Description

Technical Field

[0001] The present application relates to the field of AI technology, and in particular to an AI edge computing terminal box. Background Art

[0002] AI edge computing terminal box (also often referred to as edge computing box or AI algorithm box) is an intelligent device that integrates artificial intelligence and edge computing technologies. It has the ability to process, store and respond to data in real time, and has significant advantages in providing efficient data processing and real-time response. With the rapid development of 5G and AI technologies, AI edge computing terminal boxes have been applied to a variety of practical scenarios, such as supporting the linkage control of smart home devices to achieve real-time monitoring and intelligent management; applied in the industrial field, used for real-time monitoring and analysis of data in the production environment, improving production efficiency and quality control; applied in smart communities, it can be used for pedestrian detection, manhole cover recognition, phone calls and smoking detection, etc., to improve community management and service levels.

[0003] However, with the rapid development of AI technology, the computing power requirements of edge computing terminal boxes are constantly rising, resulting in increasingly prominent heat dissipation issues. On the one hand, high-performance AI chips generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will not only affect the stable operation of the equipment, but may also shorten its service life and restrict the further growth of AI computing power. On the other hand, since edge computing terminal boxes need to be deployed close to the data source, their heat dissipation performance will become an important factor affecting the stability of the data source.

[0027] Combine the following Figures 1 to 8 Embodiments of the present application are described in detail, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0028] In the description of the present application, it should be understood that if the terms "center", "middle", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "axial", "radial", "circumferential" and the like appear, the orientation or position relationship indicated is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the present application and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present application. In addition, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present application, unless otherwise specified, "multiple" means two or more.

[0029] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0030] According to relevant statistics, with the development of the Internet of Things and the popularization of 5G technology, by 2025, the number of connected IoT devices will reach 100 billion worldwide. The massive amount of computing data makes the cloud computing method of transmitting to the cloud for processing even more stretched. Edge computing with low latency, real-time processing, scalability and higher security has emerged. The AI ​​edge computing box is a small device that integrates artificial intelligence technology, which is designed to perform efficient and real-time data processing at the source of data generation, providing faster and more efficient computing and analysis capabilities. Its main functional features include the ability to process data and run algorithms close to the user, reduce latency, and improve privacy protection; it has the characteristics of high computing power, low power consumption, and multiple interfaces, and supports multiple functions such as face recognition, passenger flow analysis, and intelligent video analysis; it can aggregate rich AI algorithms, support multiple protocol docking, provide API interfaces and third-party platform docking, and is flexible, lightweight, and easy to deploy. It changes the way of processing and analyzing data, brings computing resources closer to the data source, and performs computing at close range of the device, thereby achieving faster data processing, real-time analysis, and reducing network latency, solving data processing problems in multiple fields such as smart cities, smart energy, smart security, and smart retail.

[0031] The transfer of computing power core equipment from traditional CPU to GPU not only improves computing efficiency, but also enables complex data processing and deep learning models. However, high-performance AI chips will generate a lot of heat during operation. If the heat cannot be dissipated in a timely and effective manner, it will not only affect the stable operation of the equipment, but also shorten its service life, restricting the further growth of AI computing power. In the future, the thermal design power consumption of a single high-performance AI chip will exceed 1000W, reaching the limit of traditional air-cooled heat dissipation. To this end, for AI computing boxes, most of the existing technologies use heat dissipation fins on one side of the shell to improve heat dissipation efficiency and reduce the damage to components caused by high heat caused by high-load operation. However, in actual use, the box often needs to be placed on an installation surface. Whether it is a horizontal desktop or a vertical wall or device connection surface, the bottom connection surface of the box will be blocked, which will cause the heat dissipation of the box to mainly rely on the side with heat dissipation fins, and the heat dissipation efficiency is not high.

[0032] See also Figure 1 , Figure 1 The figure is a structural diagram of an AI computing box in the prior art. Currently, based on the traditional single-sided heat sink fins, an AI box with heat sink fins on both sides has been developed. As shown in the figure, heat conductors are provided on both sides of the AI ​​box body to absorb the heat of the AI ​​box body and dissipate it to the external environment, thereby improving the heat dissipation effect of the AI ​​box body. However, in actual application, the AI ​​box is placed horizontally for use, and one side of the heat conductor will directly contact the desktop or other installation surface, so that the heat sink on this side cannot dissipate heat to the external environment normally, resulting in reduced heat dissipation efficiency. In other words, even if the AI ​​box is provided with heat sinks on both sides, the heat sink on one side cannot be used normally, and the heat dissipation effect is not much improved compared to the AI ​​box with a heat sink on one side.

