Description

Technical Field

[0001] This invention relates to the field of power supply cabinet technology, and in particular to a high-frequency DC switching power supply cabinet with an integrated structure for uniform heat distribution. Background Technology

[0002] An integrated power supply is a complete set of power equipment that uses a DC power supply as its core, combining AC uninterruptible power supplies (UPS), power inverters (INV), and DC / DC converters (DC / DC) into a single unit, sharing a common DC power source. It has wide applications in industry, scientific research, and power equipment fields. The integrated power supply cabinet contains numerous electrical components, which generate a significant amount of heat during operation. If heat cannot be dissipated in a timely manner, it can easily affect the operation of these components, or even cause damage or accidents.

[0003] The most common cooling method used in existing technologies is air cooling, which usually involves installing diffused fans on one side or top of the cabinet for heat dissipation. However, the following problems still exist in the process of heat dissipation for the cabinet:

[0004] In existing technologies, when cooling cabinets, fans on one side or top of the cabinet can only cool the center area and cannot cool the interior evenly. Heat in the dead corners inside the cabinet cannot be dissipated, which can damage components.

[0005] In the existing technology, components are mounted on the back panel or tray of the cabinet, which prevents heat dissipation at the contact point between the components and the back panel or tray, leading to component damage over time.

[0006] To address the aforementioned issues, this invention proposes a high-frequency DC switching power supply cabinet with an integrated structure for uniform heat distribution. Summary of the Invention

[0007] This invention provides a high-frequency DC switching power supply cabinet with an integrated structure for uniform heat distribution, which solves the shortcomings of the prior art where the fan can only dissipate heat at the center position, and the contact position between the device and the back plate or support plate cannot dissipate heat.

[0008] This invention provides the following technical solution:

[0009] A high-frequency DC switching power supply cabinet with an integrated structure for uniform heat distribution includes: a cabinet, wherein the cabinet is provided with a power distribution compartment, a first air inlet compartment and a second air inlet compartment, and the first air inlet compartment and the second air inlet compartment are located on both sides of the power distribution compartment, and multiple trays are fixedly connected from top to bottom in the power distribution compartment;

[0010] Multiple fixing structures are set inside the tray to fix the components and create a gap between the components and the tray, which facilitates heat dissipation of the components later.

[0011] A uniform heat dissipation structure is installed in the first air intake chamber to dissipate heat evenly and without dead corners in the power distribution chamber.

[0012] An accelerated heat dissipation structure is installed inside the second air intake chamber to further dissipate heat from the power distribution chamber.

[0013] In one possible design, the fixing structure includes a storage slot and a wire-passing hole disposed within the tray. A bracket for placing components is provided above the storage slot. A bidirectional threaded rod is rotatably connected within the storage slot, with one end of the bidirectional threaded rod passing through the wire-passing hole and extending to one side of the tray. Two nut blocks are threadedly fitted onto the outer wall of the bidirectional threaded rod, slidably connected to the inner wall of the bottom of the storage slot, with the two nut blocks located on the positive and negative thread sections of the bidirectional threaded rod, respectively. Two first connecting rods are rotatably connected to both sides of the bottom of the bracket, with the bottom ends of the two first connecting rods on the same side rotatably connected to the top of the corresponding nut blocks. Multiple clamping plates are slidably fitted onto the outer walls of both sides of the bracket, with the multiple clamping plates on the same side... The storage slot is fixedly connected to a connecting rod, and a fixing block is fixedly connected to the bottom inner wall. Two second connecting rods are rotatably connected to the top of the fixing block, and the top of the second connecting rod is rotatably connected to the connecting rod. Rotating the bidirectional threaded rod causes the two nut blocks to move towards the middle. The nut blocks can lift the bracket upward through the rotation of the first connecting rod, so that there is a large gap between the components and the bracket, which facilitates the heat dissipation of the components in the later stage. When the bracket moves upward, multiple clamping plates move towards the middle through the action of the connecting rod and the second connecting rod. Then, the multiple clamping plates on both sides of the bracket clamp the components on the top of the bracket, which not only facilitates the heat dissipation of the components, but also easily fixes the components.

[0014] In one possible design, the uniform heat dissipation structure includes a reciprocating lead screw rotatably connected within a first air intake chamber. A drive motor is fixedly connected inside the enclosure. The output shaft of the drive motor extends into the first air intake chamber and is fixedly connected to the reciprocating lead screw. A sliding block, threadedly connected to the reciprocating lead screw, is slidably connected to the inner wall of the first air intake chamber on the side near the power distribution chamber. Multiple first exhaust pipes are slidably connected within the power distribution chamber. Multiple first through holes communicating with the power distribution chamber are provided on the inner wall of the first air intake chamber on the side near the power distribution chamber. The same first connecting pipe is slidably connected within each of the multiple first through holes, and the first connecting pipe penetrates through the first exhaust pipe. A through hole is connected to multiple first exhaust pipes. A sliding block is fixedly sleeved on the outer wall of the first connecting pipe. A first connecting hose is fixedly connected to the bottom of the first connecting pipe. When the drive motor is started, the reciprocating screw is driven to rotate. The reciprocating screw drives the sliding block and the first connecting pipe to slide back and forth in the first air intake chamber. The first connecting pipe drives multiple first exhaust pipes to slide back and forth along the first through hole. The cold air in the first connecting pipe is discharged into the power distribution chamber through the through holes above and below the first exhaust pipes. This can evenly cool the inside of the power distribution chamber. The gap between the components and the support plate facilitates the cold air to quickly carry away the heat of the components.

