Description

Technical Field

[0001] This application relates to the field of cable trays, and more particularly to an energy-saving cable tray. Background Technology

[0002] Cable trays are mainly used as supporting components for laying cables in integrated cabling systems such as power transmission and wired telecommunications.

[0003] Existing cable trays include two parallel connecting arms with a connecting rod fixed between them. The connecting rod supports the cables, and the connecting arms are fixedly connected to the building ceiling or building components via hangers.

[0004] When transmitting high current, the cable will generate a certain amount of heat, which will exchange with the outside air. When the heat exchange effect is poor, the cable's heat dissipation effect will be poor, thereby increasing the current transmission loss. Summary of the Invention

[0005] In order to improve the heat dissipation of cables and thus reduce current transmission losses, this application provides an energy-saving cable tray.

[0006] This application provides an energy-saving cable tray, which adopts the following technical solution: An energy-saving cable tray includes a connecting arm, a first horizontal tube, a movable air circulation mechanism, and a traction mechanism. The connecting arm is a square tube structure, and two parallel connecting arms are provided. The first horizontal tubes are spaced apart along the length of the connecting arm and are used to support cables. The upper part of the first horizontal tube has a first through hole corresponding to the cable. The connecting arm has a second through hole for communication with the end of the first horizontal tube. The connecting arm also has an elongated third through hole, which is offset from the second through hole along the length of the connecting arm. The movable air circulation mechanism includes a housing, a fan assembly, and an exhaust square tube. The housing slides against the inner wall of the connecting arm. The connection includes a traction mechanism for moving the housing relative to the connecting arm. The housing has a transfer chamber and an air outlet chamber. The transfer chamber has a first air inlet and a second air inlet. The opening of the first air inlet has a first ventilation pipe head made of rubber, and the opening of the first ventilation pipe head is used to communicate with a third through hole. The opening of the second air inlet has a long strip-shaped second ventilation pipe head made of rubber, and the opening of the second ventilation pipe head is used to communicate with a second through hole. The air inlet end of the fan assembly is connected to the transfer chamber, and the air outlet end of the fan assembly is connected to the air outlet chamber. One end of the exhaust square pipe is inclined downward toward the first horizontal pipe, and the other end of the exhaust square pipe is connected to the air outlet chamber.

[0007] By adopting the above technical solution, when the cable transmits a large current, the traction mechanism drives the housing to move and the fan assembly is started. During the movement, the first ventilation pipe head and the third through hole on the housing are connected, and the second ventilation pipe head and the second through hole are connected. The above two connections are alternately realized during the movement of the housing.

[0008] When the first ventilation duct head and the third through hole are connected, fresh air from the outside of the connecting arm is drawn into the transfer chamber by the fan assembly through the third through hole and the first ventilation duct head in sequence. Then, it is delivered to the cable between the two connecting arms through the air outlet chamber and the exhaust square pipe in sequence, thereby forming a fresh air flow to replace the hot air near the cable. When the second ventilation duct head and the second through hole are connected, the hot air near the cable will enter the first horizontal pipe from the first through hole and enter the transfer chamber to mix with the external fresh air for cooling. In addition, the negative pressure state of the first through hole can also pull the fresh air discharged by the exhaust square pipe, thereby increasing the fresh air circulation speed and improving the heat dissipation effect.

[0009] In this way, by connecting the first ventilation duct head and the third through hole, and connecting the second ventilation duct head and the second through hole, the two connection methods can be carried out alternately, which can realize the delivery of fresh air, the acceleration of fresh air circulation, and the exhaust of hot air, thereby greatly improving the heat dissipation effect of the cable and reducing the current transmission loss of the cable, so as to achieve energy saving.

[0010] Furthermore, by setting an elongated third through hole and an elongated second ventilation pipe head, it is possible to ensure that the air duct remains continuously connected during the continuous movement of the casing, thereby achieving continuous delivery of fresh air, continuous acceleration of fresh air circulation, and continuous exhaust of hot air.

[0011] Optionally, the traction mechanism is provided as two, and each of the two connecting arms is configured to correspond one-to-one with the mobile air circulation mechanism; the control methods of the two traction mechanisms include the following: the two traction mechanisms drive the two housings to move synchronously at the same end of the two connecting arms and in the same direction; or, the two traction mechanisms drive the two housings to move synchronously towards the middle at the opposite ends of the two connecting arms.

