Unraveling the Oil Cooling System in Bitcoin Mining Machines

Traditional cooling systems in electronics, including air and basic liquid cooling, face challenges when it comes to dissipating the enormous heat generated by advanced Bitcoin miners. Here’s where immersion cooling, particularly oil cooling, becomes a game-changer.

What is Immersion Cooling?

It’s a cooling practice where electronic components are submerged in a thermally conductive dielectric liquid or coolant. In the case of Avalon A1246I, this coolant is a special mineral oil.

Why Oil?

Oil has an inherently high capacity to absorb heat. It’s non-conductive, which means there’s no risk of short-circuiting the electronics. The chosen mineral oil for A1246I ensures that the components are kept cool and safe.

The Process

•Immersion: The Avalon A1246I mining components are immersed in this mineral oil.
•Heat Absorption: As the machine operates, heat is generated by the chips. This heat is directly absorbed by the surrounding oil, raising the oil’s temperature.
•Circulation: Oil, being denser than air, can absorb more heat in a given volume. As the oil near the components warms up, it naturally circulates, allowing cooler oil to come into contact with the heated components.
•External Cooling: The warmed oil is then pumped out to an external system where it’s cooled down, often using a radiator or other heat-exchange systems.
•Return Loop: Once cooled, the oil is circulated back into the immersion tank, and the cycle repeats.

Advantages of Oil Cooling System

•Efficiency: Directly absorbing heat from the source ensures minimal thermal resistance, leading to better cooling efficiency.
•Safety: The non-conductive nature of mineral oil ensures the components are safe from electrical hazards.
•Prolonged Hardware Life: With effective heat management, the life span of the mining machine components is extended.
•Quiet Operation: Unlike air-cooled systems with fans, oil immersion systems are near-silent.
•Space-saving: No need for extensive air ventilation systems, allowing for a more compact mining setup.

Monitoring Temperatures

For A1246I, it’s essential to keep tabs on the oil temperatures. With an inlet temperature of 40℃ and an outlet temperature of 64°C, the system ensures that the temperature differential aids in effective heat exchange.
The Avalon A1246I represents the confluence of mining power and sophisticated cooling. The oil cooling system isn’t just an ancillary feature; it’s at the heart of ensuring that the machine operates optimally, safely, and efficiently. As the crypto-mining arena heats up with competition, such innovations in cooling will play a pivotal role in determining the success and longevity of mining operations.

Water Cooling: A Dive In

Water cooling utilizes a closed-loop system where water, or a water-based solution, circulates through pipes, coolers, and pumps to absorb and dissipate heat.


Efficient Heat Transfer: Water has a high heat capacity, making it efficient at moving heat away from components.
Flexible Design: Water cooling systems can be designed to fit tight spaces and can be expanded easily.
Prolonged Hardware Life: Effective heat management with water cooling can extend the life of electronic components.


Potential for Leaks: Water can be damaging if leaks occur, risking damage to electronic components.
Maintenance: The system requires periodic maintenance to prevent issues like algae growth or corrosion.

Comparative Snapshot: Oil vs. Water Cooling

Efficiency: Both systems offer high efficiency, with the choice often boiling down to specific requirements and constraints.
Safety: Oil cooling edges out due to its non-conductive nature, ensuring no risks of electrical mishaps.
Maintenance: Oil cooling might require more frequent maintenance due to potential oil degradation, while water cooling systems need checks for leakages and blockages.
Flexibility: Water cooling provides more flexibility in design, especially for constrained spaces.
