Is there any equipment to cool the hydraulic system?

The main function of hydraulic system in electromechanical equipment is to transmit pressure by using the principle of "the internal pressure of liquid is equal everywhere", so that the pressure can be greatly increased by using a larger cross section. For example, liquid oil with a certain internal pressure generated by an oil pump is delivered to a hydraulic actuator, such as a hydraulic cylinder, through a hydraulic pipeline. The high-pressure oil acts on the piston, so that the pressure at both ends of the piston is unbalanced and the piston moves to do work. The high-pressure oil can also act on the circumferentially arranged blades to drive the blade shaft to rotate. This is the oil motor. Hydraulic system is a device to transmit pressure, and hydraulic oil is the carrier of pressure transmission. The liquid with a certain pressure acts on a certain area to generate a force, which drives the parts to move.
