[0001] The utility model relates to the technical field of compressors, and in particular to a noise reduction structure, a compressor device and a heat exchange device. Background Art

[0002] With the progress of society and the improvement of people's living standards, heat exchange equipment such as air conditioners and heat pumps are used more and more widely in life, increasing the comfort of people's lives. The air conditioner outdoor unit will generate noise during operation, and the noise mainly comes from the fan and compressor. The noise control of the fan is mainly achieved by improving its blade shape, while the main means of noise reduction for the compressor is to prevent the propagation of sound waves.

[0003] The current method for reducing noise of compressors is to install the compressor in a closed shell, and then set sound insulation cotton on the inner wall of the shell to isolate the noise generated by the compressor through the sound insulation cotton.

[0004] However, the shell resonance, pipe resonance and refrigerant flow noise generated by the operation of the compressor are the main noise sources of the refrigeration system and the biggest factor affecting the user's comfort. In the existing technology, the sound insulation cotton on the inner wall of the shell can only block the noise generated by the compressor once, and the noise will still be transmitted to the outside, reducing the user's experience. Utility Model Content

[0005] Therefore, the technical problem to be solved by the present invention is to overcome the defect in the prior art that the sound insulation cotton on the inner wall of the compressor casing can only block the noise generated by the compressor once, and the noise will still be transmitted to the outside, reducing the user's experience, thereby providing a noise reduction structure, a compressor device and a heat exchange equipment.

[0006] In order to solve the above technical problems, the utility model provides a noise reduction structure, comprising: a shell, wherein a first sound insulation layer is provided on the shell;

[0007] The inner shell is arranged inside the outer shell, a second sound insulation layer is arranged on the inner shell, the inner shell is a closed shell, and the interior of the inner shell has a storage space suitable for arranging a compressor and part of the system pipelines.

[0013] A compressor device comprises: a compressor and a noise reduction structure as described in any one of the above schemes, wherein the compressor and part of the system pipelines are arranged in the accommodating space of the inner shell in the noise reduction structure.

[0014] Optionally, a flexible noise reduction shell is provided on the outside of the compressor, and the flexible noise reduction shell fits around the compressor.

[0015] Optionally, the flexible noise reduction shell comprises: at least one noise reduction layer, the noise reduction layer comprises a flexible sound absorbing layer and a flexible sound insulating layer which are stacked, and the flexible sound absorbing layer is located on a side close to the compressor.

[0016] A heat exchange device comprises: a compressor device as described in any one of the above schemes.

[0017] The technical solution of the utility model has the following advantages:

[0018] 1. The noise reduction structure provided by the utility model arranges the compressor and the system pipeline in the accommodating space of the inner shell.

[0020] 3. In the compressor device provided by the utility model, the noise generated by the compressor and the system pipeline can be blocked by the flexible noise reduction shell, the second sound insulation layer and the first sound insulation layer. The noise transmitted to the outside is relatively small, and the user is not easy to hear the noise at this time, thereby improving the use comfort.

[0035] The noise reduction structure provided in this embodiment arranges the compressor 5 and the system pipeline 6 in the accommodating space of the inner shell 3. The noise generated by the compressor 5 and part of the system pipeline 6 is blocked twice by the second sound insulation layer 4 and the first sound insulation layer 2 successively, and the number of noise blocking times is increased, thereby reducing the noise transmitted to the outside and improving the user's comfort.

[0036] like Figure 1 , Figure 5As shown, in the noise reduction structure provided in this embodiment, a first elastic gasket 7 is provided on the inner bottom wall of the outer shell 1, and the inner shell 3 is arranged on the first elastic gasket 7. Specifically, the first elastic gasket 7 is bonded to the outer bottom wall of the inner shell 3, and the inner shell 3 and the outer shell 1 are connected by bolts.

The combination of the two has a better effect on the treatment of noise. In addition, as an alternative embodiment, the second sound insulation layer 4 can also be only the second porous sound absorbing layer 13, which absorbs the noise to improve the comfort of the user.

[0041] In addition, if Figures 1 to 4 As shown, this embodiment further provides a compressor device, including: a compressor 5 and the above-mentioned noise reduction structure, the compressor 5 and its system pipeline 6 are arranged in the accommodating space of the inner shell 3 in the noise reduction structure.

[0042] In the compressor device provided in this embodiment, the noise generated by the compressor 5 and the system pipeline 6 can be blocked by the flexible noise reduction shell 15, the second sound insulation layer 4 and the first sound insulation layer 2. The noise transmitted to the outside is relatively small, and the user is less likely to hear the noise at this time, thereby improving the comfort of use.

[0043] like Figure 1 , Figure 4As shown, in the compressor device provided in this embodiment, a flexible noise reduction shell 15 is arranged on the outside of the compressor 5, and the flexible noise reduction shell 15 is adhered to the periphery of the compressor 5. The flexible noise reduction shell 15 is adhered to the compressor 5 by bonding. The flexible noise reduction shell 15 is formed with a sealed space by the side panels, the bottom cover and the top cover. The flexible noise reduction shell 15 absorbs and blocks the noise generated by the operation of the compressor 5, and has a good use effect.

[0044] like Figure 1 , Figure 4 As shown, in the compressor device provided in this embodiment, the flexible noise reduction shell 15 includes: at least one noise reduction layer 16.

[0046] The noise reduction principle of the heat exchange equipment provided in this embodiment is as follows:

[0047] The noise generated during the operation of the compressor 5 and the system pipeline is first absorbed by the flexible sound-absorbing layer 17, and the part that is not absorbed is transmitted to the flexible sound insulation layer 18 for refracting, thereby further consuming and absorbing its energy. The remaining noise is transmitted outward to the inner shell 3, and then absorbed and refracted again by the second sound insulation layer 4. The remaining noise is transmitted outward to the outer shell 1, absorbed and refracted by the first sound insulation layer 2. By absorbing and refracting the noise multiple times, the noise is effectively eliminated, thereby improving the user comfort.
