Description

Prefabricated modularized data center roof seam sealing node and data center Technical Field The utility model relates to the technical field of prefabricated modularized data centers, in particular to a prefabricated modularized data center roof seam sealing node and a data center. Background The prefabricated modularized data center is a pre-engineered scheme product which integrates information technology equipment (such as a server, a switch, a firewall and the like), matched power supply and distribution equipment, refrigeration equipment, fire protection equipment, monitoring equipment and the like into a modularized box body in a factory according to project requirements, and then transports the box body to a project site for splicing and stacking. The method has the characteristics of short construction period, high flexibility, stable construction quality and the like, and gradually becomes the mainstream trend of the data center building. Waterproof and heat preservation in roofing practice is one of the most important factors affecting the function of construction, and is also a weak link in construction. The data center is internally provided with a large amount of high-value and precise equipment, is sensitive to the environment and is high in price, so that roof waterproofing and heat preservation are particularly important for prefabricated modular data center projects, and once waterproofing fails or heat preservation effects are poor, equipment damage or operation energy consumption is increased, and loss and consequences are serious. The prefabricated modularized data center is formed by splicing and stacking different module containers, and the sealing effect of the roof splice directly determines the waterproof and heat-insulating performances of the roof. The existing design concept of the sealing scheme of the roof splice is to realize the waterproof and heat preservation by different materials respectively, the synergistic effect among the different materials is poor, the sealing structure of the splice is complex, and the waterproof and heat preservation performance gradually declines with time.
