Description

Technical Field

[0001] The present invention relates to the technical field of intelligent power distribution cabinets, and more specifically, to an intelligent power distribution cabinet with temperature warning and feedback. Background Art

[0002] As the core carrier of the end - equipment in the power system, the intelligent power distribution cabinet realizes the remote monitoring and automatic management of electrical components by integrating Internet of Things technology. In current technologies, power distribution cabinets usually adopt distributed temperature sensors or local infrared temperature measurement modules, combined with a control module to trigger a cooling device to achieve early warning of abnormal temperature. The technical logic is that when the local temperature is detected to exceed the threshold, an audible and visual alarm or a linked heat dissipation module is used to prevent component overheating and damage.

[0003] However, the current temperature monitoring system has the problem of monitoring blind spots in the actual working process. Due to the spatial limitations of the traditional sensor layout, generally only single - point sensors can be set on the side wall of the cabinet body. The configured sensors are limited by the fixed viewing angle and cannot cover the entire thermal distribution in a complex wiring environment. When there are multiple layers of electrical components or hidden heat sources inside the power distribution cabinet, the existing solutions are difficult to achieve full - domain temperature perception, which may delay the warning response. For this reason, some technologies try to introduce infrared thermal imaging technology to improve the monitoring accuracy, but due to the equipment deployment method and cost limitations, the problem of full - range coverage has not been solved yet.

[0004] Further analysis reveals that the core contradiction in the current infrared detection system's difficulty in constructing a 360 - degree dead - angle - free monitoring network inside the power distribution cabinet is that the space inside the cabinet is compact. Traditional thermal imagers require a large installation position, resulting in difficult redundant deployment of multiple devices. And the dynamic heat source distribution requires the detection system to have the ability of real - time multi - angle scanning. Currently, most existing solutions rely on statically installed single - point thermal imagers and cannot synchronously capture the temperature gradient changes in three - dimensional space.

[0043] As shown in the figure, in order to clearly show the structure of the embodiments of the present invention, specific structures and devices are marked in the figure, but this is only for schematic purposes and is not intended to limit the present invention to this specific structure, device and environment. Those of ordinary skill in the art can adjust or modify these devices and environments according to specific needs. Detailed implementation manners

[0044] The following describes in detail an intelligent power distribution cabinet with temperature warning feedback provided by the present invention in combination with the accompanying drawings and specific embodiments. At the same time, it should be noted here that in order to make the embodiments more detailed, the following embodiments are the best and preferred embodiments. Those skilled in the art in some well-known technical fields can also implement them in other alternative ways; moreover, the accompanying drawings are only for more specifically describing the embodiments and are not intended to specifically limit the present invention.

[0045] As Figures 1 to 8 shown, an embodiment of the present invention provides an intelligent power distribution cabinet with temperature warning feedback, including a power distribution cabinet body 1 and a wiring component group 2 fixedly installed inside the power distribution cabinet body 1. A first multi-stage regulation mechanism 3 is configured on the top of the power distribution cabinet body 1. The first multi-stage regulation mechanism 3 includes a racetrack-shaped housing 31. A racetrack-shaped guide rail 34 is fixedly connected to the outer edge position of the racetrack-shaped housing 31. A surrounding guide mechanism 4 extending into the power distribution cabinet body 1 is configured on the racetrack-shaped guide rail 34. A plurality of groups of first infrared temperature control units 5 facing the wiring component group 2 are configured on the surrounding guide mechanism 4.

[0046] A first air guide module 36 and a second air guide module 37 are respectively installed at both ends of the racetrack-shaped housing 31. A first servo motor 32 for driving the first air guide module 36 and the second air guide module 37 to rotate and ventilate is configured at the position of the axis of the racetrack-shaped housing 31. A self-start and stop module 38 for connecting the surrounding guide mechanism 4 is also configured on one side of the output end of the first servo motor 32.

[0047] Among them, the self-starting and stopping module 38 controls the connection state between the output end of the first servo motor 32 and the circumferential guiding mechanism 4. When the first air guiding module 36 and the second air guiding module 37 are in the heat dissipation working state, the circumferential guiding mechanism 4 can be connected when the temperature exceeds the warning, and the first infrared temperature control unit 5 is driven to perform 360-degree temperature detection around the wiring component group 2.

