충전기보드의 일면에 열전도테이프로 방열판을 설치하고, 충전기보드의 다른 면에는 표면 실장형(Surface mountaining type) 표면실장소자(35)들의 실장부위(36) 표면에서 상하로 관통하도록 형성한 다수의 제 1비아홀(31)과, 표면 실장부위(36) 사이의 인접 공간부위(37) 표면에도 상하로 관통하도록 형성한 다수의 제 2비아홀(32)을 형성한 블랙박스 보조전원용 충전기보드(30)를 포함하여 구성한다.A heat sink is provided on one side of the charger board with a heat conductive tape.

상기, 제 2비아홀(32)은 내벽에 열전도코팅층(34)을 형성한다.The second via hole 32 forms a thermally conductive coating layer 34 on the inner wall.

상기 방열판(20)은 충전기보드(30)의 충전회로(30a) 대응 공간과 접하도록 하는 방열하우징(10) 바닥면이나, 방열 가능한 방열핀의 추가결합구성으로 할 수 있다.The heat radiating plate 20 may be a bottom surface of the heat radiating housing 10 to be in contact with the space corresponding to the charging circuit 30a of the charger board 30 or may be a further combined structure of heat radiating fins.

도 4 내지 7에서 충전회로(30a)를 이루는 트랜지스터, FET, 아이씨칩, 콘덴서 같은 표면실장소자(35)가 실장되는 실장부위(36)에는 제 1비아홀(31)이 다수 상하로 관통되도록 하고, 실장부위(36)가 아닌 인접 공간부위(37)에도 제 2비아홀(32)이 다수 관통되도록 하며, 제 1비아홀(21)의 내벽에는 열전도코팅층(33)이, 제 2비아홀(32)의 내벽에도 역시 열전도코팅층(34)을 이루며, 실장부위(36)는 상기 열전도코팅층(33)과 동일 재질로 연결되도록 도 6과 같이 코팅하여 열전도 효율을 극대화시킨다. 바람직한 열전도코팅층은 구리층을 들 수 있고, 바람직한 코팅층은 수 내지 수십㎛ 두께를 예시할 수 있다.4 through 7, a plurality of first via holes 31 are vertically passed through a mounting region 36 where a surface mount device 35 such as a transistor, an FET, an IC chip, and a capacitor is mounted, A large number of second via holes 32 are formed in the adjacent space portion 37 other than the mounting region 36. A thermal conductive coating layer 33 is formed on the inner wall of the first via hole 21 and a thermal conductive coating layer 33 is formed on the inner wall of the second via hole 32, And the mounting area 36 is coated with the same material as the thermal conductive coating layer 33 as shown in FIG. 6 to maximize heat conduction efficiency. A preferable heat conduction coating layer may be a copper layer, and a preferable coating layer may be a thickness of several to several tens of micrometers.

이와 같이 구성한 본원발명은 도 1 및 도 2 와 같이 블랙박스(3) 구동용 전원을 자동차 운전중에는 차량의 발전 전압을 이용하고, 동시에 운전 중에는 충전단자를 통한 발전 전압이 충전기보드(30)를 통하여 바테리(12)의 전압을 충전시킨다. 운전을 마치고 정차시에는 충전기보드(30)를 통하여 바테리(12) 전원을 블랙박스 (3)로 인가한다. 1 and 2, the power source for driving the black box 3 is driven by the power generation voltage of the vehicle while the vehicle is in operation, and at the same time, the power generation voltage through the charging terminal is supplied through the charger board 30 Thereby charging the voltage of the battery 12. The power source of the battery 12 is applied to the black box 3 through the charger board 30 when the vehicle is stopped.

이와 같이 충전과 방전시 기동하는 충전기보드(30)는 충전회로(30a) 작동시 발생하는 표면실장소자(35)의 발열은 도 6 및 도 7에 보인 열전도패드(38)와 접하는 실장부위(36)에서 받아 제 1비아홀(31) 내벽의 열전도코팅층(33)으로 분산 전달되고, 이는 다시 열전도테이프(39)에서 합하여져 보다 냉각 효율이 높은 방열판(20)을 통하여 순식간에 분산되어 방열 효과를 높여준다. 동시에 방열판(20)은 방열핀 구조를 더하여져 냉각 효율을 극대화시킬 수도 있다.The charger board 30, which is activated during charging and discharging as described above, is configured such that the heat generated by the surface mounting element 35 generated during the operation of the charging circuit 30a is transferred to the mounting region 36 (see FIG. 6 and FIG. 7) And is dispersed and transferred to the thermal conductive coating layer 33 on the inner wall of the first via hole 31. The thermal conductive coating is then mixed again with the thermal conductive tape 39 to be dispersed instantly through the heat sink 20 having a higher cooling efficiency, give. At the same time, the heat dissipating plate 20 may be added with a heat dissipating fin structure to maximize the cooling efficiency.

또한 열전도패드(38)를 통한 발열은 도 7과 같이 제 1비아홀(31)로 에너지가 큰 열이 전달되고 동시에 인접한 제 2비아홀(32)에도 충전기보드(30)를 통하여 동시에 전달되고, 제 2비아홀(32) 내벽의 열전도코팅층(34)을 통하여 방열판(20)으로 추가로 분산되므로 냉각시간을 단축시킨다. 열전도 량과 전달 방향을 화살표 크기와 방향으로 예시하면 도 7과 같이 표기할 수 있다. 이는 제 2비아홀(32)측을 통한 방열은 상대적으로 작아서, 남은 방열 기능을 제 1비아홀(31) 측 열을 흡수하는 것을 의미하며, 이러한 추가 흡수 기능 때문에 방열효율을 향상시킨다.As shown in FIG. 7, the heat generated by the heat conductive pad 38 is transferred to the first via hole 31 through the charger board 30 and simultaneously transmitted to the adjacent second via hole 32, It is further dispersed into the heat sink 20 through the heat conductive coating layer 34 on the inner wall of the via hole 32, thereby shortening the cooling time. The amount of heat conduction and the direction of transmission can be represented by arrows in the size and direction as shown in FIG. This means that the heat dissipation through the second via hole 32 side is relatively small, so that the remaining heat dissipation function is absorbed by the first via hole 31 side, and the heat dissipation efficiency is improved due to this additional absorption function.

아울러 본원발명은 도 1 과 같이 충전기보드(30)에 설치된 방열판(20)은 동시에 방열 기능을 가지는 소재로 만든 블랙박스 보조전원장치를 이루는 방열하우징(10)의 내면에 접하도록 설치하므로, 방열하우징(10) 표면으로 전도되는 열을 방열시켜, 충전기보드(30)의 방열 열은 제 1 및 제 2비아홀(31,32), 방열판(20), 방열하우징(10)을 통하여 자연방열되므로, 안정적으로 발열로 인한 문제를 해결하는 방열효율이 좋은 블랙박스 보조전원장치를 제공한다.1, the heat sink 20 provided on the charger board 30 is installed to contact the inner surface of the heat sink housing 10 constituting a black box auxiliary power source device made of a material having a heat radiation function at the same time, Since the heat dissipated from the surface of the charger board 30 is radiated through the first and second via holes 31 and 32, the heat sink 20 and the heat dissipation housing 10, Which provides a black box auxiliary power supply having a good heat dissipation efficiency for solving the problem caused by heat generation.
