AI Technical Summary
The existing compressor noise treatment solutions have problems of serious top sound leakage and high cost, especially the blister molding process has high requirements on mold cost, material performance and production efficiency, which leads to the inability to promote it on a large scale.
A compressor acoustic package including a side circumference, a top cover and a plurality of connectors is designed, and sufficient contact between the top cover and the side circumference is achieved through notches and connectors, reducing gaps, and reducing noise leakage through a combination of sound absorbing and sound insulation layers.
It effectively reduces the sound leakage on the top of the compressor, while reducing material costs and production costs. Compared with traditional planar structures and blister structures, the cost is reduced by 3% and 20% respectively, but the noise reduction effect is only reduced by 1db, meeting the dual requirements of cost and noise in the HVAC industry.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of compressor noise processing equipment, in particular to a compressor acoustic package. Background Art
[0002] Compressor noise is the largest source of noise in the HVAC industry. The principle of noise treatment is to use a porous material to consume the energy in the sound wave transmission process (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").
[0003] The commonly used compressor noise treatment solutions in the industry are to use multi-layer wrapping of flat sound insulation cotton to achieve the effect of noise treatment, and to use blister molding structure design to achieve tight fitting wrapping of the compressor, but these two solutions have the following shortcomings: 1. Using a multi-layer flat structure wrapping solution, 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 outer liquid seal, and the last one to cover the top, which requires 2-3 employees to operate, but the cover part on the top of the compressor is just a simple cover, and there will be a large gap, resulting in serious sound leakage on the top of the compressor; 2. Using blister molding acoustic package structure design, the cover part forms a concave structure by opening a blister mold, which covers the top of the compressor well and achieves a sealing effect, but due to the blister molding process, the mold cost, the mechanical properties of the material, the low production efficiency and other factors, the cost is high and cannot be widely promoted and applied. Utility Model Content
[0004] The utility model aims to provide a compressor acoustic package with low cost and good noise reduction effect, which can reduce the sound leakage at the top of the compressor.
[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0006] A compressor acoustic package, comprising a side enclosure, a top cover and a plurality of first connecting members; the top cover is arranged at the upper end of the side enclosure, and a accommodating cavity matching the compressor is formed between the top cover and the side enclosure; the top cover comprises a first sound-absorbing layer and a first sound-insulating layer interconnected from the inside to the outside; the side enclosure comprises a second sound-absorbing layer and a second sound-insulating layer interconnected from the inside to the outside; when the top cover is arranged on the top of the compressor, the outer edge of the top cover forms a side edge protruding outward from the top of the compressor, and the side edge is provided with a plurality of inwardly concave and evenly spaced notches, and the number of the notches is consistent with the number of the first connecting members; one end of the first connecting member is fixedly connected to the top cover, and the other end of the first connecting member fits the notch and is detachably connected to the side enclosure.
[0007] As a preferred solution of the utility model, the side enclosure is an expandable cylindrical structure, and both sides of the side enclosure after being expanded are provided with a joint portion, and the joint portions on both sides are detachably connected via a second connecting piece.
[0008] As a preferred solution of the present invention, the first connecting member is attached to the side circumference via a first Velcro.
[0009] As a preferred embodiment of the present invention, the first Velcro includes a first fleece surface and a first hook surface, the first fleece surface is arranged on the upper surface of the side circumference, the first hook surface is fixedly connected to the portion of the first connecting piece corresponding to the first fleece surface, and the first hook surface can fit with the first fleece surface.

The outer edge of the top cover forms a side edge protruding outward from the top of the compressor, and the side edge is provided with a plurality of inwardly concave notches arranged at even intervals. The first connecting member can fit the notches and connect with the side enclosure through the first connecting member, so that the top cover and the side enclosure can be fully in contact, thereby effectively reducing the gap between the top cover and the side enclosure, and reducing the sound leakage at the top of the compressor; at the same time, since the side edge is the part of the first sound insulation layer exposed to the first sound absorbing layer, the connection structure of the top cover and the side enclosure can also reduce the material size requirements of the first sound absorbing layer during the production process, thereby effectively reducing the material cost and improving the noise reduction effect. Compared with the traditional plane structure, the utility model reduces the material cost by 3%; compared with the blister structure, the utility model reduces the comprehensive cost by 20%, but the noise reduction effect is reduced by 1db compared with the traditional plane structure, which can meet the current HVAC industry's dual requirements for cost and noise.
