전기 자동차용 배터리에서 발생하는 열을 재활용하기 위한 열관리 장치{ HEAT MANAGEMENT APPARATUS FOR RECYCLING HEAT FROM ELECTRIC VEHICLE BATTERY}Heat management device for recycling heat generated from electric vehicle batteries{ HEAT MANAGEMENT APPARATUS FOR RECYCLING HEAT FROM ELECTRIC VEHICLE BATTERY}

본 발명은 전기자동차용 배터리의 열관리 장치에 관한 것으로, 특히 하나의 장치에 의해 배터리 냉각과 차량 실내 난방이 가능한 전기 자동차용 배터리에서 발생하는 열을 재활용하기 위한 열관리 장치에 관한 것이다.The present invention relates to a thermal management device for a battery for an electric vehicle, and more particularly, to a thermal management device for recycling heat generated from a battery for an electric vehicle capable of cooling the battery and heating the vehicle interior by one device.

최근 환경문제와 고유가 등으로 인해 전기차와 같은 환경차량에 대한 관심이 높아지고 있으며, 이같은 환경차량에 있어서 고전압 배터리는 전기차를 구성하는 핵심 부품 중 하나이다.Recently, due to environmental problems and high oil prices, interest in environmental vehicles such as electric vehicles is increasing, and in such environmental vehicles, a high voltage battery is one of the core parts constituting an electric vehicle.

이러한, 고전압 배터리는 충방전시에 고온의 열이 발생되는데, 이는 배터리의 성능 및 효율에 상당한 영향을 미치는 주요 요인으로써 필수적으로 관리할 필요성이 있다.The high-voltage battery generates high-temperature heat during charging and discharging, which is a major factor that significantly affects the performance and efficiency of the battery and needs to be managed.

이런 전기 자동차를 구현함에 있어 핵심기술은 배터리 모듈과 관련한 기술이며, 최근 배터리의 경량, 소형화, 짧은 충전시간 등에 대한 연구가 활발히 이루어 지고 있다. 배터리 모듈은 최적의 온도환경에서 사용하여야 최적의 성능과 긴 수명을 유지할 수 있다. 그러나 구동 중 발생하는 열과 외부의 온도변화에 의해 최적의 온도환경에서 사용하기 어렵다.The core technology in implementing such an electric vehicle is a technology related to a battery module, and recently, studies on light weight, miniaturization, and short charging time of batteries have been actively conducted. Battery modules can maintain optimal performance and long life only when used in an optimal temperature environment. However, it is difficult to use it in an optimal temperature environment due to heat generated during driving and external temperature changes.

배터리 모듈의 최적의 온도환경 유지를 위해 종래에는, 배터리 모듈 온도조절을 위한 냉난방 시스템을 차량 실내 공조를 위한 냉난방 시스템과는 별도로 운용하는 기술을 채택하고 있다. 즉, 독립된 2개의 냉난방 시스템을 구축하여 하나는 실내 냉난방에 사용하고, 다른 하나는 배터리 모듈 온도조절을 위한 용도로 활용하고 있는 것이다.In order to maintain the optimal temperature environment of the battery module, conventionally, a technology for operating a cooling/heating system for controlling the temperature of a battery module separately from a cooling/heating system for air conditioning in a vehicle has been adopted. That is, two independent cooling and heating systems are built, one is used for indoor cooling and heating, and the other is used for battery module temperature control.

즉, 배터리 냉각을 위한 냉각시스템과 차량의 실내 난방용 전기 히터를 별도로 구성하여야 함에 따른 전기 자동차의 연비가 줄어들게 되고 전기 자동차의 부품수 증가와 차량의 냉난방 시스템의 구조가 복잡해지는 문제가 있는 것이다.That is, there is a problem in that the fuel economy of the electric vehicle is reduced due to the need to separately configure the cooling system for battery cooling and the electric heater for indoor heating of the vehicle, the number of parts of the electric vehicle is increased, and the structure of the vehicle cooling and heating system is complicated.

