Description

전기자동차용 OBC 모듈{OBC MODULE FOR ELECTRIC VEHICLE}[0001] OBC MODULE FOR ELECTRIC VEHICLE [0002] OBC MODULE FOR ELECTRIC VEHICLE [

본 발명은 방열 효율이 향상된 전기자동차용 OBC 모듈에 관한 것이다. The present invention relates to an OBC module for an electric vehicle having improved heat dissipation efficiency.

최근 친환경 차량에 대한 수요가 높아지면서 각종 친환경 차량이 개발되어 사용되고 있다. 대표적인 예로는 전기를 차량의 구동원으로 사용하는 하이브리드 자동차나 배터리만을 구동원으로 이용하는 전기모터 자동차 등이 있다. Recently, as demand for environmentally friendly vehicles has increased, various environmentally friendly vehicles have been developed and used. Typical examples include a hybrid vehicle using electricity as the driving source of the vehicle or an electric motor vehicle using only the battery as the driving source.

이러한 전기자동차들은 배터리를 연료원으로 사용하고, 모터를 구동원으로 사용한다. 따라서, 전기자동차 내에는 차량에 내장된 배터리를 충전하기 위한 차량 탑재형 충전기(OBC: On Board Charger)가 탑재된다. These electric vehicles use the battery as the fuel source and the motor as the driving source. Accordingly, an on-board charger (OBC: On Board Charger) for charging a battery built in the vehicle is mounted in the electric vehicle.

이러한 OBC는 부피를 감소시키기 위해 각종 부품들이 하우징 내에 밀집되어 있는 형태의 모듈로 제공된다. 따라서, 배터리의 충전시 부품들에서 발생하는 열원이 하우징 내에 집중적으로 모이게 되어 하우징 내부의 온도가 상승하는 문제가 있다. The OBC is provided as a module in which various components are packed in a housing in order to reduce the volume. Accordingly, there is a problem that the heat source generated in the parts when the battery is charged concentrates in the housing, thereby raising the temperature inside the housing .

특히, 하우징 내에는 전력밀도가 큰 고전압 전해 커패시터가 배치되는데, 이 전해 커패시터의 경우 온도에 매우 민감하여 하우징 내의 온도가 상승할 경우 전해액이 감소하여 커패시터의 수명이 줄어드는 문제가 있다. In particular, a high-voltage electrolytic capacitor having a high power density is disposed in the housing. In the case of the electrolytic capacitor, the electrolytic capacitor is susceptible to temperature, so that when the temperature in the housing rises, the electrolytic solution decreases and the life of the capacitor is reduced.

따라서, 하우징 내부의 열원 및 전해 커패시터 자체에서 발생하는 열원을 빠르게 방출시켜주어야만 한다. Therefore, the heat source inside the housing and the heat source generated from the electrolytic capacitor itself must be quickly released.

본 발명의 과제는 커패시터에서 발생하는 열원을 보다 빠르게 방출할 수 있도록 구조를 개선함으로써, 커패시터의 수명이 증대된 전기자동차용 OBC 모듈을 제공함에 있다. An object of the present invention is to provide an OBC module for an electric vehicle in which the lifetime of a capacitor is increased by improving the structure so that a heat source generated in a capacitor can be discharged more quickly.

상기의 과제를 달성하기 위한 본 발명에 따른 전기자동차용 OBC 모듈은 전기자동차용 배터리의 충전을 위한 것으로, OBC 하우징과, PCB 기판, 및 커패시터를 포함한다. OBC 하우징 은 내부에 수용공간을 가지며 상방이 개구된 케이스와, 케이스를 개폐하는 덮개부를 구비한다. PCB 기판은 OBC 하우징의 수용공간에 배치된다. 커패시터는 OBC 하우징의 수용공간에 배치되어 PCB 기판에 솔더링되고, 상측면이 덮개부와 맞닿게 형성된다. 그리고, OBC 하우징의 덮개부는 커패시터와 맞닿는 면의 반대편에 복수의 방열핀을 더 포함하는 것을 특징으로 한다. According to an aspect of the present invention, there is provided an OBC module for an electric vehicle for charging an electric vehicle battery, the OBC module including a PCB substrate, and a capacitor. The OBC housing is provided with a case having a housing space inside and opening upward, and a lid part for opening and closing the case. The PCB substrate is placed in the receiving space of the OBC housing. The capacitor is disposed in the receiving space of the OBC housing and is soldered to the PCB substrate, and the upper side is formed to abut the lid part. The lid of the OBC housing further includes a plurality of radiating fins on the opposite side of the surface contacting the capacitor.

