본 발명은 하이브리드 전기 차량용 LDC/MCU/인버터 어셈블리의 통합형 냉각장치에 관한 것으로서, 더욱 상세하게는 하이브리드 전기 차량에 장착되는 MCU 및 인버터의 상측 부품과 LDC의 하측 부품 사이를 일체로 연결하는 냉각핀을 포함하여 구성된 LDC/MCU/인버터 어셈블리의 냉각장치에 관한 것이다.The present invention relates to an integrated cooling device of an LDC / MCU / inverter assembly for a hybrid electric vehicle, and more particularly, to a cooling fin integrally connecting an upper part of an MCU and an inverter mounted on a hybrid electric vehicle and a lower part of an LDC. It relates to a cooling device of the LDC / MCU / inverter assembly configured to include.

일반적으로 넓은 의미의 하이브리드 차량은 서로 다른 두 종류 이상의 동력원을 효율적으로 조합하여 차량을 구동시키는 것을 의미하나, 대부분의 경우는 연료를 사용하는 엔진과 배터리의 전력으로 구동되는 전기모터에 의해 구동력을 얻는 차량을 의미하며, 이를 하이브리드 전기 차량, 즉 HEV(hybrid electric vehicle)라 부르고 있다.In general, a hybrid vehicle in a broad sense means driving a vehicle by efficiently combining two or more different power sources, but in most cases, a driving force is obtained by an electric motor driven by a fuel-powered engine and a battery. A vehicle, which is called a hybrid electric vehicle, that is, a hybrid electric vehicle (HEV).

이러한 하이브리드 전기 차량에는 전기모터의 구동전력을 제공하는 고전압 배터리가 필수적으로 장착되는데, 상기 배터리는 차량 운행 중에 충/방전을 반복하면서 필요한 전력을 공급하게 된다. Such a hybrid electric vehicle is essentially equipped with a high-voltage battery that provides the driving power of the electric motor, the battery will supply the necessary power while repeatedly charging / discharging while driving the vehicle.

하이브리드 전기 차량에서 고전압 배터리 관련 시스템은 여러 개의 단품이 하나로 조립된 통합 구조물로 설계되어 차량 실내(뒷좌석 시트 밑)나 트렁크룸 내에 장착되는데, 배터리 관련 시스템의 단품으로는 배터리, LDC(Low DC-DC Converter), MCU(Motor Control Unit), 인버터 등이 있다. In hybrid electric vehicles, the high-voltage battery-related system is designed as an integrated structure in which several units are assembled together and mounted inside the vehicle interior (under the rear seat) or in the luggage compartment.The single unit of the battery-related system is battery, low DC-DC. Converter, MCU (Motor Control Unit), and Inverter.

특히, LDC 및 MCU, 인버터는 일체용 브라켓에 의하여 하나의 어셈블리로 조립되는 바, 어셈블리의 조립상태는 첨부한 도 4와 도 5에 도시한 바와 같다.In particular, the LDC, MCU, and inverter are assembled into one assembly by an integrated bracket, and the assembly state of the assembly is as shown in FIGS. 4 and 5.

도 4는 어셈블리에서 각 단품의 배치상태를 보여주는 정면도이고, 도 5는 그 측면도이다.Figure 4 is a front view showing the arrangement of each unit in the assembly, Figure 5 is a side view thereof.

이에 도시한 바와 같이, 어셈블리(1)에서 MCU(2)와 인버터(3)는 상측에, LDC(4)는 그 하측에 배치되어, 상측 부품(2,3)과 하측 부품(4)이 일체용 브라켓(5)에 의하여 상호 연결 및 조립되고, 특히 각 부품은 작동시에 열이 발생하는 발열부품이므로, 조립된 상태에서 냉각팬(6)을 이용해 상측 부품(2,3)과 하측 부품(4) 간의 공간을 통해 공기를 강제 통풍시키는 냉각을 실시하고 있다.As shown in the figure, in the assembly 1, the MCU 2 and the inverter 3 are disposed on the upper side, and the LDC 4 is disposed on the lower side thereof so that the upper component 2, 3 and the lower component 4 are integrated. The parts are interconnected and assembled by the bracket 5, and in particular, each part is a heat-generating part that generates heat during operation, so that the upper part (2, 3) and the lower part (using the cooling fan 6 in the assembled state) 4) Cooling is performed to force air through the space between the livers.

