Description

Technical Field

[0001] The present invention relates to the technical field of power supply switch devices, and in particular to a power distribution cabinet with a multi-channel heat dissipation function. Background Art

[0002] Distribution cabinets are primarily used for power management and protection, providing various power output and protection measures to ensure safe and reliable system operation. They include functions such as power filtering, power conversion, and power recovery, enabling them to provide stable power output to equipment according to system requirements and manage and protect the power system. The output voltage and current of power distribution cabinets are relatively stable, primarily meeting the power needs of production and transmission equipment. Distribution cabinets typically house electrical equipment such as inverters, contactors, and relays, which generate heat during operation. If this heat is not dissipated promptly, the internal cabinet temperature will rise. Therefore, cooling fans and ventilation ducts are required to actively remove heat from the cabinet. Existing cabinets use multi-channel cooling. Multi-channel cooling increases the cooling area and airflow, dissipating heat more quickly and effectively reducing internal cabinet temperatures. However, multi-channel cooling can lead to concentrated airflow in some channels, while airflow in others is weak. This exposes channels with weak airflow to the external environment, allowing dust to enter the cooling channels. Accumulating on the channel walls, it forms an insulating layer, increasing heat transfer resistance and affecting the cabinet's cooling efficiency, resulting in uneven temperature distribution within the cabinet.

[0012] In the above technical solution, the technical effects and advantages provided by the present invention are:

[0013] 1. The present invention can guide the airflow inside the heat dissipation channel through the arrangement of the exhaust component, the heat dissipation channel and the radiator, thereby preventing the air from easily forming a stagnation zone in the heat dissipation channel under weak airflow. The rotation of the guide blades forces the airflow to flow, thereby preventing the occurrence of local airflow obstruction in the heat dissipation channel, reducing the adsorption of impurities inside the heat dissipation channel, avoiding poor heat dissipation caused by dust accumulation, and improving the heat dissipation effect of the cabinet;

[0014] 2. The present invention, through the arrangement of the reciprocating assembly, the guide vanes, the stabilizing sleeve, and the heat dissipation channel, can achieve a combined rotation and vertical movement of the guide vanes within the heat dissipation channel, causing the guide vanes to generate a stronger disturbance in the surrounding hot air flow. This disturbance disrupts the laminar flow of the hot air flow, making it easier for the hot air flow to mix with the surrounding air and forming turbulent flow that is conducive to discharge. In the turbulent state, the diffusion speed of the hot air flow is accelerated, and it can be more quickly directed to the exhaust port of the heat dissipation channel, thereby improving the hot air discharge capacity of the entire heat dissipation channel.

[0015] 3. The present invention provides guide vanes and heat dissipation channels. The movement of the guide vanes maintains a disturbance of the hot air in the heat dissipation channel. The turbulent airflow exerts a dynamic force, destroying the adhesion conditions between dust and the heat dissipation channel surface, freeing dust from its attachment point. This allows the complex path of the disturbed airflow to cover all areas of the heat dissipation channel, preventing excessive accumulation of dust in a certain local location and improving the heat dissipation efficiency within the exhaust assembly.

[0016] 4. The present invention, through the arrangement of the air induction component, the heat dissipation channel and the induction blades, can realize the secondary circulation of the air flow in the heat dissipation channel. The reintroduced air flow will destroy the static air layer near the wall surface in the heat dissipation channel, promote the transfer of heat from the wall surface to the mainstream air flow, and the air flow can pass more quickly and smoothly, promptly removing the heat generated in the cabinet.

[0017] 5. The present invention provides an air duct, guide vanes, and heat dissipation channel. The airflow reintroduced into the heat dissipation channel by the air duct can maintain coordination with the guide vanes. The reintroduced airflow flushes dust from the heat dissipation channel and the guide vanes, reducing dust accumulation on the surfaces of the guide vanes and the heat dissipation channel and preventing dust from being adsorbed in the heat dissipation channel. Heat can be transferred more smoothly from the heat dissipation channel to the flowing air, thereby improving heat dissipation efficiency.

[0018] 6. The present invention realizes knocking at different positions in the stabilizing sleeve through the arrangement of the knocking component, the stabilizing sleeve, the guide blades and the heat dissipation channel, thereby generating vibrations in the stabilizing sleeve and the guide blades, which is used to disrupt the electrostatic field on the surface of the guide blades, reduce the adhesion of dust on the guide blades, reduce the adsorption of dust, increase the contact area between the airflow and the guide blades, and facilitate the rapid discharge of the airflow in the heat dissipation channel, so that the radiator can achieve the same heat dissipation effect at lower power, thereby reducing the energy consumption of the entire cabinet and reducing operating costs.

