Section 1: SYSTEM OVERVIEW
1.6 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 thermostatic mixing valve 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.