[0048] To solve the problem of monitoring blind spots in the existing temperature monitoring system of power distribution cabinets caused by the limited space for sensor layout and the insufficient deployment of static single-point thermal imaging devices, the above technical solution is adopted to solve the problem. The above technical solution mainly consists of a power distribution cabinet body 1, a wiring component group 2, a first multi-stage regulation mechanism 3, and a circumferential guiding mechanism 4. The power distribution cabinet body 1 and the wiring component group 2 are the inherent structures of intelligent power distribution cabinets in the prior art. The power distribution cabinet body 1 is the basic structure of the power distribution cabinet, mainly responsible for protection, support, and integration functions. It is made of cold-rolled steel plate, treated with electrostatic spraying on the surface, with anti-corrosion, dust-proof, waterproof and other properties, and meets the fire protection requirements. The cabinet body is divided into a front panel, side panels, a base, etc. The front panel is provided with switches and indicators for easy operation. High-voltage or low-voltage switchgear is installed on the side panels, and the base provides stable support. The configured wiring component group 2 is a set of electrical components for realizing power distribution, control, and protection in the power distribution cabinet, generally including circuit breakers, busbar systems, control components, measurement and monitoring equipment, etc., to real-time feedback power grid parameters. In the working state, the circuit integration between components is realized through connectors such as busbars and cable joints to form a complete power distribution network.

[0049] Among them, the configured first multi-stage regulation mechanism 3 and the circumferential guiding mechanism 4 are used to form a system for 360-degree temperature monitoring inside the power distribution cabinet body 1. The first multi-stage regulation mechanism 3, as the main regulation structure, can provide a runway-shaped guide rail 34 for the circumferential guiding mechanism 4 to surround the wiring component group 2, so that the circumferential guiding mechanism 4 can stably perform 360-degree temperature monitoring outside the wiring component group 2 along the runway-shaped guide rail 34 to real-time feedback the temperature change at any internal position. The first multi-stage regulation mechanism 3, which is also used as the driving end, on the one hand drives the first air guiding module 36 and the second air guiding module 37 on both sides to rotate, forming a flowing air duct that inhales air from the outside and synchronously discharges hot air outward to neutralize the internal heat and achieve the effect of real-time cooling. On the other hand, the hot air inside is taken away through this flowing air duct, which can also provide a relatively stable monitoring environment for the circumferential guiding mechanism 4, reduce the influence of the internal heat of the system on the heat of a single area, and improve the accuracy of monitoring.

[0050] In the working state, it is only necessary to control the connection state between the output end of the first servo motor 32 and the circumferential guiding mechanism 4 through the self-starting and stopping module 38, that is, by using the effect of magnetic attraction and sticking. When the first air guiding module 36 and the second air guiding module 37 are in the heat dissipation working state, when the temperature exceeds the warning value, the circumferential guiding mechanism 4 can be connected to drive the first infrared temperature control unit 5 to perform 360-degree temperature monitoring around the wiring component group 2, so as to solve the problem of monitoring blind spots in the existing temperature monitoring system of the power distribution cabinet caused by the limited space for sensor layout and the insufficient deployment of static single-point thermal imaging equipment.

[0051] As Figures 1 to 8 shown, a first servo motor 32 is fixedly installed at the bottom center position of the runway-shaped housing 31. The output end of the first servo motor 32 passes through the upper side of the runway-shaped housing 31 and is fixedly installed with a first gear disk 33. Reserved openings 35 penetrating into the interior of the power distribution cabinet body 1 are respectively formed at both side end positions of the runway-shaped housing 31, and a first air guiding module 36 and a second air guiding module 37 are respectively fixedly installed through the reserved openings 35 at both side end positions. The second air guiding module 37 includes a circular ring sleeve 371. A first circular ring groove track 372 is formed on the inner wall of the circular ring sleeve 371, and an embedded circular ring frame 373 is movably installed through the first circular ring groove track 372. A gear outer ring 374 is fixedly installed on the outer edge of the embedded circular ring frame 373.

[0052] Among them, the configured first servo motor 32 is a motor structure capable of servo drive in the prior art and is the core drive execution element in the device, mainly used for converting electrical signals into mechanical motion. It receives instructions from the controller and drives mechanical components to achieve precise displacement, speed or torque output, and there is no self-rotation phenomenon in the working state, which is the prior art. The first gear disk 33 is driven to rotate by the first servo motor 32. The reserved openings 35 formed on both sides of the top of the power distribution cabinet body 1 are for cooperating with the two first air guiding modules 36 and the second air guiding module 37 for heat dissipation.

