Description

Technical Field

[0001] This application relates to the field of scroll compressor technology, and in particular to a silencer for a scroll compressor and a scroll compressor. Background Technology

[0002] Scroll compressors are widely used in refrigeration systems due to their large cooling capacity and low vibration. With technological advancements and increasingly fierce market competition, the required compressor speed has increased from 130 rpm to 160 rpm or even higher. Furthermore, the displacement of scroll compressors continues to rise, leading to a gradual increase in the discharge velocity within the compressor and consequently, increased compressor noise. Compressor noise is mainly categorized into aerodynamic noise, electromagnetic noise, and mechanical noise. As compressor speed and displacement increase, the refrigerant flow rate increases rapidly, and the gas discharge velocity increases. Especially with the intermittent discharge of scroll compressors, the discharge pulsation is exacerbated (the structure of scroll compressors, along with the intermittent discharge characteristics of the moving and fixed discs, causes the refrigerant gas to discharge intermittently, resulting in significant pressure pulsations within the compressor, causing the internal aerodynamic noise to gradually increase with increasing speed).

[0003] Traditional compressor layouts typically reduce exhaust flow velocity and thus compressor pulsation by designing a cavity volume at the top of the compressor. However, due to overall height limitations, the cavity volume cannot increase with rotational speed. Therefore, aerodynamic noise increases with both displacement and rotational speed, affecting the normal operation of the scroll compressor.

[0004] Therefore, it is necessary to design a silencer for scroll compressors to solve the above problems. Summary of the Invention

[0005] In view of this, in order to overcome the shortcomings of the prior art, the present invention provides a silencer for a scroll compressor and a scroll compressor, which effectively solves the problem that the aerodynamic noise of the existing scroll compressor will increase with the increase of displacement and speed.

[0006] According to a first aspect of the present invention, a silencing device for a scroll compressor is provided, wherein the silencing device for the scroll compressor includes a first silencing space and a second silencing space connected to each other by a first baffle. The first baffle includes a first guide portion disposed in the middle and a second guide portion disposed on the outer periphery. An exhaust hole is provided at the top of the second silencing space. The interior of the second silencing space is divided into a plurality of chambers by a partition. The first end of the chamber is close to the first guide portion, and the second guide portion is located at the second end of the chamber.

[0007] Preferably, with the upper surface of the first baffle as a plane, the size of the orthographic projection of the chamber onto the plane gradually decreases from the second end of the chamber to the first end of the chamber.

[0009] Preferably, the silencer for the scroll compressor further includes a flow guide shroud, which is disposed on the first flow guide portion and covers a portion of the first flow guide portion.

[0010] Preferably, the first flow guide includes a plurality of first flow guide holes, each of which is covered by a flow guide cover, and the opening directions of two adjacent flow guide covers are different.

[0016] The silencing device for scroll compressors according to the present invention enables secondary noise reduction of the gas through the cooperation of the first and second silencing spaces.

Using this silencing device significantly reduces the aerodynamic noise of the scroll compressor, especially at high speeds, solving the aerodynamic noise problem caused by gas pulsation.

Obviously, the described embodiments are only some embodiments of this application, and not all embodiments.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0032] According to a first aspect of the present invention, a silencer for a scroll compressor is provided, such as... Figures 1 to 7 As shown, the silencer for the scroll compressor is used in the scroll compressor to change the flow characteristics of the gas, so that the energy of the gas is dissipated and the pressure pulsation of the gas decreases, thereby effectively reducing the aerodynamic noise of the scroll compressor. The silencer for the scroll compressor includes a first silencer space 1 and a second silencer space 2.

[0033] In the following description, reference will be made to Figures 1 to 7 This section describes the detailed structure of the first silencing space 1 and the second silencing space 2 of the silencing device for the scroll compressor.

[0034] like Figure 1 , Figure 3 and Figure 5 As shown in the three figures, the structure of the muffler for the scroll compressor is viewed from the front, top, and bottom views, respectively. The figures reveal that the muffler includes a main body formed as a near-cylindrical structure and an annular outer edge for mounting and connection. The annular outer edge is located on the outer periphery of the bottom of the main body. The near-cylindrical structure of the main body facilitates gas flow and allows energy dissipation during gas flow.

