A two-phase cooling system for the Jetfoil Visual Augmentation System
Abstract
The two-phase 'thermosiphon' principle is employed by a novel cooling system developed for temperature control of the IR-illumination and camera night Visual Augmentation System (VAS) used by a commercial hydrofoil craft. Performance comparisons are conducted between the two-phase and current, pumped loop VAS cooling systems, after the construction and testing of a full scale thermosiphon device. The new system is found to raise temperatures slightly, but eliminates a significant portion of the current system's operating noise and reduces cooling system weight by 67 percent.