[0033] Based on this, see Figure 2-Figure 8 An AI edge computing terminal box provided in an embodiment of the present application includes a box body 1, a first heat dissipation structure 11 is provided on one side of the box body 1; a heat dissipation support structure 2, the heat dissipation support structure 2 is provided on the other side opposite to the first heat dissipation structure and is connected to the box body 1, for supporting the box body 1; the heat dissipation support structure 2 includes a mounting plate 21 and a second heat dissipation structure 20, the box body 1, the mounting plate 21 and the second heat dissipation structure 20 are connected in sequence, the second heat dissipation structure 20 includes a first heat dissipation fin 22 and a second heat dissipation fin 23, the first heat dissipation fin 22 and the second heat dissipation fin 23 are spaced apart and connected by a first connecting rod 25, and the spacing distance between the first heat dissipation fin 22 and the second heat dissipation fin 23 can be adjusted by the first connecting rod 25.

[0034] It can be understood that the box body 1 at least includes a processing unit, storage and memory, and a variety of interface resources; the processing unit refers to the AI ​​edge computing terminal box equipped with a high-performance CPU (central processing unit) and GPU (Graphic Processing Unit). The CPU is responsible for processing various instruction executions and data processing, and the GPU is responsible for performing complex mathematical and geometric calculations to render images, videos and other graphic content. It adopts a large-scale parallel hardware architecture and can execute thousands of threads at the same time, greatly improving the ability of graphics rendering and data parallel computing; CPU and GPU are common such as NVIDIA Jetson Xavier NX or RK3588 chips, providing powerful computing power and AI computing power, supporting real-time data processing and intelligent analysis. Storage and memory refer to being equipped with sufficient memory and storage space, such as 12GB LPDDR4x memory and 32GB eMMC storage, to ensure the smoothness of system operation and data storage needs; interface resources can include Gigabit network port, USB interface, HDMI, CAN, RS485, etc., as well as wireless communication functions such as 5G / 4G, WiFi, to meet various peripheral connection and communication needs. In this embodiment, the detailed structure of the box body 1 is not described in detail, and those skilled in the art should understand that the box body 1 of this embodiment has the basic functions of an AI computing box.

[0035] For example, see Figure 2-Figure 8 The first heat dissipation structure 11 can be a heat dissipation fin structure. The heat dissipation fin is a plurality of grooves provided on the upper surface of the box body 1, so that the surface area of ​​the box body 1 in contact with the external environment is increased, thereby increasing the heat dissipation effect. The first heat dissipation structure 11 can be an integrated structure with the box body 1, that is, it is provided when the box body 1 is manufactured, avoiding the addition of additional components at a later stage, which may affect the heat dissipation. The first heat dissipation structure 11 and the outer shell of the box body 1 can be made of a lightweight alloy material, such as an aluminum alloy material, which has high strength, high temperature resistance, and good heat dissipation performance.

[0036] Further, see Figure 2 and Figure 4, the box body 1 includes two sides with larger areas, the first heat dissipation structure 11 is arranged on one of the sides, and the heat dissipation support structure 2 is arranged on the other side opposite to the first heat dissipation mechanism and connected to the box body 1. Since the AI ​​edge computing terminal box needs to be adjacent to or fixed to other devices during actual installation and use, the side with a larger area is often covered, so that the heat dissipation area of ​​the surface is wasted. In this embodiment, the second heat dissipation structure 20 is fixedly connected to the box body 1 through the mounting plate 21 and is arranged on the side opposite to the first heat dissipation structure 11, making full use of the heat dissipation area of ​​the box body 1. Specifically, the second heat dissipation structure 20 includes a first heat sink 22 and a second heat sink 23, the first heat sink 22 and the second heat sink 23 are spaced apart and connected by a first connecting rod 25, the first heat sink 22 is arranged adjacent to the mounting plate 21, and the second heat sink 23 is arranged away from the mounting plate 21. The first connecting rod 25 can be a screw or a connecting rod with multiple locking positions. The distance between the first heat sink 22 and the second heat sink 23 can be flexibly adjusted through the first connecting rod 25. By setting the first heat sink 22 and the second heat sink 23, the box body 1 can be prevented from directly abutting against other devices or installation surfaces, and the interval between the first heat sink 22 and the second heat sink 23 provides heat dissipation space for the box body 1.

