Heat Exchanger (fig. 1-18).
This system has the heat exchanger located downstream of the flow
limiting venturi large outlet and prior to the condenser.
exchanger has a bleed air flow length of 15.65 in.
make this single-flow, cross-flow, plate-fin type heat exchanger
entirely of an aluminum alloy.
Operation (fig. 1-19).
Bleed air flows from the flow
limiting venturi at a maximum of approximately 200 cfm with
a pressure of 35,F ƒ2,F maximum.
The bleed air flows
through the passageways lined with rectangular fins set in
an offset configuration, much the same as the precooler.
The cooling air flows through the heat exchanger in
passageways lined with fins placed in a wavy configuration.
The heat exchanger uses outside air as the cooling air. A
fan (to be described later) draws the cooling air through
the heat exchanger.
The cooling air flows through the
deswirl vanes to the precooler and out the exhaust exit.
The deswirl vanes remove any turbulence created by the fan.
