6.5.1Heatsink Orientation

Since this solution is based on a unidirectional heatsink, mean airflow direction must be aligned with the direction of the heatsink fins.

6.5.2Extruded Heatsink Profiles

The reference torsional clip heatsink uses an extruded heatsink for cooling the PXH component. Figure 6-7Figure 6-7Figure 6-7 shows the heatsink profile. Appendix A lists a supplier for this extruded heatsink. Other heatsinks with similar dimensions and increased thermal performance may be available. Full mechanical drawing of this heatsink is provided in Appendix B.

6.5.3Mechanical Interface Material

There is no mechanical interface material associated with this reference solution.
