Description

차량의 열관리 시스템{HEAT MANAGEMENT SYSTEM OF VEHICLE}Heat management system of vehicle {HEAT MANAGEMENT SYSTEM OF VEHICLE}

본 발명은 차량의 열관리 시스템에 관한 것으로서, 보다 상세하게는, 배터리의 예열 구조를 개선함으로써, 배터리가 과도하게 예열되는 것을 방지할 수 있고, 이를 통해, 배터리의 과도한 예열로 인한 배터리의 성능저하와, 손상 및 수명 단축 현상을 방지할 수 있는 차량의 열관리 시스템에 관한 것이다.The present invention relates to a thermal management system of a vehicle, and more particularly, by improving the preheating structure of the battery, it is possible to prevent the battery from being excessively preheated, thereby reducing the performance of the battery due to excessive preheating of the battery and The present invention relates to a thermal management system of a vehicle that can prevent damage, shortening, and lifespan.

하이브리드(Hybrid) 차량, 전기 차량 등은(이하, "차량"이라 통칭함), 전기모터와, 각종 전기장치들과, 고용량 배터리를 갖추고 있다.Hybrid vehicles, electric vehicles, etc. (hereinafter referred to as "vehicles") are equipped with electric motors, various electric devices, and high capacity batteries.

특히, 배터리는 충전식으로서, 차량의 전기모터와 각종 전기장치에 전기를 제공한다. 따라서, 차량의 주행을 가능하게 한다.In particular, the battery is rechargeable and provides electricity to the electric motor and various electric devices of the vehicle. Thus, it is possible to drive the vehicle.

한편, 이러한 배터리는, 온도의 영향을 많이 받는다. 특히, 겨울철과 같이 외기의 온도가 낮을 경우에는, 배터리의 온도가 낮아져 충전 및 방전 효율이 떨어지고, 배터리의 용량과 출력이 감소되어 차량의 주행성능과 주행거리가 현저하게 저하되며, 심할 경우 시동이 곤란한 문제가 발생한다.On the other hand, such a battery is greatly influenced by temperature. In particular, when the temperature of the outside air is low, such as in winter, the temperature of the battery is lowered, thereby reducing the charging and discharging efficiency, and the capacity and output of the battery are reduced, which significantly reduces the running performance and the mileage of the vehicle. Difficult problems arise.

따라서, 배터리의 충전과 방전 효율 저하와, 배터리의 용량과 출력 저하를 방지하기 위해서 배터리의 온도를 일정온도 이상으로 예열하는 것이 중요하며, 이를 위해 차량은, 도 1에 도시된 바와 같이, 배터리 예열장치(10)를 갖추고 있다.Therefore, it is important to preheat the temperature of the battery to a predetermined temperature or more in order to reduce the charging and discharging efficiency of the battery and to lower the capacity and output of the battery. The device 10 is provided.

배터리 예열장치(10)는, 공조장치(20)의 냉매를 이용하는 것으로, 공조장치(20)의 히터코어(22)로 유입되는 히터코어측 냉각수순환라인(30)의 고온 냉각수를 바이패스하는 바이패스밸브(12)와, 바이패스 밸브(12)에서 바이패스된 고온 냉각수를 배터리(40)에 순환시킨 후, 다시 히터코어측 냉각수순환라인(30)으로 리턴시키는 바이패스 라인(14)을 포함한다.The battery preheater 10 uses a refrigerant of the air conditioning apparatus 20 and bypasses the high temperature cooling water of the heater core side cooling water circulation line 30 flowing into the heater core 22 of the air conditioning apparatus 20. The pass valve 12 and the bypass line 14 which circulates the high temperature cooling water bypassed by the bypass valve 12 to the battery 40 and then returns to the heater core side cooling water circulation line 30. do.

