입되는 주입구가 형성된 케이스(100)와; 상기 케이스의 주입구에 체결된 캡(110)과; 상기 케이스의 외측면에 설치된 다수의 냉각핀(120)을 포함한 것입니다.The technology of the document is as shown in Figure 1, the battery is inserted from above and spaced apart from the battery, the top is in close contact with the battery, the upper end is formed with an inlet for cooling water injection; A cap 110 fastened to the inlet of the case; It includes a plurality of cooling fins (120) installed on the outer side of the case.

또한 케이스(100)의 바닥으로는 배터리가 안착되는 트레이(130)가 더 설치되며, 상기 트레이(130)의 바닥면에는 내외로 연통되는 다수개의 방열공(131)이 더 설치되는 것입니다.In addition, the bottom of the case 100, the tray 130 is a battery is installed is further installed, the bottom surface of the tray 130 is a plurality of heat dissipation holes 131 communicated in and out is further installed.

이러한 구조는 배터리가 케이스(100) 내에 수납 설치되어야 하므로, 배터리의 장, 탈착이 용이하지 못하고, 더욱이 케이스(100)와 냉각핀(120)은 배터리를 감싸는 형태이기 때문에 오히려 배터리의 자연 방열을 저해하게 된다.This structure is because the battery should be installed and stored in the case 100, the mounting and detachment of the battery is not easy, and furthermore, because the case 100 and the cooling fins 120 are wrapped around the battery to prevent the natural heat dissipation of the battery Done.

더욱이 케이스(100)와 배터리 하부의 트레이(130)는 배터리와 밀착 설치되어 열전도를 통해 배터리의 열을 외부로 방출하는 것이나, 케이스(100)와 트레이(130)는 배터리와 조립되기 위한 조립 공차가 있으므로 열전도 효율이 떨어져 실제로 배터리를 냉각하는 효과를 기대하기 어렵다.
Moreover, the case 100 and the tray 130 under the battery are installed in close contact with the battery to emit heat of the battery to the outside through heat conduction, but the case 100 and the tray 130 have an assembly tolerance for assembling with the battery. Therefore, the thermal conduction efficiency is low, it is difficult to expect the effect of actually cooling the battery.

한편, 최근에는 배터리의 전기에너지를 동력원으로 하여 구동되는 모터를 통해 주행하는 전기자동차(하이브리드 자동차)가 개발되고 있는데, 이러한 전기자동차는 차량의 주행을 위해 전기에너지를 사용하므로 보통 26개 이상의 배터리로 구성된 한 개의 배터리팩이 차량 내에 설치된다.On the other hand, electric vehicles (hybrid cars) that are driven through a motor driven by the electric energy of the battery as a power source have recently been developed. Since such electric vehicles use electric energy to drive a vehicle, they usually have 26 or more batteries. One configured battery pack is installed in the vehicle.

전기자동차의 경우 주행 정도에 따라 배터리의 온도가 지속적으로 상승하기 때문에 배터리의 온도를 적정온도로 유지하기 위한 배터리 냉각장치가 필연적으로 설치되어 있다.In the case of electric vehicles, the temperature of the battery continuously increases according to the driving degree, and thus a battery cooling device is inevitably installed to maintain the temperature of the battery at an appropriate temperature.

상기 배터리 냉각장치로는 공랭식과 수냉식 중에서 선택되어 실시되는데, 먼저 공랭식은 냉각팬을 배터리 트레이에 부착하여 공기를 외부에서 흡입하여 배터리 트레이의 입구 쪽부터 냉각시켜 출구 쪽으로 공기를 흘려보내면서 냉각하는 장치이다.The battery cooling apparatus is selected from an air-cooling type and a water-cooling type. First, the air-cooling type attaches a cooling fan to the battery tray, sucks air from the outside, cools it from the inlet side of the battery tray, and cools it by flowing air toward the outlet. to be.

