Description

Technical Field

[0001] The present application relates to the technical field of distribution box design, and in particular to a distribution box with a multi-level heat dissipation structure. Background Art

[0002] The distribution box is an indispensable device in the power system, which is used to accommodate and protect distribution equipment, such as circuit breakers, contactors, relays, transformers, control modules, etc. These devices generate a lot of heat during operation, especially under high load conditions. The heat accumulation will cause the temperature of the equipment to rise, which will affect its performance and life. In the western region, outdoor distribution boxes often face extreme environmental conditions, such as high temperature, strong wind, sand and dust, which puts higher requirements on the heat dissipation performance of the distribution box.

[0003] Traditional outdoor distribution boxes usually use natural air cooling or forced air cooling to dissipate heat. Natural air cooling relies on air convection, has low heat dissipation efficiency, and is difficult to cope with high heat loads. Forced air cooling uses fans to enhance air flow. Although it improves heat dissipation efficiency, the performance of the fan will be affected in high temperature environments, and strong winds may cause air duct disorder, which in turn reduces the heat dissipation effect. In addition, the high wind speed environment in the western region may cause uneven heat distribution inside the distribution box, frequent local overheating, and further aggravate the aging and failure risks of the equipment. In view of this, the present invention is proposed. Summary of the invention

[0030] Reference Figures 1 to 5 The present application first provides a distribution box 100 with a multi-level heat dissipation structure, the distribution box 100 includes a shell 10, a partition assembly 20, a movable structure 30 and a controller 40; the partition assembly 20 is arranged inside the shell 10, the movable structure 30 can be movably connected to the outer wall of the shell 10, and the controller 40 is arranged inside.

[0031] The housing 10 includes a first air inlet 11 and a second air inlet 12 which are opposite to each other in the horizontal direction and have a height difference, wherein the first air inlet 11 and the second air inlet 12 are respectively provided with a plurality of first air inlet ports 11a and second air inlet ports 12a, and the interior of the housing 10 is a receiving chamber A;

[0032] The partition assembly 20 includes a first separation partition 21 and a second separation partition 22. The first separation partition 21 divides the accommodating chamber A into a first air inlet chamber a1, a second air inlet chamber a2 and a main chamber a3 in the horizontal direction. The first air inlet chamber a1 and the second air inlet chamber a2 have a height difference.

[0033] The second separation partition 22 is disposed in the main chamber a3 and divides the main chamber a3 into a first element area a31 and a second element area a32;

[0034] The movable structure 30 is rotatably connected to the first air inlet 11 and the second air inlet 12, and includes a hinge mechanism 31 and a fin 32 connected to the hinge mechanism 31;

[0035] The controller 40 is configured to:

[0036] According to the current environmental conditions, the hinge mechanism 31 of the first air inlet 11 and the second air inlet 12 is controlled to change the angle u of the fin 32 at the corresponding surface relative to the first air inlet 11a and the second air inlet 12a, and / or the air flow direction in the first air inlet cavity a1, the first component area a31, and the first air inlet cavity a2 and the first component area;

[0037] The environmental status includes wind direction status, particle data, wind speed data and external temperature.

[0038] It can be understood that the housing 10 is the external structure of the distribution box, and a receiving cavity A is formed inside;

[0039] On the opposite and front surfaces, or the left and right opposite surfaces of the shell 10, there are two horizontally opposite air inlet holes with a height difference: a first air inlet hole 11 and a second air inlet hole 12. The two air inlet holes are respectively provided with a plurality of first air inlet ports 11a and a second air inlet port 12a, allowing external air flow to enter the interior of the shell from different heights of the opposite surfaces, thereby facilitating diversion and achieving thermal isolation.

[0040] The partition assembly 20 includes a first separation partition 21 and a second separation partition 22; the first separation partition 21 divides the accommodating chamber A into three parts in the horizontal direction: the first air inlet chamber a1, the second air inlet chamber a2 and the main chamber a3. The first air inlet chamber a1 and the second air inlet chamber a2 have a height difference in height, which helps to form an air flow gradient and achieve thermal separation. The second separation partition 22 further divides the main chamber a3 into a first element area a31 and a second element area a32.

