In order to control the temperature of the hydraulic oil, on the one hand, high-efficiency components are used, and the system is designed reasonably to minimize the power loss of the hydraulic system; on the other hand, measures must be taken to dissipate the heat generated in the system. Generally, the heat dissipation through the oil tank cannot meet the requirements, and a cooler must be provided in the hydraulic system. The working principle of the hydraulic oil cooling machine is: the high-temperature hydraulic oil flows into the heat exchange pipe from the oil inlet pipe, and then the heat exchange pipe is cooled by water cooling or air cooling to obtain cooled hydraulic oil which flows out from the oil outlet pipe.
