DETAILED DESCRIPTION

[0036] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0037] like Figures 1 to 9As shown, the present invention provides a technical solution, a high-efficiency heat dissipation structure for an inverter, comprising a base 1, a support ring 3 is fixedly connected to the top of the base 1, a cabinet 4 is rotatably connected to the top of the support ring 3, a first motor 2 is fixedly connected to the top of the base 1, an output end of the first motor 2 is fixedly connected to the cabinet 4, an outer wall of the cabinet 4 is rotatably connected to a cabinet door 42, a first cavity 5 is opened on the top of the cabinet 4, a filter screen 8 is fixedly connected to the inner wall of the first cavity 5, two brackets 6 are symmetrically fixedly connected to the inner wall of the first cavity 5 and located above the filter screen 8, a second motor 7 is fixedly connected between the two brackets 6, and a stirring rod 20 is fixedly connected to the outer wall of the output end of the second motor 7 and located below the filter screen 8.

[0038] Through the above technical scheme, by setting the first cavity 5, rainwater can be stored when it rains, and the cabinet 4 can be cooled by the rainwater to prevent the inverter in the cabinet 4 from being overheated and damaged during use. By setting the filter 8, branches and leaves can be prevented from entering the first cavity 5. The second motor 7 is started to drive the stirring rod 20 to rotate, and the rainwater in the first cavity 5 is stirred, so that the surface of the rainwater will constantly change while being stirred, thereby accelerating the volatilization of the rainwater in the first cavity 5, and then accelerating the cooling speed of the cabinet 4. By setting a rotating cabinet door 42, the cabinet 4 can be opened for installation and maintenance of the inverter.

[0039] Specifically, the output end of the second motor 7 extends to the interior of the cabinet 4 and is fixedly connected to a reciprocating screw 24. The outer wall of the reciprocating screw 24 is fixedly connected to a fixing ring 16. The outer wall of the fixing ring 16 is equidistantly fixedly connected to a plurality of blades 17. The blades 17 are installed at an angle. Two heat dissipation grooves 19 are symmetrically provided on the outer wall of the cabinet 4. The bottoms of the two heat dissipation grooves 19 are both inclined. The inner wall of the cabinet 4 is symmetrically fixedly connected to two guide plates 18 below the heat dissipation grooves 19. The two guide plates 18 are both arranged in a horizontal V shape.

[0040] Through the above technical scheme, due to the low density of hot air, after heat is generated in the cabinet 4, the hot air floats upward and accumulates at the bottom of the first cavity 5. The rainwater in the first cavity 5 is heated by the hot air, and the volatilization of the rainwater is further accelerated. Therefore, under the action of heat transfer, the cabinet 4 is effectively cooled down, and the second motor 7 is started to drive the reciprocating screw 24 to rotate counterclockwise, so that the fixed ring 16 rotates counterclockwise, driving the blade 17 to rotate counterclockwise. When the blade 17 rotates, an upward vortex is formed, which accelerates the hot air on the inverter to float upward. The two guide plates 18 are set to facilitate the passage of hot air, and the hot air can be accumulated on the top of the inner wall of the cabinet 4 to prevent the hot air from flowing downward. The heat dissipation grooves 19 are set to discharge the hot air in the cabinet 4.

[0041] Specifically, two groups of drain ports 9 are symmetrically provided on the outer wall of the cabinet 4 and located above the heat dissipation groove 19. The drain ports 9 are located below the filter 8. Both groups of drain ports 9 are communicated with the first cavity 5. Several heat dissipation components are provided on the outer wall of the cabinet 4 and located below the heat dissipation groove 19. The heat dissipation components include a first heat dissipation fin 10 and a second heat dissipation fin 11. The first heat dissipation fin 10 and the second heat dissipation fin 11 are both fixed on the outer wall of the cabinet 4. The first heat dissipation fin 10 is located above the second heat dissipation fin 11. The first heat dissipation fin 10 is arranged in a V shape, and the second heat dissipation fin 11 is arranged in an inverted V shape. The length of the first heat dissipation fin 10 is greater than that of the second heat dissipation fin 11. A drain port 15 is provided at the bottom of the first heat dissipation fin 10, and a baffle 14 is fixedly connected to the top of the first heat dissipation fin 10 and the second heat dissipation fin 11.

