Description

Technical Field

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

[0002] Distribution cabinets are mainly used for power management and protection, providing various power outputs and protection measures to ensure the safe and reliable operation of the system. It includes functions such as power filtering, power conversion, and power restoration, and can provide corresponding stable power outputs for devices according to the needs of the system, and manage and protect the power system. The output voltage and current of the power supply cabinet are relatively stable, mainly meeting the power requirements of production and transmission equipment. Electrical equipment such as frequency converters, contactors, and relays are usually installed in the distribution cabinet, and these devices generate heat during operation. If the heat cannot be dissipated in time, it will cause the temperature inside the cabinet to rise. Therefore, it is necessary to cooperate with a cooling fan and a ventilation duct to actively discharge the heat from the cabinet. The existing cabinets adopt multi-channel heat dissipation, and multi-channel heat dissipation can increase the heat dissipation area and air circulation volume, so that the heat can be dispersed faster, accelerating the heat discharge and effectively reducing the temperature inside the cabinet. However, multi-channel heat dissipation may cause the air flow to concentrate in some channels while the air flow in other channels is weak, resulting in the contact of the channels with weak air flow with the external environment, causing dust to enter the heat dissipation channels and accumulate on the inner wall of the channels to form a heat insulation layer, increasing the resistance of heat transfer, affecting the heat dissipation effect of the cabinet, and thus causing uneven temperature distribution inside the cabinet.

This disturbance destroys the laminar state of the hot air flow, making the hot air flow more easily mix with the surrounding air and form a turbulent flow conducive to discharge.

The turbulent flow of the air flow will exert a dynamic force, destroying the adhesion condition between the dust and the surface of the heat dissipation channel, making the dust break away from the adhesion point, so that the complex path of the disturbed air flow can cover all areas of the heat dissipation channel, preventing the dust from accumulating excessively in a certain local position, and improving the heat dissipation efficiency in the exhaust assembly; 4. Through the arrangement of the air guiding assembly, the heat dissipation channel and the drainage blades, the present invention can realize the formation of a secondary circulation of the air flow in the heat dissipation channel. The re-introduced air flow will destroy the static air layer near the wall surface of the air flow 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 through more quickly and smoothly, taking away the heat generated inside the cabinet in time; 5. Through the settings of the air guiding pipe, the air guiding blades and the heat dissipation channels, the air flow re-introduced into the heat dissipation channels by the air guiding pipe can cooperate synergistically with the air guiding blades. The re-introduced air flow will scour the dust on the heat dissipation channels and the air guiding blades, reducing the accumulation of dust on the surfaces of the air guiding blades and the heat dissipation channels, preventing dust from being adsorbed inside the heat dissipation channels, enabling heat to be transferred more smoothly from the heat dissipation channels to the flowing air, and improving the heat dissipation efficiency. 6. Through the settings of the knocking assembly, the stabilizing sleeve, the air guiding blades and the heat dissipation channels, knocking at different positions inside the stabilizing sleeve is achieved, thereby generating vibrations on the stabilizing sleeve and the air guiding blades, which are used to disrupt the electrostatic field on the surfaces of the air guiding blades, reduce the adhesion of dust to the air guiding blades, decrease the adsorption of dust, increase the contact area between the air flow and the air guiding blades, facilitate the rapid discharge of the air flow inside the heat dissipation channels, enable the radiator to achieve the same heat dissipation effect at a lower power, thereby reducing the energy consumption of the entire cabinet and reducing the operating cost.

Detailed implementation manners

[0016] 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 introduced in detail below in conjunction with the drawings.

[0017] The present invention provides a distribution cabinet with a multi-channel heat dissipation function as shown in Figure 1 , Figure 2 and Figure 3 , including a cabinet 1 and a heat dissipation box 11. A plurality of heat dissipation channels 13 are provided between the cabinet 1 and the heat dissipation box 11, and radiators 12 are installed in the heat dissipation channels 13. The radiators 12 are used to discharge the internal heat flow of the cabinet 1 outward along the heat dissipation channels 13. An exhaust assembly 2 for changing the air flow path is commonly connected between the radiators 12 and the heat dissipation channels 13. And under the guidance of the exhaust assembly 2, the adsorption of impurities on the inner wall of the heat dissipation channel 13 is reduced. A repeated movement assembly 3 is commonly connected between the exhaust assembly 2 and the heat dissipation channels 13. And the repeated movement assembly 3 is used to drive the exhaust assembly 2 to rotate and move up and down in the heat dissipation channel 13 at the same time, so that the air flow can be scattered inside the heat dissipation channel 13. Two symmetrical air guiding assemblies 6 are commonly connected between the radiators 12 and the heat dissipation channels 13. And the air guiding assemblies 6 are used to guide the heat flow generated in the radiators 12 and convey the guided heat flow into the exhaust assembly 2 to ensure the stable guidance of the air flow by the exhaust assembly 2, which is beneficial to maintaining good heat dissipation in the cabinet 1; In addition, the specific structure and principle of the radiator 12 are both prior arts, so no further elaboration is made 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: 1. Blades: Responsible for pushing air flow, usually using axial flow or centrifugal design; 2. Motor: Drives the blades to rotate, guides the air flow direction, and ensures that air is discharged from the specified path. It can be an AC motor, a DC motor, or a brushless motor; 3. Frame: Supports the blades and the motor, usually made of plastic or metal, and is often installed on the top, side, or bottom of the cabinet for discharging the heated hot air.

