It's about structure.

본 발명은 전술한 바와 같은 종래의 이동통신 중계기와 같이 열이 많이 발생되는 통신기기 캐비넷의 방열상의 문제점에 착안하여 제안된 것으로서, 본 발명은 방열효율을 높이면서도, 팬이 외기에 노출되지 않아서, 이물질이 부착되거나 빗물 등에 노출되어 쉽게 손상되는 것을 방지하여 내구성을 향상시킬 수 있는 새로운 구조의 통신기기 캐비넷용 방열장치를 제공하고자 하는 것이다.The present invention has been proposed in view of the problem of heat dissipation of a communication device cabinet that generates a lot of heat like the conventional mobile communication repeater as described above. An object of the present invention is to provide a heat dissipation device for a communication device cabinet of a new structure that can improve durability by preventing foreign substances from being attached or being easily damaged by exposure to rainwater.

본 발명에 따르면, 열을 발생하는 통신용 컨트롤러가 내장된 캐비넷과, 이 캐비넷의 둘레벽을 이루도록 배치되며 다수의 방열핀이 형성된 히트싱크를 포함하는 통신기기에 있어서, 캐비넷 내부의 상기 컨트롤러의 일측에는 히트싱크의 내벽에 접촉되도록 설치되며 캐비넷 내부로 공기유입구와 공기유출구가 개방되도록 공기통로가 형성된 열교환통체와, 상기 열교환통체의 공기통로상에 형성된 팬과, 상기 열교환통체와 이에 인접배치되는 히트싱크 사이에 개재되며 내부에 다수의 열전소자가 구비된 열전달판으로 구성된 것을 특징으로 하는 통신기기 캐비넷용 방열구조가 제공된다. 본 발명의 다른 특징에 따르면, 상기 컨트롤러와 열교환통체 사이에는 열매체가 내장된 히트파이프가 접속된 것을 특징으로 하는 통신기기 캐비넷용 방열장치가 제공된다.According to the present invention, in a communication device comprising a cabinet in which a communication controller for generating heat is built in, and a heat sink disposed to form a peripheral wall of the cabinet and having a plurality of heat dissipation fins formed therein, a heat sink is provided on one side of the controller inside the cabinet Between the heat exchange cylinder installed so as to be in contact with the inner wall of the sink and having an air passage so that an air inlet and an air outlet are opened into the cabinet, a fan formed on the air passage of the heat exchange tube, and the heat exchange tube and a heat sink disposed adjacent thereto There is provided a heat dissipation structure for a communication device cabinet, which is interposed in and consists of a heat transfer plate having a plurality of thermoelectric elements therein. According to another feature of the present invention, there is provided a heat dissipation device for a communication device cabinet, characterized in that a heat pipe having a built-in heating medium is connected between the controller and the heat exchange cylinder.

본 발명에 따르면, 통신기기용 캐비넷의 내부에 팬와 공기통로가 형성된 열교환통체를 구비하고, 이 열교환통체와 캐비넷 배면 사이에는 다수의 열전소자를 구비한 열전달판을 구비함으로써, 캐비넷 내부의 가열된 공기를 신속하게 외부로 배출할 수 있어서, 방열효과를 높이면서도 팬이 캐비넷의 내부에 위치되므로, 빗물이나 이물질의 침투를 방지하여 장치의 내구성을 높일 수 있다. 또한, 열발생원인 컨트롤러와 열교환통체 사이에는 열매체가 내자오된 히트파이프를 연결하여 컨트롤러에서 발생된 열을 신속하게 열교환통체로 전달하여 방출할 수 있으므로, 더욱 열방출효과가 우수한 통신기기를 달성할 수 있다.According to the present invention, a heat exchange cylinder having a fan and an air passage formed therein is provided in a cabinet for communication devices, and a heat transfer plate having a plurality of thermoelectric elements is provided between the heat exchange cylinder and the rear surface of the cabinet, whereby heated air inside the cabinet is provided. Since the fan is located inside the cabinet while increasing the heat dissipation effect, the durability of the device can be increased by preventing the penetration of rainwater or foreign substances. In addition, since the heat generated by the controller can be quickly transferred to the heat exchange tube and discharged by connecting a heat pipe with a heat medium resistance between the controller and the heat exchange tube, which is the source of heat, it is possible to achieve a communication device with an excellent heat dissipation effect. can

