Description

Technical Field

[0001] The utility model relates to the technical field of air compressors, in particular to a screw air compressor with a high-efficiency heat dissipation structure. Background Art

[0002] In automotive production workshops, numerous pneumatic tools are used to assemble auto parts, such as pneumatic wrenches for tightening screws and paint spray guns. Rotary screw air compressors provide a stable source of compressed air for these tools. Due to the dense equipment and high workload in automotive manufacturing workshops, prolonged operation of air compressors generates significant heat. Rotary screw air compressors with efficient heat dissipation structures effectively dissipate heat, ensuring stable operation in high-temperature environments. This prevents efficiency loss or malfunctions due to overheating, thereby ensuring continuous automotive production.

[0003] Some existing air compressors typically use flange connections. Flanges are installed on the compressor outlet and pipe, each with evenly spaced bolt holes. When docking, the two flanges are aligned, with a gasket placed between them. Bolts are then inserted through the bolt holes and tightened with nuts to secure the flanges.

[0004] However, the inability to directly connect to pipes during use means that additional adapters or pipe fittings are required during installation, which increases the complexity and difficulty of installation. Compared to air compressors that can directly connect to pipes, the additional adapters or pipe fittings also increase installation costs. If these components are of poor quality or improperly installed, they can also cause leakage and other problems, affecting the normal operation of the air compressor. Therefore, to address the above issues, a screw air compressor with a high-efficiency heat dissipation structure is proposed. Utility Model Content

[0005] In order to make up for the above deficiencies, the present invention provides a screw air compressor with a high-efficiency heat dissipation structure, aiming to improve the problems of some devices in the prior art.

[0023] The utility model has the following beneficial effects:

[0024] 1. In this utility model, the docking ring is connected to the docking pipe, ensuring that compressed air can be smoothly delivered to the external system. When no external pipe is connected, the spring of the elastic assembly is in a natural state. When the rotating plate is subjected to external force during the connection or removal process, the spring will compress or stretch accordingly, storing or releasing elastic potential energy, thereby assisting in connection, resetting, and maintaining the stability of the connection. Good pipe docking reduces the chance of external impurities and moisture entering the compressed air system, helping to maintain the cleanliness and dryness of the compressed air, thereby improving the quality of the compressed air.

[0025] 2. In the present invention, the condenser is a core component that uses its good thermal conductivity to quickly transfer heat. A protective cover is installed at the bottom of the condenser, and multiple fan blades are installed inside. The fan blades generate airflow through rotation to promote heat dissipation. During the operation of the screw air compressor, the compressed air will increase the internal temperature of the machine. If the heat cannot be effectively dissipated, the excessively high temperature will cause the gas density to decrease, affecting the exhaust volume and exhaust pressure of the air compressor. By dissipating heat from the main body, the internal temperature of the machine is kept within a reasonable range, ensuring that the air compressor can stably output sufficient compressed air to meet the needs of gas-using equipment.

Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figures 1 to 3 A screw air compressor with a highly efficient heat dissipation structure includes an installation box 1, which serves as the external protection and support structure for the entire screw air compressor. It is typically constructed of a durable and stable metal material, such as carbon steel or stainless steel. The carbon steel installation box offers high strength and toughness, capable of withstanding the weight of the equipment as well as the vibration and impact generated during operation. Multiple bases 2 are fixedly connected to the interior of the installation box 1. These bases 2 serve as the foundation for supporting the compressor body 4 and are typically constructed of a metal, such as cast iron or alloy steel, offering high strength and rigidity. The cast iron base 2 has good shock absorption performance and stability, which can effectively reduce the vibration generated by the air compressor body 4 during operation and transmit it to the installation box 1 and the ground, protecting the equipment and the surrounding environment; the top of the base 2 is fixedly connected to a support frame 3, which is usually L-shaped or U-shaped. Its size is determined according to the external dimensions and installation requirements of the air compressor body 4, and its thickness is determined according to the force and strength requirements. The top of the support frame 3 is fixedly connected to the air compressor body 4. The air compressor body 4 is the core component for generating compressed air, and its interior contains key components such as the screw rotor, motor, and oil-gas separation system. The screw rotor is made of high-quality alloy steel material and has a high-precision processing technology to ensure the matching accuracy and sealing between the rotors, thereby improving compression efficiency and air quality;

