Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and in particular to a comprehensive distribution box with heat dissipation and airflow control functions. Background Technology

[0002] A distribution box, also known as a distribution cabinet, is a device that assembles and protects switching equipment, protective electrical appliances, and auxiliary equipment. The electrical equipment inside the distribution box generates heat during operation. Existing integrated distribution boxes typically use sensors to detect the temperature at designated locations inside, thereby controlling the start and speed of fans to dissipate heat. However, electrical equipment is often concentrated in the distribution box, resulting in poor airflow around the equipment. The airflow struggles to remove heat from the surrounding area, and the fans cannot effectively expel heat from the distribution box, leading to accelerated aging of the equipment and increased risk of failure. Therefore, a comprehensive distribution box with heat dissipation and airflow control functions is designed. Summary of the Invention

[0037] 1. This invention, by setting up a fan and an air restrictor, allows the fan blades to rotate and cause the gas in the enclosure to flow towards the fan when the fan is started. As the gas passes through the fan, part of the airflow flows through the air restrictor to the ventilation holes in the enclosure and is discharged outside the device, while the other part flows back into the enclosure through the gap between the fan and the air restrictor under the diffusion effect of air pressure, thus forming a circulation of airflow in the enclosure. This allows the airflow in the enclosure to carry away the heat generated by the electrical equipment during operation, effectively improving the heat dissipation effect of the electrical equipment in the enclosure.

[0038] 2. By incorporating air guide vanes, the heat from the electrical equipment is transferred to the mounting frame via contact propagation and then to the air guide vanes through the heat dissipation beam. This raises the air temperature at the air guide vanes, causing the air to flow upwards along the vanes and compress the room-temperature air inside the heat dissipation beam. The room-temperature air then flows downwards to fill the airflow gap at the air guide vanes. The hot airflow ultimately transfers heat to the housing and heat dissipation fins, where it is dissipated. The hot airflow then transforms into room-temperature airflow, flowing downwards, while the room-temperature air absorbs the heat from the air guide vanes and flows upwards, creating a circulation of air inside the heat dissipation beam. This further releases heat from the electrical equipment and extends its service life.

[0039] 3. By incorporating a pneumatic plug, this invention utilizes helium as the primary force to drive the sliding stepped cylinder downwards when the air pressure decreases on rainy days. This downward movement of the sliding stepped cylinder causes the fan to move synchronously, thereby reducing the gap between the fan and the air restrictor. This allows outside air to quickly exchange heat upon entering the enclosure and be guided out by the fan, maintaining a low temperature inside the enclosure that does not damage the electrical equipment. After absorbing heat, the airflow around the electrical equipment will move towards the airflow at the fan due to the pressure difference inside the enclosure, thus accelerating the cooling speed of the electrical equipment and improving its service life.

Detailed Implementation

[0051] The technical solution of the present invention will be further described below with reference to the accompanying drawings. Example

[0052] A type of integrated distribution box with heat dissipation and airflow control functions, such as Figures 1-10 As shown, the device includes a housing 1, a door 2, and a first arc-shaped air guide plate 201. The housing 1 is used to install electrical equipment. The door 2 is hinged to one side of the housing 1 and has several first ventilation slots for ventilation. The first arc-shaped air guide plate 201 is welded to the first ventilation slots of the door 2, and there are several of them. The first arc-shaped air guide plate 201 is used to adjust the airflow direction. The device also includes a ventilation adjustment mechanism 3, a heat dissipation installation mechanism 4, and an air inlet adjustment mechanism 5. The ventilation adjustment mechanism 3 is located at the bottom of the housing 1 and is used to adjust the airflow inside the housing 1 so that the airflow inside the housing 1 can adjust its direction according to changes in the surrounding environment. The heat dissipation installation mechanism 4 is located on one side of the housing 1 and is made of metal. It is used to install electrical equipment and remove the heat generated by the electrical equipment through airflow. The air inlet adjustment mechanism 5 is located on one side of the door 2 and is used to adjust the airflow rate entering the housing 1 according to the surrounding environment.

[0053] like Figures 2-4 As shown, the ventilation adjustment mechanism 3 includes a support cylinder 301, a sliding step cylinder 302, and a fan 303. The support cylinder 301 is rectangularly distributed and fixed to the bottom of the inner side of the housing 1. The sliding step cylinder 302 is slidably connected to the inside of the support cylinder 301. The sliding step cylinder 302 corresponds one-to-one with the support cylinder 301. The fan 303 is installed on the top of the sliding step cylinder 302. Several ventilation holes 101 are opened at the bottom of the housing 1. The ventilation holes 101 are located directly below the fan 303.

