Description

자동차의 통합 열관리 시스템{INTEGRATED HEAT MANAGEMENT SYSTEM OF VEHICLE}Integrated heat management system for automobiles {INTEGRATED HEAT MANAGEMENT SYSTEM OF VEHICLE}

본 발명은 자동차의 통합 열관리 시스템에 관한 것으로서, 보다 상세하게는, 열관리 장치들 간의 연계성 및 부품 공용성을 개선함으로써, 각 열관리 장치들의 성능저하 없이 열교환기 및 PTC 히터의 개수를 줄일 수 있고, 이를 통해, 제조원가를 절감함과 동시에 차량의 연비를 개선할 수 있는 자동차의 통합 열관리 시스템에 관한 것이다.The present invention relates to an integrated thermal management system for automobiles. More specifically, by improving the connectivity and component commonality between thermal management devices, the number of heat exchangers and PTC heaters can be reduced without deteriorating the performance of each thermal management device, and through this, , It is about an integrated thermal management system for automobiles that can reduce manufacturing costs and improve vehicle fuel efficiency at the same time.

친환경 차량의 일례로서, 전기자동차, 하이브리드(Hybrid) 자동차, 연료전지 자동차(이하, "자동차"라 통칭함)등이 있다.Examples of eco-friendly vehicles include electric vehicles, hybrid vehicles, and fuel cell vehicles (hereinafter collectively referred to as “vehicles”).

이러한 자동차는, 다양한 열관리 장치들을 갖추고 있다. 예를 들면, 도 1에 도시된 바와 같이, 차실내 냉,난방을 위한 공조장치(1), 배터리(B)를 냉각시키기 위한 수냉식 배터리 냉각장치(5), 전장부품모듈(C)을 냉각시키기 위한 수냉식 전장부품모듈 냉각장치(7) 등이 있다.These vehicles are equipped with various thermal management devices. For example, as shown in Figure 1, an air conditioning device (1) for cooling and heating the vehicle interior, a water-cooled battery cooling device (5) for cooling the battery (B), and an electric component module (C) for cooling. There is a water-cooled electrical component module cooling device (7) for this purpose.

공조장치(1)는, 히트펌프식(Heat Pump Type)으로서, 냉매의 흐름 방향에 따라 "히트펌프 모드" 또는 "에어컨 모드"로 제어되면서 난방용 또는 냉방용으로 사용한다.The air conditioning device 1 is a heat pump type and is used for heating or cooling while being controlled in “heat pump mode” or “air conditioner mode” depending on the flow direction of the refrigerant.

특히, "히트펌프 모드" 시에는, 압축기(1a)와 고압측 실내열교환기(1b)와 제 1팽창밸브(1c)와 실외열교환기(1d)로 연결되는 "히트펌프 사이클"을 구성하여 냉매를 순환시키고, 이러한 냉매 순환을 통해 고압측 실내열교환기(1b)에 고온의 "열"을 발생시키며, 발생된 "열"을 통해 차실내를 난방한다.In particular, in the "heat pump mode", a "heat pump cycle" connected to the compressor (1a), the high-pressure side indoor heat exchanger (1b), the first expansion valve (1c), and the outdoor heat exchanger (1d) is formed to heat the refrigerant. circulates, and through this refrigerant circulation, high-temperature “heat” is generated in the high-pressure side interior heat exchanger (1b), and the vehicle interior is heated through the generated “heat.”

그리고, "에어컨 모드" 시에는, 압축기(1a)와 고압측 실내열교환기(1b)와 제 2팽창밸브(1e)와 저압측 실내열교환기(1f)로 연결되는 "에어컨 사이클"을 구성하여 냉매를 순환시키고, 이러한 냉매 순환을 통해 저압측 실내열교환기(1f)에 저온의 "냉기"를 발생시키며, 발생된 "냉기"를 통해 차실내를 냉방한다.In addition, in the "air conditioning mode", an "air conditioning cycle" is formed connecting the compressor (1a), the high pressure side indoor heat exchanger (1b), the second expansion valve (1e), and the low pressure side indoor heat exchanger (1f), and the refrigerant circulates, and through this refrigerant circulation, low-temperature “cold air” is generated in the low-pressure side interior heat exchanger (1f), and the vehicle interior is cooled through the generated “cold air.”

