The owner's judgement作者判断

With 41–45 °C liquid cooling, the dry cooler rejects the plant's heat to outdoor air without a compressor. What do the main dry and adiabatic lines state, and can they make NVIDIA's 41 °C facility water?在 41–45 °C 液冷下,干冷器不用压缩机就能把冷站的热量排到室外空气中。主要的干式和绝热系列标称了什么?它们能造出 NVIDIA 示例的 41 °C 设施水吗?

Willow Lei · judgementWillow Lei · 判断

Over the next three years the dry cooler becomes the base-load machine of the AI plant: Kelvion has announced a contract worth more than USD 800 million to supply over 1,000 dry coolers for 5 GW of project heat-rejection capacity in 2027.

Yet dry coolers are bought on numbers nobody can compare: of 19 lines I checked, only three tie a capacity to fluid and air temperatures, and none of them is a complete single-unit rating.

The condition is ratings at the warm-water point (for example 46/41 °C fluid at 35 °C air) and a climate whose design day stays below that line, or adiabatic assist and its water use; where both hold, the dry cooler replaces the chiller as the plant's main machine.

未来三年,干冷器会成为 AI 冷站的基础负荷设备:Kelvion 宣布了一份超过 8 亿美元的合同,2027 年供应 1,000 多台干冷器,对应 5 GW 的项目排热容量。

但干冷器的采购依据的是无法相互比较的数字:我检查的 19 个系列里,只有三个把容量与液温和气温联系起来,而且没有一个是完整的单台额定值。

条件是厂商公布暖水工况下的额定值(例如 35 °C 空气下 46/41 °C 液温),且当地设计日气温低于这条线,或接受绝热辅助及其用水;两者都满足的地方,干冷器取代冷水机组成为冷站的主机。

Can a dry cooler make 41 °C water? The engineering reading干冷器能造出 41 °C 的水吗?工程解读

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
