Module Derating
Experiment Setup
From the experimental set up shown in figure
31, the derating curves as figure 32 can be
drawn. Note that the PWB ( printed-wiring
board ) and the module must be mounted verti-
cally. The passage has a rectangular cross-
section. The clearance between the facing
PWB and the top of the module is kept 13 mm
(0.5 in.) constantly.
Convection W
Convection Without Heat Sinks
ithout Heat Sinks
Heat transfer can be enhanced by increasing
the airflow over the module. Figure 32 shows
the maximum power that can be dissipated by
the module.
In the test, natural convection airflow was mea-
sured at 0.05 m/s to 0.1 m/s (10 ft./min. to 20
ft./min.). The 0.5 m/s to 4.0 m/s (100 ft./min. to
800 ft./min.) curves are tested with externally
adjustable fans. The appropriate airflow for a
given operating condition can be determined
through figure 32.
Example 1. How to calculate the minimum
airflow required to maintain a desired Tc?
If a AEH20A24N module operates with a 24V
line voltage, a 20 A output current, and a 40 ° C
maximum ambient temperature, What is the
minimum airflow necessary for the operating?
Determine PD ( referenced Fig.30 ) with con-
dition:
Vin = 24 V
lO = 20 A
Get: PD = 15 W
And with TA = 40 °C
Determine airflow ( Fig.32 ):
v = 1.5 m/s (300 ft./min.)
Example 2. How to calculate the maximum
output power of a module in a certain con-
vection and a max. TA?
What is the maximum power output for a
AEH20A24N operating at following conditions:
Vin = 24 V
v = 1.5 m/s (300 ft./min.)
TA = 40 °C
Determine PD ( Fig.32 )
PD = 15W
Determine IO ( Fig.30 ):
IO = 20 A