[0039] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0040] The present invention provides Figure 1 、 Figure 2 and Figure 3The heat dissipation device 10 is a heat dissipation device 10 for discharging heat from the heat sink 1 to the heat sink 13. The heat dissipation device 10 is a heat dissipation device 10 for discharging heat from the heat sink 1 to the heat sink 13. The heat dissipation device 10 is a heat dissipation device 10 for discharging heat from the heat sink 1 to the heat sink 13.

[0041] In addition, the specific structure and principle of the radiator 12 are all prior art, so they are not described in detail in this application. Currently, during the heat dissipation process of the cabinet 1, the heat absorption process of the radiator 12 generally includes the following steps:

[0042] 1. Blades: responsible for promoting air flow, usually adopting axial flow or centrifugal design;

[0043] 2. Motor: drives the blades to rotate, guides the direction of airflow, and ensures that air is discharged from the designated path. It can be an AC motor, DC motor or brushless motor;

[0044] 3. Frame: supports the blades and motor, usually made of plastic or metal, often installed on the top, side or bottom of the cabinet to discharge the heated hot air.

[0045] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, the exhaust assembly 2 includes a rotating column 25 rotatably connected to the radiator 12 and a stabilizing sleeve 21 rotatably connected to the heat dissipation channel 13. The exterior of the stabilizing sleeve 21 is fixedly connected to a plurality of guide vanes 22, and the guide vanes 22 are configured as a meandering willow-leaf structure. The exterior of the guide vanes 22 is provided with a plurality of through holes 23 for guiding airflow. The bottom end of the rotating column 25 is fixedly connected to a guide column 24, and the stabilizing sleeve 21 is movably sleeved on the exterior of the guide column 24.

[0046] In addition, when the airflow contacts the guide blades 22, the airflow moves along the surface of the guide blades 22, and part of the airflow on the surface of the guide blades 22 passes through the through holes 23, causing the airflow to be stratified near the guide blades 22, thereby increasing the residence time of the airflow in the heat dissipation channel 13. During this process, the rotation of the guide blades 22 has a certain cleaning effect on the heat dissipation channel 13, so that the guide blades 22 can allow the airflow more time to blow away the dust in the heat dissipation channel 13, reducing the accumulation of dust in the heat dissipation channel 13 and avoiding the occurrence of a decrease in heat dissipation efficiency due to dust coverage.

[0047] refer to Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown, when it is necessary to discharge the hot air in the cabinet 1 to the outside, the rotating column 25 is first connected to the output end of the radiator 12, so that the radiator 12 rotates to absorb the hot air inside the cabinet 1 and transports the absorbed hot air to the inside of the heat dissipation channel 13. In the process of rotation, the output end of the radiator 12 drives the rotating column 25 to rotate synchronously, and the rotating column 25 rotates to drive the guide column 24 to rotate at the same time. Then the guide column 24 rotates to drive the stabilizing sleeve 21 to move synchronously. At this time, the rotation of the stabilizing sleeve 21 drives a plurality of guide blades 22 to rotate synchronously, and the guide blades 22 rotate the heat dissipation channel 13. The hot air from the outside is guided, and the guide blades 22 themselves can extend the path of the hot air, so that the hot air can maintain full contact with the guide blades 22, preventing the air from easily forming a stagnation area in the heat dissipation channel 13 under weak airflow. The rotation of the guide blades 22 forces the airflow to flow, breaking this stagnation state, ensuring that the airflow is guided and moved in the heat dissipation channel 13, preventing the occurrence of local airflow obstruction, ensuring that the airflow distribution in the heat dissipation channel 13 is more reasonable, reducing impurities from entering the heat dissipation channel 13, avoiding poor heat dissipation due to dust accumulation, and improving the heat dissipation effect of the cabinet 1.