[0012] By adopting the above technical solution and setting up independent traction mechanisms, the displacement of the two moving air circulation mechanisms can be controlled separately. The first control method is suitable for short-distance cable trays for high-efficiency heat dissipation. The second control method, in which the two moving air circulation mechanisms move towards each other, has higher heat dissipation efficiency and is suitable for long-distance cable trays.

[0013] Optionally, there are two traction mechanisms, each corresponding to one of the moving air circulation mechanisms of the two connecting arms. The control methods of the two traction mechanisms include the following: the two housings are staggered along the length of the connecting arm, the distance between the two housings is equal to half the distance between two adjacent first horizontal pipes, and the two traction mechanisms drive the two housings to move synchronously in the same direction.

[0014] By adopting the above technical solution, firstly, the fresh air discharged by the two staggered moving air circulation mechanisms is staggered, and the two staggered fresh air will form a vortex near the cable, thereby increasing the duration of fresh air near the cable and thus improving the heat dissipation effect.

[0015] Secondly, by setting a staggered distance between the two mobile air circulation mechanisms, when one mobile air circulation mechanism draws in hot air, the other mobile air circulation mechanism delivers fresh air, thereby achieving the synchronous delivery of fresh air and the extraction of hot air, which further improves the fresh air refresh rate and enhances the heat dissipation effect.

[0016] The above control method is mainly suitable for medium-to-long-distance cable trays and for high-current transmission over a relatively long period of time.

[0017] Optionally, the traction mechanism is provided as two, and each of the two connecting arms is configured to correspond one-to-one with the mobile air circulation mechanism; the control method of the two traction mechanisms further includes the following: the two housings are staggered along the length direction of the connecting arm, and the two traction mechanisms respectively drive the two housings to move intermittently and alternately in the same direction.

[0018] By adopting the above technical solution, when the two mobile air circulation mechanisms move alternately, both swirling and turbulent flow are formed. Swirling flow can improve the continuity of heat dissipation, while turbulent flow has a high fresh air velocity, which can improve the heat dissipation effect. Thus, it has both the continuity and the effect of heat dissipation, making it suitable for medium-distance cable trays and long-term high-current transmission.

[0019] Optionally, the exhaust square tube is connected to the housing via a rubber bellows tube, and a guide ridge extending along the length of the connecting arm is fixed to the outer wall of the connecting arm. The guide ridge has a wavy protrusion that abuts against the lower surface of the exhaust square tube.

[0020] By adopting the above technical solution, through the flexible connection of the exhaust square tube, under the action of gravity, the exhaust square tube hangs down to the state of abutting the wave protrusion. When the moving air circulation mechanism moves along the length of the connecting arm, the exhaust square tube moves up and down through the abutting of the wave protrusion with the exhaust square tube, and the diffusion range of the fresh air discharged from the exhaust square tube is greatly improved, thereby improving the heat dissipation range.

[0021] Optionally, the exhaust square tube is provided with multiple swing blades, and a rotating shaft is fixed on the side of the swing blades near the housing. The rotating shaft is perpendicular to the inner wall of the exhaust square tube and is rotatably connected to the inner wall of the exhaust square tube. A counterweight is fixed on the side of the swing blades away from the rotating shaft.

[0022] By adopting the above technical solution, firstly, when the casing moves intermittently, the inertia at the moment of startup and the moment of stopping will force the swing blades to swing, thereby guiding the fresh air and improving the heat dissipation range.

[0023] Secondly, when the exhaust square duct moves up and down under the contact of the corrugated protrusions, the axial direction of the rotating shaft changes, the center of gravity of the counterweight changes, and the oscillating blades oscillate, thereby guiding the fresh air and improving the heat dissipation range.

[0024] Optionally, a plurality of second horizontal tubes and a plurality of third horizontal tubes are provided between the two connecting arms. The second horizontal tubes are located above the first horizontal tube, and two second horizontal tubes are arranged corresponding to one first horizontal tube. The two second horizontal tubes are symmetrically arranged with the first horizontal tube as the center. The ends of the second horizontal tubes are fixedly connected to the ends of the first horizontal tubes by a first support rod. The second horizontal tubes are used to support a set of cables. The third horizontal tubes are located directly above the second horizontal tubes, and the ends of the third horizontal tubes are fixedly connected to the ends of the second horizontal tubes by a second support rod. The third horizontal tubes are used to support a set of cables.

