• Immersion Cooling: This involves submerging the entire server or IT equipment in a dielectric liquid. The liquid absorbs the heat generated by the components, and the heated liquid is then circulated through a heat exchanger to dissipate the heat. Immersion cooling offers excellent cooling performance and can support extremely high-density computing.
• Rear-Door Heat Exchangers: These systems attach to the back of server racks and use liquid-cooled heat exchangers to remove heat from the exhaust air. Rear-door heat exchangers are a less intrusive option compared to direct-to-chip or immersion cooling and can be retrofitted into existing data centers.
• Liquid-to-Air Heat Exchangers: These systems use liquid to transport heat from the servers to a heat exchanger, where the heat is then dissipated into the air. Liquid-to-air heat exchangers combine the benefits of liquid cooling with the familiarity of air cooling, making them a popular choice for many data centers.

Each of these liquid cooling methods offers unique benefits and trade-offs in terms of cooling performance, cost, and complexity. The choice of which system to implement depends on the specific requirements of the data center, including the density of the computing infrastructure, the available space, and the budget.
