Detailed Description

It should be noted that the embodiments and features of the embodiments may be combined with each other without conflict.

The present invention will be described in detail with reference to fig. 3 to 5 in conjunction with embodiments.

As shown in fig. 3 to 5, the mesocooling pipe assembly 1000 according to the embodiment of the present invention includes: intercooling hose 100 and cushioning member 200.

Wherein, as shown in fig. 3, the intercooling hose 100 is provided with fasteners 300 at both axial ends thereof. The fastener 300 is mainly used to achieve the connection of the intercooling hose 100 with the external piping.

In some examples, the intercooling pipe assembly 1000 further comprises an air inlet pipe and an air outlet pipe (not shown), which are respectively connected to both ends of the intercooling hose 100 through fasteners 300. That is, the fastener 300 is disposed at both axial ends of the intercooling hose 100, so that the intercooling hose 100 is connected to the air inlet pipe and the air outlet pipe by the fastener 300, the connection strength is increased, the connection difficulty is reduced, and the intercooling pipe assembly 1000 is formed.

Alternatively, the fastener 300 is a tightening hoop that is sleeved over the intercooling hose 100. The intercooling hose 100 and the air inlet pipe are connected through the fastening hoop, and the intercooling hose 100 and the air outlet pipe are connected, so that the assembly difficulty of the intercooling pipe assembly 1000 is further reduced, and the assembly efficiency of the intercooling pipe assembly 1000 is improved. The structure of the fastening hoop and the assembling process using the fastening hoop are well known in the art, and are not described herein.

As shown in fig. 4 and 5, the damper 200 is provided in the pipe wall of the intercooler hose 100, the damper 200 extends in the axial direction of the intercooler hose 100, and the projection of the fastener 300 on the developed surface of the intercooler hose 100 coincides with the projection of the damper 200 on the developed surface, so that at least a part of the damper 200 can be provided facing the fastener 300. That is, the buffer member 200 is disposed inside the tube wall of the intercooler hose 100 near the fastener 300 while the buffer member 200 is further extended in the axial direction of the intercooler hose 100 to have a certain length of the buffer member 200 inside the tube wall of the intercooler hose 100 so that a part of the structure of the buffer member 200 can be disposed facing the fastener 300.

Because the two axial ends of the intercooling hose 100 are provided with the fastening hoop, and the two ends of the intercooling hose 100 are respectively connected with the air inlet pipe and the air outlet pipe by using the fastening hoop, after the intercooling hose 100 is connected with the air inlet pipe and the air outlet pipe, the inner wall surface of the fastening hoop can tightly tighten part of the outer peripheral wall 150 of the intercooling hose 100, so that when high-temperature and high-pressure fluid flows into the intercooling hose 100 to cause outward expansion and deformation of the intercooling hose 100, the tightened part of the intercooling hose 100 cannot deform, the outward expansion and deformation of the part of the intercooling hose 100 which is not tightened by the fastening hoop can increase the included angle between the tightened part of the intercooling hose 100 and the part of the intercooling hose 100 which is not tightened by the fastening hoop, and thus after the intercooling hose 100 works for a period, because the part of the intercooling hose 100 which is not tightened by the fastening hoop expands and contracts frequently relative to the tightened part of the intercooling hose 100, the tearing breakage of the intercooler hose 100 between the portion of the intercooler hose 100 which is not tightened by the tightened hoop and the portion of the intercooler hose 100 which is tightened, that is, the breakage of the intercooler hose 100, is caused, the service life of the intercooler hose 100 is shortened, and the reliability of the intercooler hose 100 is also reduced.

