Description

Technical Field

[0001] This utility model relates to the field of power distribution cabinet technology, and in particular to a removable power distribution cabinet with a circulating heat conduction mechanism. Background Technology

[0002] A removable switchgear is a high-voltage switchgear equipped with removable functional units (such as circuit breaker trolleys). Its core feature is that it allows for convenient isolation, maintenance, or replacement of major electrical components by removing them. It is mainly used for receiving, distributing, and controlling electrical energy, and has overload and short-circuit protection functions. It is widely used in places with high requirements for power supply reliability and operational safety, such as industrial and mining enterprises, power plants, substations, and power distribution systems in large commercial buildings or residential communities, to ensure the safe and flexible operation of the power system.

[0003] Because the hot air generated by the long-term operation of the distribution cabinet will rise and accumulate inside it, the existing removable distribution cabinet with circulating heat conduction mechanism only uses ordinary liquid cooler and fan to directly impact the hot air for heat dissipation. During the heat conduction process, it is difficult to disperse and expel the accumulated hot air, resulting in heat still accumulating above the distribution cabinet, which affects the normal operation of electronic components. Utility Model Content

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a removable distribution cabinet with a circulating heat conduction mechanism, comprising: a cabinet body, a liquid cooler disposed on the upper side of the cabinet body, a transformer disposed inside the upper end of the cabinet body, and multiple exhaust fans disposed on the outer walls of the lower two sides of the cabinet body; and circulating heat conduction components, two circulating heat conduction components disposed opposite to each other inside the cabinet body, the two circulating heat conduction components not on the same horizontal line, the circulating heat conduction components being used to dissipate heat from the cabinet body when it is in operation.

[0006] In a preferred embodiment, the circulating heat conduction assembly includes: a blower chamber, two blower chambers are fixedly connected to both sides of the cabinet, the two blower chambers are not on the same horizontal line, the air outlets of the two blower chambers are respectively inserted into the fixed slots opened on the sides of the cabinet, and the two blower chambers are respectively fixedly connected to the inclined air guide chambers at one end of the air outlet inside the cabinet, and the lower inner walls of the two inclined air guide chambers are respectively provided with multiple long slots.

[0007] In a preferred embodiment, the circulating heat conduction assembly further includes: two serpentine cooling pipes, each disposed inside a corresponding air chamber, with the inlet and outlet ends of the two serpentine cooling pipes passing through the side wall of the air chamber, and their ports arranged outside the air chamber; and two mounting plates, each disposed inside a corresponding air chamber, with the mounting plates located on the side of the serpentine cooling pipes away from the inclined air guide chamber.

[0008] In a preferred embodiment, the circulating heat conduction assembly further includes: a rotating shaft, wherein multiple rotating shafts are respectively connected to multiple rotating holes opened on one side of two mounting plates via bearings, and multiple fan blades are respectively provided on the outer wall of the end of the multiple rotating shafts located on the same mounting plate near the serpentine cooling pipe, and the same transmission belt is provided on the outer wall of the other end of the multiple rotating shafts; a rotating motor, wherein two rotating motors are respectively fixedly connected to one side of the corresponding mounting plate, and the drive end of the rotating motor is connected to one end of the corresponding rotating shaft via a coupling; and an L-shaped fixing plate, wherein two L-shaped fixing plates are respectively fixedly connected to the inner walls of the upper two sides of the cabinet, and the two L-shaped fixing plates are respectively located on the same horizontal line as the corresponding inclined air guide chamber.

[0009] In a preferred embodiment, the circulating heat conduction assembly further includes: arc-shaped air guide plates, two arc-shaped air guide plates are respectively fixedly connected to the interior of corresponding L-shaped fixed plates, the lower ends of the two arc-shaped air guide plates are respectively connected to adjusting rods via bearings, the outer walls of the two adjusting rods are fixedly connected to limiting sleeves, the outer walls of the two limiting sleeves are respectively provided with limiting slots, the outer walls of the two adjusting rods are respectively connected to turbulence guide plates via bearings, the two turbulence guide plates are located inside the corresponding limiting sleeves, and one end of the two turbulence guide plates passes through the limiting slots provided in the corresponding limiting sleeves and is located outside them.