본 발명의 전기 자동차의 배터리 열관리 장치(10)는 일측이 전기 자동차의 배터리(100)와 밀접하게 설치되고 내측에 물이 흐르도록 형성되며 전기 자동차의 배터리(100)에서 발생하는 폐열을 수집하여 내측에 흐르는 물을 1차로 가열시키는 몸체(20)와, 상기 몸체(20) 내측의 물이 누수되지 않도록 하는 상부덮개(30)와, 상기 몸체(20)를 배터리(100)측에 설치하기 위한 하부덮개(40)와, 상기 몸체(20)와 상부덮개(30) 사이에 설치되어 배터리(100)의 폐열에 의해 1차 가열된 온수를 열선(51)에 의해 2차로 가열하는 가열판(50)으로 구성된다.The battery thermal management device 10 of an electric vehicle of the present invention has one side installed closely with the battery 100 of the electric vehicle and formed so that water flows inside, and collects waste heat generated from the battery 100 of the electric vehicle to the inside. A body 20 that primarily heats the water flowing in the body 20, an upper cover 30 that prevents water from leaking inside the body 20, and a lower part for installing the body 20 on the battery 100 side. A heating plate 50 that is installed between the cover 40 and the body 20 and the upper cover 30 to heat the hot water that is first heated by the waste heat of the battery 100 by a heating wire 51. It is composed.

상기 몸체(20)는 전기 자동차의 배터리(100)에 설치되며, 일측은 공간부(21)가 형성되고 타측에는 배터리(100)에서 발생한 열에 의해 물이 1차로 가열되는 가열챔버(23)가 형성된다.The body 20 is installed in the battery 100 of an electric vehicle, a space part 21 is formed on one side, and a heating chamber 23 is formed on the other side in which water is firstly heated by heat generated from the battery 100 do.

본 발명의 실시 예로서 상기 몸체(20)는 열전도가 높은 알루미늄소재를 사용하는 것이 바람직하며, 전기 자동차의 주행중 또는 배터리(100) 충전시에 발생하는 열을 몸체(20)를 통해 전달시켜 배터리(100)의 열을 감소시키면서 전달된 폐열을 이용하여 차량 실내 난방을 위한 온수를 생산하기 위해 사용한다.As an embodiment of the present invention, the body 20 is preferably made of an aluminum material having high heat conduction, and heat generated during driving of an electric vehicle or charging the battery 100 is transferred through the body 20 to transmit the battery ( It is used to produce hot water for heating the vehicle interior by using the transferred waste heat while reducing the heat of 100).

전기 자동차의 배터리(100)에 밀착되어 설치되는 몸체(20)의 일측에는 도 3에서와 같이 열관리 장치(10)의 부품이 설치되는 공간부(21)가 형성되며, 상기 공간부(21)에 하부덮개(40)를 덮어 배터리(100)에 부착하여 몸체(20)가 실제 배터리(100)와 밀착되도록 설치하게 된다.On one side of the body 20 installed in close contact with the battery 100 of the electric vehicle, as shown in FIG. 3, a space part 21 in which a component of the thermal management device 10 is installed is formed, and in the space part 21 The lower cover 40 is covered and attached to the battery 100 so that the body 20 is installed in close contact with the actual battery 100.

이때, 공간부(21)이 일측에는 공간부(21) 내에서 발생한 열에 의한 장치의 고장을 방지하기 위한 환풍통로(22)가 형성될 수 있다.At this time, at one side of the space part 21, a ventilation passage 22 for preventing a failure of the device due to heat generated in the space part 21 may be formed.

몸체(20)에 형성된 공간부(21)의 반대편에는 배터리(100)로부터 전달된 폐열에 의해 1차로 물이 가열되는 가열챔버(23)가 형성된다.A heating chamber 23 in which water is first heated by waste heat transferred from the battery 100 is formed on the opposite side of the space 21 formed in the body 20.

도 4를 참조하여 몸체(20)의 구성을 보면, 내측에는 물이 가열되는 가열챔버(23)가 다수의 공간으로 분리형성되고, 가열챔버(23)의 양측단에는 물이 가열챔버(23)내로 들어오는 유입구(24)와, 가열된 물이 배출되어 차량 난방용으로 사용될 수 있도록 하는 배출구(25)가 형성되며, 가열챔버(23)의 가장자리를 빙둘러서는 가열챔버(23)의 누수방지를 위해 상부에 설치되는 가열판(50)과 밀착되도록 하는 실링부재(27)가 설치된다.Referring to the configuration of the body 20 with reference to FIG. 4, a heating chamber 23 in which water is heated is formed separately into a plurality of spaces, and water is heated in both ends of the heating chamber 23. An inlet 24 entering the interior and an outlet 25 for discharging heated water to be used for vehicle heating are formed, and to prevent leakage of the heating chamber 23 around the edge of the heating chamber 23 A sealing member 27 to be in close contact with the heating plate 50 installed on the upper part is installed.