이러한 배터리 예열장치(10)는, 공조장치(20)의 히터코어(22)로 유입되는 히터코어측 냉각수순환라인(30)의 고온 냉각수를 바이패스한 다음, 이를 배터리(40)로 순환시킴으로써, 상기 배터리(40)를 예열한다.The battery preheater 10 bypasses the high temperature cooling water of the heater core side coolant circulation line 30 flowing into the heater core 22 of the air conditioning apparatus 20, and then circulates it to the battery 40. The battery 40 is preheated.

따라서, 배터리(40)가 일정온도를 유지할 수 있게 한다. 이로써, 겨울철, 낮은 외기온도에도 불구하고, 배터리의 충전과 방전, 용량과 출력이 일정한 성능을 유지할 수 있게 한다.Thus, the battery 40 can maintain a constant temperature. Thus, in winter, despite the low outside temperature, the battery charge and discharge, capacity and output can maintain a constant performance.

여기서, 공조장치(20)는, 히트펌프식(Heat Pump Type)으로서, 냉매순환라인(24)과 히터코어측 냉각수순환라인(30)을 구비한다.Here, the air conditioner 20 is a heat pump type and includes a refrigerant circulation line 24 and a heater core side cooling water circulation line 30.

특히, 히터코어측 냉각수순환라인(30)은, 냉매순환라인(24)의 냉매 열을 전달받는 수냉식 제 1열교환기(32)와, 인가되는 전기에 의해 냉각수를 가열하는 PTC 히터(34) 및, 제 1열교환기(32)와 PTC 히터(34)와 히터코어(22) 사이에서 냉각수를 순환시키는 워터펌프(36)를 포함한다.In particular, the heater core side coolant circulation line 30 includes a water-cooled first heat exchanger 32 that receives the refrigerant heat of the refrigerant circulation line 24, a PTC heater 34 that heats the coolant by electricity applied thereto, and And a water pump 36 for circulating the coolant between the first heat exchanger 32 and the PTC heater 34 and the heater core 22.

워터펌프(36)는, 냉매순환라인(24)의 냉매 열을 전달받은 제 1열교환기(32)측 냉각수와, PTC 히터(34)에 의해 가열된 냉각수 중, 적어도 어느 하나를 히터코어(22)에 순환시킨다. 따라서, 상기 히터코어(22)가 냉각수 열을 차실내로 방출하면서 차실내를 난방할 수 있게 한다.The water pump 36 supplies at least one of the cooling water heated by the PTC heater 34 to the first heat exchanger 32 side cooling water received with the refrigerant heat of the refrigerant circulation line 24 and the heater core 22. Circulate). Accordingly, the heater core 22 can heat the interior of the vehicle while discharging the coolant heat into the vehicle interior.

그런데, 이러한 종래의 배터리 예열장치(10)는, 히터코어측 냉각수순환라인(30)의 고온 냉각수를 직접 바이패스하여 배터리(40)를 직접 예열하는 구조이므로, 배터리(40)의 예열이 과도할 수 있다는 단점이 있다.However, since the conventional battery preheater 10 directly bypasses the high temperature cooling water of the heater core side cooling water circulation line 30 to directly preheat the battery 40, the preheating of the battery 40 may be excessive. The disadvantage is that it can.

특히, 히터코어측 냉각수순환라인(30)의 냉각수 온도가 높을 경우, 이를 이용한 배터리(40)의 예열이 과도할 수 있는데, 이러한 경우, 배터리(40)가 오히려 과열된다는 단점이 있으며, 이러한 단점 때문에 배터리(40)의 성능이 저하되고, 배터리(40)의 수명이 단축되거나 손상된다는 문제점이 있다.In particular, when the coolant temperature of the heater core side coolant circulation line 30 is high, the preheating of the battery 40 using the same may be excessive. In this case, the battery 40 is rather overheated. The performance of the battery 40 is reduced, there is a problem that the life of the battery 40 is shortened or damaged.