[0035] The outside of the air compressor body 4 is fixedly connected with a docking mechanism, and the inside of the installation box 1 is fixedly connected with an oil-gas separator 15. The oil-gas separator 15 is a key device for separating oil droplets and moisture in the compressed air in the air compressor system, and its material is generally selected from stainless steel or carbon steel. The stainless steel oil-gas separator has good corrosion resistance and strength, can adapt to various complex working environments, and the internal structure is not easy to rust or corrode, ensuring the long-term stability of the separation effect; the top of the installation box 1 is rotatably connected with a heat dissipation mechanism, which can effectively reduce the heat generated by the air compressor during operation and ensure the normal operating temperature of the equipment. The heat dissipation mechanism includes a rotating plate 2 16. The rotating plate 2 16 serves as a component that supports the fixed rod 17 and drives the entire heat dissipation mechanism to rotate. Its material is generally metal, such as stainless steel or alloy steel, and has high strength and rigidity. The outside of the rotating plate 2 16 is fixedly connected with a fixed rod 17. The fixed rod 17 serves as a component that supports the card plate 18 and the condenser 19. Its material is generally metal, such as stainless steel or alloy steel, and has high strength and rigidity.

[0036] Fixed rod 17 is cylindrical in shape, with its diameter determined by the aperture of clips 18 and the required support strength. Multiple clips 18 are fixedly attached to the exterior of fixed rod 17. Clips 18, which serve as the components that secure condenser 19, are typically made of sheet metal, such as steel or aluminum, offering a certain level of strength and rigidity. Condenser 19 is also fixedly attached to the exterior of clips 18. As a core component of the heat dissipation mechanism, condenser 19 is typically made of a metal material with good thermal conductivity, such as copper or aluminum. Copper condensers 19 have high thermal conductivity and can quickly transfer heat, but they are relatively expensive. Aluminum condensers 19 offer advantages in cost and weight, and their thermal conductivity also meets general heat dissipation requirements, making them more suitable for applications with high cost and weight requirements. A protective cover 20 is fixedly attached to the bottom of condenser 19. Shield 20 protects fan blades 21 and guides airflow, and is typically made of sheet metal, such as steel or aluminum, offering a certain level of strength and rigidity. The protective cover 20 is internally rotatably connected to a plurality of fan blades 21. These blades, which generate airflow and promote heat dissipation, are typically made of plastic or metal. Plastic fan blades offer advantages such as low cost, light weight, and excellent insulation. They can be injection molded into various shapes and angles to meet varying airflow requirements. The external portion of the rotating plate 2 16 is rotatably connected to the exterior of the mounting box 1.

[0037] The docking mechanism includes a connecting block 5, which serves as a transition component connecting the air compressor body 4 and the docking ring 6. The connecting block 5 is generally made of metal, such as stainless steel or aluminum alloy, and has a certain strength and rigidity. The stainless steel connecting block has good corrosion resistance and strength, can work stably for a long time in the air compressor operating environment, and is not easily deformed or damaged; the top of the connecting block 5 is fixedly connected to the docking ring 6. The docking ring 6 is a component that directly docks with external pipes or equipment. The material of the metal is generally metal, such as carbon steel or stainless steel, and has good sealing and connection strength. The carbon steel docking ring has high strength and toughness and can withstand a certain amount of pressure and impact. Its surface can be treated with rust prevention. The inside of the docking ring 6 is fixedly connected to multiple connecting shafts 7. The connecting shaft 7 serves as a component that supports the rotating plate 8 and enables it to rotate. The material of the connecting shaft 7 is generally metal, such as stainless steel or alloy steel, and has high strength and rigidity. The external rotation of the connecting shaft 7 is connected to the rotating plate 8. The rotating plate 8 is a rotatable component in the docking mechanism. The material of the metal plate or metal rod is generally metal, and has a certain strength and flexibility.

[0038] The shape of the rotating plate 8 is typically elongated or curved, with its length determined by the dimensions of the docking ring 6 and the layout of the latching rod 9. The latching rod 9 is fixedly attached to the exterior of the rotating plate 8. As a key component for securing the connection to the external pipe or equipment, the latching rod 9 is typically made of metal, such as stainless steel or alloy steel, for high strength and rigidity. The shape of the latching rod 9 is designed based on the shape of the connection interface to the external pipe or equipment, typically being elongated or block-shaped. Its dimensions are adapted to the connection interface, and its thickness is determined by the forces and strength requirements. The exterior of the rotating plate 8 is fixedly attached to the exterior of the rotating plate 8. The elastic assembly includes a telescopic rod 10. The telescopic rod 10, which provides telescopic function and support, is typically made of metal, such as stainless steel or aluminum alloy, for excellent strength and rigidity. The telescopic rod 10 typically consists of an inner rod and an outer rod. The inner rod flexibly extends and retracts within the outer rod, and the position of the rotating plate 8 is adjusted by adjusting the length of the inner rod extending from the outer rod. A spring 11 is sheathed around the exterior of the telescopic rod 10, providing both elastic force and return to the original position. Spring 11 is made of high-quality spring steel. Its elastic coefficient is precisely calculated and designed based on factors such as the required rotational force of rotating plate 8, the operating force for connection and removal, and the required reset effect. This ensures that it provides just the right amount of elastic support for rotating plate 8 under various operating conditions. The outer portion of telescopic rod 10 is fixedly connected to the exterior of rotating plate 8, and the outer portion of connecting block 5 is fixedly connected to the exterior of compressor body 4.

