Description

Technical Field

[0001] The invention relates to the technical field of rectifier cabinets, and in particular to a rectifier cabinet heat dissipation structure and a rectifier cabinet. Background Art

[0002] Rectifier cabinet is a kind of power equipment, its core function is to convert AC power into DC power to meet the power supply needs of electronic equipment. Rectifier cabinet is mainly used in power system to convert AC power into DC power to provide stable and reliable power supply for various DC equipment. It is widely used in telecommunications, transportation, water conservancy, energy, industry, petrochemical, communication, aerospace, railway and other fields.

[0003] The core function of the rectifier cabinet is to convert AC power into DC power. This conversion process involves the coordinated work of components such as the rectifier transformer, the rectifier (mainly composed of components such as thyristors or diodes), and the control unit. Among them, the rectifier is the main component that generates heat. When current passes through the rectifier, components such as thyristors will dissipate power, generate heat inside, and increase the temperature of the device. If this heat is not dissipated in time, it will have a serious impact on the performance and life of the rectifier cabinet. Therefore, a heat dissipation structure is required to dissipate heat from the rectifier cabinet.

[0004] In the prior art, an application document with publication number CN116634730A discloses a rectifier cabinet heat dissipation system, and also discloses that a ventilation structure is arranged at the opening position of the cabinet, and the gas circulation inside and outside the cabinet is realized through the channel interval formed in the peripheral wall portion to ensure the heat dissipation of the cabinet. At the same time, a filtering structure is arranged in the filtering interval of the peripheral wall portion, and the filtering effect of the filter element on dust is used to prevent dust from entering the interior of the cabinet and causing short circuit of components, thereby extending the service life of the cabinet.

[0005] For some large rectifier cabinets, various faults may occur during the operation of the cabinet, such as overheating, short circuit, component damage, etc. When these faults occur, maintenance personnel need to quickly enter the rectifier cabinet to troubleshoot and handle the faults. Therefore, the rectifier cabinet is equipped with a door for personnel to enter and exit to ensure that maintenance personnel can enter the rectifier cabinet in time to perform necessary maintenance and replacement work. However, when personnel enter and exit the rectifier cabinet, the outside air will be directly exchanged with the inside of the rectifier cabinet, so the dust prevention effect cannot be achieved effectively.

[0028] Beneficial effects of the present invention:

[0029] When the rectifier cabinet body is cooled, the fan in the heat dissipation box on one side or both sides is turned on based on the heat dissipation demand, and the fan can draw the outside air into the heat dissipation cabinet through the vents to achieve the effect of air supply. When the outside air enters the heat dissipation box, the dust impurities in the air are filtered by the first filter plate to prevent the dust from entering the rectifier cabinet body at the same time and affecting the electrical equipment.

[0030] In the present invention, when the electric power personnel need to enter the rectifier cabinet body for inspection or maintenance, before opening the cabinet door, firstly, the opening is adjusted to a closed state by the adjustment module to separate the rectifier cabinet body from the heat dissipation cabinet, and then the cabinet door is opened. The electric power construction personnel wear dust-proof clothing and anti-static clothing to enter the heat dissipation cabinet and close the cabinet door, and then close the fan on one side and open the fan on the other side. After being turned on, the fan draws the outside air into the heat dissipation cabinet from the heat dissipation port on one side. Since the fan in the heat dissipation box on the other side is not turned on, the air entering the heat dissipation cabinet can be discharged from the heat dissipation port on this side for a period of time. In this process, the air entering the heat dissipation cabinet after the cabinet door is opened can be completely discharged from the heat dissipation port. In the present invention, when the air passes through the heat dissipation port and the heat dissipation box, the dust and impurities in the air are removed by the dust removal module arranged in the heat dissipation box. After the removal is completed, the opening is adjusted to open by the adjustment module, and the electric power personnel can enter the rectifier cabinet body to operate. The present invention can fully filter the air delivered to the rectifier cabinet body, and even if the cabinet door is opened, dust or impurities will not be brought into the rectifier cabinet body.

