Why is Data Center Cooling Crucial in the Age of AI?
The rapid advancement of artificial intelligence (AI) has brought about extraordinary innovations across various sectors, from healthcare to autonomous vehicles. However, this massive computational power presents significant new challenges for data center infrastructure, particularly concerning temperature management. AI applications process a wealth of data, requiring advanced hardware like specialized AI chips that consume more power and, in turn, generate a lot more heat. Without effective cooling strategies, this heat can lead to inefficiencies and potential system failures.
Data centers in Indonesia, much like those worldwide, are now facing an urgent need to adopt more sophisticated cooling technologies. Data from the International Energy Agency shows that data centers globally account for approximately 1% of the total electricity demand—a figure comparable to the annual electricity use of entire countries like Australia or Mexico. This indicates that while the 1% figure may sound modest, its impact is substantial. In the context of AI, this energy consumption is set to grow exponentially. Therefore, it is crucial for data center operators to understand the heat intensity they are dealing with and how to control it.
Proper temperature management is not merely about “putting out a fire”; it is a strategy to unleash the full potential of AI without being consumed by the challenges associated with AI data centers. By mastering the right cooling methods, companies can continue to innovate and advance their AI applications. A key element in this temperature management is the Distributor Cooling Data Center which provides the advanced solutions needed to handle these high heat densities.
Unique Challenges in AI Data Center Cooling
AI data centers have unique challenges that set them apart from conventional data centers. High-density computing infrastructure using advanced AI chips like AMD’s Instinct MI250X and NVIDIA’s H100/H200 can generate 20-100+ kW per rack. This extreme power density far exceeds the capabilities of traditional air-based cooling.
Some of the primary challenges faced by AI data centers in Indonesia include:
- Insufficiency of Air Cooling: Conventional air cooling methods are often inadequate for some AI data center scenarios, leading to inefficiencies and potential downtime.
- Need to Accommodate Higher Density: Data center designs must be able to accommodate high-density deployments, which require more robust and efficient cooling solutions.
- Navigating Standard vs. Non-Standard Designs: The rapid evolution of data centers necessitates flexibility in design to accommodate different types of hardware and configurations, some of which may not conform to existing standards.
Fortunately, there are many proven and effective cooling methods, though not all are suited to the specific challenges of an AI data center. Innovative solutions from a Distributor Cooling Data Center like Climanusa offer extraordinarily efficient ways to address these issues, ensuring IT infrastructure operates at optimal temperatures.
Types of AI Cooling Technologies
To tackle the significant heat challenges, modern AI data centers in Indonesia are adopting various advanced cooling technologies. These technologies can be broadly categorized into two main types: air-based and liquid-based cooling.
Air-Based Cooling
While conventional air cooling may be insufficient for high densities, advanced air-based cooling methods still play a vital role. These involve using containment systems such as Cold Aisle Containment (CAC) and Hot Aisle Containment (HAC).
- Cold Aisle Containment (CAC): This system isolates cool air within specific aisles to prevent it from mixing with hot exhaust air. This ensures the cool air only goes to cool the IT equipment, enhancing cooling efficiency.
- Hot Aisle Containment (HAC): HAC works by trapping hot air in the aisles, allowing cool air to reach the equipment more efficiently. These methods allow for more efficient cooling and are optimal for high-performance environments with densities up to 50 kW per rack.
Liquid-Based Cooling
For handling more extreme power densities (up to 100 kW per rack), liquid-based cooling becomes a more effective solution. The two primary methods in this category are Direct Contact Liquid Cooling and Liquid Immersion Cooling. Climanusa, as a leading Distributor Cooling Data Center in Indonesia, provides the advanced cooling units that support these technologies.
- Direct Contact Liquid Cooling (DCLC): This method uses a Cooling Distribution Unit (CDU) to directly extract heat from critical IT components, such as chips. DCLC creates a ‘technology loop’ that separates the heat generated by the IT equipment from the coolant system, ensuring efficient heat removal directly at the source. This technology can be deployed in conjunction with air-cooled equipment or for a dedicated vault.
- Liquid Immersion Cooling (LIC): In this method, IT components, including servers, are fully submerged in a dielectric (non-conductive) fluid. This fluid safely absorbs heat from the entire surface of the components, including chips and motherboards, ensuring uniform and direct cooling. LIC is highly efficient and significantly reduces energy consumption in data centers.
How Liquid-Based Cooling Works
A liquid-based cooling system operates through three primary loops:
- The Primary Loop: The liquid coolant, typically chilled by a rooftop chiller plant, is circulated through a ‘cold supply loop.’ This coolant then supplies cooling to the data center, either through traditional air-based methods (with fan-coil walls or Computer Room Air Handlers (CRAH)) or directly to a Cooling Distribution Unit (CDU) for direct liquid cooling.
- Liquid-to-Liquid Heat Transfer: At this point, the primary and secondary loops converge at the CDU. The CDU facilitates the transfer of heat from the secondary loop, which circulates coolant to the IT equipment, back to the primary loop. The primary and secondary fluids never come into direct contact or mix, ensuring a closed system and maintaining system integrity.
- The Technology Loop: The CDU pumps a cold dielectric (non-conductive) fluid through distribution systems and rack manifolds, or into an immersion tank. As the fluid flows over heat-generating components like GPU processors, it absorbs the heat. The now-heated dielectric fluid is then returned to the CDU to be cooled and the heat is exchanged to the primary loop.

Case Study: A Cooling Solution for an Indonesian Financial Company
As a real-world example, an Indonesian financial company handling millions of transactions daily needed scalable and non-disruptive solutions for their powerful network. This network processes a massive volume of transactions and handles thousands of transactions per second at its peak. The huge power usage of their servers also presented a critical cooling challenge.
With the assistance of Climanusa, they implemented Liquid Immersion Cooling (LIC) technology. This involved submerging their servers in a dielectric synthetic oil that is non-conductive. The results were highly beneficial:
- It eliminated corrosion and jitter common to air-cooled technology.
- It prolonged machine lifespans.
- It was suitable for heat loads higher than contemporary technology (20kW+ per rack).
- It drove up the mean time between failures.
- It used the same standard servers as those in air-cooled racks, without the need for hardware changes.
