IDTechEx Asks if Single-Phase Cooling is More Favorable than Two-Phase Cooling in Data Centers
BOSTON, July 19, 2023 /PRNewswire/ — With the continuous increase in the thermal design power (TDP) of chips, traditional air-cooling methods are struggling to meet the cooling requirements of modern hyperscale data centers. As a result, liquid cooling has emerged as a promising solution due to the high specific heat capacity of liquids.
Liquid cooling can be categorized into two main types: single-phase liquid cooling and two-phase liquid cooling. The distinction between these two lies in whether a phase change occurs during the cooling process. Two-phase cooling, while offering higher cooling capacity, also presents several challenges, such as higher costs and regulatory concerns, according to IDTechEx’s analysis.
Two-phase coolants are commonly used in both immersion cooling, where the entire electronic component is submerged in the coolant, and direct-to-chip cooling, where the coolant is brought in direct contact with the chip.
Single and Two-Phase Cold Plate
In single-phase cold plate cooling, a coolant such as water glycol is used, which is circulated inside the cold plate by coolant distribution units (CDUs). The coolant absorbs heat through convection as it passes over the heat sources (e.g., GPUs). On the other hand, two-phase cold plates or evaporators utilize dielectric refrigerants with low boiling temperatures. In two-phase cooling, heat absorption primarily occurs through the latent heat during the phase change of the refrigerant. Unlike single-phase cooling, two-phase cold plates do not rely on pumps and CDUs for circulation but instead use temperature-controlled self-regulation, resulting in easier maintenance due to the absence of moving components.
Additionally, most two-phase coolants are non-corrosive, allowing for a wider range of material selection for rack manifold and cold plate housing and reducing maintenance requirements. However, it is important to note that some two-phase refrigerants contain organic fluoro components, which raises concerns about their global warming potential and environmental impact. The discontinuation of certain polyfluoroalkyl substances (PFAS) manufacturing by companies like 3M by the end of 2025 will have implications for both two-phase cold plates and two-phase immersion cooling.
In the case of single-phase cold plates, the pressure drop is a critical parameter. The CDU pumps the coolant through manifolds and quick disconnects, and an uneven pressure drop can lead to varying flow rates among different cold plates, resulting in uneven cooling. While the flow rate can be theoretically controlled manually to achieve infinite cooling capacity, in practice, the coolant is typically pumped at a temperature close to its boiling point, necessitating the use of around 20% of the maximum pumping speed to prevent cavitation. This imposes practical barriers to adoption, as achieving high cooling capacities would require a significant volume of water, such as 2.5 liters per minute for a cold plate with a 1000W cooling capacity. More details about the single and two-phase cold plates, along with the material considerations for CDUs and manifolds, can be found in IDTechEx’s latest research report, “Thermal Management for Data Centers 2023-2043“.
Single and Two-Phase Immersion
Immersion cooling is known for its high cooling efficiency, offering a low partial power use effectiveness (pPUE) of 1.01, which is the lowest among all data center cooling approaches. However, due to PFAS regulations and environmental concerns, there is a trend toward transitioning to single-phase immersion cooling and using PFAS-free and low fluorine coolants. These transitions, although promising, come with high costs and operational complexities. Additionally, ensuring compatibility between the liquid coolant and servers remains an ongoing challenge.
Nevertheless, there have been notable collaborations between immersion cooling vendors and server suppliers. Major companies have initiated pilot projects, indicating a growing interest and investment in immersion cooling technology. IDTechEx forecasts that the annual revenue of immersion cooling hardware will exceed US$200 million, presenting a significant opportunity for stakeholders in the industry.

Markets Show Resilience Ahead of End-of-Year Options Expirations: Bybit x Block Scholes Crypto Derivatives Report
DUBAI, UAE, Dec. 26, 2024 /PRNewswire/ — Bybit, the world’s second-largest cryptocurrency exchange by trading volume, released the latest Crypto Derivatives Analytics Report in collaboration with Block Scholes, highlighting the muted market volatility despite major options expirations on Friday. BTC and ETH’s realized volatility has increased, but short-term options haven’t adjusted to this change. This indicates that while spot prices are fluctuating, the options market is not fully reacting to these shifts, although BTC and ETH volumes have displayed slightly different patterns.
With more than $525 million in BTC and ETH options contracts expiring on Dec 27, 2024’s end-of-year options expiration looks set to be one of the biggest yet, yet expectations for volatility have remained subdued. The report highlights an unusual inversion in ETH’s volatility structure, but BTC has not mirrored the reaction. Additionally, a change in funding rates—sometimes turning negative as spot prices drop—signals a new market phase. Notably, BTC’s volatility structure has been less responsive to changes in spot prices, whereas ETH’s short-term options are exhibiting more noticeable fluctuations.
Key Findings:
BTC Options Expirations:
In the past month, BTC’s realized volatility has been higher than implied volatility on three occasions, each time reaching a relatively calm equilibrium. Open interest in BTC options remains high, contributing to potential increased volatility as we near the end of the year. Around $360 million worth of BTC options (both puts and calls) are set to expire soon, which can affect price movement.
ETH Options: Calls Dominate
Despite a mid-week inversion, ETH’s volatility term structure has flattened, maintaining levels similar to those seen over the past month. In the final week of 2024, calls overwhelmed puts in open interest in ETH options, although market movements and trading activities are more on the put side.
