The Type III Through-Type Spiral Plate Heat Exchanger is a high-flow heat transfer solution with straight-through channels and cross-flow design. Engineered for large-volume gas/liquid exchange, it features detachable construction for easy maintenance while handling high-viscosity fluids and fouling-prone media.
Structural Features
Straight-Through Flow Paths
Enables mechanical cleaning access without disassembly (e.g., rodding or jet washing).
Optimized Gap Design
Strategic clearance at condensation ends reduces pressure drop by 25-40% vs. conventional spiral exchangers.
Cross-Flow Configuration
Ideal for large gas volumes (up to 50,000 m³/hr) with minimal resistance.
Asymmetric Channels
Wide flow sections (typical 12:1 ratio) prevent clogging in high-viscosity fluids.
Technical Advantages
Ultra-Low Resistance
Tesla valve-inspired geometry (validated by Jiang et al., 2024) cuts gas-side pressure loss to <150 Pa/m.
Fouling Immunity
Through-type design allows in-place cleaning , reducing downtime by 60%.
Thermal Efficiency
Cross-flow pattern achieves 85-92% heat recovery in gas-liquid applications.
Scalability
Modular construction supports units up to DN2000 diameter for industrial-scale deployment.
Application
Optimized for high-flow, high-fouling scenarios:
- Power Plant Exhaust Gas Recovery : Preheats feedwater using turbine flue gases.
- Petrochemical Processing : Cools viscous crude derivatives or polymer melts.
- HVAC Systems : Manages large ventilation air streams with minimal fan energy.
- Waste Heat Boilers : Handles particulate-laden off-gases from smelting processes.
Technical Team
Since its establishment, Suzhou Ukada Energy Saving Technology Co., Ltd. has maintained a strong technical team. General Lu, who works in the company's research and development center, has focused on the design and manufacturing of spiral plate heat exchangers since 1982. He also once served as the chief engineer of Suhua Machine, during which time he accumulated rich experience in research and development.
General Lu has successfully completed the research, development and manufacturing work of spiral plate heat exchangers for a variety of national key projects. These projects cover important fields including satellites, submarines and nuclear plants. Moreover, he took part in the drafting and formulation of the national energy industry standard for spiral plate heat exchangers, and this standard was officially implemented in 2016. Currently, General Lu holds the position of engineer at Suzhou Ukada.
