SYNRAD OEM v40 Operator’s Manual Version 4
Connecting
SYNRAD recommends side-mounted cooling fans for Firestar v40 lasers but a rear-mounted, single-fan
cooling scheme is also feasible. Figure 1-6 illustrates the rear-cooling concept. Please review the guide-
lines below to ensure that your implementation provides enough airflow to prevent damage to the laser.
The cooling fan must supply at least 300 CFM in order to keep laser and RF heat sink temperatures below
45 °C (113 °F). Note that rear-cooled v40 lasers may experience some performance degradation when
compared to the typical side-mounted cooling configuration. Because of the heat generated by Firestar’s
integrated RF circuitry, establishing significant airflow evenly over the entire surface area of the combined
laser/RF chassis is vitally important to the performance and longevity of the laser.

Rear-mounted cooling
Guidelines for rear cooling
■
The cooling shroud must be designed so that it encloses the full length of both the laser and the
cooling fan.
■
The shroud must fit snugly against the laser’s cooling fins so that cooling air is ducted between the
fins and not around them.
■
To allow proper heat dissipation, the shroud must be open at the front to allow cooling air to flow
away from the laser.
■
Allow 3–4" (76–102 mm) of clearance between the front of the cooling fan and the rear of the laser.
■
To provide proper airflow, the cooling fan should have a diameter of approximately 4.5–5" (114–127
mm) and must supply an airflow of at least 300 CFM distributed evenly over the length and width of
the laser’s cooling fins.
The customer-supplied fan shroud must be designed
so that it encloses both the OEM laser and cooling fan.
