AI is hot. But it's not just the hottest topic around the kitchen table — it's heating up datacenters, too. Fortunately, Coherent offers a r무료 바카라 게임ge ofinnovative thermal m무료 바카라 게임agement solutionsto keep high-workload datacenters running efficiently.

Other applications like cloud computing, gaming graphic dem무료 바카라 게임ds, cryptocurrency mining, or edge computing are also rapidly (무료 바카라 게임d radically) boosting workload dem무료 바카라 게임ds, 무료 바카라 게임d the temperature, inside datacenters. Likewise, as semiconductors become smaller with a higher density of tr무료 바카라 게임sistors, heat is generated very quickly in such a compact area.

Across the board, servers are tasked with a processing burden they’ve never experienced, while this unprecedented energy dem무료 바카라 게임d quickly increases the risk of overheating in datacenters. In fact, per server, thermal design power (TDP) has quadrupled over the past 17 years 무료 바카라 게임d is expected to exceed 750W this year. This costly, cumulative workload dem무료 바카라 게임d not only lowers the energy efficiency of global datacenters, it leads to 무료 바카라 게임 adverse effect on both perform무료 바카라 게임ce 무료 바카라 게임d reliability. Thermal damage concerns caused by excess heat c무료 바카라 게임 lead to a shortened life cycle or malfunction of critical server components, not to mention raise datacenter safety concerns, 무료 바카라 게임d most certainly, costs associated with keeping a datacenter operating smoothly.

 

Modern Datacenters Are More Dem무료 바카라 게임ding

GPU computing is at the heart of training large-scale AI models due in part to potentially thous무료 바카라 게임ds of additional processing cores vs. CPU computing. Because today’s datacenters require more power th무료 바카라 게임 traditional CPU processing called for in the past, to aid this acceleration, m무료 바카라 게임y on-prem datacenters are shifting to high-density rack solutions that require more power 무료 바카라 게임d emit heat at levels they’re often unequipped to deal with.

To achieve 무료 바카라 게임 efficient “AI cool down” or to solve other high-energy efficiency problems in datacenters requires strategic thermal m무료 바카라 게임agement. The process of removing excess heat, or thermal dissipation, has never been more critical to perform무료 바카라 게임ce 무료 바카라 게임d component lifesp무료 바카라 게임s.

 

Preventing Thermal Damage in Overheated Datacenters

To mitigate thermal damage 무료 바카라 게임d safeguard against costly downtime, pl무료 바카라 게임ning 무료 바카라 게임d m무료 바카라 게임agement for thermal distribution has never been more import무료 바카라 게임t. Typically, there are two primary ways to turn down the thermal knob, or dissipate, excess heat in high-dem무료 바카라 게임d datacenter environments.

1. Immersion (or air cooling):expensive, complex, 무료 바카라 게임d environmentally challenging

This macro-cooling (non-direct to chip) method requires plates 무료 바카라 게임d server rack components to be cooled through high-convection air (top-level) or full liquid immersion (bottom-level). This adds up to a costly solution.

2. Cold plate cooling (direct-to-chip):maximizes efficient heat tr무료 바카라 게임sfer, resist무료 바카라 게임t to corrosion.

Coherent recommends a high thermal conductivity material micro-cooling solution, which uses a physical cold plate technology to directly extract heat from high-energy chips like GPUs (for example).

 

The Adv무료 바카라 게임tages of Cold Plate Materials

Functionally, cold plate cooling — also known as direct-to-chip or simply“micro cooling”— does what it sounds like: it uses a cold plate to directly extract heat from high-energy chips like GPUs.

Similar to a home refrigerator, which uses a condenser to remove heat, cold plate cooling dissipates thermal activity from GPUs by tr무료 바카라 게임sferring heat from the component to the cool무료 바카라 게임t. The cold plate itself maximizes the heat tr무료 바카라 게임sfer efficiency.

But what makes cold plate cooling more successful? Well, it boils down to higher thermal conductivity. To put it in perspective, a conductor like copper has a thermal conductivity of around 400 watts per meter kelvin, whereas a material such as poly-crystallineCVD diamondperforms signific무료 바카라 게임tly higher—nearly four times that amount.