즉, LDC(4) 상면의 방열판(4a)에 냉각핀(4b)을 돌출 형성하고, 이에 마주보는 MCU(2) 및 인버터(3) 하면의 방열판(2a,3a)에 각각 냉각핀(2b,3b)을 돌출 형성하여, 상측 부품의 냉각핀(2b,3b)과 하측 부품의 냉각핀(4b)이 일정 간격 이격된 상태에서 서로 마주보게 배치한 뒤, 상측 부품의 냉각핀(2b,3b)과 하측 부품의 냉각핀(4b) 사이에 냉각팬(6)으로 화살표 방향의 공기를 강제 통풍시켜 냉각을 한다.That is, the cooling fins 4b protrude from the heat sink 4a on the upper surface of the LDC 4, and the cooling fins 2b and 3 are respectively disposed on the heat sinks 2a and 3a on the lower surface of the MCU 2 and the inverter 3 facing each other. 3b) is formed to protrude, and the cooling fins 2b and 3b of the upper part and the cooling fins 4b of the lower part are disposed to face each other in a state spaced apart from each other, and then the cooling fins 2b and 3b of the upper part. The air in the direction of the arrow is forcedly cooled by the cooling fan 6 between the cooling fins 4b of the lower part and cooled.

도시한 바와 같이 종래에는 상측 부품인 MCU(2) 및 인버터(3)와 하측 부품인 LDC(4)가 각각 별도로 제작되어 각각의 냉각핀(2b,3b,4b)을 가지고 있는 구조이며, 상하 부품 간 냉각핀을 이격시킨 상태에서 상측 부품(2,3)과 하측 부품(4)을 일체용 브라켓(5)을 사용해 결합하고 있는 구조로 되어 있다.As shown in the prior art, the upper component MCU 2 and inverter 3 and the lower component LDC 4 are manufactured separately and have cooling fins 2b, 3b, and 4b, respectively. The upper component 2, 3 and the lower component 4 are joined together using the integrated bracket 5 while the intercooling fins are spaced apart.

그러나, 상측 부품과 하측 부품의 면적이 비슷함에도 각 부품이 냉각핀을 별도로 구비하고 있는 바, 예컨대 MCU 및 인버터와 LDC가 각각 독립적인 냉각핀을 장착하고 있으므로, 한쪽이 동작하고(발열하고) 나머지 한쪽이 동작하지 않을 때(발열하지 않을 때) 서로 열이 전달될 수 없는 구조이다.However, even though the upper and lower parts have similar areas, each part has a separate cooling fin. For example, since the MCU, inverter, and LDC each have independent cooling fins, one side operates (heats) and the other It is a structure in which heat cannot be transferred to each other when one side does not work (not generate heat).

또한 각각 냉각핀을 구비한 독립된 부품을 일체용 브라켓으로 조립하여 장착 하는 바, 조립성 및 장착성 측면에서 미흡한 점이 있고, 브라켓 사용으로 인한 설계 제약의 문제, 독립된 부품 설계 및 개발로 인한 개발비용 증가 문제 등이 지적되고 있다. In addition, as the independent parts with cooling fins are assembled by mounting brackets, they are inadequate in terms of assembling and mounting, and there are problems of design constraints due to the use of brackets and increased development costs due to independent parts design and development. Etc. are pointed out.

따라서, 본 발명은 상기와 같은 문제점을 해결하기 위하여 발명한 것으로서, 강제 통풍에 의한 냉각작용과 더불어 냉각핀에 의한 좀더 효율적인 부품 냉각이 가능해지는 LDC/MCU/인버터 어셈블리의 냉각장치를 제공하는데 그 목적이 있다.Accordingly, the present invention has been invented to solve the above problems, to provide a cooling device of the LDC / MCU / inverter assembly that is capable of cooling the component by the cooling fins in addition to the cooling action by forced ventilation. There is this.