Therefore, the present application provides the buffer 200 in the wall of the intercooling hose 100 near the buffer 200, this buffer member 200 provides additional support to the tube wall of the intercooler hose 100 when the fluid of high temperature and high pressure collides with the intercooler hose 100 to be expanded and deformed outward, so that the intercooler hose 100 is expanded and deformed outward at the portion which is not tightened by the fastening hoop, the included angle between the part of the intercooling hose 100 which is tightened and the part of the intercooling hose 100 which is not tightened by the fastened hoop can be reduced, the expansion rate of the position of the intercooling hose 100 corresponding to the fastened hoop is controlled to be 3% -8%, so that the deformed intercooling hose 100 can be smoothly transited, thereby avoiding the tearing breakage of the intercooling hose 100 when the intercooling hose is deformed, improving the capability of resisting the expansion deformation impact of the intercooling hose 100, meanwhile, the service life of the intercooling hose 100 is prolonged, and the use reliability of the intercooling hose 100 is improved.

As can be seen from the above structure, in the intercooling hose assembly 1000 according to the embodiment of the present invention, the buffer member 200 is disposed in the tube wall of the intercooling hose 100, when the intercooling hose 100 undergoes expansion deformation, the buffer member 200 provides a buffer support for the intercooling hose 100 close to the fastening member 300 and inhibits the intercooling hose 100 from continuing to deform after deforming to a certain extent, so that the expansion rate of the intercooling hose 100 close to the fastening member 300 is smoothed and excessive, an included angle between a portion of the intercooling hose 100 that is tightened by the fastening member 300 and a portion of the intercooling hose 100 that is not tightened by the fastening member 300 is reduced, and it is ensured that the intercooling hose 100 does not break due to reaching the upper limit of the elongation at break, that is, the intercooling hose 100 is prevented from breaking due to excessive stretching.

That is, the buffer 200 disposed in the wall of the intercooling hose 100 can control the expansion rate and the tensile deformation of the intercooling hose 100, so as to prevent the intercooling hose 100 from being broken, thereby prolonging the service life of the intercooling hose 100, improving the reliability of the intercooling hose 100, and ensuring that the intercooling hose assembly 1000 can constantly maintain the pressurization pressure.

In addition, this application sets up bolster 200 in intercooling hose 100's pipe wall, can avoid bolster 200 to occupy the outside space of intercooling hose 100 to ensure under the prerequisite that does not change bolster 200, fastener 300, intake pipe and outlet duct structure, each subassembly in well cold tube assembly 1000 can also carry out effective connection, thereby reduce cold tube assembly 1000's in this application manufacturing degree of difficulty. Meanwhile, the appearance of the intercooling pipe assembly 1000 cannot be affected by the arrangement, and the production cost of the intercooling pipe assembly 1000 cannot be increased too much.

That is, in the present invention, the cushion member 200 is provided, so that the expansion rate and the tensile deformation amount of the intercooler hose 100 can be controlled, and the appearance and the assembly of the intercooler pipe assembly 1000 are not affected.

In some examples, when intercooling hose 100 is molded by extrusion, the buffer member 200 may be inserted into the wall of intercooling hose 100 by external force after molding intercooling hose 100, so as to provide buffer member 200 in the wall of intercooling hose 100.

In other examples, when the intercooling hose 100 is manufactured and molded by a weaving or winding process, the buffer member 200 may be fitted into the tube wall of the intercooling hose 100 during the molding of the intercooling hose 100, so as to provide the buffer member 200 in the tube wall of the intercooling hose 100.

It can be understood that, compared with the prior art, the present application provides the buffer 200 on the tube wall of the intercooling hose 100 to control the expansion rate and the tensile deformation of the intercooling hose 100, and avoid the occurrence of the permanent fracture deformation of the intercooling hose 100 due to the fatigue failure of the intercooling hose 100 caused by frequent expansion and contraction of the end portion of the intercooling hose 100.

Optionally, the bumper 200 is made of polypropylene, nylon, or a thermoplastic polyester elastomer. The buffer piece 200 has a certain elastic deformation force and a certain strength, so that when the intercooling hose 100 generates expansion deformation, the buffer piece 200 can also synchronously deform along with the intercooling hose 100 and inhibit the expansion rate of the intercooling hose 100 in the deformation process, thereby ensuring that the intercooling hose 100 cannot be broken due to reaching the upper limit of the expansion rate, namely avoiding the intercooling hose 100 from being broken due to over-stretching.

