Figure 99. Power Consumption v. Thermal Resistance
The thermal resistance of a heatsink is determined by the heat
dissipation surface area, the material and shape of the
heatsink, and the airflow volume across the heatsink. In
general, the larger the surface area the lower the thermal
resistance.
The required thermal resistance of a heatsink (q_SA) can be
calculated using the following example:
If:
T_C = 70°C
T_A = 45°C
P_MAX = 19.95 W at 350 MHz (Standard-power AMD-K6-2E/350AFR)
Then:
q_CA ˆ _ÍÌË^T---_P-^C---_M--–--_A---^T-_X---^A--_ÝÜÛ = ₁----₉₂----_.5---₉-^•---^C5----_W-- = 1.25 (•C ‰ W)
