AI Technical Summary
Existing data center cooling systems struggle to efficiently handle the high heat density demands of computing components. In particular, in high heat density computing devices, the high-speed flow of coolant can lead to corrosion and erosion of cold plates. Traditional cooling systems cannot economically meet the changing cooling requirements.
The intelligent refrigerant distribution unit (RDU) is used to achieve efficient heat removal by using two refrigerant cooling circuits through the R2RHX interface between the refrigerant cooling circuits. Combined with the subcooler and flow controller, it ensures stable flow of refrigerant in the cold plate and reduces the risk of corrosion.
It achieves efficient and low-power heat removal in high heat density computing devices, reduces cold plate corrosion, supports the cooling needs of edge data centers, avoids the shortcomings of traditional systems, and provides higher density cooling capacity.
