차량용 배터리 히팅 장치 및 이를 구비한 차량용 공조장치{BATTERY HEATING DEVICE FOR VEHICLE AND AIR CONDITIONER FOR VEHICLE THEREWITH}BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a battery heating device for a vehicle,

본 발명은 차량용 배터리 히팅 장치 및 이를 구비한 차량용 공조장치에 관한 것으로, 보다 상세하게는 차량 내부를 난방하며 배터리를 히팅하는 차량용 배터리 히팅 장치 및 이를 구비한 차량용 공조장치에 관한 것이다.BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a vehicle battery heating device and a vehicle air conditioner having the same, and more particularly, to a battery heating device for a vehicle that heats the interior of the vehicle and heats the battery, and a vehicle air conditioner having the same.

최근 자동차는 연소식 엔진을 사용하는 자동차에서 환경친화적이고, 연비를 고려한 또 다른 형태의 자동차, 즉, 하이브리드 자동차나 전기자동차의 개발이 전 세계적으로 활발히 개발되고 있다.Recently, automobiles are being developed in a global environment where automobiles using combustion engines are environmentally friendly, and another type of automobile considering fuel economy, that is, hybrid automobiles and electric automobiles, is being actively developed.

하이브리드 자동차는 기존의 엔진과 전기에너지로 구동되는 모터를 연계하여 두 가지의 동력원으로 구동되고, 전기자동차는 전기에너지로 구동되는 모터만으로 구동된다. 이러한 하이브리드 자동차와 전기자동차는 배기가스에 의한 환경오염의 저감과 함께 연비향상의 효과로 인하여 미국과 일본을 중심으로 최근 각광을 받고 있는 대안적인 차세대 자동차로 자리매김하고 있다.A hybrid vehicle is driven by two power sources in association with a conventional engine and a motor driven by electric energy, and an electric vehicle is driven by a motor driven by electric energy. These hybrid cars and electric vehicles are becoming an alternative next generation automobile that has recently been spotlighted mainly in the United States and Japan due to the reduction of environmental pollution caused by exhaust gas and the improvement of fuel economy.

이러한 하이브리드 자동차나 전기자동차에는 고용량 배터리가 장착되고, 이러한 배터리는 필요시에는 모터로 전력을 공급하고 차량의 감속, 정지시에는 재생동력원으로부터 생성되는 전기에너지를 충전하는 역할을 하고 있다.Such a hybrid vehicle or an electric vehicle is equipped with a high capacity battery, which supplies electric power to the motor when necessary, and charges the electric energy generated from the regenerative power source when the vehicle decelerates or stops.

이와 같은 고용량 배터리는 온도의 영향을 많이 받는다. 즉, 상기 배터리의 온도가 일정범위 내에서는 높으면 높을수록 충전 및 방전량이 증가하여 배터리의 효율이 높아진다. 반면, 겨울철과 같이 실외 온도가 낮은 경우에는 배터리의 온도가 낮아져 충전 및 방전 효율이 떨어짐은 물론 배터리의 용량과 출력이 감소되며 심할 경우 시동이 곤란하게 되는 문제가 발생할 수 있다.Such a high capacity battery is heavily influenced by temperature. That is, the higher the temperature of the battery is within a certain range, the more the charge and discharge amount increases, thereby increasing the efficiency of the battery. On the other hand, when the outdoor temperature is low as in winter, the temperature of the battery is lowered, resulting in a decrease in the charging and discharging efficiency, a decrease in the capacity and the output of the battery, and a difficulty in starting the battery.

상기한 문제를 해결하기 위해 배터리 히팅장치를 통해 배터리의 온도를 일정온도 이상으로 유지하도록 하고 있다.In order to solve the above problem, the temperature of the battery is maintained at a predetermined temperature or higher through the battery heating device.

도 1은 공개특허 2015-0026176(특허문헌 1)에 개시된 종래의 차량용 배터리 히팅장치이다. 도시된 바와 같이, 종래의 차량용 배터리 히팅장치는. 냉방장치(1)와, 배터리냉각장치(2)와, 배터리 히팅수단(3)을 포함하여 구성된다.FIG. 1 is a conventional vehicle battery heating apparatus disclosed in Japanese Patent Application Laid-Open No. 2015-0026176 (Patent Document 1). As shown, a conventional vehicle battery heating apparatus includes: A cooling device 1, a battery cooling device 2, and a battery heating means 3. [

냉방장치(1)는 차량 실내를 냉방하는 장치로서, 냉매순환라인 상에 설치된 압축기(4), 응축기(5), 팽창수단(6), 증발기(7)로 이루어진다. 배터리 히팅수단(3)은, 압축기(4)와 응축기(5) 사이의 냉매순환라인 상에 병렬로 연결되는 분기냉매라인과 냉각수를 열교환하도록 구성된다.The cooling apparatus 1 is an apparatus for cooling the inside of a vehicle and comprises a compressor 4, a condenser 5, an expansion means 6, and an evaporator 7 provided on a refrigerant circulation line. The battery heating means 3 is configured to heat-exchange the cooling water and the branch refrigerant line connected in parallel on the refrigerant circulation line between the compressor 4 and the condenser 5.