또한, 종래의 배터리 예열장치(10)는, 배터리(40)의 온도를 감안하지 않고, 히터코어측 냉각수순환라인(30)의 고온 냉각수를 무조건 바이패스하여 배터리(40)를 예열하는 구조이므로, 고온의 냉각수를 이용한 배터리(40)의 예열이 과도할 수 있다는 단점이 있다.In addition, the conventional battery preheater 10 is a structure that preheats the battery 40 unconditionally bypasses the high temperature cooling water of the heater core side cooling water circulation line 30 without considering the temperature of the battery 40. There is a disadvantage that the preheating of the battery 40 using the high temperature cooling water may be excessive.

그리고 이러한 단점 때문에 배터리(40)가 오히려 과열되어 배터리(40)의 성능이 저하되고, 수명이 단축되거나 손상된다는 문제점이 있다.And because of this disadvantage, the battery 40 is rather overheated, there is a problem that the performance of the battery 40 is reduced, the life is shortened or damaged.

본 발명은 상기와 같은 종래의 문제점을 해결하기 위해 안출된 것으로서, 그 목적은, 배터리의 예열 구조를 개선함으로써, 배터리가 과도하게 예열되는 것을 방지할 수 있는 차량용 열관리 시스템을 제공하는데 있다.SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned conventional problems, and an object thereof is to provide a thermal management system for a vehicle that can prevent the battery from being overheated by improving the preheating structure of the battery.

It further comprises a battery side cooling water circulation line.

바람직하게는, 상기 배터리측 냉각수순환라인은, 상기 히터코어측 냉각수순환라인의 냉각수 열을 전달받는 제 2열교환기와; 상기 제 2열교환기와 배터리 사이에서 냉각수를 순환시켜, 상기 히터코어측 냉각수순환라인의 냉각수 열을 전달받은 상기 제 2열교환기측 냉각수를 상기 배터리에 도입시키는 워터펌프를 포함하는 것을 특징으로 한다.Preferably, the battery-side cooling water circulation line, the second heat exchanger for receiving the heat of the cooling water of the heater core side cooling water circulation line; And a water pump which circulates the cooling water between the second heat exchanger and the battery and introduces the second heat exchanger side cooling water, which has received the cooling water heat from the heater core side cooling water circulation line, into the battery.

그리고 상기 제어부는, 상기 배터리측 냉각수순환라인의 냉각수 온도가 미리 설정된 기준냉각수온도를 초과할 시에, 상기 배터리측 냉각수순환라인의 워터펌프를 오프(OFF)시키는 것을 특징으로 한다.The controller may turn off the water pump of the battery-side coolant circulation line when the temperature of the coolant in the battery-side coolant circulation line exceeds a preset reference coolant temperature.

그리고 상기 제어부는, 상기 배터리측 냉각수순환라인의 냉각수 온도가 상기 기준냉각수온도 이하로 저하될 시에, 상기 배터리측 냉각수순환라인의 워터펌프를 다시 온(ON)시키는 것을 특징으로 한다.The controller may turn on the water pump of the battery-side coolant circulation line again when the coolant temperature of the battery-side coolant circulation line falls below the reference coolant temperature.

본 발명에 따른 차량의 열관리 시스템에 의하면, 히터코어측 냉각수순환라인의 냉각수 열을, 배터리측 냉각수순환라인의 냉각수로 전달받은 다음, 전달받은 냉각수로 배터리를 예열하는 구조이므로, 히터코어측 냉각수순환라인의 냉각수 열로 배터리를 직접 예열하는 종래 기술과 달리, 배터리를 간접적으로 예열할 수 있는 효과가 있다.According to the thermal management system of the vehicle according to the present invention, since the coolant heat of the heater core side coolant circulation line is transferred to the coolant of the battery side coolant circulation line, and then the preheated battery is transferred to the heater core side coolant circulation.

먼저, 본 발명에 따른 차량 열관리 시스템의 특징부를 살펴보기에 앞서, 도 2를 참조하여 차실내를 냉,난방하기 위한 공조장치(20)에 대해 간략하게 설명한다.First, prior to looking at the features of the vehicle thermal management system according to the present invention, a brief description of the air conditioner 20 for cooling and heating the interior of the vehicle with reference to FIG.

