[0002] The refrigeration unit includes a water chiller-type refrigeration air conditioner. During operation, the water chiller requires ventilation and heat exchange to carry the heat generated by the IT equipment in the data center to the outside through the water medium for heat dissipation.

[0003] For example, existing water chiller equipment and sound insulation and noise reduction devices, publication number CN220817958U, include a frame and a sound insulation body. The sound insulation body is installed on the frame and, together with the frame, defines an accommodating space. The sound insulation body includes: several sound insulation panels, which are respectively fixed to the frame and interconnected to form a sound insulation wall. The sound insulation wall has at least one air inlet and at least one air outlet; and at least two ventilation silencers, which are respectively installed on the at least one air inlet and the at least one air outlet. The sound insulation body includes several sound insulation panels, air ducts, at least two ventilation silencers, and at least one sound insulation maintenance door. The sound insulation panels are respectively fixed to the support to form a sound insulation wall, isolating the cuboid frame defined by the frame from the outside world, thus playing a sound insulation role. The air ducts, ventilation silencers, and sound insulation maintenance door are respectively installed on the sound insulation wall.

[0004] However, after long-term operation of the ventilation silencer, the dust accumulation of the sound insulation cotton in the silencer unit varies. Some of the sound insulation cotton may have serious dust accumulation, and it is necessary to remove and clean the sound insulation cotton with serious dust accumulation. However, this device is not convenient for cleaning the sound insulation cotton. Utility Model Content

[0005] The purpose of this utility model is to solve the problems existing in the prior art and to propose a ventilation, sound insulation, noise reduction and silencing system for refrigeration units.

[0012] Preferably, one side of the inner side of the annular box is filled with sound-insulating cotton, and the two ends of the sound-insulating cotton are disposed between the threaded ring and the locking ring.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, the positioning sub-shaft and the positioning mother shaft are fixed by locking bolts, and the stepped limiting sub-plate and the mother plate are connected by inserts and slots.

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] like Figure 1-4 As shown, a ventilation, sound insulation, noise reduction system for a refrigeration unit includes a sound insulation body 1. The sound insulation body 1 includes a sound insulation panel 2 and several circular ventilation silencers 3. The sound insulation panel 2 has an opening 13. Several stepped limiting mother plates 8 arranged in a ring array are embedded and fixedly connected to the side of the opening 13. One end of the stepped limiting mother plates 8 is located inside the sound insulation body 1 and converges to a point, and is fixedly connected to a positioning mother shaft 11 coaxially arranged with one of the ventilation silencers 3. The other end is located outside the sound insulation body 1 and has several stepped limiting sub-plates 5 arranged in a ring array on one side. One end of the stepped limiting sub-plates 5 converges to a point and is fixedly connected to a positioning sub-shaft 12 opposite to the positioning mother shaft 11. The ventilation silencers 3 are located inside the stepped limiting sub-plates 5 and the stepped limiting mother plates 8. The ventilation silencers 3 include several coaxially arranged and slidably connected annular boxes 16.

[0024] In this technical solution, a multi-layered stepped limiting mother plate 8 and a stepped limiting daughter plate 5 are formed to limit the circular ventilation silencer 3. Specifically, several stepped limiting mother plates 8 are embedded in the side of the opening 13, and the multi-layered annular box 16 enters the interior of the stepped limiting mother plate 8 through the other end of the stepped limiting mother plate 8. The outermost annular box 16 abuts against the inner side of the opening 13, and the two can be sealed by filling with a sealing gasket.

[0025] The adjacent sides of two adjacent annular boxes 16 are slidably connected, and the innermost annular box 16 is sleeved with the positioning mother shaft 11 and the positioning daughter shaft 12, and the adjacent sides of the two are slidably connected.

