[0031] In order to more clearly understand the above-mentioned purposes, features and advantages of the embodiments of the present application, the embodiments of the present application are further described in detail below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that the embodiments of the present application and the features therein can be combined with each other in the absence of conflict.

[0032] In the following description, many specific details are set forth to facilitate a full understanding of the present application. However, the embodiments of the present application may also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present application is not limited to the specific embodiments disclosed below.

[0033] Some embodiments according to the present application are described below with reference to FIG. 1 to FIG. 7 .

[0034] As shown in FIG1 , an exhaust assembly 100 proposed in this embodiment mainly includes a crankcase 102, an exhaust cylinder head 104, and an exhaust pipe 106. Multiple exhaust cylinders 1022 are provided in the crankcase 102 to achieve parallel exhaust, effectively reducing exhaust pressure by diverting the exhaust gas. In some embodiments, the crankcase 102 is the foundation of the exhaust assembly 100, and its main function is to provide support and accommodate multiple exhaust cylinders 1022. The exhaust cylinders 1022 are the main locations for gas compression and discharge, which can affect the efficiency of gas flow and the reduction of exhaust noise. The exhaust cylinder head 104 closes the top of the exhaust cylinder 1022, ensuring that the gas remains in the appropriate channel during the compression and discharge process. The multiple exhaust cylinder bodies 1022 can be connected through the exhaust pipe 106 via the exhaust cylinder head 104. The specific connection relationship is that the gas in two exhaust cylinders will move and eventually flow out through the exhaust cylinder head 104 of one exhaust cylinder body 1022. Since the multiple exhaust cylinder bodies 1022 are connected in parallel, a part of the gas in the exhaust cylinder body 1022 will flow into the other exhaust cylinder body 1022 through the exhaust pipe 106 on the exhaust cylinder head 104, so that the airflow can be mixed, and the gas between the two exhaust cylinder bodies 1022 will collide, thereby alleviating exhaust pulsation and reducing exhaust noise.

[0035] Among them, the exhaust pipe 106 mainly includes two pipe sections, specifically an inner pipe section 1062 and an outer pipe section 1064. Among them, the inner pipe section 1062 is connected to the two exhaust cylinder blocks 1022, and the specific connection position is set on the exhaust cylinder head 104. The inner pipe section 1062 is connected to the two exhaust cylinder heads 104 to connect the two exhaust cylinder blocks 1022, thereby guiding the gas to flow between the two exhaust cylinder blocks 1022. The outer pipe section 1064 is used to discharge the gas in multiple exhaust cylinder blocks 1022 together. This solution optimizes the flow of gas and reduces exhaust pulsation and noise. The combination of the inner pipe section 1062 and the outer pipe section 1064 makes the exhaust process smoother and reduces noise generation by reasonably guiding the gas flow, thereby improving the performance of the entire exhaust system.

[0036] It should be noted that the inner pipe section 1062 connects the two exhaust cylinders 1022, allowing gas to flow from one exhaust cylinder 1022 to the other during the exhaust process. This helps to smoothly divert the gas, reduce exhaust pulsation, and thus reduce noise levels.

[0037] It should be emphasized that since the length of the inner tube section in the present application is shorter than that in the prior art, there is almost no need to reshape the inner tube, which is conducive to ensuring the consistency of the inner tube and improving manufacturability.

[0038] The outer pipe section 1064 isolates the exhaust cylinder head 104 from the external environment, preventing the exhaust gas from interfering with the external environment and helping to reduce the spread of noise. At the same time, this outer pipe section 1064 is also used to guide the exhaust gas out of the equipment.

[0039] In one specific embodiment, as shown in FIG3 , a slotted structure 1066 is provided on the outer pipe section 1064. This, on the one hand, can guide the gas through the exhaust pipe 106 more smoothly during the exhaust process. This prevents the gas from experiencing sudden obstructions during flow, reducing turbulence and instability in the gas flow, thereby reducing noise. On the other hand, during the exhaust process, the gas may experience reverse flow, meaning that the gas flows back into the exhaust pipe 106 after being discharged. The presence of the slotted structure 1066 can effectively reduce backflow, thereby preventing the gas from repeatedly entering the exhaust system and reducing the possibility of noise and vibration.

[0040] At the same time, the provision of the slotted structure 1066 helps disperse the pressure pulsations generated by the gas flow, thereby reducing the noise of the gas flow. The slots can reduce the friction and impact between the gas and the pipe wall during the gas flow, thereby reducing the noise level.

[0041] Based on some embodiments, for example, one end of the inner pipe section 1062 is positioned toward the flow hole 1068 in the exhaust cylinder 1022, thereby directing the gas during the exhaust process into the exhaust cylinder 1022. This diversion helps optimize the gas flow path, reduces gas backflow and turbulence, and further helps smooth the gas flow, reducing gas pulsation in the exhaust pipe 106. Pulsating airflow can easily cause noise. By directing the gas into the exhaust cylinder 1022, the instability of the airflow can be reduced, thereby lowering the noise level.

[0042] In some embodiments, for example, elastic members 1070 are provided. These members can absorb some of the vibration and impact during the exhaust process, thereby reducing the transmission of vibration and shock to the exhaust system and the entire refrigeration equipment 300. This helps reduce noise levels and extend the life of the equipment. Of course, elastic members 1070 can also provide a certain damping effect, reducing impact and vibration during gas flow, thereby reducing noise generation. They can act as a buffer in gas flow, ensuring smoother airflow.