[0015] In one possible design, the accelerated heat dissipation structure includes a second through hole disposed on the inner wall of one side of the second air intake chamber, and the second through hole is connected to the power distribution chamber. Multiple second exhaust pipes are slidably connected from top to bottom inside the power distribution chamber. A single second connecting pipe is slidably connected inside the second through hole, and the second connecting pipe is connected to the multiple second exhaust pipes. A rotating rod is rotatably connected to the inner wall of the second air intake chamber on the side near the power distribution chamber, and one end of the rotating rod is slidably engaged with the second connecting pipe. A third through hole is provided on the inner wall of the second air intake chamber on the side near the power distribution chamber, and is connected to the power distribution chamber. The sliding connection has a protrusion that slides with the other end of the rotating rod, and one end of the protrusion extends into the power distribution compartment and is fixedly connected to one of the first exhaust pipes. A second connecting hose is fixedly connected to one side of the second connecting pipe. When the first exhaust pipe moves back and forth, the sliding engagement between the protrusion and the rotating rod can cause the rotating rod to rotate back and forth. The sliding engagement between the rotating rod and the second connecting pipe can cause the second connecting pipe to drive the second exhaust pipe to slide back and forth along the second through hole. The alternating back and forth movement of the first exhaust pipe and the second exhaust pipe can effectively and quickly cool down the power distribution compartment from all directions.

[0016] In one possible design, the inner walls of the first and second air intake chambers on the side away from the power distribution chamber are provided with multiple air inlets. Multiple arc-shaped rain shields for rain protection of the air inlets are fixedly connected to both sides of the cabinet. The first air intake fan and the second air intake fan are respectively provided on both sides of the cabinet. Multiple ventilation fans are provided on the top inner wall of the power distribution chamber.

[0017] In one possible design, a sliding rod is fixedly connected inside the storage slot, and two sliders are slidably sleeved on the outer wall of the sliding rod. The bottom ends of the other two first connecting rods are rotatably connected to the tops of the two sliders respectively. The nut block is fixedly connected to the sliders through a fixing rod. The nut block drives the sliders to move through the fixing rod. The sliders also lift the bracket through the first connecting rod at their top. Thus, the sliders and the first connecting rod at their top can play a balancing role on the bracket.

[0018] In one possible design, a V-shaped plate located above the first air intake fan is fixedly connected inside the first air intake chamber, and the bottom end of the first connecting hose passes through the V-shaped plate. The inner wall of the first air intake chamber on the side away from the power distribution chamber is provided with multiple drainage holes, and the drainage holes correspond to the inclined surface of the V-shaped plate. When the first air intake fan draws cold air from the outside into the first air intake chamber, the V-shaped plate can concentrate the cold air into the first connecting hose, which facilitates the first exhaust pipe to cool the power distribution chamber. During the rainy season, rainwater falls onto the V-shaped plate through the air intake and can be discharged through the drainage holes.

[0019] In one possible design, an inverted V-shaped plate is fixedly connected inside the second air intake chamber, located below the second air intake fan. A U-shaped tube is fixedly inserted through the bottom end of the inverted V-shaped plate, and the other end of the U-shaped tube is connected to a second connecting hose. A drain pipe extending to the side of the cabinet is fixedly connected to one side of the U-shaped tube. When the second air intake fan draws cold air from the outside into the second air intake chamber, the inverted V-shaped plate can concentrate the cold air into the second connecting hose, facilitating the cooling of the electrical distribution chamber by the second exhaust pipe. In addition, when rainwater falls on the inverted V-shaped plate through the second air intake fan, the rainwater accumulates at the bottom of the U-shaped tube through the inverted V-shaped plate, and the accumulated rainwater is discharged to the outside through the drain pipe.

[0020] In one possible design, the top and bottom of both the first and second exhaust pipes are provided with multiple through holes, and the second exhaust pipe and the first exhaust pipe are arranged alternately. The alternating reciprocating movement of the first and second exhaust pipes can effectively and quickly cool down the power distribution compartment from all directions. Furthermore, the alternating arrangement of the first and second exhaust pipes can prevent the airflows from the first and second exhaust pipes from colliding and canceling each other out when the first and second exhaust pipes exhaust air above and below the tray, thus avoiding affecting the heat dissipation efficiency.

