[0011] As an improvement of the hydraulic oil heat dissipation and exhaust filter element of the utility model, the edge of the lower cover extends upward to form an arc-shaped rib, and an oil collecting groove is formed between the arc-shaped rib and the rubber plug fixing sleeve. The oil collecting groove can collect the oil condensed by the filter material, and the oil is cooled in the oil collecting groove. When the oil collecting groove is full of oil, it will overflow and return to the oil tank.

[0012] As an improvement of the hydraulic oil heat dissipation and exhaust filter element of the utility model, the filter material is an activated carbon material. The activated carbon material has the function of adsorbing oil pollution and can effectively realize oil and gas separation.

[0013] The beneficial effect of the utility model is that the utility model can prevent the oil gas from being directly discharged into the atmosphere, thereby reducing pollution.
