Here’s how it works:
• Direct Contact with Cooling Liquid: Servers or other IT components are submerged directly into a non-conductive liquid. This liquid is dielectric, meaning it conducts heat but not electricity, so it won’t harm the electronics
• Efficient Heat Transfer: The thermal energy from the servers is transferred directly into the surrounding fluid. This method is more efficient than air cooling because liquids generally have better thermal conductivity than air
• Types of Immersion Cooling: There are two main methods: single-phase, where the liquid remains in the same state, and two-phase, where the liquid absorbs heat and changes to a gas state within the system
• Benefits: Immersion cooling systems are energy-efficient, reduce the need for space, and can increase the density of computing power in a data center. They also help in reducing noise and are considered more reliable due to fewer moving parts like fans or pumps
This cooling method is becoming increasingly popular as it allows for higher performance computing while reducing the carbon footprint and energy costs associated with traditional cooling methods. It’s particularly beneficial for high-density computing needs like AI, machine learning, and blockchain technologies.
An immersion cooling load bank is a device that simulates an electrical load specifically for systems that use immersion cooling technology. It’s designed to test the performance of power sources such as generators, batteries, or UPS systems within data centers that employ immersion cooling for their servers. Here’s how it functions:
• Heat Dissipation: It uses coolant-immersion elements to dissipate heat generated by the electrical load
• Testing and Validation: The load bank ensures that the immersion cooling system can effectively remove the heat generated by the data center’s electrical components
• Indoor and Marine Applications: Immersion load banks are suitable for indoor applications where noise and space are restricted, or for marine applications where seawater can be used as a coolant
• Integrated System Test (IST): It can simulate a data center’s electricity consumption, heat dissipation, air flow, and hot & cold aisle testing, providing independent verification of integrated system testing
These load banks are crucial for validating the reliability and effectiveness of immersion cooling systems in data centers, ensuring they operate correctly under the expected electrical loads.