[0037] A second heat dissipation structure 20 is provided on the side of the AI ​​edge computing terminal box opposite to the first heat dissipation structure 11, and the second heat dissipation structure 20 is provided with a first heat dissipation fin 22 and a second heat dissipation fin 23 with an adjustable distance therebetween. When the AI ​​edge computing terminal box is connected to an external device or a connection surface, the second heat dissipation structure 20 is provided between the box body and the external device, and the first heat dissipation fin 22 and the second heat dissipation fin 23 with a spacing distance ensure that the box body 1 can dissipate heat through the first heat dissipation structure 11 as well as through the second heat dissipation structure 20, thereby greatly improving the heat dissipation area and heat dissipation efficiency of the AI ​​edge computing terminal box, and achieving excellent heat dissipation effect.

[0038] In certain embodiments of the present application, see Figure 2-Figure 6A plurality of elastic heat-conducting sheets 24 are arranged between the first heat sink 22 and the second heat sink 23, and both ends of the elastic heat-conducting sheets 24 are fixedly connected to the first heat sink 22 and the second heat sink 23 respectively. When the distance between the first heat sink 22 and the second heat sink 23 becomes smaller, the elastic heat-conducting sheets 24 are compressed; when the distance between the first heat sink 22 and the second heat sink 23 becomes larger, the elastic heat-conducting sheets 24 are stretched. At this time, the elastic heat-conducting sheets 24 can restore their shape through their own elasticity while supporting the increase in the distance between the first heat sink 22 and the second heat sink 23. Exemplarily, the elastic heat conductive sheet 24 can be a heat conductive corrugated sheet made of alloy material. On the one hand, the elastic heat conductive sheet 24 serves as a supporting structure between the first heat sink 22 and the second heat sink 23, so that when the AI ​​edge computing terminal box is placed flat, the heat dissipation support structure 2 is pressed under the AI ​​edge computing terminal box, and the heat dissipation support structure 2 can provide support for the AI ​​edge computing terminal box. The elastic heat conductive sheet 24 ensures that the first heat sink 22 and the second heat sink 23 will not be directly compressed to no gap; on the other hand, the elastic heat conductive sheet 24 has good thermal conductivity. After being connected to the first heat sink 22, it can conduct heat from the first heat sink 22, further improving the heat dissipation effect. By arranging the first heat sink 22 and the second heat sink 23 at the bottom of the box body 1 and supporting them through the heat conductive elastic sheet, the air flow space at the bottom of the box body 1 is expanded, and the heat dissipation area is increased. Compared with the existing box body 1 with a bottom closed design, the heat dissipation efficiency is higher, and the stable operation of the components in the box body 1 can be ensured.

[0039] Further, see Figure 2 , Figure 4-Figure 5 , the middle part of the elastic heat conductive sheet 24 is bent, and the two adjacent elastic heat conductive sheets 24 are symmetrically arranged. For example, a plurality of elastic heat conductive sheets 24 are evenly spaced and arranged between the first heat sink 22 and the second heat sink 23. Arranging the elastic heat conductive sheet 24 into a bent shape in the middle can control the compression direction of each elastic heat conductive sheet 24 when subjected to pressure, thereby making the first heat sink 22 and the second heat sink 23 more stable, and the symmetrically arranged elastic heat conductive sheets 24 have a more uniform force distribution when supporting the first heat sink 22, and will not cause the box body 1 to tilt to one side, which is safer and more reliable.

[0040] In certain embodiments of the present application, see Figure 2-Figure 6 The first connecting rod 25 extends from the second heat sink 23 toward the first heat sink 22 and passes through the first heat sink 22. A knob is provided at the end of the first connecting rod 25 facing the first heat sink 22. The first connecting rod 25 is also sleeved with a first return spring 27 arranged between the first heat sink 22 and the second heat sink 23. Turning the knob can be used to adjust the spacing distance between the first heat sink 22 and the second heat sink 23.

[0041] It can be understood that the first connecting rod 25 extends from the second heat sink 23 toward the side of the first heat sink 22, that is, the first connecting rod 25 does not penetrate the second heat sink 23, and is abutted or fixedly connected to the second heat sink 23. The first connecting rod 25 is movably connected to the knob after passing through the second heat sink 23, and the first connecting rod 25 is sleeved with a first return spring 27 between the first heat sink 22 and the second heat sink 23. When the knob is turned toward the second heat sink 23, the length of the first connecting rod 25 between the first heat sink 22 and the second heat sink 23 can be reduced, that is, the spacing distance between the first heat sink 22 and the second heat sink 23 can be reduced. At this time, the second heat sink 23 moves toward the first heat sink 22, and the first return spring 27 is compressed at the same time. At this time, the installation height of the box body 1 can be reduced, and the application scenario of the AI ​​edge computing terminal box can be increased; when the knob is turned toward the first heat sink 22, the first return spring 27 provides a supporting force to open the first heat sink 22 and the second heat sink 23, thereby restoring the spacing distance between the first heat sink 22 and the second heat sink 23.