특히, 히터코어측 냉각수순환라인(30)은, 냉매순환라인(24)의 압축기(24a)측에서 발생된 냉매열을 히터코어(22)에 전달하는 것으로, 냉매순환라인(24)의 냉매 열을 전달받는 수냉식 제 1열교환기(32)와, 인가되는 전기에 의해 냉각수를 가열하는 PTC 히터(34) 및, 제 1열교환기(32)와 PTC 히터(34)와 히터코어(22) 사이에서 냉각수를 순환시키는 워터펌프(36)를 포함한다.In particular, the heater core side cooling water circulation line 30 transfers the refrigerant heat generated at the compressor 24a side of the refrigerant circulation line 24 to the heater core 22, and the refrigerant heat of the refrigerant circulation line 24.

이러한 히터코어측 냉각수순환라인(30)은, 냉매순환라인(24)의 압축기(24a)측에서 발생된 냉매열을, 냉각수를 통해 전달받고, 냉매열을 전달받은 고온의 냉각수를 히터코어(22)에 순환시킨다. 따라서, 상기 히터코어(22)가 냉각수 열을 차실내로 방출하여, 차실내를 난방할 수 있게 한다.The heater core side cooling water circulation line 30 receives the refrigerant heat generated at the compressor 24a side of the refrigerant circulation line 24 through the cooling water, and receives the high temperature cooling water that receives the refrigerant heat from the heater core 22. Circulate). Accordingly, the heater core 22 discharges the coolant heat into the vehicle compartment, thereby enabling heating of the vehicle compartment.

다음으로, 본 발명에 따른 차량 열관리 시스템의 특징부를 도 2와 도 3을 참조하여 상세하게 설명한다.Next, features of the vehicle thermal management system according to the present invention will be described in detail with reference to FIGS. 2 and 3.

먼저, 도 2를 참조하면, 본 발명의 열관리 시스템은, 배터리 예열장치(50)를 구비한다.First, referring to FIG. 2, the thermal management system of the present invention includes a battery preheater 50.

배터리 예열장치(50)는, 히터코어측 냉각수순환라인(30)의 냉각수 열을 이용하여 배터리(40)를 예열하는 것으로, 배터리측 냉각수순환라인(52)을 포함한다.The battery preheater 50 preheats the battery 40 by using the coolant heat of the heater core side coolant circulation line 30 and includes a battery side coolant circulation line 52.

배터리측 냉각수순환라인(52)은, 히터코어측 냉각수순환라인(30)의 냉각수 열을 배터리(40)측에 전달하는 것으로, 히터코어측 냉각수순환라인(30)의 냉각수 열을 전달받는 수냉식 제 2열교환기(54)와, 제 2열교환기(54)와 배터리(40) 사이에서 냉각수를 순환시키는 워터펌프(56)를 포함한다.The battery side coolant circulation line 52 transmits the coolant heat of the heater core side coolant circulation line 30 to the battery 40 side, and receives a coolant heat of the heater core side coolant circulation line 30. And a water pump 56 for circulating the coolant between the second heat exchanger 54 and the second heat exchanger 54 and the battery 40.

제 2열교환기(54)는, 히터코어측 냉각수순환라인(30)의 냉각수가 순환되는 제 1냉각수유로(54a)와, 배터리측 냉각수순환라인(52)의 냉각수가 순환되는 제 2냉각수유로(54b)를 갖추고 있다.The second heat exchanger 54 includes a first cooling water channel 54a through which the cooling water of the heater core side cooling water circulation line 30 is circulated, and a second cooling water channel through which the cooling water of the battery side cooling water circulation line 52 is circulated. 54b).

