Description

Hydraulic oil radiator for eliminating medium eddy

Technical Field

The invention relates to the technical field of engineering machinery heat dissipation, in particular to a hydraulic oil radiator for eliminating medium eddy.

Background

The existing oil radiator basically adopts a square structure, hydraulic oil moves downwards and upwards, an oil inlet is formed in the lower end of the oil radiator, an oil outlet is formed in the upper end of the oil radiator, an upper oil chamber and a lower oil chamber are respectively arranged, pipelines are communicated among the oil chambers and used for radiating heat, the hydraulic oil enters the lower oil chamber through a pipe joint in the lower end of the oil radiator and then reaches the upper oil chamber after being radiated by the pipelines, and oil in the upper oil chamber flows back to a hydraulic oil tank through an oil return pipeline through the oil outlet.

The prior art has the problems that:

due to the large oil inlet pressure and the pulse (sudden change of hydraulic oil pressure in a hydraulic pipeline), vortex (the phenomenon that fluid does rotary motion) is easily formed at the corner of the square oil dispersion, impact damage is caused to the oil dispersion pipeline, and the end of the pipeline is broken to cause oil dispersion and oil leakage.

Disclosure of Invention

In order to solve the technical problem, the invention provides a hydraulic oil radiator for eliminating medium eddy.

The invention is realized by the following technical scheme: a hydraulic oil radiator for eliminating medium eddy comprises a box body, wherein an upper end in the box body is an upper oil chamber, a lower end in the box body is a lower oil chamber, and the upper oil chamber and the lower oil chamber are communicated through a heat dissipation pipeline; an oil return port communicated with the upper oil chamber is formed in the upper end of the box body, and an oil inlet communicated with the lower oil chamber is formed in the lower end of the box body; and a bypass interface is arranged at the end part of the upper oil chamber and communicated to the main oil return pipeline through a bypass pipeline.

It further comprises the following steps: an oil return port on the box body is connected with a main oil return pipeline, and the main oil return pipeline is connected to an oil tank.

The upper oil chamber is square, and the bypass interface is positioned at the corner of the upper oil chamber.

The bypass interfaces are provided with 1 to 4.

Compared with the prior art, the invention has the beneficial effects that: the bypass connector is additionally arranged at the corner of the upper oil chamber of the square structure of the radiator box body, and part of hydraulic oil is guided to return to the hydraulic oil tank through the bypass pipeline, so that the flow direction of fluid in a corner flow field of the radiator box body is improved, the formation of eddy current is reduced, the adverse effect of the eddy current on the radiator is improved, the service life of a radiator pipeline is prolonged, the fault rate of the radiator is reduced, and the maintenance and spare part cost is saved.

Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is further described in detail with reference to the following embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the scope of the invention.

Referring to fig. 1 and 4, the hydraulic oil radiator for eliminating medium eddy comprises a box body, wherein an upper oil chamber 2 is arranged at the upper end inside the box body, a lower oil chamber 5 is arranged at the lower end inside the box body, and the upper oil chamber 2 and the lower oil chamber 5 are communicated through a heat dissipation pipeline 4. The upper end of the box body is provided with an oil return port 3 communicated with the upper oil chamber 2, the oil return port 3 is connected with a main oil return pipeline, and the main oil return pipeline is connected to an oil tank. The lower end of the box body is provided with an oil inlet 6 communicated with the lower oil chamber 5.

The hydraulic oil is collected in the lower oil chamber 5 through the oil inlet 6 and then is shunted to the heat dissipation pipeline 4 for cooling and heat dissipation. The hydraulic oil cooled by the heat dissipation pipeline 4 is collected in the upper oil chamber 2, and the cooled hydraulic oil flows through the main oil return pipeline through the oil return port 3 and returns to the hydraulic oil tank.

Go up grease chamber 2 and be square, go up the tip of grease chamber 2 and seted up bypass interface 1, bypass interface 1 is located grease chamber 2's corner position department. The bypass ports 1 are provided with 1 to 4. The bypass connector 1 is connected to the main oil return pipeline through a bypass pipeline.
