Wide-Flow-Channel Plate Heat Exchanger
The wide flow channel plate heat exchanger features ultra-wide spacing flow channels engineered for challenging industrial heat transfer conditions. Its core technical innovation adopts an enlarged plate gap of 8–15 mm, paired with an optimized corrugation structure integrated with square grid diversion zones and streamlined guide grooves for uniform fluid distribution.
Custom-built for processing media containing coarse solid particles (up to 10 mm in diameter), long fibers (up to 15 mm in length), and high-viscosity liquids, it effectively resolves the clogging vulnerability of conventional plate heat exchangers and overcomes the low thermal efficiency limitations of shell-and-tube heat exchangers.
This specialized PHE supports flexible flow path configurations, including wide-wide and wide-narrow channel combinations. Its adaptable structural design enables quick parameter adjustments to fit diverse process requirements, making it a versatile solution for industrial heating, cooling, and waste heat recovery applications across multiple sectors.
Key Features
-
Outstanding Anti-Clogging Performance: Designed with coarse corrugations and wide clearances, the corrugated heat transfer zones have no metal contact points, creating fully free fluid flow. Even when handling particle-laden, fiber-containing or highly viscous media, the flow channels remain unobstructed with excellent fluid passing capacity, completely solving the clogging issue of traditional narrow-gap plate heat exchangers.
-
Superior Heat Transfer Efficiency: Equipped with square grid diversion areas and streamlined guide grooves, the plates ensure uniform fluid distribution without dead zones or uneven flow rates. The special corrugation induces strong turbulence at low flow velocity, delivering high waste heat recovery rates and significantly cutting energy consumption.
-
Compact & Flexible Modular Structure: Plates with multiple groove depth specifications are available to form wide-wide or wide-narrow channel combinations flexibly according to fluid properties and process requirements. The compact overall footprint occupies far less floor space than shell-and-tube heat exchangers under identical heat load, simplifying installation and plant layout optimization.
-
Wide Compatibility for Complex Working Conditions: Heat transfer plates can be customized from corrosion-resistant materials including 304, 316, 316L stainless steel, titanium, titanium-palladium alloy and Hastelloy. Sealing gaskets are optional in NBR, EPDM, FKM to match various temperature, pressure and corrosive media, suitable for regular fluids as well as special media with solids, fibers or ultra-high viscosity.
