Best Bitcoin Miner for Immersion Liquid Cooled Bitcoin Mining
Picking the correct miner is crucial if you want to scale your Bitcoin mining operations using immersion technology. Efficiency is key in the bitcoin mining industry, and immersion liquid cooling is quickly becoming a game-changer. Immersion cooling provides a high-performance solution that maximises hash rates and extends the lifespan of mining equipment, which is crucial for Bitcoin miners who are facing increasing electricity costs, hardware deterioration, and thermal inefficiencies. Under terms of how well they perform under liquid immersion, though, not all ASIC miners are the same.
Discover which Bitcoin miners work best with immersion liquid cooling, how efficient they are, and how well they adjust to this state-of-the-art cooling approach in this comprehensive guide.
What is Immersion-Cooled Bitcoin Mining?
Immersion-cooled Bitcoin mining is a submerging mining equipment in a pool of dielectric (nonconductive) fluid, usually made up of oils or synthetic liquids, which is called Bitcoin mining, or just “immersion.” This is done to increase productivity, lower noise, get other benefits, and, most importantly, get rid of the heat that the ASIC miners produce. Instead of using fans to move air around the miners and lower their temperature, this method is different from the standard air-cooled method.
Essence of Cooling in Bitcoin Mining
Bitcoin mining uses a huge amount of power because it takes a lot of computation to turn electricity into hashes that are used to verify transactions and earn bitcoin rewards. It is necessary for this process to quickly get rid of the large amount of heat that it produces.
Miners use two main types of cooling to keep their equipment from getting too hot: air cooling and immersion cooling.
One of the most important things for miners to do to keep their operations running smoothly and reliably is to manage their heat well. If they don’t, too much heat can cause them to use more electricity and be less productive. The hotter a miner runs, the more likely it is that something will go wrong.
Benefits of Immersion
- Increased Efficiency: Liquid coolant used in immersion allows for more efficient heat transfer since fluids have a higher thermal conductivity than air. This can reduce the overall cost of running the miners, excluding the additional expenses required by immersion.
- Higher Hash Rate: With improved cooling, mining hardware can operate at higher performance through overclocking to produce more hashes, leading to a higher chance of earning block rewards (i.e., bitcoin).
- Reduced Power Consumption: Immersion can help reduce the power consumption of miners, as the preinstalled fans and/or other parts of the miners can be removed.
Types of Immersion Cooling
Single-Phase, Single-Loop Immersion
The first type of immersion, single-loop immersion, usually has a cylinder with a cooling fluid in it and a pump that moves the fluid around. The fans are taken away before the miners are put in because they are no longer needed. The miners’ heat moves from the ASICs to the fluid and out of the system. Once the fluid is cool, it goes through a radiator or heat exchanger, which is either cooled by air or water, based on how it is set up.
Single-Phase, Double-Loop Immersion
Today, double-loop immersion cooling is the most popular way to use immersion on a large scale. It is the second generation of immersion mining setups. It is a more complicated device with two loops that move fluid around. In the first loop, which is like single-loop immersion, the miners are immersed in a liquid coolant that takes in heat and sends it to a heat exchanger. The second loop uses a different liquid coolant, like water or a mix of water and glycol, that comes into direct contact with the coolant in the first loop. The second coolant takes in the heat from the first loop coolant and sends it to a cooling tower or chiller to be released. If you use this method, the secondary coolant can get rid of heat better than the main coolant alone, which makes the cooling higher efficient.
Two-Phase Immersion
Two-phase immersion cooling has a lot of benefits. First, it might lower the cost of buying mines because more parts can be taken off than with single-phase immersion. Because two-phase immersion is better at transferring and cooling heat, it allows for a higher heat density. This means that more mines can be stacked close together, which could save 5 to 10 percent of the power used by single-phase immersion. This technology is still new, though, and it costs more and needs to be maintained more often than single-phase immersion sets.
