Description

Technical Field

[0001] The utility model belongs to the technical field of ventilation, and in particular relates to a ventilation device for a communication room. Background Art

[0002] During the operation of communication equipment, some equipment will generate high voltage and static electricity, which will attract dust in the air. The dust will carry moisture and corrosive substances into the equipment and cover the electronic components, causing the heat dissipation capacity of the electronic components to decrease. Long-term accumulation of large amounts of heat will cause the equipment to work unstably. In addition, since the distance between the chip angles and circuits on the printed circuit board is quite small, generally in the mm and μm level, when the computer room environment is humid, dust will cause the insulation resistance of adjacent lines in the printed circuit board to decrease, or even short circuit, affecting the normal operation of the circuit, and in severe cases, even burning the power supply, motherboard and other equipment components.

[0003] The national standard has the following requirements for the dust concentration in the air of the main engine room: when tested under static conditions, the number of dust particles greater than or equal to 0.5μm per liter of air should be less than 18,000 particles. In order to meet the dust requirements of the machine room, the fresh air fans installed in the general communication machine room are designed with filters. However, when the dust concentration in the ambient air outside the machine room is high, the filter in the fresh air fan is under great pressure and needs to be replaced regularly. The filter in the fresh air fan is expensive on the one hand, and replacing the filter in the fresh air fan is cumbersome, time-consuming and labor-intensive on the other hand. Utility Model Content

[0004] In order to solve the above problems, the utility model provides a ventilation device for a communication room.

[0005] The utility model is implemented as follows: a ventilation device for a communication room includes a fresh air blower, the fresh air blower is connected to an air inlet pipe and a return air pipe indoors, the fresh air blower is also connected to an outdoor air inlet pipe, a filter installation hole is provided on the outdoor air inlet pipe, a filter is provided inside the outdoor air inlet pipe, the filter includes a frame, the frame matches the inner diameter of the outdoor air inlet pipe, the frame is connected to a filter bag, a top plate is provided on the upper part of the frame, a threaded hole is provided on the top plate, threaded holes are also provided around the filter installation hole on the outdoor air inlet pipe, and the top plate is firmly connected to the outdoor air inlet pipe through screws. Outdoor fresh air in the communication room enters the fresh air blower from the outdoor air inlet pipe through the filter, and is then transported by the fresh air blower to the equipment room or the monitoring room of the communication room. Since most of the dust can be removed by filtering the outdoor air through the filter, the pressure of the fine filter inside the fresh air blower can be greatly reduced.

[0006] Furthermore, a sealing gasket is provided between the top plate and the surface where the outdoor air inlet pipe cooperates. The sealing gasket can effectively prevent the air from escaping in the outdoor air inlet pipe, avoid increasing the working pressure of the air supply fan in the fresh air fan, and prevent the outdoor air with high dust content from entering the fresh air fan.

[0007] Furthermore, the frame is provided with support columns, which can effectively improve the strength of the frame and facilitate the frame to be installed in the outdoor air inlet duct.

[0008] Furthermore, the fresh air fan is provided with a blower, an exhaust fan, a heat exchanger and a fine filter. The blower provides air supply power in the fresh air fan, and the exhaust fan exhausts the air in the communication room. The outdoor fresh air passes through the filter and the exhaust air of the communication room completes heat exchange in the heat exchanger to recover the indoor cold or heat. The heat-exchanged air passes through the fine filter and enters the equipment room and the monitoring room after meeting the dust prevention requirements of the room.

[0009] Furthermore, the power of the supply fan is greater than that of the exhaust fan. The fan power is greater than that of the exhaust fan to ensure positive pressure inside the computer room and avoid negative pressure in the computer room. Unpurified air from the outside is sucked into the computer room through gaps in loosely sealed windows and doors, causing the dust cleanliness in the computer room to seriously exceed the standard, affecting the life of network equipment and causing failures.

[0010] Furthermore, the air inlet duct is connected to the first air outlet and the second air outlet, the air return duct is connected to the first return air outlet and the second return air outlet, the first air outlet is arranged at the lower part of the equipment room, the second air outlet is arranged at the upper part of the monitoring room, the first return air outlet is arranged at the upper part of the equipment room, and the second return air outlet is arranged at the lower part of the monitoring room. This design is conducive to the air circulation between the equipment room and the monitoring room, and ensures the ventilation effect.

[0011] An underground air duct is arranged at the bottom of the equipment room, the first air outlet is arranged in the underground air duct, an anti-static plate with holes is arranged above the underground air duct, and the communication equipment is placed above the anti-static plate. By setting up the underground air duct, the air inlet of the equipment room enters from the bottom, passes through the anti-static plate, passes through the communication equipment, and returns to the upper part, which is conducive to the effective ventilation of the communication equipment.

[0012] The beneficial effects of the utility model are as follows: the utility model has a reasonable structural design. First, a filter installation hole is opened on the outdoor air inlet pipe, a filter is arranged inside the outdoor air inlet pipe, and the filter bag on the filter is used to remove most of the dust, which can greatly reduce the pressure on the fine filter screen inside the fresh air fan; second, a threaded hole is opened on the top plate of the filter, and the filter and the outdoor air inlet pipe are firmly connected together by screws, which is convenient for disassembly and assembly. When the filter needs to be replaced, it only needs to remove the screws on the top plate of the filter and replace it. The operation is simple, saving time and effort.