배터리 냉각장치(5)는, "냉방모드" 시에는, 공조장치(1)의 냉매를 이용하여 배터리(B)를 냉각시킨다.The battery cooling device 5 cools the battery B using the refrigerant of the air conditioning device 1 in the “cooling mode”.

특히, 바이패스유로(5a)를 통해 공조장치(1)의 냉매를 바이패스하고, 바이패스된 냉매를 팽창밸브(5b)로 팽창,감압시킨 다음, 감압,팽창된 저온의 냉매와 냉각수라인(5c)의 냉각수를 칠러(5d)에서 열교환시켜 냉각수를 냉각시키며, 냉각된 냉각수를 냉각수라인(5c)을 통해 배터리(B)로 순환시킴으로써, 상기 배터리(B)를 냉각시킨다.In particular, the refrigerant of the air conditioning device (1) is bypassed through the bypass passage (5a), the bypassed refrigerant is expanded and decompressed by the expansion valve (5b), and then the decompressed and expanded low-temperature refrigerant and the coolant line ( The coolant in 5c) is cooled by heat exchange in the chiller 5d, and the cooled coolant is circulated to the battery B through the coolant line 5c to cool the battery B.

또한, 차실내의 "난방모드" 시에는, 전장부품모듈 냉각장치(7)의 냉각수를 이용하여 배터리(B)를 냉각시킨다.Additionally, during the “heating mode” inside the vehicle interior, the battery (B) is cooled using the coolant from the electric component module cooling device (7).

특히, 삼방밸브(5e)와 제 1연결라인(5f)을 통해, 전장부품모듈 냉각장치(7)의 냉각수를 도입하고, 도입된 냉각수를 배터리(B)측으로 순환시킨 다음, 순환된 냉각수를 통해 배터리(B)를 냉각시킨다. 이후, 배터리(B)의 냉각을 마친 냉각수를 삼방밸브(5g)와 제 2연결라인(5h)을 통해 전장부품모듈 냉각장치(7)로 리턴시킨다.In particular, the coolant of the electric component module cooling device (7) is introduced through the three-way valve (5e) and the first connection line (5f), the introduced coolant is circulated to the battery (B), and then the coolant is circulated through the circulated coolant. Cool the battery (B). Afterwards, the coolant that has finished cooling the battery (B) is returned to the electric component module cooling device (7) through the three-way valve (5g) and the second connection line (5h).

전장부품모듈 냉각장치(7)는, "냉방모드" 시에는, 삼방밸브(7a)를 제어하여 전장부품모듈(C)측과 라디에이터(7b)측을 연결하고, 이를 통해, 냉각수라인(7c)의 냉각수를 라디에이터(7b)와 전장부품모듈(C) 사이에서 순환시키면서 상기 전장부품모듈(C)을 냉각시킨다.In the “cooling mode,” the electrical component module cooling device (7) controls the three-way valve (7a) to connect the electrical component module (C) side and the radiator (7b) side, and through this, coolant line (7c). The electrical component module (C) is cooled by circulating the coolant between the radiator (7b) and the electrical component module (C).

그리고 차실내의 "난방모드" 시에는, 삼방밸브(7a)를 제어하여 전장부품모듈(C)측과 폐열회수칠러(7d)측을 연결하고, 이를 통해, 냉각수라인(7c)의 냉각수를 폐열회수칠러(7d)와 전장부품모듈(C) 사이에서 순환시키면서 상기 전장부품모듈(C)을 냉각시킨다.And in the "heating mode" inside the vehicle, the three-way valve (7a) is controlled to connect the electrical component module (C) side and the waste heat recovery chiller (7d) side, and through this, the coolant in the coolant line (7c) is used as waste heat. The electrical component module (C) is cooled while circulating between the recovery chiller (7d) and the electrical component module (C).