[0048] refer to Figure 3 、 Figure 6 and Figure 7As shown, the reciprocating assembly 3 includes a stabilizing ring 35 installed in the stabilizing sleeve 21 and a flow limiting groove 34 opened on the outside of the guide column 24, and the stabilizing ring 35 is sleeved on the outside of the guide column 24, and the inside of the stabilizing ring 35 is connected to the diversion block 36, and the diversion block 36 is slidably connected to the flow limiting groove 34; the reciprocating assembly 3 also includes a fixed ring 31 fixedly connected to the bottom of the plurality of diversion blades 22 and a push ring 32 installed in the heat dissipation channel 13, and the top of the push ring 32 is set to an inclined ring, and the bottom end of the fixed ring 31 is installed There is a push post 33, and the bottom end of the push post 33 is attached to the top end of the push ring 32. The push ring 32 is used to push the push post 33 to move upward or downward along the heat dissipation channel 13. A knocking component 5 is connected between the bottom end of the guide post 24 and the stabilizing sleeve 21. The knocking component 5 is used to clean dust on the stabilizing sleeve 21 and the guide vane 22. A tightening component 4 is provided between the push ring 32 and the radiator 12, and the tightening component 4 is used to adjust the height of the guide vane 22 in the heat dissipation channel 13 upward or downward;

[0049] In addition, the movement of the guide blades 22 keeps disturbing the hot air in the heat dissipation channel 13. The turbulent airflow exerts a dynamic force, destroying the adhesion conditions between the dust and the surface of the heat dissipation channel 13, and separating the dust from the attachment point. This allows the complex path of the disturbed airflow to cover all areas of the heat dissipation channel 13, preventing excessive accumulation of dust in a certain local location. In addition, the hot air discharged from the heat dissipation channel 13 can reduce the stickiness of some dust particles, making them easier to remove, thereby improving the heat dissipation efficiency in the cabinet 1.

[0050] refer to Figure 3 、 Figure 6 and Figure 7As shown, when the guide post 24 rotates, the stabilizing sleeve 21 drives the stabilizing sleeve 21 to rotate along the heat dissipation channel 13, and the rotation of the guide post 24 drives the flow limiting groove 34 to rotate synchronously. Then, the rotation of the flow limiting groove 34 drives the guide block 36 and the stabilizing ring 35 to rotate synchronously along the stabilizing sleeve 21, so that the stabilizing sleeve 21 rotates following the rotation of the guide post 24. At this time, the stabilizing sleeve 21 is in a rotating state in the heat dissipation channel 13. In this process, it is necessary to rotate the stabilizing sleeve 21 while driving the stabilizing sleeve 21 to move upward along the outside of the guide post 24. The rotation of the stabilizing sleeve 21 drives the guide blades 22 to rotate synchronously, and the rotation of the guide blades 22 drives the fixing ring 31 to rotate synchronously along the inside of the heat dissipation channel 13. Then, the rotation of the fixing ring 31 drives the push post 33 to move along the top end of the push ring 32. At this time, the push post 33 continuously moves upward along the top end of the push ring 32, so that the distance between the fixing ring 31 and the push ring 32 is continuously changed. At this time, the fixing ring 31 rotates along the heat dissipation channel 13 under the movement of the push post 33. The stabilizing sleeve 21 moves upward in the heat channel 13, and the fixing ring 31 moves downward to push the stabilizing sleeve 21 to move upward, and the upward-moving stabilizing sleeve 21 moves upward synchronously along the outside of the guide column 24, so that the upward movement of the stabilizing sleeve 21 drives the guide block 36 to move upward synchronously along the flow limiting groove 34, and then the stabilizing sleeve 21 not only realizes a rotational motion state in the heat dissipation channel 13, but also realizes upward movement along the heat dissipation channel 13 while rotating, so that the motion state of the guide blade 22 in the heat dissipation channel 13 can be flexibly adjusted; the guide blade 22 realizes a composite motion of rotation and up and down movement in the heat dissipation channel 13, so that the guide blade 22 produces a stronger disturbance to the surrounding hot air flow, which destroys the laminar state of the hot air flow, makes the hot air flow easier to mix with the surrounding air, and forms turbulence that is conducive to discharge, and in the turbulent state, the diffusion speed of the hot air flow is accelerated, and it can be more quickly guided to the exhaust port of the heat dissipation channel 13, thereby improving the hot air flow discharge capacity of the entire heat dissipation channel 13.