[0042] The heat of the cabinet 4 is absorbed by the first heat sink 10 and the second heat sink 11, and the contact area between the cabinet 4 and the outside air is increased, which can better help the cabinet 4 to dissipate heat. When the rainwater surface in the first cavity 5 reaches the position of the drain port 9, the rainwater flows downward along the drain port 9, falls on the first heat sink 10, and flows along the inclined surface at the top of the first heat sink 10. When the rainwater flows to the drain port 15, it flows downward along the drain port 15, falls on the second heat sink 11, and flows along the inclined surface at the top of the first heat sink 10, and falls on the first heat sink 10 below. In this way, the rainwater falling from the drain port 9 flows along several groups of first heat sinks 10 and second heat sinks 11 alternately. When the rainwater flows on the first heat sink 10 and the second heat sink 11, the first heat sink 10 and the second heat sink 11 are cooled by heat transfer, thereby accelerating the heat dissipation of the cabinet 4 by the first heat sink 10 and the second heat sink 11.

[0043] Specifically, a plurality of baffle blocks 12 are fixedly connected to the tops of the first heat dissipation fins 10 and the second heat dissipation fins 11 at equal distances. The tops of the baffle blocks 12 are configured as symmetrical inclined surfaces, and a liquid accumulation groove 13 is provided between two adjacent baffle blocks 12 .

[0044] Through the above technical scheme, the baffle block 12 is set to delay the residence time of rainwater on the first heat dissipating fin 10 and the second heat dissipating fin 11, and the liquid collection tank 13 is set to accumulate part of the rainwater on the first heat dissipating fin 10 and the second heat dissipating fin 11, and the cooling effect on the first heat dissipating fin 10 and the second heat dissipating fin 11 is improved through the volatilization of rainwater.

[0045] Specifically, a second cavity 46 is provided inside the cabinet 4 and below the fixed ring 16, a slide plate 31 is slidably connected to the bottom of the inner wall of the second cavity 46, and two water storage buckets 32 are symmetrically fixedly connected to the top of the slide plate 31, and two water inlets 22 are symmetrically provided on the outer wall of the cabinet 4, and both water inlets 22 are communicated with the second cavity 46, and two water receiving buckets 21 are symmetrically fixedly connected to the outer wall of the cabinet 4 and located at the bottom of the water inlet 22, and an extrusion block 33 is symmetrically fixedly connected to the top of the inner wall of the second cavity 46, and the two extrusion blocks 33 are respectively attached to the inner walls of the two water storage buckets 32, and two first infusion grooves 23 are symmetrically provided inside the cabinet 4, and the top of the first infusion groove 23 is communicated with the heat dissipation groove 19, and the bottom of the first infusion groove 23 is communicated with the second cavity 46, and a driving assembly is provided on the outer wall of the reciprocating screw 24.

[0046] Through the above technical solution, rainwater sliding down from the second heat dissipating fin 11 enters the water receiving bucket 21 and enters the second cavity 46 along the water inlet 22. The rainwater entering the second cavity 46 is stored in the water storage bucket 32. After the rainy season ends, if the inverter heats up, the second motor 7 is started to drive the reciprocating screw rod 24 to rotate clockwise. The driving assembly is set to drive the slide plate 31 to move up and down reciprocatingly, so that the water storage bucket 32 ​​moves up and down reciprocatingly. When the water storage bucket 32 ​​moves upward, the water storage bucket 32 ​​can The water inlet 22 is blocked to prevent the water storage bucket 32 ​​from flowing out from the water inlet 22, and the extrusion block 33 enters the water storage bucket 32. Under the extrusion of the extrusion block 33, the rainwater in the water storage bucket 32 ​​flows upward along the first infusion groove 23. When the rainwater flows to the heat dissipation groove 19, it flows along the inclined surface of the bottom of the heat dissipation groove 19 to the outer wall of the cabinet 4, and again irrigates the first heat dissipation fins 10 and the second heat dissipation fins 11, thereby recycling the rainwater, improving the heat dissipation effect of the cabinet 4, and avoiding overheating and damage to the inverter after the rain stops.

