Corrosion Prevention TRIZ Cases
- Heat Exchanger Sacrificial Fin Corrosion Protection
Controlled Mg and Zn in fins creates potential difference for sacrificial protection, eliminating costly surface treatments.
- Defrostable Heat Exchanger With Flow Blockage
A defrostable heat exchanger moves a blockage upstream to divert liquid flow, enabling continuous cooling while warm gas melts ice buildup.
- Multistage Vacuum Pump Purge Gas Control Module
Sensors feed back flow data to a control module that dynamically adjusts restrictors, eliminating manual valve adjustments and reducing nitrogen waste.
- Tube-side Pulsable Flow Shell-and-Tube Heat Exchanger
A tube-side sequentially pulsable-flow shell-and-tube heat exchanger apparatus varies flow rates within tubes to inhibit agglomeration.
- Plate Heat Exchanger Cleaning via Reverse Gas Flow
Reverse flow cleaning cycles remove impurities from plate heat exchanger channels without disassembly, maintaining steady gas flow during continuous production.
- Zirconium-Modified Aluminum Alloy for Heat Exchanger Corrosion Resistance
Zirconium addition in aluminum alloy suppresses intergranular corrosion propagation while maintaining extrusion rate equal to A1070 alloys.
- Modular Plate Heat Exchanger for OTEC Corrosion and Maintenance
Segmented plate assemblies isolate brazed joints from seawater to reduce corrosion while maintaining high heat transfer efficiency.
- Monolithic Finned Tube With Split Channels For Dual-Phase Heat Transfer
Monolithic fins with split channels manage condensate shedding to resolve interface resistance and enable efficient dual-phase operation.
- Hydraulic Tubing Rust Prevention via Dual-Surface Coating
Dual-surface zinc treatments prevent internal rust contamination in stored hydraulic tubing.
