TECHNICAL FIELD

[0001] The present application relates to, but is not limited to, the technical field of air conditioning equipment, in particular to a corrugated connecting pipe, an air conditioner outdoor unit and an air conditioner. BACKGROUND

[0002] The existing corrugated connecting pipe applied to the air conditioner outdoor unit includes a corrugated pipe and a woven mesh sleeve arranged on the outer surface of the corrugated pipe. The exhaust port of the compressor assembly of the air conditioner outdoor unit is connected to the air inlet of the four-way valve assembly of the air conditioner outdoor unit through the corrugated pipe. When the corrugated connecting pipe is used on the air conditioner outdoor unit, the crests on the outer surface of the corrugated pipe often crack and leak. SUMMARY

[0003] Analysis and research found that when the corrugated pipe vibrates, the distance between adjacent crests on the outer surface of the corrugated pipe changes. At this time, the stress generated on the corrugated pipe is concentrated on the crests on the outer surface of the corrugated pipe, which easily causes the crests on the outer surface of the corrugated pipe to crack and leak.

[0004] The present application provides a corrugated connecting pipe, which includes a corrugated pipe and a damping layer arranged on the outer surface of the corrugated pipe to improve the vibration resistance of the corrugated pipe.

[0005] In some example embodiments, the damping layer includes a ring-shaped main body portion, wherein the corrugated pipe is located on the inner side of the main body portion; and a plurality of ring-shaped protruding portions located on the inner side of the main body portion, axially spaced apart from each other, and radially connected to the inner surface of the main body portion; wherein the mating recesses are formed between adjacent protruding portions, the crests on the outer surface of the corrugated pipe are one-to-one correspondingly arranged in the mating recesses and connected to the inner surface of the mating recesses, the protruding portions are embedded between adjacent crests on the outer surface of the corrugated pipe and spaced apart from the valleys between the adjacent crests.

[0006] In some example embodiments, the depth of the protruding portions embedded between adjacent crests on the outer surface of the corrugated pipe is 1 / 4 to 1 / 2 of the wave height of the outer surface of the corrugated pipe.

[0007] In some example embodiments, the thickness of the bottom wall of the mating recess is 1mm to 3mm.

[0008] In some example embodiments, the material of the damping layer is butyl rubber, asphalt-based damping glue or silicone.

[0009] In some example embodiments, the material of the corrugated pipe is magnesium alloy, aluminum alloy, nylon or polytetrafluoroethylene.

[0010] In some example embodiments, the corrugated connecting pipe further includes a protective sleeve arranged outside the damping layer.

[0011] In some example embodiments, the protective sleeve is a braided mesh sleeve.

[0012] The application also provides an air conditioner outdoor unit, comprising a compressor assembly, a four-way valve assembly and the corrugated connecting pipe according to any one of the above embodiments, wherein the exhaust port of the compressor assembly is connected to the air inlet of the four-way valve assembly through the corrugated pipe.

[0013] The application also provides an air conditioner, comprising the air conditioner outdoor unit according to any one of the above embodiments.

[0014] The corrugated connecting pipe according to the application has the damping layer arranged on the outer surface of the corrugated pipe, which can absorb the vibration energy of the corrugated pipe to prevent the corrugated pipe from continuing to vibrate, so that the corrugated pipe has better vibration resistance and is less likely to have stress concentration at the wave crest of the outer surface due to vibration, and therefore the wave crest of the outer surface of the corrugated pipe is less likely to crack and leak; in addition, the damping layer arranged on the outer surface of the corrugated pipe also insulates the corrugated pipe from water vapor in the external environment, preventing the corrugated pipe from being corroded by water vapor in the external environment, and therefore the corrugated pipe has better corrosion resistance and is less likely to have perforation leakage.

DETAILED DESCRIPTION

[0019] In order to make the objects, technical solutions and advantages of the present application clearer, below the embodiments of the present application will be described in detail with reference to the drawings. It should be explained that the embodiments in the present application and the features in the embodiments can be combined with each other in any manner without conflict.

[0020] The analysis and research found that when the corrugated pipe vibrates, the distance between the adjacent wave crests on the outer surface of the corrugated pipe changes, at this time the stress generated on the corrugated pipe concentrates on the wave crests on the outer surface of the corrugated pipe, which is easy to cause the wave crests on the outer surface of the corrugated pipe to crack and leak.

[0021] The corrugated connecting pipe provided by the embodiments of the present application comprises a corrugated pipe 100 and a damping layer 200 provided on the outer surface of the corrugated pipe 100 to improve the vibration resistance of the corrugated pipe 100. Figure 1

[0022] The corrugated connecting pipe, the damping layer 200 provided on the outer surface of the corrugated pipe 100 can absorb the vibration energy of the corrugated pipe 100 to prevent the corrugated pipe 100 from continuing to vibrate, so that the vibration resistance of the corrugated pipe 100 is better, and the wave crests on the outer surface of the corrugated pipe 100 are less likely to concentrate stress and crack and leak due to vibration. Therefore, the wave crests on the outer surface of the corrugated pipe 100 in this scheme are less likely to crack and leak. In addition, the damping layer 200 provided on the outer surface of the corrugated pipe 100 also isolates the corrugated pipe 100 from water vapor in the external environment, preventing the corrugated pipe 100 from being corroded by water vapor in the external environment, so that the corrosion resistance of the corrugated pipe 100 in this scheme is also better, and the corrugated pipe 100 is less likely to be perforated and leak.

