Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction, and more specifically, particularly relates to an acoustic package for a compressor. Background Art

[0002] Compressor noise is the biggest source of noise in the HVAC industry. The principle of noise treatment is to consume the energy in the process of sound wave transmission through a porous material, usually named "sound-absorbing material", and at the same time use a material with a certain density to block the transmission of sound waves, usually named "sound insulation material". The commonly used compressor noise treatment solution in the industry is to wrap the plane structure of sound insulation cotton in multiple layers to achieve the effect of noise treatment, but this solution has the following shortcomings:

[0003] 1. In order to ensure the noise effect, equipment manufacturers usually use a three-component design, one to wrap the compressor housing, one to wrap the peripheral liquid seal, and the last one to cover the top, which requires 2-3 employees to operate;

[0004] 2. Because of the flat structure design, it can only surround the compressor, but the top of the compressor and the compressor feet cannot be well wrapped, which will cause serious sound leakage problems. Utility Model Content

[0005] In order to solve the above technical problems, the utility model provides a compressor acoustic package to solve the problem of processing the vibration noise of the compressor.

[0006] The purpose and effect of the compressor acoustic package of the utility model are achieved by the following specific technical means:

[0007] A compressor acoustic package: comprising a compressor side enclosure acoustic package, wherein a compressor foot wrapping structure is fixedly connected to the bottom of the compressor side enclosure acoustic package, a compressor top cover acoustic package is arranged on the top of the compressor side enclosure acoustic package, sound insulation layers are fixedly connected to the inner walls of the compressor side enclosure acoustic package, the compressor foot wrapping structure and the compressor top cover acoustic package, and sound absorbing layers are respectively fixedly connected to the inner walls of the sound insulation layers.

[0008] Furthermore, the compressor top cover acoustic package is provided with a plurality of connecting straps on the outside, and Velcro a is fixedly connected to the inner sides of the plurality of connecting straps, and Velcro b matching the plurality of connecting straps is fixedly connected to the outside of the compressor side surround acoustic package.

[0009] Furthermore, the compressor top cover acoustic package is provided with threaded holes in the same number as the plurality of connecting belts, and the plurality of connecting belts are respectively provided with two through holes, each of the through holes is provided with a screw, and one end of the screw extends into the interior of the threaded hole.

[0010] Furthermore, the Velcro a is a velvet surface made of fine and soft fibers, and the Velcro b is a harder burr surface with hooks.

[0011] Furthermore, the sound insulation layer is formed as a whole from a polyolefin resin material with a high elongation rate through extrusion and calendaring, and the sound absorption layer is formed as a whole from a felt formed by hot pressing of polyester fibers.

[0012] Furthermore, a compressor is provided inside the compressor side surround acoustic package, and a compressor foot is provided inside the compressor foot wrapping structure.

[0013] Furthermore, the compressor foot is arranged in a triangular structure, and the compressor foot wrapping structure is arranged in a shape and structure that matches the compressor foot as a whole.

[0014] Furthermore, the top edge of the compressor top cover acoustic package is designed with rounded corners, and the overlapping dimension L between the compressor top cover acoustic package and the compressor side surround acoustic package is 10-50 mm.

[0015] Compared with the prior art, the utility model has the following beneficial effects:

[0016] 1. In the utility model, the groove-type blister structure and the rounded corner design of the compressor top cover acoustic package enable the compressor top cover acoustic package to fit closely with the compressor side enclosure acoustic package to prevent the compressor top cover acoustic package from leaking from the gap. The groove blister structure design of the compressor foot wrapping structure enables the product to fit closely with the compressor foot, minimizing the acoustic leakage at the compressor foot position. The good sound tightness structural design enables the entire product to reduce one component compared with the traditional solution, thereby reducing the production cost.

[0017] In the utility model, Velcro a and Velcro b are used to install the compressor top cover acoustic package on the compressor side surround acoustic package. The installation is simple and quick, which is convenient for subsequent repair and maintenance of the compressor and reduces the labor cost. The replaceable Velcro a can avoid the problem of poor adhesion effect caused by aging of Velcro a or straightening of cilia.

[0018] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0028] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples.

[0029] Example:

[0030] As attached Figure 1 To Attachment Figure 7 As shown:

[0031] A compressor acoustic bag: comprising a compressor side surround acoustic bag 1, a compressor foot wrapping structure 11 is fixedly connected to the bottom of the compressor side surround acoustic bag 1, a compressor top cover acoustic bag 12 is arranged on the top of the compressor side surround acoustic bag 1, a sound insulation layer 13 is fixedly connected to the inner walls of the compressor side surround acoustic bag 1, the compressor foot wrapping structure 11 and the compressor top cover acoustic bag 12, and a sound absorption layer 14 is fixedly connected to the inner wall of the sound insulation layer 13, a compressor 3 is arranged inside the compressor side surround acoustic bag 1, a compressor foot 31 is arranged inside the compressor foot wrapping structure 11, the sound insulation layer 13 is formed by extrusion and calendaring of a high elongation polyolefin resin material as a whole, the sound absorption layer 14 is formed by hot-pressing polyester fiber as a whole, the compressor foot 31 is arranged in a triangular structure, and the compressor foot wrapping structure 11 is arranged in a shape and structure matching the compressor foot 31 as a whole.

