Description

Technical Field

[0001] This application relates to the field of compressor noise reduction technology, and in particular to a flange structure, compressor and refrigeration equipment. Background Technology

[0002] Rotary compressors are widely used in refrigeration equipment due to their compact structure and stable operation, making them particularly suitable for household air conditioners, small commercial air conditioners, and some small refrigeration systems. They achieve gas intake, compression, and discharge through the rotation of two or more meshing rotors within a cylinder. This continuous motion of the compressor results in low vibration and high efficiency during operation, and its simple design leads to relatively low maintenance costs. Furthermore, rotary compressors maintain high energy efficiency over a wide operating range, making them highly favored in modern refrigeration equipment where energy conservation and environmental protection are paramount.

[0003] In traditional rotary compressors, the silencer and flange are separate structures. This structure increases flow resistance, reduces operating efficiency and increases energy consumption. When the airflow flows in multiple chambers, it is easy to generate turbulence, which generates noise and affects the user experience. Utility Model Content

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

[0024] To address the issues that existing separate silencer and flange structures increase flow resistance, reduce operating efficiency, and increase energy consumption, as well as the turbulence and noise generated when airflow flows through multiple chambers, thus affecting the user experience, this application provides a flange structure that integrates the compressor's silencer with the flange. Specifically, the silencer component 2 in this application is integrally formed with the flange body 1, and a silencer cavity 1b is enclosed within it. This allows the high-pressure gas generated by the compressor to be discharged through the silencer cavity 1b, thus avoiding the problem of turbulence and noise generated when airflow flows through multiple chambers.

[0025] Figures 1 to 7 A flange structure provided in this application embodiment is applied to a compressor. The flange structure includes a flange body 1, a silencer 2, and an exhaust valve 3. The flange body 1 has a connection hole 1a for connecting to a compression chamber 4a. The silencer 2 is integrally formed with the flange body 1, and the silencer 2 and the flange body 1 enclose a silencer chamber 1b. The silencer 2 has an exhaust hole 2a, and the silencer chamber 1b connects the connection hole 1a and the exhaust hole 2a. The exhaust valve 3 is connected to the silencer 2 and blocks the connection hole 1a. When the gas pressure in the compression chamber 4a increases, the exhaust valve 3 can open to allow high-pressure refrigerant to flow through the silencer chamber 1b and be discharged.

[0026] In this embodiment, the flange structure of this application achieves a tight integration of the flange body 1 and the silencer 2 through an integrated design, forming an integrated unit with a noise reduction function. Specifically, the flange body 1 is made of high-strength material to ensure that it can withstand various forces during the operation of the compressor. The connecting hole 1a is precisely machined on the flange body 1 and communicates with the compression chamber 4a, providing a channel for the high-pressure refrigerant. The silencer 2 and the flange body 1 are integrally formed through precision machining, enclosing a silencer chamber 1b. The chamber 1b is designed with multiple silencer chambers of different shapes and sizes, which are interconnected through specific channels to effectively reduce noise in different frequency bands.

[0027] It should be noted that combining the flange body 1 and the muffler 2 into a quasi-integrated structure achieves a high-strength connection, good sealing performance, and a gradual transition in mechanical properties, thereby improving the overall structural reliability and functionality. The flange body 1 and the muffler 2 can be joined using laser welding technology, which utilizes a high-energy-density laser beam to locally heat the materials, achieving a fusion connection between the two parts. This method offers high welding precision, a small heat-affected zone, reduces subsequent processing steps, and improves production efficiency. Alternatively, an embedded mounting groove design and a high-temperature expansion process can be employed. An embedded mounting groove is designed on the flange body 1 to accommodate the muffler 2. The muffler 2 is heated at a specific temperature, causing thermal expansion, and then placed into the mounting groove of the flange body 1. After cooling, due to material contraction, the muffler 2 and the flange body 1 form a tight fit, achieving a gapless connection, enhancing structural stability, improving sealing and vibration resistance, and avoiding the failure risks associated with traditional adhesive or screw connections. Alternatively, 3D printing (additive manufacturing) technology can be used to create a functionally graded material transition region between the flange body 1 and the muffler 2. The material composition gradually changes from the flange side to the two sides of the sound-absorbing component, achieving a gradual change in performance from rigid to flexible and from thermal conductivity to sound absorption.