상기 제 1 및 제 2냉각수유로(54a, 54b)는, 서로 대응되게 형성되어 히터코어측 냉각수순환라인(30)의 냉각수와, 배터리측 냉각수순환라인(52)의 냉각수를 상호 열교환시킨다.The first and second cooling water passages 54a and 54b are formed to correspond to each other to heat-exchange the cooling water of the heater core side cooling water circulation line 30 and the cooling water of the battery side cooling water circulation line 52.

특히, 도 3에 도시된 바와 같이, 차실내의 난방모드 시에, 히터코어측 냉각수순환라인(30)의 냉각수와, 배터리측 냉각수순환라인(52)의 냉각수를 상호 열교환시킨다.In particular, as shown in FIG. 3, in the heating mode of the vehicle interior, the cooling water of the heater core side cooling water circulation line 30 and the cooling water of the battery side cooling water circulation line 52 are exchanged with each other.

따라서, 차실내의 난방모드 시에, 히터코어측 냉각수순환라인(30)의 냉각수 열이 배터리측 냉각수순환라인(52)의 냉각수로 전달되고, "열"이 전달된 냉각수가 배터리(40)로 순환되면서 상기 배터리(40)를 예열할 수 있게 한다.Therefore, in the heating mode in the vehicle compartment, the coolant heat of the heater core side coolant circulation line 30 is transferred to the coolant of the battery side coolant circulation line 52, and the coolant to which "heat" is transferred is transferred to the battery 40. The battery 40 can be preheated while being circulated.

또한, 상기 제 1 및 제 2냉각수유로(54a, 54b)는, 도 4에 도시된 바와 같이, 차실내의 제습모드 시에, 히터코어측 냉각수순환라인(30)의 냉각수와, 배터리측 냉각수순환라인(52)의 냉각수를 상호 열교환시킨다.In addition, as shown in FIG. 4, the first and second cooling water flow paths 54a and 54b each include a coolant of the heater core side coolant circulation line 30 and a battery side coolant circulation in the dehumidification mode of the vehicle interior. The cooling water of the line 52 is mutually heat exchanged.

따라서, 차실내의 제습모드 시에, 히터코어측 냉각수순환라인(30)의 냉각수 열이 배터리측 냉각수순환라인(52)의 냉각수로 전달되고, "열"이 전달된 냉각수가 배터리(40)로 순환되면서 상기 배터리(40)를 예열할 수 있게 한다.Therefore, in the dehumidification mode in the cabin, the coolant heat of the heater core side coolant circulation line 30 is transferred to the coolant of the battery side coolant circulation line 52, and the coolant to which "heat" is transferred is transferred to the battery 40. The battery 40 can be preheated while being circulated.

또한, 상기 제 1 및 제 2냉각수유로(54a, 54b)는, 도 5에 도시된 바와 같이, 실외열교환기(24b)의 제상모드 시에, 히터코어측 냉각수순환라인(30)의 냉각수와, 배터리측 냉각수순환라인(52)의 냉각수를 상호 열교환시킨다.In addition, as shown in FIG. 5, the first and second cooling water flow paths 54a and 54b may include cooling water of the heater core side cooling water circulation line 30 in the defrost mode of the outdoor heat exchanger 24b, The cooling water of the battery-side cooling water circulation line 52 is exchanged with each other.

따라서, 실외열교환기(24b)의 제상모드 시에, 히터코어측 냉각수순환라인(30)의 냉각수 열이 배터리측 냉각수순환라인(52)의 냉각수로 전달되고, "열"이 전달된 냉각수가 배터리(40)로 순환되면서 상기 배터리(40)를 예열할 수 있게 한다.Therefore, in the defrost mode of the outdoor heat exchanger 24b, the coolant heat of the heater core side coolant circulation line 30 is transferred to the coolant of the battery side coolant circulation line 52, and the coolant with "heat" is transferred to the battery. Circulating to 40 allows preheating of the battery 40.

