This square aluminum hydraulic radiator is specifically designed for medium tonnage excavators, road rollers, and compact engineering vehicles. It features an asymmetric multi-joint layout with three vertically distributed threaded oil ports on the left side for oil inlet, return, and auxiliary pressure detection, plus a single large-caliber main oil port on the right side.

Six evenly distributed mounting lugs (3 upper, 3 lower) provide stable overall locking installation. Dense horizontal louver turbulent fins are integrated through vacuum brazing with internal multi-channel oil passages, enabling main circulation and auxiliary test pipeline integration in one cooler to effectively control hydraulic oil temperature during long-term mixed load construction operations.

• Left Vertical Triple Multi-Function Ports Design integrates main oil inlet, oil return, and pressure measuring exhaust interfaces, eliminating extra external branch pipelines
• Right Single Large-Caliber Main Oil Outlet features smooth large-flow inner cavity to reduce hydraulic circulation resistance
• Six-Point Uniform Perimeter Mount Lugs provide symmetric upper and lower multi-point stress bearing to disperse vibration impact
• High-Density Horizontal Interleaved Louver Fin Matrix expands heat exchange contact area for continuous stable heat dissipation
• Integral Stamped Thickened Side Plate Frame reduces split welding seams and enhances overall anti-vibration performance

• Material Advantage: Thickened integrated side plate and port base provide strong pressure resistance and prevent deformation under long-term high hydraulic pressure
• Process Advantage: Integral vacuum brazing forming reduces internal oil leakage risks with multi-channel high-pressure tightness testing
• Layout Advantage: Six-point surrounding fixed structure avoids local stress concentration and reduces pipeline accessories
• Quality Control: Every cooler undergoes full oil channel pressure inspection with calibration of mounting lug hole position and port thread concentricity
• Customization Advantage: Supports adjustment of port quantity, thread standard, core width and thickness according to equipment drawings