[0018] Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5 As shown in, the exhaust assembly 2 includes a rotating column 25 rotatably connected inside the radiator 12 and a stabilizing sleeve 21 rotatably connected inside the heat dissipation channel 13. A plurality of drainage vanes 22 are fixedly connected to the outside of the stabilizing sleeve 21, and the drainage vanes 22 are provided with a meandering willow leaf-shaped structure. A plurality of through holes 23 for guiding the air flow are opened on the outside of the drainage vanes 22. A guiding column 24 is fixedly connected to the bottom end of the rotating column 25, and the stabilizing sleeve 21 is movably sleeved on the outside of the guiding column 24; In addition, when the air flow contacts the drainage vanes 22, the air flow moves along the surface of the drainage vanes 22, and a part of the air flow on the surface of the drainage vanes 22 passes through the through holes 23, so that the air flow is stratified near the drainage vanes 22, increasing the residence time of the air flow in the heat dissipation channel 13. During this process, the rotation of the drainage vanes 22 will have a certain cleaning effect on the heat dissipation channel 13. Therefore, the drainage vanes 22 can allow the air flow to have more time to blow the dust in the heat dissipation channel 13, reducing the accumulation of dust in the heat dissipation channel 13 and avoiding the occurrence of the situation where the heat dissipation efficiency decreases due to dust coverage; Reference Figure 1 、 Figure 2 、 Figure 3 and Figure 5As 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 the absorbed hot air is transported to the inside of the heat dissipation channel 13, and during the rotation of the radiator 12, its output end 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, and 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 inside of the heat dissipation channel 13. The hot air in the heat dissipation channel 13 is guided, and the guide blades 22 themselves can extend the path of the hot air, so that the hot air can maintain sufficient 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.

[0019] refer to Figure 3 , Figure 6 and Figure 7 As shown, the relocation 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 a guide block 36, and the guide block 36 is slidably connected to the flow limiting groove 34; the relocation assembly 3 also includes a fixing ring 31 fixedly connected to the bottom of a plurality of guide blades 22 and a push ring 32 installed in the heat dissipation channel 13, and the top end of the push ring 32 is set to an inclined ring shape, and the bottom end of the fixing ring 31 is installed There is a push column 33, and the bottom end of the push column 33 is attached to the top end of the push ring 32, and the push ring 32 is used to push the push column 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 column 24 and the stabilizing sleeve 21, and the knocking component 5 is used to clean the dust on the stabilizing sleeve 21 and the guide vane 22. A loosening component 4 is provided between the push ring 32 and the radiator 12, and the loosening component 4 is used to adjust the height of the guide vane 22 in the heat dissipation channel 13 upward or downward; In addition, the movement state of the guide blades 22 keeps disturbing the hot air in the heat dissipation channel 13. The turbulence of the airflow will exert dynamic force, destroying the attachment conditions of dust to the surface of the heat dissipation channel 13, so that the dust is separated from the attachment point, so that the complex path of the disturbed airflow can cover various areas of the heat dissipation channel 13, preventing excessive accumulation of dust in a certain local position. In addition, the hot air discharged from the heat dissipation channel 13 can reduce the viscosity of some dust particles, making them easier to remove, thereby improving the heat dissipation efficiency in the cabinet 1; refer to Figure 3, Figure 6 and Figure 7 As shown, when the guide post 24 rotates and drives the stable sleeve 21 to rotate inside the heat dissipation channel 13, the rotation of the guide post 24 drives the current-limiting groove 34 to rotate synchronously. Immediately, the rotation of the current-limiting groove 34 drives the drainage block 36 and the stable ring 35 to rotate synchronously inside the stable sleeve 21, causing the stable sleeve 21 to rotate following the rotation of the guide post 24. At this time, the stable sleeve 21 is in a rotating state inside the heat dissipation channel 13. During this process, when it is necessary to drive the stable sleeve 21 to move upward along the outside of the guide post 24 while the stable sleeve 21 is rotating, the rotation of the stable sleeve 21 drives the drainage blades 22 to rotate synchronously. Through the rotation of the drainage blades 22, the fixed ring 31 is driven to rotate synchronously inside the heat dissipation channel 13. Immediately, the rotation of the fixed ring 31 drives the push post 33 to move guidingly along the top of the push ring 32. At this time, the push post 33 continuously moves upward along the top of the push ring 32, causing the distance between the fixed ring 31 and the push ring 32 to change continuously. At this time, the fixed ring 31 moves upward inside the heat dissipation channel 13 under the movement of the push post 33, and the fixed ring 31 moves downward to push the stable sleeve 21 upward. Moreover, the upward-moving stable sleeve 21 moves upward synchronously along the outside of the guide post 24. Thus, the upward movement of the stable sleeve 21 drives the drainage block 36 to move upward synchronously inside the current-limiting groove 34. Subsequently, the stable sleeve 21 not only realizes a rotating motion state inside the heat dissipation channel 13 but also realizes upward movement inside the heat dissipation channel 13 while rotating, enabling the movement state of the drainage blades 22 to be adjusted flexibly inside the heat dissipation channel 13; the drainage blades 22 realize a combined motion of rotation and vertical movement inside the heat dissipation channel 13, causing the drainage blades 22 to generate a stronger disturbance to the surrounding hot air flow. This disturbance destroys the laminar state of the hot air flow, making the hot air flow more likely to mix with the surrounding air and form a turbulent flow conducive to discharge. In the turbulent flow state, the diffusion speed of the hot air flow increases, and it can be more quickly guided to the air outlet of the heat dissipation channel 13, thereby enhancing the hot air flow discharge capacity of the entire heat dissipation channel 13.