[0053] As Figures 1 to 8 shown, the structures of the first air guiding module 36 and the second air guiding module 37 composed of the circular ring sleeve 371, the first circular ring groove track 372, the embedded circular ring frame 373, and the gear outer ring 374 are the same, and the gear outer rings 374 on the first air guiding module 36 and the second air guiding module 37 are respectively engaged with both sides of the first gear disk 33. A fan blade group 375 is fixedly installed on the inner wall of the gear outer ring 374 in the second air guiding module 37, and a fan blade group 375 with blades opposite to those of the fan blade group 375 in the second air guiding module 37 is fixedly installed on the inner wall of the gear outer ring 374 in the first air guiding module 36.

[0054] Among them, the overall structures of the configured first air guiding module 36 and the second air guiding module 37 are the same. The difference is that the fan blades of the fan blade group 375 in the first air guiding module 36 are opposite to those of the fan blade group 375 in the second air guiding module 37. The fan blades are set in the opposite structure to form the above-mentioned flow air duct that sucks air from the outside and synchronously discharges hot air outward. Moreover, the first air guiding module 36 and the second air guiding module 37 are not both configured with drive ends, but are driven by the first servo motor 32 at the axial center position of the racetrack-shaped housing 31. The first gear disk 33 at the drive output end of the first servo motor 32 rotates to synchronously drive the gear outer rings 374 engaged on both sides to rotate.

[0055] As Figures 1 to 8 shown, the self-start-stop module 38 includes an electromagnet unit 381 fixedly installed on the upper surface of the first gear disk 33. A circular magnetic attraction sleeve 382 is sleeved on the outer adsorption end of the electromagnet unit 381. A telescopic sliding rod 383 is fixedly connected to the outside of the circular magnetic attraction sleeve 382. A circular orifice sleeve 384 is fixedly connected to the extending end of the telescopic sliding rod 383. A hinged socket rod 385 is movably sleeved on the socket end of the circular orifice sleeve 384, and the hinged socket rod 385 is integrally movably sleeved in the racetrack-shaped guide rail 34. A first high-strength magnetic attraction head 386 that fits on the bottom surface of the racetrack-shaped guide rail 34 is fixedly installed at the bottom of the hinged socket rod 385, and a limit card slot 387 for the first high-strength magnetic attraction head 386 to slide is opened at the inner bottom of the racetrack-shaped guide rail 34.

[0056] Among them, the configured self-start-stop module 38 is to further borrow the driving force at the output end of the first servo motor 32. At the same time, it is also to ensure that in the working state, that is, when the first air guiding module 36 and the second air guiding module 37 are overall dissipating heat, when the temperature exceeds the warning, the surrounding guiding mechanism 4 can be timely connected to drive the first infrared temperature control unit 5 to perform 360-degree temperature detection around the wiring component group 2, improving the coordination of the driving force between the feedback ends. The specific process of borrowing the driving force of the first servo motor 32 by the self-start-stop module 38 is as follows: When it is detected through the air guiding that the hot air exceeds the temperature warning, the adsorption end can be opened through the electromagnet unit 381, so that the adsorption end of the electromagnet unit 381 adsorbs together with the circular magnetic attraction sleeve 382 to form a temporarily integrated structure. As the first gear disk 33 continues to rotate, it will drive the circular magnetic attraction sleeve 382 to rotate synchronously. Since the telescopic sliding rod 383 is connected to the hinged socket rod 385 on the outside of the circular magnetic attraction sleeve 382, the first gear disk 33 can also pull one end of the hinged socket rod 385 to move along the racetrack-shaped guide rail 34, so that it drives the surrounding guiding mechanism 4 at the bottom to perform a surrounding movement.

[0057] The so-called electromagnet unit 381 is an electrically controlled magnet structure in the prior art, an electromagnet device that controls the generation and disappearance of a magnetic field by electric current, and its core is composed of a coil, an iron core, and an armature, and its adsorption end, that is, the outer annular surface and the annular magnetic suction sleeve 382 are adsorbed together by electric current. It can rotate together, or close its adsorption end, that is, the outer annular surface and the annular magnetic suction sleeve 382 do not interfere with each other, and the annular magnetic suction sleeve 382 does not rotate when the electromagnet unit 381 is rotating. The telescopic slide rod 383 is a telescopic rod structure with two sliding sleeves, because the rotation range of the first gear disc 33 is a circle, and the runway-shaped guide rail 34 is a structure similar to a runway shape, so in the process of pulling the articulated sleeve rod 385 by rotating the first gear disc 33, it is necessary to change the length of the pulling end in real time to adapt to the rotation radius of the runway-shaped guide rail 34. The hinged sleeve rod 385 is integrally sleeved inside the runway-shaped guide rail 34 and is movably connected to the telescopic slide rod 383 via a round sleeve ring 384 .

