[0015] 1. The heat dissipation box, with its highly thermally conductive plate structure, efficiently absorbs and transfers heat from the vacuum equipment. Combined with the air convection created by the exhaust fan, this significantly improves heat dissipation efficiency, effectively reducing equipment temperature, ensuring stable operation, and minimizing performance degradation and malfunction risks caused by overheating. The flexible connection methods between the plates and the detachable design of the connecting grooves and plates facilitate assembly and maintenance, reducing repair costs and difficulty. The sliding connection between the connecting plate and the base plate, and the movable connection between the bracket positioning plate and the base plate groove, provide flexibility in the spatial layout of the device, making it adaptable to various vacuum equipment. The robust internal structure of the heat dissipation box, along with the ingenious cooperation between the top plate and the connecting plates, and the ball bearing design, disperses stress, reduces wear, optimizes airflow, extends the device's service life, and improves overall heat dissipation performance and reliability.

[0016] 2. By setting up a bracket, which consists of two positioning plates and a support rod, a stable and reliable support is provided for the top plate. During installation, the movable connection between the bottom positioning plate of the bracket and the groove of the bottom plate not only makes the installation process more convenient and efficient, reducing manpower and time costs, but also allows for flexible adjustment of the bracket position within a certain range to adapt to different installation scenarios and needs, enhancing the adaptability of the entire device. Moreover, the ball bearing embedded at the upper end of one of the positioning plates contacts the bottom of the top plate. When the top plate is disassembled, the ball bearing can convert sliding friction into rolling friction, greatly reducing friction and reducing component wear. At the same time, it allows the top plate to flexibly adjust its posture, effectively dispersing stress, extending the service life of the bracket and related components, and further improving the overall stability and reliability of the device.

[0017] 3. In summary, this type of vacuum equipment air-cooled heat dissipation device, through the setting of heat dissipation box and support structure, etc., the heat dissipation box achieves efficient heat conduction with the connecting plate structure and achieves efficient heat dissipation in conjunction with the exhaust fan. Its flexible connection method facilitates assembly and maintenance and gives flexibility to the spatial layout. The stable internal design optimizes airflow and disperses stress, which effectively ensures stable operation of the equipment and extends the service life of the device. The support uses positioning plates and support rods to stably support the top plate. The ball bearings on the positioning plate reduce friction, reduce wear, flexibly adjust the posture and disperse stress when the top plate is disassembled. Both of these factors together improve the overall stability and reliability of the device. Attached Figure Description

[0024] The following will refer to the appendix in the embodiments of this utility model. Figures 1-5 The technical solutions in the embodiments of this utility model will be clearly and completely described.

[0025] Please see Figure 1-5In this embodiment of the present invention, a vacuum equipment air-cooled heat dissipation device includes: a base plate 1, a heat dissipation box 2 is provided on the upper end of the base plate 1, a top plate 3 is embedded inside the upper end of the heat dissipation box 2, two supports 4 are provided on one side of the heat dissipation box 2, and an exhaust fan 5 is embedded inside the top plate 3; the heat dissipation box 2 includes two connecting plates 1 201, 202 and 3 203, which are respectively installed between the two connecting plates 1 201; the supports 4 include two positioning plates 401 and a support rod 402, which are installed between the two positioning plates 401;

[0026] When using this device, the vacuum pump is placed inside the heat sink 2. The heat generated during operation is initially dissipated through the heat dissipation holes in the heat sink 2. Simultaneously, the exhaust fan 5 embedded in the top plate 3 inside the heat sink 2 starts working. As the exhaust fan 5 rotates, it draws air from one side of the heat sink 2. The air flows through various channels and component surfaces inside the heat sink 2. Since the heat sink 2 is composed of connecting plates 1 (201), 2 (202), and 3 (203), these plates have good thermal conductivity, transferring heat from the plates to the air in contact with them. Meanwhile, the positioning plate 401 and support rod 402 of the bracket 4 not only support the heat sink 2 but also absorb some heat due to their connection with the heat sink 2, exchanging heat with the surrounding air. Under the continuous action of the exhaust fan 5, hot air is continuously drawn out of the heat sink 2, while cool outside air continuously replenishes it, forming a continuous air convection cycle, thereby quickly dissipating the heat generated by the vacuum equipment. The heat is quickly dissipated into the surrounding environment, effectively reducing the temperature of the vacuum equipment and ensuring its stable operation. Through the active ventilation of the exhaust fan 5 and the reasonable structural design of the heat dissipation box 2, heat can be quickly carried out of the vacuum equipment system. Compared with natural heat dissipation, the heat dissipation efficiency is greatly improved, which can effectively prevent the equipment performance degradation and failure caused by heat accumulation. The base plate 1 provides a stable foundation support for the entire heat dissipation device. The connecting plate structure of the heat dissipation box 2 and the positioning plate 401 and support rod 402 of the bracket 4 cooperate with each other to ensure that the heat dissipation device can maintain the structural stability in various working environments. It is not easy to deform or be damaged by external factors such as vibration and collision, thus ensuring the continuous and effective performance of the heat dissipation function. In subsequent maintenance and operation, due to the universality and simplicity of the components, maintenance costs and energy consumption can also be reduced, resulting in a good cost-effectiveness ratio. This allows the vacuum pump to play a protective role while dissipating heat, effectively improving the stability of the vacuum pump.