이러한 공랭식 냉각방법은 입구 쪽에서 데워진 공기가 뒤쪽으로 흐르면서 배터리의 위치에 따른 냉각 정도의 차이가 발생하고, 이에 따라 부분적인 온도 차가 생길 수 있어 배터리의 성능이 저하되는 문제가 있다.The air-cooled cooling method causes a difference in the degree of cooling according to the position of the battery as the air warmed from the inlet flows to the rear, and thus may cause a partial temperature difference, thereby degrading the performance of the battery.

따라서 다수개의 배터리를 고르게 냉각하여 성능을 유지할 수 있는 다양한 냉각장치가 개발되고 있다.
Therefore, various cooling apparatuses have been developed to maintain performance by evenly cooling a plurality of batteries.

이와 같은 전기자동차용 배터리 냉각장치의 종래기술로는 한국등록특허 제10-0534730호(전기자동차용 배터리 트레이 냉각장치)가 개시된 바 있다.As a prior art of such an electric vehicle battery cooling apparatus has been disclosed Korean Patent No. 10-0534730 (electric vehicle battery tray cooling apparatus).

상기 문헌의 기술은 자동차 배터리 트레이(200)의 일측에 장착되어 배터리 트레(200)이 내부로 공기를 흡입하도록 하는 냉각팬(210)과; 상기 배터리 트레이(200) 내부의 온도를 측정하도록 장착되는 온도센서와; 상기 배터리 트레이 내부에 설치되는 배터리(220)의 하부에 장착되어 배터리에서 발생하는 열을 흡열하는 흡열부재(230)와; 상기 흡열부재(230)에 일단이 장착되어 열을 전달하는 히트파이프(240)와; 상기 히트파이프(240)의 타단에 장착되는 발열부재(250)와; 상기 발열부재(250)에 장착되며 양단에 직류전류를 인가하면 일단은 발열하며 타단은 흡열하여 온도 제어되도록 발열부재(250)에 장착되는 펠티에소자(260)와; 상기 냉각팬(210)을 작동하여 배터리 트레이(200)로 공기가 흡입되며 펠티에소자(260)의 작동을 제어하여 히트파이프(240)로 전달되는 배터리(220)의 열이 냉각되도록 구성된다.The technique of the document is mounted on one side of the vehicle battery tray 200 and the cooling fan 210 to allow the battery tray 200 to suck air into the interior; A temperature sensor mounted to measure a temperature inside the battery tray 200; A heat absorbing member 230 mounted below the battery 220 installed inside the battery tray to absorb heat generated from the battery; A heat pipe 240 mounted at one end of the heat absorbing member 230 to transfer heat; A heating member 250 mounted at the other end of the heat pipe 240; A Peltier element 260 mounted on the heat generating member 250 and mounted on the heat generating member 250 so that one end of the heat is generated when the DC current is applied to both ends and the other end is endothermic; Air is sucked into the battery tray 200 by operating the cooling fan 210 and controls the operation of the Peltier device 260 to cool the heat of the battery 220 transferred to the heat pipe 240.

이와 같은 종래의 배터리 냉각장치는 다수개 설치되는 배터리를 한번에 냉각시킬 수 있는 장점이 있으나, 각각의 배터리에 흡열부재와 발열부재 및 펠티에 소자와 히트파이프 및 이들을 수납하는 배터리 트레이를 설치해야 하므로 구조가 복잡하고, 더욱이 냉각팬과 펠티에소자에 별도의 전원을 공급해야 하는 문제가 있다.
Such a conventional battery cooling device has the advantage of cooling a plurality of batteries installed at one time, but the heat absorbing member, the heat generating member, and the Peltier element, the heat pipe, and a battery tray for storing them are installed in each battery. In addition, there is a problem in that separate power must be supplied to the cooling fan and the Peltier device.

