Product Description

Double Stage Superimposed Black Sprayed Multi Flange Vertical Brazed Aluminium Heat Exchanger

Double-Stage Superimposed Black Sprayed Multi-Flange Vertical Fin Integrated Cooler
Customized for new energy heavy-duty mining trucks, large electric engineering loaders, and hydrogen fuel cell commercial vehicle integrated thermal management systems.
Product Overview
This two-layer stacked black coated aluminum composite heat exchanger features upper and lower superimposed independent cooling cores with separate square flange interfaces. Each layer includes multi-position integrated lifting and fixing lugs on the top and bottom frame. Dense vertical parallel heat exchange fins are vacuum brazed separately for upper and lower flow channels, forming two completely isolated closed circulation loops for simultaneous heat dissipation of power battery packs, drive motors, hydrogen fuel cell stacks, and high-pressure hydraulic systems.
The surface features high-temperature anti-corrosion black electrostatic spraying, resistant to mine dust, muddy water, and temperature alternating impact. Core size, flange aperture, and mounting lug positions support full drawing customization according to vehicle thermal management requirements.
Core Feature Highlights
  • Double-Layer Superimposed Independent Dual-Circuit Structure - completely separated upper and lower flow channels without medium cross-flow
  • Independent Square Flange Interface For Each Layer - large-area flange sealing surface with high pressure resistance
  • Multi-Position Integrated Lifting & Mount Lugs - top double hanging lugs + bottom integrated support frame
  • High-Density Vertical Low-Wind-Resistance Fin Matrix - large heat exchange area while controlling air resistance loss
  • Full Black High-Temperature Anti-Corrosion Coating - uniform protective film on aluminum surface
