Description

Technical Field

[0001] This invention relates to the field of industrial Internet of Things (IoT) equipment technology, and more specifically to an industrial IoT control box with high-efficiency heat dissipation. Background Technology

[0002] Industrial IoT control boxes are core devices that integrate electronic components such as controllers, communication modules, and power supplies, and are widely used in various industrial environments. With increasing integration and computing power, the heat generated by these internal electronic components increases dramatically. If this heat cannot be dissipated in time, it will lead to excessively high internal temperatures, affecting component performance and lifespan, and even causing system failures.

[0003] Existing industrial IoT control boxes typically employ forced air cooling by creating ventilation holes on the box body and using fans. However, this cooling method has the following problems: First, the airflow directly impacts the surface of the control box body, which can easily create high-speed airflow zones in some areas, while forming vortices or dead zones in other areas, resulting in uneven heat dissipation; second, dust can easily enter the box through the ventilation holes, affecting the reliability of electronic components; finally, for some control boxes that generate a lot of heat, simple air cooling is insufficient to meet the heat dissipation requirements. Summary of the Invention

[0004] In view of the above-mentioned shortcomings of the existing technology, the present invention provides an industrial IoT control box with high-efficiency heat dissipation, which can effectively optimize airflow organization and improve heat dissipation efficiency and uniformity.

[0005] To achieve the above objectives, the present invention provides the following technical solution: including: An outer casing, the interior of which is used to house the control box body, and a cooling interlayer is formed between the inner wall of the outer casing and the outer wall of the control box body; An air inlet, located on the outer casing, is used to introduce cooling airflow; An air outlet is provided on the outer casing to discharge the airflow from the cooling jacket. An air pump, the air outlet of which is connected to the air inlet, is used to deliver cooling airflow into the cooling jacket; A flow guiding assembly, disposed within the cooling interlayer, includes a flow guiding plate and an elastic hinge. One edge of the flow guiding plate is mounted to the inner wall of the outer casing via the elastic hinge, allowing the flow guiding plate to swing around the edge under the impact of the cooling airflow, and the elastic hinge provides an elastic force to reset the flow guiding plate.

[0006] Preferably, the guide vane includes a main body and a bent portion disposed at the free end of the main body, the bent portion being bent toward the outer wall of the control box body and having a gap between it and the outer wall of the control box body.

[0007] Preferably, the flow guiding assembly includes a plurality of flow guiding plates, which are spaced apart along the length of the cooling interlayer, and the elastic hinges of two adjacent flow guiding plates are symmetrically arranged so that the two adjacent flow guiding plates swing in opposite directions under the impact of airflow.

[0008] Preferably, the elastic hinge includes a rigid connecting part fixedly connected to the guide plate and an elastic sheet connected to the rigid connecting part. The elastic sheet is fixed to the inner wall of the outer casing, and the cross-section of the elastic sheet is arc-shaped with the apex of the arc facing the airflow direction.

[0009] Preferably, the surface of the guide vane is provided with a plurality of micro protrusions, which are conical blocks used to disturb the airflow during the swinging of the guide vane.

[0010] Preferably, the airflow guiding components are provided in the four side walls of the outer casing to comprehensively cool the four outer walls of the control box body.

[0011] Preferably, the cooling interlayer further includes a top interlayer located above the control box body, and a top guide plate is rotatably disposed in the top interlayer. The guide vanes located at the edge of the cooling interlayer are connected to the top guide plate through a flexible connecting rod so as to drive the top guide plate to rotate synchronously when the guide vanes swing.

[0012] Preferably, the guide vane and the rigid connection part are eccentrically connected, so that the guide vane has a composite motion trajectory of horizontal swing and vertical rise and fall under the impact of airflow.

[0013] Preferably, the elastic hinges of the airflow guiding components on two adjacent side walls of the outer casing have different elastic coefficients, causing the airflow guiding plates on the adjacent side walls to swing in opposite directions, thereby forming a spiral upward airflow within the cooling interlayer.

