[0002] In air conditioning systems, refrigerant undergoes phase changes and velocity variations during its circulation, which can easily trigger a series of fluid dynamics-related vibration and noise problems. Especially when the refrigerant flows at high speeds or the internal system pressure is unstable, the natural frequencies of the piping can be easily excited, leading to resonance. This resonance not only causes significant pipe vibration but also generates high-frequency whistling and other airflow noises, severely impacting the system's operational stability and the user experience.

Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The following is combined Figures 1-3 This invention describes a pipeline vibration damping device.

[0033] An embodiment of the first aspect of this utility model provides a pipeline vibration damping device, such as... Figure 1 and Figure 2 As shown, the pipeline vibration damping device includes a first vibration damping mechanism 100 and a second vibration damping mechanism 200.

[0034] The first vibration damping mechanism 100 includes a fixed ring 110 and a first vibration damping member 120. The first vibration damping member 120 is disposed inside the fixed ring 110 and has a mounting hole for mounting the pipe 300. The second vibration damping mechanism 200 includes a vibration damping component 210, which is sleeved on the fixed ring 110 and is used to absorb vibration kinetic energy.

[0035] Understandably, the first vibration damping mechanism 100 uses a fixed ring 110 and a built-in first vibration damping component 120. The fixed ring 110 fixes the pipe 300, and the first vibration damping component 120 is arranged between the fixed ring 110 and the pipe 300, thus the first vibration damping mechanism 100 achieves fixation and initial vibration damping of the pipe 300. The second vibration damping mechanism 200 uses a vibration damping component 210 arranged on the outer surface of the fixed ring 110. The vibration damping component 210 is mainly used to absorb the vibration kinetic energy of the pipe 300, forming a secondary vibration damping barrier to further improve the vibration damping effect. In this way, through the mutual cooperation of the first vibration damping mechanism 100 and the second vibration damping mechanism 200, the vibration and noise generated during the operation of the air conditioning system can be effectively reduced, so that users can obtain a better and more comfortable experience.

[0036] The pipeline vibration damping device provided in this embodiment of the utility model has a first vibration damping mechanism 100 arranged on the outside of the pipeline. The first vibration damping mechanism 100 adopts a fixing ring 110 and a built-in first vibration damping component 120 to achieve the fixation of the pipeline and initial vibration damping. A second vibration damping mechanism 200 is arranged on the outside of the fixing ring 110. The vibration damping component 210 of the second vibration damping mechanism 200 can effectively absorb the vibration kinetic energy generated during the operation of the system, further enhancing the vibration damping performance. It can effectively reduce the vibration and noise generated during the operation of the air conditioning system, thereby improving the user experience.

[0037] In one embodiment of this utility model, such as Figure 3 As shown, the vibration damping component 210 adopts a multi-layer composite form from the inside out. Specifically, the vibration damping component 210 includes a support frame 211, a damping layer 212, and an outer shell 213 arranged sequentially from the inside out. The vibration damping component 210 absorbs vibration kinetic energy sequentially from the inside out.

[0038] Optionally, the vibration damping layer 212 includes a flexible damping layer; the support frame 211 includes a honeycomb core layer.

[0039] In this embodiment, the supporting frame 211 adopts a honeycomb core layer structure, which is lightweight, high-strength, and has good energy absorption. It can effectively disperse and buffer the vibration energy from the pipeline while maintaining overall rigidity. The vibration damping layer 212 is set on the outside of the honeycomb core layer and is made of flexible silicone damping material. Utilizing its good elasticity and damping performance, it efficiently absorbs and dissipates the transmitted vibration kinetic energy, thereby significantly reducing the propagation intensity of noise. The outer shell 213 is made of carbon fiber, which not only has excellent mechanical strength and corrosion resistance, but also serves as an external protective layer, enhancing the structural stability and service life of the entire vibration damping component 210. Thus, through the synergistic effect of the honeycomb metal core, the flexible silicone damping layer, and the carbon fiber outer shell, the vibration damping component 210 achieves effective absorption and attenuation of sound vibration kinetic energy layer by layer from the inside out, thereby significantly reducing the noise generated during pipeline operation and creating a quieter and more comfortable operating environment for users.

[0040] Optionally, the vibration damping component 210 can employ two vibration damping supports, which are interlocked to form the vibration damping component 210, and the two vibration damping supports form an installation space adapted to the fixing ring. It should be noted that a connecting structure can be provided on the outside of the vibration damping component 210 to ensure a tight contact between the inner wall of the vibration damping component 210 and the outer wall of the fixing ring 110, thus ensuring effective transmission of vibration energy. For example, the connecting structure can be a connecting wire, thereby allowing the fit between the vibration damping component 210 and the fixing ring 110 to be adjustable, further optimizing the vibration damping performance.

