1.2.6.3 Heat Exchanger
The heat exchanger, which is usually installed outside, has 2 fans. The fans are
enabled whenever the pump module is activated, but temperature sensors determine
when the fans will actually start. The first one turns on when the coolant
temperature reaches 32
o
C with the second one turning on at 38
o
C.
1.2.6.4 Transmitter Cold Plates
Each PA Module has an attached liquid cooled cold plate which connects to the
cooling system with flexible hoses and quick release connectors. There is also a
separate cold plate mounted inside the transmitter cabinet to which all of the
combiner reject loads are attached. See Figure 1-7.