[0031] In the present invention, when the rectifier cabinet body is in a normal heat dissipation state, the sealing plate is in a state of sealing the air trough, and at this time, the adjustment module also adjusts the opening to be in an open state, and the outside air can first enter the air guide channel from the heat dissipation port, and then be transported to the rectifier cabinet body. Correspondingly, when the adjustment module adjusts the opening to be closed, the push part drives the sealing plates on both sides to approach each other, so that the air trough is in an open state, then the air entering the air guide channel from the heat dissipation port on one side can first enter the heat dissipation cabinet through the air trough, and then be discharged from the air trough and the heat dissipation port on the other side in sequence, so as to achieve purification of the air in the heat dissipation cabinet;

[0032] In the present invention, when the first wind shield plates on both sides are driven close to each other, the first wind shield plates can synchronously drive the sealing disk to move, thereby opening the wind slot. The present invention does not need to set up other servo drive devices to adjust the movement of the sealing disk, and the wind slot can be opened while closing the opening, with higher stability and synchronization.

DETAILED DESCRIPTION

[0047] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] Example 1

[0049] See also Figure 1-Figure 3 As shown, the present invention is a rectifier cabinet heat dissipation structure, including a heat dissipation cabinet 2 arranged on one side of the rectifier cabinet main body 1, and an opening 204 connected to the rectifier cabinet main body 1 is provided on one side of the heat dissipation cabinet 2; specifically, a cabinet door 201 is provided on the other side of the heat dissipation cabinet 2 away from the opening 204, and the cabinet door 201 can be opened and closed to facilitate power construction personnel to enter the rectifier cabinet main body 1 through the heat dissipation cabinet 2.

[0050] In this embodiment, the first heat dissipation module 3 and the second heat dissipation module 4 are symmetrically arranged on both sides of the heat dissipation cabinet 2, and the first heat dissipation module 3 and the second heat dissipation module 4 are used to input external air into the heat dissipation cabinet 2; specifically, during the operation of the rectifier cabinet body 1, the external air is input into the heat dissipation cabinet 2 through the first heat dissipation module 3 and the second heat dissipation module 4, and then transported to the rectifier cabinet body 1 through the opening 204, so as to perform heat dissipation treatment on the electrical equipment inside the rectifier cabinet body 1.

[0051] See also Figure 2-Figure 4 , the first heat dissipation module 3 and the second heat dissipation module 4 both include a heat dissipation box 301 fixedly arranged on the heat dissipation cabinet 2, and the heat dissipation cabinet 2 is correspondingly provided with a heat dissipation port 210 connected to the heat dissipation box 301, and the other end of the heat dissipation box 301 is provided with a vent 313, and a first filter plate 314 is fixedly embedded in the vent 313, wherein fans 304 are uniformly arranged in the heat dissipation box 301; it can be explained that, when the rectifier cabinet body 1 is cooled in this embodiment, based on the heat dissipation demand, the fans 304 in the heat dissipation boxes 301 on one side or both sides are turned on respectively, and the fans 304 can draw the outside air into the heat dissipation cabinet 2 through the vent 313 to achieve the effect of air supply, and in the process of the outside air entering the heat dissipation box 301, the dust and impurities in the air are filtered through the first filter plate 314 to prevent the dust from simultaneously entering the rectifier cabinet body 1 and affecting the electrical equipment.

[0052] As a further solution of this embodiment, an adjustment module is also arranged at the opening 204, and the adjustment module is used to adjust the opening or closing of the opening 204;

[0053] A dust removal module is also arranged in the heat dissipation box 301, and the dust removal module is used to remove dust from the air passing through the heat dissipation box 301;