[0010] In a preferred embodiment, the circulating heat conduction assembly further includes: torsion springs, wherein multiple torsion springs are respectively sleeved on the outer wall of the corresponding adjusting rod at equal intervals, one end of two torsion springs located on the outer wall of the same adjusting rod is fixedly connected to both ends of the turbulence guide plate, and the other end is fixedly connected to the inner walls of both ends of the limiting sleeve; and adjusting motors, wherein two adjusting motors are respectively fixedly connected to one end of the corresponding L-shaped fixing plate, and the driving end of the adjusting motor is connected to one end of the corresponding adjusting rod through a coupling.

[0011] In a preferred embodiment, the outlet and inlet ends of the two serpentine cooling tubes are respectively inserted into one end of the circulation tube, and the other ends of the multiple circulation tubes are respectively connected and fixed to the liquid cooler.

[0012] As can be seen from the above, the removable distribution cabinet with a circulating heat conduction mechanism provided by this utility model utilizes the circulating heat conduction component to blow cold air into the cabinet for cooling. The cold air then enters the cabinet at an upward angle through an inclined air guide chamber, causing initial turbulence to the accumulated hot air and dispersing it. When the cold air changes direction through the arc-shaped air guide plate and passes through the turbulence guide plate at a downward angle, it causes secondary turbulence to the hot air, carrying the dispersed hot air downwards and finally exhausting it through the exhaust fan. By turbulently dispersing and expelling the accumulated hot air twice, a circulating heat dissipation system is achieved, where cold air enters through the circulating heat conduction component and hot air is quickly exhausted through the exhaust fan. This not only improves heat dissipation efficiency but also prevents excessive heat accumulation on the upper inner wall of the cabinet, which could affect the operation of electronic components.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] The removable distribution cabinet with a circulating heat conduction mechanism disclosed in this utility model is mainly used in scenarios where the heat dissipation system of existing removable distribution cabinets is difficult to effectively disperse and expel the hot air accumulated above the interior, resulting in continuous heat accumulation and affecting the normal operation of electronic components.

[0026] In this scheme, the circulating heat conduction assembly 3 also includes: a rotating shaft 305, multiple rotating shafts 305 are respectively connected to multiple rotating holes opened on one side of two mounting plates 304 through bearings, multiple fan blades 307 are respectively provided on the outer wall of the end of the multiple rotating shafts 305 located on the same mounting plate 304 near the serpentine cooling pipe 309, and the same transmission belt 306 is provided on the outer wall of the other end of the multiple rotating shafts 305; a rotating motor 308, two rotating motors 308 are respectively fixedly connected to one side of the corresponding mounting plate 304, and the drive end of the rotating motor 308 is connected to one end of the corresponding rotating shaft 305 through a coupling; and an L-shaped fixing plate 301, two L-shaped fixing plates 301 are respectively fixedly connected to the inner walls of the upper two sides of the cabinet 2, and the two L-shaped fixing plates 301 are respectively located on the same horizontal line as the corresponding inclined air guide chamber 303.

[0027] In this scheme, the circulating heat conduction component 3 further includes: an arc-shaped air guide plate 310, two arc-shaped air guide plates 310 are respectively fixedly connected to the interior of the corresponding L-shaped fixed plate 301, the lower ends of the two arc-shaped air guide plates 310 are respectively connected to adjusting rods 314 through bearings, the outer walls of the two adjusting rods 314 are fixedly connected to limiting sleeves 312, the outer walls of the two limiting sleeves 312 are respectively opened with limiting slots, the outer walls of the two adjusting rods 314 are respectively connected to turbulence guide plates 313 through bearings, the two turbulence guide plates 313 are located inside the corresponding limiting sleeves 312, and one end of the two turbulence guide plates 313 passes through the limiting slots opened in the corresponding limiting sleeves 312 and is located outside them.

