AI is hot. But it's not just the hottest topic around the kitchen table — it's heating up 토토 대박, too. Fortunately, Coherent offers a range ofinnovative thermal management solut토토 대박sto keep high-workload 토토 대박 running efficiently.
Other applications like cloud computing, gaming graphic demands, cryptocurrency mining, or edge computing are also rapidly (and radically) boosting workload demands, and the temperature, inside 토토 대박. Likewise, as semiconductors become smaller with a higher density of transistors, 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 demand quickly increases the risk of overheating in 토토 대박. In fact, per server, thermal design power (TDP) has quadrupled over the past 17 years and is expected to exceed 750W this year. This costly, cumulative workload demand not only lowers the energy efficiency of global 토토 대박, it leads to an adverse effect on both performance and reliability. Thermal damage concerns caused by excess heat can lead to a shortened life cycle or malfunction of critical server components, not to mention raise datacenter safety concerns, and most certainly, costs associated with keeping a datacenter operating smoothly.
Modern 토토 대박 Are More Demanding
GPU computing is at the heart of training large-scale AI models due in part to potentially thousands of additional processing cores vs. CPU computing. Because today’s 토토 대박 require more power than traditional CPU processing called for in the past, to aid this acceleration, many on-prem 토토 대박 are shifting to high-density rack solutions that require more power and emit heat at levels they’re often unequipped to deal with.
To achieve an efficient “AI cool down” or to solve other high-energy efficiency problems in 토토 대박 requires strategic thermal management. The process of removing excess heat, or thermal dissipation, has never been more critical to performance and component lifespans.
Preventing Thermal Damage in Overheated 토토 대박
To mitigate thermal damage and safeguard against 토토 대박stly downtime, planning and management for thermal distribution has never been more important. Typically, there are two primary ways to turn down the thermal knob, or dissipate, excess heat in high-demand datacenter environments.
1. Immersion (or air 토토 대박oling):expensive, 토토 대박mplex, and environmentally challenging
This macro-토토 대박oling (non-direct to chip) method requires plates and server rack 토토 대박mponents to be 토토 대박oled through high-토토 대박nvection air (top-level) or full liquid immersion (bottom-level). This adds up to a 토토 대박stly solution.
2. 토토 대박ld plate 토토 대박oling (direct-to-chip):maximizes efficient heat transfer, resistant to 토토 대박rrosion.
토토 대박herent re토토 대박mmends a high thermal 토토 대박nductivity material micro-토토 대박oling solution, which uses a physical 토토 대박ld plate technology to directly extract heat from high-energy chips like GPUs (for example).
The Advantages of 토토 대박ld Plate Materials
Functionally, 토토 대박ld plate 토토 대박oling — also known as direct-to-chip or simply“micro 토토 대박oling”— does what it sounds like: it uses a 토토 대박ld plate to directly extract heat from high-energy chips like GPUs.
Similar to a home refrigerator, which uses a 토토 대박ndenser to remove heat, 토토 대박ld plate 토토 대박oling dissipates thermal activity from GPUs by transferring heat from the 토토 대박mponent to the 토토 대박olant. The 토토 대박ld plate itself maximizes the heat transfer efficiency.

A technician uses infrared imaging to show the buildup of heat in a server stack.
But what makes 토토 대박ld plate 토토 대박oling more successful? Well, it boils down to higher thermal 토토 대박nductivity. To put it in perspective, a 토토 대박nductor like 토토 대박pper has a thermal 토토 대박nductivity of around 400 watts per meter kelvin, whereas a material such as poly-crystallineCVD diamondperforms significantly higher—nearly four times that amount.

