接下来就是第三代,也就是现在从第二代往第三代走的这个过程中。那现在第三代的话,它是一个高压制流的方案。这个高压制流的话,它直接通过这个电源柜,然后去集成了所有的这个供配电的单元,包括像这个ACDC,然后包括像BPU,包括像超级电容等等的。 各位领导大家晚上好我是国金电信分析师宇文电那么我们最近是发布了AIDC系列深度的3那这篇深度报告的话我们主要想从未来行业的这个高压直流HVDC这块的这个切入去研究未来整个数据中心它的供电架构的这样的一个演变趋势 那我们这篇报告的话分为底下几个部分第一部分的话就是整个行业的背景还有就是各个企业他们现在海外大厂现在布局的这样的一个情况第二部分的话就是整个AIDC它的供电架构演进的一个路径分为海外跟国内的这样的一个分别去阐述然后第三部分的话就是关于供应商这边现在对于HVDC产品上面的布局 那首先是第一部分,那HVDC它之所以最近两年关注度比较高,主要还是因为整个AI的算力需求增长的比较快。那不管是从它的新增的耗电量的绝对额来看,还是说从它的这个占全球用电量的这样一个占比来看的话,未来整个数据中心这边的耗电的这个量以及它的输电效率都会比较影响整个的数据中心这边的成本。 特别是海外的 ...

Summary of IDC Industry Conference Call Industry Overview - The conference call focuses on the IDC (Internet Data Center) industry, discussing the performance and outlook of various companies within this sector [1][2][3]. Key Points and Arguments 1. **Market Correction**: Following Tencent's earnings report on March 18, the IDC sector experienced a significant market correction, with domestic stocks declining by 20% to 30% and U.S. stocks showing even larger adjustments, returning to early-year levels [1]. 2. **Earnings Pressure**: The overall profit and earnings outlook for the IDC industry is expected to be under pressure throughout 2023, particularly in the first and second quarters. However, 2024 is anticipated to be a year of significant bidding activity for the industry [2][3]. 3. **Bidding and Delivery Cycle**: The bidding process in 2024 is expected to see a notable increase compared to previous years. However, the transition from bidding to delivery and revenue realization involves a lengthy preparation period, often taking six months or longer [2]. 4. **Revenue Recognition**: Revenue realization is expected to be concentrated in the second half of 2023, with profitability requiring utilization rates to reach approximately 50% to 60% [3]. 5. **Impact of Capital Expenditure (CapEx)**: Concerns regarding a potential decline in overseas capital expenditures, particularly from major companies like Microsoft, have contributed to market volatility. However, recent reports indicate that major firms are maintaining their CapEx plans [3][4]. 6. **Microsoft's CapEx Stability**: Microsoft clarified that the cancellation of certain data center leases was a normal adjustment based on project selection and delivery conditions, rather than a sign of reduced capital spending [4]. 7. **H20 Procurement Impact**: The procurement plans of major internet companies may face slight impacts due to recent developments regarding H20, but overall, the previous year's bidding volumes are expected to remain unaffected [5][6]. 8. **Domestic Chip Acceptance**: There is an increasing acceptance of domestic chips among major internet companies, which is a positive development for the industry [6]. 9. **Positive Market Sentiment**: Recent media reports suggest potential new chip releases tailored for the Chinese market, which could positively influence market sentiment [7]. 10. **Valuation Recovery**: The IDC sector has seen significant valuation adjustments, with some companies trading at around 20 times EV/EBITDA. The potential for a rebound in the sector is viewed favorably, especially following recent market corrections [8][9]. Additional Important Content - The call highlighted the strong performance of IDC companies during periods of increased demand, such as during the pandemic, where valuations reached as high as 45 times EV/EBITDA [9]. - The overall sentiment towards the IDC sector is cautiously optimistic, with expectations for a rebound in stock prices as the market stabilizes [10].

环境专家警告，除了巨大的用水量外，数据中心冷却系统中的化学添加剂还可能污染地下水，造成长期 环境影响。 AI耗水量惊人 美国内华达大学拉斯维加斯分校建筑与城市规划教授Steffen Lehmann指出，传统大型数据中心每天可消 耗高达500万加仑水，相当于2万至5万人口城镇的日用水量。 当人们热议人工智能带来的电力消耗激增时，一个相对隐蔽但同样严峻的资源挑战正在显现——水资源 短缺。 随着AI技术快速发展，数据中心建设热潮背后隐藏着巨大的水资源消耗危机。市场情报集团Aterio的最 新研究显示，美国全国现有1827个活跃数据中心，另有1726个已宣布建设计划，419个正在施工中。 这些数据中心需要数百万加仑水进行冷却，其用水需求与AI支持设施的扩张同步增长。更令人担忧的 是，在面临水资源短缺的干旱地区，多个数据中心正在规划或建设中。在内华达、亚利桑那、得克萨 斯、犹他、加利福尼亚和科罗拉多等水资源严重紧张的州，就有437个数据中心在建或规划中。 据加州大学河滨分校和得克萨斯大学阿灵顿分校的联合研究，即使是相对简单的AI工作负载也需要大 量冷却水。 以ChatGPT为例，生成10到50个中等长度回应的耗水量相当 ...

AI云计算公司CoreWeave收购数据中心运营商Core Scientific的90亿美元全股票交易遭遇市场冷遇，两家公司股 价双双大跌。分析称，这凸显投资者对AI板块估值泡沫的担忧。 分析人士指出，Core Scientific股东的抛售行为反映出他们对CoreWeave股票作为支付手段的不信任，以及对这 家估值640亿美元、市销率高达13倍却尚未盈利的AI公司能否维持估值的质疑。 另外，这一异常的市场反应也暴露了AI热潮中部分公司估值过高的现实，也为当前创纪录的股市涨势敲响了警 钟。 股东用脚投票，交易溢价失去吸引力 Core Scientific股东的反应颇为罕见。通常情况下，当大公司提出溢价收购时，目标公司股东不会选择逃离。然 而，Core Scientific的市值已跌至60亿美元，比CoreWeave提供的股票价值低12亿美元，交易溢价率仍维持在21% 的高位。 据媒体报道，两家公司早在6月26日就开始谈判。在消息传出前，Core Scientific股价约为12美元，比目前水平 低约1美元。相比之下，收购方案最初对Core Scientific的估值约为每股20美元。 自7月7日宣布收购消息以 ...