[0023] In some examples, as shown in Figure 1 The damping layer 200 comprises a ring-shaped main body portion 210, and a plurality of ring-shaped protruding portions 220 located on the inner side of the main body portion 210 and arranged axially spaced apart on the main body portion 210, and the radially outer end of each protruding portion 220 is connected with the inner surface of the main body portion 210. Wherein, the adjacent protruding portions 220 form a matching recess portion 230, the wave crests on the outer surface of the corrugated pipe 100 are one-to-one placed in the matching recess portion 230 and connected with the inner surface of the matching recess portion 230, and the protruding portion 220 is embedded between the adjacent wave crests on the outer surface of the corrugated pipe 100 and spaced apart from the valleys between the adjacent wave crests.

[0024] ​The wave crest of the outer surface of the corrugated pipe 100 is arranged in the matching recess 230 and connected with the inner surface of the matching recess 230, so that the connecting area of the outer surface of the corrugated pipe 100 and the damping layer 200 is larger, the connecting strength is higher, the outer surface of the corrugated pipe 100 and the damping layer 200 are less likely to be separated from each other, so that the damping layer 200 has a better effect of preventing the corrugated pipe 100 from vibrating, that is, the corrugated pipe 100 has better vibration resistance. The convex part 220 and the wave trough of the outer surface of the corrugated pipe 100 are radially spaced apart, which can alleviate the problem of reducing the flexibility of the corrugated pipe 100 caused by the damping layer 200, and ensure that the combined structure of the corrugated pipe 100 and the damping layer 200 still has good flexible deformation capability.

[0025] In some examples, as shown in Figure 1 The depth of the convex part 220 embedded between adjacent wave crests of the outer surface of the corrugated pipe 100 is 1 / 4 to 1 / 2 of the wave height h of the outer surface of the corrugated pipe 100, so that not only the corrugated pipe 100 has good vibration resistance, but also the wave crest of the outer surface of the corrugated pipe 100 is less likely to crack and leak, and the flexible deformation capability of the combined structure of the corrugated pipe 100 and the damping layer 200 is also good, and the corrugated connecting pipe is more easily bent.

[0026] The depth of the convex part 220 embedded between adjacent wave crests of the outer surface of the corrugated pipe 100 can be 1 / 4 of the wave height h of the outer surface of the corrugated pipe 100; or the depth of the convex part 220 embedded between adjacent wave crests of the outer surface of the corrugated pipe 100 can be 1 / 3 of the wave height h of the outer surface of the corrugated pipe 100; or the depth of the convex part 220 embedded between adjacent wave crests of the outer surface of the corrugated pipe 100 can be 1 / 2 of the wave height h of the outer surface of the corrugated pipe 100, etc.; all of the above can achieve the purpose of the present application, and the purpose does not deviate from the design idea of the present application, and will not be described here again, and all should be within the protection scope of the present application.

[0027] In some examples, as shown in Figure 1 The thickness d of the bottom wall of the matching recess 230 in the radial direction of the corrugated pipe 100 is 1mm to 3mm, so that the damping layer 200 has a good corrosion prevention effect on the corrugated pipe 100, and the corrugated pipe 100 is less likely to be perforated and leaked by water vapor in the external environment.

[0028] The thickness d of the bottom wall of the matching recess 230 can be 1mm; or the thickness d of the bottom wall of the matching recess 230 can be 2mm; or the thickness d of the bottom wall of the matching recess 230 can be 3mm, etc.; all of the above can achieve the purpose of the present application, and the purpose does not deviate from the design idea of the present application, and will not be described here again, and all should be within the protection scope of the present application.

[0029] The material of the damping layer 200 can be butyl rubber, asphalt-based damping glue or silicone, all of which can achieve the purpose of the present application, and the purpose does not deviate from the design idea of the present application, and will not be described here again, and all should be within the protection scope of the present application.

[0030] The butyl rubber, asphalt-based damping glue or silicone is formed into the damping layer 200 on the outer surface of the corrugated pipe 100 by using a vulcanization process. This scheme is simple in process and mature in technology.

[0031] The material of the corrugated pipe 100 can be magnesium alloy, aluminum alloy, nylon or polytetrafluoroethylene, all of which can achieve the purpose of the present application, and the purpose does not deviate from the design idea of the present application, and will not be described here again, and all should be within the protection scope of the present application.

[0032] The magnesium alloy and the aluminum alloy are good in flexibility and easy to be made into the corrugated pipe 100. Compared with steel material and stainless steel material, the magnesium alloy, the aluminum alloy, the nylon and the polytetrafluoroethylene all have certain damping effect, and the combination structure of the corrugated pipe 100 and the damping layer 200 has better vibration resistance.

[0033] In some examples, as shown in Figure 1 The corrugated connecting pipe further includes a protective sleeve 300 arranged outside the damping layer 200 to protect the damping layer 200 from scratching and bumping.

[0034] The protective sleeve 300 is arranged as a woven mesh sleeve, and the woven mesh sleeve is mature in manufacturing process.

[0035] The woven mesh sleeve can be arranged in one layer, or in two layers, or in three layers, all of which can achieve the purpose of the present application, and the purpose does not deviate from the design idea of the present application, and will not be described here again, and all should be within the protection scope of the present application.
