[0047] The accompanying drawings illustrate specific embodiments of this application, which will be described in more detail below. These drawings and descriptions are not intended to limit the scope of the concept in any way, but rather to illustrate the concept of this application to those skilled in the art through reference to particular embodiments. Detailed Implementation

[0048] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0049] The terms "first," "second," "third," "fourth," etc. (if present) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0050] In this application, the terms "exemplary" or "for example" are used to indicate examples, illustrations, or descriptions. Any embodiment or design described as "exemplary" or "for example" in this application should not be construed as being more preferred or advantageous than other embodiments or designs. Specifically, the use of terms such as "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0051] Furthermore, the terms "set up," "connect," and "fix" should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral structure; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be an internal connection between two devices, components, or parts. Those skilled in the art can understand the specific meaning of the above terms in the embodiments of this disclosure according to the specific circumstances.

[0052] Unless otherwise stated, the term "multiple" means two or more.

[0053] As the background technology indicates, during the transportation of heat pump outdoor units, the long distances and potentially complex terrain can cause impacts to the equipment due to vehicle bumps, sudden braking, or improper loading and unloading. These physical impacts directly or indirectly translate into mechanical stress on the piping system, especially the enthalpy-increasing pipes with smaller diameters and relatively flexible materials. Long-term or frequent accumulation of minor damage can eventually lead to cracks or even breakage in the pipes at stress concentration areas.

[0054] During operation, the high-speed rotation of the compressor in the outdoor unit of a heat pump generates strong mechanical vibrations. These vibrations not only originate from the unbalanced operation of the compressor itself but can also be exacerbated by an unstable installation foundation or insufficient vibration damping measures. The enthalpy-increasing pipe, as a crucial channel connecting the compressor and other components, is directly exposed to these high-frequency vibrations. Without effective vibration isolation design, the pipe wall material is prone to fatigue damage under prolonged vibration, gradually weakening its structural strength until it breaks. Once the pipe breaks, it not only affects the normal heating efficiency of the heat pump system but may also cause refrigerant leakage.

[0055] Figure 1 This is a schematic diagram of the enthalpy-increasing tube in related technologies; Figure 2 This is a schematic diagram illustrating the simulation results of the enthalpy-increasing tube model in related technologies. Combined with... Figure 1 and Figure 2 As shown, the maximum stress in the enthalpy-increasing tube is approximately 172 MPa. Among them, Figure 2 Different shades of color on the surface of the enthalpy-increasing tube represent different levels of stress. Higher stress levels are more likely to occur at bends in the enthalpy-increasing tube and at the connection point between the tube and the economizer.

[0056] It is evident that the existing heat pump outdoor unit is prone to pipe structure breakage due to vibration during transportation and use, affecting the reliability and durability of the equipment.

[0057] To address the aforementioned issues, this application provides a piping structure and a heat pump outdoor unit.

[0058] The piping structure of the heat pump outdoor unit includes an enthalpy-increasing tube body; the enthalpy-increasing tube body includes an annular portion, the first end of the annular portion is connected to the first part of the enthalpy-increasing tube body, and the first part of the enthalpy-increasing tube body is used to connect to the compressor; the second end of the annular portion is connected to the second part of the enthalpy-increasing tube body, and the second part of the enthalpy-increasing tube body is used to connect to the economizer.

[0059] The annular portion increases the flexibility of the enthalpy-increasing tube, providing buffering and vibration absorption, allowing the pipeline some deformation space during vibration, thereby reducing stress concentration. The presence of the annular portion disperses and absorbs vibration energy during transmission, reducing damage to the pipeline and connections.

[0060] The second section is shorter than the first section, meaning the annular portion is positioned closer to the economizer. This allows vibrations to be more effectively buffered and absorbed during transmission, reducing the impact on the connection between the pipe and the economizer. This design also reduces stress concentration and lowers the risk of pipe breakage.

[0061] The technical solutions of this application and how they solve the aforementioned technical problems are described in detail below with specific embodiments. These specific embodiments may exist independently or in combination with each other. Identical or similar concepts or processes may not be repeated in some embodiments. The embodiments of this application will now be described with reference to the accompanying drawings.