[0028] Exhaust port 2a is located on the muffler 2 and connected to the muffler chamber 1b, ensuring that the refrigerant, after noise reduction treatment, can be discharged smoothly. Exhaust valve 3 is connected to the muffler 2 by means of threads or snaps, and blocks the connection port 1a during normal operation to prevent refrigerant leakage. When the gas pressure in the compression chamber 4a increases, exhaust valve 3 automatically opens, and high-pressure refrigerant enters the muffler chamber 1b through the connection port 1a. After undergoing noise reduction treatment in multiple chambers within the muffler chamber 1b, it is discharged through exhaust port 2a.

[0029] The integrated design of the flange body 1 and the silencer 2 reduces the number of parts and assembly time, lowering production costs while improving assembly accuracy and reliability. The silencer chamber 1b effectively reduces noise generated during high-pressure refrigerant discharge, enhancing the user experience and making the compressor quieter. The integrated structure enhances sealing performance, reduces leakage risk, and improves compressor reliability and lifespan. Optimized flow channel design reduces flow resistance, improving compressor operating efficiency and lowering energy consumption. This design allows for a more compact compressor design, saving space and making it particularly suitable for small refrigeration equipment such as residential and small commercial air conditioners. Overall, this application not only improves compressor performance but also addresses energy-saving and environmental requirements, demonstrating broad application prospects.

[0030] Please see Figures 1 to 3 In order to reduce the low-frequency noise generated by the refrigerant discharged from the compression chamber 4a into the silencing chamber 1b, the flange body 1 is provided with an expansion chamber 1c. The expansion chamber 1c is located at the end of the connection hole 1a near the silencing chamber 1b and is connected to the connection hole 1a.

[0031] In one embodiment, the shape of the expansion chamber 1c can be designed as an arc, cylinder, cuboid, or other suitable geometry to adapt to different compressor structures and noise reduction requirements. In the compressor of this application, the shape of the expansion chamber 1c is not overly limited, but in the axial direction of the connecting hole 1a, the cross-sectional area of ​​the expansion chamber is larger than that of the connecting hole 1a to better reduce low-frequency noise. The inner wall of the expansion chamber 1c can be smoothed to reduce airflow turbulence and further reduce noise. Appropriate transition areas can be provided at the inlet and outlet of the expansion chamber 1c to ensure smooth airflow into and out of the expansion chamber 1c. This design allows the high-pressure refrigerant to pass through the expansion chamber 1c before entering the silencing chamber 1b. Due to the larger volume of the expansion chamber 1c, the airflow velocity decreases due to the sudden expansion of the space, thereby effectively consuming low-frequency noise energy.

[0032] This flange structure with an expansion chamber 1c exhibits significant noise reduction, particularly in suppressing low-frequency noise. By placing the expansion chamber 1c at the end of the connection hole 1a near the silencing cavity 1b, the airflow velocity of the high-pressure refrigerant decreases due to the sudden expansion of the space before entering the silencing cavity 1b, thus dissipating some of the low-frequency noise energy and significantly reducing low-frequency noise. For example, in household air conditioner compressors, using this flange structure with an expansion chamber 1c can reduce low-frequency noise by approximately 5 to 10 decibels. Furthermore, the smooth inner wall of the expansion chamber 1c further reduces airflow turbulence, enhancing the noise reduction effect. This design not only improves the compressor's operating efficiency but also enhances the user experience, making the compressor operate more quietly. Simultaneously, due to the simple structure of the expansion chamber 1c, its processing cost is low, and it does not significantly increase the compressor's manufacturing cost. Overall, this flange structure with an expansion chamber 1c performs excellently in reducing low-frequency noise and has broad application prospects, particularly suitable for refrigeration equipment with high noise control requirements.

[0033] Please see Figure 3 and Figure 4 Since the high-pressure refrigerant gas flow rate in the compression chamber 4a is large, it is impossible for a single expansion chamber to completely receive the high-pressure refrigerant in a short time. Therefore, it is necessary to divert the high-pressure refrigerant. The expansion chamber 1c includes a first guide chamber 11a and a second guide chamber 11b. Both the first guide chamber 11a and the second guide chamber 11b are arranged along the circumference of the flange body 1 and in opposite directions.