본 발명에 따르면, 발열기기인 커패시터가 OBC 하우징과 맞닿게 형성됨에 따라, 전도에 의해 커패시터에서 발생하는 열원을 외부로 방출할 수 있게 된다. According to the present invention, since the capacitor, which is a heating device, is formed to abut the OBC housing, the heat source generated in the capacitor can be discharged to the outside by conduction.

또한, 커패시터와 맞닿는 OBC 하우징의 덮개부에 방열핀을 형성함에 따라, 커패시터에서 발생하는 열원을 보다 빠르게 방출할 수 있게 되어 커패시터의 수명을 증대시킬 수 있게 된다. In addition, since the radiating fin is formed on the lid of the OBC housing which contacts the capacitor, the heat source generated from the capacitor can be discharged more quickly, so that the lifetime of the capacitor can be increased.

아울러, 커패시터와 OBC 하우징 사이에 열 전도성 소재의 방열패드를 장착함에 따라, 커패시터에서 발생하는 열원을 보다 빠르게 방출할 수 있게 되어 커패시터의 수명을 증대시킬 수 있게 된다.In addition, since a heat-radiating pad of a thermally conductive material is mounted between the capacitor and the OBC housing, the heat source generated from the capacitor can be discharged more quickly, thereby increasing the lifetime of the capacitor.

이하 첨부된 도면을 참조하여, 바람직한 실시예에 따른 전기자동차용 OBC 모듈에 대해 상세히 설명하면 다음과 같다. 여기서, 동일한 구성에 대해서는 동일부호를 사용하며, 반복되는 설명, 발명의 요지를 불필요하게 흐릴 수 있는 공지 기능 및 구성에 대한 상세한 설명은 생략한다. 발명의 실시형태는 당업계에서 평균적인 지식을 가진 자에게 본 발명을 보다 완전하게 설명하기 위해서 제공되는 것이다. 따라서, 도면에서의 요소들의 형상 및 크기 등은 보다 명확한 설명을 위해 과장될 수 있다. Hereinafter, an OBC module for an electric vehicle according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying drawings. Here, the same reference numerals are used for the same components, and repeated descriptions and known functions and configurations that may obscure the gist of the present invention will not be described in detail. Embodiments of the invention are provided to more fully describe the present invention to those skilled in the art. Accordingly, the shapes and sizes of the elements in the drawings and the like can be exaggerated for clarity.

도 1은 본 발명의 일 실시예에 따른 전기자동차용 OBC 모듈의 단면도이다.1 is a cross-sectional view of an OBC module for an electric vehicle according to an embodiment of the present invention.

도 1에 도시된 바와 같이, 전기자동차 OBC(On Board Charger) 모듈(100)은 전기자동차용 배터리의 충전을 위한 것으로, OBC 하우징(110)과, PCB 기판(120), 및 커패시터(130)를 포함한다. 1, an electric vehicle OBC (On Board Charger) module 100 is for charging an electric vehicle battery, and includes an OBC housing 110, a PCB substrate 120, and a capacitor 130 .

OBC 하우징(110)은 내부에 수용공간을 가지며 상방이 개구된 케이스(111)와, 케이스(111)를 개폐하는 덮개부(112)를 구비한다. 여기서, OBC 하우징(110)의 소재는 한정되지 않으나, 알루미늄, 구리 등과 같이 열전도가 좋은 금속 소재로 형성되는 것이 바람직하다. The OBC housing 110 includes a case 111 having a receiving space therein and having an upper opening and a lid 112 for opening and closing the case 111. Here, although the material of the OBC housing 110 is not limited, it is preferable that the OBC housing 110 is formed of a metal material having good thermal conductivity such as aluminum or copper.

PCB 기판(120)은 OBC 하우징(110)의 수용공간에 배치된다. PCB 기판(120)은 일면 또는 양면에 도체 패턴이 있는 배선판으로, OBC 모듈의 각 소자들이 PCB 기판(120) 상에 전기적으로 연결될 수 있다. The PCB substrate 120 is disposed in the receiving space of the OBC housing 110. The PCB substrate 120 may be a wiring board having a conductor pattern on one side or both sides thereof, and each element of the OBC module may be electrically connected to the PCB substrate 120.

커패시터(130)는 OBC 하우징(110)의 수용공간에 배치되어 PCB 기판(120)에 솔더링되고, 상측면이 덮개부(112)와 맞닿게 형성된다. 여기서, 커패시터(130)는 고전압 전해 커패시터로 형성될 수 있다. The capacitor 130 is disposed in the housing space of the OBC housing 110 and is soldered to the PCB substrate 120 and the upper side thereof is in contact with the lid 112. Here, the capacitor 130 may be formed of a high-voltage electrolytic capacitor.

