At the same time, the rubber pads fixedly connected on both sides of the partition plate reduce the heat transfer between different areas, thereby preventing excessive heat accumulation, improving the overall heat dissipation efficiency, and providing a strong guarantee for the stable and efficient operation of electronic equipment.

[0024] Furthermore, the partition plate 302 has a connecting hole, and one end of the heat dissipation pipe 5 is fixedly connected to the inside of the connecting hole, and the other end of the heat dissipation pipe 5 is fixedly connected to the fan 6. One end of the heat dissipation pipe is firmly fixed inside the connecting hole, ensuring its stability and reliability, which not only simplifies the installation process, but also reduces the risk of loosening or damage due to vibration or impact.

[0025] Furthermore, ventilation holes are provided on the upper connecting plate 301, and the ventilation holes are evenly distributed in an array. Sliding grooves are provided on both sides of the ventilation holes, and the sliding grooves are slidably connected to the sliding blocks 7. The upper connecting plate 301 is located above the partition plate 302. The ventilation holes are provided on the upper connecting plate, which effectively increases the heat dissipation area and allows more air to flow through, thereby enhancing the convection dissipation of heat. Sliding grooves are provided on both sides of the ventilation holes. The movement of the sliding blocks in the sliding grooves can easily adjust the installation position, which is convenient for equipment maintenance and upgrading, and also provides greater flexibility for the installation and layout of other internal components.

[0026] Furthermore, a lower connecting plate 303 is provided below the upper connecting plate 301, and the lower connecting plate 303 is provided with a connecting groove for fixedly connecting the heat dissipation branch pipe 5, and air holes evenly distributed in an array are provided on one side of the connecting groove, and sliding grooves are provided on both sides of the air holes, and the sliding grooves are slidably connected to the sliding blocks 7, and the buffer brackets 4 are fixedly connected at both ends of the lower connecting plate 303. Through the lower connecting plate, the heat dissipation area is effectively increased, allowing more air to flow through, thereby enhancing the convection dissipation of heat, and sliding grooves are provided on both sides of the air holes. The movement of the sliding block in the sliding grooves can easily adjust the installation position, and the fixed connection buffer bracket below can reduce the impact of vibration and impact generated by the equipment during operation on the heat dissipation system.

[0027] Furthermore, the buffer bracket 4 includes a lower fixed bracket 401, and three springs 402 are provided on the sliding rod of the lower fixed bracket 401. The spring 402 is tightly pressed against the bottom surface of the upper fixed bracket 403, and one end of the upper fixed bracket 403 is fixedly connected to the bottom surface of the lower connecting plate 303.

[0028] Furthermore, the heat dissipation branch pipe 5 is composed of a main pipe 501 and a branch pipe 502. One end of the main pipe 501 is fixedly connected to the fan 6, and the other end of the main pipe 501 is fixedly connected to the lower connecting plate 303. One end of the branch pipe 502 passes through the lower connecting plate 303 and is fixedly connected to the partition plate 302. The heat dissipation branch pipe is composed of the main pipe and the branch pipe. The forced convection generated by the fan can directly act on the main pipe, and the cold air is quickly introduced through the cooperation of the main pipe and the branch pipe. The heat dissipation branch pipe can quickly send the airflow to the required internal part, and then the heat is exported and dissipated to the external environment, effectively reducing the working temperature of the equipment.

[0029] Furthermore, the sealing cover 2 is provided with a plurality of inclined grooves for heat dissipation, and the inclined grooves are inclined at an angle of 45 degrees. The inclined grooves of the sealing cover help prevent external pollutants such as dust and moisture from entering the interior of the device.

[0030] Furthermore, one end of the sealing cover 3 is snap-fitted to the top of the shell 1, and the other end of the sealing cover 3 is fixedly connected to the bottom of the shell 1.

[0031] Furthermore, a plurality of inclined grooves for heat dissipation are provided on the other side of the housing 1, and the inclined grooves are inclined at an angle of 45 degrees. The inclined grooves of the housing help prevent external pollutants such as dust and moisture from entering the interior of the device. Since the grooves are inclined, it is difficult for external liquid to flow into the interior of the device along the grooves under the action of gravity, thereby improving the protection level and reliability of the device.

[0032] Embodiment 2

[0033] See also Figure 1-Figure 4 A digital power converter shown in the figure includes a housing 1, a sealing cover 2 is provided on one side of the housing 1, a bearing plate 3 is provided inside the housing 1, buffer brackets 4 are provided at both ends of the bottom surface of the bearing plate 3, a heat dissipation branch pipe 5 is provided inside the buffer bracket 4, a fan 6 is provided on one side of the heat dissipation branch pipe 5, sliding blocks 7 are provided on the upper and lower surfaces of the bearing plate 3, and a limit block 8 is provided inside the sliding block 7. The bearing plate 3 is composed of an upper connecting plate 301, a partition plate 302, a lower connecting plate 303 and a rubber pad 304. The rubber pads 304 are fixedly connected on both sides of the partition plate 302, and are composed of a heat dissipation branch pipe, a fan, and inclined grooves on the housing and the sealing cover. When the fan is working, cold air is sucked in through the main pipe, and the cold air is distributed to various parts of the device through the branch pipe. At the same time, the heat is dissipated to the external environment through the air holes on the bearing plate and the inclined grooves on the housing and the sealing cover.

