RheoPad
An Ultra-Slim Passive Dual-Mode/Two-Phase
Direct Liquid Cooling (DLC) Pad for Mobile Devices
RheoPad represents an advanced two-phase direct liquid cooling (DLC) solution that uses capillary action within a porous structure to manage high-density heat, often utilized in high-performance compute (HPC) electronics and AI servers.
Key Components and Mechanisms:
- Porous heat sink body: Serves as the primary structure, containing pores that absorb and hold a working fluid (liquid or gas).
- Pasting elements (Sheet-like Colloids): Polymer-based elements that fixedly attach the porous heat sink directly to the electronic device (e.g., CPU/GPU).
- Vaporization chamber (Gap): The thickness of the pasting element acts as a narrow gap or vapor chamber, where the liquid absorbs heat and turns into vapor.
Two-Phase Direct Liquid Cooling Mechanism: The liquid in the pores turns into vapor, absorbing a high amount of latent heat. This vaporized fluid then escapes or condenses, removing the heat from the heat sink. This method provides superior cooling efficiency, often outperforming single-phase air or liquid cooling with high compute performance while maintaining low thermal resistance for high-power workloads.

Two-Phase Direct Liquid Cooling Technology
for AI Data Centers
Direct liquid cooling (DLC) is an advanced thermal management approach where coolant is brought in close contact with heat-generating components such as CPUs, GPUs, and accelerators. Instead of relying solely on air, liquid absorbs and transports heat far more efficiently, enabling precise temperature control even under sustained, intensive AI workloads. This is critical for training large models and running complex inference pipelines, where power density and heat output are significantly higher than in traditional IT environments.
By improving thermal efficiency, DLC reduces the need for energy-intensive air conditioning and allows higher rack densities without compromising reliability. Lower operating temperatures can extend hardware lifespan, reduce thermal throttling, and support more predictable performance at scale. In many deployments, direct liquid cooling also contributes to lower overall energy consumption and better Power Usage Effectiveness (PUE), supporting both cost optimization and sustainability goals. As AI data centers continue to grow in scale and complexity, direct liquid cooling is emerging as a modern, future-ready cooling solution for high-density computing environments.