[0027] In this embodiment of the utility model, two grooves 101 are provided on the upper end of the base plate 1, and the positioning plates 401 at the bottom of the two brackets 4 are embedded in the grooves 101, and the grooves 101 and the positioning plates 401 are movably connected; two sliding grooves 102 are provided on the upper end of the base plate 1, and sliders 204 are fixedly installed on the bottom of the two connecting plates 1 201, the sliders 204 are embedded in the sliding grooves 102, and the sliding grooves 102 and the sliders 204 are slidably connected; connecting grooves 205 are provided at both ends of the two connecting plates 1 201, and the structure of the two connecting plates 202 and 3 203 at both ends is the same as that of the connecting plates 1 201, and the positions of the connecting grooves 205 are corresponding, and connecting plates 206 are embedded in the two connecting grooves 205, and the connecting plates 206 and the connecting grooves 205 are detachably connected;

[0028] During the assembly of the heat dissipation device, the positioning plate 401 at the bottom of the bracket 4 slides into the groove 101 of the base plate 1. This movable connection allows the position of the bracket 4 to be adjusted within a certain range, making it easy to adapt to different installation scenarios and needs. This enables the bracket 4 to accurately support the top plate 3, making the top plate 3 more stable during disassembly. At the same time, the slider 204 at the bottom of the connecting plate 1 201 slides along the groove 102 of the base plate 1, ensuring that the connecting plate 1 201 is placed stably and accurately on the base plate 1. The connecting plate 202 and the connecting plate 3 203 are connected at their ends to the connecting plate 1 201. The groove 205 and the embedded connecting plate 206 are connected. Since the connecting plate 206 and the connecting groove 205 are detachably connected, the connecting plates can be easily and quickly assembled to form the heat dissipation box 2 during assembly. During the heat dissipation process, the exhaust fan 5 operates to make air flow in the heat dissipation box 2. The airflow carries away the heat from the surface of the components, thereby achieving heat dissipation. The flexible connection between the components helps to distribute and conduct heat evenly throughout the device. The movable connection between the groove 101 and the positioning plate 401 and the sliding connection between the slide groove 102 and the slider 204 greatly simplifies the connection between the bracket 4 and the connecting plate 201. The installation steps on the base plate 1 make the installation process more efficient and faster, reducing labor and time costs. At the same time, the detachable connection design of the connecting groove 205 and the connecting plate 206 facilitates the assembly of each connecting plate of the heat dissipation box 2 and the disassembly during later maintenance. For example, when a connecting plate fails and needs to be replaced, it can be easily removed from the connecting groove 205, replaced with a new connecting plate, and reinstalled without causing serious damage to the structure of the entire device. This facilitates equipment maintenance and upgrades. The structural design of movable and sliding connections gives the heat dissipation device flexibility in spatial layout. It can flexibly adjust the position of the bracket 4 and the connecting plate 201 according to the shape, size, and installation environment requirements of different vacuum equipment, ensuring that the heat dissipation device can be perfectly adapted to various equipment. This improves the versatility and application range of the heat dissipation device, and it can be widely used in the heat dissipation needs of various types and specifications of vacuum equipment. During the operation of the heat dissipation device, whether it is subjected to the vibration of the equipment itself or the interference of external environmental factors, the connection between the components can effectively disperse stress, maintain the integrity and stability of the structure, ensure the continuous and reliable operation of the heat dissipation function, and reduce the risk of heat dissipation efficiency reduction or equipment failure due to structural instability.

[0029] In this embodiment of the present invention, each of the two connecting plates 201 has a limiting groove 207 on its inner side. The upper end of the limiting groove 207 has an opening 208, and the opening 208 and the limiting groove 207 are interconnected. The top plate 3 has a limiting block 301 fixedly installed at both ends. The limiting block 301 can penetrate the opening 208 and be embedded in the limiting groove 207. The limiting block 301 and the limiting groove 207 are slidably connected. The upper end of the connecting plate 3 203 is U-shaped. The top plate 3 can be embedded in the upper end of the connecting plate 3 203, and the outer end of the connecting plate 3 203 is flush with the outer end of the top plate 3. A ball bearing 403 is embedded in the upper end of one of the positioning plates 401. The ball bearing 403 is rotatably connected to the positioning plate 401. The uppermost end of the ball bearing 403 is in contact with the bottom of the top plate 3.

