Description

Technical Field

[0001] The utility model relates to the technical field of cooling equipment, in particular to a finned oil cooler guide vane. Background Technique

[0002] The oil cooler is an important component in the engine cooling and lubrication system. Its main function is to dissipate heat from the engine lubricating oil, keep the oil temperature within a suitable range, and ensure the normal operation of the engine and extend its service life.

[0004] However, the existing guide vanes are usually only applicable to guiding in a relatively small temperature range, and the guiding effect will decrease at other temperatures. Therefore, a guide vane that can automatically adjust the guiding effect according to temperature is needed. Content of the Utility Model

[0021] An embodiment of the utility model provides a finned oil cooler deflector, as Figures 1-3 shown, including a main body 11, a first slot 12, a first slider 13, a first support piece 14, a second support piece 15, a second slot 16, a first rotating shaft 17, a limiting block 18, a torsion spring 19, and a guiding piece 20.

[0022] As Figures 1-2As shown, a plurality of first slots 12 are provided on the inner circular surface of the main body 11. A first slider 13 is slidably connected in the first slot 12. The first slot 12 is filled with inert gas. A first support piece 14 and a second support piece 15 are provided between one end of the first slot 12 close to the outer circular surface of the main body 11 and the first slider 13. A second slot 16 is provided on the first slider 13. A first rotating shaft 17 is rotatably connected in the second slot 16. One end of the first rotating shaft 17 is fixedly connected with a limiting block 18. One end of the limiting block 18 away from the first rotating shaft 17 is fixedly connected with a guiding piece 20.

[0023] A torsion spring 19 is sleeved on the outer circular surface of the first rotating shaft 17. One end of the torsion spring 19 is fixedly connected to one end face of the second slot 16. The other end of the torsion spring 19 is fixedly connected to the surface of the limiting block 18 close to the first rotating shaft 17. An arc surface is provided on the guiding piece 20. The guiding piece 20 is made of a heat-conducting material. The diameter of the limiting block 18 is larger than the diameter of the second slot 16. The diameter of the first rotating shaft 17 is smaller than the diameter of the second slot 16.

[0024] Both the first support piece 14 and the second support piece 15 are made of elastic metal materials. Both the first support piece 14 and the second support piece 15 are arc-shaped and arranged in the first slot 12. The diameter of the first support piece 14 is larger than the diameter of the second support piece 15. It should be noted that the first slots 12 are arranged on the main body 11 at equal radian with the axis of the main body 11 as the axis.

[0025] When guiding the flow during the oil cooling process of this solution, the main body 11 is embedded in the pipeline of the oil cooler. When the oil temperature is relatively high, the air pressure in the first slot 12 increases. The inert gas in the first slot 12 pushes the first slider 13 in the direction away from the first support piece 14. The first slider 13 drives the limiting block 18 and the guiding piece 20 to slide in the direction away from the first support piece 14, so as to guide the flow of the oil. When the oil flows, a weak thrust is generated on the guiding piece 20 to make the guiding piece 20 rotate. The guiding piece 20 compresses the torsion spring 19 through the limiting block 18.

[0026] When the oil temperature decreases, the air pressure in the first slot 12 decreases. The inert gas in the first slot 12 pulls the first slider 13 in the direction close to the first support piece 14. The first slider 13 drives the limiting block 18 and the guiding piece 20 to slide in the direction close to the first support piece 14, thereby weakening the flow guiding effect of the guiding piece 20 on the oil. At this time, the first slider 13 compresses the first support piece 14 and the second support piece 15.

[0027] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
