Description

Technical Field

[0001] This invention relates to the field of junction boxes, and in particular to an electrical junction box that facilitates temperature control. Background Technology

[0002] Electrical junction boxes are devices used to install and connect electrical equipment. They are usually made of metal or plastic and are widely used in industrial, commercial and residential buildings for controlling and distributing power and signals. As a key component in the operation and maintenance of electrical equipment, the performance and safety of electrical junction boxes are of paramount importance.

[0003] Traditional electrical junction boxes typically only have basic protection and wiring functions. However, they lack effective temperature control measures when faced with high temperatures or abnormally high temperatures, which may lead to damage to electrical components inside the junction box or even cause safety accidents such as fires.

[0004] To address this issue, some electrical junction boxes with temperature control functions have emerged on the market. However, these products often suffer from poor temperature control performance. For example, some products achieve temperature control by adding additional cooling equipment, which not only increases the complexity and cost of the equipment but may also reduce overall efficiency due to additional energy consumption. Furthermore, the temperature control system of some products has a slow response speed and cannot respond to temperature anomalies in a timely and effective manner, thus failing to fully guarantee the safety of electrical components. Therefore, we propose an electrical junction box that facilitates temperature control. Summary of the Invention

[0005] The purpose of this invention is to provide a novel electrical junction box that has efficient, reliable, and easy-to-maintain temperature control functions to adapt to various complex working environments and ensure the stable operation of electrical equipment, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: an electrical junction box for easy temperature control, comprising a box body and a box cover, wherein the box cover is respectively provided with an air inlet and an air outlet, and an air inlet fan and an air outlet fan are respectively provided at the air inlet and the air outlet, and further comprising:

[0007] The air duct mechanism is installed inside the housing and distributed at the wiring positions on the inner wall of the housing;

[0008] The air control unit is installed inside the box cover and connected to the air duct mechanism. In the initial state, the air intake fan draws in air normally, and the air exhaust fan draws air directly from the wiring position and exhausts it outside using the air duct mechanism.

[0009] A temperature-sensing control module is installed inside the enclosure to set the operation of the air control unit according to the temperature level, switching the intake fan and the exhaust fan to simultaneously exhaust air from the air duct mechanism. An electrical control unit is also installed inside the enclosure and is connected to the enclosure cover. When the air control unit is activated, the electrical control unit is driven to open the enclosure cover simultaneously.

[0010] With the above design, during normal use, the cover is closed, the intake fan supplies air into the box, and the exhaust fan draws air directly from the heat-generating location inside the box using the air duct mechanism, thereby minimizing the dissipation of excessive heat inside the box and ensuring effective heat dissipation in conjunction with airflow circulation.

[0011] In addition, when the temperature inside the chamber rises significantly, the working mode of the exhaust fan can be switched using the air control unit. The mode will switch from drawing air out of the chamber to filling the chamber with air. When combined with the air duct mechanism and the chamber cover is open, air can be directly injected into the heat-generating area inside the chamber from the air duct mechanism, thereby directly and quickly blowing the generated heat out of the chamber to the opening, so as to achieve the purpose of rapid cooling.

[0012] In some embodiments, the air duct mechanism includes two manifolds, the air control unit is connected to the adjacent manifold, and a plurality of branch pipes are fixed at intervals between the two manifolds, and a plurality of nozzles are provided through the branch pipes at positions directly opposite the door.

[0013] The design of multiple diversion pipes and nozzles allows for direct air cooling from the heat-generating locations of electrical components inside the enclosure, effectively preventing heat diffusion and accumulation within the enclosure. This avoids the problem of heat accumulation at the corners of traditional air-cooled enclosures, ensuring efficient heat dissipation.

[0014] In some embodiments, the diverter pipe is U-shaped, and the collector pipe is located at the box opening.

[0015] The U-shaped design of the diversion pipe makes it easier to disassemble and assemble the entire air duct mechanism inside the box. That is, the overall air outlet is located inside the box, but the part used to connect the air control unit can be exposed at the box opening, which is convenient for disassembly and use.

[0016] In some embodiments, the temperature control module includes a controller installed inside the enclosure, and a temperature sensor is also installed inside the enclosure. The temperature sensor is connected to the controller, and when the temperature exceeds the monitoring threshold, the controller controls the electrical control unit and the air control unit to operate.

