BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a battery pack heat-conducting device and a heat exchange module for an electric vehicle, and more particularly, to a heat-exchanging module for cooling and heating a battery pack. The present invention relates to a heat-exchanging module and a heat-exchanging module for a battery pack of an electric vehicle which can improve the versatility because the heat-exchanging module can be used either as a conventional water-refrigerant plate heat exchanger or as a heat- .

전기자동차는 자동차의 구동 에너지를 기존의 자동차와 같이 화석 연료의 연소로부터가 아닌 전기에너지로부터 얻는 자동차이다. 전기자동차는 배기가스가 전혀 없으며, 소음이 아주 작은 장점이 있으나, 배터리의 무거운 중량, 충전에 걸리는 시간 등의 문제 때문에 실용화되지 못하다가 최근 공해문제의 심각화, 화석 연료의 고갈 등의 문제가 제기되면서 그 개발이 다시 가속화되고 있다.An electric vehicle is an automobile that derives the drive energy of an automobile from electric energy, not from combustion of fossil fuel like existing automobile. Although electric vehicles have no exhaust gas and have a small noise, they are not practical because of the heavy weight of the battery and the time taken to charge the battery. However, recently, problems such as serious pollution problem and depletion of fossil fuel have been raised The development is accelerating again.

배터리는 다수의 배터리 셀이 집약적으로 설치된 배터리 팩으로 이루어질 수 있다.The battery may be a battery pack in which a plurality of battery cells are intensively installed.

그런데, 배터리 팩은 충전 및 방전이 이루어지면 배터리 셀로부터 열이 발생하고, 발생된 열을 그대로 방치시킬 경우 배터리 셀의 성능이 저하되고 배터리 셀의 수명이 단축될 수 있다. 또한, 배터리 팩은 겨울철과 같은 낮은 온도 하에서는 배터리 소모율이 심하여 짧은 시간에 방전되는 문제점이 있다.However, when the battery pack is charged and discharged, heat is generated from the battery cell, and when the generated heat is left as it is, the performance of the battery cell may be deteriorated and the service life of the battery cell may be shortened. In addition, the battery pack has a problem that the battery is discharged in a short period of time because of a high battery consumption rate at a low temperature such as in winter.

따라서, 전기자동차에는 통상적으로 발열되는 배터리 팩을 냉각시키는 냉각시스템 및 낮은 온도의 배터리 팩을 일정 온도까지 가열시키는 가열시스템이 구비되어 있다.Therefore, electric vehicles generally include a cooling system for cooling a battery pack that generates heat and a heating system for heating a battery pack of a low temperature to a predetermined temperature.

도 1은 종래 기술에 따른 전기자동차의 배터리 팩 열관리 장치의 시스템도이다.1 is a system diagram of a battery pack thermal management apparatus for an electric vehicle according to the prior art.

종래 기술에 따른 전기자동차의 배터리 팩 열관리 장치는, 도 1에 도시된 바와 같이, 압축기(1), 응축기(2), 팽창기(3) 및 증발기(4)를 통하여 냉매가 순환되는 냉매 사이클 회로(5a-5b-5c-5d)와, 순환 펌프(8)에 의하여 배터리 팩(10)을 경유하여 물을 순환시키는 열교환수 순환 회로(12a-12b)를 포함한다.1, a battery pack heat-management apparatus of an electric vehicle according to the related art includes a refrigerant cycle circuit (a refrigerant cycle circuit) in which refrigerant is circulated through a compressor 1, a condenser 2, an inflator 3 and an evaporator 4 5a-5b-5c-5d, and a heat exchange water circulation circuit 12a-12b for circulating water through the battery pack 10 by the circulation pump 8. [

여기서, 배터리 팩을 냉각시키기 위한 냉각시스템으로 기능을 하는 경우에는, 냉매 사이클 회로(5a-5b-5c-5d)에서 분기되어 냉매 공급 배관(6)을 통하여 공급된 냉매와, 열교환수 순환 회로(12a-12b)를 순환하는 물이 칠러형 열교환기(7) 내부로 유입되어 열교환되도록 배치되어, 칠러형 열교환기(7)에서 냉각된 물이 배터리 팩(10)으로 유동되어 배터리 팩(10)을 냉각시킨다.Here, when the cooling system functions as a cooling system for cooling the battery pack, the refrigerant branched from the refrigerant cycle circuits 5a-5b-5c-5d and supplied through the refrigerant supply pipe 6 and the heat- 12a-12b flows into the inside of the chiller-type heat exchanger 7 to be heat-exchanged so that the water cooled in the chiller-type heat exchanger 7 flows into the battery pack 10, .

또한, 배터리 팩을 가열시키기 위한 가열시스템으로 기능을 하는 경우에는, 열교환수 순환 회로(12a)의 일부에 별도로 장착된 히팅부(11)에 의하여 열교환수 순환 회로(12a-12b)를 유동하는 물을 가열한 후 배터리 팩으(8)로 유동시켜 배터리 팩(10)을 가열시킨다.In addition, in the case of functioning as a heating system for heating the battery pack, the water flowing through the heat exchange water circulation circuits (12a-12b) by the heating portion (11) separately mounted in a part of the heat exchange water circulation circuit And then flows to the battery pack 8 to heat the battery pack 10.

그러나, 종래 기술에 따른 전기자동차의 배터리 팩 열관리 장치는, 칠러형 열교환기(7)와 히팅부(11)가 별도의 독립된 공간에 설치되는 바 전체적인 배터리 팩의 사이즈를 증대시킴은 물론 중량이 증가하는 문제점을 안고 있다.
However, according to the related art battery pack heat management apparatus of the electric vehicle, since the chiller type heat exchanger 7 and the heating unit 11 are installed in independent spaces, the size of the battery pack as a whole is increased, .