[0020] 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 inside 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 outside of the air induced pipe 61 is movably sleeved with a spiral sleeve 64, the inside of the sealing sleeve 62 is fixedly connected with a support ring 66, and the support ring 66 is sleeved on the outside 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 the spiral sleeve 64 to be screwed, and the interior of the spiral sleeve 64 is provided with a displacement groove 69 that matches the elastic pad 68, and the displacement groove 69 is used to gather the elastic pad 68 to the outside of the induced air duct 61 and lock the induced air duct 61 in the sealing sleeve 62, and the plug sleeve 63 is inserted and pulled out 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 a good match; 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 threaded engagement 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 resistance, 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 the locking with the outside of the air duct 61. As the air duct 61 is pushed, it is guided and moved along the elastic pad 68, the sealing sleeve 62 and the eccentric soft plate 67. Then, 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 a suitable length. After the position adjustment of the air duct 61 is completed, the above steps can be reversed to achieve the re-locking of the air duct 61 in the sealing sleeve 62 and the heat dissipation channel 13. refer to Figure 11 and Figure 12As shown, the two air intake pipes 61 are respectively located on both sides of the radiator 12 and the heat dissipation channel 13. The two air intake pipes 61 can provide an additional exhaust path for the radiator 12 and the heat dissipation channel 13, disperse the airflow for discharge, and guide the hot air to be discharged briefly from different positions, which can promote the internal and external interaction between the hot air and the air outside the air intake pipes 61. Moreover, the two air intake pipes 61 reintroduce part of the discharged airflow into the heat dissipation channel 13 to form a secondary cycle. The reintroduced airflow will disrupt the stationary air layer near the wall surface of the airflow in the heat dissipation channel 13, promote the transfer of heat from the wall surface to the mainstream airflow, enable the airflow to pass through more quickly and smoothly, and timely take away the heat generated in the cabinet 1. In addition, the airflow reintroduced into the heat dissipation channel 13 by the air intake pipes 61 can cooperate synergistically with the drainage blades 22. The reintroduced airflow will scour the dust in the heat dissipation channel 13 and the drainage blades 22, reduce the accumulation of dust on the surfaces of the drainage blades 22 and the heat dissipation channel 13, prevent dust from being adsorbed in the heat dissipation channel 13, enable heat to be transferred more smoothly from the heat dissipation channel 13 to the flowing air, improve the heat dissipation efficiency, and ensure the operation of the electrical equipment in the cabinet 1 in a suitable temperature environment.

