Description

Technical Field

[0001] This utility model relates to the field of compressor technology, and in particular to an oil-free air compressor that facilitates heat dissipation. Background Technology

[0002] An oil-free air compressor is a compression device that does not require lubricating oil to participate in the compression process. By adopting oil-free lubrication technology or using special materials such as wear-resistant coatings and composite bearings, it solves the air pollution problem caused by lubricating oil in traditional compressors, thereby outputting clean, oil-free compressed air. It is widely used in industries with extremely high air quality requirements, such as medical, food, electronics, and pharmaceutical industries.

[0003] When traditional reciprocating air compressors operate under high loads, the sealing cap at the top of the compression chamber is subjected to direct impact from high-temperature and high-pressure gas for a long time, which easily accumulates heat. This causes the temperature of the sealing cap to rise continuously, which in turn drives up the temperature of the entire compression chamber. This not only accelerates the aging of the sealing material and causes leakage risks, but also affects compression efficiency and equipment stability. Utility Model Content

[0004] The purpose of this invention is to solve the problem of excessively high end cover temperature in existing air compressors.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an oil-free air compressor for easy heat dissipation, comprising an air compressor body, and further comprising: an air tank, wherein the air compressor body is fixedly installed on the upper part of the air tank, and the output end of the air compressor body is in communication with the air tank; a fan, wherein the end cover of the air compressor body is integrally formed with fins, the fan is rotatably installed on the upper part of the fins, and the air outlet of the fins is located on one side of the fins; in use, the fan transmits fresh air to the heat dissipation channel between the fins and discharges it through the outlet on one side of the fins.

[0006] In at least some embodiments, a cover plate is fixedly mounted on the upper part of the fin, and the fan is rotatably mounted on the upper part of the cover plate.

[0007] In at least some embodiments, a transmission assembly is also provided on one side of the air compressor body, the transmission assembly including a first wheel fixed to one end of the drive shaft of the air compressor body.

[0008] In at least some embodiments, two cover plates are fixedly installed on the upper part of each air compressor body, and a rotating rod is rotatably installed on the upper part of the two cover plates. A second rotating wheel is fixedly connected to both ends of the rotating rod, and the second rotating wheel is driven by the first rotating wheel through a transmission belt.

[0009] In at least some embodiments, a bevel gear is fixedly connected to the outside of the rotating rod, and the bevel gear meshes with a toothed groove formed on the upper part of the fan; when the air compressor body operates at variable speed, it drives the fan to rotate at a variable speed at a corresponding rate.

[0010] In at least some embodiments, two rollers are rotatably mounted on the lower part of the gas tank, a pull rod is fixedly mounted on the front part of the gas tank, a pressure gauge is fixedly mounted on the upper part of the gas pipe fixed on the upper part of the gas tank for real-time detection of the internal gas pressure of the gas tank, and a support frame is fixedly mounted on the lower part of the side of the gas tank away from the rollers.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0012] Compared with the traditional heat dissipation structure of the air compressor sealing cover, this device forms a three-dimensional air cooling system by directly molding fins on the outside of the sealing cover and cooperating with a fan. This allows the heat from the sealing cover and its surrounding high-heat areas to be released quickly, avoiding problems such as component thermal expansion and deformation and seal failure caused by local overheating, and effectively extending the service life of the whole machine. The fan and fins work together to form a stable air duct, allowing the cooling airflow to cover the key temperature area of ​​the sealing cover, improving the efficiency of heat conduction and air convection.

[0013] Meanwhile, as a one-piece molded structure, the fins do not require additional heat-conducting components, simplifying the structure and reducing assembly difficulty and maintenance costs.

[0014] The fan has a compact structure, is installed on the top without taking up extra space, and is highly adaptable. In addition, with the gas tank storage function, it can achieve stable output of compression efficiency, ensuring that the compressed gas is clean, oil-free and at a suitable temperature. It is especially suitable for medical, food or experimental environments with high requirements for thermal control performance and air purity. It is a high-efficiency oil-free compressor heat dissipation solution with optimized structure, reliable operation and convenient maintenance. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Implementation examples, based on Figures 1-4 As shown in the figure, the present invention provides an oil-free air compressor that facilitates heat dissipation. By integrally forming a fin plate 11 at the end cover of the oil-free air compressor body, and rotatably installing a fan 3 on its upper part, the forced airflow generated by the fan 3 during operation is used to introduce fresh air from above the fin plate 11 into the heat dissipation channel between the fin plate 11. During the airflow through the channel, the compression heat conducted by the end cover and the sealing cover is effectively carried away, so that the high temperature area is quickly cooled.

[0024] Specifically, the compressor body 2 includes: an air tank 1, with the compressor body 2 fixedly installed on the upper part of the air tank 1 and the output end of the compressor body 2 communicating with the air tank 1; and a fan 3, with fins 11 integrally formed on the end cover of the compressor body 2, and the fan 3 rotatably installed on the upper part of the fins 11, with the air outlet of the fins 11 located on one side of the fins 11; in use, the fan 3 transmits fresh air to the heat dissipation channel between the fins 11 and discharges it through the outlet on one side of the fins 11.

