Abstract (en)

[origin: WO2008147062A1] The present invention relates to a hydraulic-operating oil cooling apparatus for cooling hydraulic-operating oil used in various hydraulic machines using hydraulic pressure, and more particularly, to an assembly type hydraulic-operating oil cooling apparatus for a hydraulic machine, which is very convenient in maintenance and repair because a body of the oil cooling apparatus is constructed of several units, and is very excellent in cooling efficiency because cooling water flows through the inside of a heat exchange pipe of the hydraulic-operating oil cooling apparatus as well as the inside of the units.
