Spiral Heat Exchanger

Product Overview

Spiral heat exchanger is a compact, high-efficiency heat transfer device with a unique spiral flow channel structure. It is fabricated by rolling two metal plates into a spiral shape, forming two independent sealed flow passages for two fluids. The two media flow in opposite directions inside the spiral channels, achieving full counter-current heat exchange.

Featuring high heat transfer efficiency, anti-fouling performance and small footprint, this equipment is widely used for heating, cooling, condensation and heat recovery. It can be made of carbon steel, stainless steel, titanium and other materials, and is suitable for viscous, easy-to-scale and corrosive media in various industrial fields.

Key Features & Advantages

✅ Superior Heat Transfer EfficiencyFull counter-flow design plus turbulent flow state greatly improves heat exchange coefficient, heat transfer effect is far better than traditional heat exchangers.

✅ Excellent Anti-Fouling PerformanceContinuous spiral flow avoids dead zones; fluid scours the channel wall constantly, effectively reducing dirt accumulation and scaling.

✅ Compact Structure & Space-SavingSmall overall size and light weight, saves installation space and reduces foundation investment.

✅ Strong Corrosion & Pressure ResistanceIntegrated plate structure with reliable welding quality, adaptable to corrosive media and medium pressure working conditions.

✅ Easy Cleaning & MaintenanceTwo-end open structure allows convenient internal flushing and inspection, low long-term maintenance cost.

✅ Wide Application RangeWorks well for liquid-liquid, gas-liquid heat exchange, especially ideal for high viscosity, particulate and easy-crystallization media.

Working Principle

Two metal plates are rolled to form concentric spiral channels, which divide the equipment into two independent flow spaces.

One fluid enters from the outer spiral channel and flows inward along the spiral path.

The other fluid flows outward from the central channel in the opposite direction, forming complete counter-current heat transfer.

During the flow, fluids keep strong turbulence, heat is fully transferred through the metal plate wall.

The special channel structure prevents medium deposition, ensuring long-term stable operation.