[0017] Temperature sensors are used to monitor the temperature inside the chamber in real time, while controllers are used to control the switching of the exhaust fan and air control unit according to the real-time temperature inside the chamber, ensuring effective temperature sensing and control.

[0018] In some embodiments, the air control unit includes a diversion box installed inside the box cover, the diversion box covering both the outside of the air inlet and the air outlet, and a partition is provided inside the diversion box at a position between the air inlet and the air outlet to divide the interior of the diversion box into an air inlet chamber and an air outlet chamber.

[0019] The manifold is connected to the outlet chamber via a conduit, and the surface of the distributor box is provided with an inlet hole that communicates with the inlet chamber.

[0020] Furthermore, a flow control unit is installed on the distribution box. When the temperature exceeds the preset limit in real time, the flow control unit controls the intake fan and the exhaust fan to supply air into the manifold simultaneously.

[0021] In practical use, the air intake fan blows air directly into the chamber. However, when the temperature inside the chamber rises significantly, the air control unit is controlled by the controller to switch the direction of the air intake fan, so that the air intake fan and the exhaust fan can simultaneously blow the heated air directly from inside the chamber to the outside of the chamber, ensuring efficient heat dissipation.

[0022] In some embodiments, the flow control unit includes a cover plate that is slidably disposed on the flow divider box and seamlessly abuts against the surface of the flow divider box;

[0023] Furthermore, the cover plate is provided with a guide hole that is misaligned with the air inlet. In the initial state, the guide hole is connected to and directly opposite the air inlet.

[0024] An air duct is provided on the partition, and a drive component connected to the cover plate is provided on the cover plate. When the controller issues a control command, the drive component drives the cover plate to move and block the air inlet.

[0025] Furthermore, the controller immediately reverses the air outlet fan.

[0026] The above design allows for switching between the working modes of the intake and exhaust fans simply by moving the cover plate. Under normal operating conditions, the airflow from the intake fan blows directly into the housing through the guide hole. During switching, the cover plate moves to misalign the guide hole with the intake hole, and the guide hole is opened, connecting the intake and exhaust chambers. At this time, in conjunction with the reverse rotation of the exhaust fan, the intake and exhaust chambers simultaneously fill the air duct mechanism with air for cooling.

[0027] In some embodiments, sliding grooves are provided on both the upper and lower side walls of the distribution box, and sliding strips are provided at both the upper and lower ends of the cover plate. The sliding strips are fastened in the sliding grooves so that the cover plate is slidably fastened to the distribution box.

[0028] The design of the slide and the slide bar ensures that the cover plate is slidably connected to the distribution box and does not detach from the distribution box, thus ensuring ease of use.

[0029] In some embodiments, the diversion box is further provided with a through hole, and a sealing plate is fixed inside the cover plate. The sealing plate passes through the through hole, and in the initial state, the sealing plate and the partition are seamlessly connected.

[0030] By designing a sealing plate to separate the air inlet and outlet chambers, the exhaust fan can ensure stable and effective air extraction directly from the heat generation location through the air duct mechanism when exhausting air.

[0031] In some embodiments, the drive unit includes an electric push rod mounted on the cover. The electric push rod is located on either side of the splitter box. In the initial state, the slide bar is located in the slide groove at the end away from the electric push rod. At this time, the electric push rod is in an extended state, and the air inlet and the guide hole are connected.

[0032] By setting up an electric actuator, the movement and state switching of the cover plate can be directly completed by the electric actuator when the controller is in control.

[0033] In some embodiments, the air duct mechanism, the air control unit, and the temperature control module are all detachably installed on the housing and the housing cover, respectively.

[0034] In this way, the above design facilitates the disassembly and assembly of each device during use, which not only makes the operation and maintenance of each component easier, but also allows each component to be easily reused.

[0035] This invention has at least the following beneficial effects:

[0036] 1. High-efficiency temperature control: Through precise temperature monitoring and a fast-response air control unit, this junction box can take immediate action when the temperature rises abnormally, effectively reducing the temperature inside the box and protecting electrical components from high-temperature damage, thereby improving the reliability and safety of the equipment.

[0037] 2. Intelligent Automation: The introduction of the temperature sensing control module enables the junction box to automatically adjust the working status of the air control unit according to the real-time temperature, realizing an intelligent and automated temperature control process, reducing the need for manual intervention and improving work efficiency.

