FOR CED AIR COOLING

EXAMPLE

This graph may be used as a guide to determine the Thermal resistance of any extruded section with forced

convection.

The thermal resistance of a heatsink is 0.35ºC/W assume the heatsink is placed in a air velocity of 4m/s. Then

0.35ºC/W x 0.3 becomes 0.105ºC/W approx.

Performance figures are shown as an indication of a heatsinks actual performance. It is recommended that the effectiveness of any

heatsink is tested in the specific operating environment in which it will be subjected