[0051] refer to Figure 11 and Figure 12As shown, the air induced component 6 includes an air induced pipe 61 connected between the radiator 12 and the heat dissipation channel 13 and two sealing sleeves 62 fixedly connected to the top of the heat dissipation channel 13 and communicating with the interior thereof, and the sealing sleeve 62 is used to adjust the length of the air induced pipe 61 in the heat dissipation channel 13, the outer part of the air induced pipe 61 is movably sleeved with a spiral sleeve 64, the inner part of the sealing sleeve 62 is fixedly connected with a support ring 66, and the support ring 66 is sleeved on the outer part of the air induced pipe 61, the top of the support ring 66 is fixedly connected with a plurality of eccentric soft plates 67, and the top of the eccentric soft plate 67 is connected with an elastic pad 68, and the sealing sleeve 62 The top of the spiral sleeve 64 is provided with an internal thread 65 for screwing into the spiral sleeve 64, and the interior of the spiral sleeve 64 is provided with a displacement groove 69 that cooperates with the elastic pad 68, and the displacement groove 69 is used to gather the elastic pad 68 to the outside of the air duct 61 and lock the air duct 61 in the sealing sleeve 62. The plug sleeve 63 is inserted and removed from the interior of the spiral sleeve 64; and the connection between the elastic pad 68 and the eccentric soft plate 67 maintains a flexible connection state, so that the elastic pad 68 can move along the top of the eccentric soft plate 67 in the direction of the force after being resisted, so that the elastic pad 68 and the eccentric soft plate 67 maintain good cooperation;

[0052] refer to Figure 11 and Figure 12 As shown, when it is necessary to adjust the length of the air duct 61 extending into the heat dissipation channel 13, the spiral sleeve 64 is rotated to keep it in screw engagement with the internal thread 65 opened in the sealing sleeve 62, and then the spiral sleeve 64 moves upward along the inside of the internal thread 65 under rotation. At this time, the movement of the spiral sleeve 64 drives the displacement groove 69 to move synchronously. At this time, the inside of the displacement groove 69 and the outside of the elastic pad 68 slowly lose the effect of interference, and the gap between the displacement groove 69 and the elastic pad 68 is constantly increasing during the movement, and the elastic pad The plate 68 is elastically reset, so that one side of the elastic pad 68 loses its lock with the outside of the air duct 61. As the air duct 61 is pushed, it is guided along the elastic pad 68, the sealing sleeve 62 and the eccentric soft plate 67, and the length of the air duct 61 inside the heat dissipation channel 13 is adjusted. Then, the length of the air duct 61 near the guide blade 22 is maintained at an appropriate length. After the position adjustment of the air duct 61 is completed, the above steps are reversed to achieve the re-locking of the air duct 61 in the sealing sleeve 62 and the heat dissipation channel 13.

[0053] refer to Figure 11 and Figure 12As shown, the two air ducts 61 are respectively located on both sides of the radiator 12 and the heat dissipation channel 13, and the two air ducts 61 can provide additional exhaust paths for the radiator 12 and the heat dissipation channel 13, disperse the airflow and guide the hot air to be discharged from different positions temporarily, which can promote the hot air and the air outside the air duct 61 to achieve internal and external interaction, and the two air ducts 61 will partially reintroduce the exhausted airflow into the heat dissipation channel 13 to form a secondary circulation. The reintroduced airflow will destroy the static air layer close to the wall of the airflow in the heat dissipation channel 13, and promote the heat transfer from the wall to the mainstream airflow. , the air flow can pass through more quickly and smoothly, and take away the heat generated in the cabinet 1 in time. In addition, the air flow reintroduced into the heat dissipation channel 13 by the air duct 61 can maintain coordinated cooperation with the guide blades 22. The reintroduced air flow will flush the dust in the heat dissipation channel 13 and the guide blades 22, reducing the accumulation of dust on the surfaces of the guide blades 22 and the heat dissipation channel 13, and preventing dust from being adsorbed in the heat dissipation channel 13. Heat can be transferred more smoothly from the heat dissipation channel 13 to the flowing air, thereby improving the heat dissipation efficiency and ensuring that the electrical equipment in the cabinet 1 operates in a suitable temperature environment.

[0054] refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown, the tension assembly 4 includes a connecting ring 41 fixedly connected to the bottom end of the radiator 12, an externally threaded ring 45 sleeved on the bottom of the push ring 32, and a threaded groove 46 provided in the heat dissipation channel 13 for the externally threaded ring 45 to be threadedly connected. A centering ring 44 is fixedly sleeved on the top end of the stabilizing sleeve 21, and a support spring 42 is fixedly connected to the bottom end of the connecting ring 41. The end of the support spring 42 close to the centering ring 44 is fixedly connected to a bottom ring frame 43, and the bottom ring frame 43 and the centering ring 44 are movably connected.

