Its main function is to cool the steering system lubricating oil to ensure that the steering system components such as the transmission, differential and other components operate at normal operating temperatures, thereby extending the service life of each component of the steering system and improving the overall performance of the car.

[0003] The main structure of the current steering system oil cooler includes an oil cooling tube body and a plurality of heat sinks; the oil cooling tube body has an oil cooling channel; the plurality of heat sinks are arranged outside the oil cooling tube body. When in use, a cooling fan is installed on the plurality of heat sinks, and the oil with heat flows in from one end of the oil cooling channel, then flows through the oil cooling channel, and flows out from the other end. In the process of flowing through the oil cooling channel, the heat of the oil is transferred to the plurality of heat sinks through the oil cooling tube body, and finally, the wind generated by the cooling fan takes away the heat from the plurality of heat sinks.

[0004] However, the oil cooling pipe of the steering system oil cooler is a hollow pipe, which is easy to be bent or dented, has a relatively weak structural strength, and has poor heat dissipation performance compared to OE original products. Therefore, it is necessary to improve the current steering system oil cooler. Utility Model Content

[0008] As a preferred solution, the oil cooling tube body is an aluminum tube, and the heat dissipation profile is an aluminum extruded profile, which has good structural strength, low cost and good thermal conductivity.

[0009] As a preferred solution, the heat dissipation profile includes a straight tube portion and a plurality of fin portions radiating outward from the outer wall of the straight tube portion. The straight tube portion has an inner flow channel with front and rear ends open. The outer side surface of each fin portion is tightly matched with the inner wall of the oil cooling channel, and an outer flow channel is formed between two adjacent fin portions to better increase the heat dissipation area.

[0010] As a preferred solution, the oil cooling tube body is U-shaped, and correspondingly, the oil cooling channel is also U-shaped. The oil cooling channel includes two straight sections connected to a curved section between the two straight sections. There are two heat dissipation profiles, which are respectively arranged in the two straight sections to better dissipate the heat of the oil.

[0011] As a preferred solution, both ends of the oil cooling tube body are welded with external joints, and the two external joints are respectively connected to the input end and the output end of the oil cooling channel so as to be connected to the external oil circuit.

[0012] As a preferred solution, a mounting bracket fixedly mounted to the outside is provided on the oil cooling pipe body so as to be mounted and fixed to the outside.

[0013] Compared with the prior art, the utility model has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0014] By arranging a heat dissipation profile in the oil cooling channel and closely fixing the heat dissipation profile to the inner wall of the oil cooling channel, the traditional hollow tube structure is replaced, the structural strength is effectively enhanced, and it is avoided that it is easy to be bent or dented.

[0026] Please refer to Figures 1 to 3 As shown, it shows the specific structure of a preferred embodiment of the utility model, including an oil cooling tube body 10 and a plurality of heat sinks 20.

[0027] The oil cooling tube body 10 has an oil cooling channel 11 in it, and a heat dissipation profile 30 is arranged in the oil cooling channel 11, and the heat dissipation profile 30 is tightly matched and fixed with the inner wall of the oil cooling channel 11. In this embodiment, the oil cooling tube body 10 is an aluminum tube, which has good structural strength, low cost and good thermal conductivity. Specifically, the oil cooling tube body 10 is U-shaped, and correspondingly, the oil cooling channel 11 is also U-shaped. The oil cooling channel 11 includes two straight sections 111 connected to a curved section 112 between the two straight sections 111. There are two heat dissipation profiles 30, and the two heat dissipation profiles 30 are respectively arranged in the two straight sections 111.

[0028] The plurality of heat sinks 20 are disposed outside the oil cooling tube body 10. In this embodiment, the plurality of heat sinks 20 are arranged on the oil cooling tube body 10 in a dense array.

[0029] The heat dissipation profile 30 is an aluminum extruded profile with a simple structure, good heat dissipation and low cost. Specifically, the heat dissipation profile 30 includes a straight tube portion 31 and a plurality of fin portions 32 radiating outward from the outer wall of the straight tube portion 31. The straight tube portion 31 has an inner flow channel 301 with openings at both ends. The outer side surface of each fin portion 32 is tightly matched with the inner wall of the oil cooling channel 11, and an outer flow channel 302 is formed between two adjacent fin portions 32 to better increase the heat dissipation area.

[0030] Furthermore, both ends of the oil cooling pipe body 10 are welded with external joints 40, and the two external joints 40 are respectively connected to the input end and the output end of the oil cooling channel 11, so as to be connected to the external oil circuit. In addition, the oil cooling pipe body 10 is provided with a mounting bracket 50 fixedly mounted to the outside, so as to be fixedly mounted to the outside, and the mounting bracket 50 is arranged in multiple intervals, so that the whole product is firmly mounted to the outside.

[0031] The production process and use method of this embodiment are described in detail as follows:

[0032] During the manufacturing process, a plurality of heat sinks 20 and mounting brackets 50 are fixed on the oil cooling tube body 10, and then two heat dissipation profiles 30 are placed in the straight section 111 of the oil cooling tube body 10. The heat dissipation profiles 30 are tightly matched with the inner wall of the straight section 111. Then, two external joints 40 are welded to the two ends of the oil cooling tube body 10, so as to form an oil inlet and outlet circuit.

[0033] When in use, the two external connectors 40 are respectively connected to the oil circuit of the automobile steering system, and a cooling fan is installed on the multiple heat sinks 20. When working, the hot oil enters from one of the external connectors 40, then flows through the oil cooling channel 11, and flows out from the other external connector 40. In the process of flowing through the oil cooling channel 11, the heat dissipation profile 30 and the oil cooling tube body 10 absorb the heat of the oil, and the heat is transferred to the multiple heat sinks 20. Finally, the wind generated by the cooling fan takes away the heat from the multiple heat sinks 20, thereby realizing the cooling of the oil. The cooled oil is output and refluxed to the automobile steering system for reuse.

[0034] The design focus of the utility model is that a heat dissipation profile is arranged in the oil cooling channel, and the heat dissipation profile is closely matched and fixed to the inner wall of the oil cooling channel, thereby replacing the traditional hollow tube structure, effectively enhancing the structural strength, and avoiding easy bending or depression. At the same time, the heat dissipation profile can increase the heat dissipation area inside the oil cooling tube body, thereby achieving the purpose of high heat dissipation efficiency and oil cooling. The overall structure of this product is simple, easy to manufacture, low cost, and worthy of promotion and application.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the technical scope of the present invention. Therefore, any slight modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention are still within the scope of the technical solution of the present invention.