또한 종래와 같은 별도의 일체용 브라켓이 불필요하고, 어셈블리 구조를 더욱 간단하게 할 수 있는 LDC/MCU/인버터 어셈블리의 냉각장치를 제공하는데 그 목적이 있다.It is also an object of the present invention to provide a cooling device of an LDC / MCU / inverter assembly that does not require a separate integrated bracket as in the related art and can simplify the assembly structure.

또한 일체용 브라켓의 삭제에 의해 조립성 및 장착성 측면에서 좀더 유리해지고, 브라켓 사용으로 인한 설계 제약의 문제가 해결되며, 통합된 부품 설계 및 개발에 의해 비용을 줄일 수 있는 LDC/MCU/인버터 어셈블리의 냉각장치를 제공하는데 그 목적이 있다.In addition, the elimination of the integrated bracket provides more advantages in terms of assembly and mounting, solves the design constraints caused by the use of the bracket, and reduces the cost of integrated component design and development. The purpose is to provide a cooling device.

이하, 첨부한 도면을 참조하여 본 발명을 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

상기한 목적을 달성하기 위해, 본 발명은, 하이브리드 전기 차량에 장착되는 LDC/MCU/인버터 어셈블리의 냉각장치에 있어서,In order to achieve the above object, the present invention, in the cooling device of the LDC / MCU / inverter assembly mounted on a hybrid electric vehicle,

상기 LDC, MCU 및 인버터 중에서 상측에 배치되는 부품과 하측에 배치되는 부품 사이에 형성된 냉각핀을 포함하되, 상기 상측 부품의 냉각핀과 하측 부품의 냉각핀이 상하 간에 연결되어, 상기 상측 부품과 하측 부품이 상기 냉각핀에 의해 상호 연결 및 고정된 구조로 되어 있는 것을 특징으로 하는 하이브리드 전기 차량용 LDC/MCU/인버터 어셈블리의 통합형 냉각장치를 제공한다.It includes a cooling fin formed between the components disposed on the upper side and the lower portion of the LDC, MCU and inverter, the cooling fin of the upper component and the cooling fin of the lower component is connected between the upper and lower, the upper component and the lower side An integrated cooling device of an LDC / MCU / inverter assembly for a hybrid electric vehicle is characterized in that the parts are interconnected and fixed by the cooling fins.

여기서, 상기 각 냉각핀의 표면은 와류 형성을 위한 다수개의 요홈이 형성된 구조로 되어 있는 것을 특징으로 한다.Here, the surface of each cooling fin is characterized in that the structure is formed with a plurality of grooves for vortex formation.

이하, 첨부한 도면을 참조하여 본 발명에 대해 더욱 상세히 설명하면 다음과 같다.Hereinafter, the present invention will be described in more detail with reference to the accompanying drawings.

첨부한 도 1은 본 발명에 따른 냉각장치가 적용된 LDC/MCU/인버터 어셈블리의 정면도이고, 도 2는 본 발명에 따른 냉각장치가 적용된 LDC/MCU/인버터 어셈블리의 측면도이며, 도 3은 본 발명에 따른 냉각장치의 냉각핀 표면 구조를 도시한 사시도이다.1 is a front view of the LDC / MCU / inverter assembly to which the cooling device according to the present invention is applied, and FIG. 2 is a side view of the LDC / MCU / inverter assembly to which the cooling device according to the present invention is applied, and FIG. It is a perspective view showing the surface structure of the cooling fins of the cooling apparatus.