즉, 배터리 히팅수단(3)은 기존 냉방장치(1)의 냉매를 열원으로 하여 배터리냉각장치(2)를 순환하는 냉각수를 히팅하고, 히팅된 냉각수는 냉각수순환라인에 연결된 배터리(8)를 히팅할 수 있다.That is, the battery heating means 3 uses the refrigerant of the conventional cooling apparatus 1 as a heat source to heat the cooling water circulating through the battery cooling apparatus 2, and the heated cooling water is supplied to the battery 8, which is connected to the cooling water circulation line, can do.

종래의 차량용 배터리 히팅장치는 냉방장치의 냉매를 열원으로 하기 때문에 냉방장치를 사용하는 경우에만 작동이 가능하다는 문제가 있었다. 특히, 배터리의 히팅이 필요한 경우는 차량의 냉방을 필요로 하지 않는 겨울철인 경우가 대부분이기 때문에 비효율적이라는 문제점이 있었다.The conventional vehicle battery heating apparatus uses the refrigerant of the air conditioner as a heat source, so that it is possible to operate only when the air conditioner is used. Particularly, in the case where battery heating is required, there is a problem in that it is ineffective because most of the cases are winter, which does not require cooling of the vehicle.

At this time, the cooling water heat exchanger 220 serves as a condenser and the outdoor heat exchanger 130 serves as an evaporator.

냉매는 실외 열교환기(130)를 통과한 후 냉매순환라인(R) 상에 설치된 제 3 밸브(165)에 의해 제 2바이패스라인(R2)을 따라 유동하며 실내 열교환기(130)와 제 1 팽창수단(140)을 바이패스한다. 제 3 밸브(165)는 3웨이 밸브의 형태로 마련되어 실외 열교환기(120)를 통과한 냉매를 냉매순환라인(R) 또는 제 2 바이패스라인(R2)으로 개방할 수 있다.The refrigerant flows through the outdoor heat exchanger 130 and then flows along the second bypass line R2 by the third valve 165 installed on the refrigerant circulation line R and flows through the indoor heat exchanger 130 and the first Bypassing the expansion means (140). The third valve 165 is provided in the form of a three-way valve and can open the refrigerant passing through the outdoor heat exchanger 120 to the refrigerant circulation line R or the second bypass line R2.

이때, 제 1 밸브(115) 및 제 2 밸브(155)는 냉매가 냉매순환라인(R)으로 유동할 수 있도록 냉매유로를 개방한다. 그에 따라, 압축기(110를 통과한 냉매는 냉각수 열교환기(330)로 유동되고, 냉각수 열교환기(220)를 통과한 냉매는 제 2 팽창수단(150)을 통과하도록 유동한다.At this time, the first valve (115) and the second valve (155) open the refrigerant passage so that the refrigerant can flow into the refrigerant circulation line (R). Accordingly, the refrigerant that has passed through the compressor 110 flows into the cooling water heat exchanger 330, and the refrigerant that has passed through the cooling water heat exchanger 220 flows to pass through the second expansion means 150.

또한, 냉각수 펌프(250)에 의해 냉각수순환라인(W)도 작동하여 배터리(210)를 히팅시키며 히터 코어(240)에 의해 차량 내부에 난방열을 공급한다.The cooling water circulating line W also operates by the cooling water pump 250 to heat the battery 210 and supply the heating heat to the inside of the vehicle by the heater core 240.

또한, 차량 전장품(180)을 순환하는 냉각수도 순환하며 칠러(190)에서 전장폐열과 냉매가 열교환된다.Also, the cooling water circulating in the vehicle electrical component 180 is circulated, and the chiller 190 exchanges heat between the waste heat and the refrigerant.

제 1 난방모드를 수행하기 위해 순환되는 냉매의 일부가 제습라인(D)을 따라 이동하도록 제 4 밸브(135)가 설치된다. 제 4 밸브(135)는 1웨이 밸브의 형태로 마련되어, 냉매가 실내 열교환기(130)로 유동하거나 유동하지 못하도록 한다.A fourth valve 135 is installed so that a part of the refrigerant circulated for performing the first heating mode moves along the dehumidifying line D. [ The fourth valve 135 is provided in the form of a one-way valve to prevent the refrigerant from flowing or flowing into the indoor heat exchanger 130.

그에 따라, 실외 열교환기(120)에서 압축기(110)로 유동하는 냉매의 일부가 실내 열교환기(130)로 유동될 수 있다. 이때, 실내 열교환기(130)는 증발기 역할을 하기 때문에 증발기를 통과하며 제습이 이루어진다.Accordingly, a part of the refrigerant flowing from the outdoor heat exchanger 120 to the compressor 110 can flow to the indoor heat exchanger 130. At this time, since the indoor heat exchanger 130 serves as an evaporator, it passes through the evaporator and is dehumidified.
