Dry Cooler for Immersion Cooling System for Avalon Miners

Dry cooler for an immersion cooling system in ASIC miners is a critical component designed to efficiently dissipate heat generated by high-performance mining rigs. Unlike traditional air-cooled systems, immersion cooling uses non-conductive fluids (e.g., mineral oil, fluorinated liquids) to directly cool ASIC chips, and the dry cooler acts as the external heat exchanger to reject this heat to the ambient environment.

Key Components

Tube Material: Stainless steel or copper tubes are preferred for corrosion resistance, especially when using glycol-based fluids or in harsh environments .

Fins: Aluminum fins with 5–20 mm spacing balance heat dissipation and dust resistance. Wider spacing (e.g., 10–20 mm) is suitable for dusty mining sites to reduce clogging .

Fans: Dual-speed or variable-speed fans adjust airflow based on heat load, minimizing noise (<55 dB) and energy use .

Control System: Integrated sensors monitor fluid temperature and ambient conditions, automatically adjusting fan speed and fluid flow to maintain optimal cooling
