Ore Box Liquid Cooled Miner Renovation Technology Oil Cooled

Product Description

At present, under the circumstance that the currency price has shrunk sharply, miners who want to continue mining, while considering the currency price and the price of the machine, in order to comply with the trend of "dual carbon" energy saving and environmental protection, they should also consider more secure and stable mining. The mining method, the traditional air-cooled mining will produce a lot of noise pollution, the second is the uninterrupted operation mode, which will cause waste of natural cooling sources, which is not conducive to energy saving and environmental protection. It is stable, and liquid cooling can solve these problems well. At the same time, a cooling liquid return mechanism can be set up to connect the absorbed heat to the building heating system and water supply system, which not only improves the cooling efficiency of the data center, but also realizes the utilization of waste heat. , created added value.

1,The basic principle of liquid cooling mining is that the heat generated by the power calculation board of the mining machine is transferred to the oil during use, and the oil exchanges heat through the heat exchanger to maintain the temperature of the mining machine at a low temperature.

2,Liquid cooling and heat dissipation are divided into immersion liquid cooling and cold plate indirect liquid cooling. Our company mainly aims at the transformation of mining machines for immersion liquid cooling and provides corresponding services for transformation. The first thing is to deploy immersion liquid cooling mining chassis. The size and standard capacity are shown in the figure:

The transformer oil required for the standard box is 78l (Great Wall No. 10 transformer oil or No. 25 transformer oil can be used, or Dow Corning DC dimethyl silicone oil). The whole machine includes two temperature controllers, heat exchanger components, several interfaces, etc. customers need to buy cooling oil, circulating water pump, cooling tower and other items by themselves.

3,According to different miner models, the number of miners that can be put is different

For example: models with 4 mining machines, such as S19, S17, s17+, T17, S15, S11 of ant, etc

Models with 8 mining machines, such as ant S9, Shenma m21s, and Shenma M21

5,Description of external water source mode:

Method 1: if there is well water or river water around the site, only one submersible pump is required, as shown in the figure:

Method 2: if there is no water source, use cooling tower circulating water, as shown in the figure:

(special note: after our test, the temperature of most mining machines is the most stable when the flow rate is 3l/min (single set), and the average temperature is 38 ℃). When the flow rate is 2l/min, the temperature of the liquid cooling box is 42 ℃, indicating that the faster the flow rate is, the lower the temperature is. The cooling tower is divided into 3T, 5T, 10t, 20t and 100t. According to 3l/min, the conventional 10t cooling tower (about $150) can carry 56 mining machines.

6,Reference notes on experimental data:

(1) Flow rate test:

Test liquid volume 80L, test model 4 ants s17+ 76t, ambient temperature 31 ℃

When the flow rate is 6.9l/min:

After one hour, the temperature reaches a stable value, and the upper liquid level temperature is 38.7 ℃

Circulation temperature 34 ℃

The average temperature of background PCB is 55 ℃

When the flow rate is 4l/min:

After one hour, the temperature reaches a stable value, and the upper liquid level temperature is 37.8 ℃

Circulation temperature 34.7 ℃

When the flow rate is 3l/min:

After one hour, the temperature reaches a stable value, and the upper liquid level temperature is 39.9 ℃

Circulation temperature 34.9 ℃

When the flow rate is 2l/min:

After one hour, the temperature reaches a stable value, and the upper liquid level temperature is 42.6 ℃

Circulation temperature 37.8 ℃

It can be seen that the best circulating flow rate is 3l/min

(2) About overclocking

For many mining machines, there is no modified silicone grease for heat dissipation, and soaking in oil will produce dissolution reaction. The original silicone grease will dissolve in about 15 days, so we need to use our customized cooling silicone grease, with a service life of about 3 years. As shown in the figure:

Among them, 3W is ordinary and 8W is custom heat conduction, and the overclocking heat conduction cooling is very fast. If the original miner does not have thermal conductive silicone grease, there is no need to modify our thermal conductive silicone products. For example, the original ant S17, S15, S11, S9. For example, in S19, some series of Shenma need to modify our silicone gasket, otherwise the force calculation board is easy to break.

(3) About installation test:

The company provides remote guidance and on-site installation guidance (travel expenses need to be reimbursed); Provide customers with mining machine testing and ash removal services.
