Cooling
The cooling circuit is a closed loop that supplies a glycol/water (50% distilled water and 50% glycol) mix
to:
•
The motor drive box to remove heat from the drive electronics
•
The brake manifold to remove heat from the brake hydraulic circuit
•
The gyro enclosure water jackets to remove heat from the flywheel bearings
The heated fluid then passes through a thermostat before bypassing or flowing through a heat
exchanger that has sea water on the cold side. The circuit also contains a coolant reservoir for coolant
expansion and to make filling easy. The reservoir contains a 7 psi (0.5 bar) pressure cap.