[0062] Figure 3 This is a schematic diagram of the structure of the heat pump outdoor unit provided in an embodiment of this application; Figure 4 for Figure 3 A schematic diagram of the structure of the enthalpy-increasing tube body; Figure 5 for Figure 4 Enlarged view of part A in the middle.

[0063] Combination Figure 3 to Figure 5 As shown, one embodiment of this application provides a piping structure for a heat pump outdoor unit, including an enthalpy-increasing tube body 100.

[0064] Understandably, the outdoor unit of the heat pump has a chassis and a partition 400 mounted on the chassis. The compressor 200 is mounted on the chassis, the economizer 300 is mounted on the partition 400, and the enthalpy-increasing pipe body 100 connects the compressor 200 and the economizer 300.

[0065] In some embodiments, a first portion of the enthalpy-increasing tube body 100 is used to connect to the compressor 200; a second portion of the enthalpy-increasing tube body 100 is used to connect to the economizer 300.

[0066] Compressor 200 is one of the core components of the heat pump system, responsible for compressing the refrigerant and driving its circulation. By connecting the first part of the enthalpy-increasing pipe to compressor 200, the refrigerant can flow smoothly from compressor 200 into the enthalpy-increasing pipe, ensuring the refrigerant's flow path.

[0067] Economizer 300 is typically used to improve the efficiency of heat pump systems. By directly connecting the second part of the enthalpy-increasing tube body 100 to economizer 300, efficient refrigerant transfer and heat exchange can be achieved.

[0068] In some embodiments, the enthalpy-increasing tube body 100 includes an annular portion 140, the first end of the annular portion 140 being connected to a first portion of the enthalpy-increasing tube body 100, and the second end of the annular portion 140 being connected to a second portion of the enthalpy-increasing tube body 100.

[0069] The annular portion 140 increases the flexibility of the enthalpy-increasing tube body 100, providing a vibration buffering effect. This design allows the enthalpy-increasing tube body 100 to have a certain deformation space during vibration, which can effectively alleviate the vibration from the compressor 200, allowing the vibration to be more effectively buffered and absorbed during transmission, thereby reducing stress concentration and lowering the risk of breakage of the enthalpy-increasing tube body 100.

[0070] It should be noted that the projection of the annular portion 140 can form a ring within a plane.

[0071] For example, when the vibrations experienced by the enthalpy-increasing tube body 100 are mostly vertical, the aforementioned plane can be a horizontal plane, and the projection of the annular portion 140 in the horizontal plane can be arranged in a ring. By utilizing the shape characteristics of the annular portion 140, vertical vibrations can be better buffered and absorbed.

[0072] When the vibrations experienced by the enthalpy-increasing tube body 100 are mostly in a certain horizontal direction, the aforementioned plane can be a vertical plane, with the normal of the vertical plane parallel to the horizontal direction. The projection of the annular portion 140 in the vertical plane can form a ring. By utilizing the shape characteristics of the annular portion 140, the vibrations in the horizontal direction can be better buffered and absorbed.

[0073] In some embodiments, the length of the second part is less than the length of the first part.

[0074] Understandably, the length of the second part is less than the length of the first part, so that the annular portion 140 is positioned close to the economizer 300. This arrangement reduces the impact on the connection between the enthalpy-increasing tube body 100 and the economizer 300, reduces the possibility of vibration being transmitted to the economizer 300, and reduces damage to the pipeline and connection.

[0075] Specifically, the piping structure of the heat pump outdoor unit provided in this application embodiment provides additional flexibility and vibration buffering capacity by providing an annular portion 140 on the enthalpy-increasing tube body 100. This effectively alleviates and absorbs the vibration generated during the operation of the compressor 200. Especially at the connection between the enthalpy-increasing tube body 100 and the economizer 300, it can reduce the risk of stress concentration and breakage, and improve the reliability and durability of the piping.

