作者：Wade去年 6 月份我们在《中国闲置比特币矿机或超 200 万台 解封暂不乐观海外“救火”需再等半年》一文中对国内闲置矿机数量进行了估算，当时我们认为由于国外矿场建设周期较长、建设成本较高、出海手续复杂等原因，会有大批矿机闲置。时至今日，矿主们对海外矿场建设的手续、选址等方面已经摸索出了一些经验。但现实是 2022 年没有多少矿场实际通电，漫长的矿场建设时间和高昂的建设成本以及部分地区政策的不稳定性、电价和环境的波动仍然是困扰矿主们的主要问题。已经在落成的矿场，也面临新的难题。伊朗在今年 6 月份宣布因电力供应紧张切断了境内矿企的电力供应，且目前尚未公布恢复供应时间。哈萨克斯坦也于今年 7 月份签署了对加密矿工征税更高税率的法案。这些问题使矿主们对矿场迁移能力的需求大幅提升，而土建矿场则成了一种低效且高风险的选择。在此背景下，很多矿场开始采用集装箱方案来解决问题。矿机集装箱相较土建矿场最明显的优势就是节省矿场建设的成本，包括时间成本、人力成本等，具有时间周期短、便于迁移、高效、低成本的优势。除建设成本外，矿主们还需考虑矿场的运营情况，尤其是温度、湿度、电力供应等因素。但不幸的是，由于近年来全球气温持续升高，很多地区居民和企业用电屡创新高，多地电网无法保证稳定持续的电力供应，影响了矿场的正常运行，并且高温还是导致矿机发生故障的主要原因之一。目前安全可靠的能源资源大多集中在北美，因此冷却能力和合规性也是矿主要考虑的重点问题。就冷却能力来说，液冷方案相较风冷方案来说更具优势，且具有超频挖矿、无噪挖矿、延长矿机使用寿命、同等算力下功耗更低等优点。目前市场上的液冷方案主要分为抽屉式小单位液冷柜和水冷分体式集装箱两种。其中抽屉式液冷柜受到技术水平的限制液冷集装箱机位数量往往只能做到 8-10 台。且该方案一般不配备冷却系统，需矿主自行配置。而水冷分体式集装箱一般售价较贵，单机位性价比不高。以某公司产品为例，其官网售价为 110,000 美元，虽可搭载 210 台 S19 Hydro 系列机型，但该机型并非市场上主流的机型，在不计算运费、其他成本的前提下平均机位成本达 523.8 美元。矿主如果采用这种水冷方案，就必须配备价格昂贵的水冷矿机。此外，其集装箱与冷塔还需分别运输，将造成双倍的运输成本，安装流程上也较为复杂。
