What Affects Cooling Component Design?
- Heat load and operating temperature range
- Available space, fin height and airflow direction
- Mounting points and contact-surface flatness
- Fan, thermal pad, heat pipe or interface requirements
- Weight, surface treatment and appearance requirements
From Design to Finished Heat Sink
1. Review Thermal RequirementsConfirm heat source, contact area, airflow, space and mounting conditions.
2. Select the Manufacturing RouteEvaluate extrusion, machining, cutting and secondary operations.
3. Produce a SampleCheck dimensions, interfaces, finish and installation fit.
4. Inspect the ComponentVerify critical dimensions, surfaces, holes and appearance.
5. Repeat ProductionApply approved requirements to future batches.