가열챔버(23) 내의 물이 가열되는 구성을 보면, 우선 배터리(100)에서 발생한 폐열을 몸체(20)를 통해 물리적으로 전달받아 가열챔버(23) 내의 물이 1차로 소정의 온도까지 가열되시키게 되고, 배터리(100)의 폐열에 의해 1차 가열된 물을 몸체(20) 상부에 설치된 가열판(50)의 열선(51)에 의해 2차로 난방을 위한 온도까지 물을 가열하여 배출구(25)를 통해 배출하게 된다.Looking at the configuration in which the water in the heating chamber 23 is heated, first, the waste heat generated from the battery 100 is physically transferred through the body 20 so that the water in the heating chamber 23 is first heated to a predetermined temperature. And, by heating the water firstly heated by the waste heat of the battery 100 to the temperature for heating by the heating wire 51 of the heating plate 50 installed on the upper body 20, the discharge port 25 is opened. It is discharged through.

즉, 배터리(100)의 폐열에 의해 1차로 가열된 물을 가열판(50)의 열선(51)에 의해 2차로 가열함에 따라 가열판(50)에 의한 2차 가열의 열효율을 높일 수 있게 된다.That is, water, which is firstly heated by the waste heat of the battery 100, is secondarily heated by the heating wire 51 of the heating plate 50, so that the thermal efficiency of the secondary heating by the heating plate 50 can be increased.

상기 가열챔버(23) 내에는 다수의 공간으로 분리되어 물이 지그재그로 흘러갈 수 있도록 하며, 유입구(24)를 통해 공급된 물이 가열챔버(23)를 따라 흘러가면서 가열되어 배출구(25)를 통해 난방용 온수로 공급된다.The heating chamber (23) is separated into a plurality of spaces to allow water to flow in a zigzag manner, and the water supplied through the inlet (24) is heated while flowing along the heating chamber (23) to open the outlet (25). It is supplied as hot water for heating.

이때, 가열챔버(23) 내에는 물이 흐르는 유로에 다수의 격벽(26)이 형성되어 가열챔버(23)를 따라 흐르는 물에 열 전달이 잘되게 하여 열효율을 높임과 함께 물이 격벽(26)에 의해 형성된 좁은 유로를 통해 용이하게 흘러갈 수 있도록 한다.At this time, in the heating chamber 23, a plurality of partition walls 26 are formed in a flow path through which water flows to facilitate heat transfer to the water flowing along the heating chamber 23 to increase thermal efficiency and allow water to flow to the partition walls 26. It makes it possible to easily flow through the narrow flow path formed by it.

상기 격벽(26)은 가열챔버(23) 전체에 형성될 수 있으며, 바람직하게는 다수의 공간으로 분리된 가열챔버(23)의 꺾임부분에 형성될 수 있다. 즉, 지그재그로 물이 꺾이는 위치에 격벽(26)에 의해 좁은 유로를 형성하여 유속이 빠르게 함으로써 물이 쉽게 흐를 수 있도록 한다.The partition wall 26 may be formed in the entire heating chamber 23, and preferably may be formed in a bent portion of the heating chamber 23 divided into a plurality of spaces. That is, a narrow flow path is formed by the partition wall 26 at a position where water is bent in a zigzag, so that the flow rate is increased so that water can flow easily.

또한, 격벽(26)은 가열챔버(23) 내에 흐르는 물과 몸체(20)가 닿는 면적을 증가시켜 배터리(100)의 폐열이 보다 많은 면적을 통해 물로 전달되도록 하여 가열효율을 높일 수 있는 것이며, 가열판(50)에 의한 2차 가열시에도 격벽(26)을 따라 흐르는 소량의 물을 가열시킴으로써 빠른시간 내에 물이 가열될 수 있는 것이다.In addition, the partition wall 26 increases the area where the water flowing in the heating chamber 23 and the body 20 contact each other so that the waste heat of the battery 100 is transferred to the water through a larger area, thereby increasing the heating efficiency, Even during the secondary heating by the heating plate 50, the water can be heated in a short time by heating a small amount of water flowing along the partition wall 26.

상술한 본 발명의 설명에서는 구체적인 실시 예에 관해 설명하였으나, 여러가지 변형이 본 발명의 범위에서 벗어나지 않고 실시할 수 있다. 따라서 본 발명의 범위는 설명된 실시 예에 의하여 정할 것이 아니고 특허청구범위 및 그 특허청구범위의 균등한 것에 의해 정해져야 한다.In the above description of the present invention, specific embodiments have been described, but various modifications may be made without departing from the scope of the present invention.
