THERMAL CONSIDERATION

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 DC/DC power modules are characterized in

heated vertical wind tunnels that simulate the thermal

environments encountered in most electronics

equipment. This type of equipment commonly uses

vertically mounted circuit cards in cabinet racks in

which the power modules are mounted.

The following figure shows the wind tunnel

characterization setup. The power 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 constantly kept at

6.35mm (0.25’’).

Thermal Derating

Heat can be removed by increasing airflow over the

module. To enhance system reliability, the power

module should always be operated below the

maximum operating temperature. If the temperature

exceeds the maximum module temperature, reliability

of the unit may be affected.
