2、Facility water systems often requiredGrowing pressure to improve PUE and meet sustainability goals Increased Compute Density=Thermal Challenges Hybrid Approach:Combines liquid cooling with existing air-cooled setups.Modular&Scalable:Fits within standard data center layouts,supporting IT expansion.En

3、hanced Reliability:Redundant and hot-swappable components ensure continuous operation.Built for High power GPUs within High-Density Racks:Enables cooling of up to 240kW Sidecar cooling solution advantages Key components:Cooling power:240kWSidecar dimensions:120cmx120cmx230cmCondenser surface area 35

4、,300cm2DeploymentNo rack redesign neededCondenser housed within sidecarPlug and play installationSupport redundancy and hot swapping Sidecar configuration SidecarRPURPU80%less pumping power vs.single phase due to the minimal liquid flow needed(0.3LPM for every 1kW)Space saving-the low flow rate allo

5、ws the use of a smaller condenser sizeCondensation is more effective than reducing liquid temperature due to tighter temperature differentials.The use of aluminum microchannel(compered to copper fin and tube):Improves heat transfer performance,resulting in greater overall condenser efficiency.Allows

6、 the use of a smaller condenser size Lower air side pressure dropLighter material and less internal liquid volume Two-Phase Sidecar Cooling benefits Two-Phase Loop:Liquid absorbs heat vaporized condensed recirculatedClosed System:No facility water requiredNo leak risk near electronicsSmart Controls:
