How to Maintain a Bitcoin Immersion Cooling System After Installing a Dry Cooler?

Regularly inspect for leaks: Conduct a leak check on the dry cooler's piping system every six months. The procedure involves first shutting down the user-end load equipment, then stopping the dry cooler unit for maintenance. After leak detection, promptly replenish the system if any coolant loss is detected.

Maintain fin cleanliness: Dust accumulation on dry cooler fins reduces heat dissipation efficiency. Clean fins 2-3 times with detergent, then blow dry with compressed air. Adjust cleaning frequency based on dust levels, typically every 3-6 months.

Inspect fans and oil pumps: Regularly check the operational status of fans and oil pumps to ensure fans operate normally with sufficient airflow and oil pumps deliver coolant stably. If abnormal noise, vibration, or speed deviations are detected in fans or oil pumps, immediately shut down the unit for inspection, troubleshooting, or replacement of damaged components.

Monitor coolant condition: Regularly test coolant parameters including appearance, acid value, dissipation factor, and dielectric constant. During the first year of operation, sampling frequency should be every 6 months; after stable operation, annual testing is sufficient. Simultaneously, establish a monitoring mechanism for coolant usage and consumption. Replenish coolant promptly. For single-phase immersion liquid cooling systems, the annual operational loss rate of the cold-side coolant should be kept below 3%. For two-phase immersion liquid cooling systems, the annual operational loss rate of the cold-side coolant should be kept below 5%.

Filter Cleaning: Dry cooler filters prevent foreign objects from entering the cooling system, which could clog heat exchange tubes or impede coolant flow. Regularly inspect filters and clean or replace them based on clogging levels to maintain coolant cleanliness.

Electrical Connection Inspection: Periodically inspect all electrical connections on the dry cooler to ensure secure fastening without loosening, oxidation, or damage. Simultaneously, verify the insulation integrity of electrical equipment to prevent leakage accidents.

Calibrate sensors: The accuracy of temperature, pressure, and other sensors on the dry cooler is critical for system operation. Have sensors calibrated annually by a professional testing agency to ensure reliable and precise measurement data.
