　    阿里云优惠券 先领券再下单        传统数据中心因依赖风冷技术，能源使用效率(PUE)普遍在1.5以上，导致大量电力被用于散热而非计算本身。面对“双碳”目标与可持续发展的紧迫需求，RAKsmart凭借其创新的液冷技术，成功将数据中心的PUE降至1.2以下，为行业树立了绿色标杆。    数据中心能耗困境与液冷技术的崛起    数据中心的能耗主要由IT设备、制冷系统和供电损耗构成。    

On the night of the first GOP presidential debate, as Donald Trump’s political rivals discussed immigration, abortion, China and education, the absent former president’s campaign shared a slew of policy videos. At first blush, the move might seem to be an unremarkable attempt to stay in the discussion. But among the agenda items aimed at ending the “nightmare” of homelessness, protecting students from liberal ideology “infecting educational institutions” and a plan to “restore law and order” was a proposal with a sharper edge – one for eliminating prosecutions as we know them.
The choice was curious for a candidate who is also a defendant facing criminal processing on Thursday – one who has been warned as a condition of release not to do anything that could be construed as intimidating witnesses, co-conspirators or basically anyone in the legal system. And it highlights the narrow space between Trump’s political messaging and threats of retribution he has been prohibited from delivering.
In the video, dubbed “Firing the Radical Marxist Prosecutors Destroying America,” Trump pledges to “restore the scales of justice in America” and end the “weaponization” of the justice system at the hand of “Marxist local district attorneys,” with a plan to overhaul the Justice Department and order investigations into district attorneys, while appointing 100 U.S. attorneys who will be the “polar opposite” of those he says are destroying the rule of law.
“As we completely overhaul the federal Department of Justice and FBI, we will also launch sweeping civil rights investigations into Marxist local District Attorneys,” Trump said, claiming the prosecutors had engaged in illegal selective enforcement.
The video – part of Trump’s broader Agenda 47, a loose collection of priorities if he were to win the White House and become the 47th president that Trump also shared on social media Wednesday night – was initially released on April 13. That was the day he appeared for a deposition in New York in a case brought by Attorney General Letitia James, who has for years been among the foremost targets of Trump’s ire. But it also mirrors language Trump has used to disparage Atlanta District Attorney Fani Willis, who brought the charges in an election interference case to which Trump is expected to surrender on Thursday.
The former president, who insists he has done nothing wrong, is set to be booked on the charges after his legal team agreed to his release conditions earlier this week. Among the conditions, which are far more voluminous than those agreed to by the other defendants, Trump must not intimidate co-defendants, witnesses, unindicted co-conspirators, any victim, the community or property within the community, or “otherwise obstruct the administration of justice.” The order stipulates that such intimidation – “no direct or indirect threat of any nature” – includes posts on social media or reposts of posts made by others on social media.
The social media restriction is notable given Trump’s penchant for plentiful posts about those who he says have wronged him. Since the agreement, signed on Monday, Trump’s rhetoric about the case has appeared to dwindle. Even so, he shared a video from Georgia Lt. Gov. Burt Jones on Wednesday that claimed Willis had “funneled millions of taxpayer dollars into her self-serving pursuits,” while Atlanta’s crime “goes unchecked.” And on Monday, hours after the agreement, Trump balked at his upcoming arrest by the “radical left district attorney.”
The issue has arisen in other cases the former president faces as well, including in the Jan. 6 case where prosecutors sought a protective order after Trump appeared to make comments related to the case in a post on social media, in what they argued was part of a pattern of the former president posting about ongoing cases – and sometimes going after judges and attorneys in the process.
Meanwhile, Trump’s surrogates have maintained pressure on Willis, as they have in the other cases he faces, like on Thursday when the House Judiciary Committee opened an investigation into the district attorney, claiming that her pursuit of the charges against Trump is politically motivated, and requesting documents related to the case.
It’s likely part of a strategy Trump will employ going forward, as his speech comes under the microscope, while he tests a fine legal line in the march toward four criminal trials amid a presidential campaign.
。风冷技术通过空气循环散热，但存在两大瓶颈：一是空气比热容低，需消耗大量电能驱动风扇;二是难以应对高密度服务器集群的热量堆积。

二 | 据统计，全球数据中心年耗电量已占全球总用电量的2%-3%，其中40%以上用于散热。    液冷技术通过液体直接或间接接触热源，其导热效率是空气的1000-3000倍，成为突破能耗瓶颈的关键。RAKsmart将浸没式液冷与冷板式液冷技术融合，打造出新一代智能散热系统，从根本上重构数据中心的热管理逻辑。RAKsmart的液冷方案已在美国硅谷、新加坡等20余个超大规模数据中心部署。    RAKsmart液冷技术的核心创新    浸没式液冷：重塑服务器散热架构    RAKsmart采用单相浸没式液冷方案，将服务器完全浸入绝缘、无腐蚀性的氟化液(如3M Novec)中。液体通过直接接触CPU、GPU等高发热元件，迅速吸收热量，并通过外循环系统将热能导出。相比传统风冷，该技术降低散热能耗达90%，同时允许服务器在更高功率密度下运行(可达50kW/机柜)。    冷板式液冷：精准控温的模块化方案    针对部分无法全浸没的场景，RAKsmart研发了微通道冷板技术。通过贴合在芯片表面的定制化冷板，冷却液以层流状态带走热量，温差控制在±0.5℃以内。

三 | 结合AI驱动的流量调节算法，系统可实时匹配算力负载，实现“按需冷却”。    余热回收与能源循环系统    RAKsmart独创的热能回收管道，可将60℃的冷却液余热转化为办公供暖、热水供应甚至吸附式制冷能源，使数据中心从“能源黑洞”转变为区域综合能源站。

四 |     PUE<1.2背后的系统工程    实现超低PUE不仅依赖散热技术创新，更需全局优化：    供电架构革新：采用高压直流(HVDC)供电与锂电储能系统，将电能转换损耗从传统UPS的10%降至3%。    AI能效管理平台：通过数万个传感器实时采集温度、湿度、负载数据，动态调整制冷功率。

五 | 在低负载时段，系统可自动切换至“节能模式”，PUE最低可达1.08。    气候适应性设计：在寒冷地区部署自然冷源利用系统，全年90%时间无需机械制冷，直接通过外部空气冷却循环液。    综上所述，RAKsmart的液冷技术不仅是散热方式的革新，更标志着数据中心从“能耗大户”向“绿色引擎”的范式转变。欢迎访问RAKsmart网站，获取定制化的解决方案。
