Single Side Curved Flange Large Flow Horizontal Fin Hydraulic Brazed Aluminium Heat Exchanger

This square horizontal fin aluminum hydraulic heat exchanger is mass-produced for medium and large excavators, stationary engineering machinery, pile drivers, and concrete production equipment hydraulic cooling systems. Each cooler features a single left-side 90° bent flange pipe joint with a flat square flange surface for bolted pipeline connection, plus full-edge reserved mounting holes on the top and bottom frame for secure fixed installation.

High-density horizontal louver turbulent fins are integrated through vacuum brazing with internal oil passages, utilizing forced air cooling to rapidly dissipate heat from high-pressure hydraulic oil during long-duration stable construction operations. The uniform standard size design facilitates mass OEM matching for engineering equipment manufacturers, while flange caliber, bending radius, and core thickness support personalized non-standard modifications based on specific equipment heat dissipation requirements.

• Left Side 90° Curved Flange Integrated Interface: Large-area flange sealing surface with strong pressure resistance; bent pipeline avoids rigid extrusion with vehicle frame, effectively reducing pipeline fatigue cracking caused by long-term equipment vibration.
• Full Perimeter Multi-Point Mount Hole Frame: Top and bottom edges feature evenly distributed fixing holes for flexible horizontal or vertical installation, adapting to diverse engine compartment layouts of various construction machinery.
• High-Density Horizontal Louver Turbulent Fin Array: Layered interleaved fin structure breaks air laminar flow, maintaining stable heat exchange efficiency under continuous medium-high pressure hydraulic circulation.
• Integral Thickened Welded Header Box: Reduced internal welding seams improve overall structural rigidity, resisting long-term jolting vibration at construction sites and preventing oil leakage.
• Uniform Standard Square Core Body: Unified external dimension specifications suitable for batch procurement and inventory management by engineering machinery OEM factories and maintenance dealers.

• Material Advantage: Thickened flange and bent pipe structure provides strong pressure and impact resistance, preventing flange deformation and oil leakage under high hydraulic pressure and gravel impact.
• Process Advantage: Integral vacuum brazing core minimizes internal leakage points; each product undergoes independent high-pressure oil tightness testing, significantly reducing after-sales maintenance rates for engineering machinery hydraulic overheating.
• Layout Advantage: Standard square frame with full-edge mounting holes eliminates the need for vehicle bracket modifications during replacement, enabling direct interchangeability for multiple construction machinery models.
• Quality Control: Each cooler completes full oil channel pressure detection; flange flatness, bending angle, and frame flatness are calibrated before delivery, ensuring batch uniform size and matching consistency.
• Customization Advantage: Supports adjustments to flange size, bending angle, core width, and thickness according to drawing requirements; factory mass direct supply with complete specifications and formal invoices, suitable for engineering machinery OEM batch supporting and large maintenance station bulk purchases.
