The vibration reduction scheme of the compressor of the heat pump air conditioning unit is to fix the compressor to the base plate by rubber bottom corners. Other components are connected to the compressor through copper pipes and are also fixed to the base plate by the bracket. The vibration of the compressor is reduced by the rubber bottom corners and then transmitted to the base plate.

[0004] However, the above vibration reduction schemes are not very effective at isolating low-frequency vibrations. Utility Model Content

[0005] To address the problem that existing vibration reduction solutions have poor vibration isolation effects for low-frequency vibrations, this utility model provides a vibration reduction structure and a heat pump unit.

[0006] On one hand, this utility model provides a vibration reduction structure, including: a first vibration damping member; a second vibration damping member; a vibration isolation plate, wherein the first vibration damping member and the second vibration damping member are respectively disposed on opposite sides of the vibration isolation plate, the first vibration damping member is used to connect to the compressor of a heat pump unit; a chassis, the chassis having a bottom plate, the vibration isolation plate being connected to the chassis and located above the bottom plate, the vibration isolation plate and the bottom plate forming a cavity, and at least a portion of the second vibration damping member being located within the cavity.

[0007] In the preferred embodiment of the above-mentioned vibration reduction structure, the first vibration damping member includes a first connecting part and a first vibration damping part. The first connecting part is used to connect the compressor and the vibration isolation plate, and the first vibration damping part is sleeved on the first connecting part.

[0008] In the preferred embodiment of the above-mentioned vibration damping structure, the first connecting part includes a connecting shaft and a fixing part. One end of the fixing part and the first vibration damping part are both sleeved on the connecting shaft. The first vibration damping part and the fixing part are respectively located on both sides of the connecting part of the compressor, and the fixing part is used to press the connecting part onto the first vibration damping part.

[0009] In the preferred embodiment of the above vibration reduction structure, the vibration isolation plate has a first mounting groove, and the first mounting groove has at least one mounting hole, which is connected to the first connecting part.

[0010] In the preferred embodiment of the above vibration reduction structure, the vibration isolation plate also has a second mounting groove, which is used to connect with other components of the heat pump unit.

[0011] In the preferred embodiment of the above-mentioned vibration reduction structure, the second vibration damping member includes a second connecting part and a second vibration damping part. One end of the second connecting part is connected to the bottom plate, and the other end passes through the vibration isolation plate. The second vibration damping part is sleeved on the second connecting part, and one end of the second vibration damping part contacts the bottom plate, while the other end extends between the vibration isolation plate and the second connecting part.

[0012] In the preferred embodiment of the above-mentioned vibration reduction structure, multiple second vibration damping elements are provided, and each second vibration damping element is spaced around the periphery of the vibration isolation plate, and the projection of each second vibration damping element toward the vibration isolation plate does not coincide with the projection of each first vibration damping element toward the vibration isolation plate.

[0013] In the preferred embodiment of the above vibration reduction structure, the vibration isolation plate has at least one clearance portion, which is disposed on the periphery of the vibration isolation plate.

[0014] In the preferred embodiment of the above vibration reduction structure, the chassis also has side plates, and the side ends of the vibration isolation plates are detachably connected to the side plates.

[0015] On the other hand, this application also provides a heat pump unit, including a compressor, a gas-liquid separator and a plate heat exchanger, wherein at least one of the compressor, the gas-liquid separator and the plate heat exchanger is disposed on the vibration damping structure in the above embodiment.

[0016] Those skilled in the art will understand that this utility model provides a vibration damping structure and a heat pump unit. The vibration damping structure comprises: a first vibration damping element; a second vibration damping element; a vibration isolation plate, with the first and second vibration damping elements respectively disposed on opposite sides of the vibration isolation plate. The first vibration damping element is used to connect to the compressor of the heat pump unit, and the vibration isolation plate also supports at least one other component of the heat pump unit; and a chassis with a base plate. The vibration isolation plate is connected to the chassis and located above the base plate, forming a cavity with the base plate.

A multi-stage vibration damping system is formed by the first vibration damping element, the second vibration damping element, and the cavity, improving the vibration damping effect. When the compressor vibrates, the vibration is attenuated in the first stage by the first vibration damping element, transmitting the vibration to the vibration isolation plate. A second stage of vibration attenuation occurs through the second vibration damping element below the vibration isolation plate and the cavity, further attenuating the vibration transmitted to the chassis and reducing overall vibration and radiated noise. Therefore, this application effectively reduces the vibration transmission of the compressor, reduces the vibration amplitude caused by resonance, and improves the vibration reduction effect by means of multi-stage vibration isolation.

