What is the metal mesh on the heatsink called?
The metal mesh covering the heatsink is professionally called a "protective mesh" or "dustproof mesh," like a breathable mask for the heatsink. Its main function is to prevent fingers from accidentally touching hot components and to trap hair, paper scraps, and other debris. Interestingly, laptop heatsink mesh has a higher density, reaching 40-60 holes per square centimeter, while desktop heatsink mesh typically only has 20-30 holes.
Difference Between Protective Nets and Dustproof Nets
- Protective Nets: Woven with thicker metal wires, focusing on physical protection; commonly found in high-temperature equipment such as electric heaters.
- Dustproof Nets: Mostly made of fine nylon or metal mesh, primarily for filtration; commonly used in computer cases.
- Composite Nets: Many products now use a double-layer design, with an outer layer for impact protection and an inner layer for dust protection, like putting a "raincoat" on the radiator.
Cleaning and Maintenance Tips
This seemingly simple metal mesh actually requires regular care: Lightly brush off surface dust with a soft brush monthly; disassemble and wash quarterly (water temperature not exceeding 40℃). Special Reminder: Be sure to thoroughly dry the mesh after washing before reinstalling, as a humid environment may cause oxidation spots on the metal mesh. If the mesh surface is deformed by more than 30% of its area, it is recommended to replace it promptly to ensure heat dissipation efficiency.
