How to Design Your Heat Sink
When choosing the area of the heat sink, one needs to comprehensively consider factors such as heat dissipation power, material properties, environmental conditions and design constraints. Here is a guide for selecting the area of the heat sink.
Simplified Calculation Formula
For natural convection only:
A ≈ Q / (h · ΔT)
A
heat sink area
Q
Total heat to be dissipated (W)
h
Convective heat transfer coefficient
natural convection: 5–25 W/m²·K
forced air cooling: up to 100 W/m²·K
ΔT
Temperature difference between the heat sink surface and ambient (K)
This area is for a smooth surface requirement. In actual design, the fin efficiency needs to be taken into account.
If you are not sure about the type of heat sink you need to design, Precisionn has professional engineers who can precisely match the required area of the heat sink through systematic calculation and testing. This way, they can ensure that the heat sink meets your needs and avoids overuse of materials or insufficient heat dissipation.
Key Design Considerations
- Match the heat sink material to your specific application requirements
- Consider both natural and forced convection options based on your environment
- Account for fin efficiency in your final area calculations
What did our customers say?
"Our production line used to shut down at least twice a month due to overheating issues. After switching to Precionn’s custom heat sinks, the problem disappeared entirely. The team designed a perfect solution for our limited-space equipment, and delivery was incredibly fast. We’ve saved both time and money, and performance has never been more stable."
"We needed a lightweight yet high-performance cooling solution for an aerospace electronics module. Precionn delivered exactly what we asked for — ISO-certified, precisely engineered, and tested for thermal efficiency. Their expertise in material selection and design optimization really shows. Highly recommended for any critical application."
"Our telecom equipment runs 24/7, and temperature fluctuations used to cause serious instability. Precionn’s custom heat sinks eliminated those risks completely. The product quality is outstanding, and their support team guided us from design consultation to final installation. It’s a rare pleasure to work with a supplier so committed to long-term reliability."