[0035] Furthermore, such as Figure 2 As shown in the embodiment, the main body of the silencing device for the scroll compressor includes a first silencing space 1 and a second silencing space 2. The second silencing space 2 can be located above the first silencing space 1, where "above" refers to... Figure 2 In this way, the main body of the silencer for the scroll compressor can be formed into a structure with a double-layered silencer space, so as to facilitate the receiving of gas and reserve sufficient space for gas flow.

[0036] Furthermore, such as Figure 4 and Figure 5As shown, in the embodiment, the first silencing space 1 and the second silencing space 2 can be separated by a first baffle 3. The first baffle 3 can be formed into a disc-shaped structure. A first guide section 4 is provided in the middle of the disc-shaped structure, and a second guide section 5 is provided on the outer periphery of the disc-shaped structure. When the silencing device for the scroll compressor is in use, the first silencing space 1 is connected to the exhaust channel of the fixed plate 10 and can directly receive gas from the fixed plate 10. After the gas enters the first silencing space 1, it enters the second silencing space 2 through the first guide section 4 and the second guide section 5 of the first baffle 3. Compared to a single air intake, the gas entering the second silencing space 2 through two separate channels, the first guide section 4 and the second guide section 5, can be distributed more evenly. This allows the gas to be distributed more quickly and evenly in the second silencing space 2, thereby increasing the exhaust velocity and further dissipating the gas's energy, thus reducing aerodynamic noise. In addition, if a single air intake is used, the gas needs to move around the lower part of the first baffle 3 before it can be discharged. Therefore, passages are provided in the middle and outer periphery of the first baffle 3 to reduce exhaust resistance.

[0037] Furthermore, such as Figure 3 and Figure 4 As shown, in this embodiment, an exhaust port 6 is provided at the top of the second silencing space 2. After the gas enters the second silencing space 2, it is silencing by the silencing structure of the second silencing space 2 and then discharged from the exhaust port 6. The silencing structure of the second silencing space 2 may include multiple chambers. Specifically, the interior of the second silencing space 2 is divided into multiple chambers by partitions 7. Adjacent chambers are separated by partitions 7. To ensure that the gas has sufficient flow space, the partitions 7 do not completely isolate these chambers, but rather make these chambers open spaces, that is, the first end of the chamber is close to the first guide section 4, and the gas flowing out through the first guide section 4 can enter the interior of these chambers. In addition, the second guide section 5 is located at the second end of the chamber, and the gas flowing out through the second guide section 5 enters these chambers from the other end. The gas entering these chambers through the first guide section 4 or the second guide section 5 passes through these chambers, causing the energy of the gas to be dissipated, and then it is discharged from the exhaust port 6 located at the top.

[0038] This silencer for the scroll compressor, through the cooperation of the first silencer space 1 and the second silencer space 2, enables secondary noise reduction of the gas. The specially designed second silencer space 2 effectively dissipates the gas's energy, thereby reducing aerodynamic noise. Using this silencer significantly reduces the aerodynamic noise of the scroll compressor, especially at high speeds, effectively addressing aerodynamic noise caused by gas pulsation. It is suitable for large-displacement scroll compressors. Since the silencer does not alter the original structure of the scroll compressor, it can substantially reduce noise and improve the sound quality of the scroll compressor without compromising its energy efficiency, thus enhancing the product competitiveness of the scroll compressor.

[0039] Preferably, such as Figure 4 As shown, in this embodiment, with the upper surface of the first baffle 3 as a plane, the size of the chamber's orthographic projection on the plane gradually decreases from the second end to the first end. Referring to the above, the first baffle 3 is formed into a disc-shaped structure to correspond with the main body, which is formed into an approximately cylindrical structure. Figure 4 As shown in the cross-sectional view, multiple chambers are arranged sequentially along the circumference of the first baffle 3. Two adjacent chambers are separated by partitions 7. The first end of the partition 7 is located in the middle of the disc-shaped structure, and the second end is located on the outer periphery of the disc-shaped structure. There is a certain distance between the first ends of two adjacent partitions 7. This distance is used to receive gas from the first guide section 4, allowing the gas to flow into the interior of the chamber. Thus, each chamber, due to the separation by the partitions 7, can be formed into an approximately fan-shaped structure. The size of the second end of the fan-shaped structure (i.e., the end closer to the outer periphery of the disc-shaped structure) is larger than the size of the first end of the fan-shaped structure (i.e., the end closer to the middle of the disc-shaped structure). This fan-shaped structure results in a gradually decreasing cross-sectional area, allowing the gas to form vortices at the outlet position of the fan-shaped structure (the first end of the fan-shaped structure) for noise reduction (the airflow trajectory can be seen in...). Figure 7 ).

