Description

Technical Field

[0001] This utility model relates to the field of centrifuge compressor technology, and in particular to a cooler for centrifuge compressors. Background Technology

[0002] A centrifugal compressor is a mechanical device that uses the principle of centrifugal force to compress gas. It belongs to the category of turbine compressors in fluid machinery. It mainly consists of a rotating impeller and fixed diffuser, volute and other components. The high-speed rotation of the impeller enables the gas to gain kinetic energy and pressure energy. Then, in the diffuser and volute, some of the kinetic energy is converted into pressure energy, thereby realizing the compression and transportation of the gas.

[0003] In some existing centrifuge compressor applications, the compressor temperature rises during operation due to the heat generated by the high-speed rotating mechanical parts and gas compression. Excessive temperature reduces compressor efficiency and may even damage mechanical parts, shortening the equipment's lifespan.

[0004] Therefore, this utility model provides a cooler for a centrifuge compressor. Utility Model Content

[0005] The purpose of this invention is to address the shortcomings of existing technologies and provide a cooler for centrifuge compressors.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a cooler for a centrifuge compressor, comprising a housing;

[0007] A drive rotation assembly; the drive rotation assembly includes an internal rotating shaft rotatably connected inside the housing, both ends of the internal rotating shaft penetrating the interior of the housing and extending outwards;

[0008] Heat dissipation assembly; the heat dissipation assembly includes a heat dissipation fan fixedly connected to an internal rotating shaft, a plurality of heat dissipation fins fixedly connected to one end of the housing near the heat dissipation fan, a guide groove is provided on one side of the heat dissipation fins near the housing, and a through groove is provided inside the housing near the guide groove.

[0009] In a preferred embodiment, a drive gear is rotatably connected to the outer side of the housing away from the cooling fan, and a driven gear is rotatably connected to the outer side of the housing near the drive gear.

[0010] In a preferred embodiment, a centrifugal rotating shaft is fixedly connected to the outer side of the internal rotating shaft, and the outer sides of the two centrifugal rotating shafts are meshed.

[0011] In a preferred embodiment, air inlets and outlets are fixedly connected to both ends of the outer side of the housing, and an extension port is fixedly connected to the top of the housing.

[0012] In a preferred embodiment, the driving gear and the driven gear are meshed.

[0013] In a preferred embodiment, the outer side of the cooling fan is mounted on the outer side of the housing, and one side of the cooling fan is fixedly connected to the outer side of the heat sink.

[0014] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0015] This invention uses a power source to drive a driving gear to rotate. The driving gear meshes with a driven gear, which in turn drives an internal rotating shaft to rotate, thereby driving a centrifugal rotating shaft and an impeller to rotate at high speed, compressing gas and pushing it towards the outlet. Simultaneously, a cooling fan fixedly connected to the internal rotating shaft rotates, generating airflow that is guided through guide channels and slots, flowing evenly over heat sinks. The heat sinks conduct heat to their surfaces and dissipates it rapidly into the surrounding environment through the airflow. The advantage of this design is that it effectively reduces the operating temperature of the cooler and centrifugal compressor, preventing excessively high temperatures from affecting equipment efficiency and lifespan. It effectively avoids problems such as reduced compressor efficiency and damage to mechanical components due to excessive temperature, thus extending the equipment's lifespan and improving its operational stability.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] like Figure 1 - Figure 2 As shown, this embodiment provides a technical solution: a cooler for a centrifuge compressor, including a housing 1, with inlet and outlet ports 4 fixedly connected to both ends of the outer side of the housing 1, and an extension port 5 fixedly connected to the top of the housing 1;

[0027] The housing 1 serves as the main outer shell of the cooler, providing a closed space for the internal cooling components and the gas being cooled, thus playing a protective and support role. It also helps maintain the stability and safety of the cooling process. The inlet and outlet ports 4 are located at both ends of the outer side of the housing 1. They are used to introduce high-temperature compressed gas and discharge cooled gas, respectively. The inlet port introduces the high-temperature gas discharged from the centrifuge compressor into the cooler, while the outlet port sends the cooled gas back to the centrifuge compressor or other related equipment. The extension port 5 provides an interface for the cooler to connect with external systems, facilitating the introduction and discharge of the cooling medium, or for installing monitoring devices such as pressure gauges and thermometers.