[0041] The movable structure 30 includes a hinge mechanism 31 and fins 32, which can be rotatably connected to the first air inlet 11 and the second air inlet 12; the angle u of the fin 32 can be adjusted by the hinge mechanism 31, thereby changing the air volume of the air inlet and maintaining the first air inlet 11a and the second air inlet 12a to adapt to different environmental conditions.

[0042] The controller 40 intelligently controls the movable structure 30 and the air duct flow direction according to the current environmental conditions (such as wind direction, wind speed, particle data and external temperature).

[0043] Specifically, the controller 40 can adjust the angle u of the fin 32 to optimize the wind direction and air volume of the air inlet, and to achieve protection in different modes; at the same time, it controls the flow direction of the air duct in the first air inlet cavity a1, the first element area a31 and the second air inlet cavity a2, the second element area a32, specifically the circulating air duct and the one-way air duct.

[0044] Through the multi-level heat dissipation structure, the distribution box 100 can effectively discharge the internal heat to prevent the equipment from overheating. At the same time, the chambers can achieve thermal isolation, avoid heat interference between internal components, and improve the heat dissipation effect.

[0045] More specifically, the controller 40 can automatically adjust the angle of the fins 32 and the direction of the air duct flow according to the environmental conditions (such as wind direction, wind speed, temperature, etc.) to ensure that the best heat dissipation effect can be achieved under different environmental conditions. This intelligent adjustment not only improves the heat dissipation efficiency, but also reduces the need for manual intervention; due to the presence of the movable structure 30 and the controller 40, the distribution box 100 can adapt to various complex environmental conditions. For example, when the wind direction changes, the controller can automatically adjust the angle of the fins to ensure effective air intake at the air inlet and effectively protect the operation of the internal control components; in a high temperature environment, the controller can optimize the direction of the air duct flow, enhance heat dissipation, reduce the interference of the external environment on the internal components, and extend the life of the equipment, especially in outdoor environments, where the equipment is often faced with high temperature, high humidity, wind and sand and other harsh conditions; at the same time, through the intelligent control of the heat dissipation system, the distribution box 100 can reduce unnecessary energy consumption while ensuring the heat dissipation effect.

[0046] Moreover, the partition design of the partition assembly 20 makes the internal structure of the distribution box more modular, which is convenient for maintenance and transformation and upgrading; the independent heat dissipation design of different component areas also helps to solve the heat dissipation problems of different components in a targeted manner.

[0047] In a specific embodiment, the shell 10 is provided with a first air outlet 13 at the top, and the second air outlet 14 is provided at the second separation partition 21; the first air outlet 13 can connect the second element area a32 with the outside, and the second air outlet 14 can connect the first element area a31 with the outside, and the first air outlet 13 is provided with a first closable fan (not shown in the figure), and the second air outlet 14 is provided with a second closable fan (not shown in the figure);

[0048] The controller is also connected to the first closable fan and the second closable fan, and is further configured to:

[0049] Step S11, determining a first mode according to the environmental state, the first mode being that the current wind speed data is lower than a preset wind speed threshold, and the particle data is lower than a preset particle threshold;

[0050] Step S12: in the first mode, controlling the first closable fan to be connected to the first air outlet 13 and the second closable fan to be connected to the second air outlet 14;

[0051] Step S13, controlling the fin 32 to be at a first angle relative to the first air inlet 11a and the second air inlet 12a;

[0052] Step S14, control the first closable fan to start, so that the first air inlet hole 11a, the first air inlet cavity a1, the first component area a31 and the second air outlet 14 constitute a first air duct, and the second air inlet hole 12a, the second air inlet cavity a2, the second component area a32 and the first air outlet 13 constitute a second air duct.

[0053] Wherein, the first air duct and the second air duct are both unidirectional air ducts.