도 1과 도 2에 도시한 바와 같이, 어셈블리(11)의 상측 부품인 MCU(12) 및 인버터(13)와 하측 부품인 LDC(14)의 냉각을 위하여 구성되는 본 발명의 냉각장치는 상기 상측 부품(12,13)과 상기 하측 부품(14) 사이에 일체로 연결되는 공용 냉각핀(15,16)을 포함한다.1 and 2, the cooling device of the present invention configured for cooling the MCU 12 and the inverter 13, which is the upper component of the assembly 11, and the LDC 14, which is the lower component, is the upper side. Common cooling fins 15, 16 are integrally connected between the components 12, 13 and the lower component 14.

즉, 상측 부품(12,13)과 하측 부품(14)의 방열판(12a,13a,14a)으로부터 돌출 형성된 냉각핀(15,16)을 상측 부품과 하측 부품 간에 일체로 연결하여 통합 구성하며, 상측 부품(12,13)과 하측 부품(14)이 상기 공용 냉각핀(15,16)에 의해 서로 연 결된 구조로 되어 있는 것이다.That is, the upper and lower parts 12 and 13 and the cooling fins 15 and 16 protruding from the heat sinks 12a, 13a and 14a of the lower part 14 are integrally connected between the upper part and the lower part to be integrated. The components 12 and 13 and the lower component 14 are connected to each other by the common cooling fins 15 and 16.

이와 같이 공용 냉각핀(15,16)으로 상측 부품(12,13)과 하측 부품(14)을 연결하고, 상측 부품과 하측 부품의 냉각핀(15,15) 사이로 종래와 같이 냉각팬(17)을 이용해 화살표 방향으로 공기를 강제 통풍시키게 된다.In this way, the upper parts 12 and 13 and the lower part 14 are connected to each other by the common cooling fins 15 and 16, and the cooling fan 17 as in the related art is provided between the upper and lower parts of the cooling fins 15 and 15. Forced air in the direction of the arrow.

또한 도시한 바와 같이 공용 냉각핀(15,16)을 설치한 상태에서 상측 부품(12,13)과 하측 부품(14) 사이에 냉각핀 바깥쪽으로 연결상태를 보조하는 보조 연결부재(18)를 설치할 수도 있다.In addition, the auxiliary connecting member 18 is installed between the upper parts 12 and 13 and the lower part 14 to assist the connection state to the outside of the cooling fin in the state where the common cooling fins 15 and 16 are installed. It may be.

그리고, 본 발명의 바람직한 실시예에서, 냉각핀(15,16)의 표면에는 도 3에 나타낸 바와 같이 다수개의 요홈(15a,16a)을 형성하는 바, 이러한 요홈 형성에 의해 냉각핀의 냉각 효율을 향상시킬 수 있다.And, in a preferred embodiment of the present invention, as shown in Figure 3 on the surface of the cooling fins (15, 16) to form a plurality of grooves (15a, 16a), by forming such grooves to reduce the cooling efficiency of the cooling fins Can be improved.

즉, 종래의 냉각핀은 매끄러운 표면을 가지고 있어서 표면을 타고 흐르는 공기가 층을 형성하므로 냉각이 비효율적으로 일어나나, 본 발명에서와 같이 냉각핀(15,16) 표면에 골프공의 홈처럼 다수개의 요홈(15a,16a)을 형성시켜 주면, 상기 요홈에 의해 와류가 발생하고, 이에 따라 표면을 타고 흐르는 공기 유동이 난류를 형성하게 되면서 냉각 효율이 좀더 높아질 수 있게 된다.That is, the conventional cooling fin has a smooth surface, so that the air flowing through the surface forms a layer, so that cooling occurs inefficiently, as in the present invention, a plurality of cooling fins (15, 16) like a groove of a golf ball on the surface When the grooves 15a and 16a are formed, vortices are generated by the grooves, and as a result, the air flow flowing through the surface forms turbulent flow, thereby further increasing the cooling efficiency.