[0034] Furthermore, the partition plate 302 has a connecting hole, and one end of the heat dissipation pipe 5 is fixedly connected to the inside of the connecting hole, and the other end of the heat dissipation pipe 5 is fixedly connected to the fan 6. One end of the heat dissipation pipe is firmly fixed inside the connecting hole, ensuring its stability and reliability, which not only simplifies the installation process, but also reduces the risk of loosening or damage due to vibration or impact.

[0035] Furthermore, the upper connecting plate 301 is provided with ventilation holes, which are evenly distributed in an array, and sliding grooves are provided on both sides of the ventilation holes, which are slidably connected to the sliding blocks 7. The upper connecting plate 301 is located above the partition plate 302. The upper connecting plate is located above the partition plate, so that the upper connecting plate plays a more important role in heat dissipation. The partition plate divides the interior of the device into different functional areas, and the upper connecting plate serves as a heat dissipation channel, which effectively dissipates the heat of the upper area through the ventilation holes, thereby maintaining the temperature balance inside the entire device.

[0036] Furthermore, a lower connecting plate 303 is provided below the upper connecting plate 301. The lower connecting plate 303 has a connecting groove for fixedly connecting the heat dissipation branch pipe 5. One side of the connecting groove has air holes evenly distributed in an array. Both sides of the air holes have sliding grooves, which are slidably connected to the sliding blocks 7. The two ends of the lower connecting plate 303 are fixedly connected to the buffer bracket 4. The lower connecting plate is located below the upper connecting plate. The two cooperate with each other to form a stable load-bearing and heat dissipation structure. The lower connecting plate has a connecting groove for fixedly connecting the heat dissipation branch pipe. This design enables the heat dissipation branch pipe to be firmly installed on the lower connecting plate, ensuring the stability and reliability of the heat dissipation system.

[0037] Furthermore, the buffer bracket 4 includes a lower fixed bracket 401, and three springs 402 are provided on the sliding rod of the lower fixed bracket 401. The springs 402 are tightly pressed against the bottom surface of the upper fixed bracket 403, and one end of the upper fixed bracket 403 is fixedly connected to the bottom surface of the lower connecting plate 303. The optimized design of the buffer bracket also brings the following beneficial effects: First, the seismic performance of the equipment is improved, and the risk of equipment failure or damage due to vibration or impact is reduced; second, the supporting role of the buffer bracket; third, the installation and maintenance process of the equipment is simplified, and the sliding connection method of the buffer bracket makes the disassembly and assembly of the equipment more convenient and quick.

[0038] Furthermore, the heat dissipation branch pipe 5 is composed of a main pipe 501 and a branch pipe 502. One end of the main pipe 501 is fixedly connected to the fan 6, and the other end of the main pipe 501 is fixedly connected to the lower connecting plate 303. One end of the branch pipe 502 passes through the lower connecting plate 303 and is fixedly connected to the partition plate 302. The heat dissipation branch pipe is composed of a main pipe and a branch pipe. The main pipe serves as the main heat conduction channel, one end of which is fixedly connected to the fan, and the other end is fixedly connected to the lower connecting plate. The forced convection generated by the fan can directly act on the main pipe, quickly introducing cold air into the heat dissipation system, and at the same time, the main pipe also takes away the absorbed heat through the wind flow, thereby achieving efficient heat dissipation.

[0039] Furthermore, the sealing cover 2 is provided with a plurality of inclined grooves for heat dissipation, and the inclined grooves have an inclination angle of 45 degrees. The inclination angle of 45 degrees also helps to reduce the reflection of light on the surface of the sealing cover, making the device more visually beautiful and low-key.

[0040] Furthermore, one end of the sealing cover 3 is snap-fitted to the top of the housing 1, and the other end of the sealing cover 3 is fixedly connected to the bottom of the housing 1. The snap-fit ​​design of one end of the sealing cover makes the installation process simple and efficient. The snap-fit ​​is a fast and reliable connection method, which can firmly fix the sealing cover to the top of the housing to ensure a tight fit between the two. This design not only improves production efficiency, but also reduces installation costs, and provides convenience for the assembly of the equipment.

[0041] Furthermore, a plurality of inclined grooves for heat dissipation are opened on the other side of the shell 1, and the inclined angle of the inclined grooves is 45 degrees. By opening a plurality of heat dissipation grooves with an inclined angle of 45 degrees on the other side of the shell, this angle can effectively increase the heat dissipation area and improve the efficiency of heat transfer.

[0042] In this solution, the working process is: first, one end of the main pipe of the heat dissipation branch pipe is fixedly connected to the fan, and the other end is fixedly connected to the lower connecting plate. Then, one end of the branch pipe passes through the lower connecting plate and is fixedly connected to the partition plate.

[0043] Next, the lower fixed support of the buffer support is placed at a predetermined position, three springs are then installed on the sliding rod, and the upper fixed support is tightly pressed onto the springs. Finally, one end of the upper fixed support is fixedly connected to the bottom surface of the lower connecting plate.

[0044] On this basis, place the bearing plate inside the shell, and ensure that the rubber pads on both sides of the partition plate fit tightly against the inner wall of the shell. Then, slide the sliding grooves on the upper and lower connecting plates and the sliding blocks.

[0045] Finally, snap one end of the sealing cover into place on the top of the housing, and secure the other end to the bottom of the housing, making sure that the inclined groove on the sealing cover is aligned with the inclined groove on the other side of the housing to ensure heat dissipation.
