[0044] The heat dissipation pipe 600 is provided with a plurality of heat dissipation pipes 600, and the plurality of heat dissipation pipes 600 are uniformly arranged on the distribution pipe 500.

[0045] Specifically, the heat dissipation pipe 600 can be arranged according to actual use requirements, for example, four heat dissipation pipes 600 are arranged, and the first heat dissipation fins 700 are arranged on the outer walls of the four heat dissipation pipes 600 to dissipate heat of the lubricating oil.

[0046] The second heat dissipation fins 116 are arranged on the outer wall of the oil storage cavity 900 and are used for heat dissipation of the oil storage cavity 900.

[0048] Further, the filter screen is arranged at the end of the oil outlet pipe 112 and is used for filtering the lubricating oil.

[0049] The working principle of the utility model is as follows: in use, first, the lubricating oil in the plunger pump 100 is pumped out through the oil inlet pipe 300 connected with the plunger pump 100 (for example, an oil pump is connected on the oil inlet pipe 300, and the lubricating oil in the plunger pump 100 is pumped out through the oil pump), then the lubricating oil is discharged into different heat dissipation pipes 600 through the oil distribution pipe 500, the lubricating oil exchanges heat with the first heat dissipation fins 700 in the heat dissipation pipes 600, and the cooling fan 800 is used for discharging air to the inside of the shell 200, the flowing air carries the heat on the first heat dissipation fins 700 out, and the heat dissipation of the lubricating oil is completed.
