Dry Cooler of Bitcoin Mining Equipment Immersion Cooling System

In the immersion cooling system of Bitcoin mining equipment, the dry cooler is a crucial component for heat dissipation, and its working principle is as follows:

Heat Exchange Mechanism

Primary Heat Exchange: In the immersion cooling system, the mining equipment is immersed in a non - conductive liquid. When the equipment operates, it generates heat, which is absorbed by the non - conductive liquid, causing its temperature to rise. The hot non - conductive liquid is pumped to the dry cooler. Inside the dry cooler, there are heat exchanger tubes through which the hot non - conductive liquid flows. Outside the tubes, ambient air is blown by fans. Heat is transferred from the hot non - conductive liquid inside the tubes to the ambient air outside through the tube walls, achieving the first - stage heat exchange.

Enhanced Heat Exchange: To improve the heat exchange efficiency, the heat exchanger tubes in the dry cooler usually have a large surface area and a special structure. For example, they may be finned tubes. The fins increase the contact area between the tubes and the air, allowing more heat to be transferred to the air. At the same time, the fan nozzle design in the dry cooler is optimized to maximize the air flow and air throw, ensuring that the air can fully contact the heat exchanger tubes and take away the heat.

Fan Control and Energy Saving

Adaptive Fan Speed Regulation: The dry cooler is equipped with an adaptive fan controller. The controller monitors the temperature of the non - conductive liquid or the ambient temperature. When the temperature of the non - conductive liquid rises or the ambient temperature is high, the fan speed is increased to enhance the heat dissipation effect. When the temperature is relatively low, the fan speed is reduced to save energy and reduce noise. For example, in the ICP15 dry cooler, the fan speed is controlled by an adaptive fan controller, which can make the fan operate as quietly as possible while ensuring the heat dissipation effect.

In summary, the dry cooler in the immersion cooling system of Bitcoin mining equipment uses the heat exchange between the heat exchanger tubes and the ambient air to dissipate the heat generated by the mining equipment, and realizes energy - saving operation through fan control, which plays a key role in ensuring the normal operation of the immersion cooling system and the stable operation of the mining equipment.
