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.
