ABSTRACT:
A system for operating a hydraulic tool is disclosed in which heated hydraulic fluid being returned to a fluid reservoir from the tool is cooled by a refrigeration system. The heated hydraulic fluid is introduced into the hollow interior of a distributor from which the fluid exits through a plurality of orifices in a planar side in the form of plural sprays directed onto adjacent portions of a coil carrying evaporating refrigerant. The sprays flow over the coil to effect substantial transfer of heat from the hydraulic fluid to the refrigerant, with the cooled hydraulic fluid being stored in the reservoir prior to being pumped to the hydraulic tool as needed.