[0026] Then, the other ends of several stepped limiting sub-plates 5 are positioned opposite to the other ends of several stepped limiting mother plates 8. By fixing the positioning sub-shaft 12 and the positioning mother shaft 11, the several stepped limiting sub-plates 5 and the several stepped limiting mother plates 8 are fixed, thereby confining the multi-layer annular box 16 inside them. When a blockage is found in a certain part of the ventilation silencer 3, by setting several annular boxes 16 and disassembling the positioning sub-shaft 12 and the positioning mother shaft 11, the blocked annular box 16 can be pulled out separately, thereby achieving the effect of convenient maintenance.

[0027] like Figure 2 and Figure 3 As shown, a locking bolt 7 passes through the positioning sub-shaft 12, and the locking bolt 7 is threadedly connected to the positioning female shaft 11. A slot 10 is opened at the other end of several stepped limiting sub-plates 5, and a plug block 9 that is inserted into the slot 10 is fixedly connected at the other end of several stepped limiting female plates 8.

[0028] In this technical solution, by setting locking bolts 7, the positioning sub-shaft 12 can be fixed to the positioning mother shaft 11, and the slots 10 at the other end of the stepped limiting sub-plates 5 can be inserted into the inserts 9 at the other end of the stepped limiting mother plates 8, thereby strengthening the fixation.

[0029] like Figure 2 As shown, several layers of annular boxes 16 are distributed in a stepped concave shape along the outline of the stepped limiting sub-plate 5 and the stepped limiting mother plate 8, and annular ventilation panels 4 are provided on both sides of the annular boxes 16.

[0030] In this technical solution, by setting multiple layers of annular boxes 16 with concave distribution, it is conducive to air inflow. By setting annular ventilation enclosure 4, air enters the annular box 16 through the annular ventilation enclosure 4. The annular ventilation enclosure 4 is limited by several stepped limiting mother plates 8 or several stepped limiting daughter plates 5, thereby embedding the annular ventilation enclosure 4 at both ends of the annular box 16.

[0031] like Figure 4As shown, threaded rings 15 are fixedly connected to both sides inside the annular box 16, and locking rings 14 are threadedly connected to the inner side of the threaded rings 15. Sound insulation cotton 6 is filled on one side of the inner side of the annular box 16, and the two ends of the sound insulation cotton 6 are set between the threaded rings 15 and the locking rings 14.

[0032] In this technical solution, by setting the threaded ring 15 and the locking ring 14, after the annular ventilation panel 4 is removed, the locking ring 14 is rotated to unscrew the locking ring 14 from the threaded ring 15. At this time, the sound insulation cotton 6 can be directly pulled out, which is convenient for cleaning or replacing the sound insulation cotton 6.

[0033] Working principle: During installation, the multi-layer ring box 16 is inserted through the other end of the stepped limiting mother plate 8. The outermost ring box abuts against the inside of the opening, and adjacent ring boxes are slidably connected. The innermost ring box 16 is slidably fitted along the positioning mother shaft 11. Then, the other end of the stepped limiting sub-plate 5 is aligned with the other end of the stepped limiting mother plate 8, and the insertion block 9 is inserted into the slot 10 for initial positioning. Then, the locking bolt 7 is threaded through the positioning sub-shaft 12 and connected to the positioning mother shaft 11 to restrict the ring box 16 inside.

[0034] During ventilation, air flows into the annular box 16 through the annular ventilation enclosure 4. The multi-layered stepped concave structure guides the airflow. At the same time, the sound insulation cotton 6 inside the annular box 16 is fixed to the locking ring 14 by the threaded ring 15, achieving noise reduction. During maintenance, loosen the locking bolt 7, disassemble the positioning sub-shaft 12 and the mother shaft 11, and drive the stepped limiting sub-plate 5 and the stepped limiting mother plate 8 to separate. The annular box 16 with heavy dust accumulation can be pulled out separately. After removing the annular ventilation enclosure 4, rotate and unscrew the locking ring 14 to remove the sound insulation cotton 6 for cleaning or replacement.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the present utility model.