[0027] First, those skilled in the art should understand that these embodiments are merely for explaining the technical principles of this utility model and are not intended to limit the scope of protection of this utility model. Those skilled in the art can make adjustments as needed to adapt to specific applications. For example, although the vibration damping structure of this utility model is described in conjunction with an air conditioning heat pump unit, this is not limiting; other devices with vibration damping requirements can be configured with the vibration damping structure of this utility model, such as heat pump water heaters and heat pump dryers.

[0028] Secondly, it should be noted that in the description of this utility model, the terms "inner" and "outer," etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. This is merely for the convenience of description and does not indicate or imply that the device or component must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation of this utility model.

[0029] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Taking an air conditioning heat pump unit as an example, the heat pump unit includes a compressor, a base plate, other components (such as a gas-liquid separator and a plate heat exchanger) and a bracket. The vibration reduction scheme of the compressor of the heat pump air conditioning unit is to fix the compressor to the base plate by rubber bottom corners. Other components are connected to the compressor through copper pipes and are also fixed to the base plate by the bracket. The vibration of the compressor is reduced by the rubber bottom corners and then transmitted to the base plate.

[0031] Specific vibration isolation methods include: one is to directly use three rubber base plates to fit onto the three bolts that fix the compressor for vibration reduction; the other is to add a thick plate or a cast iron plate of a certain weight under the compressor, and use rubber base plates to reduce vibration between the thick plate and the compressor, and between the bracket and the base plate. However, since only the compressor and some parts are on the thick plate, the load on the thick plate is relatively small, which is not conducive to vibration attenuation. Using thicker cast iron as a secondary vibration isolation plate requires a large space.

[0032] However, the aforementioned vibration reduction schemes are ineffective at isolating low-frequency vibrations. Specifically, existing single-stage vibration isolation technology cannot effectively isolate low-frequency structural vibrations, which are easily transmitted and generate low-frequency noise. Furthermore, the compressor uses a vibration isolation method connected to its components via copper pipes. Due to the fixed constraints, the compressor's vibration and swaying increase the vibration stress on the copper pipes, posing a risk of breakage. Existing compressor vibrations are transmitted through the suction and discharge copper pipes to the gas-liquid separator and plate heat exchanger, subsequently causing vibration of the base plate and generating radiated noise. The compressor's piping has a flexible connection at one end and a fixed connection at the other, resulting in significant relative movement between them. Repeated bending of the piping increases stress, thus reducing its service life.

[0033] This utility model provides a vibration damping structure and a heat pump unit. The vibration damping structure includes: a first vibration damping component; a second vibration damping component; a vibration isolation plate, wherein the first and second vibration damping components are respectively disposed on opposite sides of the vibration isolation plate, and the first vibration damping component is used to connect to the compressor of the heat pump unit; a chassis, the chassis having a bottom plate, the vibration isolation plate being connected to the chassis and located above the bottom plate, the vibration isolation plate and the bottom plate forming a cavity, and at least part of the second vibration damping component being located within the cavity. A multi-stage vibration damping system is formed by the first vibration damping component, the second vibration damping component, and the cavity, improving the vibration damping effect. When the compressor vibrates, the vibration is attenuated in the first stage by the first vibration damping component, transmitting the vibration to the vibration isolation plate, and then attenuated in the second stage by the second vibration damping component below the vibration isolation plate and the cavity, thereby further attenuating the vibration transmitted to the chassis and reducing overall vibration and radiated noise. Therefore, this application effectively reduces the vibration transmission of the compressor, reduces the vibration amplitude caused by resonance, and improves the vibration damping effect through multi-stage vibration isolation.

[0034] It should be noted that the vibration damping plate is also used to support at least one other component of the heat pump unit, namely...

[0035] It is understandable that the present invention improves the layout and installation method of the vibration reduction structure, so that the other components of the compressor unit that are mounted on the base plate are mounted on the vibration isolation plate. This can reduce the transmission of compressor vibration to the base plate, and also reduce the vibration of other components (such as gas-liquid separators and plate heat exchangers) connected to the compressor through copper pipes and their transmission to the base plate. Moreover, during the downward transmission of compressor vibration, the equipment mounted on the vibration isolation plate can provide mass, and the energy can be dissipated by the rubber base corners.

[0036] The following is combined Figures 1 to 4 The present invention describes the vibration reduction structure and heat pump unit of this utility model, as well as specific implementation methods or preferred technical solutions.