[0054] like Figures 3-4As shown, the ventilation regulating mechanism 3 also includes a limited air duct 304 and a heat-conducting plug 305. The limited air duct 304 is fixed to the bottom of the inner part of the box 1. The air duct 304 is located between the fan 303 and the box 1. The heat-conducting plug 305 is fixed to the bottom of the box 1. The top of the heat-conducting plug 305 penetrates the bottom of the box 1 and is located inside the support cylinder 301. The heat-conducting plug 305 is made of pure copper. The bottom of the heat-conducting plug 305 is provided with multiple annular protrusions to accelerate the transfer of heat.

[0055] like Figure 3 As shown, the ventilation regulating mechanism 3 also includes a pneumatic plug 306. A cylindrical groove is provided inside the sliding stepped cylinder 302. The top of the cylindrical groove is connected to the inside of the housing 1. The pneumatic plug 306 is slidably connected inside the sliding stepped cylinder 302 and is slidably connected to the support cylinder 301. The support cylinder 301, the heat-conducting plug 305 and the pneumatic plug 306 form a first cavity. The first cavity is filled with carbon dioxide. Carbon dioxide is more likely to expand due to temperature changes. The sliding stepped cylinder 302 and the pneumatic plug 306 form a second cavity. The second cavity is filled with helium. Helium is more likely to expand due to pressure changes at room temperature.

[0056] like Figure 2 and Figures 5-7 As shown, the heat dissipation mechanism 4 includes a heat dissipation beam 401 and an air guide 402. The heat dissipation beam 401 is symmetrically distributed and fixed to one side of the housing 1. The air guide 402 is vertically linearly distributed and fixed inside the heat dissipation beam 401. The air guide 402 consists of an inclined plate and several semi-circular arc plates. The inclined plate is used to guide the airflow direction, so that the hot airflow flows towards the top of the inclined plate. The semi-circular arc plates are used to connect the top and bottom of the inclined plate, and together with the inclined plate, the hot airflow can flow quickly in the vertical direction.

[0057] like Figures 5-6 As shown, the heat dissipation installation mechanism 4 also includes a U-shaped beam 403 and heat sinks 404. The U-shaped beam 403 is welded to both sides of the heat dissipation beam 401, and the heat sinks 404 are linearly distributed and fixed to one side of the inside of the U-shaped beam 403.

[0058] like Figures 5-6 As shown, the heat dissipation installation mechanism 4 also includes a mounting bracket 405. Several vertical positioning slots 4031 are provided on the U-shaped beam 403. The mounting bracket 405 is fixedly installed on the vertical positioning slots 4031 by bolts for installing electrical equipment.

[0059] like Figure 2 and Figures 8-10As shown, the air intake adjustment mechanism 5 includes a sliding ventilation plate 501 and a second arc-shaped air guide plate 5011. The sliding ventilation plate 501 is slidably connected to one side of the box door 2. A second ventilation slot is opened on one side of the sliding ventilation plate 501, which corresponds to and communicates with the first ventilation slot of the box door 2. The second arc-shaped air guide plate 5011 is installed at the second ventilation slot of the sliding ventilation plate 501 to guide the flow direction of the airflow.

[0060] like Figures 8-9 As shown, the air intake adjustment mechanism 5 also includes a sealing frame 502, an air pressure plate 503, a connecting rod 504, a guide frame 505, and a sliding rod 506. The sealing frame 502 is located on one side of the door 2. The air pressure plate 503 is slidably connected to the inside of the sealing frame 502. The sealing frame 502 and the air pressure plate 503 form a third cavity, which is filled with air. The connecting rod 504 is symmetrically distributed and hinged to the air pressure plate 503. The guide frame 505 is symmetrically distributed and fixed to one side of the door 2. The sliding rod 506 is slidably connected to one side of the guide frame 505. The sliding rod 506 is hinged to the connecting rod 504, and the bottom of the sliding rod 506 is fixed to the sliding ventilation plate 501.