[0021] Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 7 As shown in ,

[0021] , Figure 3 , Figure 4 , Figure 5 , and Figure 7 , the tightening assembly 4 includes an engagement ring 41 fixedly connected to the bottom end of the radiator 12, an external thread ring 45 sleeved on the bottom of the push ring 32, and a thread groove 46 opened in the heat dissipation channel 13 for screwing the external thread ring 45. The top end of the stable sleeve 21 is fixedly sleeved with a centering ring 44. The bottom end of the engagement ring 41 is fixedly connected with a support spring 42. One end of the support spring 42 close to the centering ring 44 is fixedly connected with a bottom ring frame 43, and the bottom ring frame 43 is movably connected with the centering ring 44; Reference Figure 3 、 Figure 4 、 Figure 5 and Figure 7As shown, when it is necessary to adjust the elastic tension between the drainage blade 22 and the radiator 12 in the heat dissipation channel 13, the push ring 32 is rotated to drive its outer part and the external thread ring 45 to rotate synchronously along the heat dissipation channel 13. Immediately, during the rotation of the external thread ring 45, it remains in screw engagement with the thread groove 46, causing the push ring 32 to move 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. Moreover, during the movement of the centering ring 44, it pushes the drainage blade 22 to move downward. Thus, the movement of the drainage blade 22 pushes the fixed ring 31 to move synchronously, ensuring stable contact between the push post 33 and the push ring 32. Subsequently, the elastic expansion and contraction of the support spring 42 is adjusted, enabling the tightness between the drainage blade 22 and the radiator 12 to be adjusted synchronously, ensuring the flexible rotation of the drainage blade 22. At the same time, the adjustment of the tightness between the drainage blade 22 and the radiator 12 ensures the stable reciprocating movement of the drainage blade 22 upward or downward along the heat dissipation channel 13, enabling the drainage blade 22 to maintain a reciprocating alternating movement with the air duct 61. This is conducive to the up-and-down alternating movement between the position of the drainage blade 22 and the air duct 61, capable of blowing different positions on the outside of the drainage blade 22, reducing the adsorption of dust on the surface of the drainage blade 22, enabling the drainage blade 22 to clean the dust on the inner wall of the heat dissipation channel 13 in a timely manner, and avoiding the formation of a heat insulation layer due to dust accumulation in the heat dissipation channel 13, reducing the heat transfer resistance and enhancing the heat dissipation efficiency of the cabinet 1.

A chute 56 for the movement of the two knocking blocks 53 is opened at the bottom end of the fixed disk 52. A contraction box 54 is fixedly connected to the middle part inside the chute 56. A sliding column 55 is fixedly connected to one side of each of the two knocking blocks 53 corresponding to each other, and one end of each of the two sliding columns 55 extends into the inside of the contraction box 54 and is connected with an ejecting spring 57; the two bump plates 51 are arranged in a wavy structure, and the wavy structures of the two bump plates 51 are arranged in an alternating manner. One side of the two knocking blocks 53 close to the two bump plates 51 is arranged in a conical structure; 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 during the upward movement process. 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. 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 contacts with the knocking blocks 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 and pushes one of the slide columns 55 to move along the inside of the contraction box 54, and one of the slide columns 55 pushes the ejection spring 57 to move. During this process, another knocking block 53 contacts with another bumping plate 51, so that the ejection spring 57 is squeezed between the two slide columns 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 recessed part of one of the bumping plates 51, and then the ejection spring 57 elastically stretches to give one end of one of the slide columns 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, and similarly, another knocking block 53 and the recess of another bumping plate 51 produce a knocking, and reciprocate in sequence, and alternate knocking is achieved between the two bumping plates 51 and the two fixed plates 52, thereby achieving knocking at different positions in the stabilizing sleeve 21, thereby generating vibrations for 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 the airflow in the heat dissipation channel 13, so that the radiator 12 can achieve the same heat dissipation effect at a lower power, thereby reducing the overall energy consumption and reducing the operating cost.

[0023] Working principle: When in use; refer to Figure 1 , Figure 2 and Figure 3As 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 the output end of the radiator 12 drives the rotating column 25 to rotate synchronously during the rotation process, 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 a number of 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, and 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, and preventing the occurrence of local airflow obstruction.

[0024] 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 complex shifting assembly 3 cooperate with each other, and the guide blades 22 realize the 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, and this disturbance destroys the laminar state of the hot air flow, making it easier for the hot air flow to mix with the surrounding air and form turbulence that is conducive to discharge. Under 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.

[0025] 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 vane 22, the spiral sleeve 64 is rotated to keep it in screwing 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 resistance, 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 is elastically reset, so that one side of the elastic pad 68 loses the locking situation 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 then 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 vane 22.

[0026] refer to Figure 6 , Figure 8 ,Figure 9 , Figure 10 and Figure 11 As shown in Figure 9 , Figure 10 and Figure 11 , during the upward movement of the stabilizing sleeve 21 and the drainage vane 22 along the heat dissipation channel 13, the knocking assembly 5 can achieve knocking at different positions inside the stabilizing sleeve 21, thereby generating vibrations on the stabilizing sleeve 21 and the drainage vane 22, which is used to disrupt the electrostatic field on the surface of the drainage vane 22, reduce the dust adhesion on the drainage vane 22, decrease the dust adsorption, increase the contact area between the air flow and the drainage vane 22, facilitate the rapid discharge of the air flow in the heat dissipation channel 13, enable the radiator 12 to achieve the same heat dissipation effect at a lower power, thus reducing the energy consumption of the entire cabinet 1 and decreasing the operating cost.