[0054] The first air outlet 13 is located at the top of the shell 10, connecting the second element area a32 and the outside world, and is used to discharge the hot air in the second element area; the second air outlet 14 is located at the second separation partition 21, connecting the first element area a31 and the outside world, and is used to discharge the hot air in the first element area; the first closable fan and the second closable fan are respectively arranged at the first air outlet 13 and the second air outlet 14, and are used to control the opening and closing of the air duct to ensure the unidirectional flow of the air duct.

[0055] The controller 40 determines whether to enter the first mode according to the environmental status (wind speed data and particle data).

[0056] The condition of the first mode is that the current wind speed is lower than the preset wind speed threshold and the particle concentration is lower than the preset particle threshold. In this mode, the natural convection effect is weak and the external environment is relatively clean, which is suitable for one-way heat dissipation assisted by a fan.

[0057] Step S12: In the first mode, the controller 40 controls the first closable fan and the second closable fan to connect to the first air outlet 13 and the second air outlet 14 respectively, ensuring that both air ducts are in an open state;

[0058] Step S13: The controller 40 adjusts the angle of the fin 32 so that it is at a first angle relative to the first air inlet 11a and the second air inlet 12a; the first angle is optimized according to the current environmental conditions, specifically, it is tilted downward by q1 degrees relative to the vertical angle, which can guide rainwater and block sand and dust, while ensuring that the air volume is moderate and the wind direction is stable;

[0059] Step S14: The controller 40 starts the first closable fan to form two one-way air ducts:

[0060] First air duct: air enters from the first air inlet hole 11a, passes through the first air inlet cavity a1, flows into the first component area a31, and finally is discharged through the second air outlet 14;

[0061] Second air duct: air enters from the second air inlet hole 12 a, passes through the second air inlet cavity a2, flows into the second component area a32, and is finally discharged through the first air outlet 13.

[0062] It can be understood that the controller 40 automatically selects the operating mode according to the environmental conditions to ensure efficient heat dissipation under different conditions. For example, when the wind speed is low and there are fewer particles, the fan is started to assist in heat dissipation to avoid a decrease in heat dissipation efficiency due to insufficient natural convection. The first air duct and the second air duct are both one-way air ducts from top to top, which conform to the gas flow characteristics of hot air, avoid heat accumulation, ensure that hot air can be discharged quickly and effectively, and at the same time, cold air can smoothly enter to form stable heat dissipation. Through the independent design of the first air duct and the second air duct, the heat dissipation of the first component area a31 and the second component area a32 can be optimized separately. This zoned heat dissipation method is particularly suitable for situations where the internal components generate uneven heat, ensuring that the heat dissipation needs of each area can be met, while avoiding heat pollution.

[0063] A third closable fan 15 is provided between the first air inlet cavity a1 and the first component area a31, and a fourth closable fan 16 is provided between the second air inlet cavity a2 and the second component area a32;

[0064] The controller is also configured to:

[0065] Step S21, determining the second mode according to the environmental state, the second mode is that the current wind speed data is greater than a preset wind speed threshold, and the particle data is lower than a preset particle threshold, and the wind direction is from the first air inlet 11a to the second air inlet 12a;

[0066] Step S22, in the second mode, controlling the fourth closable fan 16 to connect the second air inlet cavity a2 and the second element area a32;

[0067] Step S23, controlling the fin 32 to be at a first angle relative to the first air inlet 11a and at a second angle relative to the second air inlet 12a;

[0068] Step S24, control the first closable fan, the second closable fan and the fourth closable fan to start, so that the first air inlet hole 11a, the first air inlet cavity a1, the first component area a31 and the second air outlet 14 constitute a first air duct, the second air inlet hole 12a, the second air inlet cavity a2, the second component area a32 and the first air outlet 13 constitute a second air duct, and at the same time, the second air inlet hole 12a, the second air inlet cavity a2 and the second component area a32 simultaneously constitute a first circulation air duct.

