Problems solved by technology
[0004] Due to the high oil inlet pressure of hydraulic oil and the effect of pulse (sudden change of hydraulic oil pressure in the hydraulic pipeline), it is easy to form eddy current (the phenomenon of fluid rotating motion) at the corner of the square oil diffuser, which will cause impact on the oil diffuser pipeline. Destruction, resulting in broken pipe ends, resulting in oil spillage

The invention discloses a hydraulic oil radiator capable of eliminating medium vortexes, and belongs to the technical field of engineering machinery heat dissipation. The hydraulic oil radiator comprises a box body, an upper oil chamber is formed in the upper end in the box body, a lower oil chamber is formed in the lower end in the box body, and the upper oil chamber communicates with the lower oil chamber through a heat dissipation pipeline; an oil return opening communicating with the upper oil chamber is formed in the upper end of the box body, and an oil inlet communicating with the lower oil chamber is formed in the lower end of the box body; and a bypass connector is formed in the end part of the upper oil chamber and communicates with a main oil return pipeline through a bypass pipeline. By additionally arranging the bypass connector at the corner of the upper oil chamber of the square structure of the radiator box body, part of hydraulic oil is guided to return to a hydraulic oil tank through the bypass pipeline, so that the fluid flow direction of a flow field at the corner of the radiator box body is improved, formation of the vortexes is reduced, the adverse effect of the vortexes on the radiator is improved, the service life of a radiator pipeline is prolonged, the radiator failure rate is reduced, and maintenance and spare part cost is saved.
Description
technical field [0001] The invention relates to the technical field of engineering machinery heat dissipation, in particular to a hydraulic oil radiator for eliminating medium eddy currents. Background technique [0002] The existing oil diffuser basically adopts a square structure, the direction of the hydraulic oil is from the bottom to the top, there is an oil inlet at the lower end, an oil outlet at the upper end, and an oil chamber at the top and bottom. There are various pipes between the oil chambers for heat dissipation, hydraulic pressure The oil enters the lower oil chamber through the pipe joint at the lower end and then reaches the upper oil chamber after heat dissipation through the pipeline, and the oil in the upper oil chamber flows back to the hydraulic oil tank through the oil outlet through the oil return pipeline. [0003] Problems in the above-mentioned prior art are: [0004] Due to the high pressure of the hydraulic oil inlet and the effect of the puls...
