A cryptocurrency miner was looking for an air cooled solution for cooling an immersion fluid cooling bath. The operation has a 420 kW heat load coming from over 300 ASIC miners each releasing 1300 watts. Customer specified BitCool BC-888 dielectric fluid. This fluid can be as warm as 58°C (136.4°F). Using local weather data we determined an ambient air design temperature of 37.2°C (99°F) was acceptable. The 50°C bath temperature points to a simple Dry Cooler air cooled heat exchanger solution. A 3 fan AVI dry cooler along with a 100 GPM pump was selected.
