先说液冷。 今日液冷板块延续强势，龙头英维克在全市场超4000家下跌的悲观情绪下逆势涨停。我们认为今天 液冷板块强势除了前些日出海订单持续超预期的催化外，还与今天字节资本开支信息发酵相关，毕 竟明年起，国内液冷市场将也会呈现爆发增长。 目前国内的超节点都是液冷的形态，除了曙光是浸没式液冷，其他都是冷板式液冷。 这里再补充一点H200的事， 假如H200最终放开，那进到国内的基本都是8卡机，都是风冷的 ；包括 国内厂家的8卡机，也都是风冷为主。 大家对国内液冷市场盈利能力的担忧主要来源于与国内储能液冷市场的横向对比，认为液冷技术门 槛有限，在国内比较卷的商业环境下难有好的利润率。国内经商环境比较卷这点并否认，但储能液 冷与数据中心液冷在应用及适配门槛上差距还是比较大，从适配周期来看，数据中心液冷适配周期 显著长于储能液冷，数据中心液冷新供应商导入周期短则1年，长则2-3年，而储能液冷新供应商导 入最快速度平均在3-6个月，本质还是赛道成熟度及终端产品用途差异所致。国内数据中心液冷的毛 利，对于成本管控能力较强的液冷厂商，可以做到25%左右。 关于昇腾链，也就是国产链，我本来计划元旦前写一篇关于明年的展望时，分析 ...