[0042] In certain embodiments of the present application, see Figure 2-Figure 6 Corresponding mounting holes 28 are provided at the four corners of the mounting plate 21, the first heat sink 22 and the second heat sink 23. A second connecting rod 29 is inserted into the mounting hole 28. The second connecting rod 29 is sleeved with a second return spring 210 arranged between the first heat sink 22 and the second heat sink 23. The second connecting rod 29 is used to connect the box body 1 to an external device.

[0043] Exemplarily, the second connecting rod 29 can be a bolt with a nut at one end. The second connecting rod 29 passes through the mounting holes 28 of the mounting plate 21, the first heat sink 22, and the second heat sink 23 in sequence. The end with the nut is located on the outside of the mounting plate 21, and the size of the nut is smaller than the size of the mounting hole 28, so that the second connecting rod 29 cannot pass through the mounting hole 28 as a whole. The second return spring 210 set between the second connecting rod 29 and the first heat sink 22 and the second heat sink 23 is used to support the first heat sink 22 and the second heat sink 23. When installing the AI ​​edge computing terminal box, the four second connecting rods 29 are inserted into the mounting hole 28 and fixed on the screw holes reserved on the connection surface of the wall or the device. When the second connecting rod 29 is rotated, the first heat sink 22 and the second heat sink 23 are squeezed, so that the second heat sink 23 is closely attached to the connection surface to ensure stable connection. At this time, the second return spring 210 set on the second connecting rod 29 is also compressed, thereby providing support and stabilizing the box body 1, and will not tilt to one side. When the first heat sink 22 and the second heat sink 23 are provided with an elastic heat conductive sheet 24 , the second return spring 210 can reduce the loss of the elastic heat conductive sheet 24 when the first heat sink 22 and the second heat sink 23 are compressed.

[0044] In certain embodiments of the present application, see Figure 5 , the mounting plate 21 is fixedly connected to the first heat sink 22, and a thermal conductive material layer 211 is provided between the mounting plate 21 and the first heat sink 22. Exemplarily, to further ensure stable heat dissipation, the mounting plate 21 and the first heat sink 22 can be fixedly connected by bonding, and a layer of thermal conductive material layer 211 pre-coated between the mounting plate 21 and the first heat sink 22 can fill the gap between the two, ensuring that heat can be fully conducted out from the mounting plate 21, thereby ensuring the heat dissipation effect. Specifically, the thermal conductive material can be thermal conductive silicone grease, thermal conductive gel, thermal conductive adhesive, etc., which can fill the micro gaps and uneven surfaces generated when the mounting plate 21 and the first heat sink 22 are in contact, so as to reduce thermal resistance and help form a good thermal conductive channel to reduce the thermal resistance of heat dissipation.

[0045] In certain embodiments of the present application, see Figure 4 At least two support bars 212 are arranged on the outer wall of the second heat sink 23 away from the first heat sink 22, and the surface of the support bar 212 is uneven. The support bar 212 is arranged at the bottom of the AI ​​edge computing terminal box installation, which can ensure that the box body 1 is placed stably. The support bar 212 supports the second heat sink 23, so that there is a certain heat dissipation gap at the bottom of the second heat sink 23 to ensure heat dissipation, and the uneven surface of the support bar 212 is set as an anti-slip setting to ensure that the box body 1 will not fall and slip easily when placed on a plane, thereby protecting the box body 1.

[0046] The AI ​​edge computing terminal box provided in this embodiment is used by aligning the protruding end of the first connecting rod 25 on the first heat sink 22 toward the mounting plate 21, and then putting the knob 26 on the first connecting rod 25 and rotating it. According to the environment and the size of the space, the first heat sink 22 can be pressed down by turning the knob 26 to make the elastic heat conductive sheet 24 slightly contract, so that the distance between the first heat sink 22 and the second heat sink 23 is reduced, thereby reducing the installation height of the box body 1. When the knob 26 is turned in the opposite direction, the elastic heat conductive sheet 24 will rebound slightly, so that the distance between the first heat sink 22 and the second heat sink 23 is expanded, thereby increasing the installation height of the box body 1. The box body 1 is highly practical. By arranging the first heat sink 22 and the second heat sink 23 at the bottom of the box body 1 and supporting them with the elastic heat conductive sheet 24, the air flow space at the bottom of the box body 1 is expanded, and the heat dissipation area is increased. Compared with the existing box body 1 with a bottom closed design, the heat dissipation efficiency is higher, and the stable operation of the components in the box body 1 can be ensured.

