DETAILED DESCRIPTION

[0020] The technical solutions in the embodiments of the utility model will be clearly and completely described below with reference to the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the utility model.

[0021] Embodiment one:

[0022] Please refer to the drawings of the embodiments of the utility model Figure 1 - the drawings of the embodiments of the utility model Figure 5The utility model provides a high -efficient air -cooled oil cooler, including the shell 1, be equipped with oil liquid channel subassembly 2 in the inside of shell 1, the inside and the outside of shell 1 are equipped with heat dissipation subassembly 3, and the upper and lower bottom surface of shell 1 is all set up and penetrates the limiting hole 7, and oil liquid channel subassembly 2 includes oil cavity 201, and the top of oil cavity 201 is fixedly installed with the oil inlet 202 of setting in the inside of upper end limiting hole 7, and the bottom of oil cavity 201 is fixedly installed with the oil outlet 203 of setting in the inside of lower end limiting hole 7, and the rear side inner wall of oil cavity 201 is fixedly installed with a plurality of groups of first flow guide plate 204 of distribution is equidistant, and the front side inner wall of oil cavity 201 is fixedly installed with a plurality of groups of second flow guide plate 205 of distribution is equidistant, and the left and right sides of shell 1 are fixedly installed with mounting column 4, and the bottom of two mounting column 4 is fixedly installed with stable base 5, and the front side surface of shell 1 is fixedly installed with dust screen 6, and shell 1 is the cuboid structure, and the whole oil cavity 201 is the sealed cavity structure, and the shape of oil cavity 201 is adapted to the inside space of shell 1, and a plurality of groups of first flow guide plate 204 and a plurality of groups of second flow guide plate 205 are regularly and orderly alternately distributed in oil cavity 201.

[0023] The mounting column 4 and the stable base 5 of the bottom of the left and right sides of the shell 1 provide a stable support structure for the cooler, which can effectively reduce the loosening and displacement of the cooler caused by vibration and other factors during operation. The dust screen 6 installed on the front side surface of the shell 1 can effectively prevent dust and impurities from entering the cooler and adhering to the heat dissipation assembly 3, thereby affecting the heat dissipation effect. At the same time, the dust screen 6 is easy to disassemble and clean, reducing the maintenance workload and cost of the cooler and ensuring that the cooler always maintains good heat dissipation performance. The shell 1 adopts a cuboid structure, and the shape of the oil cavity 201 is adapted to the internal space of the shell 1 and forms a sealed cavity structure. This design facilitates the overall manufacturing and installation of the cooler.

[0024] Specifically, the first flow guide plate 204 and the second flow guide plate 205 arranged in the oil cavity 201 are regularly and orderly alternately distributed. When the oil enters the oil cavity 201 from the oil inlet 202, the multiple groups of first flow guide plates 204 and second flow guide plates 205 can guide the oil to form a tortuous and uniform flow path in the oil cavity 201, avoiding the occurrence of flow dead zones or local flow rate unevenness. This greatly increases the contact area and contact time of the oil with the heat dissipation assembly 3, thereby significantly improving the heat exchange efficiency and enabling the oil temperature to be reduced more quickly and effectively.

[0025] Example Two:

[0026] Please refer to the attached Figure 1 - attached Figure 3 and attached Figure 5Furthermore, based on Embodiment 1, the heat dissipation assembly 3 includes a rear cover 301, a first heat dissipation fin 304, a second heat dissipation fin 306, and a heat dissipation pipe 305. The rear cover 301 is fixedly installed at the rear end of the outer shell 1. An air inlet mesh 302 is fixedly installed at the end of the rear cover 301 away from the outer shell 1. A cooling fan 303 is fixedly installed inside the rear cover 301. The heat dissipation pipe 305 is spirally arranged and fixedly installed on the outer surface of the oil cavity 201. The first heat dissipation fin 304 and the second heat dissipation fin 306 are respectively installed on both sides of the heat dissipation pipe 305, and the first heat dissipation fin 304 and the second heat dissipation fin 306 are tightly attached to the heat dissipation pipe 305. The cooling fan 303 includes a motor and fan blades. Multiple small protrusions are provided on the surfaces of the first heat dissipation fin 304 and the second heat dissipation fin 306.

[0027] Multiple tiny protrusions on the surfaces of the first heat dissipation fin 304 and the second heat dissipation fin 306 increase the degree of air disturbance with their surfaces, enabling the air to carry away heat more efficiently from the first heat dissipation fin 304, the second heat dissipation fin 306 and the heat pipe 305. Under the synergistic effect of this series of structures, the heat exchange rate is greatly improved.

[0028] Specifically, the heat dissipation pipe 305 is spirally arranged on the outer surface of the oil cavity 201, which greatly increases the heat exchange path length between the oil and the outside air. At the same time, the first heat dissipation fin 304 and the second heat dissipation fin 306 are closely attached to the heat dissipation pipe 305, further expanding the heat dissipation area. The cooling fan 303 installed in the rear cover 301 drives the fan blades to rotate through the motor, forming a forced airflow. The air inlet net 302 can prevent foreign objects from entering and protect the cooling fan 303. The forced air cooling method allows air to flow quickly through the heat dissipation fins and heat dissipation pipe 305, which greatly improves the heat exchange rate compared with natural air cooling, ensuring that the cooler can dissipate heat efficiently under various operating conditions.

[0029] Working principle of this utility model: This utility model is a high-efficiency air-cooled oil cooler. When the high-efficiency air-cooled oil cooler starts working, hot oil first flows into the oil chamber 201 from the oil inlet 202. Inside the oil chamber 201, multiple sets of regularly and orderly alternating first guide plates 204 and second guide plates 205 play a role. After the oil hits the first guide plates 204 and second guide plates 205, its flow direction changes continuously, forming a tortuous and uniform flow path. This flow mode effectively avoids the occurrence of dead zones or uneven local flow velocity in the oil chamber 201, allowing the oil to more fully contact the heat dissipation components 3 installed on the outer surface of the oil chamber 201, greatly increasing the contact area and contact time, and initially improving the heat exchange efficiency. At the same time, the subsequent... The cooling fan 303 inside the cover 301 starts to run. The motor of the cooling fan 303 drives the fan blades to rotate at high speed, drawing in outside air through the air inlet net 302, thereby forming a forced airflow inside the cooler. The air inlet net 302 can effectively block dust, debris and other foreign objects from entering, playing a role in protecting the cooling fan 303. The forced airflow quickly sweeps over the heat dissipation component 3. The heat dissipation pipe 305 is spirally arranged on the outer surface of the oil cavity 201, extending the contact path between the air and the heat dissipation pipe 305. The first heat dissipation fins 304 and the second heat dissipation fins 306, which are closely attached to the heat dissipation pipe 305, further expand the heat dissipation area, ensuring efficient heat dissipation of the cooler, and finally achieving effective cooling of the oil. The cooled oil flows out from the oil outlet 203, completing the entire cooling cycle. At this point, the entire process ends.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