[0025] By adopting the above technical solution, and by setting up a second horizontal tube and a third horizontal tube, multiple groups of cables can be layered, thereby reducing the heat concentration caused by the accumulation of multiple cables.

[0026] Optionally, the first horizontal tube is rotatably connected to the connecting arm around its own axis, and a toothed ring is fixed at the end of the first horizontal tube. The toothed ring has a toothed segment with a circumference of one-twelfth. Both ends of the second ventilation pipe head are provided with clearance slits, and the inner wall of the second ventilation pipe head is integrally formed with a rubber toothed strip, which meshes with the toothed segment of the toothed ring.

[0027] By adopting the above technical solution, when the mobile air circulation mechanism moves, the rack on the second ventilation duct head meshes with the exposed toothed ring of the first horizontal pipe, thereby driving the first horizontal pipe to rotate 30°. The first horizontal pipe drives the second and third horizontal pipes to rotate together, thereby partially lifting the upper two sets of cables to increase the vertical distance between the exhaust square pipe and the exhaust cable, thereby increasing the fresh air passage diameter, improving the heat dissipation effect, and reducing the occurrence of heat accumulation.

[0028] Furthermore, by setting an avoidance slit, when the second ventilation pipe head collides with the protruding toothed ring, the deformation of the second ventilation pipe head itself will cause the avoidance slit to open, allowing the toothed ring to enter the second ventilation pipe head and mesh with the rack, thereby reducing interference collisions.

[0029] Optionally, the housing is provided with a water tank, a water inlet, and a sealing plug for opening and closing the water inlet. The water tank is located on one side of the air outlet of the fan assembly, and a ceramic atomizing plate is provided in the water tank.

[0030] By adopting the above technical solution, low-temperature water can be added to the water tank through the water inlet, and then the low-temperature water can be atomized by the high-frequency vibration of the ceramic atomizing plate. Then, the low-temperature fresh air is delivered to the vicinity of the cable through the fan assembly, so as to greatly reduce the temperature of the cable and improve the heat dissipation effect.

[0031] Optionally, the traction mechanism includes two take-up and release rollers and a drive motor for driving the take-up and release rollers to rotate. The two take-up and release rollers are located at both ends of the connecting arm, and a traction rope is fixedly connected between the take-up and release rollers and the housing.

[0032] By adopting the above technical solution, and by setting up take-up and release rollers and traction ropes, the housing can be moved along the length of the connecting arm, and it is suitable for the bends of cable trays.

[0033] In summary, this application includes at least one of the following beneficial technical effects: 1. The first ventilation duct head and the third through hole are connected, and the second ventilation duct head is connected to the second through hole. The two connection methods are carried out alternately. With the help of the fan assembly, the supply of fresh air, the circulation of fresh air is accelerated, and the exhaust of hot air can be realized. This greatly improves the heat dissipation effect of the cable and reduces the current transmission loss of the cable, so as to achieve energy saving. 2. By setting up an independent traction mechanism, the displacement of the two mobile air circulation mechanisms can be controlled separately to control the heat dissipation effect, heat dissipation efficiency and heat dissipation duration, thereby matching them for different operating conditions and making them more adaptable; 3. By setting up the cooperation between the first horizontal pipe and the second ventilation pipe head, when the moving air circulation mechanism moves, the rack on the second ventilation pipe head meshes with the exposed toothed ring of the first horizontal pipe, so as to drive the first horizontal pipe to rotate 30°. The first horizontal pipe drives the second and third horizontal pipes to rotate together, thereby partially lifting the upper two sets of cables, increasing the vertical distance between the exhaust square pipe and the exhaust cable, thereby increasing the fresh air passage diameter, improving the heat dissipation effect, and reducing the occurrence of heat accumulation.

[0047] The following is in conjunction with the appendix Figure 1-12 This application will be described in further detail.

[0048] Embodiment 1 of this application discloses an energy-saving cable tray.

[0049] Reference Figure 1The energy-saving cable tray includes a connecting arm 1, a first horizontal tube 3, a moving air circulation mechanism 20, and a traction mechanism 2. The connecting arm 1 is a square tube structure. There are two connecting arms 1 that are parallel to each other. Each first horizontal tube 3 is arranged at intervals along the length of the connecting arm 1. The two ends of the first horizontal tube 3 are fixedly connected to the two connecting arms 1 respectively. The first horizontal tube 3 is used to support the cable 10.