이러한 배터리측 냉각수순환라인(52)에 의하면, 히터코어측 냉각수순환라인(30)의 냉각수 열을 전달받아 배터리(40)를 예열하는 구조이므로, 히터코어측 냉각수순환라인(30)의 냉각수 열로 배터리(40)를 직접 예열하는 종래의 구조와 달리, 배터리(40)를 간접적으로 예열할 수 있다.According to the battery-side coolant circulation line 52, since the coolant heat of the heater core-side coolant circulation line 30 is received to preheat the battery 40, the battery is the coolant heat of the heater core-side coolant circulation line 30. Unlike the conventional structure in which 40 is directly preheated, the battery 40 may be indirectly preheated.

따라서, 히터코어측 냉각수순환라인(30)의 고온 냉각수가, 배터리(40)를 직접 예열하는 것에 따른 배터리(40)의 과열 우려를 원천적으로 방지한다. 이로써, 배터리(40)의 과열로 인한 배터리의 성능저하와, 손상 및 수명 단축 현상을 미연에 방지할 수 있게 된다.Therefore, the high temperature cooling water of the heater core side cooling water circulation line 30 prevents the overheating concern of the battery 40 by preheating the battery 40 directly. As a result, performance degradation, damage, and shortening of the battery due to overheating of the battery 40 can be prevented in advance.

여기서, 배터리측 냉각수순환라인(52)은, 배터리(40)의 냉각을 위해 설치된 기존의 배터리 냉각장치(60)용 배터리측 냉각수순환라인(52)을 이용하는 것이 좋다.Here, the battery side coolant circulation line 52 may use the battery side coolant circulation line 52 for the existing battery cooling device 60 installed for cooling the battery 40.

따라서, 별도의 냉각수순환라인을 설치하지 않고서도, 배터리(40)를 예열할 수 있고, 이를 통해, 원가 절감의 효과를 기대할 수 있다.Therefore, the battery 40 can be preheated without installing a separate cooling water circulation line, and thus, a cost reduction effect can be expected.

배터리 냉각장치(60)는, 공조장치(20)의 냉매를 이용하는 것으로, 공조장치(20)의 냉매를 바이패스하는 바이패스유로(62)와, 바이패스유로(62)의 냉매를 팽창,감압시키는 팽창밸브(64)와, 감압,팽창된 냉매를 통해 냉기를 발생시키는 제 3열교환기(66)와, 제 3열교환기(66)에서 발생된 냉기를 상기 배터리(40)측에 전달하는 상기 배터리측 냉각수순환라인(52)을 포함한다.The battery cooling device 60 uses the refrigerant of the air conditioning apparatus 20, and expands and decompresses the bypass passage 62 for bypassing the refrigerant of the air conditioning apparatus 20 and the refrigerant of the bypass passage 62. The third heat exchanger 66 for generating cold air through the expansion valve 64, the decompression, and the expanded refrigerant, and the cold air generated in the third heat exchanger 66 to the battery 40 side. The battery side cooling water circulation line 52 is included.

특히, 제 3열교환기(66)는, 도 6에 도시된 바와 같이, 차실내의 냉방모드 시에, 냉매순환라인(24)의 냉매와 배터리측 냉각수순환라인(52)의 냉각수를 상호 열교환시키는 것으로, 냉매순환라인(24)에서 발생된 냉기를 배터리측 냉각수순환라인(52)의 냉각수에 전달한다.In particular, as shown in FIG. 6, the third heat exchanger 66 exchanges heat between the refrigerant of the refrigerant circulation line 24 and the cooling water of the battery-side cooling water circulation line 52 in the cooling mode of the vehicle interior. In this case, the cool air generated in the refrigerant circulation line 24 is transferred to the cooling water of the battery side cooling water circulation line 52.

따라서, 냉매순환라인(24)의 냉기를 전달받은 배터리측 냉각수순환라인(52)의 냉각수가, 배터리(40)로 순환되면서 상기 배터리(40)의 냉각시킬 수 있게 한다.Therefore, the coolant of the battery-side cooling water circulation line 52 which has received the cool air of the refrigerant circulation line 24 may be cooled in the battery 40 while being circulated to the battery 40.

