Robotic Applications

The humanoid and service robotics market is on track to reach more than 600 million humanoid units in service by 2050. As these platforms become more capable, they also run hotter; modern edge-AI processors now dissipate 400-700 W inside the chassis, sitting next to high density 2 kWh+ battery packs, 28 or more structural actuators, and DC-DC converters that absorb the heat of 10 minute fast charge cycles. Without active thermal management, sustained autonomy, motor torque, and AI inference performance all degrade.

The Sunon total thermal solution for robotics brings the same brushless DC motor technology, magnetic levitation bearings, and CAE validated airflow design used in our industrial cooling fans into compact, robot ready form factors. From whisper quiet 12.8 dBA axial fans for human facing service robots to IP68 sealed fans for warehouse AMRs and integrated fan plus vapor chamber modules for AI compute boards, Sunon is a single source partner from chip level cooling to chassis level airflow, all backed by 300+ qualified module designs and in-house thermal simulation.

Robots concentrate heat in distinct compartments, each with its own acoustic, environmental, and thermal load constraints. Sunon’s three product families map directly onto these zones:

• Head & sensor compartment: facial motors, vision processors, and audio systems demand whisper quiet airflow. Super Silent Fan Series (12.8-22.1 dBA) keeps social and service robots imperceptible to people.
• Torso electronics bay: AI compute boards, motor controllers, and on-board power electronics generate the highest heat density. Active Fan Cooler Modules with heatpipe and vapor-chamber options dissipate 20-300 W in tight enclosures.
• Battery pack & quick charge electronics: high density Li-ion packs and DC-DC converters under 10 minute fast charge cycles. Active modules with high static pressure push air through dense battery stacks.
• Hip, knee, and shoulder actuators: servo drivers and BLDC motor controllers embedded in limbs, exposed to constant shock and vibration. Patented AntiVib Motor Structure delivers extended fan reliability under continuous mechanical loading.
• Outdoor, dusty, or washdown chassis exposure: warehouse AMRs, agricultural and food service robots, and outdoor delivery platforms. GF Series IP56 and IP68 sealed fans rated for dust ingress and water immersion.

• Three coordinated product families covering robotics thermal needs from 20 W actuator boards to 300 W AI compute payloads.
• Super silent axial fans as quiet as 12.8 dBA, engineered with patented Ultra silent Sound Engineering for human facing robots.
• IP56 and IP68 dust and waterproof fans for warehouse AMRs, agricultural robots, construction and outdoor service platforms.
• Active fan cooler modules with integrated heatpipe, vapor-chamber, or stamped fin heatsink and with 300+ proven designs ready for fast NPI.
• Patented AntiVib Motor Structure plus MagLev and vapo bearings for low vibration and continuous duty operation.
• Wide input 4.5-13.8 V and 12 V DC operation matched to common robot battery-bus voltages.
• In-house CAE thermal simulation for temperature, velocity, fan flow, blower flow, and motor torque modeling to validate cooling before tooling.
• Global safety approvals: UL, cUL, CE, TÜV, UKCA, CCC, CSA, and ATEX, with IP-rated variants tested to industry standard dust and water ingress protocols.
• Single source from component to system: axial fans, blowers, heatsinks, heatpipes, vapor chambers, and fully integrated active cooling modules with liquid cooling and L2A/L2L module options for next generation robotics platforms.
