본 고안은 편향요크에 관한 것으로서, 보다 상세하게는 투사형 텔레비젼에 적합한 방열형 편향요크에 관한 것이다.The present invention relates to a deflection yoke, and more particularly, to a heat dissipation deflection yoke suitable for a projection television.

편향요크는 음극선관의 편넬 외주에 부착되어서 전자총으로 부터 방사되는 전자비임에 자계를 가하여 주는 것이므로 음극선관에 있어서 자체 발열이 심한 부품의 하나로 되고 있다.The deflection yoke is attached to the outer periphery of the cathode ray tube and applies a magnetic field to the electron beam radiated from the electron gun. Therefore, the deflection yoke is one of the components with high self-heating in the cathode ray tube.

편향요크가 자체발열에 의해 승온될 경우, 서어멀 드리프트를 일으켜 화질을 열화시키게 된다.When the deflection yoke is heated by self-heating, a thermal drift causes a deterioration in image quality.

종래에는 텔레비젼의 화면이 20인치 이내의 것이 범용화 되었으므로 페라이트코어의 순도를 높이는 정도만으로도 편향요크의 발열에 의한 서어멀 드리프트가 생기지 않게 할 수 있었으나, 최근의 화질 향상에 발 맞추어 대형화면을 요구하는 경향이 생김에 따라, 편향요크에도 서어멀 드리프트에 의한 문제점이 대두되기 시작하고 있다.Conventionally, since TV screens are generally used within 20 inches, thermal drift due to heat generation of the deflection yoke can be prevented by just raising the purity of the ferrite core. As a result of this, problems caused by thermal drift have started to arise in deflection yokes.

대형화면을 갖는 브라운관에는 고주파를 채용하고 있으며, 이 고주파는 수평코일의 경우 200KHZ이상 적용되고 있다.The high frequency is adopted in the CRT with the large screen, and the high frequency is applied over 200KHZ for the horizontal coil.

주지된 바와 같이 코일에 고주파를 흘리면 상당히 높은 온도로, 발열을 일으키게 된다.As is well known, high frequency flow in a coil causes heat to be quite high.

이 고주파에 의한 가열은 편향요크 자체의 자연 냉각으로 해결하기 곤란한 수준의 것이므로 강제 냉각을 위한 수단이 필요하게 된다.Since the heating by the high frequency is a level which is difficult to solve by the natural cooling of the deflection yoke itself, a means for forced cooling is required.

종래에는 전자회로에 개재되는 파워트랜지스터 등의 소자를 방열하기 위한 휀 모우터로 하우징의 내부를 환기시키는 방식으로 부분적인 강제 냉각이 이루어지게 하고 있으나 만족할 정도는 되지 못하고 있다.In the related art, partial forced cooling is performed by venting the inside of the housing with a fan motor for dissipating an element such as a power transistor interposed in an electronic circuit, but it is not satisfactory.

본 고안은 이와 같은 문제점을 해결하기 위하여, 편향요크에서 발열이 심한 부분의 열을 방산할 수 있게 구성한 방열형 편향요크를 제공함에 있다.The present invention is to provide a heat dissipation-type deflection yoke configured to dissipate heat in the heat generated in the deflection yoke in order to solve such a problem.

이에 따라 본 고안은 세퍼레이터의 외주에 부착되어 내측의 수직코일에서 방산되는 열을 받는 수열판과, 이 수열판으로 부터 전도된 열을 주위로 방산하는 방열휜과, 편향요크로 부터 발생하는 열의 방산경로를 한정하는 반사판으로 구성된 방열부재가 외부에 설치됨을 특징으로 한다.Accordingly, the present invention is attached to the outer periphery of the separator receives a heat dissipated from the inner vertical coil, a heat radiation plate for dissipating heat conducted from the heat sink to the surroundings, and heat dissipation from the deflection yoke Characterized in that the heat dissipation member consisting of a reflecting plate defining a path is installed on the outside.