[0041] According to an embodiment of the present invention, when the second vibration damping mechanism 200 includes a vibration damping component 210, the outer shell 213 can be connected to the inner wall of the air conditioner outdoor unit's casing to fix the vibration damping component 210. This effectively isolates the rigid connection between the pipeline and vibration sources such as the compressor, reduces the transmission of vibration along the pipeline, and thus achieves a good vibration damping effect.

[0042] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, the second vibration damping mechanism 200 also includes a vibration damping bracket 220, and the vibration damping component 210 is disposed inside the housing via the vibration damping bracket 220. Specifically, the first end of the vibration damping bracket 220 is connected to the fixing ring 110, and the second end of the vibration damping bracket 220 is connected to the inner wall of the outdoor unit's housing. Through the installation of the vibration damping bracket 220, auxiliary support and further vibration damping of the pipeline are achieved; thus, the vibration damping bracket 220 not only enhances the connection rigidity between the fixing ring 110 and the housing, but also effectively improves the support strength and stability of the entire pipeline, preventing displacement or shaking caused by vibration.

[0043] Optionally, multiple vibration damping brackets 220 can be installed as needed and distributed reasonably at different locations along the pipeline to form a multi-point support structure, thereby distributing the pipeline load more evenly and reducing local stress concentration. Furthermore, the vibration damping brackets 220 can also integrate vibration damping structures to further absorb and dissipate vibration energy, improve the overall vibration reduction and noise reduction effect, and ensure the safety and reliability of the system operation.

[0044] It should be noted that the first end of the vibration damping bracket 220 can also be connected to the vibration damping component 210; of course, the first end of the vibration damping bracket 220 can also be connected to both the vibration damping component 210 and the fixing ring 110 at the same time.

[0045] In this embodiment, the first vibration damping mechanism 100 is sleeved on the pipeline to achieve initial vibration damping and fixation of the pipeline. The second end (bottom) of the vibration damping bracket 220 is installed at the bottom of the air conditioner outdoor unit, serving as support and connection; the first end (top) of the vibration damping bracket 220 is simultaneously connected to the vibration damping component 210 and the fixing ring 110.

[0046] Specifically, the outer side wall of the fixing ring 110 has a first positioning part, the vibration damping component 210 has an installation port; the first end of the vibration damping bracket 220 passes through the installation port, and the vibration damping bracket 220 has a second positioning part that cooperates with the first positioning part, and the side wall of the vibration damping bracket 220 abuts against the side wall of the installation port.

[0047] The first positioning part and the second positioning part can adopt a matching positioning groove and positioning protrusion structure.

[0048] Understandably, the lower part of the vibration damping component 210 is provided with an installation port that matches the top of the vibration damping bracket 220. The first end (top) of the vibration damping bracket 220 passes through the installation port of the vibration damping component 210. The side wall of the installation port is in close contact with the outer wall of the vibration damping bracket 220, achieving a contact connection between the two. At the same time, the second positioning part at the top of the vibration damping bracket 220 and the first positioning part at the bottom of the fixing ring 110 cooperate to achieve a positioning connection between the vibration damping bracket 220 and the fixing ring 110. This forms a stable support and vibration damping system by integrating the first vibration damping mechanism 100, the vibration damping component 210, and the air conditioner outdoor unit. This not only enhances the overall rigidity of the structure but also helps to absorb and attenuate vibration energy step by step, further improving the vibration damping and noise reduction performance of the system.

[0049] In one embodiment of this utility model, such as Figure 1 and Figure 2 As shown, a second damping element 230 is provided at the second end of the vibration damping bracket 220.

[0050] Understandably, the second end of the vibration damping bracket 220 is fixed to the outdoor unit of the air conditioner via the second vibration damping component 230. The second vibration damping component 230 can be made of materials with excellent elasticity and damping properties, such as rubber or silicone, which can form a flexible connection between the vibration damping bracket 220 and the outdoor unit of the air conditioner, further absorbing and buffering the vibration energy from the pipeline. Thus, by setting the second vibration damping component 230 on the vibration damping bracket 220, not only is the support stability of the entire vibration damping structure enhanced, but the vibration reduction and noise reduction effect is also effectively improved.

[0051] Optionally, the second damping component 230 can be a damping pad, a damping spring, or both.

[0052] For example, the second end of the vibration damping bracket 220 is pre-embedded with a vibration damping spring and fitted with vibration damping pads before being fixed to the casing of the outdoor unit of the air conditioner. Thus, the vibration damping bracket 220 can effectively reduce the noise caused by refrigerant impacting the pipes.

[0053] In this embodiment, the fixing ring 110 is a clamp, the first damping component 120 is a damping rubber block set on the inner wall of the clamp, and the damping rubber block has an installation hole for installing pipelines inside; the damping bracket 220 is made of high carbon steel to increase the pipeline support strength.