[0034] In this embodiment, the first guide cavity 11a and the second guide cavity 11b can be designed as an arc or a fan shape to adapt to different compressor structures and noise reduction requirements. The arc shape of the first guide cavity 11a and the second guide cavity 11b allows the high-pressure refrigerant to be diverted into the two guide cavities before entering the silencer cavity 1b, effectively reducing the receiving pressure of the single expansion chamber 1c and ensuring smooth airflow into the silencer cavity 1b. Furthermore, the inner walls of the guide cavities can be smoothed to reduce airflow turbulence and further reduce noise. Appropriate transition areas can be provided at the inlet and outlet of the guide cavities to ensure smooth airflow into and out of the guide cavities.

[0035] This flange structure with two guide cavities significantly improves the diversion effect of high-pressure refrigerant, effectively reducing the receiving pressure of a single expansion chamber 1c. By diverting the high-pressure refrigerant into two guide cavities with opposite directions, the airflow velocity is reduced, and some low-frequency noise energy is consumed, thus significantly reducing low-frequency noise. The smooth inner wall of the guide cavities further reduces airflow turbulence, improving the noise reduction effect. This design not only improves the compressor's operating efficiency but also enhances the user experience, making the compressor operate more quietly. At the same time, due to the simple structure of the guide cavities and low processing costs, it does not significantly increase the manufacturing cost of the compressor. This flange structure with two guide cavities performs excellently in reducing low-frequency noise and has broad application prospects, especially suitable for refrigeration equipment with high noise control requirements.

[0036] Please see Figures 1 to 4 In order to reduce the high-frequency noise generated by the refrigerant discharged from the compression chamber 4a into the silencing chamber 1b, the silencing component 2 includes two high-frequency noise reduction chambers 2b. Both high-frequency noise reduction chambers 2b are arranged along the circumferential direction of the flange body 1. The first guide chamber 11a and the second guide chamber 11b are respectively connected to a high-frequency noise reduction chamber 2b.

[0037] In one embodiment of this application, the high-frequency noise reduction chamber 2b can be designed as a wave-shaped channel with continuously changing volume to increase airflow resistance and dissipate high-frequency noise energy. This design allows the high-pressure refrigerant to further enter the high-frequency noise reduction chamber 2b after passing through the first guide chamber 11a and the second guide chamber 11b. The resistance of the wave-shaped channel effectively dissipates high-frequency noise energy. This flange structure with two high-frequency noise reduction chambers 2b significantly improves the noise reduction effect on high-frequency noise. By designing the high-frequency noise reduction chamber 2b as a wave-shaped channel structure with continuously changing volume, airflow resistance is increased, effectively dissipating high-frequency noise energy. This design not only improves the compressor's operating efficiency but also enhances the user experience, making the compressor operate more quietly. Because the high-frequency noise reduction chamber 2b has a simple structure and low processing cost, it does not significantly increase the manufacturing cost of the compressor.

[0038] Please see Figures 1 to 4 In order to further improve the high-frequency noise reduction effect of the high-frequency noise reduction chamber 2b, each of the two high-frequency noise reduction chambers 2b is provided with at least one buffer cavity 2c, and the cross-sectional area of ​​the buffer cavity 2c is larger than the cross-sectional area of ​​the high-frequency noise reduction chamber 2b.

[0039] In this embodiment, to further enhance the noise reduction effect of the high-frequency noise reduction chamber 2b, at least one buffer cavity 2c is designed in each of the two high-frequency noise reduction chambers 2b. The cross-sectional area of ​​these buffer cavities 2c is larger than that of the high-frequency noise reduction chamber 2b to provide more space for buffering and dispersing airflow, thereby more effectively reducing high-frequency noise. The buffer cavity 2c can be designed as circular, fan-shaped, or other suitable shapes, as long as the cross-sectional area of ​​the buffer cavity 2c is larger than the cross-sectional area of ​​other locations in the high-frequency noise reduction chamber 2b. The buffer cavities 2c are connected to the high-frequency noise reduction chamber 2b through airflow channels, which ensure that airflow can smoothly enter the buffer cavity 2c.

