FAQs
What are the advantages of a sunflower-shaped heat sink compared to a standard fin heat sink?
The radial structure provides a larger heat dissipation area within the same volume, making it particularly suitable for applications where space is limited but high heat dissipation is required.
Does it require a fan?
It depends on the power consumption—for ≤50W, passive cooling is acceptable; for >50W, a fan is recommended (we offer integrated solutions).
Can it be used in humid outdoor environments?
We recommend nickel-plated or anodized versions, which offer IP54 protection.