[0058] like Figures 1 to 8 As shown, the surround guide mechanism 4 includes a second high-strength magnetic head 41 adsorbed on the bottom of the first high-strength magnetic head 386 via a runway-shaped guide rail 34, a second servo motor 42 is fixedly installed on the bottom of the second high-strength magnetic head 41, a limit frame 43 is fixedly installed on the bottom of the second servo motor 42, a ball sleeve 6 is movably installed on the bottom of the limit frame 43, a groove for the ball sleeve 6 to slide is provided at the inner bottom of the distribution cabinet body 1, the output end of the second servo motor 42 is passed through the inner top of the limit frame 43, and a threaded rod 44 is fixedly installed on the output end and is integrally placed inside the limit frame 43, and a plurality of first infrared temperature control units 5 are fixedly installed on the side of the surface of the limit frame 43 facing the wiring element group 2.

[0059] Among them, the second high-strength magnetic head 41 is configured with the same structure as the first high-strength magnetic head 386, and both are magnetic head structures in the prior art that can be adsorbed together by high-strength magnetic attraction. Because the runway-shaped guide rail 34 on the runway-shaped shell 31 needs to provide a complete runway-shaped moving path, and it cannot be completed by directly opening a runway-shaped groove, so two magnetic heads are used for adsorption connection, so that the second high-strength magnetic head 41 is adsorbed to the bottom of the first high-strength magnetic head 386 through the bottom surface of the runway-shaped guide rail 34. In order to ensure the stability of the adsorption end, on the one hand, a high-strength magnetic head needs to be used, and on the other hand, the thinness of the bottom surface of the runway-shaped guide rail 34 needs to be ensured.

[0060] The specific working state of the circumferential guiding mechanism 4 is as follows: First, the adsorption end face is opened through the electromagnet unit 381 to form an integral body with the circular magnetic adsorption sleeve 382. Utilizing the rotation of the first gear disk 33 and the adaptive length adjustment function of the telescopic slide rod 383, the articulated socket rod 385 on one side of the circular opening sleeve ring 384 is pulled to rotate inside the runway-shaped guide rail 34. Then, during the movement of the articulated socket rod 385, the first high-strength magnetic adsorption head 386 arranged at its bottom adsorbs the second high-strength magnetic adsorption head 41 at the bottom, causing the limit frame 43 to rotate around the wiring component group 2 inside the power distribution cabinet body 1. During the rotation process, the ball sleeve 6 configured at the bottom of the limit frame 43 can also provide auxiliary supporting force, and the first infrared temperature control unit 5 monitors the temperature of each side position of the wiring component group 2 by using a circumferential movement track.

[0061] Among them, the configured first infrared temperature control unit 5 is a non-contact temperature detection structure in the prior art. Through the infrared radiation energy monitoring function of the non-contact infrared temperature sensor, it monitors the temperature status of each side of the wiring component group 2 in real time, thereby realizing real-time monitoring and overheat warning of the temperature of the equipment inside the power distribution cabinet. It can detect the surface temperature of the wiring components periodically, identify abnormal temperature rises, avoid equipment damage or fire risks caused by line overload or poor contact, and utilize the movement track of the circumferential guiding mechanism 4 to cover multiple angular positions of the wiring component group 2 to achieve full-range temperature scanning. The temperature data can be transmitted to the control system through the communication module to provide a basis for subsequent temperature control strategies.

[0062] As Figures 1 to 8 shown, a second multi-stage regulation mechanism 7 is further configured on the limit frame 43. The second multi-stage regulation mechanism 7 includes a nut sleeve block 71 slidably installed inside the limit frame 43 and meshed with the threaded rod 44. A U-shaped sleeve shaft 72 is fixedly installed on one side of the nut sleeve block 71 facing the wiring component group 2. A third servo motor 73 is fixedly installed on the side surface of the U-shaped sleeve shaft 72. The output end of the third servo motor 73 passes through the inside of the U-shaped sleeve shaft 72 and is fixedly installed with an electric telescopic rod 74. The electric telescopic rod 74 is integrally movably hinged inside the U-shaped sleeve shaft 72. The output end of the electric telescopic rod 74 is fixedly installed with a fourth servo motor 75 parallel to the third servo motor 73. The output end of the fourth servo motor 75 is fixedly installed with an extension rod 76, and the extension rod 76 is integrally L-shaped.