[0040] This high-frequency noise reduction chamber 2b design with a buffer cavity 2c significantly enhances the noise reduction effect on high-frequency noise. By incorporating a buffer cavity 2c with a larger cross-sectional area within the high-frequency noise reduction chamber 2b, the airflow velocity decreases upon entering the buffer cavity 2c, dissipating some of the high-frequency noise energy and further reducing high-frequency noise. This design not only improves the compressor's operating efficiency but also enhances the user experience, making the compressor operate more quietly. Due to the simple structure and low processing cost of the buffer cavity 2c, it does not significantly increase the compressor's manufacturing cost. This high-frequency noise reduction chamber 2b with a buffer cavity 2c performs excellently in reducing high-frequency noise and has broad application prospects, particularly suitable for refrigeration equipment with high noise control requirements.

[0041] Please see Figure 1 In order to slow down the speed at which the high-pressure and high-speed refrigerant flows out of the silencer chamber 1b, this application has made a specific setting on the extension direction of the two high-frequency noise reduction chambers 2b. Specifically, the two high-frequency noise reduction chambers 2b extend in opposite directions, and both high-frequency noise reduction chambers 2b are connected to the exhaust port 2a.

[0042] In one embodiment of this application, the two high-frequency noise-canceling chambers 2b extend in opposite directions and are both connected to the exhaust port 2a. The high-frequency noise-canceling chambers 2b can be designed to extend along the circumference of the flange body 1 in opposite directions. In a household air conditioner compressor, the first high-frequency noise-canceling chamber 2b can extend clockwise, while the second high-frequency noise-canceling chamber 2b extends counterclockwise. Each high-frequency noise-canceling chamber 2b has the same length and width. After the high-pressure refrigerant flows out of the compression chamber 4a, it directly enters the first guide chamber 11a and the second guide chamber 11b through the connecting hole 1a to attenuate low-frequency noise. The refrigerant, after noise reduction, is guided by the first guide chamber 11a and the second guide chamber 11b to enter a high-frequency noise-canceling chamber 2b to reduce high-frequency noise. During this process, the refrigerant is buffered by the buffer chamber 2c, and then further decelerates after partially offsetting its kinetic energy at the connection point between the two high-frequency noise-canceling chambers 2b near the exhaust port, finally exiting the exhaust port. This opposing extension direction causes the refrigerant airflow directions to partially cancel each other out as it passes through the two high-frequency noise-canceling chambers 2b, thus slowing down the airflow speed. After being connected, the two high-frequency noise-canceling chambers 2b are directly connected to the exhaust port 2a to further control the airflow speed. This design not only slows down the refrigerant's outflow speed but also increases the noise reduction effect by extending the airflow path.

[0043] This specifically designed high-frequency noise-canceling chamber 2b significantly slows down the velocity of the high-pressure, high-speed refrigerant flowing out of the noise-canceling chamber 1b, thereby further reducing noise. By aligning the two high-frequency noise-canceling chambers 2b in opposite directions, the kinetic energy of the airflow partially cancels each other out as it passes through these chambers, effectively slowing down the airflow velocity. For example, in a household air conditioner compressor, using this design can reduce the refrigerant outflow velocity by approximately 30% and the noise level by approximately 10 decibels. This design not only improves the compressor's operating efficiency but also enhances the user experience, making the compressor run more quietly. This structure is simple, has low processing costs, and does not significantly increase the compressor's manufacturing cost.

[0044] Please see Figures 1 to 2 Since the noise reduction capability generated by the structural improvement of the silencing cavity 1b itself is limited, in order to further increase the noise reduction capability of the silencing cavity 1b, a noise-absorbing layer is provided on the inner wall of the silencing cavity 1b.

[0045] In this embodiment, the noise-absorbing layer is made of a material with high sound absorption performance, such as porous metal, foam plastic, glass fiber, or sound-absorbing sponge. The noise-absorbing layer can be fixed to the inner wall of the anechoic chamber 1b by means of bonding, spraying, or embedding. The surface of the noise-absorbing layer can be designed with an uneven structure to increase the contact area of ​​the airflow and further improve the sound absorption effect. Furthermore, the material of the noise-absorbing layer can be selected and adjusted according to different compressor models and noise reduction requirements to achieve the best noise reduction effect. This design of setting a noise-absorbing layer on the inner wall of the anechoic chamber 1b significantly enhances the noise reduction capability of the anechoic chamber 1b. By using materials with high sound absorption performance, such as sound-absorbing sponge or glass fiber, the noise-absorbing layer can effectively absorb and dissipate noise energy in the airflow, further reducing the noise level. The uneven surface of the noise-absorbing layer increases the contact area of ​​the airflow, further improving the sound absorption effect.