[0055] refer to Figure 3 、 Figure 4 、 Figure 5 and Figure 7As shown, when it is necessary to adjust the elastic tension between the guide blade 22 and the heat sink 12 in the heat dissipation channel 13, the push ring 32 is driven by rotating the push ring 32 to drive its outer portion and the external threaded ring 45 to rotate synchronously along the heat dissipation channel 13. Then, during the rotation of the external threaded ring 45, the threaded groove 46 is kept in screwing engagement, so that the push ring 32 moves downward along the heat dissipation channel 13. At this time, during the downward movement of the push ring 32, the elasticity of the support spring 42 itself gives a downward thrust to one end of the bottom ring frame 43, and the downward movement of the bottom ring frame 43 pushes the centering ring 44 to move synchronously, and during the movement of the centering ring 44, the guide blade 22 is pushed downward, so that the movement of the guide blade 22 pushes the fixing ring 31 to move synchronously, so that the push column 33 and the push ring 32 maintain stable contact, and then the support spring 42 elastically The elastic expansion and contraction is adjusted so that the tightness between the guide blade 22 and the radiator 12 is adjusted synchronously, ensuring that the guide blade 22 rotates flexibly. At the same time, the tightness between the guide blade 22 and the radiator 12 is adjusted to ensure that the guide blade 22 stably reciprocates upward or downward along the heat dissipation channel 13, so that the guide blade 22 and the air duct 61 maintain reciprocating alternating motion, which is conducive to maintaining the up and down alternating motion between the position of the guide blade 22 and the air duct 61, and can blow different positions on the outside of the guide blade 22, reducing the adsorption of dust on the surface of the guide blade 22, so that the guide blade 22 can clean the dust on the inner wall of the heat dissipation channel 13 in time, and can avoid the formation of a heat insulation layer due to dust accumulation in the heat dissipation channel 13, thereby reducing the heat transfer resistance and improving the heat dissipation efficiency of the cabinet 1.

[0056] refer to Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, the knocking assembly 5 includes a fixed plate 52 installed at the bottom end of the guide column 24 and two bumping plates 51 symmetrically connected to the stabilizing sleeve 21, the bottom end of the fixed plate 52 is slidably connected to two symmetrical knocking blocks 53, and the two knocking blocks 53 knock with the two bumping plates 51 respectively, and the bottom end of the fixed plate 52 is provided with a slide groove 56 for the two knocking blocks 53 to move, and a retraction box 54 is fixedly connected to the middle part of the slide groove 56, and the corresponding sides of the two knocking blocks 53 are fixedly connected to a sliding column 55, and one end of the two sliding columns 55 extends to the interior of the retraction box 54 and is connected to an ejection spring 57; the two bumping plates 51 are arranged in a wavy structure, and the wavy structures of the two bumping plates 51 are staggered, and the side of the two knocking blocks 53 close to the two bumping plates 51 is arranged in a conical structure;

[0057] In addition, the two bumping plates 51 cooperate with the two knocking blocks 53 so that the guide blade 22 is knocked at different positions inside the guide blade 22 during its upward movement. The continuous change of the knocking position will form irregular vibrations, which effectively prevents dust from accumulating on the guide blade 22, making it difficult for dust to adhere to the surface of the guide blade 22, reducing the maintenance workload and improving the flexibility of the entire heat dissipation. In addition, the knocking action causes the guide blade 22 to produce a small vibration, thereby changing the airflow path, ensuring that the airflow is evenly distributed in the heat dissipation channel 13, covering more areas, and facilitating the guidance and discharge of the airflow.

[0058] refer to Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, when the stabilizing sleeve 21 moves upward along the outside of the guide column 24, the two knocking blocks 53 maintain coordinated cooperation, and the upward movement of the stabilizing sleeve 21 drives the two bumping plates 51 to move upward synchronously, and then one of the bumping plates 51 conflicts with the knocking block 53 and pushes one of the knocking blocks 53 to move along the inside of the slide groove 56. At this time, one of the knocking blocks 53 moves to push one of the slide posts 55 to move along the inside of the contraction box 54, and one of the slide posts 55 pushes the ejection spring 57 to move. In this process, the other knocking block 53 conflicts with the other bumping plate 51, so that the ejection spring 57 is squeezed between the two slide posts 55. As one of the bumping plates 51 continues to move, one of the knocking blocks 53 slides over one side of one of the bumping plates 51 and moves to the recess of one of the bumping plates 51, and then the ejection spring 57 elastically stretches to give one end of one of the slide posts 55 Thrust, pushing one of the knocking blocks 53 to move along the slide groove 56 toward the recess of one of the bumping plates 51, and then one of the bumping plates 51 and the recess of one of the knocking blocks 53 form a knocking, generating vibration between the guide vane 22 and the stabilizing sleeve 21. Similarly, the other knocking block 53 and the recess of the other bumping plate 51 are knocked, and reciprocating in sequence, and alternating knocking is achieved between the two bumping plates 51 and the two fixed plates 52. Therefore, knocking is achieved at different positions in the stabilizing sleeve 21, thereby generating vibrations to the stabilizing sleeve 21 and the guide vane 22, which is used to disrupt the electrostatic field on the surface of the guide vane 22, reduce dust adhesion on the guide vane 22, reduce dust adsorption, increase the contact area between the airflow and the guide vane 22, and facilitate the rapid discharge of airflow in the heat dissipation channel 13, so that the radiator 12 can achieve the same heat dissipation effect at lower power, thereby reducing overall energy consumption and reducing operating costs.

