一直很纠结,不知用什么作为水冷介质,百度了一下,大多偏向蒸馏水,但蒸馏水有很多,选哪一种呢,然后无意中发现了这样的一篇文章:

| 电导率（μS/cm） | 电导率（百分比） | 电阻率（MΩ/cm） | 电阻率（百分比） | 价格（ml/元） | |
| 18.2MΩ超纯水 | 0.055 | 0.04 | 18.2 | 23.48 | |
| 溶解有空气的纯水 | 0．5~1 | 0.39~0.78 | 1~2 | 1.28~2.56 | |
| 怡宝纯净水 | 1.29 | 1 | 0.78 | 1 | 269.23 |
| 屈臣氏蒸馏水 | 1.37 | 1.06 | 0.73 | 0.94 | 186.67 |
| 娃哈哈纯净水 | 1.56 | 1.21 | 0.64 | 0.82 | 350 |
| 百事冰纯水纯净水 | 2.24 | 1.74 | 0.45 | 0.58 | 500 |
| 大峡谷纯净水 | 2.89 | 2.24 | 0.35 | 0.45 | 500 |
| 自制去离子水 | 4.38 | 3.40 | 0.29 | 0.37 | |
| 康师傅矿泉水 | 16.79 | 13.02 | 0.06 | 0.08 | 611.11 |
| 清洁淡水 | ＜100 | ＜77.20 | ＞0.01 | ＞0.008 | |
| 自来水 | 270 | 20.93 | 0.0037 | 0.004 | |
| 海水 | ＞10000 | ＞7752 | ＜0.0001 | ＜0.0001 |
总结：
综合纯净程度、价格和易购买程度，怡宝纯净水无疑是胜者，而不少人推荐的屈臣氏蒸馏水则稍逊一筹，当然他们的纯净程度都是在同一个等级的，不过显然在价格和易购买程度上就比不上怡宝了。他们的水质已经不错了，接近溶解有空气的纯水，可以认为这两者加上娃哈哈是处于第一阶梯的，后面的就是第二阶梯了。大峡谷的价格不错，也容易买，就是水质有限。值得注意的是。矿泉水的话并不像我们平常说的那么糟糕，离子浓度还是可以接受的（嗯，想了一下，估计是厂家特地控制的，毕竟如果你买来一瓶矿泉水发现里面出现水垢你会有何想法），用作水冷也并非那么不堪（我第一次做去离子水的时候电导率都20μS/cm），还是可以接受的。
后记
浓缩液加纯水 , 纯水一定时间后会腐蚀金属设备,所以需要加一定量的抗腐蚀金属的物质，抗水藻，抗泡沫，冷冻不需要，南方天，抗氧化，抗电耦合