이하, 본 고안의 바람직한 실시예를 첨부도면에 따라 상세히 설명한다.Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

제 1 도는 본 고안의 분해 사시도로서 방열부재(1)은 편향요크를 구성하는 세퍼레이터(2)의 외주면에 일치하는 형상으로 된 수열판(3)과, 이 수열판에서 연장되어 끝부분이 임의 형태로 다수 분지된 방열휜(4) 및 이 방열휜(4)의 외측에 형성되어 세퍼레이터(2)의 외측방을 차폐하는 반사판(5)로 구성되어 있다.1 is an exploded perspective view of the present invention, wherein the heat dissipation member 1 has a heat receiving plate 3 having a shape corresponding to the outer circumferential surface of the separator 2 constituting the deflection yoke, and extends from the heat receiving plate to form an end portion in an arbitrary shape. The heat dissipation fan 4 branched into many and the reflecting plate 5 formed in the outer side of this heat dissipation fan 4, and shielding the outer side of the separator 2 are comprised.

이렇게 구성된 방열부재(1)은 제 2 도에 도시한 바와 같이, 세퍼레이터(2)의 외주면에서 내측의 수평코일(6)이 설치된 자리에 맞추어 부착된 다음, 그위로 피착되는 수직코일 및 페라이트코어(7)에 의해 세퍼레이터(2)의 외주면 상에 부착된다.As shown in FIG. 2, the heat dissipation member 1 configured as described above is attached to a position where the inner horizontal coil 6 is installed on the outer circumferential surface of the separator 2, and then the vertical coil and the ferrite core are deposited thereon. 7) on the outer circumferential surface of the separator 2.

이렇게 부착된 방열부재(1)의 반사판(5)는 도시한 바와 같이 수직코일 및 페라이트코어(7)의 외주에 현수되어 대류통로로 형성하게 된다.The reflective plate 5 of the heat dissipation member 1 attached as described above is suspended on the outer circumference of the vertical coil and the ferrite core 7 to form a convection path as shown.

그 결과로, 본 고안의 편향요크를 갖춘 음극선관이 동작될 때, 수평코일(6)의 고주파에 의한 발열은 방열부재(1)의 수열판(3)에 흡수되어 방열휜(4)를 통해 방산되는 것이며, 이 과정에서 하우징에 배치된 휀모우터(도시생략)에 의해 대류는 도면의 화살표로 도시한 바와 같이 형성되어 하우징 외부로 도출되는 것이므로 다른 부품에 열이 전파되는 일이 없이 바람직하게 방열되어, 편향요크의 서어멀드리프트를 방지하여 주게 된다.As a result, when the cathode ray tube with the deflection yoke of the present invention is operated, heat generated by the high frequency of the horizontal coil 6 is absorbed by the heat receiving plate 3 of the heat dissipation member 1, In this process, convection is formed as shown by the arrow in the drawing and drawn out of the housing by the shock motor (not shown) disposed in the housing, so that heat is not transmitted to other parts. Heat dissipation prevents thermal drift of the deflection yoke.

또한, 다수의 방열휜(4)는 연결대(8)에 의해 상호 일정간격을 이루어 배열되는 것이고, 또 필요하다면 방열휜(4)에 통기공(9)을 무수히 뚫어 놓아 대류가 잘되게 할 수도 있다.In addition, the plurality of heat dissipation fins 4 are arranged at regular intervals by the connecting table 8, and if necessary, the ventilation holes 9 may be drilled innumerably through the heat dissipation fins 4 so as to allow convection to be good.

상술한 바와 같이 본 고안은 편향요크에서 발생하는 발열을 효과적으로 또한 일정경로를 통하여 방산시킬 수 있게 한 것이므로 다른 부품에 영향을 주지 않고 편향요크의 서어멀 드리프트를 근본적으로 해결할 수 있는 실용성을 갖는다.As described above, since the present invention enables dissipation of heat generated in the deflection yoke effectively and through a predetermined path, the present invention has the practicality of fundamentally solving the thermal drift of the deflection yoke without affecting other components.