[0039] Reference Figures 3 and 4, the outside of the fixed rod 17 is fixedly connected with a rubber pad 22. The rubber pad 22 serves as a buffer and protective component. Its material is selected from high-quality rubber material with good flexibility, elasticity and wear resistance. The shape of the rubber pad 22 is generally designed to be a ring or long strip that matches the shape of the fixed rod 17. Its thickness is determined according to the required buffering effect and the size of the fixed rod 17. The top of the fixed rod 17 is fixedly connected with a threaded disk 23. The threaded disk 23 is an important structure for connecting and fixing related components. Its material is generally metal, such as stainless steel or alloy steel, with high strength and rigidity. The outside of the docking ring 6 is fixedly connected with a docking pipe 12. The docking pipe 12 serves as a pipeline component connecting the docking ring 6 and the oil-gas separator 15. Its material is generally selected from metal, such as stainless steel or carbon steel, with good sealing and pressure resistance;

[0040] The other end of the butt joint 12 is fixedly connected to the outside of the oil-gas separator 15, the outside of the rotating plate 8 is rotatably connected to the outside of the docking ring 6, the outside of the clamping rod 9 is rotatably connected to the outside of the docking ring 6, one end of the spring 11 is fixedly connected to the outside of the rotating plate 8, and the other end of the spring 11 is fixedly connected to the outside of the docking ring 6. When the device is not connected to an external pipeline or device, the spring 11 is in a natural state or pre-compressed state, providing a certain initial position and rotational torque for the rotating plate 8, facilitating the operator's connection operation. When the rotating plate 8 is connected or disassembled under the action of external force, the spring 11 will be compressed or stretched accordingly, storing or releasing elastic potential energy, thereby assisting the connection, resetting, and maintaining the stability of the connection, making the operation of the docking mechanism more convenient, flexible, and reliable, and ensuring a tight and safe connection between the air compressor and the external system.

[0041] Working Principle: First, the mounting box 1 serves as the external protection and support structure of the air compressor, providing the necessary stability. The air compressor body 4 is fixed to the base. The base 2 is made of cast iron or alloy steel, which has excellent shock absorption properties and can effectively reduce the impact of vibration generated during operation on the equipment.

[0042] Inside the air compressor body 4, the screw rotor rotates, driven by a motor, compressing the air. During the compression process, air is drawn in and compressed by the screw rotor, forming high-pressure gas. The compressed air is then connected to the oil-gas separator 15 via a docking mechanism. The oil-gas separator 15 separates oil droplets and moisture from the compressed air, ensuring the quality of the output air. Made of stainless steel or carbon steel, the oil-gas separator 15 is corrosion-resistant and adaptable to complex operating environments.

[0043] During air compressor operation, heat generated is effectively dissipated through a heat dissipation mechanism. This mechanism consists of a rotating plate 16, a fixed rod 17, a clamping plate 18, and a condenser 19. The condenser 19, as a core component, rapidly transfers heat through its excellent thermal conductivity. A protective cover 20 is installed at the bottom of the condenser 19, and multiple fan blades 21 are installed inside. These blades 21 rotate to generate airflow, promoting heat dissipation.

[0044] Furthermore, the air compressor's docking mechanism connects to external pipes or equipment via a connecting block 5 and a docking ring 6. The docking ring 6 is connected to a docking pipe 12, ensuring smooth delivery of compressed air to the external system. When no external pipe is connected, the spring 11 of the elastic assembly is in its natural state, providing an initial position and rotational torque to facilitate the operator's connection. When rotating plate 18 is subjected to external forces during connection or removal, spring 11 compresses or stretches accordingly, storing or releasing elastic potential energy, thereby assisting in connection, resetting, and maintaining connection stability.

[0045] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments or to make equivalent replacements for some of the technical features therein.