[0021] In one possible design, the top of the cabinet is rotatably connected to a bidirectional screw via a base. A rotating motor is fixedly connected to the top of the cabinet, and the output shaft of the rotating motor is fixedly connected to the bidirectional screw. Two brackets are slidably connected to the top of the cabinet and threaded to the bidirectional screw, with the two brackets located on the positive and negative thread sections of the bidirectional screw, respectively. A first rain shield and a second rain shield are fixedly connected to the top of the two brackets, with the top of the second rain shield touching the bottom inner wall of the first rain shield. The contact between the first and second rain shields not only prevents rainwater from entering the ventilator fan but also does not hinder the ventilator fan from expelling hot air from the power distribution compartment to the outside. On sunny days, the first and second rain shields are opened, exposing the ventilator fan. The hot air expelled by the ventilator fan, no longer shielded by the first and second rain shields, can accelerate the dissipation of hot air.

[0022] It should be understood that the above general description and the following detailed description are merely exemplary and do not limit the invention.

[0023] In this invention, a bidirectional threaded rod is rotatably connected inside the storage slot. Two nut blocks are threadedly fitted on the outer wall of the bidirectional threaded rod. Two first connecting rods are rotatably connected to both sides of the bottom of the bracket. The bottom end of the first connecting rod is rotatably connected to the top of the nut block. Multiple clamping plates are slidably fitted on both sides of the outer wall of the bracket. Two second connecting rods are rotatably connected to the top of the fixing block, and the second connecting rods are rotatably connected to the connecting rod. The two nut blocks move towards the middle, and the bracket can be lifted upward by the first connecting rods. The multiple clamping plates move towards the middle by the action of the connecting rods and the second connecting rods. Thus, the multiple clamping plates on both sides of the bracket clamp the components on the top of the bracket, so that there is a large gap between the components and the bracket. This not only facilitates the heat dissipation of the components but also makes it easy to fix the components.

[0024] In this invention, a sliding block is slidably connected to the inner wall of the first air intake chamber near the power distribution chamber and threadedly connected to the reciprocating screw. Multiple first exhaust pipes are slidably connected inside the power distribution chamber, and the same first connecting pipe is slidably connected inside the multiple first through holes. The first connecting pipe is connected to the multiple first exhaust pipes. The reciprocating screw drives the sliding block and the first connecting pipe to slide back and forth inside the first air intake chamber. The first connecting pipe drives the multiple first exhaust pipes to slide back and forth along the first through holes. The cold air in the first connecting pipe is discharged into the power distribution chamber through the through holes above and below the first exhaust pipe, which can uniformly cool the inside of the power distribution chamber. The gap between the components and the support plate facilitates the cold air to quickly carry away the heat of the components.

[0025] In this invention, multiple second exhaust pipes are slidably connected from top to bottom inside the power distribution compartment. A second connecting pipe is slidably connected inside the second through hole, and the second connecting pipe is connected to multiple second exhaust pipes. A rotating rod is rotatably connected to one side inner wall of the second air intake compartment, and one end of the rotating rod is slidably engaged with the second connecting pipe. A protrusion is slidably connected inside the third through hole and is slidably engaged with the other end of the rotating rod. The protrusion is fixedly connected to one of the first exhaust pipes. When the first exhaust pipe moves back and forth, the sliding engagement between the protrusion and the rotating rod enables the rotating rod to rotate back and forth. The sliding engagement between the rotating rod and the second connecting pipe enables the second connecting pipe to drive the second exhaust pipe to slide back and forth along the second through hole. The alternating back and forth movement of the first exhaust pipe and the second exhaust pipe can effectively and quickly cool down the power distribution compartment from all directions.

[0026] In this invention, an inverted V-plate located below the second air intake fan is fixedly connected inside the second air intake chamber. A U-shaped tube is fixedly inserted through the bottom end of the inverted V-plate, and the other end of the U-shaped tube is connected to a second connecting hose. A drain pipe extending to the side of the cabinet is fixedly connected to one side of the U-shaped tube. When the second air intake fan draws cold air from the outside into the second air intake chamber, the inverted V-plate can concentrate the cold air into the second connecting hose, which facilitates the second exhaust pipe to cool the electrical distribution chamber. In addition, when rainwater falls on the inverted V-plate through the second air intake fan, the rainwater accumulates at the bottom of the U-shaped tube through the inverted V-plate. At this time, the accumulated rainwater is discharged to the outside through the drain pipe.

[0027] In this invention, the alternating reciprocating movement of the first and second exhaust pipes can effectively and quickly cool down the power distribution compartment in all directions. Furthermore, the fixed structure can easily clamp the components on the top of the bracket, which not only creates a gap between the components and the bracket to facilitate heat dissipation but also easily fixes the components.

