AUDIOWELL’s Three Innovative Thermal Management Solutions Shine at Sensor Converge 2026

On May 5, 2026, Sensor Converge 2026 – North America’s largest event for electronic design engineers – concluded successfully at the Santa Clara Convention Center in California, USA. At this premier global technology event for sensors and intelligent systems, AUDIOWELL made a stunning appearance with its system-level thermal management solutions for AI computing power and embodied intelligence. Centered around three core innovative products – piezoelectric fans, micro-jet liquid pumps, and secondaryside coolant flow monitoring solutions – AUDIOWELL showcased its deep expertise in smart sensing and precision actuation technologies to a global industry audience. On-site technical explanations and application demonstrations attracted large crowds of attendees, sparking enthusiastic exchanges.

Piezoelectric Fan: An Ultra-Lightweight Thermal Solution Custom-Designed for Embodied Intelligent Robots

The piezoelectric fan (MUAF) is a revolutionary product developed by AUDIOWELL to address the thermal management needs of compact electronic devices. Abandoning traditional fan bearing structures, it uses highfrequency vibration of piezoelectric ceramics to generate a directed jet of airflow, achieving excellent heat dissipation while operating with extremely low power consumption and low noise.

Unlike conventional air-cooling systems that rely on highspeed rotating bearings, the piezoelectric fan operates on a piezoelectric drive principle. The inverse piezoelectric effect of the piezoelectric ceramic produces highfrequency, tiny deformations, which drive air to form a directed high-speed jet. This technical approach fundamentally eliminates bearing friction – there are no mechanical friction parts and no electromagnetic interference – greatly extending operating life while achieving silent operation. With its outstanding heat dissipation efficiency and ultrathin form factor, the piezoelectric fan shows strong application potential in highly integrated thermal management scenarios such as highdensity electronic devices, highcomputingpower chips, and robot joint motors.

Its thin, lightweight design and ultralow power consumption make it an ideal choice for thermal management of humanoid robot joints – helping robots effectively reduce the risk of overheatinginduced shutdowns in joint motors and ensuring longterm stable operation.

Micro Liquid Pump: Ultra-Thin, Zero-Noise Actuator Reshaping Robot Cooling Circuit Design

The micro liquid pump represents a breakthrough for AUDIOWELL in the field of micro-actuators. With an ultra-small footprint of just 7 mm × 7 mm × 1.4 mm, this product achieves precise control of liquid drive. Its thin profile allows it to be integrated directly into the compact modules of downstream devices, offering new degrees of freedom for designing fine-grained cooling circuits in humanoid robots.

As a core power unit for high-performance liquid cooling circulation systems, the micro liquid pump not only features a tiny volume but also delivers zero noise and no electromagnetic interference – making it an ideal “imperceptible drive” actuation component, particularly suited for precision robotics where demanding performance requirements apply.

With embodied intelligence placing ever-higher demands on heat dissipation efficiency, compact structure, and low-noise operation, the micro liquid pump is expected to play a key role in server cold-plate liquid cooling, local heat dissipation inside robot joints, and precision temperature control systems for miniaturized medical devices.

Secondary-Side Coolant Flow Monitoring Solution: Strong Support for AI Server Liquid Cooling

In AI server liquid cooling systems, precise flow monitoring is a critical link for achieving accurate flow and temperature control and ensuring safe system operation. Traditional industrial-grade flow sensors typically use a main-loop monitoring mode, which cannot accurately reflect branch-loop cooling conditions and struggles to meet the growing demands of high-computing-power scenarios.

The secondary-side coolant flow monitoring solution showcased by AUDIOWELL is another innovation achieved by the company leveraging years of accumulated expertise in ultrasonic flow measurement technology and continuous optimization. Based on dual technology routes – ultrasonic sensing and vortex sensing – the product maintains highaccuracy sensing even under gasliquid mixed conditions, achieving measurement accuracy of up to ±3%.

This solution effectively replaces the main-loop monitoring mode of traditional industrial-grade flow sensors with a “main loop + branch loop” dual monitoring architecture. It provides realtime dynamic feedback on temperature and flow variations at each cold plate and heat exchanger node. By implementing precise temperature and flow control through a powerful sensing network, the product ensures stable operation of data center servers under highpower conditions, effectively reduces PUE, improves overall system reliability, and delivers an efficient, intelligent thermal management experience to industry customers.