[0037] This utility model provides a vibration reduction structure, including: a first vibration damping member 100; a second vibration damping member 200; a vibration isolation plate 300, wherein the first vibration damping member 100 and the second vibration damping member 200 are respectively disposed on opposite sides of the vibration isolation plate 300, the first vibration damping member 100 is used to connect with the compressor 10 of the heat pump unit; a chassis 400, the chassis 400 having a bottom plate 410, the vibration isolation plate 300 being connected to the chassis 400 and located above the bottom plate 410, the vibration isolation plate 300 and the bottom plate 410 forming a cavity, at least a portion of the second vibration damping member 200 being located within the cavity.

[0038] For example, a heat pump unit includes at least one or a combination of any two of a compressor 10, a gas-liquid separator 20, and a plate heat exchanger 30. The operating principle in heating mode is as follows: the compressor 10, driven by a motor, compresses low-temperature, low-pressure refrigerant gas into high-temperature, high-pressure gas, which is then fed into the plate heat exchanger 30. The compressor 10 is connected to the gas-liquid separator 20 and the plate heat exchanger 30 via suction and discharge pipes. The compressor 10 can be installed at the bottom or side of the heat pump unit for easy connection to the gas-liquid separator 20 and the plate heat exchanger 30. The suction and discharge pipes can be copper pipes.

[0039] The vibration isolation plate 300 has a first mounting portion. The first damping member 100 and the second damping member 200 are respectively disposed on opposite sides of the vibration isolation plate 300. The first mounting portion and the first damping member 100 are located on the same side. The first damping member 100 is used to connect with the compressor 10 of the heat pump unit. The first mounting portion is used to connect with other components of the heat pump unit. Other components of the heat pump unit (such as at least one or a combination of gas-liquid separator 20 and plate heat exchanger 30) are disposed on the first mounting portion, wherein the first mounting portion can be a second mounting groove 320.

[0040] It is understood that, through the second mounting groove 320, at least one other component of the heat pump unit can be directly mounted on the vibration isolation plate 300. Moreover, the gas-liquid separator 20 and the plate heat exchanger 30 can also be suspended on the vibration isolation plate 300. For example, the connection between the gas-liquid separator 20 and the plate heat exchanger 30 is connected to the periphery of the second mounting groove 320. Both the gas-liquid separator 20 and the plate heat exchanger 30 are located above the second mounting groove 320, so that there is a gap between the gas-liquid separator 20 and the second mounting groove 320 or there is a gap between the gas-liquid separator 20 and the second mounting groove 320.

[0041] It is understandable that both the first damping component 100 and the second damping component 200 have damping devices. During assembly, the vibration isolation plate 300 is installed above the chassis 400 through the damping device of the second damping component 200, and the compressor 10 is installed above the vibration isolation plate 300 through the damping device of the first damping component 100. The vibration isolation plate 300 is suspended relative to the bottom plate of the chassis 400. The compressor 10 is formed by two layers of damping devices and the vibration isolation plate 300 to form a two-stage vibration reduction structure.

[0042] When the compressor 10 vibrates, the vibration is attenuated by the damping device of the first damping component 100 and then transmitted to the vibration isolation plate 300. It is understandable that the vibration of the vibration isolation plate 300 alone cannot effectively dissipate the vibration energy.

[0043] This application fixes components such as the gas-liquid separator 20 and plate heat exchanger 30, which were originally installed on the chassis 400, onto the vibration isolation plate 300. These components provide a certain mass to the vibration isolation plate 300, and the vibration damper of the second vibration damping component 200 below the vibration isolation plate 300 can provide a certain damping. In this way, the energy transmitted by the vibration of the compressor 10 will be further dissipated through the two-stage vibration isolation, and the vibration transmitted to the chassis 400 will be further attenuated, thereby reducing the vibration of the chassis 400 shell and reducing the radiated noise of the structure.

[0044] Moreover, the vibration isolation plate 300 is connected to the chassis 400 and is located above the base plate 410. The vibration isolation plate 300 and the base plate 410 form a cavity, and at least part of the second vibration damping member 200 is located in the cavity.

[0045] It should be noted that the vibration isolation plate 300 is also used to support at least one other component of the heat pump unit, namely, the vibration isolation plate 300 is also used to support at least one of the gas-liquid separator 20 and the plate heat exchanger 30 of the heat pump unit.

