7 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 dc/dc power modules are characterized in heated wind tunnels that simulate the thermal environments encountered in most electronics equipment. the following figures show the wind tunnel characterization setup. the power module is mounted on primarion test board and is horizontally positioned within the wind tunnel. airflow airflow figure 14: wind tunnel test setup thermal de-rating the module?s maximum hot spot temperature is +113c. 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. figure 15: temperature measurement location the allowed maximum hot spot temperature is defined at 113 j
