Your GPUs are ready before your building is. L450C20 removes the building: 450 kW of training capacity in one factory-tested container — GB300 NVL72 / B300 HGX density, connected to power, water, and network in days, earning in 75–90 days on repeat orders. 机柜就绪往往早于土建。L450C20 用集装箱替代大楼： 单台工厂测试的集装箱提供 450 kW 训练容量 — 支持 GB300 NVL72 / B300 HGX 密度，数日接通电、水、网， 复购订单可在 75–90 天内创收。
You've seen the business case — modular blocks, BESS-first power, time-to-revenue. L450C20 is the Computing Unit in that equation: a 20-ft container with dual independent water systems. One loop supplies the GPUs at 36–45 °C through cold plates; a second chilled-water loop at 10/16 °C feeds in-row (CRAH) cooling for residual heat. Everything is integrated, tested, and sealed at the factory — on site you connect power, water, and network. 商业逻辑你已经看过——模块化区块、BESS 优先供电、投产时间。 L450C20 就是这个等式里的计算单元：一台 20 英尺集装箱，采用 两套独立供水系统。一路以 36–45 °C 经冷板服务 GPU； 另一路以 10/16 °C 冷冻水供给列间空调（CRAH）处理其余热负荷。所有系统在工厂 完成集成、测试与封装——现场只需接入电、水、网。
L450C20DR150IT Load vs. Facility Load. 450 kW is what the servers draw. Total facility load is higher once cooling and auxiliaries are added — the gap is set by PUE, which depends on your site's climate. *Cold, dry sites land at the low end. Always confirm which figure an "X MW" requirement refers to. IT 负荷与设施总负荷。450 kW 指服务器实际用电。计入冷却与辅助系统后， 设施总负荷更高——差值由 PUE 决定，而 PUE 取决于站点气候。 *寒冷干燥的站点落在区间下限。遇到「X MW」的需求时，务必确认指的是哪一个口径。
A cold plate in direct contact with the GPU carries heat out through water — supporting up to 150 kW/rack, the regime NVLink platforms require and air cooling cannot reach. Junction temperature stays precisely controlled under sustained training load. 冷板与 GPU 直接接触，靠水把热量带走——支撑 最高 150 kW/机柜，这正是 NVLink 平台所需、而风冷无法达到的区间。 在持续训练负载下，结温始终被精确控制。
L450C20 uses two water systems: a 36–45 °C loop for GPU cold plates (high-temperature, free-cooling friendly) and a separate 10/16 °C chilled-water loop for in-row CRAH units that handle residual rack and room heat. That split keeps GPU cooling efficient while air-side cooling stays on a classic chilled circuit. L450C20 采用两套供水系统：一路 36–45 °C 服务 GPU 冷板 （高温回路，利于自然冷却），另一路独立 10/16 °C 冷冻水服务列间空调（CRAH）， 处理机柜与室内余热。GPU 侧保持高效液冷，空气侧仍走经典冷冻水回路。
DLC adds real engineering — coolant loops, leak detection, redundant pumps. L450C20 absorbs all of it into one tested, standardized module. You get the density without owning the integration risk. 液冷确实增加了工程量——冷却回路、漏液检测、冗余泵。L450C20 把这些全部吸收进 一个经过测试的标准化模块。你拿到密度，却不必承担集成风险。