[0047] In certain embodiments of the present application, see Figure 2-Figure 8The AI ​​edge computing terminal box also includes a dust cleaning structure 3, which is arranged on one side of the first heat dissipation structure 11. The dust cleaning structure 3 is used to clean the first heat dissipation structure 11 to prevent dust from accumulating on the first heat dissipation structure 11 and affecting heat dissipation. The dust cleaning structure 3 includes two slide grooves 31 arranged on two opposite outer side walls of the box body 1 and a sliding frame 34 installed on the two slide grooves 31. The sliding frame 34 is mounted on the first heat dissipation structure 11. The sliding frame 34 is provided with a brush strip 36 facing the first heat dissipation structure 11. When the sliding frame 34 moves back and forth in the slide groove 31, the sliding frame 34 drives the brush strip 36 to clean back and forth on the surface of the first heat dissipation structure 11. It can be understood that the two slide grooves 31 are arranged in corresponding positions, and the two ends of the sliding frame 34 are respectively installed on the two slide grooves 31, and the sliding frame 34 can reciprocate along the slide groove 31. Exemplarily, a penetrating installation groove 35 is opened on the sliding frame 34, and the brush strip 36 is connected to the sliding frame 34 through the installation groove 35 and the brush strip 36 faces the first heat dissipation structure 11. As mentioned above, the first heat dissipation structure 11 is a heat dissipation fin having a plurality of groove structures, and the brushes on the brush strip 36 correspond to the heat dissipation fins. When the sliding frame 34 reciprocates along the sliding groove 31, the brush strip 36 is driven to reciprocate to clean the first heat dissipation structure 11, thereby cleaning the dust hidden in the heat dissipation fins, preventing dust accumulation from hindering the heat dissipation of the first heat dissipation structure 11, ensuring that the first heat dissipation structure 11 can always dissipate heat efficiently, and ensuring the stable operation of the components in the box body 1.

[0048] In certain embodiments of the present application, see Figure 2 and Figure 4 The cleaning structure 3 also includes a reciprocating screw 33, which is installed in the slide groove 31 and movably connected to the slide groove 31. The sliding frame 34 is screwed to the reciprocating screw 33. A driving motor 32 is provided on at least one slide groove 31. The output end of the driving motor 32 is transmission-connected to the reciprocating screw 33. The driving motor 32 drives the sliding frame 34 to reciprocate through the reciprocating screw 33. It is understandable that the reciprocating screw 33 can rotate on its own axis in the slide slot 31. When the output end of the drive motor 32 is connected to the reciprocating screw 33, the reciprocating screw 33 can be driven to rotate. The sliding frame 34 is screwed to the reciprocating screw 33, which means that the lower end of the sliding frame 34 is movably connected to the reciprocating screw 33 by the meshing force between the threads. When the reciprocating screw 33 rotates, since the reciprocating screw 33 does not move relative to the slide slot 31, the sliding frame 34 will be driven to move in one direction; when the reciprocating screw 33 rotates in the opposite direction, the sliding frame 34 will be driven to move in the opposite direction, thereby realizing the reciprocating motion of the sliding frame 34. In this embodiment, a drive motor 32 is provided at the end of any slide slot 31. It is understandable that the drive motor 32 is also equipped with components such as a switch, a power supply, and a circuit to realize the normal operation of the drive motor 32, which will not be repeated here.

[0049] In certain embodiments of the present application, see Figure 2-Figure 3 , Figure 7-Figure 8 ,,An anti-slip sheet 37 is connected to the outer side of the brush strip 36, and fixing sheets 38 are provided at both ends of the anti-slip sheet 37. The anti-slip sheet 37 is arranged on the outer wall of the sliding frame 34 and is fixedly connected to the sliding frame 34 through the fixing sheets 38. It can be understood that the anti-slip sheet 37 is used to fix the brush strip 36 on the sliding frame 34, and it will not fall off easily during the reciprocating motion. Specifically, after the brush strip 36 passes through the mounting groove 35, it is clamped in the mounting groove 35, and then the anti-slip sheet 37 is covered on the mounting groove 35, and the fixing sheets 38 at both ends of the anti-slip sheet 37 are fixedly connected to the sliding frame 34, thereby fixing the brush strip 36. The fixing sheet 38 can be fixedly connected to the sliding frame 34 by bolts 39 or screws.
