플라즈마 디스플레이 패널의 방열구조 { structure for radiating heat of plasma display panel }Heat dissipation structure of plasma display panel {structure for radiating heat of plasma display panel}

본 발명은 플라즈마 디스플레이 패널의 방열구조에 관한 것으로, 특히 패널에서 발생되는 열을 외부로 발산시킬 수 있는 플라즈마 디스플레이 패널의 방열구조에 관한 것이다.The present invention relates to a heat dissipation structure of a plasma display panel, and more particularly, to a heat dissipation structure of a plasma display panel capable of dissipating heat generated from the panel to the outside.

일반적으로, 플라즈마 디스플레이 패널(PDP : Plasma display panel)은 상하판 유리로 구성된 2개의 유리대향면에 전극을 만들고 그 사이에 방전기체를 넣어서 기체의 방전현상을 이용하여 화상을 표시하는 발광형 소자이다. 최근에는 플라즈마 디스플레이 패널은 응답속도가 빠르고 점유공간을 줄이면서 대형화가 가능하여 모니터는 비롯하여 차세대형 텔레비젼으로 개발되고 있다. 이러한 플라즈마 디스플레이 패널은 플라즈마상태의 방전기체를 이용하는데, 방전기체를 플라즈마상태로 만드는데 많은 열이 발생하게 된다. 따라서, 플라즈마 디스플레이 패널은 대형으로 제작하기 위해서는 반드시 자체에서 생기는 열을 외부로 충분히 방열시키도록 설계되어야 한다.In general, a plasma display panel (PDP) is a light emitting device that displays an image using a discharge phenomenon of a gas by making electrodes on two glass facing surfaces composed of top and bottom glass, and inserting a discharge gas therebetween. . In recent years, plasma display panels have been developed as next-generation televisions as well as monitors because they can be large in size while reducing the response speed and occupying space. The plasma display panel uses a discharge gas in a plasma state, and a lot of heat is generated to make the discharge gas into a plasma state. Therefore, the plasma display panel must be designed to sufficiently dissipate heat generated from itself to the outside in order to manufacture a large size.

종래의 플라즈마 디스플레이 패널은 도 1에 도시된 바와 같이, 영상이 재현되는 패널(100)의 앞뒷쪽에 필터판(110)과 회로판(120)이 각각 배치되어 있는 한편, 상기 패널(100)의 뒤쪽면에는 다수의 열전도시트(102)가 소정간격을 두고 부착되어 있고, 이 열전도시트(102)에 상기 패널(100)을 지지하도록 방열판(104)이 부착설치되도록 되어 있다.In the conventional plasma display panel, as shown in FIG. 1, the filter plate 110 and the circuit board 120 are disposed on the front and back of the panel 100 on which the image is reproduced, while the rear of the panel 100 is located. A plurality of heat conductive sheets 102 are attached to the surface at predetermined intervals, and the heat sink 104 is attached to the heat conductive sheets 102 so as to support the panel 100.

이와 같은 종래 플라즈마 디스플레이 패널은 패널(100)에서 발생되는 열이 열전도시트(102)와 방열판(104)을 통해서 방열되는데, 본체내부에 구비된 열전도시트(102)와 방열판(104)만으로 패널(100)에서 발생되는 고온의 열을 원활하게 식히지 못하여 방열효율이 좋지 않은 문제점이 있었다. 또한 패널을 대형으로 제작하거나 벽걸이용 텔리비젼으로 제작될 경우, 별도의 방열장치를 설치해야 하므로 생산비용이 증가되는 문제점이 있었다.In the conventional plasma display panel, heat generated from the panel 100 is radiated through the heat conducting sheet 102 and the heat dissipation plate 104. The panel 100 may be formed only by the heat conducting sheet 102 and the heat dissipation plate 104 provided inside the main body. There was a problem that the heat dissipation efficiency is not good because it does not cool the high temperature heat generated in the). In addition, when the panel is manufactured in a large size or a TV for wall-mounted, there is a problem that the production cost is increased because a separate heat dissipation device must be installed.

이에 본 발명은 상술한 바와 같은 문제점을 감안하여 안출한 것으로, 별도의 방열장치를 설치하지 않더라도 패널 주변을 부분변경하여 방열효율을 높일 수 있는 플라즈마 디스플레이 패널의 방열구조를 제공하는데 그 목적이 있다.Accordingly, an object of the present invention is to provide a heat dissipation structure of a plasma display panel which can improve heat dissipation efficiency by partially changing the periphery of a panel even without installing a separate heat dissipation device.

상기한 목적을 달성하기 위하여 본 발명은, 패널의 뒤쪽면에 소정의 간격을 두고 다수의 열전도시트가 부착되고, 이 열전도시트에 방열판이 설치되며, 상기 패널의 앞쪽에 필터판의 선단둘레를 따라 전면커버판이 설치되는 한편, 상기 방열판과 전면커버판 사이에 적어도 1개이상의 히트파이프가 연결된 구조로 되어 있다.In order to achieve the above object, the present invention, a plurality of heat conductive sheet is attached to the rear surface of the panel at a predetermined interval, the heat sink is installed on the heat conductive sheet, along the leading edge of the filter plate in the front of the panel While the front cover plate is installed, at least one heat pipe is connected between the heat sink and the front cover plate.

이와 같은 본 발명에 따른 플라즈마 디스플레이 패널의 방열구조에 의하면, 패널에서 발생되는 열이 열전도시트와 방열판으로 전달되고, 방열판으로 전단된 열은 히트파이프로 통해 전면커버판으로 전달되어 외부로 발산함으로써 방열효율을 높일 수 있게 된다.According to the heat dissipation structure of the plasma display panel according to the present invention, the heat generated from the panel is transferred to the heat conduction sheet and the heat sink, and the heat sheared by the heat sink is transferred to the front cover plate through the heat pipe to radiate to the outside. It is possible to increase the thermal efficiency.
