THERMAL CONSIDERATIONS
Thermal management is an important part of the system
design. To ensure proper, reliable operation, sufficient
cooling of the power module is needed over the entire
temperature range of the module. Convection cooling is
usually the dominant mode of heat transfer.
Hence, the choice of equipment to characterize the
thermal performance of the power module is a wind
tunnel.
Thermal Testing Setup
Delta’s filter modules are characterized in heated
vertical wind tunnels that simulate the thermal
environments
equipment. This type of equipment commonly uses
vertically mounted circuit cards in cabinet racks in which
the power modules are mounted.
The
characterization setup. The filter module is mounted on
a test PWB and is vertically positioned within the wind
tunnel. The space between the neighboring PWB and
the top of the power module is 6.35mm (0.25”).
Thermal Derating
Heat can be removed by increasing airflow over the
module. Figure 4 shows maximum output is a function of
ambient temperature and airflow rate. To enhance
system reliability, the power module should always be
operated below the maximum operating temperature. If
the
temperature, reliability of the unit may be affected.
