Core Technical Specifications
1. Structural & Material Parameters
Structure: Shell-and-tube finned heat exchanger, expand tube process tightly bonds copper fins & heat transfer tubes for high heat exchange efficiency
Heat transfer tube material: High-purity copper tube; fin material: copper (304 stainless steel optional for corrosive water/seawater customization)
Shell material: Carbon steel with anti-rust coating, stainless steel shell available on request
Flow channel design: Large-diameter oil ports to reduce flow resistance and pressure drop
Detachable end cover design for easy internal dirt cleaning & maintenance
2. Pressure & Temperature Ratings
Max working pressure (oil side): 16 bar
Max working pressure (water side): 10 bar
Allowable oil medium temperature: ≤120°C
Allowable cooling water temperature: 5–60°C
Applicable oil kinematic viscosity: 12–320 mm²/s (heavy high-viscosity lubricant customizable)
Cooling water requirement: Low impurity content; seawater, heavily polluted water supported via customized anti-corrosion structure
3. Heat Exchange & Size Range
Single unit heat exchange area range: 1.3 m² ~ dozens of square meters (multiple models DWBE-408 / DWBE-412 / DWBE-414 / DWBE-418 etc.)
Connection ports: G1, G1-1/2 standard thread flanges; SAE flanges optional
Compact layout, small footprint with large heat dissipation capacity compared to traditional tubular coolers
4. Core Product Advantages
High heat transfer efficiency due to fin-enhanced heat exchange surface
Low oil flow resistance, small pressure loss for hydraulic & lube circuits
Easy disassembly for regular descaling and sludge cleaning
Strong adaptability to dirty cooling water and seawater after customized anti-corrosion treatment
Complete series specifications, full supporting pipe fittings & accessories