[0054] It should be noted that when the power workers need to enter the rectifier cabinet body 1 for inspection or maintenance, before opening the cabinet door 201, first adjust the opening 204 to a closed state by adjusting the module to separate the rectifier cabinet body 1 from the heat dissipation cabinet 2, and then open the cabinet door 201. The power construction workers wear dust-proof clothing and anti-static clothing to enter the heat dissipation cabinet 2 and close the cabinet door 201, and then turn off the fan 304 on one side and turn on the fan on the other side. The specific details are not limited. After being turned on, the fan 304 draws the outside air into the heat dissipation cabinet 2 from the heat dissipation port 210 on one side. Since the fan 304 in the heat dissipation box 301 on the other side is not turned on, the air entering the heat dissipation cabinet 2 can be The side heat dissipation port 210 is discharged for a period of time. During this process, the air entering the heat dissipation cabinet 2 after the cabinet door 201 is opened can be completely discharged through the heat dissipation port 210. In this embodiment, when the air passes through the heat dissipation port 210 and the heat dissipation box 301, the dust and impurities in the air are removed by the dust removal module arranged in the heat dissipation box 301. After the removal is completed, the opening 204 is finally opened by adjusting the module, and the power staff can enter the rectifier cabinet body 1 to operate. This embodiment can fully filter the air delivered to the rectifier cabinet body 1, and even if the cabinet door 201 is opened, dust or impurities will not be brought into the rectifier cabinet body 1.

[0055] It should also be noted that since the first filter plate 314 is arranged at the air inlet end of the heat dissipation box 301, a layer of dust and impurities will adhere to its surface when it is running for a long time. When the fan 304 on one side is turned on, the air inlet end of the heat dissipation box 301 on the other side will also be switched to the air outlet end, and then the dust on the surface of the first filter plate 314 can be removed by the backblowing effect of the wind, thereby achieving a cleaning effect. Correspondingly, this embodiment can clean the first filter plates 314 at the air vents 313 on both sides by alternately turning on the fans 304 on both sides, without the need for manual regular cleaning and replacement, and thus achieving a better heat dissipation effect.

[0056] Example 2

[0057] Based on Example 1, please refer to Figure 4-Figure 6A through slot 305 is provided at the bottom of the heat dissipation box 301, and the dust removal module includes a second filter plate 302 embedded in the through slot 305, and also includes a lifting mechanism for driving the second filter plate 302 to rise and fall; it can be explained that when the rectifier cabinet body 1 is in normal operation, the second filter plate 302 is located outside the heat dissipation box 301. When the power staff enters the heat dissipation cabinet 2, when the fan 304 in the heat dissipation box 301 on one side is turned on, the second filter plate 302 is driven by the lifting mechanism to be embedded in the box along the through slot 305 at the bottom of the heat dissipation box 301 on the other side, so that when the air passes through the heat dissipation box 301, the dust and impurities in the air are filtered by the second filter plate 302. Correspondingly, when the filtering is completed, the second filter plate 302 is drawn out of the heat dissipation box 301 by the lifting mechanism, so as to facilitate the subsequent cleaning of the second filter plate 302.

[0058] In this embodiment, please refer to Figure 2 , Figure 6-Figure 7 In order to facilitate the lifting and lowering of the second filter plate 302, the two side walls of the heat dissipation box 301 are provided with slide grooves 311 connected to the through grooves 305. The two sides of the second filter plate 302 are fixed to the sleeve 501 through the connecting rod passing through the slide grooves 311. The sleeve 501 is connected to the positioning frame 507. The lifting mechanism includes a lifting module 203 fixedly arranged on the outside of the heat dissipation cabinet 2. The lifting module 203 is used to drive the positioning frame 507 to lift in the vertical direction. Specifically, the lifting module 203 of this embodiment can adopt a screw nut transmission mechanism or a synchronous belt transmission mechanism, which is not limited to this, as long as it can realize the driving of the positioning frame 507 to lift in the vertical direction.

[0059] It should be noted that in this embodiment, the lifting module 203 first drives the positioning frame 507 to move, and during the movement, the positioning frame 507 can synchronously drive the second filter plate 302 to slide along the slide groove 311 through the sleeve 501 and the connecting rod.

