In which industries are these ultra-miniature fans, with a diameter of 15mm and a thickness of 4mm (15×15×4mm), primarily used?

I. Consumer Electronics – Smart Wearables and Mobile Devices

Applications: Smart glasses (AR/VR), head-mounted displays, high-performance smartwatches, micro-projectors.

Reason: As companies like Meta and Apple drive the widespread adoption of AR/VR devices, the internal space of these glasses/headsets is extremely limited, but the chips and micro-displays generate heat. A 4mm thickness allows for perfect integration into the temples or a slim body, solving the problem of localized hotspots and ensuring comfort and safety during extended wear.
