The utility model discloses an engineering machinery manifold type hydraulic oil cooler with good heat dissipation performance, which comprises two groups of manifold bundles, each group of manifold bundles has a plurality of chambers extending along the left-right axial length direction and arranged in parallel along the front-back horizontal direction inside, two adjacent chambers are connected through a bypass hole on the shared side wall, the two ends of the chamber are sealed, a refrigerant joint is fixed on the manifold bundle, the two groups of manifold bundles are connected through a plurality of rows of flat tube groups arranged longitudinally, each row of flat tube groups is vertically fixed between two corresponding chambers of the two groups of manifold bundles along the left-right axial length direction, and two adjacent flat tubes in each row of flat tube groups are fixed and connected together through fins. The number of flat tubes and the total cross-sectional area of the flat tubes are effectively increased, the total contact area between the heat exchange medium flowing in the flat tubes and the external air is significantly increased, the heat exchange effect is enhanced, and the heat dissipation performance is excellent. The overall structure is compact and reasonable, has small space occupation, is light and portable, and is economical and practical.