[0046] Example 1

[0047] Reference Figure 1 , Figure 2 and Figure 6 This embodiment of a high-frequency DC switching power supply cabinet with an integrated heat distribution structure includes: a cabinet 1, which contains a power distribution compartment 2, a first air intake compartment 3, and a second air intake compartment 4. The first air intake compartment 3 and the second air intake compartment 4 are located on both sides of the power distribution compartment 2. Multiple support plates 5 are fixedly connected from top to bottom in the power distribution compartment 2 by bolts. Multiple sets of fixing structures are respectively set in the support plates 5 to fix the components and to create gaps between the components and the support plates 5, which facilitates heat dissipation of the components later. A uniform heat dissipation structure is set in the first air intake compartment 3 to dissipate heat evenly and without dead corners in the power distribution compartment 2. An accelerated heat dissipation structure is set in the second air intake compartment 4 to further dissipate heat in the power distribution compartment 2.

[0048] Reference Figure 2 The inner walls of the first air intake chamber 3 and the second air intake chamber 4, which are away from the power distribution chamber 2, are provided with multiple air inlets 35. Both sides of the cabinet 1 are fixedly connected with multiple arc-shaped rain shields 36 for rain protection of the air inlets 35 by bolts. The cabinet 1 is provided with a first air intake fan 19 and a second air intake fan 39 on both sides respectively. The inner wall of the top of the power distribution chamber 2 is provided with multiple ventilation fans 38.

[0049] Reference Figure 3 , Figure 4 and Figure 5The fixing structure includes a storage groove 6 and a wire hole 7 set in the tray 5. A bracket 8 for placing components is provided above the storage groove 6. A bidirectional threaded rod 9 is rotatably connected inside the storage groove 6, with one end of the bidirectional threaded rod 9 passing through the wire hole 7 and extending to one side of the tray 5. Two nut blocks 11 are threadedly fitted on the outer wall of the bidirectional threaded rod 9 and slidably connected to the inner wall of the bottom of the storage groove 6. The two nut blocks 11 are located on the positive and negative thread sections of the bidirectional threaded rod 9, respectively. Two first connecting rods 13 are rotatably connected to both sides of the bottom of the bracket 8. The bottom ends of the two first connecting rods 13 on the same side are rotatably connected to the top of the corresponding nut blocks 11. Multiple clamping plates 15 are slidably fitted on both outer walls of the bracket 8. The multiple clamping plates 15 on the same side are fixedly connected by connecting rods 16. A fixing block 17 is fixedly connected to the bottom inner wall of the groove 6 by bolts. Two second connecting rods 18 are rotatably connected to the top of the fixing block 17, and the top of the second connecting rod 18 is rotatably connected to the connecting rod 16. Rotating the double-threaded rod 9 causes the two nut blocks 11 to move towards the middle. The nut blocks 11 can lift the bracket 8 upward through the rotation of the first connecting rod 13, so that there is a large gap between the components and the tray 5, which facilitates the heat dissipation in the later stage. The air can carry away the heat through the gap. When the bracket 8 moves upward, multiple clamping plates 15 move towards the middle through the action of the connecting rod 16 and the second connecting rod 18. Then, the multiple clamping plates 15 on both sides of the bracket 8 clamp the components on the top of the bracket 8, which not only facilitates the heat dissipation of the components, but also easily completes the fixation of the components.

[0050] Reference Figure 5 A sliding rod 10 is fixedly connected to the storage slot 6 by bolts. Two sliders 12 are slidably sleeved on the outer wall of the sliding rod 10. The bottom ends of the other two first connecting rods 13 are rotatably connected to the top of the two sliders 12 respectively. The nut block 11 is fixedly connected to the slider 12 by a fixing rod 14. The nut block 11 drives the slider 12 to move through the fixing rod 14. The slider 12 also lifts the bracket 8 through the first connecting rod 13 at its top. Thus, the slider 12 and the first connecting rod 13 at its top can play a balancing role for the bracket 8.

[0051] Reference Figure 7 and Figure 9The uniform heat dissipation structure includes a reciprocating lead screw 24 rotatably connected inside the first air intake chamber 3. A drive motor 25 is bolted to the cabinet 1. The output shaft of the drive motor 25 extends into the first air intake chamber 3 and is fixedly connected to the reciprocating lead screw 24 via a coupling. A sliding block 23, threadedly connected to the reciprocating lead screw 24, is slidably connected to the inner wall of the first air intake chamber 3 near the power distribution chamber 2. Multiple first exhaust pipes 21 are slidably connected inside the power distribution chamber 2. Multiple first through holes 40 communicating with the power distribution chamber 2 are provided on the inner wall of the first air intake chamber 3 near the power distribution chamber 2. The same first connecting pipe 22 is slidably connected to the multiple first through holes 40, and the first connecting pipe 22 passes through the first through holes 40 and communicates with multiple first connecting pipes 21. The first exhaust pipes 21 are connected together. The sliding block 23 is fixedly sleeved on the outer wall of the first connecting pipe 22. The bottom of the first connecting pipe 22 is fixedly connected to the first connecting hose 26. The drive motor 25 is started to drive the reciprocating screw 24 to rotate. The reciprocating screw 24 drives the sliding block 23 and the first connecting pipe 22 to slide back and forth in the first air intake chamber 3. The first connecting pipe 22 drives the multiple first exhaust pipes 21 to slide back and forth along the first through hole 40. The cold air in the first connecting pipe 22 is discharged into the power distribution chamber 2 through the through holes above and below the first exhaust pipe 21. It can evenly cool the inside of the power distribution chamber 2. The gap between the components and the support plate 5 makes it easy for the cold air to quickly carry away the heat of the components.

