9.5 Thermal Considerations

  • Design to be as cool as practical
  • Design the product to meet recommended operating conditions when the DMD is operating. Absolute maximum ratings are provided as a guide for short term life testing and not long-term operation
  • Storage Conditions are always applicable the DMD is not operating. This includes times when before and after the DMD is installed
  • Design the cooling to comprehend the full temperature range the DMD will be used. To help meet the DMD temperatures in extreme ambient conditions the speed of the cooling fans could be increased, or the optical power reduced
  • Thermal testing early using a thermal mockup before part designs are finalized and tooling started allows simple changes to be made that can improve thermal performance without impacting schedule or tooling costs.
  • Refine the thermal mockup as the design matures and do additional testing.
  • The DMD data sheet identifies specific thermal test point locations that should be used when doing thermal testing.
  • The T_array specification in the DMD data sheet is the calculated array temperature from the identified thermal test point. A sample calculation is provided in the data sheet.
  • Thermal testing of the DMD should be done in the enclosure of the unit. Thermal testing of a standalone optical module has very different airflow and cooling characteristics which results in very different temperatures than those in the enclosed unit.