[0061] Existing distribution boxes use fans to guide airflow from inside the box to the outside, thus facilitating airflow and allowing the airflow to absorb heat generated by the electrical equipment during operation. This heat is then expelled from the distribution box by the fan, achieving heat dissipation for the electrical equipment. However, in practical applications, the electrical equipment is often densely distributed within the distribution box, making airflow around the equipment difficult and hindering the dissipation of heat. To address this, this device incorporates a vertically movable fan 303, which generates heat at different heights within the box 1. The circulating airflow in the same state passes through the vicinity of the electrical equipment at different intensities, absorbing and carrying away the heat generated by the electrical equipment, ensuring the normal operation of the electrical equipment. In addition, this equipment also sets up heat dissipation beams 401 and air guides 402, so that the heat of the electrical equipment can be efficiently and quickly transferred to the air guides 402 through contact propagation, thereby increasing the propagation area when the heat is propagated to the air, so that the heat is transferred to the air. The air in the heat dissipation beams 401 forms a spontaneous thermal cycle through the change of air density, so that the heat of the electrical equipment can be dissipated more efficiently, further ensuring the normal operation of the electrical equipment.

[0062] In the initial state, the first ventilation slot of the door 2 is connected to the second ventilation slot of the sliding ventilation vane 501, and the second ventilation slot of the sliding ventilation vane 501 is located in the middle of the first ventilation slot of the door 2. In addition, the fan 303 is always on, keeping the airflow inside the box 1 flowing. The support cylinder 301, the heat-conducting plug 305, and the pneumatic plug 306 form the first cavity. The carbon dioxide in the first cavity supports the pneumatic plug 306 through its own pressure, thereby restricting the position of the pneumatic plug 306 within the support cylinder 301. The sliding stepped cylinder 302 and the pneumatic plug 306 form the second cavity. The helium in the second cavity supports the sliding stepped cylinder 302 through its own pressure, thereby restricting the position of the sliding stepped cylinder 302 on the pneumatic plug 306. The carbon dioxide in the first cavity... The combined action of carbon dioxide and helium in the second chamber causes the sliding stepped cylinder 302 to support the fan 303. A gap is left between the fan 303 and the top of the air restrictor 304. The sealing frame 502 and the pressure plate 503 form a third chamber. The air in the third chamber restricts the position of the pressure plate 503 within the sealing frame 502 by its own air pressure. When the fan 303 is working, the fan blades of the fan 303 rotate and draw in the surrounding air, causing the air to be drawn downward by the fan blades and discharged into the housing 1 through the ventilation hole 101. At this time, the air pressure at the fan 303 decreases, causing the fan 303 to drive the air in the housing 1 to flow towards the fan 303, forming an airflow. In addition, the downward flow of air drawn in by the fan 303 causes the air to be locally compressed, resulting in an increase in the air pressure of the airflow. The airflow increases, and through pressure diffusion, it flows into the gap between the fan 303 and the air restrictor 304, then flows back into the housing 1. The airflow then flows upwards, passing around the electrical equipment and absorbing the heat generated during operation, thus lowering the temperature of the equipment and preventing it from overheating and automatically shutting off, ensuring its normal operation. The airflow then continues upwards to the top of the housing 1, where it flows downwards under the restriction of the top, returning to the fan 303 and forming an airflow circulation within the housing 1. This effectively absorbs the heat generated during the operation of the electrical equipment. Furthermore, as the airflow is guided out of the housing 1 by the fan 303, the airflow movement causes the housing 1... The air pressure inside the box decreases, and due to the pressure difference with the airflow inside the box 1, the outside air flows upward under the guidance of the first arc-shaped air guide plate 201 and enters the first ventilation slot of the box door 2. Subsequently, the outside air continues to flow into the second ventilation slot of the airflow exiting the sliding ventilation fin 501, and then flows downward along the second arc-shaped air guide plate 5011 into the box 1. It is worth noting that because the outside airflow enters the box 1 through negative pressure, the airflow intensity when the outside airflow enters the box 1 is greater than the airflow intensity of the upward flow inside the box 1. This prevents the airflow inside the box 1 from flowing out of the box 1 through the first ventilation slot of the box door 2 and the second ventilation slot of the sliding ventilation fin 501. Furthermore, when the electrical equipment is operating, because the heat dissipation mechanism 4 is made of metal...Metal materials possess high heat transfer efficiency and low heat capacity, and heat only actively diffuses from high-heat areas to low-heat areas. This allows the heat generated by electrical equipment to be rapidly transferred to the heat dissipation beam 401 via contact propagation. After absorbing heat, the heat dissipation beam 401 quickly transfers it to the air guide vanes 402 via heat contact diffusion. The array of air guide vanes 402 increases the heat dissipation area of ​​the air guide vanes 402 and the air inside the heat dissipation beam 401, thereby transferring the heat from the heat dissipation beam 401 and the air guide vanes 402 to the surrounding air. After absorbing heat, the air density decreases, generating buoyancy that causes it to move upwards, forming a hot airflow. This hot airflow is guided by the inclined plates of the air guide vanes 402. The hot air flows upward and passes through the semi-circular plate of the air guide 402, causing the hot air to accumulate at the top of the heat dissipation beam 401. The upward flow of the hot air causes a decrease in air pressure at the bottom of the heat dissipation beam 401. On the side of the heat dissipation beam 401 not connected to the air guide 402, the air is at room temperature. This air flows downward under the pressure difference within the heat dissipation beam 401, forming a room temperature airflow. This room temperature airflow flows downward to the bottom of the heat dissipation beam 401 and then flows upward along the side of the heat dissipation beam 401 connected to the air guide 402, filling the low-pressure area at the bottom of the heat dissipation beam 401. Simultaneously, as the hot air continues to accumulate inside the heat dissipation beam 401, the hot air will... The airflow on the side of the heat dissipation beam 401 without the connected air guide 402 flows downwards. On one hand, it's worth noting that since the airflow temperature inside the housing 1 is based on the temperature of the outside airflow, the outside airflow absorbs heat from the electrical equipment upon entering the housing 1. Therefore, the temperature of the outside airflow is always lower than the temperature of the airflow inside the housing 1. This allows the hot airflow to transfer heat to the housing 1 via the heat dissipation beam 401, and the housing 1 releases heat to the outside. On the other hand, the heat at the heat dissipation beam 401 is transferred to the heat sink 404 via the U-shaped beam 403. As the airflow inside the housing 1 passes over the heat sink 404, it absorbs heat through the surface of the heat sink 404, thus dissipating heat. As the hot airflow inside the heat dissipation beam 401 descends, its temperature continuously decreases until it reaches ambient temperature. This ambient temperature airflow flows downwards along the side of the heat dissipation beam 401 not connected to the air guide 402. Upon reaching the bottom of the heat dissipation beam 401, this airflow flows upwards along the side connected to the air guide 402, reabsorbing heat from the air guide 402 and becoming hot air again. This achieves airflow circulation within the heat dissipation beam 401, allowing the airflow to quickly remove heat generated by the electrical equipment. This ensures the smooth dissipation of heat around the electrical equipment, preventing heat buildup that could lead to overheating and circuit breakage, thus interfering with the normal operation of the electrical equipment.

