Outside of (2), the structure which installed the fan 5 is taken. However, when the fan 5 is installed outside of the cabinet 2 as described above, the fan is not waterproof well and foreign matters are attached, which shortens the life of the fan or easily causes a failure, so that the heat radiation efficiency of the repeater is lowered. There was a problem that the controller of the repeater is easily damaged, and the maintenance cost such as cleaning or replacing the fan is high.

The present invention has been proposed in view of the problem of the heat dissipation of the communication device cabinet that generates a lot of heat, such as the conventional mobile communication repeater as described above, the present invention improves the heat dissipation efficiency, the fan is not exposed to the outside air, It is an object of the present invention to provide a heat dissipation device for a communication device cabinet having a new structure that can be prevented from being easily damaged due to foreign matter being attached or exposed to rainwater.

According to the present invention, a cabinet 11 having a built-in communication controller 12 for generating heat and a heat sink 14 disposed to form a circumferential wall of the cabinet 11 and having a plurality of heat sink fins 15 formed thereon are included. In the communication device, one side of the controller 12 in the cabinet 11 is installed to contact the inner wall of the heat sink 14, the air inlet 25 and the air outlet 26 into the cabinet 11 A heat exchange cylinder 20 having an air passage 21 formed therein, a fan 22 and 23 formed on the air passage 21 of the heat exchange cylinder 20, and the heat exchange cylinder 20 disposed adjacent thereto. A heat dissipation structure for a communication device cabinet is provided between the heat sinks 14 and configured as a heat transfer plate 30 having a plurality of thermoelectric elements 32 therein.

According to another feature of the invention, a heat dissipation device for a communication device cabinet is provided between the controller 12 and the heat exchange cylinder 20, wherein a heat pipe 34 having a heat medium is connected thereto.

According to the present invention, there is provided a heat exchanger cylinder 20 having fans 22 and 23 and an air passage 21 formed inside a cabinet 11 for a communication device, and the heat exchanger cylinder 20 and the rear surface of the cabinet 11 are provided. By providing a heat transfer plate 30 having a plurality of thermoelectric elements 32 therebetween, it is possible to quickly discharge the heated air in the cabinet 11 to the outside, while improving the heat dissipation effect while the fans 22, 23 ) Is located inside the cabinet 11, it is possible to increase the durability of the device by preventing the penetration of rainwater or foreign matter.

In addition, the heat generating source is connected between the heat generating cylinder 20 and the heat-generating heat pipe 24 between the controller 12 and the heat-exchanging cylinder 20 to quickly transfer heat generated from the controller 12 to the heat-exchanging cylinder 20 and release it. As a result, a communication device excellent in heat dissipation effect can be achieved.

Hereinafter, with reference to the drawings will be described a preferred embodiment of the present invention. FIG. 2 is a state diagram in which a cover of a communication device cabinet of an embodiment of the present invention is opened, FIG. 3 is a cross-sectional view taken along the line A-A of FIG. 2, and FIG. As shown, according to the present invention, there is provided a cabinet 11 in which a controller 12 for a communication device, such as a mobile communication repeater, is provided, and a plurality of heat dissipation fins 15 are provided on the rear or circumferential wall of the cabinet 11. It is composed of a protruding heat sink 14. The inside of the cabinet 11 is provided with a heat exchanger cylinder 20 installed on one side of the controller 12 to be in close contact with the inner wall of the heat sink 14. The heat exchange cylinder 20 is composed of a cylindrical body having a rectangular cross section, and both ends thereof have an air inlet 25 and an air outlet 26, and each of the air inlet 25 and the air outlet 26 has a fan ( 22 and 23 are attached. Accordingly, the air heated by the controller 12 inside the cabinet 11 is introduced into the air inlet 25 of the heat exchange cylinder 20 by the fans 22 and 23, and passes through the air passage 21 inside the air outlet 21. Exit 26 and flow back into the cabinet 11.

On the other hand, the heat transfer plate 30 according to the present invention is disposed between the heat exchange cylinder 20 and the rear heat sink 14 of the cabinet 11. A plurality of thermoelectric elements 32 are provided in the heat transfer plate 30, and when power is applied to the thermoelectric elements 32 by a power supply means not shown, the heat exchange cylinder 20 inside the cabinet 11 is provided. The inner surface of the heat transfer plate 30 facing the surface is cooled to cool the temperature of the air flowing through the heat exchange cylinder 20, and the outer surface of the heat transfer plate 30 exposed to the outside of the cabinet 11 is heated to release heat. do. Thus, the heat exchange cylinder 20 in the cabinet 11 performs a heat exchange action. The heat dissipation action of the heat exchanger cylinder 20 increases the heat dissipation efficiency in addition to the heat dissipation action of the existing heat sink 14.

In addition, according to the present invention, a plurality of heat pipes 34 are provided to connect between the heat generating cylinder 20 and the controller 12 which is a heat generating source. A heat medium is accommodated in the heat pipe 34 to quickly transfer heat generated by the controller 12, which is a heat generating source, to the heat exchange cylinder 20 through a heat medium in the heat pipe 24, thereby providing a heat exchange cylinder 20. ) Allows for rapid heat exchange with the outside. Thus, the heat generated by the controller 12 is more effectively removed.
