ADW Showcases Advanced Thermal Management Solutions for AI and Embodied Intelligence

ADW presented its latest system-level thermal management technologies for AI computing and embodied intelligence applications, highlighting three innovative core solutions: the Microjet Air Fan (MUAF), the Microjet Liquid Pump, and the Secondary-Side Coolant Flow Monitoring Solution.

These technologies demonstrate ADW’s deep expertise in intelligent sensing and precision actuation, providing advanced thermal management solutions for high-density computing systems, robotics, and next-generation intelligent devices.

Microjet Air Fan (MUAF): Ultra-Lightweight Cooling for Embodied Robotics

The Microjet Air Fan (MUAF) is a revolutionary cooling solution developed by ADW for compact and highly integrated electronic systems. Unlike conventional cooling fans that rely on rotating bearing structures, the MUAF utilizes high-frequency vibration generated by piezoelectric ceramics to create directed microjet airflow.

This innovative piezoelectric-driven approach delivers several major advantages:

• No mechanical bearing friction

• No electromagnetic interference

• Extremely low operating noise

• Significantly extended service life
  

  
  

By leveraging the inverse piezoelectric effect, the system produces microscopic high-frequency deformation that drives high-speed directional airflow with exceptional efficiency.

Thanks to its ultra-thin structure, low power consumption, and outstanding cooling capability, the MUAF demonstrates strong application potential in:

• High-density electronic systems

• High-performance AI chips

• Robotic joint motors

• Compact intelligent devices

For humanoid robots in particular, the lightweight design and efficient thermal management capability help reduce the risk of joint motor overheating, ensuring stable long-duration operation and improved system reliability.

Microjet Liquid Pump: Ultra-Thin Silent Actuator for Next-Generation Cooling Systems

The Microjet Liquid Pump represents a major breakthrough in ADW’s micro-actuation technology portfolio. With an ultra-compact size of only 7 mm × 7 mm × 1.4 mm, the pump enables highly precise liquid flow control within extremely space-constrained modules.

Its miniature dimensions provide unprecedented flexibility for advanced cooling pipeline designs in humanoid robots and other compact intelligent systems.

As a core power unit for high-performance liquid cooling systems, the Microjet Liquid Pump offers several key advantages:

• Ultra-thin compact structure

• Zero operating noise

• No electromagnetic interference

• High precision fluid control
  

• 
  

These characteristics make it an ideal “invisible drive” actuator for precision robotic applications where thermal efficiency, compact integration, and silent operation are critical.

As embodied intelligence systems continue demanding higher cooling performance and more compact architectures, the Microjet Liquid Pump is expected to play an important role in:

• Cold plate liquid cooling systems for AI servers

• Localized cooling inside robotic joints

• Precision temperature control systems for miniaturized medical devices
  

Secondary-Side Coolant Flow Monitoring Solution: Intelligent Support for AI Liquid Cooling Systems

Precise coolant flow monitoring is a critical requirement for AI server liquid cooling systems, enabling accurate thermal control and ensuring reliable operation under high-power conditions.

Traditional industrial flow meters typically rely on main-loop monitoring architectures and cannot accurately reflect thermal conditions within branch cooling circuits, limiting their effectiveness in modern high-performance computing environments.

ADW’s Secondary-Side Coolant Flow Monitoring Solution builds upon years of expertise in ultrasonic flow sensing technology. The solution integrates both ultrasonic sensing and vortex flow sensing technologies, maintaining highly accurate monitoring performance even under mixed gas-liquid operating conditions.

Key capabilities include:

• Measurement accuracy up to ±3%

• Real-time dual-channel monitoring of both main and branch cooling circuits

• Dynamic temperature and flow feedback for cold plates and heat exchangers

• Intelligent thermal regulation through advanced sensing networks
  

• 
  

By replacing traditional single-loop monitoring architectures with a “main loop + branch loop” monitoring system, the solution enables precise thermal management for data center servers operating under high computational loads.

This advanced thermal control capability helps:

• Improve system stability

• Reduce PUE (Power Usage Effectiveness)

• Enhance overall cooling reliability

• Optimize energy efficiency in AI infrastructure

Through its integrated sensing and actuation technologies, ADW continues to provide efficient and intelligent thermal management solutions for next-generation AI computing and embodied intelligence systems.