[0052] Reference Figure 8 and Figure 9 The accelerated heat dissipation structure includes a second through hole 41 on the inner wall of one side of the second air intake chamber 4, which is connected to the power distribution chamber 2. Multiple second exhaust pipes 27 are slidably connected from top to bottom inside the power distribution chamber 2. A second connecting pipe 28 is slidably connected inside the second through hole 41, and the second connecting pipe 28 is connected to the multiple second exhaust pipes 27. A rotating rod 29 is rotatably connected to the inner wall of the second air intake chamber 4 near the power distribution chamber 2, and one end of the rotating rod 29 is slidably engaged with the second connecting pipe 28. A third through hole 42 is provided on the inner wall of the second air intake chamber 4 near the power distribution chamber 2, which is connected to the power distribution chamber 2. A third through hole 42 is slidably connected to the rotating rod 29. A convex post 30 with one end slidingly engaged extends into the power distribution compartment 2 and is fixedly connected to one of the first exhaust pipes 21. A second connecting hose 33 is fixedly connected to one side of the second connecting pipe 28. When the first exhaust pipe 21 moves back and forth, the sliding engagement between the convex post 30 and the rotating rod 29 enables the rotating rod 29 to rotate back and forth. The sliding engagement between the rotating rod 29 and the second connecting pipe 28 enables the second connecting pipe 28 to drive the second exhaust pipe 27 to slide back and forth along the second through hole 41. The alternating back and forth movement of the first exhaust pipe 21 and the second exhaust pipe 27 can effectively and quickly cool down the power distribution compartment 2 from all directions.

[0053] Reference Figure 2 andFigure 7 A V-shaped plate 20 located above the first intake fan 19 is fixedly connected to the first intake chamber 3 by bolts, and the bottom end of the first connecting hose 26 passes through the V-shaped plate 20. The inner wall of the first intake chamber 3 away from the power distribution chamber 2 is provided with multiple drainage holes 37, and the drainage holes 37 correspond to the inclined surface of the V-shaped plate 20. When the first intake fan 19 draws cold air from the outside into the first intake chamber 3, the V-shaped plate 20 can concentrate the cold air into the first connecting hose 26, which facilitates the first exhaust pipe 21 to cool the power distribution chamber 2. During the rainy season, rainwater falls on the V-shaped plate 20 through the air inlet 35 and can be discharged through the drainage holes 37.

[0054] Reference Figure 9 and Figure 10 Inside the second air intake chamber 4, an inverted V-shaped plate 31 located below the second air intake fan 39 is fixedly connected by bolts. A U-shaped tube 32 is fixedly inserted through the bottom end of the inverted V-shaped plate 31. The other end of the U-shaped tube 32 is connected to the second connecting hose 33. A drain pipe 34 extending to the side of the cabinet 1 is fixedly connected to one side of the U-shaped tube 32. When the second air intake fan 39 draws cold air from the outside into the second air intake chamber 4, the inverted V-shaped plate 31 can concentrate the cold air into the second connecting hose 33, which facilitates the second exhaust pipe 27 to cool the electrical distribution chamber 2. In addition, when rainwater falls on the inverted V-shaped plate 31 through the second air intake fan 39, the rainwater accumulates at the bottom of the U-shaped tube 32 through the inverted V-shaped plate 31. At this time, the accumulated rainwater is discharged to the outside through the drain pipe 34.

[0055] Reference Figure 6 The first exhaust pipe 21 and the second exhaust pipe 27 are provided with multiple through holes at the top and bottom. The second exhaust pipe 27 and the first exhaust pipe 21 are arranged alternately. The alternating reciprocating movement of the first exhaust pipe 21 and the second exhaust pipe 27 can effectively and quickly cool down the power distribution compartment 2 from all directions. The alternating arrangement of the first exhaust pipe 21 and the second exhaust pipe 27 can prevent the airflows discharged by the first exhaust pipe 21 and the second exhaust pipe 27 from colliding and canceling each other when exhausting above and below the support plate 5, thus affecting the heat dissipation efficiency.