본 발명은 상기와 같은 종래기술의 문제점을 개선하기 위한 것으로, 본 발명의 목적은 배터리가 과열되지 않도록 냉각하기 위해 설치되는 튜브와 배터리가 밀착 유지되도록 구성된 차량용 배터리 냉각장치를 제공하는 데에 있다.The present invention is to improve the problems of the prior art as described above, an object of the present invention is to provide a battery cooling device for a vehicle configured to keep the battery and the tube is installed in close contact with the battery so as not to overheat.

또한 설치되는 튜브의 유동을 방지하고, 배터리와의 열교환 면적을 넓혀 열교환 효율을 향상시키는 개선된 구조의 장착 프레임을 포함한 차량용 배터리 냉각장치를 제공하는 데에 또 다른 목적이 있다.
Another object of the present invention is to provide a vehicle battery cooling apparatus including a mounting frame having an improved structure which prevents the flow of the tube to be installed and increases the heat exchange area with the battery to improve the heat exchange efficiency.

A seating part 32 protruding between the tube installation part 31 and contacting one surface of the battery pack 10; A carbon finger part A is formed in the tube installation part 31; The finger portion A is implemented by partially cutting the bottom surface of the tube mounting portion 31 and bending the free end thereof upward.

이와 같은 장착 프레임(30)은 요홈과 요부가 번갈아 형성되어 요홈부에 대응하여 튜브설치부(31)가 형성되고, 요부에 대응하여 안착부(32)가 형성된 것으로, 이러한 튜브설치부(31)에 설치되는 튜브(20)는 양측으로 안착부(32)가 돌출되어 있어 튜브(20)를 고정하게 되고, 이에 의해 튜브(20)가 차량의 진동에 의해 유동되어도 장착 프레임(30)을 이탈하지 않고 고정유지된다.The mounting frame 30 is formed in the groove and the recess alternately formed tube mounting portion 31 corresponding to the recess, and the seating portion 32 is formed corresponding to the recess, such a tube mounting portion 31 The tube 20 to be installed in the mounting portion 32 protrudes to both sides to fix the tube 20, thereby leaving the mounting frame 30 even if the tube 20 flows due to the vibration of the vehicle. It is kept fixed.

장착 프레임(30)에 설치되는 튜브(20)는 그 상부면에 안착되는 배터리팩(10)과 항상 밀착 유지될 수 있도록 탄지부(A)를 구비하고 있는데, 이는 도 4(a)에서와 같이 튜브설치부(31)의 바닥면을 부분 절개하여 그 끝단을 상부로 절곡하여 그 끝단이 튜브설치부(31)의 상부로 돌출되도록 구성하고, 이러한 탄지부(A)를 그 길이방향을 따라 교대로 형성한 것으로 실시될 수 있다.The tube 20 installed on the mounting frame 30 is provided with a finger portion A so that it can be kept in close contact with the battery pack 10 seated on its upper surface, as shown in FIG. The bottom surface of the tube mounting portion 31 is partially cut and its ends are bent upwards, and the ends thereof protrude to the upper portion of the tube mounting portion 31, and such a finger portion A is alternated along its longitudinal direction. It can be carried out by forming.

이렇게 탄지부(A)가 형성된 튜브설치부(31)에 도 5(a, b)에서와 같이 튜브(20)를 안착하면 탄지부(A)에 의해 튜브(20)의 상부면이 안착부(32)의 상부면 보다 돌출되고, 이러한 튜브(20)의 상부에 배터리팩(10)을 안착하면 배터리의 무게로 인해 튜브(20)가 탄지되면서 눌려 결과적으로는 도 5(c)에서와 같이 배터리팩(10)이 안착부(32)에 의해 지지되면서 튜브(20)가 탄지된 상태를 유지하게 된다.When the tube 20 is seated on the tube mounting portion 31 having the carbon portion A formed thereon as shown in FIGS. 5A and 5B, the upper surface of the tube 20 is seated by the finger portion A.
