Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of curtain wall, and particularly relates to a curtain wall structure of the outer facade of a data center. BACKGROUND

[0002] A data center, commonly known as a computer room, is a complete set of complex facilities. It not only includes computer systems and other supporting equipment (such as communication and storage systems), but also contains redundant data communication connections, environmental control equipment, monitoring equipment, and various security devices. With the rapid growth of the scale and number of data centers and the implementation of the double carbon target, the requirements for energy saving of data centers are also becoming higher and higher. In recent years, indirect evaporative cooling air conditioning units have been widely promoted and applied in data centers as an efficient, energy-saving and reliable refrigeration solution. The air inlet effect of the indirect evaporative cooling air conditioning unit is a key factor to meet the heat exchange of the unit. In order to avoid the influence of the exhaust shaft on the air inlet when arranged in multiple layers, a curtain wall is usually not arranged between the exhaust shafts, and a curtain wall is arranged on the outer facade of the data center. The traditional scheme adopts an aluminum hole plate curtain wall, but the aluminum hole plate curtain wall has the following disadvantages when applied to the outer facade of the indirect evaporative cooling air conditioning unit system:

[0003] 1. Poor ventilation: The surface material of the traditional aluminum hole plate curtain wall is a ribbed punched aluminum single board. Due to its own material properties, its ventilation rate cannot break through 50%-60%, which limits the air inlet volume of the air conditioning equipment and directly affects the refrigeration effect;

[0004] 2. Long construction period: All components of the traditional aluminum hole plate curtain wall are custom-made and need to be processed two months in advance. The equipment needs to be in place before installation, so the construction period is long. If there is a temporary change in equipment layout, it is difficult to adjust, and it is necessary to re-produce, which is time-consuming and labor-intensive and delays the construction period;

[0005] 3. Poor corrosion resistance: The surface aluminum plate of the traditional aluminum hole plate curtain wall is anodized, and the color is single. If the exterior decoration is painted with colored fluorocarbon, the paint on the edge of the punched aluminum plate will crack, which is common. It is easy to corrode in high humidity and high temperature difference conditions and difficult to repair;

[0006] 4. Poor detachability: The traditional aluminum hole plate curtain wall cannot be opened and ventilated in large areas due to the self-weight of the plate structure. If large equipment needs to be transported in and out, the curtain wall can only be disassembled layer by layer according to the plates, columns and beams. Large-scale exterior wall operation equipment needs to be used, the disassembly area is large, and the curtain wall cannot be perfectly restored due to the combination of processes.

[0007] 5. High cost: The traditional aluminum hole plate curtain wall is evolved from the original glass curtain wall. The force transmission structure, such as embedded parts, adapters, horizontal main beams, vertical load-bearing columns, secondary beams, reinforcing frames, louvers, and ribbed punched aluminum panels, is complex and has a high cost (usually 600-800 yuan per square meter).