[0025] The airflow is discharged from the air outlet on one side of the fin 11, forming continuous forced convection, which avoids heat accumulation inside the cavity. This structure cleverly utilizes the thermal conductivity of the fin 11 and the airflow organization capability of the fan 3 to achieve concentrated heat dissipation of the high-temperature sealing cover area of ​​the air compressor, effectively reducing the temperature of the compression cavity, preventing structural expansion and seal aging caused by temperature rise, improving compression efficiency and operational stability, and storing and buffering the compressed air through the air tank 1, further enhancing the overall operational reliability and cooling uniformity of the system. It is suitable for oil-free compressor cooling systems in high-temperature continuous operation environments.

[0026] In this embodiment, a cover plate 8 is fixedly installed on the upper part of the fin plate 11, and the fan 3 is rotatably installed on the upper part of the cover plate 8. A transmission assembly 4 is also provided on one side of the air compressor body 2. The transmission assembly 4 includes a first rotating wheel 401 fixedly installed on one end of the drive shaft of the air compressor body 2. Two cover plates 8 are fixedly installed on the upper part of each air compressor body 2. A rotating rod 404 is rotatably installed on the upper part of the two cover plates 8. A second rotating wheel 403 is fixedly connected to both ends of the rotating rod 404. The second rotating wheel 403 is driven by the first rotating wheel 401 through the transmission belt 402. A bevel gear 405 is fixedly connected to the outside of the rotating rod 404. The bevel gear 405 is meshed with the tooth groove 406 opened on the upper part of the fan 3. When the air compressor body 2 is working at a variable speed, the fan 3 is driven to rotate at a variable speed.

[0027] By setting a cover plate 8 above the oil-free air compressor body, and rotatably mounting a fan 3 and a transmission assembly 4 on the upper part of the cover plate 8, the fan 3 can rotate synchronously with the compressor to achieve dynamic heat dissipation adjustment.

[0028] Specifically, the transmission assembly 4 includes a first rotating wheel 401 mounted on the drive shaft of the air compressor body 2. The first rotating wheel 401 is connected to the second rotating wheels 403 on the upper part of the two cover plates 8 via a transmission belt 402. The two second rotating wheels 403 are respectively fixed at both ends of the transverse rotating rod 404, driving the rotating rod 404 to rotate.

[0029] A bevel gear 405 is fixed to the outside of the rotating rod 404. The bevel gear 405 meshes with the tooth groove 406 on the upper part of the fan 3. When the air compressor drive shaft is running, the first rotating wheel 401 drives the second rotating wheel 403 to rotate, which in turn drives the rotating rod 404 to rotate, so that the bevel gear 405 drives the fan 3 to rotate synchronously.

[0030] Because the transmission is a mechanical linkage structure, the speed of fan 3 can change synchronously with the operating status of the compressor: when the compressor runs at a high speed and generates more heat, fan 3 accelerates synchronously to enhance heat dissipation efficiency.

[0031] When the compressor is running at low speed, the fan speed is reduced to reduce energy consumption and noise.

[0032] This structure enables automatic variable speed cooling without an electrically controlled fan, effectively adapting to thermal management needs under different operating conditions and improving system stability and intelligent heat dissipation capabilities.

[0033] In this embodiment, two rollers 6 are rotatably installed on the lower part of the gas tank 1, a pull rod 5 is fixedly installed on the front of the gas tank 1, a pressure gauge 10 is fixedly installed on the upper part of the gas pipe 9 fixed on the upper part of the gas tank 1 for real-time detection of the internal air pressure of the gas tank 1, and a support frame 7 is fixedly installed on the lower part of the side of the gas tank 1 away from the rollers 6.

[0034] By setting two rollers 6 at the bottom of the gas tank 1 and a fixed pull rod 5 at the front, the entire machine can be made portable and mobile, making it easy for users to move it flexibly between different work sites. When it needs to be moved, the pull rod 5 can be pulled to drive the rollers 6 to roll, thereby achieving a smooth transfer of the entire compressor system and improving ease of use.

[0035] The upper part of the gas tank 1 is equipped with a pressure gauge 10 to monitor the internal gas pressure status of the gas tank 1 in real time, so that users can keep track of the gas storage status and make operational adjustments, ensuring gas safety and stable system operation.

[0036] A support frame 7 is installed on the lower part of the side of the gas tank 1 away from the roller 6. This frame forms a stable three-point support structure when the equipment is stationary, effectively preventing the equipment from tipping over or slipping, and improving the safety and reliability of operation. The overall structure combines mobility and safety, making it suitable for compressor operation needs in various scenarios.

[0037] The working principle of this utility model is as follows: A finned plate 11 is integrally formed at the end cover of the oil-free air compressor body, and a fan 3 is rotatably installed on its upper part. The forced airflow generated by the fan 3 during operation draws fresh air from above the finned plate 11 into the heat dissipation channel between the finned plates 11. During the airflow through the channel, the compressed heat conducted from the end cover and sealing cover is effectively carried away, allowing for rapid cooling of the high-temperature area. Simultaneously, the airflow is discharged from the air outlet on one side of the finned plate 11, forming continuous forced convection and preventing heat accumulation inside the cavity. This structure cleverly utilizes the thermal conductivity of the finned plate 11 and the airflow organization capability of the fan 3 to achieve concentrated heat dissipation in the high-temperature sealing cover area of ​​the air compressor, effectively reducing the temperature of the compression cavity, preventing structural expansion and seal aging caused by temperature rise, improving compression efficiency and operational stability, and further enhancing the overall operational reliability and cooling uniformity of the system by connecting the air tank 1 to store and buffer the compressed air.

[0038] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