다시, 도 2를 참조하면, 상기 배터리 예열장치(50)는, 제어부(70)를 더 포함한다.Referring back to FIG. 2, the battery preheater 50 further includes a controller 70.

제어부(70)는, 마이크로 프로세서를 갖추고 있는 것으로, 냉각수온도 감지센서(72) 또는 배터리온도 감지센서(74)로부터 입력된 냉각수 온도 또는 배터리 온도에 따라 히터코어측 냉각수순환라인(30)의 워터펌프(36)와, 배터리측 냉각수순환라인(52)의 워터펌프(56) 중 적어도 어느 하나를 가변제어하도록 구성된다.The control unit 70 is equipped with a microprocessor, and the water pump of the heater core side coolant circulation line 30 according to the coolant temperature or the battery temperature input from the coolant temperature sensor 72 or the battery temperature sensor 74. And at least one of the water pump 56 of the battery-side cooling water circulation line 52.

특히, 냉각수온도 감지센서(72)에서 입력된 배터리측 냉각수순환라인(52)의 냉각수 온도가 미리 설정된 기준냉각수온도를 초과할 시에, 배터리측 냉각수순환라인(52)의 워터펌프(56)를 오프(OFF)시키도록 구성된다.In particular, when the coolant temperature of the battery-side coolant circulation line 52 input from the coolant temperature sensor 72 exceeds the preset reference coolant temperature, the water pump 56 of the battery-side coolant circulation line 52 is turned off. Configured to be OFF.

따라서, 과도한 온도의 냉각수가 배터리(40)에 순환되는 것을 방지한다. 이로써, 과도한 온도의 냉각수로 인한 배터리(40)의 과열을 미연에 방지한다.Thus, excessive temperature cooling water is prevented from circulating in the battery 40. This prevents overheating of the battery 40 due to excessive temperature of the cooling water.

여기서, 제어부(70)는, 냉각수온도 감지센서(72)에서 입력된 배터리측 냉각수순환라인(52)의 냉각수 온도가 기준냉각수온도 이하로 저하될 시에는, 배터리측 냉각수순환라인(52)의 워터펌프(56)를 다시 온(ON)시키도록 구성된다. 따라서, 배터리(40)의 예열이 재개될 수 있도록 구성된다.Here, the control unit 70, when the coolant temperature of the battery-side coolant circulation line 52 input from the coolant temperature sensor 72 is lowered below the reference coolant temperature, the water of the battery-side coolant circulation line 52 The pump 56 is configured to turn on again. Thus, the preheating of the battery 40 can be resumed.

한편, 제어부(70)는, 배터리온도 감지센서(74)에서 입력된 배터리(40)의 온도가 미리 설정된 기준배터리온도를 초과할 시에, 배터리측 냉각수순환라인(52)의 워터펌프(56)를 오프(OFF)시키도록 구성된다.On the other hand, the control unit 70, when the temperature of the battery 40 input from the battery temperature sensor 74 exceeds the preset reference battery temperature, the water pump 56 of the battery-side cooling water circulation line 52 Is configured to turn OFF.

따라서, 배터리(40)의 온도가 기준배터리온도를 초과할 시에, 배터리(40)의 예열을 제한한다. 이로써, 배터리(40)의 예열로 인한 배터리(40)의 과열을 방지한다.Thus, when the temperature of the battery 40 exceeds the reference battery temperature, preheating of the battery 40 is limited. This prevents overheating of the battery 40 due to preheating of the battery 40.

여기서, 제어부(70)는, 배터리온도 감지센서(74)에서 입력된 배터리(40)의 온도가 기준배터리온도 이하로 저하될 시에는, 배터리측 냉각수순환라인(52)의 워터펌프(56)를 다시 온(ON)시키도록 구성된다. 따라서, 배터리(40)의 예열이 재개될 수 있도록 구성된다.Here, the controller 70, when the temperature of the battery 40 input from the battery temperature sensor 74 is lowered below the reference battery temperature, the controller 70 turns off the water pump 56 of the battery-side cooling water circulation line 52. Configured to be ON again. Thus, the preheating of the battery 40 can be resumed.

