Heat Transfer Without Heat Sinks

Increasing airflow over the module enhances the heat transfer via convection. Figures 8 and 10 show 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 3 m/s 600 ft./min. .

Systems in which these power modules may be used typically generate natural convection airflow rates of 60 ft./min. due to other heat-dissipating components in the system. Therefore, the natural convection condition represents airflow rates of up to 60 ft./min. . Use of Figure 8 is shown in the following example.

Example

What is the minimum airflow necessary for a QW030BK operating at VI = 48 V, an output current of A, each and a maximum ambient temperature of 89 °C?

Solution

Given VI = 48 V IO1 = A, IO2 = A TA = 89 °C

Determine PD Use Figure 9 :

PD = W
