The present invention relates to a mesh base station rack door for shielding electromagnetic waves, and more particularly, to a rack door having a mesh structure using honeycomb or a mesh & modular panel capable of smoothing heat circulation and shielding electromagnetic waves. By designing and manufacturing, it relates to an electromagnetic shielding network base station rack door to prevent in advance the malfunction and fatal damage between the communication devices due to the leakage of electromagnetic waves, and human body concerns.

As is well known, communication equipment is very sensitive to temperature, so when the operating temperature is high, the output value changes and the product deteriorates rapidly, affecting the life of the equipment.

For this reason, as a result of operating the communication device by removing the door as shown in FIG. 1B, when the air flow is smooth, the temperature drop effect is tested at the minimum 5 ° C operating temperature drop effect compared to the operation with the door. It was confirmed through. At this time, the temperature difference for each measuring point in the state that the door of the base station equipment is separated as shown in Table 1 below.

Measuring point location Temperature difference (℃) ① External temperature (Chamber temperature) 1.4 ② System middle 5.4 ④ MPAU front (alpha) 3.3 ⑤ MPAU side (gamma) 3.1 ⑦ MPAU side (beta) 2.1 ⑧ System top 4.3 ⑨ DTRA B'd side 2.6 ⑩ Fan bottom entrance 2.5

However, since the conventional base station equipment rack door is designed as a simple opening and closing structure as shown in Figure 1a, when the door is closed and operated, hot air generated inside is not easily discharged to the outside, and the door can be separated and operated as shown in Figure 1b. In this case, there is a problem that the electromagnetic wave is leaked out exceeding the standards of the Radio Wave Research Institute Notice No. 006-126.

That is, when the base station equipment rack door is opened as shown in FIG. 1B, it was measured through experiments that electromagnetic waves exceeding the specification were leaked in the frequency band of 200 MHz or more as shown in Tables 2 and 3 below. At this time, Table 2 below shows vertical polarization measurement, and Table 3 shows horizontal polarization measurement.

[When measuring vertical polarization] Frequency (Mhz) Electromagnetic wave standard Close (Level) Open (Level) 30.3 40 35.3 37.5 196.6 40 38.5 48.4 858 47 31.1 45.7

[When measuring horizontal polarization] Frequency (Mhz) Electromagnetic wave standard Close (Level) Open (Level) 196.6 40 31.2 44.6 858 47 29.3 45.7 990 47 31.7 45.4

Therefore, the base station equipment attached to the conventional base station equipment rack door, as described above, when the door is opened or operated or closed and operated, the equipment deterioration or electromagnetic damage occurs according to each, inconvenience caused by equipment operation and maintenance There was a problem that the increase in cost and cost.

Accordingly, the present invention has been made to solve the conventional problems as described above, an object of the present invention by designing and manufacturing a rack door of the mesh structure using a honeycomb or mesh modular panel capable of heat circulation smoothly and electromagnetic shielding In addition, the present invention provides an electromagnetic shielding base station rack door to prevent a malfunction and fatal damage between communication devices caused by the leakage of electromagnetic waves, and a risk of harm to human beings in advance.

Another purpose is to prevent heat shortening due to deterioration of equipment by allowing thermal circulation inside the base station equipment to be performed smoothly, thereby reducing the maintenance cost of equipment management and replacement. To provide a network base station rack door.

In order to achieve the above object, the present invention electromagnetic shielding net structure base station rack door is installed in the front of the base station equipment rack in the base station rack door to protect the equipment from the outside,

Forming a frame of the same rectangular shape as the shape of the front of the base station equipment rack, characterized in that the structure is fixed by applying an adhesive to the internal space of the frame and inserting the honeycomb of the network structure.

In addition, the present invention electromagnetic shielding net structure base station rack door is installed in the front of the base station equipment rack in the base station rack door to protect the equipment from the outside,

Forming a frame having a rectangular shape identical to the shape of the front of the base station equipment rack, it is characterized in that the structure is fixed by applying an adhesive to the internal space of the frame and inserting a mesh modular panel of the network structure.

Hereinafter, with reference to the accompanying drawings for the electromagnetic shielding net structure base station rack door according to the present invention will be described in detail.

Figure 2 is a view showing the appearance of the electromagnetic shielding net structure base station rack door in accordance with an embodiment of the present invention, which is the same rectangular frame as the shape of the base station equipment rack (Lack) 1 ( 100 is formed, by applying an adhesive to the inner space of the frame 100 and inserting the honeycomb 200 of the network structure is formed. At this time, the frame 100 is manufactured using a steel material.

On the other hand, a pair of door hinges (Door Hinge) 110, as shown in Figure 2 is provided on one side upper and lower portions of the frame 100. Therefore, the present invention is installed in a hinged manner in the base station equipment rack 1, which is possible to open / close.

In addition, one side of the frame 100 is formed with a handle 120 capable of a door lock (Doorlock). In this case, the above-described method of implementing the door may be implemented in a sliding method or both open methods.

Therefore, according to the rack door using the honeycomb 200 as in the embodiment of the present invention described above, even when the base station equipment (1) close the rack door to operate so that both the temperature improvement effect and the electromagnetic shielding effect can be satisfied do.

On the other hand, Figure 3 is a view showing the appearance of the electromagnetic wave shielding net structure base station rack door according to this embodiment of the present invention, which is a frame of the same rectangular shape as the shape of the front part of the base station equipment rack (Lack) (Frame) (100) is formed, and an adhesive is applied to the inner space of the frame 100 and the mesh modular panel 300 of the network structure is inserted and formed. In this case, the material of the frame 100 is steel, the material of the mesh modular panel 300 is a conductive material including copper or nickel.

On the other hand, a pair of door hinges (Door Hinge 110) as shown in Figure 3 is installed on one side upper and lower portions of the frame 100. Therefore, the present invention is installed in a hinged manner in the base station equipment rack 1, which is possible to open / close.
