Copper-Nickel Shell And Tube Oil Cooler For Boat Engine And Ship Power Plant
Copper-nickel shell and tube oil cooler is a premium cooling solution tailored for boat engines and ship power plants. Featuring excellent seawater corrosion resistance and high thermal conductivity, it reliably cools lubricating oil for marine power systems, maintains stable oil performance, and ensures long-term safe operation of vessels and on-board power units.
Why Choose Copper-Nickel Material for Marine Oil Coolers
Marine equipment operates in harsh environments with persistent seawater, salt fog, humidity and vibration. Ordinary carbon steel or regular steel tubes are prone to rust, corrosion and fouling after long-term contact with cooling seawater.
Copper-nickel alloy (Cu/Ni 90/10 or 70/30) stands out as the ideal marine-grade material:
Outstanding resistance against seawater corrosion, marine organism adhesion and salt erosion
Superior thermal conductivity for fast and efficient heat transfer
Good mechanical strength and vibration resistance to adapt to engine room conditions
Low scaling tendency, reducing maintenance frequency and extending service life
Working Principle
This shell and tube oil cooler is installed in series within the lube oil circulation circuit of boat engines and ship power plants.
Hot lubricating oil carrying excess heat from running engines flows through the shell side. Seawater or fresh cooling water circulates inside copper-nickel tubes. Heat transfers through the tube wall to lower oil temperature steadily.
Cooled lube oil retains proper viscosity and lubricating ability, protecting bearings, crankshafts and other key moving parts from overheating damage.
