In the daily operation of the data center, the cooling system has always been the main source of the energy consumption of non -IT equipment. The energy consumption of traditional air -cooled systems can often be close to half of the overall energy consumption of the data center. At the same time, with the development of high secrets and large -scale development, traditional cooling technology has difficulty meeting the heat dissipation needs of new data centers.

Therefore, more advanced refrigeration technology has become one of the core points of the construction of green data centers. The new data center refrigeration technology represented by cold plate -type liquid cooling, with higher cooling efficiency, can support higher power density and low requirements for data center computer room renovation, which has become the highest development direction in the industry.

From a professional perspective, the design reference of "Green Data Center Innovation Practice -Cold Plate System Design" has elaborated the concept, principles, and composition of the cold plate -type liquid cooling, and according to the needs of the actual application scenarios, how to solve how to calculate how to solve the solution The scheme and the chilled cold plate cooling accessories give a highly feasible reference suggestion.

Cold plate -type liquid cooling refers to the use of liquid as a heat transfer working quality in the inner flow channel of the cold plate, and the non -contact liquid cooling technology that cools the heat source to cool the heat source through heat transfer. In the cold plate -type liquid cooling system, the server chip and other heat devices do not directly contact the liquid, but to dissipate the cold plates that assembled on the electronic component that needed cooling. Therefore, this method has a small modification of the existing server chip components and affiliated components, and has a stronger operability. It has become the highest maturity and the most widely used liquid cooling solution.

"Green Data Center Innovation Practice -Design Reference of Cold Board and Cold Systems" revolves around the design of the entire link of the first side and the secondary side of the liquid cooling (see Figure 2), which can participate in the design, verification, pipeline pipelines participating in the cold plate heat dissipation system The engineering practice of connection assembly, system detection and maintenance personnel provides systematic reference and guidance.

Among them, the cold source of the cold -board liquid can use a mechanical refrigeration system and a natural cooling system. The mechanical refrigeration system includes the air-cooled and cold water system and the water cooling water system, which can provide a medium temperature frozen water at 12C-18 ° C. Natural cooling is the use of the cold amount of outdoor air without mechanical refrigeration without mechanical refrigeration when the outdoor meteorological conditions permitted. In the cooling process, the natural cooling system can be achieved using an open cooling tower, closed cooling tower and dry cold device, which can provide cooling water of more than 30C. The form of liquid cold source must be determined in conjunction with secondary end -end water temperature requirements and the outdoor environment of the project. The secondary liquid circuit refers to the design from the cold volume distribution unit to the rack, connecting the cooling industrial quality manifold to the IT device, and then returning the design of the cold volume distribution unit through the meter. The calories from the secondary cooling circuit are passed to the plate heat exchanger through the cooling volume to distribute the unit to the first -side cooling circuit, which is eventually discharged into the atmosphere or was recovered by the heat.

The design considerations of the cold plate system involve cooling work, cold board design, cold volume allocation unit (CDU), rack -type cooling work quality supply rebate, circulating pump, self -sealing fast -changing joint, secondary side pipeline path , Backboard air conditioning and other extensive content areas and design standards and specifications.
