Description
Customized Design Multitube Cooler for Hydroturbine
Multi-tube coolers are shell-and-tube heat exchangers that serve as critical auxiliary equipment for hydro-turbine lubrication systems and hydraulic governor systems. Hot lubricating oil flows through the shell side while cooling water circulates inside the tube bundles, transferring heat from oil to cooling water to maintain optimal temperature levels for thrust bearings, guide bearings, and governor hydraulic oil.
Excessively high oil temperatures can degrade oil quality, accelerate bearing wear, cause hydraulic valve malfunctions, and create operational risks for unit stability.
We provide custom-engineered multi-tube cooler solutions based on customer drawings, heat load requirements, oil and cooling water flow rates, working pressures, installation space constraints, and water medium characteristics.
Main Technical Features
  • Flexible Material Selection: Tube bundles available in copper alloy, stainless steel, or titanium alloy to accommodate cooling water with sediment, scaling, or corrosive ions. Shells feature carbon steel with anti-rust epoxy coating.
  • High Heat-Exchange Efficiency: Optimized baffle-plate layout enhances fluid turbulence, improves heat transfer coefficients, and reduces heat-exchange area requirements.
  • Maintainable Structure: Removable tube-bundle design allows core bundles to be extracted for cleaning scale, sludge, and sediment without cutting main pipelines, significantly reducing maintenance time.
  • Reliable Anti-Leakage Performance: Advanced tube-to-tube-sheet expanding-and-welding composite process. Every cooler undergoes rigorous hydraulic pressure leak testing to prevent water-oil mixing risks.
  • Customized Configuration: Matched connection flanges, working pressures, and overall dimensions according to on-site layouts; single-pass or multi-pass flow structures available.
Application Scope
  • Auxiliary equipment supply for new-built hydropower stations
  • Turbine lubrication and governor-system upgrades and capacity-increase retrofitting
  • Overhaul spare-part replacement for Francis, Kaplan, bulb, and pumped-storage reversible units
  • Medium-to-large hydropower plants, EPC contractors, and power-plant operators worldwide
Our Services
  • Custom design and fabrication according to customer drawings or technical specifications
  • Material and structural optimization for scaling, silt-laden, or corrosive cooling-water conditions
  • Complete factory inspection including hydraulic pressure leak testing, dimensional checks, and appearance inspection
  • Technical support for transportation, on-site installation, commissioning, and maintenance guidance
Please provide your heat-load parameters, drawings, or working-condition requirements. We will deliver targeted technical proposals and quotations tailored to your specific needs.
