Description

Structure of the baffle plate mounted on the storage rack for telecommunications equipment}

The present invention relates to a structure of a baffle plate provided in a rack for storing communication equipment, and more particularly, to diagonally change cooling air flowing vertically from the bottom to improve cooling efficiency of communication equipment provided with a plurality of layers. Photo baffle plate is formed, the front cover inlet hole and the rear cover discharge hole is formed to prevent the cooling air that has been changed to high temperature after cooling the communication equipment to heat the communication equipment again, and the baffle plate to improve the coupling force of the baffle plate A pair of baffle fixing protrusions to be fixed are formed, and a structure of a baffle plate provided in a rack for communication equipment storage having a rotating fan to increase the pressure of inlet and outlet cooling air.

In general, computer rooms such as electronic computing rooms of corporations, banks, schools, buildings, laboratories, laboratories, and telephone exchanges are equipped with communication equipment (eg, network equipment, servers, communication exchangers, etc.), and a large amount of heat is generated in these communication equipment. This occurs, the room temperature always increases, but if it is not cooled, there is a risk of malfunction of communication equipment due to overheating. Therefore, a separate air conditioner must be used to maintain the room at an appropriate temperature.

Therefore, most computer rooms are equipped with air conditioners such as air conditioners and constant temperature and humidity chambers to properly cool the rooms to maintain appropriate temperatures.

In addition, the communication equipment provided in the computer room is installed inside the rack for communication equipment, the communication equipment rack is a mechanism for mounting various communication equipment such as a communication exchanger, a server, network equipment and the like inside.

The conventional technology of cooling the computer room is to install a plurality of air conditioners toward the edge of the computer room and operate the air conditioner to cool the communication equipment.

However, since the cold air discharged from the air conditioner only cools the air around the air conditioner, the cold air is supplied only to the communication equipment in close proximity to the air conditioner, and it is very difficult to supply the cold air to the communication equipment in the central part of the computer room. .

Therefore, the air conditioner operation had to be made stronger to cool the communication equipment located in the center of the computer room, thus increasing the amount of cooling energy consumed.

On the other hand, the "rack having a cooling and heating function" according to the Republic of Korea Patent Publication No. 10-2008-0020277 is disclosed.

The rack having a cooling and heating function according to the publication number 10-2008-0020277 is a cooling and heating control unit and a communication unit operating based on signals detected by various sensors such as a heating and cooling device, a temperature sensor, a humidity sensor, etc. in the rack. By employing, it is a technology for transmitting the abnormal temperature generated inside the rack to the outside, and to adjust the internal temperature by measuring the temperature inside the rack.

However, a rack having a cooling and heating function according to Publication No. 10-2008-0020277 requires a heating and cooling device, a sensor, an air conditioning control unit, and a communication unit for each rack, thus requiring a lot of installation and maintenance costs. There is a problem that can not be used when cooling the entire computer room by providing a plurality of communication equipment racks rather than a communication equipment rack.

Here, Figure 1 is a view showing the cooling of the communication equipment rack in another conventional method as shown in Figure 1 to form a space (F) on the bottom surface of the communication equipment rack (R) provided in the computer room In addition, the method of supplying the cooling air (A) through the lower surface of the communication equipment rack (R) through the space portion (F) is executed.

However, the conventional method for cooling the communication equipment rack is another communication in which the cooling air (A) is changed to a high temperature after cooling the communication equipment (S) located at the lowest floor located on top of the communication device (S) By cooling the equipment (S) again, there is a problem that the communication equipment (S) located at the top is not cooled.

The present invention was devised to solve the problems of the prior art as described above, and an object of the present invention is to form a baffle plate provided to be inclined inside the baffle body so that the cooling air vertically introduced from the lower portion moves diagonally. The cooling air changed to high temperature after cooling the communication equipment by forming the front cover inlet hole and the rear cover discharge hole which greatly improves the cooling efficiency of the communication equipment provided in the layer of the communication equipment and is supplied to one side and discharged to the other side. It prevents heating of communication equipment again, forms a pair of baffle fixing protrusions to fix the baffle plate to improve the bonding force of the baffle plate provided inside the baffle body, and rotates the perforated part where the cooling air is introduced or discharged. A fan is attached to the rack for communication equipment to raise the pressure of the inlet and outlet cooling air. To provide a structure of the provided baffle plate.

In order to achieve the above object, the structure of the baffle plate provided in the rack for storing the communication equipment according to the present invention is cooled by the communication air generated from the cooling air supplied from the cooling device provided in the lower space of the bottom surface to generate heat. The baffle plate is provided in the communication equipment storage rack to induce the movement direction of the cooling air so that the baffles provided on both sides of the communication equipment storage rack so that the cooling air flowing from each communication equipment storage rack is blocked.