[0046] The compressor 10 in this application is suspended, and the gas-liquid separator 20 and plate heat exchanger 30 are also suspended on the vibration isolation plate 300. When the compressor 10 is running, the three can maintain the same phase vibration, so that both ends of the copper tube are flexibly connected. The relative movement between the components above the vibration isolation plate 300 and the compressor 10 will be reduced. In this way, the vibration and stress between the pipelines will be weakened to a certain extent, which helps to reduce the possibility of pipeline breakage due to shaking or vibration.

[0047] The vibration damping structure in this embodiment forms a multi-stage vibration damping system through the first damping member 100, the second damping member 200, and the isolation cavity, thereby improving the vibration damping effect. When the compressor 10 vibrates, the first damping member 100 performs a first-stage vibration attenuation, transmitting the vibration to the vibration isolation plate 300. The second damping member 200 and the isolation cavity below the vibration isolation plate 300 then perform a second-stage vibration attenuation, further reducing the vibration transmitted to the chassis 400 and weakening the overall vibration and radiated noise. Furthermore, at least one other component of the heat pump unit on the vibration isolation plate 300 (such as the gas-liquid separator 20 and the plate heat exchanger 30) increases the mass of the vibration isolation plate 300, thereby increasing the system inertia, attenuating the vibration transmitted by the compressor 10, and reducing the relative vibration between the compressor 10 and other components. Therefore, this application, through multi-stage vibration isolation, can effectively reduce the vibration transmission of the compressor 10, mitigate the vibration amplitude caused by resonance, and improve the vibration damping effect.

[0048] In the preferred embodiment of the above-mentioned vibration reduction structure, the first vibration damping member 100 includes a first connecting part 110 and a first vibration damping part 120. The first connecting part 110 is used to connect the compressor 10 and the vibration isolation plate 300, and the first vibration damping part 120 is sleeved on the first connecting part 110.

[0049] The first connecting part 110 is used to connect the compressor 10 and the vibration isolation plate 300, so that the compressor 10 is suspended above the vibration isolation plate 300, thereby reducing the vibration impact on the vibration isolation plate 300.

[0050] It should be noted that this application does not impose specific limitations on the shape, material, and thickness of the vibration isolation plate 300, which can be determined and adjusted according to the actual dimensions and installation. The vibration isolation plate 300 can be made of rubber or other components with spring damping function; this application does not impose any limitations on this.

[0051] In the preferred embodiment of the above-mentioned vibration damping structure, the first connecting part 110 includes a connecting shaft 111 and a fixing part 112. One end of the fixing part 112 and the first vibration damping part 120 are both sleeved on the connecting shaft 111. The first vibration damping part 120 and the fixing part 112 are respectively disposed on both sides of the connecting part of the compressor 10, and the fixing part 112 is used to press the connecting part onto the first vibration damping part 120.

[0052] One end of the fixing part 112 and the first vibration damping part 120 are sequentially sleeved on the connecting shaft 111, which is mounted on the vibration isolation plate 300. The fixing part 112 is used to press the compressor 10.

[0053] The connecting shaft 111 is vertically arranged, with its bottom end fixed in the first mounting groove 310 of the vibration isolation plate 300, and its top end penetrating the connecting part of the compressor 10, such as the mounting flange. The first damping part 120 can be an annular rubber body, sleeved in the middle of the connecting shaft 111, and compressed between the mounting flange of the compressor 10 and the vibration isolation plate 300.

[0054] This application does not limit the structure of the fixing part 112, which can be a locking nut. The fixing part 112 can also extend horizontally outward in the form of an L-shaped fold, with its horizontal section locked to the top of the connecting shaft 111 by a nut, pressing the flange of the compressor 10 onto the vibration damping part 120 to form an elastic clamping structure.

[0055] In the preferred embodiment of the above vibration reduction structure, the vibration isolation plate 300 has a first mounting groove 310, and the first mounting groove 310 has at least one mounting hole, which is connected to the first connecting part 110.

[0056] For example, the end of the first connecting part 110 is inserted into the mounting hole and threadedly connected to the mounting hole. The first mounting groove 310 has two preset mounting holes so as to make appropriate adjustments according to the structure and installation position of the compressor 10.

[0057] In the preferred embodiment of the above vibration reduction structure, the vibration isolation plate 300 also has a second mounting groove 320, which is used to connect with other components of the heat pump unit.

[0058] For example, the connection between the gas-liquid separator 20 and the plate heat exchanger 30 is connected to the periphery of the mounting groove. Both the gas-liquid separator 20 and the plate heat exchanger 30 are located above the mounting groove, so that a gap is formed between the gas-liquid separator 20 and the mounting groove or between the gas-liquid separator 20 and the mounting groove.