[0063] When the ambient temperature is high, since the airflow inside enclosure 1 originates from the outside airflow, its temperature is based on the outside airflow temperature. Therefore, the airflow temperature inside enclosure 1 gradually increases as it absorbs heat from the electrical equipment, leading to decreased efficiency in heat absorption. This causes heat to accumulate more easily around the electrical equipment during operation, resulting in faster aging and even automatic power-off. To address this, it is necessary to reduce the time the airflow stays around the electrical equipment inside enclosure 1 to prevent overheating, accelerated aging, and power-off. The ambient temperature is controlled by the heat-conducting plug 305. The gas is transferred to the first cavity, which consists of the support cylinder 301, the heat-conducting plug 305, and the pneumatic plug 306. Notably, the sliding stepped cylinder 302 and the pneumatic plug 306 form the second cavity. Compared to the helium in the second cavity, the carbon dioxide in the first cavity expands more easily due to temperature changes. This carbon dioxide acts as the driving force, increasing the pressure of the heated carbon dioxide in the first cavity. This pressure then pushes the pneumatic plug 306 upwards. The upward movement of the pneumatic plug 306, through the helium, drives the sliding stepped cylinder 302 upwards, which in turn drives the fan 303 upwards. This increases the gap between the fan 303 and the air-limiting cylinder 304, allowing the fan to... When air is drawn downwards, more air passes through the gap between fan 303 and air restrictor 304 back into housing 1, thereby increasing the intensity of the circulating airflow within housing 1. This causes the airflow within housing 1 to absorb heat around the electrical equipment and remain there for a shorter time, thus accelerating the removal of heat from the electrical equipment within housing 1 and reducing the interference caused by the increased airflow temperature within housing 1 on the normal operation of the electrical equipment. Furthermore, the outside air, which is warmer, will be transferred through heat transfer from door 2 to the third cavity formed by sealing frame 502 and pressure plate 503. It is worth noting that initially, pressure plate 503 is located in the middle of sealing frame 502, within the third cavity. The air absorbs heat and expands, increasing the air pressure in the third chamber. This causes the air in the third chamber to push the pressure plate 503 horizontally. The movement of the pressure plate 503, via the connecting rod 504, drives the slide rod 506 to slide upward along the guide frame 505. This causes the slide rod 506 to move the sliding ventilation plate 501 upward, thus fully connecting the second ventilation slot of the sliding ventilation plate 501 with the first ventilation slot of the door 2. This accelerates the entry of outside air into the housing 1 and speeds up the air exchange rate within the housing 1, allowing hot air to flow out of the housing 1 quickly. This further reduces the interference of the increased air temperature within the housing 1 on the heat dissipation of electrical equipment and improves the heat dissipation efficiency of the electrical equipment.

