Wide Channel Plate Heat Exchanger BW100A

The wide-channel plate heat exchanger is specially optimized for handling media with high viscosity, containing particles or fibers, as well as fluids prone to scaling. The application limitations of ordinary plate heat exchangers under complex working conditions have been solved through a unique flow channel structure

Characteristics

Wide-spaced flow channel design

The width of the flow channel can reach 2-5 times that of conventional plate heat exchangers, significantly reducing flow resistance and preventing particle or fiber accumulation and blockage. It is suitable for slurries, sludges, syrups, etc., which are high-viscosity or contain impurities.

Enhanced heat transfer technology

Special stamping processes (such as inclined waves, spherical protrusions, etc.) are adopted for the corrugated plates, ensuring a turbulent state even when the flow channel is widened. The heat transfer coefficient can reach 3-5 times that of shell-and-tube heat exchangers.

Anti-scaling and ease of maintenance

The large flow channel reduces the retention area, combined with the detachable plate structure, facilitates mechanical cleaning or chemical cleaning, significantly extending the maintenance period and reducing downtime costs.

Material and seal compatibility

Available in stainless steel, titanium, Hastelloy, etc. The sealing gasket has a wide temperature range (-40℃ to 200℃), suitable for corrosive media or high-temperature conditions.

Product Introduction

Working principle

Fluid flow path:

Two media flow alternately through wide channels (counterflow or parallel flow), and the corrugated plates force the fluid to form turbulence, enhancing heat transfer.

The wide channel design reduces the flow velocity (typically 0.1 - 0.5 m/s), reduces pressure drop, and yet the turbulence can still disrupt the boundary layer, maintaining high thermal efficiency (K value can reach 3000 - 6000 W/m²·K).

Heat transfer mechanism:

Convection dominant: The corrugated plates enhance fluid turbulence, enabling efficient heat exchange even in wide channels.

Applicable media: Can handle fluids with viscosities up to 10,000 cP (such as syrups, sludge) or media containing solid particles (diameter ≤ 15 mm).

Industrial field:

Chemical industry: Polymer reaction substances, high-viscosity oil products for heat exchange.

Food industry: Heating/cooling of fluid containing particles such as juice and chocolate.

Environmental protection: Sludge heat recovery in sewage treatment.

Special conditions:

Solutions containing crystalline particles (such as salt concentration).

Fiber suspensions (such as in the paper industry).