[0043] Furthermore, during operation of refrigeration equipment 300, temperature fluctuations can cause thermal expansion of components, potentially affecting the tightness of the exhaust system connection. By installing elastic members 1070 around the outer sides of inner pipe sections 1062, these thermal expansion-related connection issues can be mitigated to a certain extent, maintaining normal system operation.

[0044] In some embodiments, as shown in FIG2 , each exhaust cylinder 1022 is connected to the cylinder surface of the crankcase 102 via a flow hole 1068. This arrangement can divert the gas within the exhaust cylinder 1022 into the crankcase 102. This diversion allows the gas to flow more evenly into the crankcase 102, thereby reducing pressure differences within the exhaust cylinder 1022 and facilitating reduced exhaust pulsation and noise.

[0045] When the gas is diverted to the crankcase 102, part of the exhaust pressure is dispersed into the crankcase 102, thereby reducing the gas pressure in the exhaust cylinder 1022. This helps to reduce the internal pressure difference of the exhaust system, alleviates the impact and vibration of the gas when it flows in the exhaust pipe 106, and thus reduces the noise level.

[0046] The provision of multiple flow holes 1068 allows gas to flow more smoothly into the crankcase 102. This helps reduce turbulence and eddies in the gas flow, thereby reducing noise generation. Smooth airflow also helps improve the efficiency of the exhaust system.

[0047] To summarize, as shown in FIG5 , the exhaust cylinder 1022 is connected to the cylinder surface of the crankcase 102 through a plurality of flow holes 1068 , which can effectively divert gas, reduce exhaust pressure, stabilize airflow, and optimize gas circulation, thereby reducing exhaust pulsation and noise, and improving the performance and reliability of the refrigeration equipment 300 .

[0048] In one specific embodiment, there are two exhaust cylinders 1022, which are located on opposite sides of the crankcase 102. Placing the two exhaust cylinders 1022 on opposite sides of the crankcase 102 achieves better balance. As will be appreciated, balance is crucial for the stable operation of mechanical equipment, particularly during high-speed operation, where it reduces vibration and shock, thereby reducing noise and losses. Furthermore, exhaust pulsation is more evenly distributed between the two exhaust cylinders 1022, which helps reduce the exhaust pulsation amplitude within a single exhaust cylinder 1022, thereby reducing the noise level of the entire exhaust system.

[0049] Of course, providing two exhaust cylinders 1022 can achieve a symmetrical layout, thereby generating a more uniform gas flow during the exhaust process, which helps to optimize gas circulation and distribution, reduce unstable gas flow, and reduce exhaust pulsation and noise.

[0050] In one embodiment, as shown in FIG4 , a first connection hole 1102 on the exhaust cylinder block 1022, a second connection hole 1104 on the exhaust cylinder head 104, and a fastening member 1106 are provided to ensure a secure connection between the exhaust cylinder head 104 and the exhaust cylinder block 1022. This helps prevent the exhaust system from loosening or leaking during operation, thereby improving system reliability.

[0051] The connector 1106 is used to connect the exhaust cylinder head 104 and the exhaust cylinder block 1022 , making the assembly and disassembly process more convenient.

[0052] The secure connection of connector 1106 ensures airtightness between exhaust cylinder body 1022 and exhaust cylinder head 104, preventing gas leakage and energy loss. Furthermore, this reduces gas leakage in the exhaust system, thereby reducing noise during the exhaust process. This helps improve the operating efficiency and user comfort of refrigeration equipment 300.

[0053] On this basis, a seal 112 is provided, which can effectively fill the gap between the exhaust cylinder cover 104 and the exhaust cylinder body 1022, ensuring the airtightness of the connection part. This will help prevent gas leakage and ensure the normal operation of the refrigeration system.

[0054] As can be appreciated, seal 112 can reduce the possibility of gas leakage in the exhaust system, thereby improving the efficiency and performance of the refrigeration system. It can also reduce the noise caused by gas leakage during the exhaust process, thereby improving the operating environment of the system. Of course, seal 112 can also prevent dust, impurities, and other foreign matter from entering the exhaust system, preventing these substances from affecting the normal operation of the system.

[0055] As shown in FIG6 , another embodiment of the present application proposes a compressor 200 , which includes the exhaust assembly 100 of the above-mentioned first embodiment. Therefore, the compressor 200 provided in the present application has all the beneficial effects of any of the above-mentioned exhaust assemblies 100 .

[0056] As shown in Figure 7, another embodiment of the present application proposes a refrigeration device 300, which includes a box body 302 and a refrigeration cabinet and a compressor 200 arranged in the box body 302. The compressor 200 can cool the refrigeration cabinet, and the refrigeration cabinet mainly plays a role in heat preservation. Since the compressor 200 is arranged in the box body 302, it has the beneficial effects of the above-mentioned compressor 200 or any exhaust component 100, which will not be repeated here.

[0057] According to the exhaust assembly, compressor and refrigeration equipment provided in the present application, by setting up multiple exhaust cylinders and arranging exhaust pipes, the airflow can be mixed, and the gas between the two exhaust cylinders will collide, thereby alleviating exhaust pulsation and reducing exhaust noise.