[0014] Preferably, the guide vane is made of a composite of flexible elastic material and rigid frame, the micro protrusion is a retractable structure, and the guide vane can generate adaptive bending deformation under different airflow pressures to guide the airflow to the top area of ​​the control box body.

[0015] The technical solution provided by this invention has the following advantages compared with the known prior art: 1. By setting up an outer casing and forming a cooling interlayer between its inner wall and the outer wall of the control box body, isolated heat dissipation of airflow and internal components is achieved, effectively preventing dust intrusion; by setting a flow guiding component consisting of guide vanes and elastic hinges in the cooling interlayer, the guide vanes can continuously swing under the impact of airflow, realizing dynamic disturbance of airflow, eliminating heat dissipation dead zones, and significantly improving the uniformity and efficiency of heat dissipation.

[0016] 2. By arranging multiple guide vanes at intervals and symmetrically setting the elastic hinges of adjacent guide vanes, the effect of adjacent guide vanes swinging alternately in opposite directions under the impact of airflow is achieved, forming a cross-sweeping airflow disturbance mode, which enhances the mixing and turbulence intensity of the airflow, thereby further strengthening the heat exchange effect.

[0017] 3. By installing flow guide components in all four side walls of the outer casing, the control box body's outer walls are fully cooled. Furthermore, by setting the elastic hinges of adjacent side wall flow guide components to different elastic coefficients, the adjacent side wall flow guides are made to swing in opposite directions, thereby inducing a spiral upward airflow in the cooling interlayer, extending the heat exchange path, and significantly improving the overall heat dissipation effect.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0022] The present invention will be further described below with reference to embodiments.

[0023] Example 1: Refer to Figures 1 to 4 An efficient heat dissipation industrial IoT control box is provided, which includes: an outer casing 1, a control box body 2, an air inlet 4, an air outlet 5, an air pump 6, and a flow guiding component 7 disposed in a cooling jacket 3.

[0024] Specifically, such as Figures 1-4 As shown, the distinguishing technical feature of the sovereign is the structure of the flow guide assembly 7, which includes a flow guide plate 8 and an elastic hinge 9. One side edge of the flow guide plate 8 is mounted to the inner wall of the outer casing 1 by the elastic hinge 9, so that the flow guide plate 8 can swing around the edge under the impact of the cooling airflow, and the elastic hinge 9 provides an elastic force to reset the flow guide plate 8.

[0025] During operation, the air pump 6 delivers cooling airflow into the cooling jacket 3 through the air inlet 4. The airflow impacts the guide vane 8, causing it to oscillate, thereby dynamically changing the airflow direction and guiding the airflow to the outer wall of the control box body 2 to achieve efficient convective heat transfer. When the airflow speed decreases or stops, the elastic hinge 9 resets the guide vane 8.

[0026] Furthermore, such as Figure 4 As shown, the guide vane 8 also includes a bent portion 10 disposed at the free end of its main body. The bent portion 10 bends toward the outer wall of the control box body 2 and has a gap with the outer wall of the control box body 2. When the airflow is guided to the surface of the control box body 2 by the main body of the guide vane 8, the bent portion 10 can further "press" the airflow near the wall, guide the airflow to flow close to the wall, prolong the heat exchange time and path, and achieve a better wall-adhering cooling effect.

[0027] Furthermore, such as Figure 4 As shown, the airflow guiding assembly 7 includes multiple airflow guiding vanes 8, which are spaced apart along the length of the cooling jacket 3, and the elastic hinges 9 of adjacent airflow guiding vanes 8 are symmetrically arranged. This symmetrical arrangement causes adjacent airflow guiding vanes 8 to swing in opposite directions when impacted by airflow from the same direction, causing the airflow from adjacent airflow guiding vanes 8 to collide and shear each other, forming local vortices and strong turbulence within the cooling jacket 3. The heat transfer efficiency of the airflow under this turbulent state is much higher than that of laminar flow.