[0063] Among them, the configured second multi-stage regulation mechanism 7 is mainly used to adjust the orientation of the electric control external expansion module 8.

[0064] As Figures 1 to 8As shown, an electrically controlled outer deployment module 8 is also arranged at the outer protruding end of the extension rod 76. The electrically controlled outer deployment module 8 includes a bidirectional articulated electric telescopic rod 81 fixedly installed at the protruding end of the extension rod 76. L-shaped articulated sleeve plates 82 are movably installed on both sides of the articulated output ends of the bidirectional articulated electric telescopic rod 81. Joint heads 83 are fixedly connected to the protruding ends of the two groups of L-shaped articulated sleeve plates 82. L-shaped extension plates 84 parallel to the L-shaped articulated sleeve plates 82 on the same side are fixedly connected to the outsides of the joint heads 83. The two groups of L-shaped articulated sleeve plates 82 are articulated to the exact bottom of the bidirectional articulated electric telescopic rod 81 through the joint heads 83.

[0065] As Figures 1 to 8 shown, a variable circular ring guide mechanism 9 is also arranged on the outside of the L-shaped extension plate 84. The variable circular ring guide mechanism 9 includes semi-circular ring guides 91 fixedly installed on the outsides of the two groups of L-shaped extension plates 84. Second circular groove tracks 92 are formed on the surfaces of the semi-circular ring guides 91. Tooth blocks 94 are fixedly installed on one side edges of the inner bottoms of the second circular groove tracks 92, and magnetic adsorption coatings 95 are fixedly installed on the other side edges. Limit retaining rings 93 are fixedly installed on the upper side walls of the second circular groove tracks 92 located above the magnetic adsorption coatings 95. Magnetic adsorption positioning coatings 910 are fixedly installed on both end faces of the semi-circular ring guides 91. The semi-circular ring guides 91 on the outsides of the two groups of L-shaped extension plates 84 can be adsorbed and adhered to form a complete circular ring structure through the magnetic adsorption positioning coatings 910.

[0066] As Figures 1 to 8 shown, the variable circular ring guide mechanism 9 also includes a fifth servo motor 97 sleeved in one of the second circular groove tracks 92. A second gear disk 96 is fixedly installed at the output end of the fifth servo motor 97. The second gear disk 96 is integrally clamped at the bottom of the limit retaining ring 93 and adsorbed on the magnetic adsorption coating 95. A plasticizable support rod 98 is fixedly installed at one end of the outer surface of the fifth servo motor 97 away from the fifth servo motor 97. A second infrared temperature control unit 99 is fixedly installed on the outside of the plasticizable support rod 98.

[0067] Among them, the configured second infrared temperature control unit 99 is a more specific detection module different from the first infrared temperature control unit 5. During the actual working process, in the process of monitoring temperature by the traditional fixed-point monitoring mechanism, it is impossible to change the monitoring direction with the first infrared temperature control unit 5 controlled by the circumferential guiding mechanism 4. Therefore, a dynamic detection system is established by the first multi-level regulation mechanism 3 in cooperation with the circumferential guiding mechanism 4. Further, there are many structures on the wiring component group 2, and the temperature of each structure is different in the working state and the fault state. Because of the dense component area, the poor air fluidity forms a heat island effect, while the heat dissipation is faster in the open area. The temperature rise of current-heating type equipment has a strong correlation, and the temperature difference between different parts of a single device is also large, resulting in uneven temperature point distribution. The uneven temperature distribution inside the power distribution cabinet is mainly caused by the material characteristics, contact resistance, operating conditions and heat dissipation conditions differences of different components, and the temperature has divergence, that is, there may still be different heating components in the same abnormal temperature area. Therefore, it is necessary to further detect the specific points.