[0047] Specifically, the driving assembly includes a slider 25, which is connected to the reciprocating screw 24 through a screw nut pair, a sleeve 28 is fixedly connected to the bottom of the inner wall of the second cavity 46, the slider 25 fits inside the sleeve 28, a connecting ring 30 is rotatably connected to the bottom of the slider 25, the connecting ring 30 is fixedly connected to the slide plate 31, the inner wall of the slider 25 is symmetrically slidably connected to two blocks 27, the interior of the slider 25 is symmetrically fixedly connected to two springs 26, the two springs 26 are respectively fixedly connected to the two blocks 27, one side of the two blocks 27 are both set to an inclined surface, the inner wall of the sleeve 28 is symmetrically provided with two slots 29, and the inclined side of the block 27 extends to the inside of the slot 29.

[0048] By the above technical solution, the second motor 7 is started to drive the reciprocating screw 24 to rotate clockwise, so that the slider 25 rotates clockwise, and drives the block 27 to rotate clockwise. When the block 27 rotates to the position of the slot 29, the block 27 is extended into the slot 29 under the action of the spring 26. As the reciprocating screw 24 continues to rotate clockwise, the straight surface of one side of the block 27 presses against the slot 29. Under the action of the slot 29, the block 27 cannot rotate. At this time, as the reciprocating screw 24 rotates clockwise, the slider 25 is driven to move up and down reciprocatingly, thereby driving the connecting ring 30 to move up and down. The second motor 7 is started to drive the reciprocating screw 24 to rotate counterclockwise, so that the slider 25 rotates counterclockwise. When the block 27 rotates to the position of the slot 29, the block 27 enters the slot 29 under the action of the spring 26. As the reciprocating screw 24 continues to rotate, the inclined surface on the other side of the block 27 presses against the slot 29. Under the pressure of the slot 29, the block 27 moves into the slider 25, compressing the spring 26. Therefore, when the reciprocating screw 24 rotates counterclockwise, the slider 25 is driven to rotate counterclockwise on the connecting ring 30.

[0049] Specifically, two groups of arc plates 34 are symmetrically fixedly connected to the inner wall of the cabinet 4, and a second infusion groove 35 is opened on the inner wall of the arc plate 34. Both ends of the second infusion groove 35 are connected to the first infusion groove 23, and a partition plate 36 is fixedly connected to the inner wall of the first infusion groove 23 and located on one side of the second infusion groove 35.

[0050] Through the above technical solution, by setting up a plurality of curved plates 34, the inner wall area of ​​the cabinet 4 is increased, so that the heat inside the cabinet 4 can be transferred to the surface of the cabinet 4 through the curved plates 34. When rainwater flows upward along the first infusion groove 23, it is blocked by the partition 36 and flows along the partition 36 to the second infusion groove 35. The rainwater flows upward through the plurality of second infusion grooves 35, which can effectively take away the heat inside the cabinet 4.

[0051] Specifically, an air inlet 37 is provided on one side of the cabinet 4, and two ventilation slots 38 are symmetrically provided inside the cabinet 4. The two ventilation slots 38 are communicated with the air inlet 37. The inner wall of the ventilation slot 38 is equidistantly fixedly connected with a plurality of protrusions 41, and both sides of the protrusions 41 are set as inclined surfaces. The inner wall of the air inlet 37 is fixedly connected with a guide block 39, and both sides of the guide block 39 are set as inclined surfaces. The outer wall of the cabinet 4 and the two sides of the air inlet 37 are symmetrically fixedly connected with two extension plates 40, and the two extension plates 40 are both installed at an angle.

[0052] Through the above technical solution, the first motor 2 is started to drive the cabinet 4 to rotate, and the direction of the air inlet 37 is adjusted so that the air inlet 37 can face the wind direction. When the wind blows, the wind is guided by the two extension plates 40 so that the wind enters the cabinet 4 through the air inlet 37. The wind is divided by the inclined surfaces on both sides of the guide block 39 so that the wind flows along the two ventilation slots 38. The wind passing through the two ventilation slots 38 can take away the heat of the cabinet 4 and cool the cabinet 4. By setting a number of protrusions 41, the area of ​​the ventilation slots 38 is increased so that the wind can take away more heat.

