AI Technical Summary
Technical Problem
Existing cooling methods for external systems of a vessel hull, such as pistons and shafts, are inefficient and burdensome, requiring additional equipment installation, maintenance, and pose risks like leakage and pollution, especially in seawater-based systems.
Method used
A cooling method that redirects and sprays mechanical parts with water externally, using a water flow chamber and a tube to redirect water flow for cooling, eliminating the need for additional equipment and energy-consuming systems.
Benefits of technology
Achieves efficient cooling of mechanical parts without additional installation, reducing operating temperatures and avoiding overheating, while minimizing maintenance and environmental risks.

Abstract
The invention concerns a cooling system for external mechanical parts (1) of vessel hull, such as stabilization fins, which move hydraulically, pneumatically or electrically. The system uses water flow around the vessel for cooling. A water flow chamber (5), placed externally, directs the water. A tube (6), inserted partially within the chamber (5) with inclination, redirects part of the flow toward the mechanical part (1), spraying it and achieving cooling. The tube (6) can have fixed or variable cross-section for adjusting pressure and spraying surface.
