How to Specify Bulk Heat Sinks
Selecting the appropriate heat sink for mass production is a balance of thermal performance, cost, and mechanical integration. Submit datasheets or part numbers of your target semiconductors for expert help in profile selection.
- Confirm mounting requirements: hole pitch, clip style, pad/insulator spec
- State expected dissipation (W) and ambient temperature for thermal sizing
- Include post-processing needs: anodising, cutting, or pre-assembly, if required
- Consider lead time for large/recurring draws-stock rotation possible for scheduled orders
Thermal Design Example
For a local inverter assembly dissipating 20 W to keep the case below 70 degreesC, and a maximum ambient of 35 degreesC, calculate needed thermal resistance:
SA = (Tcase-max - Tambient) / Power = (70 - 35) / 20 = 1.75 degreesC/W
Select an extruded profile with SA <= 1.5 degreesC/W (add safety margin) and check stock dimensions to fit your board/enclosure.
