AI Computing Is Creating New Challenges for Thermal Management
Artificial intelligence is entering a new era of high-performance computing. With the development of advanced AI platforms such as NVIDIA Blackwell and future-generation architectures, chip power consumption continues to increase rapidly.
Current AI GPU platforms are already reaching 1000W–1200W power levels, while future platforms are expected to approach the 2000W range.
As computing performance increases, thermal management has become one of the biggest challenges for next-generation AI infrastructure.
Higher power density creates:
- Increased heat generation
- More concentrated hotspots
- Greater cooling system requirements
- Higher reliability demands
Traditional cooling technologies are approaching their physical limits. To support future AI servers, the industry needs a more efficient and scalable thermal solution.
Suzhou Shengrongyuan Electronic Technology Co., Ltd. believes the future of AI cooling requires innovative thermal architectures rather than simply improving existing technologies.
Why Traditional 3D Vapor Chambers Are Approaching the 1500W Limit
For years, 3D Vapor Chambers (3DVC) have been widely used for high-performance thermal management because of their excellent heat spreading capability.
However, when power consumption continues beyond approximately 1500W, traditional vapor chamber structures face increasing challenges.
Limitations of Conventional 3D Vapor Chamber Technology
Traditional 3DVC relies on internal capillary structures to achieve liquid return during the phase-change cooling process.
Under extremely high thermal loads:
- Internal flow resistance increases
- Vapor-liquid circulation becomes more difficult
- Pressure drop becomes more significant
- Dry-out risks increase
These limitations can reduce cooling efficiency and may lead to thermal throttling under extreme operating conditions.
For future AI servers requiring 2kW-class thermal management, conventional cooling solutions face significant scalability challenges.
MLHP: Aerospace-Inspired Cooling Technology for AI Infrastructure
What Is MLHP?
MLHP (Multi-Loop Heat Pipe) is an advanced passive two-phase cooling technology developed by Suzhou Shengrongyuan Electronic Technology Co., Ltd.
Unlike traditional heat pipes and vapor chambers, MLHP utilizes a proprietary multi-loop structure that enables multiple heat transport paths to operate cooperatively.
This innovative design improves heat transfer performance under high-power and high-heat-flux conditions.
From Aerospace Thermal Control to AI Server Cooling
The technology foundation of MLHP comes from aerospace thermal management research.
Shengrongyuan’s core technical team, originating from the Chinese Academy of Sciences (CAS), has spent more than a decade researching thermal control technologies for demanding aerospace applications.
Through years of development, this gravity-independent thermal technology has been transformed into a commercial solution designed for modern AI infrastructure.
Today, MLHP provides a new approach for:
- AI servers
- High-performance computing systems
- Advanced data center cooling applications