[0050] like Figure 2 As shown, the upper part of the first horizontal tube 3 is provided with a first through hole 31 corresponding to the cable 10. The recessed part formed by the first through hole 31 can position the cable 10, and the size of the first through hole 31 is larger than the diameter of the cable 10. The connecting arm 1 is provided with a second through hole 12, which is connected to the end of the first horizontal tube 3, that is, the first horizontal tube 3 is connected to the inner cavity of the connecting arm 1.

[0051] A notch 11 is provided through the long side of the upper surface of the connecting arm 1, and a third through hole 13 is provided through the side wall of the connecting arm 1 opposite to the second through hole 12. The third through hole 13 is elongated, and the length direction of the third through hole 13 is the length direction of the connecting arm 1. The third through hole 13 and the second through hole 12 are offset from each other along the length direction of the connecting arm 1.

[0052] like Figure 1 As shown, the mobile air circulation mechanism 20 is disposed in the inner cavity of the connecting arm 1. The mobile air circulation mechanism 20 can slide along the length direction of the connecting arm 1. There are two traction mechanisms 2, and the two traction mechanisms 2 are arranged one-to-one with the mobile air circulation mechanisms 20 of the two connecting arms 1. The traction mechanisms 2 are used to control the movement of the mobile air circulation mechanism 20.

[0053] like Figure 3 , Figure 4 As shown, the mobile air circulation mechanism 20 includes a housing 5, a fan assembly 6, and an exhaust square pipe 53. The housing 5 is a cube and is slidably connected to the inner wall of the connecting arm 1. The fan assembly 6 is installed inside the housing 5. The fan assembly 6 can be powered by a battery or by an external power cord. The fan assembly 6 is arranged along the diagonal of the housing 5 and divides the housing 5 into a transfer chamber 51 and an exhaust chamber 52. The exhaust chamber 52 is located above the transfer chamber 51. The air inlet of the fan assembly 6 is connected to the transfer chamber 51, and the air outlet of the fan assembly 6 is connected to the exhaust chamber 52.

[0054] The transfer chamber 51 has a first air inlet and a second air inlet on its opposite side walls. The opening of the first air inlet is provided with a first ventilation pipe head 55 made of rubber. The first ventilation pipe head 55 is circular. The opening of the second air inlet is provided with a long strip of second ventilation pipe head 56 made of rubber. The opening of the first ventilation pipe head 55 abuts against one inner wall of the connecting arm 1, and the opening of the second ventilation pipe head 56 abuts against the other inner wall of the connecting arm 1.

[0055] One end of the exhaust square tube 53 is connected to the air outlet chamber 52 through the rubber bellows tube 54, and the other end of the exhaust square tube 53 extends out of the connecting arm 1 through the notch 11 of the connecting arm 1. This end of the exhaust square tube 53 is inclined downward toward the first horizontal tube 3, that is, toward the cable 10.

[0056] like Figure 1 As shown, the traction mechanism 2 includes two take-up and untake-up rollers 21 and a drive motor 22 for driving the take-up and untake-up rollers 21 to rotate. The two take-up and untake-up rollers 21 and the two drive motors 22 are respectively arranged at both ends of the connecting arm 1 along its length. A traction rope 23 is fixedly connected between the take-up and untake-up rollers 21 and the housing 5. That is, by using one take-up and untake-up roller 21 to take up and the other take-up and untake-up roller 21 to unwind, the housing 5 is driven to slide relative to the connecting arm 1.

[0057] like Figure 5 As shown, when the traction mechanism 2 moves the housing 5, the fan assembly 6 is activated. During the movement, the first ventilation pipe head 55 on the housing 5 can move to the position of the third through hole 13, so that the first ventilation pipe head 55 is connected to the third through hole 13. Meanwhile, the second ventilation pipe head 56 on the housing 5 can move to the position of the second through hole 12, so that the second ventilation pipe head 56 is connected to the second through hole 12. Since the second through hole 12 and the third through hole 13 are misaligned, the above two connections are alternately realized during the movement of the housing 5. When the first ventilation pipe head 55 is connected to the third through hole 13, the second ventilation pipe head 56 is not connected to the second through hole 12.

[0058] When the first ventilation duct head 55 and the third through hole 13 are connected, the fresh air outside the connecting arm 1 is drawn into the transfer chamber 51 by the fan assembly 6 through the third through hole 13 and the first ventilation duct head 55 in sequence, and then delivered to the cable 10 between the two connecting arms 1 in sequence through the air outlet chamber 52 and the exhaust square pipe 53, thereby forming a fresh air flow to replace the hot air near the cable 10.