[0028] like Figure 1 - Figure 3 As shown, the drive rotation assembly 2 includes an internal rotating shaft 23 rotatably connected inside the housing 1. Both ends of the internal rotating shaft 23 penetrate the interior of the housing 1 and extend outward. A drive gear 21 is rotatably connected to the outer end of the housing 1 away from the cooling fan 34, and a driven gear 22 is rotatably connected to the outer end of the housing 1 near the drive gear 21. The drive gear 21 and the driven gear 22 are meshed. A centrifugal rotating shaft 24 is fixedly connected to the outer side of the internal rotating shaft 23, and the outer sides of the two centrifugal rotating shafts 24 are meshed.

[0029] The housing 1 serves as the mounting base and protective shell for the drive rotating assembly 2, providing support and protection for the internal transmission components and preventing external impurities from entering and affecting the normal operation of the transmission system. The internal rotating shaft 23 is one of the core components of the drive rotating assembly 2. It is rotatably connected inside the housing 1 and is used to transmit power. Both ends of the internal rotating shaft 23 penetrate the housing 1. One end is connected to the drive gear 21, and the other end is connected to the centrifugal rotating shaft 24, thereby transmitting power from the drive gear 21 to the centrifugal rotating shaft 24. The drive gear 21 and the driven gear 22 are meshed together to form a gear transmission system. The drive gear 21 is usually connected to the power source, receiving power and transmitting it to the driven gear 22, thereby driving the internal rotating shaft 23 to rotate. The centrifugal rotating shaft 24 is fixedly connected to the outside of the internal rotating shaft 23. The two centrifugal rotating shafts 24 are meshed together. The main function of the centrifugal rotating shaft 24 is to further transmit the power transmitted from the internal rotating shaft 23 to the impeller and other rotating components of the centrifugal compressor, so that it generates centrifugal force, thereby achieving gas compression.

[0030] like Figure 2 - Figure 4 As shown, the heat dissipation assembly 3 includes a heat dissipation fan 34 fixedly connected to the internal rotating shaft 23. A plurality of heat dissipation fins 31 are fixedly connected to one end of the housing 1 near the heat dissipation fan 34. A guide groove 32 is provided on one side of the heat dissipation fins 31 near the housing 1. A through groove 33 is provided inside the housing 1 near the guide groove 32. The outer side of the heat dissipation fan 34 is installed on the outer side of the housing 1. One side of the heat dissipation fan 34 is fixedly connected to the outer side of the heat dissipation fins 31.

[0031] The heat sink 31 is fixedly connected to the end of the housing 1 near the cooling fan 34. Its main function is to increase the heat dissipation area and improve the heat dissipation efficiency. The airflow guide groove 32 is opened on the side of the heat sink 31 near the housing 1. Its main function is to guide the airflow direction so that the air can flow more evenly over the surface of the heat sink 31 and improve the heat dissipation effect. The through groove 33 is opened inside the housing 1 near the end of the airflow guide groove 32. Its main function is to promote the exchange of air between the inside and outside of the housing 1 and enhance the heat dissipation effect. The cooling fan 34 is fixedly connected to the outside of the heat sink 31 and installed on the outside of the housing 1. The main function of the cooling fan 34 is to generate airflow by rotating to carry away the heat dissipated by the heat sink 31.

[0032] Working principle:

[0033] like Figure 1 - Figure 4 As shown:

[0034] In operation: During the operation of the centrifuge compressor cooler, the power source first drives the drive gear 21 to rotate. The drive gear 21 meshes with the driven gear 22, thereby driving the driven gear 22 to rotate synchronously. The driven gear 22 is installed at one end of the internal rotating shaft 23, and its rotation in turn drives the internal rotating shaft 23 to rotate. The other end of the internal rotating shaft 23 is fixedly connected to the centrifugal rotating shaft 24. Therefore, the rotation of the internal rotating shaft 23 will inevitably drive the centrifugal rotating shaft 24 to rotate together. The rotation of the centrifugal rotating shaft 24 directly drives the impeller of the centrifuge compressor to rotate at high speed. The gas is compressed and pushed to the outlet under the action of centrifugal force, realizing the gas compression process. At the same time, the cooling fan 34 fixedly connected to the internal rotating shaft 23 also rotates. The rotation of the cooling fan 34 generates airflow outside the housing 1. This airflow is guided by the guide groove 32 and the through groove 33 and flows evenly over the heat sink 31. The heat sink 31 conducts the heat inside the housing 1 to its surface. With the help of the flowing airflow, the heat is quickly dissipated to the surrounding environment, thereby effectively reducing the working temperature of the cooler and ensuring the efficient and stable operation of the cooler and centrifugal compressor.

[0035] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the form of the present utility model. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in their field. 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.