[0076] Figure 8 This is a schematic diagram of the simulation results of the piping structure of the heat pump outdoor unit provided in an embodiment of this application. Combined with... Figure 4 and Figure 8 As shown, an annular portion 140 is provided on the enthalpy-increasing tube body 100, and the maximum stress of the enthalpy-increasing tube body 100 is approximately 155 MPa. Among these, Figure 8 Different shades of color on the surface of the enthalpy-increasing tube body 100 represent different stress levels.

[0077] Compared to related technologies where the enthalpy-increasing tube does not have an annular portion 140, the maximum stress value of the enthalpy-increasing tube body 100 is reduced. Therefore, the piping structure of the heat pump outdoor unit provided in this embodiment can effectively reduce local stress and lower the risk of pipe breakage.

[0078] It should be noted that the piping structure of the outdoor unit of the heat pump provided in this application embodiment may also include an intake pipe, an exhaust pipe, and other pipes subject to significant vibration. To reduce the vibration-induced breakage of these pipes, annular portions 140 may be provided on these pipes to increase the flexibility and vibration buffering capacity of the pipes. This can effectively mitigate and absorb vibrations generated during equipment transportation and operation, reduce the risk of stress concentration and breakage, and improve the reliability and durability of the piping.

[0079] Combination Figure 4 and Figure 5 As shown, in some embodiments, the enthalpy-increasing tube body 100 includes a first connecting section 110 and a second connecting section 120 connected to each other; the extension direction of the first connecting section 110 is consistent with the vertical direction; the extension direction of the second connecting section 120 is consistent with the horizontal direction, and one end of the second connecting section 120 away from the first connecting section 110 is connected to the annular portion 140.

[0080] Understandably, the first part of the enthalpy-increasing tube body 100 includes a first connecting section 110 and a second connecting section 120 connected together.

[0081] By dividing the enthalpy-increasing tube body 100 into two connecting sections, the direction and position of each section can be better controlled, thus providing greater flexibility in the design and installation process.

[0082] The first connecting section 110 is aligned with the vertical direction, allowing the pipeline to better adapt to the vertical layout inside the equipment. The vertical design effectively utilizes the natural force of gravity, reducing pipeline bending and stress concentration.

[0083] The horizontal extension of the second connection section 120 allows for more flexible piping arrangement within the equipment, facilitating connection with other horizontally arranged components (such as the economizer 300).

[0084] Combination Figure 4 and Figure 5 As shown, in some embodiments, the enthalpy-increasing tube body 100 further includes a third connecting section 130, the extension direction of the third connecting section 130 being parallel to the extension direction of the second connecting section 120; the third connecting section 130 is connected to the end of the annular portion 140 opposite to the second connecting section 120, and the end of the third connecting section 130 opposite to the annular portion 140 is used to connect to the economizer 300.

[0085] Understandably, the second part of the enthalpy-increasing tube body 100 includes the third connecting section 130.

[0086] By making the third connecting section 130 parallel to the second connecting section 120, the piping structure can be arranged more orderly inside the equipment.

[0087] By placing the annular portion 140 at the connection between the second connecting segment 120 and the third connecting segment 130, the vibration energy is effectively buffered during the transmission of the connecting segment when subjected to vibration, reducing the impact on the subsequent connecting segment, reducing the mutual interference between the second connecting segment 120 and the third connecting segment 130, and reducing the risk of stress concentration and fracture.

[0088] Combination Figure 4 and Figure 5 As shown, in some embodiments, the annular portion 140 includes a first rotating segment 141 and a second rotating segment 142 connected to each other; a first end of the first rotating segment 141 is connected to the end of the second connecting segment 120 opposite to the first connecting segment 110, and a second end of the first rotating segment 141 is connected to the first end of the second rotating segment 142; a second end of the second rotating segment 142 is connected to a third connecting segment 130.

[0089] By designing the annular portion 140 as two interconnected rotating sections, the flexibility and complexity of the enthalpy-increasing tube body 100 are increased. This allows for greater deformation space during vibration, thereby enhancing vibration buffering and absorption capabilities. This structure better adapts to vibration and stress variations, reduces stress concentration, and improves the durability of the enthalpy-increasing tube body 100.

