Immersion cooling for ASICs and mining farms: liquid

Mining farms working on special ASIC chipsneed a rather complex ventilation system. Otherwise, the equipment will work with less productivity or will not last very long.

What it is?

Various cooling methods are used to create comfortable conditions. Recently, they began to use immersion cooling. For this, the blocks are immersed in a liquid that does not conduct current. This cooling method is called immersion cooling. The whole point is that the substances used for this are inert, therefore it is permissible to place devices connected to electricity in them.

Immersion cooling for ASICs and video cards

Cooling Difficulties mining farm some of the most pressing. Overheating of the structure can lead to the most unpleasant consequences. But if we are talking about devices with small, 5-15 kW, then it is permissible to use household air conditioners, but if we talk about industrial farms that consume power from 50 kW to several MW. In this case, immersion cooling technology comes to the rescue for S9… Let’s try to figure out how it works?

Immersion cooling ASIC refers to the process of removing heat from operating equipment by immersing it in a container filled with immersion fluid. This technical liquid has a specific patented formula. Advantages of the liquid:

1. Non-flammability;
2. Low toxicity;
3. Passivity;
4. Dielectric parameters.

T. about. this liquid does not enter into any chemical reactions, with any substances and, in fact, is an absolute dielectric and this allows it to be used with any electronic equipment, without any consequences for the latter.

Note! The use of this fluid does not pose a hazard to any equipment and people who work with it. Most users after installing a liquid bath accelerate ASICs by 10-25%.

The use of these fluids in industrial volumes began many years ago. In ours, it is used to create cooling systems in data centers and mining farms. Historically, when building a new mining farm, up to 35% of the costs are spent on cooling equipment, of the costs of operating it, almost 50% falls on the cooling system.

• Research carried out on a regular basis shows that immersion cooling has a high energy efficiency (PUE).

There is a mineral oil for immersion cooling. This method is used to cool transformers and other equipment.

With the use of technology Novec 7200, 1230. This is dry water used for two-phase cooling.

Powered by 3M Novec 7300, 7500 technology and other fluids used for single-phase cooling. It takes place due to the constant mixing of warm and cold layers of liquid.

The basic types of immersion cooling used for ASICs and mining farms are listed. The choice of any particular one depends on certain factors. Technologies based on the use of dry water show the utmost efficiency.

How to assemble a cooling bath with your own hands

To ensure the operation of an industrial mining farm, it is enough to purchase ready-made equipment. It can be found on specialized resources dedicated to cryptocurrency mining equipment. But for those who mine at home, artisanal conditions, overheating is a serious problem. In a short time, the air temperature will cease to be comfortable. This pushes home miners to create immersion cooling for ASICs with their own hands.

Experience has shown that the simplest solution is to use an aquarium. In principle, you can use any ready-made container, such as a plastic box or box. Another thing is that it is required to ensure the circulation of the liquid, that is, it is required to cool the heated liquid and return it to the working container. To solve this problem, you will have to use a circulation pump, a heat exchanger, for example, a brazed heat exchanger. To avoid clogging of the coolant circulation system, you will need to install a strainer.

• To create such a structure, it is permissible to use polypropylene pipes with DN 16.

The connection diagram may look like the following.

Cold tap water is supplied to the heat exchanger on one circuit, and water from the tank is supplied to the other circuit. Under the action of the pump, water from the tank passes through a filter, a heat exchanger, where it gives off excess heat and returns back. Tap water, having received excess heat, can be sent to the sewer or to heat the house.

disadvantages

Like any technical design, immersion cooling has a number of disadvantages, in particular:

• High price. The thing is that the maintenance of such a structure can cost at least 25% of the cost of maintaining the farm as a whole. That is, if the installed farm consumes 10,000 rubles of energy. The cost of cooling will amount to 2,500 rubles. Cooling fluid is not cheap.
• The container for the immersion liquid opens only from the top and therefore it is unlikely that it will be possible to assemble the farm on racks.
• When carrying out preventive maintenance, liquid can get on the floor, and it is difficult to wipe it off.
• It is required to ensure filtration of the working fluid. This will avoid sediment and dirt build-up.

Benefits

Refrigeration equipment manufacturers promise that there will be a reduction in electricity costs. Savings can be up to 90%, according to Allied Control.

• The use of an immersion cooling design allows the placement of miners in close proximity to each other, that is, it is permissible to install 10 times more devices on the same area.
• Such a cooling design for 8 ASICs will help to overclock the device to its maximum power.
• The immersion liquid eliminates the possibility of dust and other contaminants getting inside the devices, thus reducing the possibility of overheating and the depletion of the device.
• This liquid is safe for equipment and people.
• The liquid cooling system does not generate noise during operation.

Conclusion

While the cryptocurrency is in demand, technical progress has gone far ahead, and if a few years ago a traditional desktop computer was wooed to generate, the cooling of which was provided by a cooler, then nowadays, when the computing power has seriously increased, serious solutions are required, immersion cooling is one of the them. The use of this method will save equipment and reduce energy costs.
