The evolution history of mining rigs from air cooling to oil cooling and then to liquid cooling. Why are liquid cooling mining rigs the trend?

In the field of cryptocurrency mining, the cooling technology of mining rigs has evolved from air cooling to oil cooling and then to liquid cooling. Each transformation is of great significance. Let's explore the mysteries behind this!

Air cooling: The origin of mining rig cooling

In the early days, mining machines had a low hash rate. Air cooling uses fans to make air flow and remove heat. This cooling method has low site costs and is easy to install and maintain. However, air conducts heat poorly and makes much noise, disturbing people easily and making it hard to hide. If the environment is highly humid or dusty, the machines are prone to damage. Moreover, as the hash rate of mining machines increases, their power consumption becomes higher and higher. Traditional air cooling methods can't handle such a large amount of heat generated. In the era of high hash rates, mining machines that lack advantages in hash rate and energy efficiency ratio will gradually be phased out.

Oil cooling: An attempt to break through difficulties

As the hash rate soars, air cooling can no longer cope, and then oil cooling comes into play.

Mining machines are immersed in insulating coolant for heat dissipation, which is known as immersion oil cooling. This method features high heat dissipation efficiency, short circuit prevention, and a noise-free operation.

However, it's not easy to control the temperature. High temperatures can damage the chips. The oil on the circuit boards is difficult to clean, which makes maintenance inconvenient. Moreover, if the venue's protective measures are inadequate, it may even lead to a fire.

Liquid Cooling: Pioneering a New Trend

Nowadays, liquid cooling has become the new favorite for mining machine cooling. It dissipates heat by sending coolant through pipes, boasting extremely strong heat dissipation capabilities. Additionally, it can customize liquid channels according to the layout of mining machine chips, presenting significant advantages. On one hand, this cooling approach is energy-efficient and quiet. On the other hand, it doesn't require a large volume of cold air for the heat dissipation of mining machines. In this way, it prevents the damage to mining machines from dust and water vapor, greatly extending their service life. Especially for cold-plate liquid cooling, its heat dissipation is more direct and effective. It can quickly carry away the heat from the chips, preventing chip damage caused by high temperatures and reducing the number of maintenance times for mining machines.

The reasons for liquid cooling trending toward the future.

I. Performance Advantages: A high hash rate causes mining machines to generate a large amount of heat. Liquid cooling can ensure the stable operation of mining machines, maintain a high hash rate, and increase mining profits.

II. Cost Considerations: Cost considerations: Although the initial investment is high, in the long run, it saves a lot of energy and cuts down electricity bills. Also, it reduces malfunctions and maintenance costs.

III. Environmental Requirements: The coolant is more eco-friendly. Also, it operates with low noise, which meets environmental requirements.

IV. Technological Innovation: Liquid cooling technology is constantly evolving. Its modular and integrated design makes installation and maintenance more convenient. It also has strong scalability, enabling it to meet the needs of mining farms of different scales.

V. Waste Heat Recovery: The heat generated by servers can be recovered and utilized in various scenarios, such as fishery, bath center, breeding base, hotel, indoor heating, and drying.

The cooling technology for mining machines is evolving continuously. Liquid cooling, with its numerous advantages, is leading the future trend!
