Integrated Split Dual Core Frame Type Horizontal Brazed Aluminum Heat Exchanger

This integrated frame-mounted dual-layer combined aluminum radiator is a complete cooling assembly designed for medium-sized construction machinery including loaders, road rollers, concrete mixing equipment, and medium excavators. It features an upper large horizontal fin water cooling core combined with a lower small hydraulic oil cooling split dual-core layout, with an integrated expansion water tank pre-installed on top.

The design includes full-side perforated vertical mounting frames on both sides for overall fixed assembly. Horizontal louver turbulence fins are vacuum brazed separately for water and oil channels, enabling dual heat dissipation of engine coolant and hydraulic oil in a single unit. This effectively resolves dual high-temperature faults in both engine and hydraulic systems during extended construction operations.

• Dual-Core Integrated Combined Structure: Upper water radiator and lower hydraulic oil cooler integrated into one unit, simultaneously handling engine water cooling and hydraulic oil cooling while saving equipment cabin space
• Top Built-In Integral Expansion Water Tank: Integrates liquid storage, exhaust, and pressure stabilization functions, eliminating the need for separate external water tank installation
• Bilateral Full Perforated Vertical Mount Frame: Multiple uniform reserved mounting points for efficient overall hoisting fixed installation
• Horizontal Multi-Louver Turbulent Fin Array: Layered heat exchange structure with independent flow channels for water and oil without mutual interference
• Closed Integrated Frame Protection Shell: Wraps the entire core body, protecting against gravel impact on construction sites

• Material Advantage: Integrated thickened outer frame wraps the entire cooling core, providing strong anti-collision performance and reducing fin damage from construction site flying stones
• Process Advantage: Independent vacuum brazing for water and oil dual cores ensures completely separate flow channels without cross leakage, with dual tightness testing before delivery
• Layout Advantage: All-in-one combined design reduces the number of independent cooling parts, significantly shortening OEM assembly time
• Quality Control: Complete dual-channel water and oil pressure tightness testing; frame verticality, expansion tank sealing and mounting hole position calibration before factory delivery
• Customization Advantage: Supports adjustment of upper/lower core size, expansion tank volume and mounting hole spacing as required, with factory direct supply and full range of models