이처럼 커패시터(130)의 상측면이 덮개부(112)와 맞닿게 형성됨에 따라, 전도에 의한 방열효과를 얻을 수 있게 된다. 즉, 덮개부(112)는 방열판 역할을 하며, 커패시터(130)에서 발생하는 열원은 덮개부(112)를 통해 OBC 하우징(110)의 외부로 방출할 수 있게 되는 것이다. Since the upper surface of the capacitor 130 is formed to abut the lid portion 112, heat dissipation due to conduction can be obtained. That is, the lid part 112 serves as a heat sink, and a heat source generated from the capacitor 130 can be discharged to the outside of the OBC housing 110 through the lid part 112.

특히, 커패시터(130)가 전력밀도가 큰 고전압 전해 커패시터로 형성된 경우, 온도가 상승하게 되면 커패시터(130) 내부의 전해액이 마르게 되어 용량이 감소하게 되고 수명이 줄어들게 된다. 따라서, 상기와 같이 커패시터(130)에서 발생하는 열원을 덮개부(112)를 통해 방출하면 커패시터(130)의 수명을 증대시킬 수 있게 된다. In particular, when the capacitor 130 is formed of a high-voltage electrolytic capacitor having a high power density, if the temperature rises, the electrolyte in the capacitor 130 becomes dry and the capacity is reduced and the service life is reduced. Therefore, if the heat source generated in the capacitor 130 is discharged through the lid unit 112 as described above, the life of the capacitor 130 can be increased.

한편, OBC 하우징(110)의 덮개부(112)는 커패시터(130)와 맞닿는 면의 반대편에 복수의 방열핀(112a)을 더 포함할 수 있다. 여기서, 방열핀(112a)은 공기의 접촉면적을 넓혀 냉각효율을 증대시켜주기 위한 것으로, 알루미늄, 구리 등과 같이 열전도가 좋은 금속 소재로 형성될 수 있다. The cover portion 112 of the OBC housing 110 may further include a plurality of radiating fins 112a on the opposite side of the surface contacting the capacitor 130. [ Here, the radiating fin 112a is provided to increase the cooling efficiency by widening the contact area of air, and may be formed of a metal material having good thermal conductivity such as aluminum, copper, or the like.

이처럼 덮개부(112)에 방열핀(112a)이 형성됨에 따라, 냉각효율이 증대되어 커패시터(130)에서 발생하는 열원을 보다 빠르게 방출할 수 있게 된다.As the radiating fin 112a is formed on the cover 112, the cooling efficiency is increased, and the heat source generated in the capacitor 130 can be discharged more quickly.

그리고, 덮개부(112)는 방열핀(112a)이 형성된 부위가 커패시터(130)가 배치된 방향으로 오목하게 들어간 단차(미도시)를 갖도록 형성될 수 있다. 이는, 케이스(111)의 높이가 높아 덮개부(112)와 커패시터(130)가 맞닿지 않을 경우, 단차를 주어 덮개부(112)와 커패시터(130)를 접촉시키기 위함이다. The lid portion 112 may be formed to have a stepped portion (not shown) where the portion where the radiating fin 112a is formed is recessed in the direction in which the capacitor 130 is disposed. This is to contact the lid part 112 and the capacitor 130 with a step difference when the lid part 112 and the capacitor 130 are not in contact with each other because the height of the case 111 is high.

도 2는 본 발명의 다른 실시예에 따른 전기자동차용 OBC 모듈의 단면도이다.2 is a cross-sectional view of an OBC module for an electric vehicle according to another embodiment of the present invention.

도 2에 도시된 바와 같이, 전기자동차용 OBC 모듈(200)은 커패시터(130)와 덮개부(112) 사이에 배치된 방열패드(140)를 더 포함할 수 있다. 보다 구체적으로, 방열패드(140)는 OBC 하우징(110)의 수용공간에 배치되며, 하측면이 커패시터(130)와 맞닿게 형성되고 상측면이 덮개부(112)와 맞닿게 형성된다. 이처럼 커패시터(130)와 덮개부(112) 사이에 방열패드(140)가 장착됨에 따라, 커패시터(130)에서 발생하는 열원을 보다 빠르게 방출할 수 있게 된다.2, the OBC module 200 for an electric vehicle may further include a heat radiating pad 140 disposed between the capacitor 130 and the lid portion 112. More specifically, the heat radiating pad 140 is disposed in the receiving space of the OBC housing 110, the lower surface thereof is formed to abut the capacitor 130, and the upper surface thereof is abutted against the lid part 112. As the heat dissipation pad 140 is mounted between the capacitor 130 and the lid 112, the heat source generated by the capacitor 130 can be discharged more quickly.