[0056] Example 2

[0057] Reference Figure 1 , Figure 2 and Figure 6This embodiment of a high-frequency DC switching power supply cabinet with an integrated heat distribution structure includes: a cabinet 1, which contains a power distribution compartment 2, a first air intake compartment 3, and a second air intake compartment 4. The first air intake compartment 3 and the second air intake compartment 4 are located on both sides of the power distribution compartment 2. Multiple support plates 5 are fixedly connected from top to bottom in the power distribution compartment 2 by bolts. Multiple sets of fixing structures are respectively set in the support plates 5 to fix the components and to create gaps between the components and the support plates 5, which facilitates heat dissipation of the components later. A uniform heat dissipation structure is set in the first air intake compartment 3 to dissipate heat evenly and without dead corners in the power distribution compartment 2. An accelerated heat dissipation structure is set in the second air intake compartment 4 to further dissipate heat in the power distribution compartment 2.

[0058] Reference Figure 2 The inner walls of the first air intake chamber 3 and the second air intake chamber 4, which are away from the power distribution chamber 2, are provided with multiple air inlets 35. Both sides of the cabinet 1 are fixedly connected with multiple arc-shaped rain shields 36 for rain protection of the air inlets 35 by bolts. The cabinet 1 is provided with a first air intake fan 19 and a second air intake fan 39 on both sides respectively. The inner wall of the top of the power distribution chamber 2 is provided with multiple ventilation fans 38.

[0059] Reference Figure 3 , Figure 4 and Figure 5 The fixing structure includes a storage groove 6 and a wire hole 7 set in the tray 5. A bracket 8 for placing components is provided above the storage groove 6. A bidirectional threaded rod 9 is rotatably connected inside the storage groove 6, with one end of the bidirectional threaded rod 9 passing through the wire hole 7 and extending to one side of the tray 5. Two nut blocks 11 are threadedly fitted on the outer wall of the bidirectional threaded rod 9 and slidably connected to the inner wall of the bottom of the storage groove 6. The two nut blocks 11 are located on the positive and negative thread sections of the bidirectional threaded rod 9, respectively. Two first connecting rods 13 are rotatably connected to both sides of the bottom of the bracket 8. The bottom ends of the two first connecting rods 13 on the same side are rotatably connected to the top of the corresponding nut blocks 11. Multiple clamping plates 15 are slidably fitted on both outer walls of the bracket 8. The multiple clamping plates 15 on the same side are fixedly connected by connecting rods 16. A fixing block 17 is fixedly connected to the bottom inner wall of the groove 6 by bolts. Two second connecting rods 18 are rotatably connected to the top of the fixing block 17, and the top of the second connecting rod 18 is rotatably connected to the connecting rod 16. Rotating the double-threaded rod 9 causes the two nut blocks 11 to move towards the middle. The nut blocks 11 can lift the bracket 8 upward through the rotation of the first connecting rod 13, so that there is a large gap between the components and the tray 5, which facilitates the heat dissipation in the later stage. The air can carry away the heat through the gap. When the bracket 8 moves upward, multiple clamping plates 15 move towards the middle through the action of the connecting rod 16 and the second connecting rod 18. Then, the multiple clamping plates 15 on both sides of the bracket 8 clamp the components on the top of the bracket 8, which not only facilitates the heat dissipation of the components, but also easily completes the fixation of the components.

[0060] Reference Figure 5 A sliding rod 10 is fixedly connected to the storage slot 6 by bolts. Two sliders 12 are slidably sleeved on the outer wall of the sliding rod 10. The bottom ends of the other two first connecting rods 13 are rotatably connected to the top of the two sliders 12 respectively. The nut block 11 is fixedly connected to the slider 12 by a fixing rod 14. The nut block 11 drives the slider 12 to move through the fixing rod 14. The slider 12 also lifts the bracket 8 through the first connecting rod 13 at its top. Thus, the slider 12 and the first connecting rod 13 at its top can play a balancing role for the bracket 8.

[0061] Reference Figure 7 and Figure 9 The uniform heat dissipation structure includes a reciprocating lead screw 24 rotatably connected inside the first air intake chamber 3. A drive motor 25 is bolted to the cabinet 1. The output shaft of the drive motor 25 extends into the first air intake chamber 3 and is fixedly connected to the reciprocating lead screw 24 via a coupling. A sliding block 23, threadedly connected to the reciprocating lead screw 24, is slidably connected to the inner wall of the first air intake chamber 3 near the power distribution chamber 2. Multiple first exhaust pipes 21 are slidably connected inside the power distribution chamber 2. Multiple first through holes 40 communicating with the power distribution chamber 2 are provided on the inner wall of the first air intake chamber 3 near the power distribution chamber 2. The same first connecting pipe 22 is slidably connected to the multiple first through holes 40, and the first connecting pipe 22 passes through the first through holes 40 and communicates with multiple first connecting pipes 21. The first exhaust pipes 21 are connected together. The sliding block 23 is fixedly sleeved on the outer wall of the first connecting pipe 22. The bottom of the first connecting pipe 22 is fixedly connected to the first connecting hose 26. The drive motor 25 is started to drive the reciprocating screw 24 to rotate. The reciprocating screw 24 drives the sliding block 23 and the first connecting pipe 22 to slide back and forth in the first air intake chamber 3. The first connecting pipe 22 drives the multiple first exhaust pipes 21 to slide back and forth along the first through hole 40. The cold air in the first connecting pipe 22 is discharged into the power distribution chamber 2 through the through holes above and below the first exhaust pipe 21. It can evenly cool the inside of the power distribution chamber 2. The gap between the components and the support plate 5 makes it easy for the cold air to quickly carry away the heat of the components.