여기서, 폐열회수칠러(7d)로 도입된 냉각수는, 상기 폐열회수칠러(7d)에서 공조장치(1)의 냉매와 상호 열교환되면서 냉각되는데, 이렇게 냉각된 냉각수는 배터리(B)와 전장부품모듈(C)로 순환되면서 상기 배터리(B)와 전장부품모듈(C)을 냉각시킨다. Here, the coolant introduced into the waste heat recovery chiller (7d) is cooled by mutual heat exchange with the refrigerant of the air conditioning device (1) in the waste heat recovery chiller (7d), and the coolant cooled in this way is used in the battery (B) and the electric component module ( As it circulates through C), it cools the battery (B) and the electric component module (C).

한편, 폐열회수칠러(7d)측에서 열교환된 공조장치(1)의 냉매는, 배터리(B)와 전장부품모듈(C)의 폐열을 흡수하면서 가열되는데, 이렇게 가열된 냉매는 공조장치(1)의 "히트펌프 모드" 효율을 높여 차실내의 난방성능을 개선시킨다.Meanwhile, the refrigerant of the air conditioning device (1) heat-exchanged on the side of the waste heat recovery chiller (7d) is heated while absorbing the waste heat of the battery (B) and the electric component module (C), and the refrigerant heated in this way is heated in the air conditioning device (1). “Heat pump mode” improves heating performance inside the vehicle by increasing efficiency.

다시, 도 1을 참조하면, 자동차의 열관리 장치는, 배터리(B)의 충전 시에, 배터리(B)를 예열하기 위한 배터리 예열장치(8)를 더 구비한다.Referring again to FIG. 1, the thermal management device of the automobile further includes a battery preheating device 8 for preheating the battery B when charging the battery B.

배터리 예열장치(8)는, 배터리 냉각장치(5)의 냉각수라인(5c)상에 설치되는 PTC 히터(8a)를 포함한다.The battery preheating device 8 includes a PTC heater 8a installed on the coolant line 5c of the battery cooling device 5.

PTC 히터(8a)는, 배터리(B)의 충전 시에, 냉각수라인(5c)을 따라 흐르는 냉각수를 가열한다. 따라서 가열된 냉각수가 배터리(B)로 도입되면서 상기 배터리(B)를 예열할 수 있게 한다. 이로써, 배터리(B)의 충전 시에, 충전효율을 높인다.The PTC heater 8a heats the coolant flowing along the coolant line 5c when the battery B is charged. Therefore, the heated coolant is introduced into the battery (B), allowing the battery (B) to be preheated. Accordingly, when charging the battery B, charging efficiency is increased.

그런데, 이러한 종래의 자동차는, 각 열관리 장치들의 부품수가 너무 많다는 단점이 있으며, 이러한 단점 때문에 제조원가가 상승된다는 문제점이 있다.However, these conventional automobiles have the disadvantage that the number of parts for each thermal management device is too large, and this disadvantage causes an increase in manufacturing costs.

특히, 각 열관리 장치들 마다, 열교환기들을 갖추고 있는 데, 예를 들면, 공조장치(1)의 경우, 고압측 실내열교환기(1b)와 저압측 실내열교환기(1f)와 실외열교환기(1d) 등 3개의 열교환기를 갖추고 있다.In particular, each heat management device is equipped with heat exchangers. For example, in the case of the air conditioning device (1), a high-pressure side indoor heat exchanger (1b), a low-pressure side indoor heat exchanger (1f), and an outdoor heat exchanger (1d) ) and is equipped with three heat exchangers.

또한, 배터리 냉각장치(5)의 경우, 칠러(5d), 1개의 열교환기를 갖추고 있으며, 전장부품모듈 냉각장치(7)의 경우, 라디에이터(7b)와 폐열회수칠러(7d) 등 2개의 열교환기를 갖추고 있어, 이러한 총 6개의 열교환기들 때문에 제조원가가 현저하게 상승된다는 문제점이 있다.In addition, the battery cooling device (5) is equipped with a chiller (5d) and one heat exchanger, and the electric component module cooling device (7) is equipped with two heat exchangers, including a radiator (7b) and a waste heat recovery chiller (7d). However, there is a problem that the manufacturing cost increases significantly due to a total of six heat exchangers.

