Containerized Immersion Cooling for Bitcoin Miners Cooling

Containerized Immersion Cooling for Bitcoin Miners Cooling

1. Containerized Modular Design

High-Density Integration: A single container can accommodate 192 Antminer S19 or 240 Whatsminer M50 mining rigs, enabling rapid deployment through standardized design. For example, the BC20 Mega container features eight independent cooling tanks, each connected to a dry cooler via an independent circuit, enabling concurrent maintenance without disrupting overall operations.

Space Optimization: Mining rigs are vertically immersed in coolant, saving approximately 40% of machine room space and eliminating the air conditioning system required for traditional air cooling, further reducing space requirements.

2. Immersion Cooling Technology

Direct Heat Exchange: Mining rigs are completely immersed in a fluorinated liquid or mineral oil, which directly absorbs heat from the chips (with a thermal conductivity 1,600 times that of air). For example, a single-phase coolant, driven by a circulating pump, forms a closed circuit between the rigs and the dry cooler, maintaining a stable chip temperature below 60°C. Phase Change Enhanced Heat Dissipation: After absorbing heat, the two-phase coolant boils and evaporates. The vapor condenses into liquid in the dry cooler and flows back into the system. This utilizes the latent heat of vaporization (approximately 2260 kJ/kg) for efficient heat dissipation, resulting in a 30% improvement in efficiency compared to single-phase systems.

3. Key Functions of the Dry Cooler

Waterless Cooling: The dry cooler dissipates heat through air convection, eliminating the need for an external water source. It is particularly suitable for arid regions and is suitable for mining sites of varying sizes.

Intelligent Temperature Control: A variable frequency fan and PID algorithm dynamically adjust cooling power. It operates completely dry at ambient temperatures between 15°C and 30°C, and activates spray-assisted cooling above 35°C (using only 10% of the water consumption of traditional cooling towers).