[0062] Reference Figure 8 and Figure 9The accelerated heat dissipation structure includes a second through hole 41 on the inner wall of one side of the second air intake chamber 4, which is connected to the power distribution chamber 2. Multiple second exhaust pipes 27 are slidably connected from top to bottom inside the power distribution chamber 2. A second connecting pipe 28 is slidably connected inside the second through hole 41, and the second connecting pipe 28 is connected to the multiple second exhaust pipes 27. A rotating rod 29 is rotatably connected to the inner wall of the second air intake chamber 4 near the power distribution chamber 2, and one end of the rotating rod 29 is slidably engaged with the second connecting pipe 28. A third through hole 42 is provided on the inner wall of the second air intake chamber 4 near the power distribution chamber 2, which is connected to the power distribution chamber 2. A third through hole 42 is slidably connected to the rotating rod 29. A convex post 30 with one end slidingly engaged extends into the power distribution compartment 2 and is fixedly connected to one of the first exhaust pipes 21. A second connecting hose 33 is fixedly connected to one side of the second connecting pipe 28. When the first exhaust pipe 21 moves back and forth, the sliding engagement between the convex post 30 and the rotating rod 29 enables the rotating rod 29 to rotate back and forth. The sliding engagement between the rotating rod 29 and the second connecting pipe 28 enables the second connecting pipe 28 to drive the second exhaust pipe 27 to slide back and forth along the second through hole 41. The alternating back and forth movement of the first exhaust pipe 21 and the second exhaust pipe 27 can effectively and quickly cool down the power distribution compartment 2 from all directions.

[0063] Reference Figure 2 and Figure 7 A V-shaped plate 20 located above the first intake fan 19 is fixedly connected to the first intake chamber 3 by bolts, and the bottom end of the first connecting hose 26 passes through the V-shaped plate 20. The inner wall of the first intake chamber 3 away from the power distribution chamber 2 is provided with multiple drainage holes 37, and the drainage holes 37 correspond to the inclined surface of the V-shaped plate 20. When the first intake fan 19 draws cold air from the outside into the first intake chamber 3, the V-shaped plate 20 can concentrate the cold air into the first connecting hose 26, which facilitates the first exhaust pipe 21 to cool the power distribution chamber 2. During the rainy season, rainwater falls on the V-shaped plate 20 through the air inlet 35 and can be discharged through the drainage holes 37.

[0064] Reference Figure 9 and Figure 10 Inside the second air intake chamber 4, an inverted V-shaped plate 31 located below the second air intake fan 39 is fixedly connected by bolts. A U-shaped tube 32 is fixedly inserted through the bottom end of the inverted V-shaped plate 31. The other end of the U-shaped tube 32 is connected to the second connecting hose 33. A drain pipe 34 extending to the side of the cabinet 1 is fixedly connected to one side of the U-shaped tube 32. When the second air intake fan 39 draws cold air from the outside into the second air intake chamber 4, the inverted V-shaped plate 31 can concentrate the cold air into the second connecting hose 33, which facilitates the second exhaust pipe 27 to cool the electrical distribution chamber 2. In addition, when rainwater falls on the inverted V-shaped plate 31 through the second air intake fan 39, the rainwater accumulates at the bottom of the U-shaped tube 32 through the inverted V-shaped plate 31. At this time, the accumulated rainwater is discharged to the outside through the drain pipe 34.

[0065] Reference Figure 6 The first exhaust pipe 21 and the second exhaust pipe 27 are provided with multiple through holes at the top and bottom. The second exhaust pipe 27 and the first exhaust pipe 21 are arranged alternately. The alternating reciprocating movement of the first exhaust pipe 21 and the second exhaust pipe 27 can effectively and quickly cool down the power distribution compartment 2 from all directions. The alternating arrangement of the first exhaust pipe 21 and the second exhaust pipe 27 can prevent the airflows discharged by the first exhaust pipe 21 and the second exhaust pipe 27 from colliding and canceling each other when exhausting above and below the support plate 5, thus affecting the heat dissipation efficiency.