[0038] 3. Structural Optimization: The ductwork design employs a combination of manifolds and distributors, along with a U-shaped distributor and nozzles, ensuring uniform airflow distribution and efficient circulation, further enhancing temperature control. Simultaneously, the distributor box design of the air control unit effectively isolates and switches between intake and exhaust air, strengthening the system's stability and controllability.

[0039] 4. Easy to maintain: The air duct mechanism, air control unit, and temperature control module of this junction box are all designed to be detachable, facilitating daily inspection and maintenance by users, reducing maintenance difficulty and cost, and extending the service life of the equipment.

[0040] In summary, the temperature-controlled electrical junction box of this application has achieved significant beneficial effects in terms of improving temperature control efficiency, realizing intelligent management, optimizing structural design, facilitating maintenance, and energy conservation and environmental protection, providing a strong guarantee for the stable operation of electrical equipment.

Detailed Implementation

[0048] 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 embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0049] This application provides a technical solution:

[0050] See appendix Figure 1 , Figure 6 As shown, an electrical junction box that facilitates temperature control mainly includes a box body 1 and a box cover 2. The box cover 2 is provided with an air inlet 3 and an air outlet 4, and an air intake fan 5 and an air outlet fan 6 are respectively provided at the air inlet 3 and the air outlet 4 to ensure smooth airflow inside and outside the box and provide circulating cooling airflow.

[0051] See appendix Figures 2-4 As shown, an air duct mechanism 7 is arranged at the wiring position on the inner wall of the housing 1, closely fitting the wiring position on the inner wall. This is designed to achieve efficient heat conduction and dissipation. The air duct mechanism 7 is based on two manifolds 71, which are closely connected to the air control unit 8, forming a circulation path for the airflow. Between the two manifolds 71, multiple U-shaped branch pipes 72 are fixed and connected. The manifolds 71 ​​are located at the housing opening, while the branch pipes 72 are distributed from the wiring position on the inner wall of the housing 1 using a U-shaped design, making the air duct arrangement more convenient. In addition, multiple nozzles 73 are installed on these branch pipes 72 facing the housing door. Through this design, air can be directly drawn from the heat-generating position inside the housing 1. When heat is generated and begins to diffuse in the air, the heated air can be drawn out in time, maximizing the rapid dissipation of heat generated by electrical components and effectively enhancing the heat dissipation effect.

[0052] See appendix Figure 3 As shown, the temperature control module 9, as the intelligent core of the junction box, is built into the box 1. It can accurately regulate the action of the air control unit 8 according to the temperature change. This module consists of a controller 91 and a temperature sensor 92. When the temperature exceeds the preset monitoring threshold without affecting the performance of electrical components, the controller 91 will respond quickly and drive the electric control unit 10. The conventional electric window opener in the prior art is sufficient and does not involve the core part of this solution, so it is not described in detail. It works in conjunction with the air control unit 8 to ensure that the temperature inside the box is always within a safe range.

[0053] See appendix Figures 5-6 As shown, the air control unit 8 includes a diversion box 81 installed inside the box cover 2. The diversion box 81 covers the outside of the air inlet 3 and the air outlet 4. A partition 82 is fixedly installed inside the diversion box 81 at the position between the air inlet 3 and the air outlet 4 to divide the inside of the diversion box 81 into an air inlet chamber 83 and an air outlet chamber 84.

[0054] The manifold 71 is connected to the outlet chamber 84 via a conduit, and the surface of the distributor box 81 is provided with an inlet hole 85 that communicates with the inlet chamber 83.

[0055] A flow control unit 86 is also provided on the distribution box 81. When the temperature exceeds the preset limit in real time, the flow control unit 86 controls the intake fan 5 and the exhaust fan 6 to supply air into the collection pipe 71 at the same time.

[0056] See appendix Figures 5-6 As shown, specifically, the flow control unit 86 includes a cover plate 861 that is slidably disposed on the flow divider box 81. The cover plate 861 is seamlessly abutted against the surface of the flow divider box 81 to ensure stable airflow. A guide hole 862 that is misaligned with the air inlet 85 is opened on the cover plate 861. In the initial state, the guide hole 862 is directly connected to the air inlet 85 to achieve smooth airflow.