[0060] When the second filter plate 302 is separated from the heat dissipation box 301, in order to prevent air from entering the heat dissipation box 301 along the slide groove 311, in this embodiment, refer to Figure 7, a sealing plate 6 is slidably embedded in the slide grooves 311 on both sides, a limiting rod 602 is fixedly arranged on the heat dissipation box body 301, and a limiting plate 601 fixed to the sealing plates 6 on both sides is slidably arranged on the limiting rod 602, wherein a first spring 603 is provided on the limiting rod 602; specifically, one end of the first spring 603 is fixed to the limiting plate 601, and the other end is fixed to the top of the limiting rod 602; it can be explained that when the second filter plate 302 and the heat dissipation box body 301 are in a separated state, the sealing plates on both sides The bottom end of 6 extends to the through groove 305. As the second filter plate 302 slides upward along the slide groove 311, the sealing plates 6 on both sides can be pushed to rise synchronously along the slide groove 311. The sealing plates 6 on both sides drive the limit plates 601 to slide synchronously on the limit rods 602, thereby compressing the first spring 603. When the second filter plate 302 descends and separates from the heat dissipation box 301, the first spring 603 can synchronously drive the sealing plate 6 to reset through the limit plates 601 to seal the slide groove 311.

[0061] Accordingly, see Figure 4-Figure 5 In order to seal the through groove 305, a groove 306 is provided on one side of the groove wall of the through groove 305, a sealing seat 309 is slidably arranged in the groove 306, and an inclined guide surface 310 is provided at the bottom of the sealing seat 309 close to the through groove 305, wherein a second spring 307 is fixedly arranged in the groove 306, one end of the second spring 307 is fixed to the groove wall, and the other end is fixed to the sealing seat 309; it should be noted that when the second filter plate 302 and the heat dissipation box body 301 are in a separated state, the sealing seat 30 9 protrudes to the outside of the groove 306, and its end abuts against the groove wall of the through groove 305, thereby achieving the effect of sealing the through groove 305. As the second filter plate 302 moves along the through groove 305 toward the heat dissipation box 301, the top of the second filter plate 302 first abuts against the inclined guide surface 310. When the second filter plate 302 continues to rise, it can push the sealing seat 309 to shrink into the groove 306, so as to compress the second spring 307 and generate elastic force, so as to facilitate the subsequent driving of the sealing seat 309 to reset.

[0062] As a further solution of this embodiment, after the second filter plate 302 is dust-removed, in order to facilitate the removal of dust attached to its surface, please refer to Figure 6-Figure 7, the sleeve 501 is rotatably connected with the positioning frame 507, and the first gear 5 is fixedly arranged on the sleeve 501, wherein first racks 604 for meshing with the first gear 5 are respectively arranged on both sides of the bottom of the heat dissipation box 301; specifically, when the second filter plate 302 is driven to descend in the heat dissipation box 301, as the second filter plate 302 is completely separated from the heat dissipation box 301, the first gear 5 just moves to mesh with the first rack 604, and then drives the second filter plate 302 to continue to descend. During the descent, the first gear 5 can drive the sleeve 501 to rotate by meshing with the first rack 604, and the sleeve 501 synchronously drives the second filter plate 302 to rotate. When the first gear 5 is separated from the first rack 604, the second filter plate 302 rotates 90 degrees (see Fig.12 ), so that its windward side is just facing the ground, making it easier to remove dust.

[0063] See also Figure 7-Figure 8 In order to clean the dust attached to the surface of the second filter plate 302, in this embodiment, the positioning frames 507 on both sides are fixed to the U-shaped frame 508, and two groups of supports 509 are symmetrically fixed at the bottom of the U-shaped frame 508. The driving end of the lifting module 203 is fixed to the U-shaped plate 511, and the supports 509 are slidably connected to the guide rod 510 fixedly arranged in the U-shaped plate 511. Two groups of third springs 512 are symmetrically arranged on the guide rod 510, one end of the third spring 512 is fixed to the support 509, and the other end is fixed to the U-shaped plate 511, wherein the outer side of the heat dissipation cabinet 2 is correspondingly fixedly arranged with a toothed plate 308, and a guide wheel 312 is rotatably arranged on the U-shaped frame 508 close to the toothed plate 308. It can be explained that when the first After the second filter plate 302 rotates to a horizontal state, the lifting module 203 continues to drive the U-shaped frame 508 to descend, and the U-shaped frame 508 can drive the guide wheel 312 to roll and abut with the toothed plate 308. Under the pushing action of the toothed plate 308, the guide wheel 312 can push the U-shaped frame 508 to deviate to one side, and the U-shaped frame 508 drives the support 509 to slide on the guide rod 510, thereby stretching or compressing the third spring 512 and generating elastic force. The third spring 512 can drive the U-shaped frame 508 to reset, thereby achieving the effect of driving the second filter plate 302 to vibrate reciprocatingly, so as to completely shake off the dust or impurities attached to the second filter plate 302, thereby achieving the effect of cleaning. This embodiment does not require manual cleaning by staff.