[0069] The current wind speed is greater than the preset wind speed threshold, indicating that the external wind is strong and natural wind can be used to enhance heat dissipation; the particulate matter data is lower than the preset particulate matter threshold, indicating that the external air is relatively clean and suitable for directly introducing external air for heat dissipation; the wind direction is from the first air inlet 11a to the second air inlet 12a, and the wind direction is consistent with the layout direction of the first air inlet 11a. At this time, the air inlet and wind direction of the second air inlet 12a are likely to cause air duct turbulence.

[0070] The controller 40 determines to enter the second mode, and controls the fourth closable fan 16 to connect the second air inlet chamber a2 and the second component area a32. The function of the fourth closable fan 16 is to form two-way convection on the relatively upwind side, thereby enhancing the air flow between the second air inlet chamber a2 and the second component area a32, avoiding convection turbulence between the air duct and the external environment, and ensuring the stability of heat dissipation through internal circulation design.

[0071] The fin 32 is adjusted to a first angle relative to the first air inlet 11a to optimize the air intake; the fin 32 is adjusted to a second angle relative to the second air inlet 12a, and the second angle u value is smaller than the first angle; air can enter the second air inlet cavity a2 at a larger flow rate to increase the air intake and ensure smooth air flow.

[0072] Similarly, in the first air duct, air enters from the first air inlet hole 11 a , passes through the first air inlet cavity a1 , flows into the first component area a31 , and is finally discharged through the second air outlet 14 .

[0073] Second air duct: air enters from the second air inlet hole 12 a, passes through the second air inlet cavity a2, flows into the second component area a32, and is finally discharged through the first air outlet 13.

[0074] First circulation air duct: air enters from the second air inlet hole 12a, passes through the second air inlet cavity a2, flows into the second element area a32, and then flows back to the second air inlet cavity a2 through the fourth closable fan 16, forming an internal circulation.

[0075] Similarly, the first air duct and the second air duct respectively dissipate heat for the first component area a31 and the second component area a32 to ensure that the heat dissipation requirements of different areas are met; and the second mode takes the influence of wind direction into consideration by adjusting the angle of the fins 32 and the layout of the air duct to ensure that the air flow direction is consistent with the wind direction, avoiding air duct conflict or backflow, and at the same time ensuring the heat dissipation performance of the second component area a32 under headwind.

[0076] The controller 40 is also configured to:

[0077] Step S31, determining the third mode according to the environmental state, the third mode being that the current wind speed data is greater than a preset wind speed threshold, and the particle data is lower than a preset particle threshold, and the wind direction is from the second air inlet to the first air inlet;

[0078] Step S32, in the third mode, controlling the third closable fan to connect the first air inlet cavity and the first component area;

[0079] Step S33, controlling the fin to have a second angle relative to the first air inlet and a first angle relative to the second air inlet;

[0080] Step S34, control the first closable fan and the third closable fan to start, so that the second air inlet hole, the second air inlet cavity, the second component area and the first air outlet constitute a second air duct, and the first air inlet hole, the first air inlet cavity, the first component area constitute a second circulation air duct.

[0081] Similar to the above, the current wind speed is greater than the preset wind speed threshold, indicating that the external wind is strong and natural wind can be used to enhance heat dissipation; the particulate matter data is lower than the preset particulate matter threshold, indicating that the external air is relatively clean and the wind direction is from the second air inlet 12a to the first air inlet 11a; when the wind speed is high, the third mode makes full use of natural wind force, and by adjusting the angle of the fin 32, ensures that the air volume at the air inlet matches the wind direction, adapts to changes in wind direction, and maximizes the heat dissipation effect of natural wind. The second air duct and the second circulation air duct respectively dissipate heat for the second component area a32 and the first component area a31 to ensure that the heat dissipation needs of different areas are met. The design of the second circulation air duct further enhances the heat dissipation effect of the first component area a31 to avoid heat accumulation.