[0057] An air guide hole 863 is provided on the partition plate 82, and a drive component 864 connected to the cover plate 861 is provided on the cover 2. The drive component 864 is an electric push rod 865. The electric push rod 865 is installed on the cover 2, and its output end is connected to the cover plate 861. In the initial state, the slide bar 88 is located in the slide groove 87 at the end away from the electric push rod 865. At this time, the electric push rod 865 is in the extended state, and the air inlet 85 is connected to the guide hole 862. When the temperature rises abnormally, when the controller 91 issues a control command, the electric push rod 865 pushes the cover plate 861 to move and block the air inlet 85.

[0058] Simultaneously, controller 91 controls the exhaust fan 6 to reverse. In this state, both the intake fan 5 and the exhaust fan 6 blow air into the housing 1. At this time, the gas will be introduced into the air duct mechanism 7 through the diversion box 81. At this time, the electrical control unit 10 of the housing cover 2 directly controls the opening and closing of the housing cover 2. It should be emphasized that the nozzle 73 of the air duct mechanism 7 is directly facing the housing door. In this way, when the nozzle 73 sprays air quickly, it can quickly blow the high-temperature airflow inside the housing 1 out of the housing 1, thereby achieving the purpose of rapid cooling and temperature control. The reason why this method is not used in the normal initial state is that the heat dissipation hole of the housing cover 2 is not likely to be very large. This causes the airflow of the nozzle 73 to be unable to be directly and completely discharged to the outside of the housing 1. This will cause the airflow inside the housing 1 to be chaotic, and the high-temperature airflow will still accumulate to a certain extent inside the housing 1.

[0059] To ensure the stable sliding of the cover plate 861, grooves 87 are provided on the upper and lower side walls of the diversion box 81, and slide bars 88 are provided at the upper and lower ends of the cover plate 861. The slide bars 88 are L-shaped and fixed at the cover plate 861. The L-shaped ends of the slide bars 88 extend and are fastened in the grooves 87. The slide bars 88 are fastened in the grooves 87, so that the cover plate 861 can slide smoothly on the diversion box 81.

[0060] In addition, a through hole 89 is provided on the diversion box 81, and a sealing plate 810 is fixed inside the cover plate 861. The sealing plate 810 passes through the through hole 89 and fits seamlessly with the partition plate 82. The thickness of the through hole 89 is greater than the thickness of the sealing plate 810, so that the sealing plate 810 can move within the through hole 89. The sealing plate 810 completely covers the air guide hole 863 on the partition plate 82, while the through hole 89 is always covered by the cover plate 861. Therefore, the through hole 89 is always blocked from air, thereby realizing the connection and buoyancy between the air inlet chamber 83 and the air outlet chamber 84, further enhancing the stability of the airflow.

[0061] Regarding the above features, during normal use, the intake fan 5 supplies airflow into the housing 1, while the exhaust fan 6 draws in high-temperature airflow from the housing 1 to dissipate heat and cool down. However, the drawback of this method is obvious: heat accumulation is still inevitable during continuous use, so the inside of the housing 1 will continue to heat up.

[0062] In this design, when the temperature sensor 92 detects that the temperature inside the enclosure 1 is too high, the controller 91 reacts immediately and sets the electric push rod 865 to move to completely block the air inlet chamber 83. The air inlet chamber 83 and the air outlet chamber 84 are connected through the air guide hole 863. In this case, the air intake fan 5 continues to supply air, and the gas is blown to the air outlet chamber 84 through the partition 82. At the same time, the air outlet fan 6 reverses, and the enclosure cover 2 is quickly opened to switch to emergency mode. In this way, air is supplied to the air duct mechanism 7 from two points at the same time. The nozzle 73 can spray the heat-generating electrical components inside the enclosure 1 directly with the maximum airflow volume and quickly discharge the high-temperature gas inside the enclosure 1 to the enclosure opening for rapid temperature control of the junction box.

[0063] After the temperature control is completed, all the above states are reset, maintaining the normal closed state of the chamber 1 and the cover 2.

[0064] It should be noted that the air duct mechanism 7, the air control unit 8, and the temperature control module 9 are all detachably installed on the housing 1 and the cover 2 respectively. This design not only facilitates the user's daily inspection and maintenance, but also provides great convenience for future upgrades and modifications.

[0065] In conclusion, this electrical junction box, with its ingenious design, comprehensive functions, and intelligent control methods, provides users with an efficient, safe, and reliable electrical wiring environment.

[0066] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention.
