A water cooling system using the whole building appeared in Bitcoin's mining facility

A virtual currency on the Internet "Bitcoin(Bit coin) ", you can" mining "a new coin by doing" mining "with a dedicated program, so the situation to raise machine specs and minimize as many bit coins as you canArms raceIt has reached a level that can be safely said. The cutting edge of such Bitcoin mining is no longer a dimension of amateurs entering with play.

Visit of ASICMINER's Immersion Cooling Mining Facility

This is Xiaogang Cao. Chinese version of cloud funding siteDreamChinaIn this time, Mr. Friedcat, ASICMiner's CEO who specially develops hardware dedicated to bit coins, said that he was permitted to interview the company's equipment.


This is the inside of the machine room. There are not much differences between the machine racks and the normal room, but when you look closely you can see that the rack is divided into three parts in the top and bottom, each containing milky box-shaped items.


Actually, this box is a fish tank, and the board dedicated to the bit coin has become a tank that cools the heat generated by the mining operation at high speed with liquid coolant.


Here is an example of a board that is submerged in a tank. A dedicated ASIC chip was mounted for each tankBlade Erupter BladeThe unit which carried 92 pieces is contained. Since the processing capacity of this "Blade Erupter Blade" is about 12.8 GH / s (12 GH hash per second), it is about 1.18 TH / s for one unit.


Here is the figure that fits in the tank. Each board is connected with a connecting cable.


Cooling water made by 3M company is used for the tank. It is said that very expensive cooling water is used and the water temperature is constant at almost 37 degrees.


From the board, bubbles generated by heat are coming up.




Each rack is surrounded by piping that supplies cooling water, just like a factory or research facility. Because it is water cooled, it is said that the working sound is quite small and quiet. The weight per rack has reached 200 kg.


On the roof of the building, this is also a large-scale one that is also installed with dedicated cooling facilities. This facility is located in a corner of Hong Kong's industrial area and it was said that it was built from August to November this year.



The system is still being developed, and in the future it is also possible to turn mobile type ones. It is thought that systemization can be carried out by placing it on a truck and moving it just by connecting it to a power supply and a network, and in a cold district it is supposed to use diagonally that it can be used for heating by using heat generation .

As you can see, in terms of bit coin excavation, you can understand the current situation that amateurs are no longer able to catch up even if they start with a light feeling. The total number of bit coins that can be distributed is set at 21 million, and the number of coins excavated at the end of November 2013 is about 12 million. As the remainder becomes fewer, the hurdle for excavation is going to rise, so the competition for digging out about 9 million bit coins will further increase momentum and imagine that the performance required for hardware will also continue to increase It is not difficult situation.
