ABSTRACT:
A self-contained, wall-mountable cooling and filtering unit for hydraulic drive fluid featuring a coiled heat transfer pipe in a coil chamber which surrounds a drum-type filter cartridge, the hot fluid flowing through the coil chamber in the axial direction, before traversing the filter cartridge in a radial inward direction and exiting from the device. The heat transfer pipe is a finned pipe with an integral helical fin having is originally radial fin wall bent away at four folding lines in a rectangle, to form aligned fold segments in four longitudinal surface planes. The fold segments support superposed pipe turns in the heat transfer coil while positioning the latter against the walls of the coil chamber.