뿐만 아니라, 공조장치(1)의 경우, 난방모드 시에, 부족한 난방성능을 보충하기 위한 별도의 PTC 히터(5i)를 갖춰야 하고, 배터리 예열장치(8)의 경우에도, 배터리(B)의 예열을 위한 별도의 PTC 히터(8a)를 갖춰야 하므로, PTC 히터(5i, 8a)의 개수가 너무 많다는 단점이 있다.In addition, in the case of the air conditioning device (1), in the heating mode, it must be equipped with a separate PTC heater (5i) to supplement the insufficient heating performance, and in the case of the battery preheating device (8), the preheating of the battery (B) is required. Since a separate PTC heater (8a) must be provided for this, there is a disadvantage in that the number of PTC heaters (5i, 8a) is too large.

그리고 이러한 단점 때문에 제조원가가 상승될 뿐만 아니라, 전력소비가 증가되어 차량의 연비에도 많은 지장을 준다는 문제점이 있다.Moreover, due to these shortcomings, not only does the manufacturing cost increase, but there is also a problem in that power consumption increases and the fuel efficiency of the vehicle is greatly affected.

이하, 본 발명에 따른 자동차의 통합 열관리 시스템의 바람직한 실시예를 첨부한 도면에 의거하여 상세히 설명한다.Hereinafter, a preferred embodiment of the integrated thermal management system for an automobile according to the present invention will be described in detail based on the attached drawings.

먼저, 도 2를 참조하면, 본 발명의 통합 열관리 시스템은, 차실내를 냉,난방하는 공조장치(10)를 구비한다.First, referring to FIG. 2, the integrated thermal management system of the present invention includes an air conditioning device 10 that cools and heats the interior of the vehicle.

공조장치(10)는, 히트펌프식으로서, 냉매순환라인(10a)을 구비하며, 상기 냉매순환라인(10a)에는, 압축기(12)와 실외열교환기(13)와 제 1팽창밸브(14)와 실내열교환기(15)가 설치된다.The air conditioning device 10 is a heat pump type and has a refrigerant circulation line 10a, and the refrigerant circulation line 10a includes a compressor 12, an outdoor heat exchanger 13, and a first expansion valve 14. and an indoor heat exchanger (15) are installed.

압축기(12)는, 기화된 냉매를 고온,고압의 가스로 압축한다. The compressor 12 compresses the vaporized refrigerant into a high-temperature, high-pressure gas.

실외열교환기(13)는, 냉방을 위한 "에어컨 모드" 시에는 응축기 역할을 수행하고, 난방을 위한 "히트펌프 모드" 시에는 증발기 역할을 수행한다. 특히, "에어컨 모드" 시에는, 압축기(12)에서 압축된 고온,고압의 냉매를 주변의 공기와 열교환시키고, "히트펌프 모드" 시에는, 칠러(17)(후술함)측에서 배출된 냉매를 주변의 공기와 열교환시킨다.The outdoor heat exchanger 13 functions as a condenser in the “air conditioner mode” for cooling, and as an evaporator in the “heat pump mode” for heating. In particular, in the "air conditioner mode", the high-temperature, high-pressure refrigerant compressed in the compressor 12 exchanges heat with the surrounding air, and in the "heat pump mode", the refrigerant discharged from the chiller 17 (described later) exchanges heat with the surrounding air.

제 1팽창밸브(14)는, 인가되는 전압의 크기에 따라 교축유로(14a)의 개도량이 가변 조절되는 가변식 전자밸브로서, 냉방을 위한 "에어컨 모드" 시에, 실외열교환기(13)에서 배출된 냉매를 저온,저압으로 감압 팽창시킨다.The first expansion valve 14 is a variable solenoid valve in which the opening amount of the throttling passage 14a is variably adjusted according to the magnitude of the applied voltage, and is operated in the outdoor heat exchanger 13 in the “air conditioner mode” for cooling. The discharged refrigerant is reduced and expanded to low temperature and low pressure.

실내열교환기(15)는, 냉방을 위한 "에어컨 모드" 시에 증발기 역할을 수행하는 것으로, 제 1팽창밸브(14)에서 배출된 저온,저압의 냉매를 차실내의 공기와 열교환시켜 냉기를 발생시킨다. 따라서, 차실내를 냉방한다.The indoor heat exchanger (15) performs the role of an evaporator in the “air conditioning mode” for cooling, and generates cold air by exchanging heat with the low-temperature, low-pressure refrigerant discharged from the first expansion valve (14) with the air inside the vehicle. I order it. Therefore, the car interior is cooled.