[0064] When the external environment is rainy, the humid air reduces the heat transfer speed of the airflow inside the enclosure 1, thereby reducing the heat dissipation efficiency of the electrical equipment inside the enclosure 1. Furthermore, the high water vapor content lowers the air pressure, and water vapor evaporation leads to a decrease in the ambient temperature. The support cylinder 301, heat-conducting plug 305, and pneumatic plug 306 form the first cavity, while the sliding stepped cylinder 302 and pneumatic plug 306 form the second cavity. Under normal temperature conditions, the water vapor content in the gas significantly interferes with the distribution of carbon dioxide within a given space. This means that the impact of water vapor content on carbon dioxide pressure is significantly greater than the impact of temperature changes on carbon dioxide pressure, and carbon dioxide expands slowly due to its lower pressure expansion rate. Due to the high pressure expansion rate of helium, the helium in the second chamber acts as the primary force. Since the helium pressure in the second chamber is greater than the airflow in chamber 1, the pneumatic plug 306 is positioned by the carbon dioxide in the first chamber. Initially, the top of the pneumatic plug 306 is located in the middle of the cylindrical groove of the sliding stepped cylinder 302, causing the sliding stepped cylinder 302 to move downwards driven by the helium in the second chamber. During the downward movement of the sliding stepped cylinder 302, the fan 303 moves downwards synchronously, thereby reducing the gap between the fan 303 and the air restrictor 304. This allows more air to pass through the air restrictor 304 and leave chamber 1 when the fan 303 draws air downwards, thus accelerating the airflow within chamber 1. The air is discharged from the ventilation hole 101 of the enclosure 1, thereby accelerating the entry of outside air into the enclosure 1. After a brief contact with the air inside the enclosure 1, the outside air is quickly discharged by the fan 303. The rapid airflow inside the enclosure 1 keeps the temperature inside the enclosure 1 low enough not to damage the electrical equipment. The rapid airflow in the enclosure 1 also creates a local low-pressure zone inside the enclosure 1. This causes the airflow around the electrical equipment to absorb the heat generated by the electrical equipment and then actively move towards the airflow at the fan 303 and merge with the airflow through the air pressure difference inside the enclosure 1, thereby accelerating the cooling speed of the electrical equipment. In addition, the sealing frame 502 and the pressure plate 503 form a third cavity. It is worth noting that in the initial state, the pressure plate 503 is located in the sealing frame. In the middle of 502, due to the decrease in air pressure inside the enclosure 1 during rainy weather, the air pressure in the third cavity is greater than the air pressure of the airflow inside the enclosure 1. The air in the third cavity pushes the pressure plate 503 to move horizontally. The movement of the pressure plate 503 drives the slide rod 506 to slide upward along the guide frame 505 via the connecting rod 504. This causes the slide rod 506 to drive the sliding ventilation plate 501 to move upward, thus making the second ventilation slot of the sliding ventilation plate 501 and the first ventilation slot of the enclosure door 2 completely connected. This accelerates the entry of outside air into the enclosure 1, speeds up the airflow renewal rate inside the enclosure 1, and prevents the air pressure inside the enclosure 1 from being too low, which would slow down the airflow and interfere with the absorption of heat from the electrical equipment by the airflow inside the enclosure 1.