[0059] In the preferred embodiment of the above-mentioned vibration reduction structure, the second vibration damping member 200 includes a second connecting part 210 and a second vibration damping part 220. One end of the second connecting part 210 is connected to the base plate 410, and the other end passes through the vibration isolation plate 300. The second vibration damping part 220 is sleeved on the second connecting part 210, and one end of the second vibration damping part 220 contacts the base plate 410, and the other end extends between the vibration isolation plate 300 and the second connecting part 210.

[0060] The second vibration damping part 220 is sleeved on the second connecting part 210. The second connecting part 210 penetrates the vibration isolation plate 300. Part of the second vibration damping part 220 is located on the outer side of opposite sides of the vibration isolation plate 300. The end of the second vibration damping part 220 is connected to the chassis 400.

[0061] In addition, the second damping element 200 can also be a damping rubber bottom corner.

[0062] In the preferred technical solution of the above-mentioned vibration reduction structure, a plurality of second vibration damping members 200 are provided, and each second vibration damping member 200 is spaced around the periphery of the vibration isolation plate 300, and the projection of each second vibration damping member 200 toward the vibration isolation plate 300 does not coincide with the projection of each first vibration damping member 100 toward the vibration isolation plate 300.

[0063] For example, there are three first damping members 100, which are spaced apart. The three first damping members 100 are respectively connected to the connection part of the compressor 10 to jointly support the compressor 10. For example, the three first damping members 100 are spaced apart around the extension line of the center of the compressor 10, forming a triangular shape.

[0064] There are also multiple second damping elements 200, each of which is spaced around the periphery of the vibration isolation plate 300. For example, four second damping elements 200 are distributed at intervals along the four corners of the vibration isolation plate 300, and their projected positions do not overlap with the triangular projected areas of the three first damping elements 100.

[0065] In the preferred embodiment of the above-mentioned vibration reduction structure, the vibration isolation plate 300 has at least one clearance portion 330, which is disposed on the periphery of the vibration isolation plate 300.

[0066] The clearance portion 330 allows avoidance of other components on the chassis 400, resulting in a compact overall structure. The clearance portion 330 can be a recess, and this embodiment does not limit its application.

[0067] In the preferred embodiment of the above vibration reduction structure, the chassis 400 also has a side plate 420, and the side end of the vibration isolation plate 300 is detachably connected to the side plate 420.

[0068] For example, a side plate 420 is disposed on the periphery of the base plate 410, and a second connecting hole is provided on the side plate 420, through which bolts, screws or studs are passed to connect to the side end of the vibration isolation plate 300.

[0069] This application also provides a heat pump unit, including a compressor 10, a gas-liquid separator 20 and a plate heat exchanger 30, wherein at least one of the compressor 10, the gas-liquid separator 20 and the plate heat exchanger 30 is disposed on the vibration damping structure in the above embodiment.

[0070] In this application, components such as the gas-liquid separator 20 and plate heat exchanger 30, which were originally installed on the chassis 400, can be fixed on the vibration isolation plate 300. These components provide a certain mass to the vibration isolation plate 300, and the vibration damper of the second vibration damping component 200 below the vibration isolation plate 300 can provide a certain damping. In this way, the energy transmitted by the vibration of the compressor 10 will be further dissipated through the two-stage vibration isolation, and the vibration transmitted to the chassis 400 will be further attenuated, thereby reducing the vibration of the chassis 400 shell and reducing the radiated noise of the structure.

[0071] In the heat pump unit, the compressor 10 is mounted on the vibration isolation plate 300 at 120-degree intervals via three first vibration damping components 100. The gas-liquid separator 20 and the plate heat exchanger 30 are suspended and fixed via the second mounting groove 320. The second vibration damping component 200 of the chassis 400 supports the vibration isolation plate 300 to form a double-layer vibration damping system: after the vibration of the compressor 10 is attenuated by the first vibration damping component 100, the remaining energy is transferred to the vibration isolation plate 300, and then attenuated again by the second vibration damping component 200 and the isolation cavity before being transferred to the chassis 400; the added mass (gas-liquid separator 20 and plate heat exchanger 30) increases the system inertia, allowing the vibration energy to be further dissipated under the damping action of the second-stage vibration damping component 200. The gas-liquid separator 20 and the plate heat exchanger 30 vibrate in phase with the compressor 10, reducing the displacement difference between the two ends of the connecting copper pipe and decreasing the amplitude of alternating stress, which can effectively suppress pipeline fatigue fracture. In addition, the compressor 10 has relatively little shaking, which reduces the risk of it breaking during transportation.

[0072] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
