Immersion Cooling

Immersion Cooling – Immersion cooling is a heat dissipation technology that helps to maintain a stable and consistent operation of Bitcoin mining machines. This technology ensures that the Bitcoin mining equipment slowly cools down so that it can be easily used to mine Bitcoin.

In this setup, the mining equipment is immersed in a non-conductive liquid coolant that absorbs the heat generated by the hardware. This method of cooling is more efficient than traditional air cooling and can significantly increase the longevity and performance of mining equipment.

There are two types of immersion cooling: single-phase and two-phase. In single-phase immersion cooling, the liquid coolant remains in a liquid state and continually circulates to remove heat. In two-phase immersion cooling, the coolant changes state from liquid to gas and back to liquid to remove heat, capitalizing on the latent heat of vaporization for superior cooling performance.

The use of immersion cooling in Bitcoin mining can increase efficiency, reduce cooling costs, allow for higher hardware density (more miners in less space), and reduce noise levels compared to air-cooled systems.

Difference between Single-Phase and Two-Phase Immersion Cooling Systems

Immersion cooling can be implemented in two distinct forms: single-phase and two-phase systems, each with its unique mechanism for heat dissipation.

Single-Phase Immersion Cooling: In this system, the coolant remains in the same liquid state throughout the cooling process. The heat generated by the ASIC miners causes the liquid to increase in temperature. A pump circulates the heated liquid to a heat exchanger, where it is cooled and then returned to the tank. Single-phase systems are simpler and often less expensive to implement, making them a popular choice for many mining operations.

Two-Phase Immersion Cooling: Two-phase systems leverage the coolant’s phase change from liquid to gas and back to liquid to achieve cooling. As the ASIC miners generate heat, the liquid coolant absorbs this heat and evaporates, turning into a gas. This gaseous coolant then rises to a condenser, where it releases its heat and condenses back into a liquid. The condensed liquid is then returned to the cooling tank to continue the cycle. Two-phase systems are highly efficient at heat removal due to the latent heat of vaporization but are more complex and costly than single-phase systems.

Components of an Immersion Cooling System

An immersion cooling system comprises several key components, each playing a crucial role in its operation:

Together, these components form a highly efficient and effective cooling solution, capable of maintaining optimal operating conditions for ASIC miners, even under the most demanding workloads. Immersion cooling not only enhances the performance and longevity of mining hardware but also opens new possibilities for the design and scalability of cryptocurrency mining operations.

Benefits of Lianli’s Immersion Cooling Container

Achieve a PUE <1.02

PUE represents the ratio of the total energy used by a data center facility to the energy delivered to crypto mining equipment. Lianli Electronics allows you to achieve a certified PUE <1.02, improving your data center efficiency.

40% Hash Rate Increase

Air mines are prohibited from significant overclocking because of the ASICs’ thermal load. However, overclocking and fine-tuning for mines using immersion liquid cooling for mining allows for 40% higher hash rates. In addition, no fans or air handling results in less energy wasted.

Longer Equipment Lifespan

Increases hardware lifespan by 4-5 years by eliminating contamination, overheating, and corrosion. Air crypto mining farms are filled with airborne particles that are sucked into the heat sinks of each ASIC, which leads to overheating and a shortened lifespan. Immersion liquid cooling mining supports ASICs operating at maximum capacity for longer than ever.

100% noise and dust Reduction

Immersion cooling Bitcoin miners provide absolute noise reduction. This is because the fans, which are the primary sources of noise, are removed before immersion. Liquid-cooled Bitcoin miners are also dust-free. This increases the lifespan of equipment and saves the trouble of regular cleaning.

Smart Heat Utilization

Our immersion liquid cooling system for crypto mining has been conceived to reduce heat simultaneously with smartly recapturing and reusing that heat for other purposes, such as heating the space hosting the data center or the surrounding urban and industrial areas.

-50% Costs on CAPEX

Lianli Electronics immersion liquid cooling solutions are rapidly deployable in raw space without the need for raised floors. They can easily integrate into an existing data center or warehouse or even in an office with minimum retrofitting.

Wrapping Up!

The journey through the intricacies of ASIC immersion cooling reveals a technology poised to redefine the landscape of cryptocurrency mining. With its unparalleled efficiency in heat dissipation, immersion cooling stands as a beacon of innovation, addressing the perennial challenges of overheating, energy consumption, and noise pollution that have long plagued mining operations.

The key benefits of immersion cooling—enhanced cooling efficiency, reduced energy consumption, space optimization, noise reduction, and improved hardware lifespan—collectively contribute to a more sustainable, profitable, and environmentally friendly mining practice.

FAQs on Immersion Cooling

Q1. Why is Immersion Cooling more efficient than Air Cooling?

A: Liquid can be thousands of times more efficient than air in the transfer of heat, especially if it’s in motion.

• Dust and other particles do not accumulate in equipment
• Equipment is kept from overheating, allowing overclocking
• The container can sustain any extreme temperature

Q2. What are the operational benefits of Immersion Cooling?

A: Our solution increases hardware lifespan by 4-5 years by eradicating contamination, overheating, and corrosion. Most air mining farms are filled with airborne particulate matter, which is quickly sucked into the heat sinks of each ASIC. As a result, ASICs’ relative cooling capacity is drastically reduced, which leads to overheating and a shortened lifespan for the ASICs.

Q3. What liquid is used in immersion cooling?

A: Dielectric liquid cooling depends on the use of a thermally conductive but not electrically conductive fluid that will not disrupt the function of electrical components like servers. Examples of dielectric fluids include mineral oil hydrocarbons, synthetic fluorocarbons, and silicone fluids.
