The invention provides a hydraulic oil cooling device which is characterized in that a hydraulic oil heat exchanger in a case communicates with compressors, condensers with fans, and liquid storage devices through two pipelines respectively, and then expansion valves communicate with the hydraulic oil heat exchanger to form two refrigerant circulating pipelines; the hydraulic oil heat exchanger is provided with two hydraulic oil input pipes; the two hydraulic oil input pipes are respectively connected with oil pumps and then are combined to form an input port; an air cooling cooler is additionally arranged at the rear end of the oil pump of one hydraulic oil input pipe; the hydraulic oil heat exchanger is additionally provided with two hydraulic oil output pipes; and the two hydraulic oil output pipes are combined to form an output port. With the adoption of the scheme, when the hydraulic oil cooling device is in use, through heat exchange between a circuiting liquid-state refrigerant and hydraulic oil at cer
