Description

Technology Field

[0001] The present invention relates to an immersion cooling system, and more specifically, to an immersion cooling system using a thermal image and a control method thereof, which measures the temperature distribution of cooling fluid inside an immersion cooling tank using a thermal image and generates bubbles (or air bubbles) inside the immersion cooling tank based on this to rapidly cool a server. Background Technology

[0003] Immersion cooling is a technology that uses liquid to cool electronic devices such as servers (or data servers). Instead of traditional air cooling methods, more effective heat dissipation and energy efficiency can be achieved by immersing servers or data center equipment in insulating fluid. This technology is particularly useful in high-performance computing or large-scale data centers and is a field receiving increasing attention due to the recent rise in demands for improved energy efficiency and sustainability in data centers.

[0004] In particular, in high-density server environments, heat can be controlled with significantly less space and resources than air cooling, greatly reducing energy consumption and lowering the cost of using fans or air circulation systems. As a result, overall power consumption decreases, leading to reduced operating costs.
