Case Study |Sailemer containerized cooling module helps Qingdao data center PUE break 1.233

The investment in the second phase of a communication data center project in Qingdao, China exceeds550 million yuan, planned AI computing power of 825PFlops, with business coverage extending to East China, Central China, and North China regions. 15000 racks will be deployed at the end of the project to provide a strong guarantee for the rapid development of Internet plus, cloud computing, big data and other emerging industries, and will become the largest five-star cloud data center in northern coastal China.

①BIM digital twin takes the lead in improving the utilization rate of computer room space

The customer's existing computer room layout cannot adapt to the new modelThe deployment of a 45kW cold plate liquid cooled cabinet requires modular design to release more space.Selemer utilizesBuilding digital models of electromechanical systems using BIM technology，Selemer utilizesBIM technology is used to construct a digital model of the electromechanical system, making the layout more reasonable, optimizing the length of pipeline layout, improving the utilization rate of machine room space, and reserving equipment installation positions for later expansion.

Selaimer innovatively adoptsThe bottom in and bottom out design facilitates the installation and maintenance of the pipeline system, and the appearance of the box is clean and beautiful after installation.

②Integrated module delivery to address the heat dissipation challenges of high-density computing power clusters

In order to address the heat dissipation challenges of high-density computing power clusters for customers, and toThe PUE value has been reduced from the original design value of 1.312 for the water-cooled air conditioning system to 1.233, and the overall design has been delivered by Thermo FisherCooling Hub containerized cooling module，The module mainly includes integrated circulation pumps, intelligent constant pressure water replenishment systems, nanoscale water treatment systems, as well as power supply and distribution, monitoring systems, connecting pipelines, valves, fittings, cables, fire protection, heating, air conditioning, ventilation, reserved pipeline interfaces, and other auxiliary supporting equipment for all equipment inside the box.

③Factory prefabrication production Rapid delivery to the site

The customer proposed a short construction period,The liquid cooling system renovation needs to be completed simultaneously in the second phase of the project, and the deployment window is too short.Sailaimer has compressed the overall on-site deployment cycle of pre galvanized seamless steel pipe components and other key equipment in the factoryDelivery within 45 days.Components and other critical equipment, the overall on-site deployment cycle is compressed toDelivery within 45 days.

✅ PUE breakthrough decline:Measurement of liquid cooling systemPUE 1.233， Reduced by 6% compared to the original design

✅ Spatial reconstruction capability:Modular design saves equipment floor space and reserves redundancy for expansionUE from 1.312

The energy efficiency transition of PUE from 1.312 to 1.233 once again proves the full chain capability of Thermo through 'digital design+factory prefabrication+intelligent pumping'，forThe 'East Calculation West Calculation' project aims to create a replicable green computing infrastructure design template.