[0066] Reference Figure 8 The top of the cabinet 1 is rotatably connected to a bidirectional screw 43 via a base. A rotary motor 44 is bolted to the top of the cabinet 1, and the output shaft of the rotary motor 44 is fixedly connected to the bidirectional screw 43 via a coupling. Two brackets 45 are slidably connected to the top of the cabinet 1 and threaded to the bidirectional screw 43. The two brackets 45 are located on the positive and negative thread sections of the bidirectional screw 43, respectively. A first rain shield 46 and a second rain shield 4 are bolted to the top of the two brackets 45, respectively. 7. The top of the second rain shield 47 touches the bottom inner wall of the first rain shield 46. The fit between the first rain shield 46 and the second rain shield 47 not only prevents rainwater from entering the ventilator 38, but also does not hinder the ventilator 38 from expelling the hot air in the power distribution compartment 2 to the outside. On sunny days, the first rain shield 46 and the second rain shield 47 are opened, exposing the ventilator 38. After the hot air expelled by the ventilator 38 is no longer blocked by the first rain shield 46 and the second rain shield 47, it can accelerate the dissipation of hot air.

[0067] Working principle: When components need to be mounted on the tray 5, the components are placed on top of the bracket 8. Rotating the double-threaded rod 9 causes the two nut blocks 11 to move towards the center. The nut blocks 11, through the rotation of the first connecting rod 13, lift the bracket 8 upwards, creating a larger gap between the components and the tray 5. This facilitates heat dissipation, allowing air to carry away heat through the gap. The nut blocks 11, through the fixing rod 14, drive the slider 12 to move. The slider 12, through its top first connecting rod 13, also lifts the bracket 8. Thus, the slider 12 and its top first connecting rod 13 can effectively support the bracket 8. It serves a balancing function. Additionally, when the bracket 8 moves upwards, multiple clamping plates 15 move towards the center via connecting rod 16 and second connecting rod 18. This allows the multiple clamping plates 15 on both sides of the bracket 8 to clamp the components on top of the bracket 8, facilitating heat dissipation and easy component fixation. Furthermore, connecting wires can pass through the wire hole 7 to connect to the components. When heat dissipation is needed for the components in the power distribution compartment 2, the first intake fan 19 and the second intake fan 39 are activated. The first intake fan 19 and the second intake fan 39 draw in outside cold air through the V-shaped plate 20 and the inverted V-plate 31, sealing it off and expelling it into the first connecting pipe 22. In the second connecting pipe 28, the drive motor 25 is then started to drive the reciprocating screw 24 to rotate. The reciprocating screw 24 drives the sliding block 23 and the first connecting pipe 22 to slide back and forth in the first air intake chamber 3. The first connecting pipe 22 drives the two first exhaust pipes 21 to slide back and forth along the first through hole 40. The cold air in the first connecting pipe 22 is discharged into the power distribution chamber 2 through the through holes above and below the first exhaust pipe 21, which can evenly cool the inside of the power distribution chamber 2. The gap between the components and the support plate 5 facilitates the cold air to quickly carry away the heat of the components. When the first exhaust pipe 21 moves back and forth, one of the first exhaust pipes... The sliding engagement between the tube 21 and the rotating rod 29 via the protrusion 30 enables the rotating rod 29 to reciprocate. The sliding engagement between the rotating rod 29 and the second connecting tube 28 enables the second connecting tube 28 to drive the second exhaust pipe 27 to slide back and forth along the second through hole 41. The alternating reciprocating movement of the first exhaust pipe 21 and the second exhaust pipe 27 effectively and quickly cools the power distribution chamber 2 from all directions. Meanwhile, cold air from the outside enters the first air intake chamber 3 and the second air intake chamber 4 through the air inlet 35, and can enter the power distribution chamber 2 through the first through hole 40, the second through hole 41 and the third through hole 42, further cooling the power distribution chamber 2.During the rainy season, rainwater falls onto the V-shaped plate 20 through the air inlet 35 and is drained through the drain hole 37. When rainwater falls onto the inverted V-shaped plate 31 through the second air intake fan 39, it accumulates at the bottom of the U-shaped tube 32. The accumulated rainwater is then drained to the outside through the drain pipe 34. The rotating motor 44 is started to drive the bidirectional screw 43 to rotate. The bidirectional screw 43 drives the two supports 45 to move towards the middle, and the first rain shield 46 and the first rain shield 46 close together. The first and second rain deflectors 46 and 47 not only prevent rainwater from entering the power distribution compartment 2 through the fan 38, but also allow the fan 38 to expel hot air from the compartment 2 to the outside. Furthermore, on sunny days, when the first and second rain deflectors 46 and 47 are open, exposing the fan 38, the hot air expelled by the fan 38, no longer blocked by the deflectors, can dissipate more quickly.

[0068] However, as is well known to those skilled in the art, the working principles and wiring methods of the first intake fan 19, the second intake fan 39, the diffuser fan 38, the rotating motor 44, and the drive motor 25 are commonplace and belong to conventional methods or common knowledge.
