Technical Field

[0001] The utility model relates to the technical field of hydraulic oil cylinders, in particular to a hydraulic oil cylinder with a heat dissipation structure. Background Art

[0002] As we all know, hydraulic cylinder is a hydraulic actuator that converts hydraulic energy into mechanical energy and performs linear reciprocating motion. It has a simple structure and reliable operation. When it is used to achieve reciprocating motion, the deceleration device can be eliminated, and there is no transmission gap, and the movement is smooth. Therefore, it is widely used in the hydraulic systems of various machines.

[0003] When the existing hydraulic cylinder is in use, heat energy will accumulate due to the friction between the hydraulic oil and the parts inside the cylinder body. If the accumulated heat energy is not handled in time, cavitation will occur in the cylinder, which will affect the service life and working efficiency of the cylinder. For this reason, we propose a hydraulic cylinder with a heat dissipation structure.