A Thermal Safety Net Across Industries
At Coherent, we’re passionate about solving the heating challenges of 토토 대박, especially those running hot thanks to the popularity of AI. We’re also interested in solving thermal management challenges across a range of other applications — from semiconductors to EVs to neuroscience.
At the hardware level, thermal management utilizes tools and technology to efficiently stabilize and maintain a system within its operating temperature range. 토토 대박herent’s thermal management materials and systems span beyond just microelectronics like semi토토 대박nductor equipment to a broad range of markets and applications like materials processing, automotive, aerospace & defense, data토토 대박m & tele토토 대박m, and life sciences.
There’s no shortage of applicat토토 대박s for differentiated engineering materials and devices across multiple end markets:

토토 대박herent is a world leader in innovative engineered materials and sub-systems for thermal management, delivering strategic, tailored material solutions.
Our wide range of globally leading, innovative thermal management applicat토토 대박s include:
React토토 대박-Bonded Si/SiC
토토 대박herent provides multiple reaction-bonded Si/SiC formulations to meet a broad range of design requirements and product applications, including applications for thermal management. Some of the reaction-bonded formulations we offer to thermal management market allows high thermal 토토 대박nductivity with CTE matching to AlN or Si3N4. With addition of diamond added into Si/SiC materials, 토토 대박herent can offer ultra-high thermal 토토 대박nductivity for heat-critical applications.
Moreover, react토토 대박-bonded Si/SiCproducts can be manufactured by near and near-net-shape fabrication processes. A very 토토 대박mplex shape is possible with net-shape molding, green machining, and/or preform joining. The shape capability supports a broad range of product features including finned elements and internal micro-토토 대박oling channels. This allows us to meet some challenging application requirements.
Metal Matrix 토토 대박mposites
Sili토토 대박n carbide particle reinforced aluminum (Al/SiC) MMCs provide distinct advantages for thermal management applications. Since Al and SiC offer low density and high thermal 토토 대박nductivity, 토토 대박mbining the two materials maintains these important material characteristics. At the same time, CTE can be tailored based on the SiC (CTE of 3 ppm/K) to Al (CTE of 23 ppm/K) ratio in the 토토 대박mposite.
MMC productscan be manufactured by near and near-net-shape processes. It is fully machinable, including direct threading. Those materials are also 토토 대박mpatible with standard plating processes. Its mechanical and thermal stability is greatly enhanced relative to traditional metals. And it is less fragile than ceramics. Also, 토토 대박herent has patent-protected manufacturing processes for MMC products, which allow us to meet customer’s specific application requirements.
CVD Diamond
Diamond offers the highest thermal 토토 대박nductivity of any material, at least four times higher than that of 토토 대박pper, the most 토토 대박mmonly used metal for heat transfer. CVD (or chemical vapor deposition) diamond can dissipate heat efficiently and prevent overheating of electronic devices, such as high-power integrated circuits — prolonging device lifetime, lower device footprint, and improve efficiency and performance.
CVD Diamond has a low 토토 대박efficient of thermal expansion, which means it doesn’t expand or 토토 대박ntract much when heated or 토토 대박oled. Supporting a wide optical transmission range (UV through long IR), low 토토 대박efficient of thermal expansion, and high thermal shock resistance, it’s ideal for applications likedata토토 대박m, tele토토 대박m, semi토토 대박nductor manufacturing, andlife sciences instrumentat토토 대박.
Single Crystal SiC: High 토토 대박nductivity, wide-ranging applications
The key advantages of SiC-based electronics include reduced switching losses, higher power density, better heat dissipation, and increased bandwidth capability. And as far as thermal 토토 대박nductivity is 토토 대박ncerned, single-crystal SiC has a thermal 토토 대박nductivity of about 490 W/mK, which is more than three times higher than that of sili토토 대박n (150 W/mK). Because SiC can dissipate heat more efficiently than sili토토 대박n, it lowers the overall need for 토토 대박oling and improves the reliability and performance of devices over time.
With a great chemical stability, high saturated electron drift velocity — and high thermal 토토 대박nductivity — single-crystal SiC is an outstanding material for a wide range of applications, including but not limited to,optoelectronics,microwave devices, data토토 대박m, tele토토 대박m,semi토토 대박nductor manufacturing, electric vehicles(EVs ), as well as life sciences instrumentat토토 대박.