[0054] Understandably, when the air conditioning system generates noise, the damping rubber blocks inside the clamp will initially weaken the noise, and then the three-layer composite structure damping component 210 will further absorb the kinetic energy of sound vibration from the inside out; and the high-carbon steel damping bracket 220 provides strength guarantee for the first damping mechanism 100 and the damping component 210.

[0055] In one embodiment of this utility model, such as Figure 2 As shown, the vibration damping bracket 220 includes two first support arms 221 arranged opposite to each other. The first ends of the two first support arms 221 are connected to the fixing ring 110 and the vibration damping component 210. The second ends of the first support arms 221 are provided with second vibration damping components 230. The distance between the two support arms gradually increases from the first end to the second end.

[0056] For example, the vibration damping bracket 220 includes two first support arms 221 arranged horizontally opposite each other. The first support arms 221 are arranged vertically, and their upper ends are connected to the fixing ring 110 and the vibration damping component 210. The two first support arms 221 gradually open outwards towards the second end along the extension direction, so that the distance between them gradually increases from the upper end to the lower end, forming an inverted V-shaped structure with a gradually expanding opening. This design not only enhances the overall force distribution capacity of the vibration damping bracket 220 and improves the stability and load-bearing strength of the structure, but also effectively adapts to the layout requirements of the installation space and improves assembly flexibility. A second vibration damping component 230 is provided at the lower end of the first support arm 221 to form a flexible connection with the bottom of the air conditioner outdoor unit, thereby further absorbing vibration energy, reducing noise transmission, and enhancing the overall vibration damping effect and operational stability of the system.

[0057] Optionally, the two first support arms 221 are connected by an arc transition.

[0058] Understandably, the upper ends of the two first support arms 221 are connected by an arc structure, creating a continuous and smooth structural transition. This arc transition not only enhances the overall structural strength and rigidity of the vibration damping bracket 220, but also effectively reduces structural fatigue problems that may be caused by stress concentration, thereby enhancing the durability and stability of the bracket under long-term vibration conditions.

[0059] In one embodiment of this utility model, two first support arms 221 are connected to adjacent sidewalls by second support arms 222, which are arranged in parallel, thus forming a more stable and robust support structure. By providing the second support arms 222, not only is the connection strength and structural rigidity between the two first support arms 221 enhanced, but the stability and deformation resistance of the vibration damping bracket 220 under complex vibration loads are also effectively improved. It should be noted that the second support arms 222 also serve to assist in positioning and distribute force evenly, preventing the bracket from twisting or shifting due to external forces, further improving the reliability and service life of the entire vibration damping system.

[0060] For example, each first support arm 221 is connected to a second support arm 222. The second support arms 222 are arranged vertically and are arranged close to each other. The upper end of the second support arm 222 is connected to the upper part of the first support arm 221. The first support arm 221 and the second support arm 222 connected thereto form a triangular structure, which enhances the stability of the vibration damping bracket, thereby reducing pipeline noise and achieving a better sound experience.

[0061] It should be noted that the two first support arms 221 are connected by an arc transition at the end near the vibration damping component 210, so that the two first support arms 221 form an arched structure, and the first support arm 221 and the second support arm 222 connected to it form a triangular structure; in this way, the vibration damping bracket 220 adopts a combination of arched and triangular structures, which enhances the stability of the structure.

[0062] It should be noted that the lower end of the second support arm 222 is also connected to the second damping component 230.

[0063] It should be noted that the ends of the first support arm 221 and the second support arm 222 that are away from the vibration damping component 210 are coplanar, so as to facilitate installation with the outdoor unit of the air conditioner.

[0064] A second aspect of this utility model provides an air conditioning system, which includes a housing and a pipe vibration damping device provided in any of the above embodiments.

[0065] It should be noted that the refrigerant noise and pipe vibration noise generated by refrigerant flow will be transmitted to the indoor side through the connecting pipes, resulting in a poor user experience. Therefore, this embodiment includes a pipe vibration damping device installed on the outdoor side.

[0066] Specifically, pipeline vibration damping devices are used to effectively support and dampen refrigerant pipelines or other fluid pipelines in air conditioning systems. By installing the vibration damping devices inside the casing or on structures connected to the casing, the vibration and noise caused by compressor start-up and shutdown, fan vibration or other external factors during pipeline operation can be significantly reduced, thereby effectively reducing the vibration and noise generated during the operation of the air conditioning system and improving the user experience.

[0067] It should be noted that the pipeline vibration damping device in this embodiment is not only compact and easy to install, but also has good vibration damping performance and load-bearing capacity, and can adapt to a variety of complex working conditions, thereby improving the operational stability, safety and user comfort of the air conditioning system.

[0068] Optionally, since the refrigerant flow generates significant noise at pipe bends, a pipe vibration damping device can be installed at the pipe bend, thereby forming an installation space inside the fixing ring 110 that is compatible with the pipe bend, and the shape of the first damping member 120 and its mounting holes are also compatible with the pipe bend.

[0069] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
