Heat Transfer Without Heat Sinks

Increasing airflow over the module enhances the heat transfer via convection. Figure 24 shows the maximum power that can be dissipated by the module without exceeding the maximum case temperature versus local ambient temperature TA for natural convection through 4 m/s 800 ft./min. .

Note that the natural convection condition was measured at m/s to m/s 10 ft./min. to 20 ft./min. however, systems in which these power modules may be used typically generate natural convection airflow rates of m/s 60 ft./min. due to other heat dissipating components in the system.
