4.4. Thermal simulation
Using a computer, matching heat sink housing forms and
occurring maximum temperatures can be calculated by
means of numerical heat simulation.
Two thermo simulation examples:
T heat sink:
38…41 °C
T heat sink:
46…49 °C
T ambient: 25 °C
T ambient: 25 °C
Surface area ~ 0.5 m 2

Surface area ~ 0.25 m 2
(P115 80 Meccal)
