[0028] The cooling assembly 25 includes a first spiral tube 251 provided at the top of the inner cavity of the shell 21. The top end of the first spiral tube 251 passes through the shell 21 and is connected to one end of the oil drain pipe 22.

The bottom end of the second spiral tube 253 passes through the shell 21 and is connected to the top of the tee pipe 24. A condensate tank 254 is installed on one side of the shell 21. A condensate pump 255 is installed at the bottom of the inner cavity of the shell 21. The liquid outlet end of the condensate pump 255 is connected to a condensate pipe 256.

The liquid inlet end of the condensate pump 255 passes through the shell 21 and is connected to one side of the condensate tank 254.

[0029] In this embodiment, the hydraulic oil enters the interior of the shell 21 through the connection between the oil drain pipe 22 and the first spiral tube 251. When the hydraulic oil enters the interior of the shell 21, the condensate pump 255 extracts the condensate inside the condensate tank 254 and injects it into the interior of the condenser tube 256. The condensate pump 255 and the condenser tube 256 cooperate to dissipate cold air into the interior of the shell 21. The spiral design of the first spiral tube 251 and the second spiral tube 253 can make the hydraulic oil fully contact with the cold air inside the shell 21, so as to fully reduce the temperature of the hydraulic oil.

[0033] During the oil discharge and oil intake process of the hydraulic cylinder 11 of the present invention, the hydraulic oil enters the interior of the shell 21 through the connection between the oil discharge pipe 22 and the first spiral tube 251. When the hydraulic oil enters the interior of the first spiral tube 251, the first spiral tube 251 injects the hydraulic oil into the interior of the filter box 2521 through the connection with the filter box 2521 to filter the impurities in the hydraulic oil. When the hydraulic oil enters the interior of the shell 21, the condensate pump 255 extracts the condensate inside the condensate tank 254 and injects it into the interior of the condenser pipe 256. The cooperation between the condenser pump 255 and the condenser pipe 256 is used to dissipate cold air into the interior of the shell 21. The spiral design of the first spiral tube 251 and the second spiral tube 253 can make the hydraulic oil fully contact with the cold air inside the shell 21, so as to fully reduce the temperature of the hydraulic oil.