[0090] The design of the first slewing section 141 provides a transition from the second connecting section 120 to the second slewing section 142, ensuring that vibrations can be gradually buffered and absorbed during transmission.

[0091] Specifically, by connecting the first rotating section 141 to the end of the second connecting section 120, the vibrational energy is first buffered by the first rotating section 141 when it enters the annular portion 140. The presence of the first rotating section 141 provides initial vibration absorption, and then the remaining vibration is transmitted to the second rotating section 142 for further buffering.

[0092] The design of the second slewing section 142 provides a transition from the annular section 140 to the third connecting section 130, ensuring that vibrations are adequately buffered before being transmitted to the third connecting section 130.

[0093] Specifically, by connecting the second rotating section 142 to the third connecting section 130, the vibration energy transmitted to the third connecting section 130 after being buffered by the two rotating sections is significantly reduced. This design ensures that the stress and vibration effects at the connection between the third connecting section 130 and the economizer 300 are minimized, improving the reliability of the connection.

[0094] In some embodiments, the first rotating segment 141 and the second rotating segment 142 are arranged opposite to each other, and the first rotating segment 141 and the second rotating segment 142 are wound into a spiral structure.

[0095] The relative arrangement of the first rotating section 141 and the second rotating section 142 enables the pipeline structure to achieve spatial symmetry and balance, avoiding excessive stress concentration in a certain direction or position, and helping to distribute vibration energy evenly.

[0096] Understandably, a spiral structure allows for more deformation space during vibration, providing a longer vibration buffer path within a limited space. This allows vibration energy to be gradually absorbed and dispersed during transmission, thereby reducing the impact on pipes and connections.

[0097] In some embodiments, the spiral structure is one of a circular spiral structure and a racetrack-shaped spiral structure.

[0098] Among them, the circular spiral structure can absorb vibration energy evenly in all directions, reducing stress concentration.

[0099] The racetrack-shaped helical structure provides a longer vibration damping path, making it suitable for use in relatively narrow spaces. The racetrack-shaped helix offers a longer deformation path within a limited width, thus more effectively absorbing and dispersing vibrational energy.

[0100] In some embodiments, the helical structure can also be a helical structure of other shapes. Regardless of the helical structure chosen, the pipeline can effectively absorb and disperse vibration energy by increasing flexibility and deformation path, reducing the risk of stress concentration and breakage.

[0101] In some embodiments, the first rotating section 141 and the second rotating section 142 can be a split structure, with the first rotating section 141 and the second rotating section 142 being formed in two separate steps and then connected together, which has the characteristics of being easy to process.

[0102] In some embodiments, the first rotating section 141 and the second rotating section 142 are integral structures.

[0103] By adopting an integrated structure that combines the first rotating section 141 and the second rotating section 142 into a continuous whole, potential weaknesses at the connection points are eliminated, improving the overall strength and reliability of the enthalpy-increasing tube body 100. This design reduces the number of connection points, thereby lowering the risk of leakage and breakage.

[0104] In some embodiments, there are multiple annular portions 140 connected sequentially; the first ends of the multiple annular portions 140 are connected to the second connecting segment 120, and the second ends of the multiple annular portions 140 are connected to the third connecting segment 130.

[0105] By incorporating multiple annular sections 140 and connecting them sequentially, the piping structure can provide a longer vibration buffer path and greater flexibility.

[0106] The series connection of multiple annular portions 140 increases the absorption path of vibration energy, allowing each annular portion 140 to gradually buffer and disperse vibration. This arrangement reduces the stress borne by a single annular portion 140 and improves the overall vibration management capability.

[0107] Specifically, by connecting the first ends of the multiple annular sections 140 to the second connecting section 120, vibration energy begins to be buffered as it enters the annular sections 140. After being gradually absorbed by the multiple annular sections 140, the remaining vibration energy is significantly reduced by the time it is transmitted to the third connecting section 130, which helps to minimize its impact before the vibration is transmitted to the economizer 300, reducing the risk of stress concentration and breakage of the enthalpy-increasing tube body 100.

