ds_fl75l07_02162012 3 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 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 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 exceeds the maximum module temperature, reliability of the unit may be affected. note: wind tunnel test setup figure dimensions are in millimeters and (inches) 10 (0.4?) module a ir flow 50.8 ( 2.0? ) facing pwb pwb a ir velocit y a nd ambient temperature measured below the module figure 4: wind tunnel test setup thermal curves figure 5: temperature measurement location the allowed maximum hot spot temperature is defined at 115 j fl75l07 a (standard) output current vs. ambient temperature and air velocity @ vin = 48v (either orientation) 0 1 2 3 4 5 6 7 8 25 35 45 55 65 75 85 ambient temperature ( j ) output current (a) 300lfm natural convectio 200lfm 100lfm figure 6: output current vs. ambient temperature and air velocity @ vin = 48v (either orientation)
