Figure 1-4 Recommended v30 cooling fan locations – free-space cooling
When using a tight-fitting fan shroud designed for side cooling, the cooling fans can be positioned within
5–25 mm (0.20–1.0") of the heatsink fins as long as the same gap is maintained on either side.
Rear cooling
A fan shroud designed for rear cooling can be used to minimize the length of the laser installation
as shown in Figure 1-5. The shroud should enclose the full length of the laser and cooling fan and
must fit snugly against the laser’s heatsink fins. Use a fan rated for at least 8.5 m3/min (300 CFM) at
a static air pressure of 23.9 mm H2O (0.94 in H2O) and position it approximately 150 mm (6.0")
from the rear of the laser

Guidelines for rear cooling
• Design the cooling shroud so that it encloses the full length of both the laser and the cooling fan.
• Fit the shroud snugly against the laser’s heatsink fins so air is ducted between the fins and not
around them.
•
For proper heat removal, open the shroud at the front to direct air flow through the laser.
•
Use a cooling fan rated for at least 8.5 m