결국, 본 발명의 냉각장치에서는 상측 부품(12,13)과 하측 부품(14)이 냉각핀(15,16)에 의해 일체로 연결된 구조로 되어 있으므로, 상측 부품과 하측 부품 중에 어느 한쪽이 동작하고(발열하고) 나머지 한쪽이 동작하지 않을 때(발열하지 않을 때) 동작하는 쪽에서 동작하지 않는 쪽으로 열이 전달될 수 있는 바, 이는 강제 통풍에 의한 냉각작용과 더불어 좀더 효율적인 부품 냉각을 가능하게 한다.As a result, in the cooling apparatus of the present invention, since the upper parts 12 and 13 and the lower part 14 are integrally connected by the cooling fins 15 and 16, either one of the upper part and the lower part operates. Heat can be transferred from the operating side to the non-operating side when the other side (heats up) does not work (when it does not generate heat), which together with cooling by forced ventilation allows for more efficient component cooling.

또한 냉각핀(15,16)에 의해 상측 부품(12,13)과 하측 부품(14)이 일체로 연결되므로 종래와 같은 별도의 일체용 브라켓이 불필요하고, 브라켓이 아닌 냉각핀에 의해 양측의 부품을 고정시키므로 구조를 더욱 간단하게 할 수 있다.In addition, since the upper and lower parts 12 and 13 and the lower part 14 are integrally connected by the cooling fins 15 and 16, separate integrated brackets are not required as in the related art, and components on both sides are provided by cooling fins instead of brackets. The structure can be made simpler by fixing.

또한 상측 부품(12,13)과 하측 부품(14)을 중간의 공용 냉각핀(15,16)으로 연결된 일체형으로 제작하므로 일체용 브라켓을 사용하여 조립하는 것에 비해 조립성 및 장착성 측면에서 좀더 유리해지고, 일체형 브라켓이 삭제되므로 브라켓 사용으로 인한 설계 제약의 문제가 해결되며, 통합된 부품 설계 및 개발에 의해 비용을 줄일 수 있는 장점이 있게 된다.In addition, since the upper part (12, 13) and the lower part (14) is manufactured in one piece connected by the common cooling fins (15, 16) in the middle, it is more advantageous in terms of assemblability and mounting than the assembly using the integrated bracket. Since the integrated bracket is eliminated, the problem of design constraints due to the use of the bracket is solved, and the cost can be reduced by integrated component design and development.

이상에서 설명한 바와 같이, 본 발명에 따른 하이브리드 전기 차량용 LDC/MCU/인버터 어셈블리의 통합형 냉각장치에 의하면, 상측 부품과 하측 부품을 연결하는 냉각핀으로 구성되므로, 상측 부품과 하측 부품 중에 어느 한쪽이 동작하고(발열하고) 나머지 한쪽이 동작하지 않을 때(발열하지 않을 때) 동작하는 쪽에서 동작하지 않는 쪽으로 열이 전달될 수 있는 바, 이는 강제 통풍에 의한 냉각작용과 더불어 좀더 효율적인 부품 냉각을 가능하게 한다.As described above, according to the integrated cooling device of the LDC / MCU / inverter assembly for a hybrid electric vehicle according to the present invention, since it is composed of cooling fins connecting the upper part and the lower part, either one of the upper part and the lower part is operated. And heat can be transferred from the operating side to the non-operating side when the other side is not working (heating), which allows for more efficient component cooling along with forced cooling. .

또한 종래와 같은 별도의 일체용 브라켓이 불필요하고, 브라켓이 아닌 냉각핀에 의해 양측의 부품을 고정시키므로 구조를 더욱 간단하게 할 수 있다.In addition, a separate integral bracket as in the prior art is not necessary, and the structure is further simplified since the components on both sides are fixed by the cooling fin instead of the bracket.

또한 일체용 브라켓을 사용하여 조립하는 것에 비해 조립성 및 장착성 측면에서 좀더 유리해지고, 브라켓 사용으로 인한 설계 제약의 문제가 해결되며, 통합 된 부품 설계 및 개발에 의해 비용을 줄일 수 있는 장점이 있게 된다.In addition, it is more advantageous in terms of assembly and mounting than assembly using an integrated bracket, solves the problem of design constraints due to the use of the bracket, and reduces the cost by integrated component design and development .