Alternatively, the intercooler hose 100 may be made of a rubber-like material, so that the intercooler hose 100 has a deformation capability without breaking during a slight deformation, and the intercooler hose 100 can have a capability of recovering its original shape after being deformed and the external force disappears.

In some examples, intercooling hose 100 may be made from a rubber-like material such as high temperature acrylate rubber, ethylene acrylate rubber, chlorinated polyethylene, chlorinated rubber, or nitrile rubber.

In some embodiments of the present invention, the buffer 200 is formed as a buffer post. That is, the buffer member 200 is formed in a columnar structure, so that while the buffer member 200 can effectively provide buffering support for the intercooling hose 100, the assembling difficulty of the buffer member 200 and the intercooling hose 100 can be reduced, and the buffer member 200 can be easily and quickly assembled in the pipe wall of the intercooling hose 100.

Alternatively, when the intercooler hose 100 is manufactured and molded by a weaving or winding process, the buffer member 200 is not limited to be formed as the buffer post as described above, but the buffer member 200 may be formed in a ring structure having an inner diameter larger than that of the intercooler hose 100 to ensure that the buffer member 200 formed in the ring structure can be disposed in the inner wall of the intercooler hose 100.

Alternatively, as shown in fig. 4 and 5, when the buffer member 200 is formed as a buffer post, the buffer post includes a plurality of buffer posts, and the plurality of buffer posts are provided at intervals in the circumferential direction of the intercooling hose 100. The plurality of cushion columns cooperate to cushion and support the intercooling hose 100 at different positions on the circumference of the intercooling hose 100, and avoid the intercooling hose 100 from breaking when expanding and deforming.

It should be noted that, compared to the ring-shaped structure of the buffer member 200, the buffer member 200 is configured as a buffer column, which can reduce the production cost of the buffer member 200 and the difficulty of assembling the buffer member 200 and the intercooling hose 100.

In some examples, when the dampers 200 are formed as buffer posts, 6 to 18 buffer posts may be provided in the tube wall of the intercooling hose 100, with 6 to 18 buffer posts being spaced circumferentially of the intercooling hose 100.

It should be noted that when the number of the buffer columns arranged in the tube wall of the intercooling hose 100 is small, the buffer columns cannot effectively buffer and support the intercooling hose 100 at different positions on the circumference of the intercooling hose 100, so that the intercooling hose 100 is at risk of breaking during expansion and deformation; when the number of the buffer columns disposed in the tube wall of the intercooling hose 100 is large, on one hand, the production cost of the buffer 200 is increased, on the other hand, the weight of the intercooling hose 100 is also increased, and the difficulty in assembling the intercooling hose 100 and the buffer 200 is increased. Therefore, the 6-18 buffering columns are arranged in the tube wall of the intercooling hose 100, so that the production cost of the buffering piece 200 can be reduced, the weight of the intercooling hose 100 can be reduced, and the assembling difficulty between the buffering piece 200 and the intercooling hose 100 can be reduced while the buffering columns can effectively buffer and support the intercooling hose 100.

In some specific examples, 6, 8, 10, 12, 14, 16, or 18 bumper posts may be disposed within the wall of intercooling hose 100.

Of course, in other examples, the number of the buffer columns may be reasonably selected by those skilled in the art according to the diameter of the intercooling hose 100, where when the diameter of the intercooling hose 100 is larger, a larger number of the buffer columns may be disposed in the pipe wall of the intercooling hose 100, and when the diameter of the intercooling hose 100 is smaller, a smaller number of the buffer columns may be disposed in the pipe wall of the intercooling hose 100, as long as the buffer columns are ensured to effectively buffer and support the intercooling hose 100.

