Description

Technical Field

[0001] The present invention relates to the technical field of cable trays, and particularly to an adaptive heat dissipation cable tray. Background Art

[0002] In the fields of power transmission, data centers, and industrial automation, etc., as an important carrier for cable laying, the heat dissipation performance of cable trays directly affects the operation safety and service life of cables. With the continuous increase of power load and the improvement of cable laying density, if the heat generated by cables during operation cannot be dissipated in time, it is easy to cause cable insulation aging, transmission efficiency decline, and even lead to safety accidents.

[0003] Traditional cable tray heat dissipation methods mostly rely on natural ventilation or simple forced air cooling structures, and there are obvious technical defects: Firstly, the heat dissipation structure design is single, usually only achieving natural convection through the openings on the tray shell. When cables are densely laid, internal heat is easily accumulated, and the heat dissipation efficiency is low; Secondly, there is a lack of effective separation of cables. The centralized placement of multiple cables will exacerbate heat superposition, and traditional limiting structures cannot balance the requirements of heat dissipation and cable fixation; Thirdly, most existing heat dissipation mechanisms are of fixed design and are difficult to adaptively adjust the heat dissipation intensity according to the operating temperature of cables, resulting in energy consumption waste or insufficient heat dissipation; Fourthly, some forced heat dissipation devices are prone to dust accumulation and blockage, with high maintenance costs, and the complex structure affects the installation convenience of the tray.

[0004] In addition, the intake and heat exhaust path designs of traditional trays are unreasonable, the air flow organization is chaotic, and it is difficult to form an efficient heat exchange cycle. Especially in the long-term high-load operation scenario, the heat dissipation efficiency decays significantly. Therefore, how to design a tray structure with adaptive heat dissipation ability, which can effectively separate cables and form an efficient heat dissipation cycle, has become an urgent technical problem in this field.

[0030] Embodiment 1

[0031] This embodiment provides a technical solution: an adaptive heat dissipation cable tray, as Figures 1-7 shown, including a cable tray assembly 1, which includes a lower box body 101 for placing cables and an upper cover 103 covering the top of the lower box body 101.

[0034] Heat Dissipation Component 31: Arranged outside the lower box body 101, it includes a heat sink group 311 and an accelerated heat dissipation unit that are connected to each other. The heat sink group 311 penetrates the outer side wall of the lower box body 101 and is fixedly connected to the fixed plate 301; the accelerated heat dissipation unit is fixedly connected to the bottom end of the heat sink group 311, and includes a heat dissipation pipe 312 and a wind gathering cover 313. Both ends of the heat dissipation pipe 312 are connected to the wind gathering cover 313, and multiple air dispersion holes 314 corresponding to the bottom end are opened on the heat sink group 311.

[0035] Heat Driving Component 32: Arranged below the lower box body 101, it includes a heat driving outer shell 321, multiple second air intake holes 324, multiple heat sink bodies 322, and a wind gathering inner tank 323 that are connected to each other. The heat driving outer shell 321 is fixedly connected to the bottom end of the air guiding plate 309 and is fixedly connected to the bottom end of the lower box body 101; multiple second air intake holes 324 are opened at the inner bottom end of the lower box body 101 and are located outside the air guiding plate 309; multiple heat sink bodies 322 are fixedly connected to the bottom end of the heat driving outer shell 321; the wind gathering inner tank 323 is fixedly connected to the heat driving outer shell 321.

[0036] Heat Exhaust Component 33: Arranged on one of the heat driving components 32, it includes a fan 331, a first gear 332, a second gear 333, and a motor 334 that are connected to each other. The fan 331 is rotatably connected to the outer wall of the cylinder; the first gear 332 is fixedly connected to one side of the fan 331 and is sleeved on the cylinder; the second gear 333 meshes with the first gear 332; the output shaft of the motor 334 is fixedly connected to the second gear 333 and is fixedly connected to the lower box body 101 through a motor fixing plate 335.

[0037] Heat dissipation principle: The first air inlet 102 at the bottom of the lower box body 101 adopts an aperture increasing design, and cooperates with the arc-shaped upper cover 103 to guide the external airflow to form natural convection and accelerate the discharge of hot air inside the bridge. The heat sink group 311 and the heat dissipation pipe 312 and the wind collecting cover 313 of the heat dissipation component 31 are in direct contact with the heating area of the cable. The heat is quickly discharged through the dual mechanisms of metal heat conduction and forced airflow heat dissipation. The inclined layout of the ventilation hole 304, the second air inlet 324 and the air inlet groove 306, plus the guiding effect of the arc-shaped upper cover 103, avoids airflow dead corners and improves heat exchange efficiency. The air inlet groove 306 can balance the heat dissipation air volume of cables in different positions, thereby forming an efficient heat dissipation cycle.

[0038] Principle of cable separation and fixation: The cable limiting groove 303, the card slot 305 and the elastic air induction groove 306 in the installation component 30 form a separation structure, and cooperate with the cable clamp plate 308 made of elastic material and the first limiting cylinder formed in a curved shape to separate multiple cables into layers, thereby reducing the heat superposition effect. The cable clamp plate 308 made of elastic material, the first limiting cylinder formed in a curved shape and the card slot 305 can fit tightly to the outer walls of cables of different diameters, preventing shaking while reserving the gap between the first limiting cylinder and the waist-shaped hole for heat dissipation, thereby realizing adaptive fixation of the cable.