[0064] For further information, see Figure 6When the first gear 5 loses meshing with the first rack 604, in order to prevent the first gear 5 from self-rotating, in this embodiment, the end of the sleeve 501 away from the first gear 5 is slidably plugged and arranged with a telescopic rod 503, and a plurality of groups of strip-shaped card slots 502 are arranged in a circumferential array on the inner wall of the sleeve 501, and a strip card seat 504 corresponding to and slidingly engaged with the strip card slots 502 is fixedly arranged on the telescopic rod 503, and the end of the telescopic rod 503 away from the sleeve 501 is fixed with a screw 505, wherein the positioning frame 5 07 A baffle plate 506 spirally connected to the screw rod 505 is fixedly arranged on one side; it can be explained that in this embodiment, by setting the baffle plate 506 and the screw rod 505, a certain torsional force is required for the rotation between the screw rod 505 and the baffle plate 506. Therefore, in this embodiment, the first gear 5 can only be driven to rotate when it is engaged with the first rack 604. When the two are separated, the screw rod 505 always maintains a stable state, thereby driving the sleeve 501 and the second filter plate 302 to be in a stable state.

[0065] See also Figure 3-Figure 4 , when the rectifier cabinet body 1 is in a state of normal heat dissipation, in order to allow the air input by the first heat dissipation module 3 and the second heat dissipation module 4 to stably flow to the rectifier cabinet body 1, in this embodiment, air guide plates 209 are symmetrically fixedly arranged on both sides of the heat dissipation cabinet 2, and the air guide plates 209 and the side walls of the heat dissipation cabinet 2 are enclosed to form an air guide channel 211, and the air guide channel 211 extends to the opening 204, wherein an air groove 212 is provided at a position corresponding to the heat dissipation port 210 on the air guide plate 209, and a sealing disk 208 is embedded on the side of the air groove 212 away from the heat dissipation port 210, wherein the sealing disks 208 on both sides are connected to a pushing portion that drives them to approach toward each other or move away from each other; it can be explained that when the rectifier cabinet body 1 is in a normal heat dissipation state, the sealing disk 208 is in a state of sealing the air groove 212, and at this time, the adjustment module also adjusts the opening 204 to be in an open state, and the outside air can first enter the air guide channel 211 from the heat dissipation port 210, and then be transported to the rectifier cabinet body 1 (see Fig.10 ), accordingly, when the adjustment module adjusts the opening 204 to be closed, the pusher drives the sealing disks 208 on both sides to approach each other, so that the air slots 212 are in an open state, and then the air entering the air guide channel 211 from the heat dissipation port 210 on one side can first enter the heat dissipation cabinet 2 through the air slots 212, and then be discharged from the air slots 212 and the heat dissipation port 210 on the other side in sequence (see Fig.11 ), so as to purify the air in the heat dissipation cabinet 2.

[0066] For details, please refer to Figure 3-Figure 4 as well as Fig. 9The adjustment module includes a first windshield 205 symmetrically slidably arranged at the opening 204, a second windshield 206 is slidably arranged on one side of the first windshields 205 on both sides away from each other, and a reserved opening 207 for communicating with the wind guide channel 211 is formed between the first windshield 205 and the second windshield 206. A support tube 703 is fixedly arranged on the top of the first windshield 205, and a telescopic shaft 704 slidably plugged with the support tube 703 is fixedly arranged on the second windshield 206. A fourth spring 705 is arranged on the telescopic shaft 704, one end of the fourth spring 705 is fixed to the support tube 703, and the other end is fixed to the top of the second windshield 206. A servo motor 7 is fixedly arranged on the top of the heat dissipation cabinet 2, and the output end of the servo motor 7 is meshed with the second gear 702. The two sides of the second gear 702 are respectively connected with the second racks slidably arranged on the heat dissipation cabinet 2 701 are meshed with each other, and the second racks 701 on both sides are arranged in parallel and staggered manner. The ends of the second racks 701 on both sides that are away from each other are fixed to the second wind shield 206 by connecting rods, wherein the first wind shield 205 is fixed to the sealing disk 208 by connecting rods; it can be explained that when the opening 204 needs to be closed, the servo motor 7 is started to drive the second gear 702 to rotate, and the second gear 702 can drive the second wind shields 206 on both sides and the first wind shield 205 to move towards each other by meshing with the second racks 701 on both sides. When the first wind shields 205 on both sides are in contact, as the second wind shields 206 on both sides continue to move, the reserved opening 207 can be closed, and the opening 204 is also closed at this time. Correspondingly, when the servo motor 7 rotates in the opposite direction, the various components are also reset synchronously, and normal wind guidance and heat dissipation can be performed.