[0032] When in use, the compressor side surround acoustic package 1 is put on the outside of the compressor 3, so that the compressor foot wrapping structure 11 wraps the compressor foot 31. The shape and structure design of the compressor foot wrapping structure 11 can make it fit with the compressor foot 31, reduce the sound leakage at the position of the compressor foot 31, and the two protruding bumps thereon leave a certain space, which can facilitate the installation and removal of the compressor foot wrapping structure 11, and then the compressor top cover acoustic package 12 is covered on the compressor side surround acoustic package 1, so as to form a space. The noise generated by the compressor 3 when working is propagated in the space. First, the noise passes through the sound absorbing layer 14. The felt formed by hot pressing of polyester fibers has more pores. When sound waves propagate, they penetrate into the pores of the material and are subjected to friction and viscous resistance of air molecules, as well as mechanical vibration of fine fibers, thereby converting sound energy into heat energy. This absorption can effectively absorb medium and high frequency sounds and reduce echoes and noise in the space. Part of the noise passes through the sound-absorbing layer 14 to the sound insulation layer 13. The sound insulation layer 13, which is formed by extrusion and calendaring of a high-elongation polyolefin resin material, has high elasticity and is not easy to break. It can adapt to different installation environments. Polyolefin itself has good waterproof properties and can effectively prevent moisture penetration.

[0033] Among them, the compressor top cover acoustic package 12 is provided with multiple connecting belts 2 on the outside, and the inner sides of the multiple connecting belts 2 are fixedly connected with Velcro a21, and the compressor side wall acoustic package 1 is fixedly connected with Velcro b22 in a number matching the multiple connecting belts 2 on the outside. The Velcro a21 is a velvet surface made of fine and soft fibers, and the Velcro b22 is a harder barbed surface with hooks. The top edge line of the compressor top cover acoustic package 12 is chamfered, and the overlapping size L of the compressor top cover acoustic package 12 and the compressor side wall acoustic package 1 is 10-50mm.

[0034] When installing the compressor top cover acoustic package 12, the compressor top cover acoustic package 12 is put on the top of the compressor side wall acoustic package 1. The rounded corner design inside the compressor top cover acoustic package 12 can squeeze the top of the compressor side wall acoustic package 1 when it is put on, making it more sealed to prevent sound leakage. Then, the Velcro a21 on the connecting belt 2 is glued to the Velcro b22, and the Velcro b22 is installed and fixed.

[0035] Among them, the compressor top cover acoustic package 12 is provided with threaded holes 23 of the same number as the plurality of connecting belts 2, and the plurality of connecting belts 2 are respectively provided with two through holes 24, each of which is provided with a screw 25, and one end of the screw 25 extends into the threaded hole 23.

[0036] During long-term use, the fibers on the fleece surface of the Velcro a21 will age or gradually straighten, which will reduce the fixing effect on the compressor top cover acoustic package 12. This will cause a gap to appear between the compressor top cover acoustic package 12 and the compressor side wall acoustic package 1. At this time, the Velcro a21 needs to be replaced. During replacement, unscrew the screws 25 used to fix the connecting belt 2 from the threaded holes 23, and replace it with a new connecting belt 2. Align the two through holes 24 of the new connecting belt 2 with the two threaded holes 23 of the corresponding installation area, and then screw the screws 25 through the through holes 24 into the threaded holes 23, so as to fix the new connecting belt 2, and thus replace the Velcro a21.

[0037] Specific usage and function of this embodiment: When in use, the compressor side wall acoustic bag 1 is put on the outside of the compressor 3, so that the compressor foot wrapping structure 11 wraps the compressor foot 31. The shape and structure design of the compressor foot wrapping structure 11 can make it fit with the compressor foot 31, thereby reducing the sound leakage at the position of the compressor foot 31. The two protruding bumps thereon leave a certain space, which can facilitate the installation and removal of the compressor foot wrapping structure 11, and then the compressor top cover acoustic bag 12 is covered on the compressor side wall acoustic bag 1, thereby forming a space. When installing the compressor top cover acoustic bag 12, the compressor top cover acoustic bag 12 is put on the top of the compressor side wall acoustic bag 1. The rounded corner design inside the compressor top cover acoustic bag 12 can squeeze the top of the compressor side wall acoustic bag 1 when it is put on, making it more sealed to prevent sound leakage. Subsequently, the Velcro a21 on the connecting belt 2 is glued to the Velcro b22, and then the Velcro b22 is installed and fixed. When the Velcro a21 needs to be replaced, the fixed The screw 25 used to fix the connecting belt 2 is unscrewed from the threaded hole 23, and a new connecting belt 2 is replaced. The two through holes 24 of the new connecting belt 2 are aligned with the two threaded holes 23 of the corresponding installation area, and then the screw 25 is screwed into the threaded hole 23 from the through hole 24 to fix the new connecting belt 2. In this way, the Velcro a21 is replaced. The noise generated by the compressor 3 when working is propagated in the space. First, the noise passes through the sound-absorbing layer 14. The felt formed by hot pressing of polyester fibers has more pores. When the sound waves propagate, they penetrate into the pores of the material and are subjected to friction and viscous resistance of air molecules, as well as mechanical vibration of the fine fibers, thereby converting sound energy into heat energy. This absorption can effectively absorb medium and high frequency sounds and reduce echoes and noise in the space. Part of the noise passes through the sound-absorbing layer 14 to the sound insulation layer 13. The sound insulation layer 13, which is formed by extrusion and calendering of high-elongation polyolefin resin material, has high elasticity and is not easy to break. It can adapt to different installation environments. Polyolefin itself has good waterproof properties and can effectively prevent moisture penetration.