[0046] This design not only improves compressor operating efficiency but also enhances the user experience, making the compressor run quieter. The material of the noise-absorbing layer can be selected and adjusted according to different compressor models and noise reduction requirements, offering high flexibility and adaptability. Overall, this design performs excellently in noise reduction and has broad application prospects, particularly suitable for refrigeration equipment with high noise control requirements.

[0047] Please see Figure 1 and Figure 7 To facilitate the installation of the flange structure into the compressor, mounting holes 1d are provided on the outer periphery of the flange body 1, and the mounting holes 1d penetrate the opposite side walls of the flange body 1.

[0048] In one embodiment, these mounting holes 1d penetrate the opposite side walls of the flange body 1, allowing the flange to be fixed to the corresponding position on the compressor by bolts, screws, or other fasteners. The number and position of the mounting holes 1d can be adjusted according to the specific design of the compressor. The shape of the mounting holes 1d is generally circular, and the edges of the mounting holes 1d can be chamfered or rounded to reduce stress concentration and improve the mechanical strength and service life of the flange. Because the flange body 1 is structurally integrated with the silencer 2, the mounting holes 1d are optimized to address the design limitations of the mounting holes 1d and the size and shape of the silencer cavity 1b, such as... Figure 7As shown, for the flange structure, the silencer 2 is directly enlarged and integrated with the flange as a whole. This design not only simplifies the installation process of the flange structure but also ensures the stability and reliability of the flange within the compressor. The design of opening mounting holes 1d on the outer periphery of the flange body 1 significantly improves the ease of installation and stability of the flange structure. By evenly distributing the mounting holes 1d on the outer periphery of the flange body 1, the flange can be firmly fixed inside the compressor using standard bolts or screws, ensuring its stability during operation. The edges of the mounting holes 1d are chamfered or rounded, reducing stress concentration and improving the mechanical strength and service life of the flange. This design not only simplifies the installation process but also reduces installation costs and improves production efficiency.

[0049] Secondly, please refer to Figure 5 and Figure 6 This application provides a compressor, including a compression chamber 4a and a flange structure proposed in the first aspect of this application, with a connection hole 1a connecting the compression chamber 4a and the silencer chamber 1b.

[0050] This application provides a compressor comprising a compression chamber 4a and a flange structure as described in the first aspect of this application. This flange structure communicates with the compression chamber 4a via a connection hole 1a, allowing the high-pressure refrigerant in the compression chamber 4a to smoothly enter the silencer chamber 1b. Specifically, the compression chamber 4a and the flange structure are precision-machined to ensure accurate alignment between the connection hole 1a and the compression chamber 4a. The inner wall of the connection hole 1a can be smoothed to reduce airflow turbulence and resistance. The mounting hole 1d of the flange structure is used to securely fix the flange inside the compressor, ensuring the stability of the flange structure during operation. This design not only ensures the smooth entry of high-pressure refrigerant into the silencer chamber 1b but also effectively reduces the operating noise of the compressor through the silencing function of the flange structure.

[0051] This compressor design, through the integration of the flange structure proposed in this application, significantly improves the compressor's noise reduction performance and operational stability, as detailed in the table below. The compression chamber 4a is connected to the silencing chamber 1b via connection hole 1a. The high-pressure refrigerant undergoes silencing treatment by the flange structure before entering the silencing chamber 1b, effectively reducing noise levels. The mounting hole 1d of the flange structure ensures a secure installation of the flange within the compressor, enhancing operational stability.

[0052] Thirdly, this application provides a refrigeration device, including the compressor proposed in the second aspect of this application.

[0053] In this application, the refrigeration equipment can be a household air conditioner, a small commercial air conditioner, or a refrigerator, etc. The compressor's flange structure is connected to the compression chamber 4a through the connection hole 1a, ensuring that the high-pressure refrigerant smoothly enters the silencing chamber 1b for noise reduction. This design of the refrigeration equipment, through the integrated and optimized compressor, significantly improves the overall operating efficiency and noise reduction performance. By using the compressor proposed in this application, the refrigeration equipment operates more quietly, with the noise level reduced by approximately 6 decibels, significantly improving the user experience. For example, in a household air conditioner, with this design, users can hardly hear the compressor running indoors, thus enjoying a more comfortable environment.