[0030] When assembling the air-cooled heat dissipation device of the vacuum equipment, the limiting blocks 301 at both ends of the top plate 3 slide into the limiting groove 207 through the opening 208 at the upper end of the limiting groove 207 on the inner side of the connecting plate 1 201, thereby achieving the connection and positioning of the top plate 3 and the connecting plate 1 201. Since it is a sliding connection, the installation process is relatively smooth. At the same time, the top plate 3 can be embedded into the upper end of the connecting plate 3 203, which is U-shaped, to further stabilize the position of the top plate 3. When it is necessary to disassemble the top plate 3, simply pull the top plate 3, and the bottom of the top plate 3 will contact the positioning plate 4. The upper end of the ball bearing 403 contacts the top plate 401, allowing the ball bearing 403 to rotate freely on the positioning plate 401. This enables the top plate 3 to move or adjust its posture relatively flexibly when subjected to external forces from above or other directions, preventing damage to components due to excessive localized force. This makes disassembly of the device more flexible and convenient for workers. The sliding connection between the limiting block 301 and the limiting groove 207, along with the embedded fit between the top plate 3 and the connecting plate 203, makes the installation of the top plate 3 within the heat sink 2 structure more stable, effectively preventing… During equipment operation, factors such as vibration may cause the top plate 3 to loosen or shift, thus ensuring the integrity and stability of the entire heat dissipation device structure and ensuring the continuous and stable operation of the heat dissipation function. The ball bearing 403 can convert the sliding friction between the top plate 3 and the positioning plate 401 into rolling friction, which greatly reduces friction and reduces wear and energy loss caused by friction between components. At the same time, rolling friction allows the top plate 3 to adjust its position more smoothly within a certain range, effectively dispersing and alleviating stress caused by vibration, thermal expansion and contraction, etc., protecting the top plate 3 and other connected components from damage, and extending the service life of the heat dissipation device. The stable and reasonable structure of the top plate 3 helps to optimize the airflow channel inside the heat dissipation box 2, so that the air driven by the exhaust fan 5 can flow more efficiently in the heat dissipation box 2 along a predetermined path, evenly sweeping over the surface of each heat-generating component, avoiding airflow turbulence or local dead zones, improving the heat exchange efficiency between air and heat-generating components, and further improving the overall heat dissipation performance of the heat dissipation device.

[0031] Working Principle: When the air-cooled heat dissipation device of this vacuum equipment is working, the vacuum equipment located in the heat dissipation box 2 generates heat. A portion of the heat is first dissipated outwards through the heat dissipation holes of the heat dissipation box 2 for initial heat dissipation. At this time, the exhaust fan 5 installed inside the top plate 3 starts, forcefully drawing air from one side of the heat dissipation box 2. After the outside cold air is drawn into the heat dissipation box 2, as it flows through the various channels inside the heat dissipation box 2 formed by connecting plates 1 (201), 2 (202), and 3 (203) and the surfaces of the components, the heat is efficiently transferred from the plates to the air in contact with them due to the good thermal conductivity of these plates. During the installation process, the positioning plate 401 at the bottom of the bracket 4 slides into the groove 101 opened in the base plate 1. This movable connection method allows the position of the bracket 4 to be flexibly adjusted within a certain range to precisely support the top plate 3 and provide stability when the top plate 3 is disassembled. The slider 204 at the bottom of connecting plate 1 (201) slides along the groove 102 of the base plate 1. This ensures that connecting plate 1 201 can be placed stably and accurately on base plate 1. Connecting plate 202 and connecting plate 3 203 are connected by connecting grooves 205 at both ends corresponding to connecting plate 1 201 and connecting plates 206 embedded therein. Since the connecting plates 206 and connecting grooves 205 are detachably connected, the connecting plates can be easily and quickly assembled into heat dissipation box 2 during assembly. During disassembly, the bottom of top plate 3 contacts the ball bearings 403 at the top of positioning plate 401. The ball bearings 403 can rotate freely on positioning plate 401, converting sliding friction into rolling friction. This not only greatly reduces friction and reduces wear and energy loss caused by friction between components, but also allows top plate 3 to adjust its position more smoothly within a certain range, extending the service life of the heat dissipation device, improving the heat exchange efficiency between air and heat-generating components, and further enhancing the heat dissipation performance of the entire heat dissipation device, providing a strong guarantee for the stable operation of vacuum equipment.
