본 고안은 고휘도가 요구되는 투사형 음극선관의 액냉장치에 관한 것으로서, 특히 냉매와 접하는 내측면에 흡열휜(fin)을 형성하여 냉각효율을 향상시키게 한 음극선관의 액냉장치에 관한 것이다.The present invention relates to a liquid cooling device of a projection type cathode ray tube requiring high brightness, and more particularly, to a liquid cooling device of a cathode ray tube which improves cooling efficiency by forming an endothermic fin on an inner surface in contact with a refrigerant.
투사형 음극선관은 R.G.B 색상중의 하나에 해당되는 모노칼라 음극선관 3개로 부터 현출되는 화상을 스크린상에서 중합시켜 대형의 칼라화상으로 되게한 것으로서, 영상확대에 의한 휘도 저하를 고려하여 고휘도를 갖추게 설계된다.Projection type cathode ray tube is a large color image by polymerizing image appearing from three mono color cathode ray tube corresponding to one of RGB colors on screen and designed to have high brightness in consideration of deterioration of brightness caused by image magnification. .
음극선관의 휘도 증대는 애노오드에 인가하는 전압을 높이는 방법으로 하고 있으며, 예컨대 투사형 음극선관에는 30KV이 고전압이 애노오드에 인가된다.The brightness of the cathode ray tube is increased by increasing the voltage applied to the anode. For example, a high voltage of 30 KV is applied to the anode in the projection cathode ray tube.
그러나 애노오드에 고전압이 인가되면 화상이 현출되는 패널의 온도가 매우 높게 승온되어 화질이 열화되는 문제를 일으키게 되믈로 반드시 별도의 액냉장치가 음극선관의 패관의 부설된다.However, when a high voltage is applied to the anode, the temperature of the panel where the image is displayed is raised to a very high temperature, which causes a problem of deterioration in image quality. Therefore, a separate liquid cooling device is necessarily installed in the shell of the cathode ray tube.
투사형 음극선관에서 공지된 액냉장치는 제3도에 도시한 바와 같이 패널의 외주를 둘러 쌓는 프레임(1)의 외주면에 다수의 방열휜(2)을 돌출 형성하고, 상기 프레임 (1)의 일측 개구에 투명판(3)을 기밀하게 부착시킨 구성으로 되어 있다.The liquid-cooling apparatus known in the projection type cathode ray tube projects a plurality of heat radiation fins 2 on the outer circumferential surface of the frame 1 surrounding the outer circumference of the panel as shown in FIG. The transparent plate 3 is attached to the airtight structure.
프레임(1)은 패널과 접하는 면에 간격유지용 돌기(4)를 보유하는 한편, 외주일측에는 캐비넷에 연결되는 블래킷(5)을 형성하고 있다.The frame 1 has a space keeping projection 4 on a surface in contact with the panel, and on the outer circumferential side, a frame 5 is connected to the cabinet.
상기 방열휜(2)은 투명판(3)과 패널 사이로 형성되는 공간에 충전된 냉매의 열을 프레임(1)을 통해 자연 전도받아 외부로 방산시켜 냉각되게 하는 역활을 한다.The heat dissipation fan (2) serves to allow the heat of the refrigerant charged in the space formed between the transparent plate (3) and the panel to be naturally conducted through the frame (1) to dissipate to the outside to cool.
그러나 이와 같은 구조의 액냉장치가 방열효율은 방열휜의 면적에 의해 정해지게 되므로 일정한 한계가 생기게 마련이다.However, the liquid-cooling device of such a structure has a certain limit because the heat radiation efficiency is determined by the area of the heat radiation fan.
본 고안의 목적은 상기와 같은 종래의 액냉장치에서 볼수 있는 흡열효과의 한계를 극복하기 위하여 냉매와의 접촉면적을 최대로 증대시킬 수 있는 투사형 음극선관의액냉장치를 제공함에 있다.An object of the present invention is to provide a liquid cooling device of a projection type cathode ray tube that can maximize the contact area with the refrigerant in order to overcome the limitation of the endothermic effect seen in the conventional liquid cooling device as described above.
