Description
Technical Field
[0001] The utility model belongs to the technical field of oil cooler structures, in particular to an air-cooled oil cooler for an all-terrain vehicle. Background Art
[0002] The oil cooler is an indispensable part of the engine lubrication system. Its main function is to ensure that the oil maintains a suitable operating temperature. When the engine is running, the oil temperature will rise. If the temperature is too high, the oil will become thinner, thereby reducing its lubrication effect. This may cause the engine to not work properly, so the role of the oil cooler is particularly critical.
[0003] There are two main types of oil coolers: water-cooled and air-cooled. Water-cooled coolers use cooling water to adjust the oil temperature. When the oil temperature is high, the cooling water absorbs the heat of the oil, thereby lowering its temperature. Air-cooled coolers, on the other hand, rely on the wind generated by the car when it is running to dissipate heat, and are suitable for high-speed vehicles such as racing cars.
[0004] The SSV (Side By Side Vehicle) is a type of all-terrain vehicle used for competition. It often uses an air-cooled oil cooler. The engine of this type of vehicle will run at a high speed of more than 7000r / min for a long time during driving. For this high-power engine, since it generates a lot of heat, after it runs for a long time, the existing air-cooled oil cooler cannot fully meet the function of cooling the oil.

[0006] To achieve the above-mentioned purpose and other related purposes, the utility model provides an air-cooled oil cooler for an all-terrain vehicle, which is provided with a first oil inlet and an oil outlet, and includes a cylinder assembly installed on the outside of the vehicle body, wherein the interior of the cylinder assembly is provided with a second baffle, a first bowl cover with the bowl mouth facing upward, a second bowl cover with the bowl mouth facing downward, a third baffle and a fourth baffle in sequence from top to bottom; a scissor-shaped opening is provided inwardly on the outer wall of the second baffle; a bowl cover oil leakage hole is provided at the bottom of the side wall of the first bowl cover, and a gap is left between the bowl edge of the second bowl cover and the inner wall of the cylinder assembly; baffle oil leakage holes are provided on both the third baffle and the fourth baffle, and are staggered with each other.
[0007] Optionally, a first partition and a first conduit are also installed inside the cylinder assembly, and the first conduit passes through the first partition, the second partition, the first bowl cover, the second bowl cover, the third partition and the fourth partition from top to bottom in sequence; the first oil inlet is located above the first partition, and an opening is provided on the first partition, and a plurality of conduit oil leakage holes with different apertures are provided on the first conduit.
[0008] Optionally, a second conduit is further installed inside the cylinder assembly, and the second conduit passes through the first baffle and the second baffle; the upper end surface of the second conduit is lower than the upper end surface of the first conduit.
[0009] Optionally, the second conduit is arranged in a curved manner.
[0010] Optionally, a plurality of duct partitions are provided inside the first duct, and the duct partitions are arranged obliquely from top to bottom; the upper side of the duct partition is inserted into an insertion groove opened on the first duct, and a gap is left between the lower side of the duct partition and the inner wall of the first duct; the insertion grooves of two adjacent duct partitions are arranged at 180° intervals along the circumference of the first duct.
[0011] Optionally, it also includes an upper fixing seat and a lower fixing seat installed on the outside of the vehicle body; the upper and lower ends of the cylinder assembly are respectively fixedly mounted on the upper fixing seat and the lower fixing seat; the first oil inlet is arranged on the upper fixing seat, and the oil outlet is arranged on the lower fixing seat.
[0012] Optionally, an oil filter is also installed on the lower fixing seat.
[0013] Optionally, a second oil inlet is also provided on the upper fixing seat.
[0014] Optionally, a transparent oil level tube is installed outside the cylinder assembly, and the upper and lower ends of the transparent oil level tube are respectively connected to the upper and lower ends of the cylinder assembly.
[0015] Optionally, the barrel assembly, the first partition, the second partition, the first bowl cover, the second bowl cover, the third partition and the fourth partition are all made of aluminum alloy.
[0016] As described above, the air-cooled oil cooler for an all-terrain vehicle of the utility model has at least the following beneficial effects:
[0017] 1. The air-cooled oil cooler of the all-terrain vehicle comprises a cylinder assembly installed on the outside of the vehicle body, a second baffle, a first bowl cover with a bowl mouth upward, a second bowl cover with a bowl mouth downward, a third baffle and a fourth baffle installed in sequence from top to bottom inside the cylinder assembly, a scissor mouth is provided inwardly on the outer wall of the second baffle, a bowl cover oil leakage hole is provided at the bottom of the side wall of the first bowl cover, a gap is left between the bowl edge of the second bowl cover and the inner wall of the cylinder assembly, and baffle oil leakage holes are provided on both the third baffle and the fourth baffle and are staggered with each other.

Compared with the oil cooler in the prior art, the air-cooled oil cooler of the all-terrain vehicle significantly improves the cooling effect of the oil and meets the function of cooling the oil when the engine is running at a high speed for a long time during driving.
[0018] 2. The air-cooled oil cooler of the all-terrain vehicle passes through the first baffle, the second baffle, the first bowl cover, the second bowl cover, the third baffle and the fourth baffle from top to bottom in sequence through the first conduit. The first oil inlet is located above the first baffle. The first baffle is provided with an opening. The first conduit is provided with a plurality of conduit oil leakage holes of different apertures. When a small amount of oil enters the oil cooler, the high-temperature oil directly leaks from the opening to the second baffle, and then flows downward in sequence; when too much oil flows in, the oil can flow downward from the opening and the end of the first conduit, thereby diverting the oil and ensuring that the high-temperature oil can fully flow inside the cylinder assembly to achieve a better cooling effect.
[0019] 3. The air-cooled oil cooler of the all-terrain vehicle further diverts the large amount of oil flowing into the cylinder assembly through the design of the second conduit, which further ensures the full flow of high-temperature oil inside the cylinder assembly and improves the cooling effect of the oil cooler.
[0020] 4. The air-cooled oil cooler of this all-terrain vehicle is designed with an oil filter installed on the lower fixing seat, so that the user can remove the oil filter from outside the vehicle for cleaning or replacement. Compared with the design of installing the oil filter inside the vehicle body, the oil filter is installed outside the vehicle body together with the air-cooled oil cooler, which improves the maintainability of the all-terrain vehicle.
[0021] 5. The air-cooled oil cooler of this all-terrain vehicle uses a transparent oil level tube design. Compared with the design of a built-in oil dipstick in the engine, the user can quickly check the oil level outside the vehicle, which is more convenient.
[0022] 6. The air-cooled oil cooler of this all-terrain vehicle is designed with aluminum alloy through the cylinder assembly, the first partition, the second partition, the first bowl cover, the second bowl cover, the third partition and the fourth partition. Compared with iron alloy, it is lighter and more corrosion-resistant; compared with materials such as engineering plastics, it has better heat dissipation effect. BRIEF DESCRIPTION OF THE DRAWINGS
