FAQs
What are the advantages of a comb-type heat sink over other types?
Comb-type heat sinks use parallel fins, resulting in a larger heat dissipation area and lower airflow resistance, making them suitable for directional airflow applications. Compared to pin-fin heat sinks, they offer higher heat dissipation efficiency for the same volume, and compared to flat-plate heat sinks, they offer better natural convection.
How do I choose the right material?
Aluminum alloy heat sink(such as 6061/6063): Highly cost-effective, suitable for low- to medium-power applications (such as consumer electronics and LED lighting).
Red copper heat sink(C1100): Optimal thermal conductivity, suitable for high-power chips (such as CPUs, GPUs, and lasers), but at a higher cost.
Aluminum silicon carbide (AlSiC): Matches the thermal expansion coefficient of the chip and is suitable for high-frequency semiconductor packaging.
Titanium alloy: Corrosion-resistant and high-temperature resistant, suitable for aerospace and special environments.
Is a fan required?
Natural heat dissipation: Suitable for applications with heat dissipation less than 10W/cm² (such as routers and LED lighting).