[0082] The controller 40 is also configured to:

[0083] Step S41, determining the fourth mode according to the environmental state, the fourth mode only needs to satisfy the condition that the particle data is greater than a preset particle threshold;

[0084] Step S42, in the fourth mode, the first closable fan is controlled to close the first air outlet 13, the second closable fan is controlled to close the second air outlet 14, the third closable fan is connected to the first air inlet cavity a1 and the first component area a31, and the fourth closable fan is connected to the second air inlet cavity a2 and the second component area a32;

[0085] Step S43, controlling the fin 32 to be at a third angle relative to the first air inlet 11a and the second air inlet 12a;

[0086] Step S44, control the third closable fan and the fourth closable fan to start, so that the second air inlet hole 12a, the second air inlet cavity a2, and the second element area a32 constitute a first circulation air duct, and the first air inlet hole a1, the first air inlet cavity a1, and the first element area a31 constitute a second circulation air duct.

[0087] The particle data is greater than the preset particle threshold, indicating that the external air contains more particulate matter and is not suitable for unidirectional introduction of external air for heat dissipation. The fourth mode only needs to satisfy that the particle data is greater than the preset threshold, and there is no need to consider wind speed and wind direction; the controller 40 determines to enter the fourth mode and closes the air vents directly connected to the outside to prevent external pollutants from entering. Specifically, the first closable fan is controlled to close the first air outlet 13, and the second closable fan is controlled to close the second air outlet 14.

[0088] The third closable fan is controlled to connect the first air inlet chamber a1 and the first component area a31; the fourth closable fan is connected to the second air inlet chamber a2 and the second component area a32, and the fins 32 are adjusted to a third angle relative to the first air inlet 11a and the second air inlet 12a (the u value of the third angle is greater than the first angle) to reduce the entry of external air while ensuring the smoothness of the internal air flow; the air circulates between the second air inlet hole 12a, the second air inlet chamber a2, and the second component area a32, and at the same time, the air circulates between the first air inlet hole 11a, the first air inlet chamber a1, and the first component area a31.

[0089] When the external air quality is poor, the fourth mode prevents external particles from entering the distribution box and protects the internal components from pollution by closing the air outlets (the first air outlet 13 and the second air outlet 14) that are directly connected to the outside; an internal circulation air duct is formed by starting the third closable fan and the fourth closable fan to ensure that heat can be effectively discharged from the inside; the fins 32 are adjusted to a third angle, which reduces the entry of external air and ensures the smoothness of the internal air flow, thereby avoiding a decrease in heat dissipation efficiency due to the external environment. At the same time, since the first circulation air duct and the second circulation air duct are designed with an air flow from bottom to top, after entering the air duct, the particles will move upward with the airflow, while the heavier particles will gradually settle due to gravity, reducing the possibility of entering the component area.

[0090] The controller is also configured to:

[0091] Step S51, determining a fifth mode according to the environmental state, wherein the fifth mode is that the external temperature is less than a preset temperature threshold and the particulate matter data is less than a preset particulate matter threshold;

[0092] Step S52, in the fifth mode, controlling the first closable fan to connect to the first air outlet, the second closable fan to connect to the second air outlet, controlling the third closable fan to connect to the first air inlet cavity and the first component area, and controlling the fourth closable fan to connect to the second air inlet cavity and the second component area;

[0093] Step S53, controlling the fin to have a second angle relative to the first air inlet and the second air inlet;

[0094] Step S54, control the first closable fan, the second closable fan, the third closable fan and the fourth closable fan to stop.

[0095] If the external temperature is lower than the preset temperature threshold, it indicates that the external environment temperature is low and the natural heat dissipation effect is better; if the particle matter data is lower than the preset particle matter threshold, it indicates that the external air quality is good and it is suitable to directly introduce external air for heat dissipation.