[0040] Preferably, such as Figure 2 and Figure 4 As shown, in this embodiment, the second silencing space 2 may further include a second baffle 201, which is disposed inside the second silencing space 2, dividing the second silencing space 2 into a first exhaust chamber 202 and a second exhaust chamber 203. The second baffle 201 may be perpendicular to the first baffle 3, dividing the second silencing space 2 into left and right parts. Further, both the first exhaust chamber 202 and the second exhaust chamber 203 may include multiple chambers, a first guide section 4, and a second guide section 5. In this way, gas can flow separately in the first exhaust chamber 202 and the second exhaust chamber 203, achieving more efficient silencing and adapting to high-speed operation of large-displacement scroll compressors.

[0041] Preferably, such as Figure 2 and Figure 4 As shown, in this embodiment, the silencer for the scroll compressor further includes a flow guide shroud 9, which is disposed on the first flow guide portion 4 and covers a portion of the first flow guide portion 4. The flow guide shroud 9 can be formed into a hemispherical structure and covers a portion of the first flow guide portion 4. The term "covering portion" can be understood as follows: in order to allow gas to flow out of the first flow guide portion 4 and to control the flow direction of the gas, the flow guide shroud 9 is installed on the first flow guide portion 4 so that the gas can only flow out from a specific direction.

[0042] Preferably, such as Figure 2 , Figure 4 and Figure 5 As shown, in this embodiment, the first flow guide 4 may include a plurality of first flow guide holes 401, each of which is covered with a flow guide shroud 9, and the opening directions of two adjacent flow guide shrouds 9 are different. To meet the requirement of sufficient flow, the number of first flow guide holes 401 is four in this embodiment, but more may be provided, which is not limited here. The four first flow guide holes 401 are arranged in pairs, respectively in the first exhaust chamber 202 and the second exhaust chamber 203. Each of the four first flow guide holes 401 is covered with a flow guide shroud 9, and the opening directions of the four flow guide shrouds 9 are different, so that the gas flowing out of these four flow guide shrouds 9 flows in different directions, which can make the gas move evenly to multiple chambers.

[0043] Preferably, such as Figure 2 As shown, in the embodiment, the second silencing space 2 includes a vertical direction (here, the vertical direction can be understood as...). Figure 2 The first receiving portion 204 and the second receiving portion 205 are arranged in a direction from bottom to top or from top to bottom. The flow guide 9 is disposed in the first receiving portion 204, and the baffle 7 is disposed in the second receiving portion 205. The first receiving portion 204 is disposed between the second receiving portion 205 and the first baffle 3. It can be understood that the upper end and the side end of the baffle 7 are integrally formed with the main body of the above-mentioned approximately cylindrical structure. The lower end of the baffle 7 is not connected to the first baffle 3, but forms a receiving space, namely the first receiving portion 204, between it and the first baffle 3. This can be used for the installation of the flow guide 9, and at the same time facilitates the flow of gas from the first flow guide portion 4 and the second flow guide portion 5 of the first baffle 3 to the corresponding position (see the gas flow path). Figure 6 ).

[0044] Preferably, such as Figure 4 and Figure 5As shown, in this embodiment, the second flow guiding section 5 includes at least two sets of flow guiding hole groups, each set including multiple second flow guiding holes 501. The at least two sets of flow guiding hole groups are sequentially arranged from the second end to the first end of the chamber, with the number of second flow guiding holes 501 in each set gradually decreasing from the second end to the first end. In this embodiment, the second flow guiding section 5 may include three sets of flow guiding hole groups: the set near the second end of the chamber includes five second flow guiding holes 501, the set near the first end of the chamber includes three second flow guiding holes 501, and the set between these two sets includes four second flow guiding holes 501. These three sequentially arranged sets of flow guiding holes allow gas to dissipate through eddy currents within the chamber, while simultaneously creating eddies at the opening of the chamber for noise reduction.

