Embodiment 1

[0038] figure 1 A schematic structural diagram of Embodiment 1 of the sound-absorbing structure according to the present invention is shown. like figure 1 As shown, this embodiment provides a sound-absorbing structure, comprising: a first panel 10 , a second panel 20 and a sound-absorbing layer, wherein the first panel 10 is provided with a sound-absorbing hole 11 , and the second panel 20 is provided on the first panel 10 outside. A sound-absorbing cavity is formed between the first panel 10 and the second panel 20, and the sound-absorbing layer is arranged in the sound-absorbing cavity.

[0039] By applying the technical solution of the present invention, when the sound source is on the side of the first panel of the sound-absorbing structure away from the second panel, the sound wave enters the sound-absorbing cavity formed between the first panel and the second panel through the sound-absorbing hole. The sound-absorbing layer is arranged in the sound-absorbing cavity, w...

Embodiment 2

[0051] Figure 5 A schematic diagram showing the arrangement of the muffler hole group in the second embodiment of the muffler structure according to the present invention. Figure 5 As shown in the second embodiment, the shape of the muffler hole group is improved, and the muffler hole group is V-shaped. The muffler hole group is V-shaped along the direction of sound wave transmission, which can make the sound wave enter the muffler structure more evenly, and increase the muffler effect of the muffler structure.

[0052] The muffler hole groups arranged in different shapes will produce different effects in the working environment of different air volume and air flow rate. Setting the shape of the muffler hole group correspondingly according to the noise level and air flow rate can improve the muffler effect. For the different air volume and residual pressure of the unit, the structure and layout of the sound-absorbing foam board will have a certain impact on the sound-absorb...

Abstract

The present invention provides a sound-absorbing structure, a fan coil unit and a wind cabinet unit, wherein the sound-absorbing structure includes: a first panel, on which a sound-absorbing hole is arranged; a second panel, arranged on the outside of the first panel, and a second panel A sound-absorbing chamber is formed between the first panel and the second panel; the sound-absorbing layer is arranged in the sound-absorbing chamber. The technical scheme of the invention effectively solves the problem of relatively high unit noise in the prior art.

Description

technical field [0001] The invention relates to the field of fans, and in particular, to a noise reduction structure, a fan coil assembly and a fan cabinet unit. Background technique [0002] The horizontal cabinet fan coil unit is generally composed of filtration, surface cooling, and fan sections, and is a whole chassis. When designing the unit, it is necessary to first select the type according to the application environment of the unit, and then calculate the working environment and other factors. If the air volume of the type selection is large or the calculation is inaccurate, the residual pressure of the unit will be greater than the actual need, which will lead to the noise of the unit. . SUMMARY OF THE INVENTION [0003] The present invention aims to provide a noise reduction structure, a fan coil assembly and a fan cabinet unit, so as to solve the problem that the noise of the unit is relatively high in the prior art. [0004] In order to achieve the above obje...