[0096] The first closable fan is connected to the first air outlet 13, the second closable fan is connected to the second air outlet 14, the third closable fan is connected to the first air inlet chamber a1 and the first component area a31, and the fourth closable fan is connected to the second air inlet chamber a2 and the second component area a32; the fins 32 are adjusted to a second angle relative to the first air inlet 11a and the second air inlet 12a to optimize the air intake volume; the first closable fan, the second closable fan, the third closable fan and the fourth closable fan are all controlled to stop.

[0097] When the outside temperature is low and the air quality is good, the fifth mode stops all fans to reduce energy consumption and achieve energy-saving operation. By adjusting the angle of the fins 32 and the connecting air ducts, the fifth mode makes full use of natural wind and the natural rising characteristics of hot air to achieve efficient natural heat dissipation. When environmental conditions are suitable, the fifth mode simplifies the operation mode of the equipment and reduces maintenance costs. By reducing the operating time of the fan, the fifth mode can extend the service life of the fan and reduce the maintenance cost of the equipment.

[0098] Furthermore, at least one placement rack 23 is disposed in the first element area a31 and the second element area a32; the placement rack 23 is a heat exchange copper plate and is hollowed out.

[0099] The placement rack 23 is used to fix and support the electronic components in the first component area a31 and the second component area a32 to ensure their stable operation; the hollowing allows air to freely pass through the placement rack 23, forming a more uniform airflow distribution and avoiding heat accumulation; at the same time, the contact area between the copper plate and the airflow is increased, thereby improving the heat dissipation efficiency; the weight of the copper plate is reduced, thereby reducing the load on the overall equipment; the placement rack 23 can quickly conduct the heat generated by the components to the surrounding air to avoid local overheating.

[0100] The side of the fin 32 facing away from the first air inlet hole 11a and the second air inlet hole 12a is a reflective surface; the reflective surface is usually made of a material with high reflectivity (such as mirror stainless steel, aluminum-plated or silver-plated material), which can effectively reflect heat from solar radiation and other external heat sources; the design of the reflective surface enables the fin 32 to reduce the absorption of external heat in an outdoor environment and lower the temperature of the fin itself.

[0101] The inner wall of the housing 10 is also provided with a mounting rail 24 , and the placement racks 23 are all slidably connected to the mounting rail 24 so as to be able to change their positions within a preset stroke.

[0102] Through the sliding connection design, the placement rack 23 can be flexibly adjusted according to the size, heat generation or installation requirements of the component to optimize the internal space utilization. For example, components with higher heat generation can be placed near the air duct outlet to enhance the heat dissipation effect. The sliding design of the placement rack 23 makes the installation, removal and maintenance of the components more convenient. Maintenance personnel can easily pull out the placement rack 23 to replace or repair the components. When upgrading the equipment, the position of the placement rack 23 can be adjusted according to the size and heat dissipation requirements of the new components.

[0103] Continue reading Figure 6 The first air outlet 13 is provided with a fan slide rail 25, the first closable fan 31 is slidably connected to the fan slide rail 25, and includes a first fan part 311 and first baffle parts 312 on both sides; when the first closable fan 31 moves to a preset first position, the first fan part 311 is connected to the first air outlet 13; when the first closable fan 31 moves to a preset second position, the first baffle part 312 closes the first air outlet 13, and the remaining second closable fans, third closable fans and fourth closable fans are the same as above, and the present application does not list them one by one.

[0104] In simple terms, the design of the slide rail enables the first closable fan 31 to slide along the slide rail, which is convenient for adjusting the position. The first fan part 311 is used to connect to the first air outlet 13, enhance air flow, and improve the heat dissipation effect. The first baffle part 312 is located on both sides of the first fan part 311, and is used to close the first air outlet 13, play a blocking role and prevent external air from entering. When the first closable fan 31 moves to the first position, the first fan part 311 is connected to the first air outlet 13 to enhance air flow. When the first closable fan 31 moves to the second position, the first baffle part 312 closes the first air outlet 13 to prevent external air from entering. Through the sliding connection design, the first closable fan 31 can adjust its position according to actual needs and flexibly control the opening and closing of the air duct.