그리고 공조장치(10)는, 압축기(12)의 출력측(12a)에 설치되는 제 1삼방밸브(16)와, 제 1삼방밸브(16)와 연결되는 칠러(17)와 제 2팽창밸브(18)를 포함한다.And the air conditioning device 10 includes a first three-way valve 16 installed on the output side 12a of the compressor 12, a chiller 17 connected to the first three-way valve 16, and a second expansion valve 18. ) includes.

제 1삼방밸브(16)는, 냉방을 위한 "에어컨 모드" 시에, 압축기(12)로부터 배출되는 고온,고압 냉매의 실외열교환기(13) 도입을 허용하고, 난방을 위한 "히트펌프 모드" 시에, 압축기(12)로부터 배출되는 고온,고압의 냉매를 바이패스한다.The first three-way valve 16 allows the introduction of high-temperature, high-pressure refrigerant discharged from the compressor 12 into the outdoor heat exchanger 13 in the “air conditioner mode” for cooling, and in the “heat pump mode” for heating. At this time, the high temperature and high pressure refrigerant discharged from the compressor 12 is bypassed.

칠러(17)는, 난방을 위한 "히트펌프 모드" 시에, 응축기 역할을 수행하는 것으로, 제 1삼방밸브(16)를 통해 바이패스된 고온,고압의 냉매를 주변의 공기와 열교환시킨다. 특히, 고온,고압의 냉매를 열교환시키는 과정에서 고온의 열을 방출한다.The chiller 17 functions as a condenser in the “heat pump mode” for heating and exchanges heat with the high-temperature, high-pressure refrigerant bypassed through the first three-way valve 16 with the surrounding air. In particular, high-temperature heat is released during heat exchange between high-temperature and high-pressure refrigerants.

제 2팽창밸브(18)는, "히트펌프 모드" 시에, 칠러(17)에서 배출된 냉매를 감압,팽창시키고, 감압,팽창된 저온,저압의 냉매를 실외열교환기(13)에 도입시킨다.In the “heat pump mode,” the second expansion valve (18) depressurizes and expands the refrigerant discharged from the chiller (17), and introduces the depressurized and expanded low-temperature and low-pressure refrigerant into the outdoor heat exchanger (13). .

한편, 실외열교환기(13)는, "히트펌프 모드" 시에, 제 2팽창밸브(18)에서 감압,팽창된 냉매를 주변의 공기와 열교환시키고, 열교환된 냉매를 압축기(12)의 입력측(12b)으로 리턴시킨다.Meanwhile, in the "heat pump mode", the outdoor heat exchanger 13 exchanges heat with the refrigerant decompressed and expanded in the second expansion valve 18 with the surrounding air, and transfers the heat-exchanged refrigerant to the input side of the compressor 12 ( Return to 12b).

여기서, 난방을 위한 "히트펌프 모드" 시에, 실내열교환기(15)측의 제 1팽창밸브(14)는 교축유로(14a)가 완전히 차단되도록 제어된다. 따라서, "히트펌프 모드" 시에는, 실내열교환기(15)로의 냉매 유입을 차단한다. 이로써, 실내열교환기(15)는, 냉방을 위한 "에어컨 모드"일 시에만 작동하도록 구성된다.Here, in the “heat pump mode” for heating, the first expansion valve 14 on the indoor heat exchanger 15 side is controlled so that the throttling passage 14a is completely blocked. Therefore, in “heat pump mode”, the inflow of refrigerant into the indoor heat exchanger (15) is blocked. Accordingly, the indoor heat exchanger 15 is configured to operate only in the “air conditioner mode” for cooling.

그리고 상기 공조장치(10)는, 난방을 위한 "히트펌프 모드" 시에, 상기 칠러(17)에서 방출된 열을 차실내로 전달하는 수냉식 열전달부(20)를 구비한다.Additionally, the air conditioning device 10 includes a water-cooled heat transfer unit 20 that transfers heat emitted from the chiller 17 to the interior of the vehicle in a “heat pump mode” for heating.