[0053] Specifically, a plurality of heat conducting plates 43 are fixedly connected to the inner wall of the cabinet door 42 at equal intervals, a side plate 44 is fixedly connected to one side of the heat conducting plate 43 , the side plate 44 is arranged in an arc shape, and a through groove 45 is provided on the inner wall of the heat conducting plate 43 .

[0054] Through the above technical solution, by setting up several heat conducting plates 43, the heat inside the cabinet 4 can be absorbed, and the contact area between the cabinet 4 and the outside air is increased, which helps the cabinet 4 to dissipate heat better. The wind passing through the ventilation slots 38 hits the concave surface of the side plate 44 and flows along the concave surface of the side plate 44. By opening through slots 45 on the heat conducting plates 43, it is convenient for wind to pass through several heat conducting plates 43, and the heat on the surface of the heat conducting plates 43 can be taken away more quickly by the flow of wind.

[0055] An operating method of a high-efficiency heat dissipation structure for a converter is applicable to the above-mentioned high-efficiency heat dissipation structure for a converter. The operating method has the following steps:

[0056] S1: The cabinet 4 is installed outdoors, and the first cavity 5 is used to store water when it rains. The second motor 7 is started to control the reciprocating screw 24 to rotate counterclockwise to rotate the blades 17 to accelerate the upward floating of the hot air on the converter, and at the same time, the stirring rod 20 is controlled to rotate to stir the rainwater in the first cavity 5;

[0057] S2: Start the first motor 2 to drive the cabinet 4 to rotate and adjust the direction of the air inlet 37 so that the air inlet 37 faces the wind direction;

[0058] S3: After the rainy season ends, the second motor 7 is started to control the reciprocating screw 24 to rotate clockwise, driving the water storage bucket 32 ​​to move up and down reciprocatingly, and the rainwater in the water storage bucket 32 ​​is squeezed back onto the first heat dissipation fins 10 and the second heat dissipation fins 11 by squeezing.

