Can a dry cooler make the 41 °C facility water of NVIDIA's reference example?干冷器能造出 NVIDIA 参考示例中 41 °C 的设施水吗？
Data as of 2026-10-13, reviewed monthly.数据截至 2026-10-13，每月复核。Condition: ratings at the warm-water point, and climate or adiabatic assist前提：按温水工况公布额定值，并满足气候条件或接受绝热辅助
Cooled fluid leaving冷却后流出的液体Hot fluid from the plant来自冷站的高温液体Drawn from BAC's public documents; not an engineering drawing.依据 BAC 公开资料绘制，并非工程图。
Dry coolers are sized in vendor selection software; a catalogue kilowatt without fluid and air temperatures cannot be compared. None of the three rated points is a complete single-unit rating.干冷器通过厂商选型软件配置；没有液温和气温的样本千瓦数无法比较。三个有工况的点都不是完整的单机额定值。
Lines that tie a capacity to fluid and air temperatures把容量与液温和气温挂钩的系列
Air at or below which the two points with a leaving temperature could still make 41 °C water: Kelvion 31 °C (approach 10 K), Baltimore Aircoil (BAC) 35.4 °C (approach 5.6 K)两个写明出液温度的点，在不高于此气温时仍可造出 41 °C 的水：Kelvion 31 °C（接近温差 10 K），Baltimore Aircoil (BAC) 35.4 °C（接近温差 5.6 K）
Dry coolers in Kelvion's announced contract: more than USD 800 million, for 5 GW of project heat-rejection capacity in 2027Kelvion 公布的合同中的干冷器台数：超过 8 亿美元，用于 2027 年 5 GW 的项目排热能力
Over the next three years warm water widens the dry cooler's role in the AI plant, alongside the chiller rather than in its place.
未来三年，温水让干冷器在 AI 冷站中的作用更大，但它与冷水机组互补，而不是取代冷水机组。
With 41–45 °C liquid cooling, the dry cooler can reject the plant's heat to outdoor air without a compressor whenever the air is cool enough; the chiller covers the rest.在 41–45 °C 液冷下，只要室外空气足够凉，干冷器不用压缩机就能把冷站的热量排到室外；其余时段由冷水机组承担。
NVIDIA's reference example supplies 41 °C facility water to the CDUs. A dry cooler's leaving fluid sits a few kelvin above the outdoor air (its approach). Engineering reading, not a vendor statement: from each rated point, the air temperature at which that unit could still deliver 41 °C water at the same approach. Approach changes with flow, fan speed and selection, so this is a screen, not a rating. The reading assumes the dry cooler feeds the CDUs directly; with an intermediate heat exchanger, subtract that exchanger's approach as well.NVIDIA 的参考示例给 CDU 供 41 °C 的设施水。干冷器的出液温度比室外空气高几 K（接近温差）。以下是工程解读，不是厂商声明：按每个额定点，估算在相同接近温差下仍能供 41 °C 水的空气温度。接近温差随流量、风机转速和选型而变，因此这只是筛查，不是额定值。该解读假设干冷器直接给 CDU 供水；如有中间换热器，还要再减去该换热器的接近温差。 NVIDIA sourceNVIDIA 来源
