1. Overview

Fan accessories are essential components in thermal management systems, designed to optimize cooling efficiency, protect equipment, and extend operational lifespan. These accessories include controllers, filters, mounting brackets, and fan guards, which work synergistically with cooling fans in electronic, industrial, and HVAC systems. With increasing power density in modern devices, proper thermal management has become critical to prevent overheating and ensure reliable performance.
