Hydraulic oil cylinder with cooling function

The hydraulic oil cylinder with the cooling function comprises a cylinder body, a first oil inlet and a second oil inlet are formed in the cylinder body, two installation rings are arranged on the cylinder body in a spaced mode, the installation rings are located between the first oil inlet and the second oil inlet, a plurality of connecting rods are fixed between the installation rings, and the connecting rods are connected with the first oil inlet and the second oil inlet. According to the hydraulic oil cylinder, the problems that in the prior art, heat dissipation is carried out on the hydraulic oil cylinder through a water cooling assembly, but after the temperature of cooling liquid rises, the heat dissipation effect is greatly reduced, and the cooling effect is poor are solved. For some small hydraulic oil cylinders, water tanks and water pumps are installed on the outer sides of the hydraulic oil cylinders, the cost is high, and normal use of the hydraulic oil cylinders can be affected due to the fact
