What is immersion cooling for ASIC miners?

In an ASIC submerged cooling system, a portion of the cryptocurrency bitcoin miner, usually the arithmetic board, is submerged in a dielectric coolant to keep the ASIC chip cool and extend the power efficiency and life of the machine. Traditionally, miners "air-cool" the machine by using ventilation fans and special HVAC systems to adjust the miner to keep the chip temperature low.

This dielectric coolant is a man-made fluid with massive thermal conductivity and zero electrical conductivity. The main premise behind its use is that it cools the arithmetic plate faster because the fluid has a greater heat transfer capability than air. Mining operations using immersion systems are primarily concerned with the optimal flow rate of fluid through the arithmetic plate to keep chip temperatures low.