상기 목적에 따라 본 고안은 외주면에 다수의 방열휜이 배열되어 있는 통상의 액냉장치에 있어서 그 내측면에 다수의 흡열휜을 돌출 형성하여 구성됨을 특징으로 한다.According to the above object, the present invention is characterized in that it is configured by protruding a plurality of heat absorbing fins on the inner surface in a conventional liquid cooling device in which a plurality of heat radiation fins are arranged on the outer peripheral surface.
상기 흡열휜은 냉매의 대류방향에 맞추어 연장된다.The endothermic wall extends in accordance with the convective direction of the refrigerant.
이하 본 고안은 첨부도면에 따라 상세히 설명한다.Hereinafter, the present invention will be described in detail according to the accompanying drawings.
이 실시예에서 상기 제3도와 동일한 부분은 설명의 중복을 피하고자 동일부호를 부여하기로 한다.In this embodiment, the same parts as those in FIG. 3 will be given the same reference numerals to avoid duplication of explanation.
제1도를 참조하면 외주면에 다수의 방열휜(2)이 돌출 형성된 프래임(1)은 내주면의 길이방향에도 대략 유사한 형상의 흡열휜(6)을 상기 방열휜(2)에 평행하게 다수 형성하고 있다.Referring to FIG. 1, a frame 1 having a plurality of heat dissipation fins 2 protruding from its outer circumferential surface has a plurality of heat absorbing fins 6 having a substantially similar shape in the longitudinal direction of the inner circumferential surface in parallel to the heat dissipating fins 2. have.
이러한 구성의 프레임(1)은 제2도의 도시와 같이 음극선관의 패널(P) 전면에 정착되어 주변이 시일재(7)로 밀봉처리됨에 따라 상기 패널(P)과 투명판(3)사이로 냉매수용부(8)가 형성된다.The frame 1 of this configuration is fixed to the front surface of the panel P of the cathode ray tube as shown in FIG. 2 and the surroundings are sealed with the sealing material 7 so that the refrigerant is between the panel P and the transparent plate 3. The receiving portion 8 is formed.
음극선관이 동작되어 패널(P)의 표면온도가 상승되면 그 표면에 접촉된 냉매는 보다 낮은 온도로 분포되는 투명판(3)쪽으로 도면의 화살표로 나타낸 바와 같이 대류하게 된다.When the cathode ray tube is operated to increase the surface temperature of the panel P, the refrigerant in contact with the surface is convexed toward the transparent plate 3 distributed at a lower temperature as indicated by the arrow in the figure.
이와 같이 냉매의 대류중에 주변부에서는 다수 배열된 흡열휜(6)과 접촉하여 이 부분을 통해 열전도가 이루어지게 된다.In this way, during the convection of the refrigerant, a plurality of heat-absorbing end (6) arranged in the peripheral portion is in contact with the heat conduction through this portion.
현편, 흡열휜(6)은 프레임(1)과 일체로 형성된것이므로 전도된 열은 프레임(1)의 외주에 형성된 방열휜(2)을 통해 외부로 방산된다.Since the string and endothermic heat 6 is formed integrally with the frame 1, the conducted heat is dissipated to the outside through the heat radiation heat 2 formed on the outer circumference of the frame 1.
이상과 같은 본 고안은 투사형 음극선관의냉매를 냉각시킴에 있어서, 프레임과 냉매 사이의 접촉면적을 흡열휜으로 대폭 확장시킴에 따라 냉매와 프레임 사이의 열전도효율을 향상시켜서 투사관의 냉각효율을 저하에 의한 문제점을 근본적으로 개선시킨 실용성을 갖고 있다.In the present invention as described above, in cooling the refrigerant of the projection type cathode ray tube, by greatly expanding the contact area between the frame and the refrigerant by endothermic heat, the thermal conductivity between the refrigerant and the frame is improved, thereby lowering the cooling efficiency of the projection tube. It has the practicality which fundamentally improved the problem by the.