[0059] Working principle:

[0060] When in use;

[0061] refer to Figure 1 、 Figure 2 and Figure 3 As shown, the heat generated inside the cabinet 1 is absorbed in time by the radiator 12, and then the radiator 12 transports the hot air absorbed in the cabinet 1 to the inside of the heat dissipation channel 13, and during the rotation process, the output end of the radiator 12 drives the rotating column 25 to rotate synchronously, and the rotation of the rotating column 25 drives the guide column 24 to rotate at the same time, and then the rotation of the guide column 24 drives the stabilizing sleeve 21 to move synchronously. At this time, the rotation of the stabilizing sleeve 21 drives several guide blades 22 to rotate synchronously, and the guide blades 22 guide the hot air inside the heat dissipation channel 13, and the guide blades 22 themselves can extend the path of the hot air, so that the hot air can maintain full contact with the guide blades 22, preventing the air from easily forming a stagnation area in the heat dissipation channel 13 under weak airflow. The rotation of the guide blades 22 forces the airflow to circulate, breaking this stagnation state, ensuring that the airflow is guided and moved in the heat dissipation channel 13, and preventing the occurrence of local airflow obstruction.

[0062] refer to Figure 3 、 Figure 6 and Figure 7 As shown, through the rotation of the guide blades 22 and the stabilizing sleeve 21, the guide blades 22 and the reciprocating assembly 3 cooperate with each other, and the guide blades 22 realize a compound motion of rotation and up and down movement in the heat dissipation channel 13, so that the guide blades 22 produce a stronger disturbance to the surrounding hot air flow. This disturbance destroys the laminar state of the hot air flow, makes the hot air flow easier to mix with the surrounding air, and forms turbulence that is conducive to discharge. In the turbulent state, the diffusion speed of the hot air flow is accelerated, and it can be guided to the exhaust port of the heat dissipation channel 13 more quickly, thereby improving the hot air flow discharge capacity of the entire heat dissipation channel 13.

[0063] refer to Figure 11 and Figure 12 As shown, when it is necessary to adjust the length of the air duct 61 and the position near the guide blade 22, the spiral sleeve 64 is rotated to keep it screwed together with the internal thread 65 opened in the sealing sleeve 62, and then the spiral sleeve 64 moves upward along the internal thread 65 under rotation. At this time, the movement of the spiral sleeve 64 drives the displacement groove 69 to move synchronously. At this time, the inside of the displacement groove 69 and the outside of the elastic pad 68 slowly lose the effect of interference, and the gap between the displacement groove 69 and the elastic pad 68 is constantly increasing during the movement, and the elastic pad 68 itself elastically resets, so that one side of the elastic pad 68 loses the lock with the outside of the air duct 61. As the air duct 61 is pushed, it is guided to move along the elastic pad 68, the sealing sleeve 62 and the eccentric soft plate 67, and the length of the air duct 61 inside the heat dissipation channel 13 is adjusted, and then the length of the air duct 61 is maintained at an appropriate length near the guide blade 22.

[0064] refer to Figure 6 、 Figure 8 、 Figure 9 、 Figure 10 and Figure 11 As shown, during the upward movement of the stabilizing sleeve 21 and the guide blades 22 along the heat dissipation channel 13, the knocking component 5 can knock on different positions in the stabilizing sleeve 21, thereby generating vibrations on the stabilizing sleeve 21 and the guide blades 22, which is used to disrupt the electrostatic field on the surface of the guide blades 22, reduce dust adhesion on the guide blades 22, reduce dust adsorption, increase the contact area between the airflow and the guide blades 22, and facilitate the rapid discharge of the airflow in the heat dissipation channel 13, so that the radiator 12 can achieve the same heat dissipation effect at lower power, thereby reducing the energy consumption of the entire cabinet 1 and reducing operating costs.
