Sea water heat exchangers
The main purpose of sea water exchanger is to evacuate the heat produced by the submarine propulsion system outside the hull.
The principle consists in transferring calories from the fresh water cooling loop to sea water from the outside of the ship.
With almost a century of experience and know-how, DCNS provides a range of exchangers adapted to the needs of the different client Navies, for conventional as well as nuclear propelled submarines.
DCNS’ sea water heat exchangers accomodate every specific operational requirement for a submarine, that is :
- corrosion and fouling resistance
- compactnedness and ship integration
- resistance to maximum operating depth, shocks and environmental conditions
- thermal exchange performance by limiting pressure drop
- acoustic discretion
More than 170 heat exchangers for 10 client Navies in the past 50 years:
Brazil, Chile, France, India, Malaysia, Pakistan, Portugal, South Africa, Spain, United Kingdom