Optionally, the diameter of the buffer column is D, wherein D is more than or equal to 0.3mm and less than or equal to 0.8 mm. When the diameter of the buffer column is smaller, the structural strength of the buffer column can be reduced, so that the buffer column cannot effectively buffer and support the intercooling hose 100, and the intercooling hose 100 has a risk of fracture when being expanded and deformed; when the diameter of the buffer post is large, the production cost of the buffer member 200 increases on the one hand, and the weight of the intercooling hose 100 increases on the other hand. Therefore, the diameter of the buffering column is set to be 0.3 mm-0.8 mm, the buffering column can effectively buffer and support the intercooling hose 100, the production cost of the buffering piece 200 can be reduced, and the weight of the intercooling hose 100 can be reduced.

In some embodiments of the present invention, as shown in fig. 4, the extension length of the buffer member 200 is greater than that of the fastener 300 in the axial direction of the intercooling hose 100. This ensures that part of the structure of the buffer 200 can be arranged in the tube wall of the part of the intercooler hose 100 that is not tightened by the fastener 300, thus ensuring that the buffer 200 can effectively buffer and support the deformed intercooler hose 100 when the part of the intercooler hose 100 that is not tightened by the fastener 300 is subjected to expansion deformation.

Alternatively, as shown in fig. 3, the intercooling hose 100 includes a first pipe segment 110, a second pipe segment 120, and a third pipe segment 130, the first pipe segment 110 and the second pipe segment 120 are formed in a straight structure, the third pipe segment 130 is connected between the first pipe segment 110 and the second pipe segment 120, and the third pipe segment 130 is formed in a bendable structure. That is, part of the piping (the third pipe section 130) of the intercooler hose 100 can be bent, and part of the piping (the first pipe section 110 and the second pipe section 120) of the intercooler hose 100 can not be bent, wherein the unbendable first pipe section 110 and the unbendable second pipe section 120 are arranged at both axial ends of the intercooler hose 100, so as to facilitate the arrangement of the buffers 200 at both axial ends of the intercooler hose 100, and the bendable third pipe section 130 is arranged between the first pipe section 110 and the second pipe section 120, thereby ensuring that the whole structure of the intercooler hose 100 can be bent, so that when the intercooler hose 100 is arranged, the shape of the intercooler hose 100 can be adjusted, so as to reduce the arrangement difficulty of the intercooler hose 100.

Alternatively, as shown in fig. 4, the extension length of the buffer member 200 is smaller than that of the first tube segment 110. Here, when the buffering member 200 is disposed in the tube wall of the first tube segment 110, the extending length of the buffering member 200 is less than the extending length of the first tube segment 110, and because the bendable third tube segment 130 is connected to one end of the first tube segment 110, the buffering member 200 is disposed so as to prevent the buffering member 200 from extending into the tube wall of the third tube segment 130, so that the buffering member 200 can prevent the third tube segment 130 from bending while reducing the production cost of the buffering member 200, that is, the buffering member 200 can prevent the third tube segment 130 from bending normally when the intercooler hose 100 is disposed.

Optionally, the extension length of the buffer 200 is smaller than the extension length of the second tube segment 120. Here, when the buffer 200 is disposed in the tube wall of the second tube segment 120, the extending length of the buffer 200 is less than the extending length of the second tube segment 120, and the beneficial effects of the buffer 200 that the extending length is less than the extending length of the first tube segment 110 are described, which is not described herein again.

Optionally, as shown in fig. 4, the buffer member 200 has a first end 210 and a second end 220, wherein the first end 210 of the buffer member 200 is disposed close to the nozzle 140 of the intercooling hose 100, the second end 220 of the buffer member 200 is disposed away from the nozzle 140 of the intercooling hose 100, and a distance between the second end 220 and the nozzle 140 is L1, where L1 is greater than or equal to 25mm and less than or equal to 35 mm. When the distance between the second end 220 of the buffer member 200 and the nozzle 140 is small, the structural strength of the buffer member 200 itself is reduced, and at the same time, the extension length of the buffer member 200 in the axial direction of the intercooling hose 100 may be smaller than the extension length of the fastener 300, so that the buffer member 200 cannot effectively buffer and support the intercooling hose 100, and the intercooling hose 100 may be broken when being expanded and deformed; when the distance between the second end 220 of the buffer member 200 and the nozzle 140 is relatively large, on one hand, the production cost and the structural weight of the buffer member 200 are increased, and on the other hand, the extension length of the buffer member 200 may be longer than the extension length of the first tube segment 110 or the second tube segment 120, so that a part of the third tube segment 130 cannot be effectively bent.