방열패드(140)는 열 전도성 소재로 점착성을 가지며, 덮개부(112)에 탈착 가능하게 형성될 수 있다. 여기서, 방열패드(140)는 열 전도성 및 점착성을 갖는 것이라면 어느 것이나 가능하나, 실리콘 소재로 형성되는 것이 바람직하다. The heat radiating pad 140 may be made of a thermally conductive material and may be detachably attached to the lid 112. Here, the heat-radiating pad 140 may be any material having thermal conductivity and adhesiveness, but is preferably formed of a silicon material.

이처럼 방열패드(140)가 점착성을 갖도록 형성됨에 따라 별도의 체결부재 없이도 덮개부(112)에 고정시킬 수 있으며, 덮개부(112)에 반복적으로 탈착 할 수 있게 된다. Since the heat dissipation pad 140 is formed to have adhesiveness, the heat dissipation pad 140 can be fixed to the lid 112 without additional fastening members, and can be repeatedly attached to and detached from the lid 112.

한편, 케이스(111)의 내부에는 케이스(111)의 바닥면과 마주보도록 배치된 구획판(111a)이 설치될 수 있다. 그리고, 구획판(111a)의 상부에는 PCB 기판(120) 및 커패시터(130)가 배치될 수 있다. Meanwhile, a partition plate 111a disposed so as to face the bottom surface of the case 111 may be installed inside the case 111. A PCB substrate 120 and a capacitor 130 may be disposed above the partition plate 111a.

이처럼 구획판(111a)의 상부에 PCB 기판(120) 및 커패시터(130)가 배치됨에 따라 OBC 하우징(110)의 하부에서 전달되는 열원, 예를 들어 구동모터 등에서 발생하는 열원이 커패시터(130)로 직접 전달되지 않으므로 커패시터(130)를 보호할 수 있게 된다. Since the PCB substrate 120 and the capacitor 130 are disposed on the upper part of the partition plate 111a, a heat source generated from a heat source such as a driving motor or the like, which is transmitted from the lower portion of the OBC housing 110, So that the capacitor 130 can be protected.

그리고, 구획판(111a)의 하부에는 일정 공간이 형성되므로, 이 공간에 구동모터를 냉각시키기 위한 냉각유로를 배치시키게 되면 냉각유로를 지나는 냉각수가 PCB 기판(120) 및 커패시터(130)로 침투하는 것을 방지할 수 있게 된다. When a cooling passage for cooling the driving motor is disposed in the space below the partition plate 111a, the cooling water passing through the cooling passage penetrates into the PCB substrate 120 and the capacitor 130 .

전술한 바와 같이, 전기자동차용 OBC 모듈(100)은 발열기기인 커패시터(130)가 OBC 하우징(110)과 맞닿게 형성됨에 따라, 전도에 의해 커패시터(130)에서 발생하는 열원을 외부로 방출할 수 있게 된다. As described above, in the OBC module 100 for an electric vehicle, the capacitor 130, which is a heating device, is formed to abut the OBC housing 110, so that the heat source generated in the capacitor 130 is discharged to the outside .

또한, 커패시터(130)와 맞닿는 OBC 하우징(110)의 덮개부(112)에 방열핀(112a)을 형성함에 따라, 커패시터(130)에서 발생하는 열원을 보다 빠르게 방출할 수 있게 되어 커패시터(130)의 수명을 증대시킬 수 있게 된다. In addition, since the heat radiating fin 112a is formed on the lid portion 112 of the OBC housing 110 contacting the capacitor 130, the heat source generated in the capacitor 130 can be discharged more quickly, And the lifetime can be increased.

아울러, 커패시터(130)와 OBC 하우징(110) 사이에 열 전도성 소재의 방열패드(140)를 장착함에 따라, 커패시터(130)에서 발생하는 열원을 보다 빠르게 방출할 수 있게 되어 커패시터(130)의 수명을 증대시킬 수 있게 된다. In addition, since the heat radiation pad 140 of a thermally conductive material is mounted between the capacitor 130 and the OBC housing 110, the heat source generated by the capacitor 130 can be discharged more quickly, so that the life of the capacitor 130 . ≪ / RTI >
