19 Transmitter Cooling Description
The Affinity® LBD-200C-N1 transmitter incorporates a combination of forced ambient air-cooling
and cabinet air conditioning systems. In the ambient system, air enters through the front of each
chassis and exits the rear. Amplifiers use folded-fin heatsink technology for increased cooling
efficiency. The Upconverter chassis uses a similar cooling arrangement with low volume fans for
the lower associated heat dissipation. Accompanying the forced air-cooling systems is the
enclosure air conditioning system sized according to the heat load expected by the transmitter
and ancillary equipment.