Therefore, the distance between the second end 220 of the buffer member 200 and the pipe orifice 140 is set to be 25 mm-35 mm, the extending length of the buffer member 200 can be ensured to be larger than that of the fastener 300, and simultaneously, the extending length of the buffer member 200 can be ensured to be smaller than that of the first pipe section 110 or the second pipe section 120, so that the buffer member 200 can effectively buffer and support the intercooling hose 100, the third pipe section 130 can be ensured to be normally bent, the production cost of the buffer member 200 can be reduced, and the weight of the intercooling hose 100 can be reduced.

In some embodiments of the present invention, as shown in fig. 4, intercooling hose 100 has an outer circumferential wall 150 and an inner circumferential wall 160 disposed opposite to each other, and bumpers 200 are disposed spaced apart from the outer circumferential wall 150 of intercooling hose 100 and the inner circumferential wall 160 of intercooling hose 100. Thereby ensuring that the buffer member 200 can be disposed inside the peripheral wall of the intercooler hose 100, avoiding the buffer member 200 from occupying the outer space of the intercooler hose 100, that is, avoiding the buffer member 200 from affecting the appearance and assembly of the intercooler pipe assembly 1000.

Alternatively, as shown in FIG. 4, the distance between the bumper 200 and the outer peripheral wall 150 of the intercooler hose 100 is L2, 1.5mm L2 mm 2.5 mm. To ensure that the bumper 200 can be disposed between the outer peripheral wall 150 of the intercooler hose 100 and the inner peripheral wall 160 of the intercooler hose 100, that is, to ensure that the bumper 200 can be disposed within the tube wall of the intercooler hose 100.

Meanwhile, the buffer member 200 can be spaced from the outer peripheral wall 150 of the intercooling hose 100 by a certain distance through the arrangement, so that the buffer member 200 is prevented from extending out of the pipe wall of the intercooling hose 100 when the intercooling hose 100 is expanded and deformed, namely, the buffer member 200 can be stably arranged in the pipe wall of the intercooling hose 100, and the structural stability of the buffer member 200 is improved.

In some specific examples, the distance between the bumper 200 and the outer peripheral wall 150 of the intercooling hose 100 may be 1.5mm, 1.7mm, 2.0mm, 2.3mm, or 2.5 mm.

Alternatively, as shown in fig. 4, the distance between the bumper 200 and the outer circumferential wall 150 of the intercooling hose 100 is smaller than the distance between the bumper 200 and the inner circumferential wall 160 of the intercooling hose 100. That is, compared to the inner peripheral wall 160 of the intercooler hose 100, the buffer member 200 is disposed close to the outer peripheral wall 150 of the intercooler hose 100 to reduce the assembling difficulty of the buffer member 200, especially when the intercooler hose 100 is manufactured and molded by a weaving or winding process, specifically: through the arrangement, the buffer member 200 can be assembled after the side wall of the intercooling hose 100 is formed with a certain thickness, that is, the buffer member 200 can be assembled after the side wall of the intercooling hose 100 has certain structural strength, so that the intercooling hose 100 can effectively support the buffer member 200, and the buffer member 200 can be stably arranged in the pipe wall of the intercooling hose 100.

In addition, with the above arrangement, when the buffers 200 are formed as buffer columns, a larger number of buffers 200 can be arranged in the tube wall of the intercooling hose 100, and the multiple buffers 200 cooperate with the intercooling hose 100 to buffer and support, so as to avoid the intercooling hose 100 from breaking when expanding and deforming.

The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions, improvements, etc. within the spirit and principle of the present invention should be included in the protection scope of the present invention.
