STRUCTURE FOR CABINET HOUSING OF A WIRELESS COMMUNICATION SYSTEM}

The present invention relates to an enclosure structure of a wireless communication system, and more particularly, to an enclosure structure of a wireless communication system that can make maximum use of an internal space and facilitates mounting and replacement of a module.

In the present invention, the wireless communication system includes both one-way and two-way wireless communication systems such as paging, cellular and PCS mobile communication, wireless communication such as WLL, and next generation mobile communication system including IMT-2000.

In general, the repeaters used in the wireless communication system are classified into various types according to the connection state with the base station, and have various enclosure structures to operate so as to maintain reliability in the outdoor environment according to the output power (power consumption). Its internal structure also takes many forms.

In the conventional method, passive cooling using heat sinks is used for small output devices (usually around 200 Watts), and heat exchangers are used for medium and large output devices (usually more than 300 Watts). Is using.

For dual small output equipment, a heating element (e.g. high power amplifier-high power amplifier (HPA) or linear amplifier-linear power amplifier (LPA), power supply) is attached to the heat sink, and other components are attached to the periphery Since it is arranged in the form, it is difficult to implement a compact housing structure that is easy to assemble and disassemble.

In addition, in the case of high power consumption, this approach does not guarantee the reliability of the equipment under outdoor operating conditions. Therefore, in order to solve the problem of heat treatment of high-power equipment, when an active cooling enclosure is formed by using a heat sink, a heat exchanger, or an air conditioner with a fan, outdoor operating conditions may be satisfied.

Its assembly and disassembly is very difficult, and some of the internal spaces cannot be used, which reduces the efficiency of using the internal space of the enclosure.

The rack structure shown in FIG. 1 is configured to mount a plurality of modules in a rack inside the enclosure. This method has the advantage of a neat finish and strong feeling, and the easy replacement and mounting of the module is easy to replace the module, but the module is remounted in the actual enclosure, so the overall cable connection The process takes a lot of work and the structure becomes complicated.

In addition, in order to wire the RF signal, a door must be installed at the rear, and the size of the entire enclosure is large, such that it is difficult to implement a compact enclosure.

The present invention is to solve the conventional problems as described above, the object of the present invention is to provide a housing structure of a wireless communication system that can prevent noise by using a passive cooling method, and can improve the cooling efficiency.

In order to achieve the above object, the present invention provides a main body having a storage space therein, a door installed on one surface of the main body, a heat sink forming at least one surface of the main body, and an inner surface of the heat sink. Wireless communication including a heating element, a plurality of heat dissipation fins installed in the upper portion of the body and connected through the heat generating element and the heat pipe, and an inclined protrusion coupling portion formed on the heat dissipation fin and coupled to the heat pipe at an inclined angle. It is characterized by the enclosure structure of the system.
