Preferably, the plurality of partition plates are respectively connected to the side plates and extend from the inner sides of the side plates, which are adjacent to the airflow channel 60, toward the airflow channel 60. In a preferred embodiment, the plurality of partition plates have a plurality of muffling chambers therebetween, and the plurality of muffling chambers are independent from each other and are not communicated with each other, so that the air flowing through the air flow channel 60 enters the muffling chambers independent from each other, and resonates and muffles in the muffling chambers.

The following description of the embodiments will be made with reference to the accompanying drawings, which illustrate embodiments of the present invention.
With continued reference to fig. 2 to 4, in the present embodiment, a plurality of first partition plates 22 are disposed inside the first side plate 21, a first muffling cavity 23 is disposed between any adjacent two first partition plates 22 in the plurality of first partition plates 22, and the first muffling cavity 23 is used for muffling airflow noise of the airflow, wherein the first muffling cavity 23 can be regarded as a cavity between two adjacent first partition plates 22. A plurality of second partition boards 25 are arranged on the inner side of the second side board 24, a second muffling cavity 26 is arranged between any two adjacent second partition boards 25 in the plurality of second partition boards 25, the second muffling cavity 26 is used for muffling airflow noise of airflow, wherein the inner side of the second side board 24 is opposite to the inner side of the first side board 21, and the second muffling cavity 26 can be regarded as a cavity between two adjacent second partition boards 25. The plurality of first partitions 22 have different heights such that the plurality of first muffling chambers 23 between the plurality of first partitions 22 have different heights; the plurality of second partitions 25 have different heights so that the plurality of second muffling chambers 26 between the plurality of second partitions 25 have different heights. The first muffling cavities 23 and the second muffling cavities 26 are respectively used for muffling airflow noises at multiple frequencies. In a preferred embodiment, any one first partition 22 of the plurality of first partitions 22 is simultaneously connected to the first side plate 21, the third side plate 211 and the fourth side plate 212, so that the plurality of first muffling cavities 23 between the plurality of first partitions 22 are independent from each other and are not communicated with each other, and when the airflow enters the plurality of independent first muffling cavities 23 from the airflow channel 60, resonance occurs to eliminate or reduce airflow noise; any one of the second partition boards 25 is connected to the second side board 24, the third side board 211 and the fourth side board 212 at the same time, so that the second muffling cavities 26 between the second partition boards 25 are independent and not communicated with each other, and after the airflow enters the independent second muffling cavities 26 from the airflow channel 60, resonance occurs to eliminate or reduce the airflow noise. In other words, in the above-described preferred embodiment, the plurality of first muffling chambers 23 are independent of each other, and the plurality of second muffling chambers 24 are independent of each other.
Further, with the center line C of the airflow channel 60 as a symmetry axis, the plurality of first partition plates 22 located on one side of the center line C are arranged to form a first arrangement pattern, the plurality of second partition plates 25 located on the other side opposite to the center line C are arranged to form a second arrangement pattern, and the first arrangement pattern and the second arrangement pattern are arranged in an axisymmetric manner. Since the first arrangement pattern and the second arrangement pattern are axisymmetrically arranged, the effect of eliminating airflow noise will be described below by taking the first partition plates 22 and the first muffling chambers 23 in the first arrangement pattern as an example.
Referring to fig. 4, the entire airflow channel 60 of the air duct 20 is sequentially divided into a first section 201, a second section 202 and a third section 203, the first section 201 is close to the air inlet of the airflow channel 60, the third section 203 is close to the air outlet of the airflow channel 60, the second section 202 is located between the first section 201 and the third section 203, wherein the first partitions 22 located in the first section 201, the second section 202 and the third section 203 may have different heights. Specifically, in the first section 201, the heights of the plurality of first partition plates 22 gradually increase from the air inlet toward the air outlet; in the second section 202, the plurality of first partitions 22 have a similar height to each other; in the third section 203, the heights of the first partition boards 22 gradually decrease and then gradually increase toward the air outlet. The heights of the first partition plates 22 in the first section 201 are gradually increased, and it can be considered that the first section 201 forms a necking (or converging) structure through the height change of the first partition plates 22 along the inflow direction of the airflow, and the design of the necking structure enables the first section 201 to concentrate more airflow into the airflow channel 60 to increase the inflow of the airflow; after the airflow passes through the second section 202, since the heights of the side plates 30 in the third section 203 gradually decrease and then gradually increase toward the air outlet side, the third section 203 can be regarded as a flaring structure formed by the height change of the first partition plates 22 along the outflow direction of the airflow, and the flaring structure is designed, so that the third section 203 has a larger airflow outflow capacity, more airflow is blown to the vicinity of the compressor 30 in a directional manner, the heat exchange of the compressor 30 is improved, the heat dissipation efficiency of the compressor assembly 100 is improved, and the energy consumption of the refrigerator is reduced.
Further, in the first section 201, the second section 202 and the third section 203, a first muffling chamber 23 is provided between any adjacent first partition plates 22, and the first muffling chamber 23 is used for muffling airflow noise of airflow passing through the first to third sections. Wherein each first muffling chamber 23 can muffle airflow noise of a corresponding frequency.
According to a calculation formula:
where n =1,2,3,4,5 … …, typically n = 1; c is the speed of sound propagation in air; l is the height of the corresponding first muffling chamber 23; the height L of the first muffling chamber 23 can be adjusted to eliminate the airflow noise of the corresponding frequency. The height L of the first muffling chamber 23 is the average of the sum of the heights L1, L2 of the two first partition plates 22 disposed on both sides of the first muffling chamber 23, that is, L = (L1+ L2)/2. In some embodiments of the present invention, when the heights of the first partition plates 22 on both sides of the first muffling chamber 23 are the same, the height L of the first muffling chamber 23 is equal to the height of the first partition plate 22.
It should be noted that, the present invention implements noise reduction processing on airflow noise of different frequencies by adjusting the height L of the first muffling cavity 23, and since the height L of the first muffling cavity 23 substantially depends on the height of the first partition plate 22 on both sides of the first muffling cavity 23, the present invention substantially enables the first muffling cavities 23 of a plurality of different heights to perform noise reduction processing on airflow noise of a plurality of different frequencies when the first muffling cavities 23 of a plurality of different heights are formed in the airflow channel 60 by adjusting the height of the first partition plate 22. That is, the first muffling cavities 23 with different heights between the first partition plates 22 with different heights in the air duct 20 are used to eliminate or reduce airflow noise with different frequencies, so as to achieve the effect of broadband noise reduction of the air duct 20.
Experiments prove that when the air duct 20 is arranged between the compressor 30 and the fan 10 of the compressor assembly 100, the first muffling cavities 23 and the second muffling cavities 26 with different heights formed by the first partition plates 22 and the second partition plates 25 respectively reduce the airflow noise of the airflow flowing through the airflow channel 60 by 2-3 decibels, wherein the frequency range of the airflow noise flowing through the airflow channel 60 is 89-11220 Hz.
In this embodiment, the side plates and the partition plates in the air duct 20 are integrally formed, for example, by injection molding. Furthermore, a plurality of silencing cavities among the plurality of partition plates can be filled with sound-absorbing materials, and the sound-absorbing materials can effectively improve the sound-absorbing effect. The sound absorption material is preferably foam plastic, urea-formaldehyde foam plastic, industrial felt or foam glass, and the like. The sound absorbing material may be formed on the side surfaces of the plurality of partitions and/or the inner sides of the side plates by means of adhesion, spraying, or the like.
