도 1 내지 도 3에 도시한 바와 같이 본 발명의 냉각파이프가 설치된 LCD 서셉터(10)는 일정 두께를 갖는 서셉터 몸체(11)와, 상기 서셉터 몸체(11)내에 외부 공급장치(도시 생략)로부터 냉기를 공급하는 공급부(21)와, 공급부(21)의 최초 시작점으로부터 공급된 냉기가 서셉터 내부를 순환한 후 배출되는 배출부(22)로 구성되어 서셉터 몸체(11) 전체에 걸쳐 내장 설치된 냉각파이프(20)와, LCD를 일정온도로 유지시키도록 서셉터 몸체(11)를 가열하는 히터(30)로 구성된다. As shown in FIGS. 1 to 3, the LCD susceptor 10 having the cooling pipe of the present invention includes a susceptor body 11 having a predetermined thickness and an external supply device (not shown) in the susceptor body 11. The supply unit 21 for supplying the cold air from the (), and the discharge unit 22 is discharged after the cold air supplied from the initial starting point of the supply unit 21 circulates inside the susceptor to cover the entire susceptor body (11) Built-in cooling pipe 20 and a heater 30 for heating the susceptor body 11 to maintain the LCD at a constant temperature.

상기 히터(30)는 서셉터 몸체(11)의 최하단부에 제1커버(31)에 의해 냉각파이프(20)와 접촉하지 않도록 구성하고, 냉각파이프(20)는 상기 히터(30)를 커버하 는 제1커버(31)의 상부에 구성하되, 히터(30)와 동일 라인에 위치하도록 배치한다.The heater 30 is configured not to contact the cooling pipe 20 by the first cover 31 at the lowermost end of the susceptor body 11, the cooling pipe 20 covers the heater 30 It is configured on the first cover 31, but disposed so as to be located on the same line as the heater (30).

상기 냉각파이프(20)는 제2커버(32)에 의해 커버되도록 구성하고, 제2커버(32)의 상부에는 제3커버(33)를 구성하여 냉각파이프(20)를 흐르는 냉기 온도의 급속 상승을 방지토록 한다. The cooling pipe 20 is configured to be covered by the second cover 32, and the third cover 33 is formed on the upper portion of the second cover 32 to rapidly increase the cold air temperature flowing through the cooling pipe 20 To prevent it.

상기 냉각파이프(20)는 도 4에 도시한 바와 같이 그 외부형상 및 유로가 원형, 사각형 등 특정형상에 제한되지 않으며, 공급부(21)와 배출부(22)가 파이프 형태로 분리 구성된다. 도 4에서는 사각형 형상인 냉각파이프(20)를 예로 들었다. As shown in FIG. 4, the cooling pipe 20 is not limited to a specific shape such as a circular shape and a rectangular shape, and the supply part 21 and the discharge part 22 are separated in a pipe shape. In FIG. 4, a cooling pipe 20 having a rectangular shape is taken as an example.

상기 냉각파이프(20)의 재질로는 서셉터(10)의 몸체(11)에 내장되고 그 하측에 히터(30)가 구성되는 것을 고려하여 열전도 및 내식성이 우수하고 열에 잘 견디며 자성이 없는 구리(Cu) 또는 스테인레스강(Sus)을 사용한다.In consideration of the material of the cooling pipe 20 is embedded in the body 11 of the susceptor 10 and the heater 30 is formed on the lower side of the cooling pipe 20 is excellent in thermal conductivity and corrosion resistance, heat-resistant, magnetic-free copper ( Cu) or stainless steel (Sus) is used.

이와 같이 구성된 본 발명의 냉각파이프20)가 설치된 LCD 서셉터(10)는 히터(30)에 의해 일정온도로 가열되어 LCD를 일정온도로 유지시키는 상태에서 고장이 발생되었거나 공정 완료 후 장비의 유지보수가 필요할 경우 외부공급장치로부터 냉기, 인체에 무해한 가스, He, PCW(Process Cooling Water) 및 갈덴(Galden) 등의 서셉터 냉각물질을 공급부(21)를 통해 공급받는다.The LCD susceptor 10 provided with the cooling pipe 20 of the present invention configured as described above is heated to a constant temperature by the heater 30 and maintains the LCD at a constant temperature. If necessary, the air is supplied to the susceptor cooling material such as cold air, gas harmless to the human body, He, PCW (Process Cooling Water) and galden (Galden) from the supply unit 21.

따라서 외부공급장치로부터 공급부(21)를 통해 공급된 냉기는 냉각파이프(20)를 통해 서셉터(10) 전체를 순환하면서 서셉터(10)의 온도를 저하시키며, 이후 배출부(22)를 통해 외부로 배출된다.Therefore, the cold air supplied through the supply unit 21 from the external supply device lowers the temperature of the susceptor 10 while circulating the entire susceptor 10 through the cooling pipe 20, and then through the discharge unit 22. It is discharged to the outside.

이때, 냉각파이프(20)를 흐르는 냉기는 제1커버(31)에 의한 히터(30)로부터 의 발열 차단에 의해 급속한 온도상승이 방지됨과 동시에 냉각파이프(20)를 커버하는 제2커버(32) 및 제3커버(33)에 의한 외부공기와의 접촉 차단에 의해 급속한 온도상승이 방지되어 서셉터(10)의 온도를 신속하게 저하시킨다. At this time, the cold air flowing through the cooling pipe 20 is prevented from the rapid rise in temperature by blocking the heat generated from the heater 30 by the first cover 31 and at the same time the second cover 32 to cover the cooling pipe 20 The rapid temperature rise is prevented by blocking the contact with the external air by the third cover 33, thereby rapidly decreasing the temperature of the susceptor 10.

냉각파이프(20)를 흐르는 냉기에 의해 서셉터(10)의 온도가 일정온도 이하로 저하된 것으로 판단되면 장비 유지 보수를 행한다. If it is determined that the temperature of the susceptor 10 is lowered below a predetermined temperature by cold air flowing through the cooling pipe 20, equipment maintenance is performed.

상술한 바와 같이 본 발명에 의한 냉각파이프가 설치된 LCD 서셉터에 따르면 다음과 같은 여러 가지 뛰어난 효과가 있다.As described above, according to the LCD susceptor provided with the cooling pipe according to the present invention, there are various excellent effects as follows.

첫째, 현재 LCD 서셉터의 온도를 325℃에서 100℃로 낮추는데 소요되는 시간이 5세대 서셉터는 8시간, 6세대 서셉터는 12시간, 7세대 서셉터는 18시간 정도 소요되는데 반해 본 발명의 냉각파이프를 설치한 LCD 서셉터는 50%이상의 온도저하 시간을 절약할 수 있어 장비유지 보수가 용이하다.First, the time required for lowering the temperature of the LCD susceptor from 325 ° C. to 100 ° C. is 8 hours for the 5th generation susceptor, 12 hours for the 6th generation susceptor, and 18 hours for the 7th generation susceptor. LCD susceptor with cooling pipe saves more than 50% of time of temperature drop, making equipment maintenance easy.

둘째, 장비의 유지 보수가 용이해짐에 따라 원가절감 및 생산성 향상에 기여하며, LCD 패널의 크기가 대형화됨에 따라 더욱 큰 효과가 있다.Second, as maintenance of equipment becomes easier, it contributes to cost reduction and productivity improvement, and as the size of LCD panel becomes larger, there is a greater effect.