[0028] In this scheme, the circulating heat conduction component 3 also includes: torsion springs 315, multiple torsion springs 315 are respectively sleeved on the outer wall of the corresponding adjusting rod 314 at equal intervals, one end of two torsion springs 315 located on the outer wall of the same adjusting rod 314 is fixedly connected to both ends of the turbulence guide plate 313, and the other end is fixedly connected to the inner walls of both ends of the limiting sleeve 312; adjusting motors 311, two adjusting motors 311 are respectively fixedly connected to one end of the corresponding L-shaped fixing plate 301, and the driving end of the adjusting motor 311 is connected to one end of the corresponding adjusting rod 314 through a coupling.

[0029] When cooling the removable distribution cabinet, the inclined air guide chamber 303 is tilted and has multiple long slots on its lower inner wall. Therefore, the cold air first contacts the lower inner wall, causing dust carried in the cold air to remain inside the long slots, thus reducing the inflow of dust into the cabinet 2 and ensuring the normal operation of electronic components. The cold air entering the cabinet 2 at an upward angle first turbulences the accumulated hot air as it flows towards the corresponding arc-shaped air guide plate 310, initially dispersing the accumulated hot air. When the cold air changes direction through the arc-shaped air guide plate 310 and passes through the turbulence guide plate 313 at a downward angle, it further turbulents the hot air, carrying the dispersed hot air downwards from the cabinet 2. Finally, the air is exhausted through the exhaust fan 1. By adjusting the motor 311, the adjusting rod 314 drives the limiting sleeve 312 to rotate the baffle 313. This allows the angle of the baffle 313 to be adjusted according to the amount of heat inside the cabinet 2, making the airflow adaptable and improving the heat dissipation effect. At the same time, since the baffle 313 is rotatably connected to the adjusting rod 314 and can deflect a certain distance under the action of the torsion spring 315 and the limiting sleeve 312, the flow rate of cold air passing through the baffle 313 is not constant. Therefore, the baffle 313 will vibrate during the process of transporting cold air, thus creating fluctuations in the cold air and improving the baffle efficiency.

[0030] Reference Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 7 In a preferred embodiment, the outlet and inlet ends of the two serpentine cooling tubes 309 are respectively connected to one end of the circulation tube 4, and the other ends of the multiple circulation tubes 4 are respectively connected and fixed to the liquid cooler 5.

[0031] Working Principle: When the removable distribution cabinet with a circulating heat conduction mechanism is working, its internal electronic components generate a large amount of heat. This heat, along with the air, rises and accumulates inside the distribution cabinet. At this time, by turning on the rotary motor 308, multiple rotating shafts 305 are driven by the transmission belt 306 to rotate, and combined with the fan blades 307, air with a certain flow rate is formed. Subsequently, the air is cooled by the liquid cooler 5 and the serpentine cooling pipe 309 connected by the circulation pipe 4 to form cold air. Then, the cold air enters the cabinet 2 through the inclined air guide chamber 303 in an upward tangential direction. During this process, because the inclined air guide chamber 303 is inclined and has multiple long grooves on its lower inner wall, the cold air first contacts its lower inner wall, so that the dust carried in the cold air will be left in the long grooves, thereby reducing the inflow of dust into the cabinet 2 and ensuring the normal operation of the electronic components. The cold air entering the cabinet 2 in an upward tangential direction flows towards the corresponding arc-shaped air guide plate 310, which accumulates dust. The hot air undergoes an initial turbulence, initially dispersing the accumulated hot air. When the cold air passes through the arc-shaped air guide plate 310, it changes direction and passes through the turbulence guide plate 313 in a downward-sloping direction, causing a secondary turbulence that carries the dispersed hot air downwards towards the cabinet 2 and finally out through the exhaust fan 1. During this process, the motor 311 can drive the adjusting rod 314 to rotate the limiting sleeve 312, thereby adjusting the angle of the turbulence guide plate 313 according to the amount of heat inside the cabinet 2, adapting the wind speed to the changes and improving the heat dissipation effect. At the same time, since the turbulence guide plate 313 is rotatably connected to the adjusting rod 314 and can be deflected a certain distance by the torsion spring 315 and the limiting sleeve 312, the flow rate of the cold air passing through the turbulence guide plate 313 is not constant. Therefore, the turbulence guide plate 313 will vibrate during the delivery of cold air, thus creating fluctuations in the cold air and improving the turbulence efficiency.

The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