[0059] When the second ventilation duct head 56 and the second through hole 12 are connected, the hot air near the cable 10 will enter the first horizontal pipe 3 from the first through hole 31 and enter the transfer chamber 51 to mix with the external fresh air to cool down. In addition, the negative pressure state of the first through hole 31 can also pull the fresh air discharged by the exhaust square pipe 53, thereby increasing the fresh air circulation speed and improving the heat dissipation effect.

[0060] In this way, by alternating between the two connection methods, it is possible to deliver fresh air, accelerate the circulation of fresh air, and exhaust hot air, thereby greatly improving the heat dissipation effect of cable 10 and reducing the current transmission loss of cable 10, thus achieving energy saving.

[0061] Furthermore, since the traction mechanism 2 independently controls a mobile air circulation mechanism 20, the movement control mode of the mobile air circulation mechanism 20 can be adjusted according to the actual situation of the cable 10. The movement control modes include the following four types.

[0062] The first type involves two traction mechanisms 2 driving two housings 5 ​​to move synchronously and in the same direction at the same end of two connecting arms 1. This is suitable for short-distance cable trays for high-performance heat dissipation.

[0063] The second type involves two traction mechanisms 2 driving two housings 5 ​​to move synchronously towards the center from opposite ends of two connecting arms 1, i.e., two moving air circulation mechanisms 20 moving towards each other, resulting in higher heat dissipation efficiency and suitability for long-distance cable trays.

[0064] Under normal circumstances, the two methods mentioned above are generally preferred.

[0065] The third type, such as Figure 6 As shown, the initial position is that the two housings 5 ​​are staggered along the length of the connecting arm 1, and the distance between the two housings 5 ​​is equal to half the distance between the two adjacent first horizontal tubes 3. Then, the two traction mechanisms 2 drive the two housings 5 ​​to move synchronously in the same direction.

[0066] In this way, the fresh air discharged by the two staggered moving air circulation mechanisms 20 is staggered, and the two staggered fresh air will form a vortex near the cable 10, thereby increasing the duration of fresh air near the cable 10 and thus improving the heat dissipation effect.

[0067] Furthermore, while one of the mobile air circulation mechanisms 20 is drawing in hot air, the other mobile air circulation mechanism 20 is delivering fresh air, thereby achieving the simultaneous delivery of fresh air and the extraction of hot air, which further improves the fresh air refresh rate and enhances the heat dissipation effect.

[0068] The above control method is mainly suitable for medium-to-long-distance cable trays and for high-current transmission over a relatively long period of time.

[0069] The fourth type, such as Figure 7 As shown, the initial position is that the two housings 5 ​​are staggered along the length of the connecting arm 1. The movement method is that the two traction mechanisms 2 drive the two housings 5 ​​to move intermittently and alternately in the same direction. That is, one of the moving air circulation mechanisms 20 moves a certain distance and stops, and the other moving air circulation mechanism 20 moves a certain distance and stops, and the two alternate.

[0070] When the two moving air circulation mechanisms 20 move alternately, they create both swirling and turbulent flow. Swirling flow can improve the continuity of heat dissipation, while turbulent flow has a high fresh air velocity, which can improve the heat dissipation effect. Thus, it has both continuous heat dissipation and heat dissipation effect, making it suitable for medium-distance cable trays and long-term high current transmission.

[0071] Example 2 The difference between Example 2 and Example 1 is that, as Figure 8 As shown, a guide ridge 14 is fixed on the side wall of the connecting arm 1 facing the other connecting arm 1. The guide ridge 14 extends along the length of the connecting arm 1. The guide ridge 14 is provided with a wave protrusion 15, which abuts against the lower surface of the exhaust square pipe 53.

[0072] Since the exhaust square pipe 53 is a flexible connection, under the action of gravity, the exhaust square pipe 53 droops down to the state of abutting the wave protrusion 15. At this time, the exhaust square pipe 53 is in a downward tilted state.

[0073] When the mobile air circulation mechanism 20 moves along the length of the connecting arm 1, the exhaust square pipe 53 swings up and down through the contact between the wave protrusion 15 and the exhaust square pipe 53, which greatly increases the diffusion range of the fresh air discharged from the exhaust square pipe 53, thereby improving the heat dissipation range.