[0028] Furthermore, such as Figure 5 As shown, the elastic hinge 9 includes a rigid connecting part 14 fixedly connected to the guide vane 8 and an elastic piece 15 connected to the rigid connecting part 14. The elastic piece 15 is fixed to the inner wall of the outer casing 1, and its cross-section is arc-shaped with the arc apex facing the airflow direction. This arc-shaped elastic piece 15 design allows it to produce smooth bending deformation when subjected to airflow pressure, thereby driving the guide vane 8 to swing smoothly. When the airflow pressure decreases, the energy storage effect of the arc-shaped structure can enable the guide vane 8 to quickly and reliably return to its original position. The arc apex facing the airflow direction helps to reduce airflow resistance and improve energy utilization efficiency.

[0029] Furthermore, such as Figure 4 As shown, the surface of the guide vane 8 is provided with multiple micro protrusions 11, which are conical blocks. When the airflow passes over the surface of the guide vane 8, these micro protrusions 11 can continuously disrupt the boundary layer of the airflow and generate tiny vortices, so that the airflow is in a high turbulent state before it reaches the surface of the control box body 2. At the same time, the oscillation of the guide vane 8 makes the turbulence effect of the micro protrusions 11 also dynamically change.

[0030] Furthermore, such as Figure 3 As shown, each of the four side walls of the outer casing 1 is equipped with a flow guiding component 7, so that the cooling airflow delivered by the air pump 6 can simultaneously perform forced convection heat exchange on the four sides of the control box body 2, avoiding heat dissipation dead zones and ensuring the overall temperature uniformity of the control box body 2.

[0031] Furthermore, such as Figure 6 As shown, the cooling interlayer 3 also includes a top interlayer 16 located above the control box body 2. A top surface guide plate 12 is rotatably installed in the top interlayer 16. The guide plate 8 located at the uppermost edge of the cooling interlayer 3 is connected to the top surface guide plate 12 through a flexible connecting rod. When the guide plate 8 at the edge swings under the impact of airflow, it will pull the top surface guide plate 12 to rotate synchronously through the flexible connecting rod, so that the airflow originally used for side cooling can be guided to the top interlayer 16 to cool the top surface of the control box body 2.

[0032] Furthermore, such as Figure 5 As shown, the guide vane 8 and the rigid connection part 14 are eccentrically connected, so that when the guide vane 8 is impacted by the airflow, it will not only swing horizontally around the hinge axis, but also generate a vertical lifting motion due to the shift of the center of gravity. This makes the guiding effect of the guide vane 8 on the airflow change in space, and can more effectively sweep the surface of the control box body 2 without leaving any dead corners.

[0033] Furthermore, the elastic hinges 9 of the flow guide components 7 on the two adjacent side walls of the outer casing 1 are designed to have different elastic coefficients. Due to the different elastic coefficients, the flow guide vanes 8 on the adjacent side walls will have different response speeds and swing amplitudes to the airflow, forming a reverse staggered swing rhythm. This staggered swing forces the airflow to continuously change direction during the upward process, eventually forming a powerful spiral upward airflow in the cooling jacket 3. The spiral airflow prolongs the residence time of the airflow in the cooling jacket 3 on the one hand, and also enhances the convective heat transfer between the airflow and the wall on the other hand.

[0034] Furthermore, the guide vane 8 is made of a composite of flexible elastic material and rigid frame. This structure gives the guide vane 8 a certain degree of flexibility, which can produce adaptive bending deformation under different airflow pressures. At the same time, the micro protrusions 11 are designed as a telescopic structure. When the airflow pressure is high, the guide vane 8 bends a large degree, and the telescopic micro protrusions 11 are compressed or popped out, which can further guide some of the high-pressure airflow to the top area of ​​the control box body 2, which is difficult to reach.

[0035] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the protection scope of the technical solutions of the embodiments of the present invention.