[0045] Preferably, such as Figure 4 As shown, in this embodiment, the multiple chambers may include multiple guide chambers 801 and at least one exhaust chamber 802. Since the second silencing space 2 is divided into a first exhaust chamber 202 and a second exhaust chamber 203 by the second baffle 201, both the first exhaust chamber 202 and the second exhaust chamber 203 may include multiple guide chambers 801 and at least one exhaust chamber 802, allowing for individual gas flow within these two exhaust chambers. Further, the multiple guide chambers 801 are separated from each other by partitions 7 and formed as guide sections. At least one exhaust chamber 802 is disposed at the end of the guide section, i.e., the exhaust chamber 802 needs to be disposed at the end of the guide chamber 801 for easy exhaust. An exhaust port 6 is disposed at the top of the exhaust chamber 802. Gas entering the multiple guide chambers 801 via the first guide port 401 and the second guide port 501 flows along the gas flow direction and finally reaches the exhaust chamber 802, and is discharged through the exhaust port 6 at the top of the exhaust chamber 802. In this embodiment, the exhaust chamber 802 of the first exhaust chamber 202 is disposed at... Figure 4 The upper part of the second exhaust chamber 203, the exhaust cavity 802 is located in the upper part of the middle part. Figure 4 The lower part, therefore see Figure 7 The gas flows in a roughly clockwise direction. Correspondingly, if the exhaust chamber 802 of the first exhaust chamber 202 is located in... Figure 4 The lower part of the middle, while the exhaust chamber 802 of the second exhaust chamber 203 is located in the lower part. Figure 4 If it is in the upper part, then the gas flows in a roughly counterclockwise direction.

[0046] Preferably, such as Figure 4 As shown, in this embodiment, the spacer 7 can be formed as a cuboid plate structure; however, it is not limited to this, and the spacer 7 can also be formed as an arc-shaped structure, for example, from... Figure 4 From the top-down view shown, the partition 7 is formed in an arc shape, which also allows gas to flow in the chamber, thereby forming a vortex at the opening for noise reduction.

[0047] The operation process of the silencer device for this scroll compressor is as follows: See Figure 6 and Figure 7 The scroll compressor is installed on the stationary plate 10 with a silencer. When the scroll compressor moves, the gas flows out from the exhaust channel of the stationary plate 10, passes through the first silencing space 1, the first guide hole 401 and the second guide hole 501 of the first baffle 3, and enters the second silencing space 2. Figure 6 As shown, the gas entering the second silencing space 2 through the first guide hole 401 enters the chamber from the first end, and the gas entering the second silencing space 2 through the second guide hole 501 enters the chamber from the second end; as Figure 7 As shown, after the gas enters the chamber, it moves along the flow path in the guide cavity 801 and is finally discharged from the exhaust cavity 802 through the exhaust hole 6 located at the top. Throughout the process, the gas undergoes vortex dissipation as it passes through multiple guide holes and multiple guide cavities 801, and forms vortices at the opening of the chamber to reduce noise, thereby reducing aerodynamic noise.

[0048] This silencer for the scroll compressor, through the cooperation of a first silencer space and a second silencer space, enables secondary noise reduction of the gas. The specially designed second silencer space effectively dissipates the gas's energy, thereby reducing aerodynamic noise. Using this silencer significantly reduces the aerodynamic noise of the scroll compressor, especially at high speeds, effectively addressing aerodynamic noise caused by gas pulsation. It is suitable for large-displacement scroll compressors. Since the silencer does not alter the original structure of the scroll compressor, it can substantially reduce noise without compromising energy efficiency, improving the compressor's sound quality and thus enhancing its product competitiveness.

[0049] In addition, such as Figure 8 As shown, according to a second aspect of the present invention, a scroll compressor is provided, the scroll compressor including the silencing device for a scroll compressor as described above. During operation, the scroll compressor can effectively reduce aerodynamic noise by using the silencing device.

[0050] Preferably, such as Figure 8 As shown, in this embodiment, the silencing device is disposed inside the scroll compressor. Specifically, the scroll compressor may include a housing 11 and a fixed plate 10. The silencing device may be disposed inside the housing 11 and installed on the top of the fixed plate 10.

[0051] This scroll compressor can significantly reduce aerodynamic noise by using a silencer, especially when the scroll compressor is running at high speed. It can solve the problem of aerodynamic noise caused by gas pulsation and is suitable for large displacement scroll compressors.