[0039] Principle of structural stability: the lower box body 101, the installation component 30, the heat dissipation component 31 and the heat drive component 32 are an integrated structure, which reduces the number of connectors and the complexity of installation, while ensuring the unity of structural strength and heat dissipation efficiency. The fixing plate 301 and the installation plate 302 are both U-shaped and an integrated structure, which are fixedly connected to the inner wall of the lower box body 101; the air induction plate 309 runs through the bottom end of the lower box body 101 and forms a supporting frame with the heat drive shell 321, which avoids structural deformation under long-term load and ensures the stability of cable laying.

[0040] Adaptive heat dissipation adjustment principle: The motor 334 of the heat dissipation component 33 can be linked to the implicit design of the temperature sensor. Because this method is an existing mature technology, it is not shown in the figure and is not described in detail in the solution. The speed of the fan 331 is automatically adjusted according to the real-time temperature of the cable, which reduces energy consumption at low loads and enhances heat dissipation at high loads to achieve "heat dissipation on demand". The fan 331 heat dissipation component in the heat drive component 32 is driven by the motor 334, and the speed can be adaptively adjusted according to the cable operating temperature or a preset threshold to form an active heat dissipation cycle.

[0041] Embodiment 2

[0042] This embodiment is further optimized on the basis of the first embodiment, and the same parts as the above technical solution will not be repeated here. Figures 3 to 6 As shown, in order to better implement the present invention, the following configuration is particularly adopted:

[0043] Optimize the installation component 30.

[0044] Fixing plate 301 and mounting plate 302: Both are U-shaped, and the top of the mounting plate 302 is arc-shaped. This shape design is beneficial to the flow of air, further improving the heat dissipation effect.

[0045] Cable slot 305 and air guiding slot 306: Both are made of elastic material, with flanges provided at both ends of the top. And the air guiding slot 306 is arc-shaped, and the lengths of multiple air guiding slots 306 are different. The use of elastic material enables the cable slot 305 to better adapt to cables with different diameters. The flange design increases the structural stability and facilitates cable installation. The arc-shaped air guiding slot 306 and the different lengths are beneficial to more evenly guide the air flow.

[0046] Cable clamping plate 308: Made of elastic material, bent, with a flange provided at one end away from the cable perforation 307. Multiple cable clamping plates 308 form a first limiting cylinder. The elastic material and the bent design enable the cable clamping plate 308 to closely fit the outer wall of cables with different diameters. The flange design increases the stability of the limiting cylinder and facilitates cable threading.

[0047] Air guiding plate 309: Set in a slope shape, which is beneficial to guiding the air flow to be discharged through the heat dissipation component 32 and also facilitates guiding the air flow into the box body 101.

[0048] Optimize the heat dissipation component 32.

[0049] Heat dissipation outer shell 321: U-shaped, with an inclined bottom. This shape design is beneficial to heat discharge and gas collection.

[0050] Air concentrating inner liner 323: Composed of a funnel-shaped box body and a cylinder inside. The funnel-shaped box body is fixedly connected to the outer end of the heat dissipation outer shell 321. The design of the funnel-shaped box body can reduce dust accumulation and facilitate the gathering of natural wind. With the cooperation of the second air inlet hole 324, it guides the air flow to dissipate heat from the cable when the heat dissipation component 32 is not started.

[0051] Other optimizations: The lower box body 101, installation component 30, heat dissipation component 31 and heat dissipation component 32 are an integrated structure, further improving the structural strength and heat dissipation efficiency.

[0052] Optimization of heat dissipation principle: Due to the shape optimization of the installation component 30 and the heat dissipation component 32, the air flow is more smooth, and the heat exchange efficiency is further improved. The elastic cable slot 305 can better adapt to the heat expansion of the cable and cables with different diameters, maintaining a good heat dissipation gap. The air guiding slot 306 is beneficial to more evenly guide the air flow.

[0053] Optimization of cable separation and fixation principle: The cable slot 305 and cable clamping plate 308 made of elastic materials can better adapt to cables with different diameters and different heating states, achieving more stable separation and fixation while maintaining good heat dissipation gaps.

[0054] Optimization of structural stability principle: The integrated structure design and shape optimization of each component further improve the structural strength and stability of the cable tray, enabling it to better withstand long-term loads.

[0055] Optimization of adaptive heat dissipation regulation principle: Due to the optimization of the heat dissipation structure, the fan 331 can achieve better heat dissipation effects at the same rotation speed, thus further reducing energy consumption while ensuring the heat dissipation effect. The funnel-shaped box design of the air-gathering inner liner 323 can better guide natural airflows to dissipate heat from the cables when the heat dissipation component 32 is not activated, improving the adaptive ability of heat dissipation.

[0056] The above are only the preferred embodiments of the present invention, which are illustrative rather than restrictive to the present invention. Those skilled in the art understand that many changes, modifications, and even equivalents can be made within the spirit and scope defined by the claims of the present invention, but all will fall within the protection scope of the present invention.