[0108] Combination Figure 3 As shown, another aspect of this application provides a heat pump outdoor unit, including an economizer 300 and the piping structure of the heat pump outdoor unit provided in any of the above embodiments; the piping structure includes an enthalpy-increasing tube body 100, and the economizer 300 is connected to the enthalpy-increasing tube body 100.

[0109] The piping structure of the heat pump outdoor unit has been described in detail in the above embodiments and will not be repeated here.

[0110] In some embodiments, a partition 400 is also included, to which the economizer 300 is movably mounted.

[0111] Figure 6 for Figure 3 A schematic diagram of the middle partition. (Combined with...) Figure 6 As shown, a support base 420 is installed on the partition plate 400. The support base 420 has a support part 421 extending into the interior of the heat pump outdoor unit. The economizer 300 is disposed on the support part 421, and the support part 421 can provide support for the economizer 300.

[0112] Figure 7 This is a schematic diagram of the clamp structure in the outdoor unit of a heat pump provided in an embodiment of this application. (In conjunction with...) Figure 6 and Figure 7 As shown, in some embodiments, a clamp 410 may also be installed on the partition 400, and the economizer 300 is connected to the partition 400 through the clamp 410.

[0113] The clamp 410 is configured as a U-shaped clamp. The first end of the clamp 410 is provided with a clamp connector 411, which is detachably connected to the middle partition 400 through the clamp connector 411. The second end of the clamp 410 is provided with an installation part 412, which is detachably connected to the middle partition 400 through the installation part 412.

[0114] The clamp 410 and the partition 400 can be arranged to form a receiving area, the economizer 300 is set in the receiving area, and there is a gap between the economizer 300 and the inner wall of the receiving area.

[0115] The outer side of the economy unit 300 is covered with thermal insulation cotton, and the thermal insulation cotton is interference-fitted with the inner wall of the receiving area.

[0116] It should be noted that the amount of interference between the insulation and the inner wall of the containment area can be flexibly selected based on the specific material of the insulation.

[0117] The insulation cotton serves two purposes: it insulates the economizer 300 and it also provides resilience, allowing for a flexible connection between the economizer 300 and the clamp 410, thus giving the economizer 300 some room to move. This design allows the economizer 300 a degree of freedom when subjected to vibration, dispersing vibration energy and reducing the impact on the enthalpy-increasing tube.

[0118] In some embodiments, a snap-fit ​​groove 401 is provided on the partition plate 400, and the snap-fit ​​connector 411 of the clamp 410 can be inserted into the snap-fit ​​groove 401 and slide along the snap-fit ​​groove 401 so that the mounting part 412 of the clamp 410 is aligned with the screw hole provided on the partition plate 400.

[0119] When the mounting part 412 of the clamp 410 is aligned with the screw hole on the partition plate 400, the snap-fit ​​connector 411 slides to the snap-fit ​​section of the snap-fit ​​groove 401, and the snap-fit ​​connector 411 snaps into the snap-fit ​​section, thus achieving the connection between the first end of the clamp 410 and the partition plate 400. Then, by using a connector to connect the mounting part 412 and the partition plate 400 together, a fixed connection between the clamp 410 and the partition plate 400 can be achieved.

[0120] In some embodiments, both the first and second ends of the clamp 410 can be screwed to the partition plate 400; or, both the first and second ends of the clamp 410 can be snapped into the partition plate 400.

[0121] Specifically, by movably mounting the economizer 300 onto the partition plate 400, the movable mounting design allows the economizer 300 some room to move when subjected to external vibrations, thereby effectively absorbing and mitigating vibrations and reducing the risk of stress concentration on the enthalpy-increasing tube body 100. This configuration not only helps improve the stability and reliability of the equipment during transportation and operation, but also helps extend the service life of the pipeline structure and reduce maintenance costs and failure rates.

[0122] The technical solutions of this application have been described above with reference to the preferred embodiments shown in the accompanying drawings. However, it is readily understood by those skilled in the art that the scope of protection of this application is obviously not limited to these specific embodiments.