이하에서 내용을 참조하여 본 발명의 바람직한 실시예를 설명한다. 본 발명에 따르면, 이동통신 중계기와 같은 통신기기용 컨트롤러가 내장된 캐비넷이 구비되는데, 이 캐비넷의 배면이나 둘레벽에는 다수의 방열핀이 돌출형성된 히트싱크로 구성된다. 그리고, 캐비넷의 내부에는 상기 컨트롤러의 일측에 히트싱크의 내벽에 밀착되도록 설치된 열교환통체가 구비된다. 이 열교환통체는 단면사각형의 통체로 구성된 것으로서, 그 양단은 공기유입구와 공기유출구가 형성되고, 이 공기유입구와 공기유출구의 각각에는 팬이 부착된다. 따라서 캐비넷 내부의 컨트롤러에 의해 가열된 공기가 팬에 의해 열교환통체의 공기유입구로 유입되어 내부의 공기통로를 지나서 공기유출구로 나와서 다시 캐비넷 내로 흐르게 된다. 한편, 이 열교환통체와 캐비넷의 배면 히트싱크 사이에는 본 발명에 따른 열전달판이 배치된다. 이 열전달판의 내부에는 다수의 열전소자가 구비되어, 도시안된 전원공급수단에 의해 이 열전소자에 전원이 인가되면, 캐비넷 내부의 열교환통체에 면한 열전달판의 내측면은 냉각되어이 열교환통체로 흐르는 공기의 온도를 냉각시키고, 캐비넷 외부로 노출되는 열전달판의 외측면은 가열되어 열을 방출한다. 이로써, 캐비넷 내의 열교환통체가 열교환작용을 수행하게 된다. 이러한 열교환통체의 방열작용은 기존에 구비된 히트싱크의 방열작용에 더하여 방열효율을 증대시킨다. 또한, 본 발명에 따르면, 열발생원인 컨트롤러와 열교환통체 사이를 연결하는 다수의 히트파이프가 구비된다. 이 히트파이프의 내부에는 열매체가 수용되어 열발생원인 컨트롤러에서 발생된 열을 신속하게 히트파이프내부의 열매체를 통해 열교환통체로 전달함으로써, 열교환통체에서 외부와 신속하게 열교환이 이루어지도록 한다. 따라서 컨트롤러에서 발생된 열이 더욱 효과적으로 제거된다.Hereinafter, preferred embodiments of the present invention will be described with reference to the contents. According to the present invention, there is provided a cabinet with a built-in controller for communication devices such as a mobile communication repeater, and a heat sink having a plurality of heat dissipation fins protruding from the rear or peripheral wall of the cabinet is provided. And, inside the cabinet, a heat exchange cylinder is provided on one side of the controller so as to be in close contact with the inner wall of the heat sink. This heat exchange cylinder is composed of a cylinder having a rectangular cross-section, and an air inlet and an air outlet are formed at both ends thereof, and a fan is attached to each of the air inlet and the air outlet. Therefore, the air heated by the controller inside the cabinet is introduced into the air inlet of the heat exchange cylinder by the fan, passes through the internal air passage, comes out through the air outlet, and flows back into the cabinet. On the other hand, a heat transfer plate according to the present invention is disposed between the heat exchange cylinder and the rear heat sink of the cabinet. A plurality of thermoelectric elements are provided inside the heat transfer plate, and when power is applied to the thermoelectric element by a power supply means (not shown), the inner surface of the heat transfer plate facing the heat exchange tube inside the cabinet is cooled and air flowing into the heat exchange tube to cool the temperature, and the outer surface of the heat transfer plate exposed to the outside of the cabinet is heated to release heat. Accordingly, the heat exchange cylinder in the cabinet performs a heat exchange action. The heat dissipation action of the heat exchange cylinder increases the heat dissipation efficiency in addition to the heat dissipation action of the conventionally provided heat sink. In addition, according to the present invention, a plurality of heat pipes connecting between the heat generating source and the heat exchange cylinder are provided. The heat medium is accommodated inside the heat pipe, and heat generated from the controller, which is a heat generating source, is quickly transferred to the heat exchange cylinder through the heat medium inside the heat pipe, so that the heat exchange cylinder can quickly exchange heat with the outside. Therefore, the heat generated by the controller is more effectively removed.