[0068] In the above background, the cooperation of its second multi-level regulation mechanism 7 and the variable circular guide rail mechanism 9 constitutes a system that can enable the second infrared temperature control unit 99 to conduct further temperature monitoring around the interface wire. Specifically:

[0069] First, during the detection process of the circumferential guiding mechanism 4 driving the first infrared temperature control unit 5, when the temperature of a certain area is found to be abnormal, the second servo motor 42 outside the limit frame 43 can be used to drive the second multi-level regulation mechanism 7 to move in the up and down direction of the limit frame 43 by the rotation of the threaded rod 44 at the output end of the second servo motor 42, so as to approach the first infrared temperature control unit 5 where the temperature abnormality is detected, that is, the moving nut sleeve block 71 reaches the position of the first infrared temperature control unit 5 where the temperature abnormality is detected.

[0070] Then, through the servo driving action at the output end of the third servo motor 73 on the side of the U-shaped sleeve shaft 72, the electric telescopic rod 74 articulated inside is controlled to turn up and down, so that the outer end of the electric telescopic rod 74 can further approach the heat source point, and then with the driving force at the output end of the fourth servo motor 75 outside, the extension rod 76 is controlled to rotate, so that the electric control outer expansion module 8 approaches the heat source point on the premise of not interfering with the electronic component structure.

[0071] Then, through the two articulated electric telescopic ends configured on the bidirectional articulated electric telescopic rod 81, the electric telescopic ends are used to contract inward, tightening the two sets of L-shaped articulated sleeve plates 82 that are articulated. Just like scissors in the prior art, the outer side of the L-shaped extension plate 84 is unfolded outward, opening the two semi-circular guide rails 91. Then, the opened two semi-circular guide rails 91 are leaned against the position of the wire joint to be detected. And the bidirectional articulated electric telescopic rod 81 is used to expand outward again, making the L-shaped extension plate 84 approach inward, forming the two semi-circular guide rails 91 into a complete circular ring structure, enabling the second infrared temperature control unit 99 to rotate 360 degrees on this circular ring structure to conduct covering monitoring on the interface end.

[0072] Among them, when the second infrared temperature control unit 99 is working, one end of its circumferential guiding mechanism 4 is in a disconnected state, that is, the electromagnet unit 381 is in a closed state. And the so-called bidirectional articulated electric telescopic rod 81 is two electric telescopic ends that are both articulated through activities, used to control the expansion and retraction of the L-shaped articulated sleeve plate 82, simulating the expansion of scissors.

[0073] Because it is necessary to contact the specific situation of the interface end, it is necessary to construct a circular ring structure that can be sleeved outside the wire for the second infrared temperature control unit 99 to move. Therefore, two semi-circular guide rails 91 that can form a complete circular ring are provided. A magnetic adsorption positioning coating 910 is provided on the side end surface of each semi-circular guide rail 91, enabling the two semi-circular rings to fit more closely when they are joined. Inside the semi-circular guide rail 91, a structure that can clamp the second gear disk 96 is formed by a limit retaining ring 93 and a magnetic adsorption coating 95, so that the second gear disk 96 will not fall out of the second circular ring groove track 92 in any state. The fifth servo motor 97 configured on the outside of the second gear disk 96 is also clamped inside the second circular ring groove track 92 as a whole. Driven by the output end of the fifth servo motor 97, the second gear disk 96 bites the tooth block 94 at the bottom of the second circular ring groove track 92 to move.

[0074] As Figures 1 to 8 shown, a flow guide cover 388 is fixedly installed at the position where the bottom of the runway-shaped housing 31 is located on one side and reserved for the side end of the opening 35. The bottom of the flow guide cover 388 is connected to an air delivery hose 10 in a communicating manner. Air guide pipes 85 are fixedly installed on the outer side edges of the L-shaped extension plate 84. A number of air outlet openings 86 are provided on the surface of the air guide pipes 85. The side of the air delivery hose 10 away from the flow guide cover 388 is connected to the two air guide pipes 85 in a communicating manner through a Y-shaped pipe.

[0075] Among them, the configured fairing 388 is to further utilize the wind generated at the position of the first air guiding module 36. Because when the subsequent second infrared temperature control unit 99 detects the components in a single position area, the stability of the overall environment inside the cabinet will affect the monitoring of a certain point. Therefore, the fairing 388 is used to appropriately introduce a part of the air flow into the air delivery hose 10, and then through the air delivery hose 10 to the air guiding pipe 85 on the L-shaped extension plate 84, and finally discharged through the air outlet opening 86 on the air guiding pipe 85, so that the air flow can be further introduced outside the detection area of the second infrared temperature control unit 99, further reducing the interference of the outside temperature and improving the accuracy of the overall temperature feedback end.
