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

Surface area ~ 0.5 m

(P 200 84 Meccal)

Surface area ~ 0.25 m

(P115 80 Meccal)

: 39 °C

: 47 °C