한편, 제어부(70)는, 배터리측 냉각수순환라인(52) 또는 배터리온도 감지센서(74)로부터 입력된 냉각수 온도 또는 배터리 온도에 비례하여 배터리측 냉각수순환라인(52)의 워터펌프(56)를 능동적으로 가변제어할 수도 있다.Meanwhile, the controller 70 controls the water pump 56 of the battery side coolant circulation line 52 in proportion to the coolant temperature or the battery temperature input from the battery side coolant circulation line 52 or the battery temperature sensor 74. Actively variable control can also be used.

여기서, 냉각수온도 감지센서(72)는, 배터리측 냉각수순환라인(52)상에 설치되어 있되, 배터리(40)의 상류측 배터리측 냉각수순환라인(52)부분에 설치되는 것이 좋다. 이는, 배터리(40)로 도입되는 냉각수의 온도를 감지하기 위함이다. Here, the coolant temperature sensor 72 is provided on the battery-side cooling water circulation line 52, it is preferably installed in the upstream battery-side cooling water circulation line 52 of the battery 40. This is to sense the temperature of the coolant introduced into the battery 40.

이와 같은 구조를 갖는 본 발명의 열관리 시스템에 의하면, 히터코어측 냉각수순환라인(30)의 냉각수 열을, 배터리측 냉각수순환라인(52)의 냉각수로 전달받은 다음, 전달받은 냉각수로 배터리(40)를 예열하는 구조이므로, 히터코어측 냉각수순환라인(30)의 냉각수 열로 배터리(40)를 직접 예열하는 종래 기술과 달리, 배터리(40)를 간접적으로 예열할 수 있다.According to the thermal management system of the present invention having such a structure, the coolant heat of the heater core side coolant circulation line 30 is transferred to the coolant of the battery side coolant circulation line 52 and then the battery 40 is transferred to the coolant. Since the preheating structure, unlike the prior art that directly preheats the battery 40 by the coolant heat of the heater core side coolant circulation line 30, it is possible to indirectly preheat the battery 40.

또한, 배터리(40)를 간접적으로 예열할 수 있는 구조이므로, 배터리(40)를 직접 예열하는 것에 따른 배터리(40)의 과열 우려를 방지할 수 있고, 이로써, 배터리(40)의 과열로 인한 배터리의 성능저하와, 손상 및 수명 단축 현상을 미연에 방지할 수 있다.In addition, since the battery 40 can be indirectly preheated, the risk of overheating of the battery 40 due to the direct preheating of the battery 40 can be prevented, whereby the battery due to overheating of the battery 40 can be prevented. The performance degradation, damage and shortening of the lifespan can be prevented in advance.

또한, 냉각수의 온도에 따라 배터리측 냉각수순환라인(52)의 워터펌프(56)를 가변제어하여, 배터리(40)로 순환되는 냉각수의 유량을 제어할 수 있는 구조이므로, 냉각수 온도로 인한 배터리(40)의 과도한 예열과, 그로 인한 배터리(40)의 과열을 원천적으로 방지할 수 있다.In addition, since the water pump 56 of the battery-side cooling water circulation line 52 is variably controlled according to the temperature of the cooling water, the flow rate of the cooling water circulated to the battery 40 can be controlled. Excessive preheating of 40 and, consequently, overheating of the battery 40 can be prevented at the source.

또한, 배터리(40)의 과열을 원천적으로 방지할 수 있으므로, 배터리의 과열로 인한 배터리의 성능저하와, 손상 및 수명 단축 현상을 방지할 수 있다.In addition, since the overheating of the battery 40 can be prevented at the source, degradation of the battery, damage, and shortening of the life due to the overheating of the battery can be prevented.