[0059] When in use, the first cavity 5 is provided to store rainwater when it rains, and the cabinet 4 is cooled by the rainwater to prevent the inverter in the cabinet 4 from being overheated and damaged during use. The filter screen 8 is provided to prevent branches and leaves from entering the first cavity 5. The second motor 7 is started to drive the stirring rod 20 to rotate, and the rainwater in the first cavity 5 is stirred, so that the surface of the rainwater is constantly renewed and expanded, and the volatilization of the rainwater in the first cavity 5 is accelerated, thereby accelerating the cooling speed of the cabinet 4. The cabinet 4 can be opened for installation and maintenance of the inverter by providing a rotating cabinet door 42. Due to the low density of hot air, after heat is generated in the cabinet 4, the hot air floats upward and accumulates at the bottom of the first cavity 5, and the rainwater in the first cavity 5 is heated by the hot air, further increasing The volatilization of rainwater is accelerated, thereby effectively cooling the cabinet 4 under the effect of heat transfer, and the second motor 7 is started to drive the reciprocating screw 24 to rotate counterclockwise, so that the fixing ring 16 rotates counterclockwise, driving the blade 17 to rotate counterclockwise. When the blade 17 rotates, an upward vortex is formed, which accelerates the upward floating of the hot air on the converter. The two guide plates 18 are provided to facilitate the passage of hot air, and the hot air can be accumulated on the top of the inner wall of the cabinet 4 to prevent the hot air from flowing downward. The heat dissipation groove 19 is provided to discharge the hot air in the cabinet 4, and the first heat dissipation fins 10 and the second heat dissipation fins 11 are provided to absorb the heat inside the cabinet 4, and increase the contact area between the cabinet 4 and the outside air, which can better help the cabinet 4 to dissipate heat. When the first air When the surface of the rainwater in the cavity 5 reaches the position of the drain port 9, the rainwater flows downward along the drain port 9, falls on the first heat dissipation fin 10, and flows along the inclined surface of the top of the first heat dissipation fin 10. When the rainwater flows to the drain port 15, it flows downward along the drain port 15, falls on the second heat dissipation fin 11, and flows along the inclined surface of the top of the first heat dissipation fin 10, and falls on the first heat dissipation fin 10 below. In this way, the rainwater falling from the drain port 9 flows along several groups of first heat dissipation fins 10 and second heat dissipation fins 11 alternately. When the rainwater flows on the first heat dissipation fin 10 and the second heat dissipation fin 11, the first heat dissipation fin 10 and the second heat dissipation fin 11 are cooled by heat transfer, and the first heat dissipation fin 10 and the second heat dissipation fin 11 are accelerated. The heat dissipation of the cabinet 4 can delay the residence time of rainwater on the first heat dissipation fin 10 and the second heat dissipation fin 11 through the provided flow blocking block 12, and the provided liquid accumulation groove 13 can accumulate part of rainwater on the first heat dissipation fin 10 and the second heat dissipation fin 11, and the cooling effect on the first heat dissipation fin 10 and the second heat dissipation fin 11 is improved through the volatilization of rainwater, and the rainwater sliding down from the second heat dissipation fin 11 enters the water receiving bucket 21 and enters the second cavity 46 along the water inlet 22, and the rainwater entering the second cavity 46 is accumulated in the water storage bucket 32. After the rainy season ends, if the inverter heats up, the second motor 7 is started to drive the reciprocating screw 24 to rotate clockwise, so that the slider 25 rotates clockwise, and the block 27 rotates clockwise.When the block 27 rotates to the position of the slot 29, the block 27 is extended into the slot 29 under the action of the spring 26. As the reciprocating screw 24 continues to rotate clockwise, the straight surface of one side of the block 27 is pressed against the slot 29. Under the action of the slot 29, the block 27 cannot rotate. At this time, as the reciprocating screw 24 rotates clockwise, the slider 25 is driven to move up and down reciprocatingly, thereby driving the connecting ring 30 to move up and down reciprocatingly, so that the slide plate 31 moves up and down reciprocatingly, and the water storage bucket 32 ​​moves up and down reciprocatingly. When the water storage bucket 32 ​​moves upward, the extrusion block 33 enters the water storage bucket 32. Under the squeezing of 33, the rainwater in the water storage bucket 32 ​​flows upward along the first infusion groove 23. When the rainwater flows to the heat dissipation groove 19, it flows along the inclined surface of the bottom of the heat dissipation groove 19 to the outer wall of the cabinet 4, and sprinkles the first heat dissipation fins 10 and the second heat dissipation fins 11 again. In this way, the rainwater is recycled, the heat dissipation effect of the cabinet 4 is improved, and the overheating damage of the converter is avoided after the rain stops. By setting a plurality of arc plates 34, the inner wall area of ​​the cabinet 4 is increased, so that the heat inside the cabinet 4 can be transferred to the surface of the cabinet 4 through the arc plates 34. When the rainwater flows upward along the first infusion groove 23, The rainwater is blocked by the partition 36 and flows along the partition 36 to the second infusion groove 35. The rainwater flows upward through the plurality of second infusion grooves 35, which can effectively take away the heat inside the cabinet 4. The first motor 2 is started to drive the cabinet 4 to rotate, and the direction of the air inlet 37 is adjusted so that the air inlet 37 can face the wind direction. When the wind blows, the wind is guided by the two extension plates 40 so that the wind enters the cabinet 4 through the air inlet 37. The wind is divided by the inclined surfaces on both sides of the guide block 39 so that the wind flows along the two ventilation grooves 38. The wind passes through the two ventilation grooves 38 and can take away the heat of the cabinet 4. The cabinet 4 is cooled down by increasing the area of ​​the ventilation slot 38 by setting a plurality of protrusions 41, so that the wind can take away more heat. The plurality of heat conducting plates 43 can absorb the heat inside the cabinet 4 and increase the contact area between the cabinet 4 and the outside air, which helps the cabinet 4 to dissipate heat better. The wind passing through the ventilation slot 38 hits the concave surface of the side plate 44 and flows along the concave surface of the side plate 44. The through slots 45 are provided on the heat conducting plates 43 to facilitate the wind to pass through the plurality of heat conducting plates 43. The flow of wind can more quickly take away the heat on the surface of the heat conducting plates 43.