[0074] Example 3 The difference between Example 3 and Example 2 is that, as Figure 9 As shown, the exhaust square tube 53 is provided with multiple swing blades 531. Specifically, a rotating shaft 532 is fixed on the side of the swing blade 531 near the housing 5. The rotating shaft 532 is perpendicular to the inner wall of the exhaust square tube 53, and the rotating shaft 532 is rotatably connected to the inner wall of the exhaust square tube 53 around its own axis.

[0075] A counterweight 533 is fixed on the side of the oscillating blade 531 away from the rotation axis 532, and the counterweight 533 is parallel to the rotation axis 532.

[0076] When the exhaust square pipe 53 moves up and down under the contact of the corrugated protrusion 15, the axial direction of the rotating shaft 532 changes, the center of gravity of the counterweight bar 533 changes, thereby causing the swing blade 531 to swing on its own, thus guiding the fresh air to improve the heat dissipation range.

[0077] Example 4 The difference between Example 4 and Example 1 is that, as Figure 10 , Figure 11 As shown, multiple second horizontal tubes 32 and multiple third horizontal tubes 33 are provided between the two connecting arms 1. The second horizontal tubes 32 and the third horizontal tubes 33 are parallel to the first horizontal tube 3. The second horizontal tubes 32 are located above the first horizontal tube 3, and two second horizontal tubes 32 are set corresponding to one first horizontal tube 3. The two second horizontal tubes 32 are symmetrically arranged with the first horizontal tube 3 as the center. The end of the second horizontal tube 32 is fixedly connected to the end of the first horizontal tube 3 through the first support rod 34.

[0078] The third horizontal tube 33 is located directly above the second horizontal tube 32, and the end of the third horizontal tube 33 is fixedly connected to the end of the second horizontal tube 32 by the second support rod 35.

[0079] In this way, the first horizontal tube 3, the second horizontal tube 32 and the third horizontal tube 33 can support three sets of cables 10 respectively, so as to realize the spacing of multiple sets of cables 10 in the height direction and reduce the occurrence of cable 10 stacking.

[0080] Furthermore, the first horizontal tube 3 is rotatably connected to the connecting arm 1 around its own axis, and a toothed ring 36 is fixed at the end of the first horizontal tube 3. The toothed ring 36 is located in the inner cavity of the connecting arm 1, and the toothed ring 36 has a toothed segment 37 that is one-twelfth of a circumference.

[0081] The second ventilation pipe head 56 has clearance slits 561 at both ends, and the inner wall of the second ventilation pipe head 56 is integrally formed with a rubber toothed rack 562, which meshes with the toothed segment 37 of the toothed ring 36.

[0082] When the mobile air circulation mechanism 20 moves, the second ventilation duct head 56 first collides with the protruding toothed ring 36. By avoiding the cutting slit 561 and the deformation of the second ventilation duct head 56 itself, the cutting slit 561 is opened, and the toothed ring 36 can enter the second ventilation duct head 56. The mobile air circulation mechanism 20 continues to move, and the rack 562 on the second ventilation duct head 56 meshes with the tooth segment 37 of the exposed toothed ring 36 of the first horizontal pipe 3, so as to drive the first horizontal pipe 3 to rotate 30°. The first horizontal pipe 3 drives the second horizontal pipe 32 and the third horizontal pipe 33 to rotate together, thereby partially lifting the upper two sets of cables 10, so as to increase the vertical distance of the cables 10 at this local position (the position of the cables 10 directly opposite the exhaust square pipe 53), thereby increasing the fresh air passage, improving the heat dissipation effect, and reducing the occurrence of heat accumulation.

[0083] Example 5 The difference between Example 5 and Example 1 is that, as Figure 12 As shown, the housing 5 is provided with a water tank 57, which is located on one side of the air outlet end of the fan assembly 6. The water tank 57 is provided with a ceramic atomizing plate 58. The housing 5 is also provided with a water inlet 61 and a sealing plug 62 for opening and closing the water inlet 61, so as to replenish water to the water tank 57.

[0084] When heat dissipation is required, low-temperature water can be added to the water tank 57 in advance through the water inlet 61. Then, the high-frequency vibration of the ceramic atomizing plate 58 is used to atomize the low-temperature water. The low-temperature fresh air is then delivered to the vicinity of the cable 10 through the fan assembly 6, which greatly reduces the temperature of the cable 10 and improves the heat dissipation effect.

[0085] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application.