[0067] It should also be noted that when the first wind shield plates 205 on both sides are close to each other, the first wind shield plates 205 can synchronously drive the sealing disk 208 to move, thereby opening the wind slot 212. This embodiment does not require the provision of other servo drive devices to adjust the movement of the sealing disk 208. This embodiment can open the wind slot 212 while closing the opening 204, and has higher stability and synchronization.

[0068] Also, see Figure 2-Figure 3 Dust collecting boxes 202 are fixedly arranged on both sides of the bottom of the heat dissipation cabinet 2 to collect dust falling from the second filter plate 302.

[0069] See also Figure 4 A serpentine heat exchange tube 303 is also arranged on one side of the fan 304. The serpentine heat exchange tube 303 is connected to the outer water cooling mechanism through a pipeline. When dissipating heat, the serpentine heat exchange tube 303 can further reduce the air temperature input into the heat dissipation cabinet 2, thereby improving the heat dissipation effect.

[0070] A heat dissipation method for a rectifier cabinet heat dissipation structure comprises the following steps:

[0071] See also Figure 1-Figure 4 , S1, when the rectifier cabinet body 1 is cooled, the outside air is input into the cooling cabinet 2 through the first cooling module 3 and the second cooling module 4 respectively, and the air is transported to the rectifier cabinet body 1 through the opening 204;

[0072] S2. When the electric power worker needs to enter the rectifier cabinet body 1, before opening the cabinet door 201, the opening 204 is adjusted to be in a closed state by adjusting the module to separate the rectifier cabinet body 1 from the heat dissipation cabinet 2;

[0073] S3, open the cabinet door 201, the power construction personnel wear dust-proof clothing and anti-static clothing to enter the heat dissipation cabinet 2 and close the cabinet door 201;

[0074] S4, turn off the fan 304 on one side and turn on the fan 304 on the other side. The turned-on fan 304 draws outside air into the heat dissipation cabinet 2 through the heat dissipation port 210 on one side, and the air entering the heat dissipation cabinet 2 can be discharged through the heat dissipation port 210 on this side, which lasts for a period of time;

[0075] S5. When the air passes through the heat dissipation port 210 and the heat dissipation box 301, the dust impurities in the air are removed by the dust removal module arranged in the heat dissipation box 301;

[0076] S6. After the cleaning is completed, the opening 204 is finally opened by adjusting the module, and the power staff can enter the rectifier cabinet body 1 to operate.

[0077] A rectifier cabinet includes a rectifier cabinet heat dissipation structure as in Examples 1-2, and also includes a plurality of groups of air outlets 101 arranged on a rectifier cabinet body 1, and a third filter plate 102 is fixedly embedded in the air outlet 101; specifically, in this embodiment, the number of air outlets 101 is not limited, and can be set accordingly based on the size of the rectifier cabinet body 1 to meet actual ventilation requirements.

[0078] The air outlet 101 may be disposed on the top or side of the rectifier cabinet body 1 , and its specific location is not limited.

[0079] It should be noted that the air input into the rectifier cabinet body 1 by the heat dissipation cabinet 2 can finally be discharged through the air outlet 101. A third filter plate is arranged at the air outlet 101 to prevent dust in the external air from entering the rectifier cabinet body 1 through the air outlet 101, thereby achieving a better dust prevention effect.