본 발명은 상기한 기술적 과제를 해결하기 위하여 안출된 것으로서, 배터리 팩을 냉각시키거나 가열시키기 위한 냉각수를 냉각 또는 가열시키는 일체형 열교환 모듈을 구비함으로써 전체적인 비용 및 중량을 저감하는 것은 물론 사용례에 따라서 히팅 기능이 삭제된 기존 물-냉매 판형 열교환기 및 히팅 기능을 추가한 열교환 모듈로 이용할 수 있으므로 범용성을 향상시킬 수 있는 전기자동차의 배터리 팩 열관리 장치 및 열교환 모듈을 제공하는 것을 그 목적으로 한다.

한편, 워터재킷(120)은, 사용자의 선택 또는 적용되는 차종에 따라 필요 시 냉매 수용 본체(110)의 상부로부터 탈거될 수 있도록 구비되고, 이를 위해, 워터재킷(120)에는, 상술한 바와 같이 냉매 수용 본체(110)의 상부로 돌출 형성된 냉매 유입 포트(112), 냉매 토출 포트(113) 및 물 토출 포트(111)가 관통되는 복수개의 관통홀(123a 내지 123c)이 각각 대응되는 위치에 형성될 수 있다.On the other hand, the water jacket 120 is provided to be detachable from the upper portion of the refrigerant receiving main body 110, if necessary, according to the user's choice or type of vehicle to be applied. For this purpose, A plurality of through holes 123a to 123c through which the coolant inflow port 112, the coolant discharge port 113 and the water discharge port 111 protruding from the upper portion of the refrigerant receiving main body 110 are passed are formed at corresponding positions .

특히, 워터재킷(120)이 탈거되어 히팅부가 열교환 모듈(100)로부터 분리되어 장착되고, 개별로 작동되도록 설계된 차종에 적용될 경우에는, 워터재킷(120)의 탈거로 물 유입 포트(126)가 제거되는 것인 바, 이 때에는 기존의 본체 유입구(114)에 물 유입 포트(126)와 같은 착탈형 추가 구성이 결합되도록 구비될 수 있음은 물론이다.Particularly, when the water jacket 120 is removed and the heating part is detached from the heat exchange module 100 to be mounted and designed to be operated individually, the water jacket 120 can be removed to remove the water inlet port 126 In this case, it is needless to say that it is possible to provide a detachable additional configuration such as the water inlet port 126 to the conventional body inlet 114.

한편, 가열 히터 패널(125)은, 박막형 히터(130)로부터 발생된 열이 워터재킷(120)의 가열 공간(121) 내측으로 유동되는 물과 직접 접촉되어 물을 가열시키기에 충분하도록 열전도율이 높은 재질로 이루어짐이 바람직하다. 특히, 가열 히터 패널(125)은 적어도 워터재킷(120)의 열전도율보다 높은 재질로 이루어짐으로써 가열 성능을 향상시킬 수 있다.On the other hand, the heated heater panel 125 is formed so that the heat generated from the thin film heater 130 comes into direct contact with the water flowing into the heating space 121 of the water jacket 120, It is preferable that it is made of a material. In particular, the heating heater panel 125 is made of a material at least higher than the thermal conductivity of the water jacket 120, so that the heating performance can be improved.

다만, 가열 히터 패널(125)의 상부면에 구비된 박막형 히터(130)의 경우 양면에서 열을 발생시키는 바 가열 히터 패널(125)의 상부측으로 열손실이 발생될 우려가 있으므로, 도 2에 참조된 바와 같이, 박막형 히터(130)의 상부면을 차폐하여 열손실을 차단하는 단열 패널(140)이 더 구비될 수 있다.However, in the case of the thin film heater 130 provided on the upper surface of the heated heater panel 125, there is a possibility that heat loss occurs to the upper side of the bar heater panel 125 which generates heat on both sides. The heat insulating panel 140 may be further provided to shield the upper surface of the thin film heater 130 to block heat loss.

단열 패널(140)은, 박막형 히터(130)의 열에 의하여 열 변형이 발생되지 않는 정도의 내열성을 가진 재질로 형성되는 것이 바람직하고, 보다 바람직하게는, 열전도율이 낮은 재질로 이루어져 가열 히터 패널(125)의 상측에 구비된 주변 구성의 열 변형을 방지할 수 있어야 한다.The heat insulating panel 140 is preferably made of a material having a heat resistance enough not to be thermally deformed by the heat of the thin film heater 130 and more preferably made of a material having a low thermal conductivity, It is necessary to prevent the thermal deformation of the peripheral structure provided on the upper side.

The heating heater panel 125 constituting the heating portion is detachably installed at any one of a plurality of cooling-type plate heat exchangers 150 arranged continuously in the horizontal direction in the internal space 115 of the refrigerant receiving main body 110 . The piping structure for supplying the water flowing into the heating heater panel 125 may be variously designed, but the detailed description of the connection relationship in the refrigerant receiving main body 110 will be omitted in the present embodiment.

한편, 본 발명에 따른 전기자동차의 배터리 팩 열관리 장치 및 열교환 모듈의 다른 실시예는, 도 7의 (b)에 참조된 바와 같이, 복수개의 축냉식 판형열교환기(150)가 냉매 수용 본체(110)의 내부 공간(115)에 수직방향으로 연속 적층 배치되고, 가열 히터 패널(125)이 복수개의 축냉식 판형열교환기(150) 중 어느 하나의 위치에 교체 가능하게 착탈될 수 있다.7 (b), a plurality of cooling-type plate heat exchangers 150 are installed in the refrigerant receiving main body 110, and the plurality of heat- And the heater heater panel 125 may be detachably installed at any one of the plurality of thecooling plate heat exchangers 150.
