Description

Technical Field

[0001] The present invention relates to the technical field of electric control cabinets, in particular to an electric control cabinet for an inverter with high efficiency heat dissipation. Background Art

[0002] Frequency converter electrical control cabinets are widely used in the metallurgical, chemical, petroleum, water supply, mining, building materials, and motor industries. They are used to control and regulate the speed of various medium-voltage motor equipment such as pumps, fans, air compressors, rolling mills, injection molding machines, and belt conveyors to achieve energy conservation and improve production efficiency. The core of the frequency converter electrical control cabinet is the frequency converter. The rectifier unit converts the three-phase AC power input from the power grid into DC power. The DC link smoothes the DC voltage through capacitors or inductors to provide a stable DC power supply for the inverter unit. The inverter unit uses power devices such as IGBTs to invert DC power into three-phase AC power with adjustable frequency and voltage, and transmits it to the motor. By adjusting the output frequency, the synchronous speed of the motor is changed to achieve stepless speed regulation.

[0003] During actual operation, the electronic components in the inverter control cabinet will continuously generate a large amount of heat when working. Most existing control cabinets dissipate heat by installing cooling fans on the side walls of the cabinet body and only adopting the internal and external circulation heat exchange method. However, the filter set at the air inlet will be blocked by dust and impurities, resulting in increasingly poor heat dissipation effect. In addition, external dust can easily enter the cabinet and adhere to the electronic components, affecting the heat dissipation effect and normal operation of the electronic components. Existing inverter control cabinets basically have the electronic components fixed on the inner wall of the control cabinet. When the electronic components need to be repaired, the small space in the control cabinet will cause inconvenience. Summary of the Invention

The end of the connecting plate 11 away from the bottom plate 23 is fixedly connected to the mounting plate 5. A rotating groove 12 is provided on the heat insulation plate 6. A shaft 27 is rotatably connected in the rotating groove 12. Both ends of the shaft 27 are fixedly connected to a coil spring 28. The outer wall of the shaft 27 is rotatably connected to a thermal insulation cloth 26. The end of the thermal insulation cloth 26 away from the shaft 27 is fixedly connected to the connecting plate 11. A plurality of card plates 29 are evenly installed on the end of the mounting plate 5 away from the back plate 38. The heat sink 10 is fixedly connected in the card plate 29. The end of the air inlet pipe 15 close to the side plate 2 is fixedly connected to the motor 39. The output end of the motor 39 is fixedly connected to the threaded rod 19, and the threaded rod 19 is rotatably connected to the brush plate 18. A wire hole 13 is provided on the heat insulation plate 6. The end of the heat insulation plate 6 close to the bottom plate 23 is fixedly connected to a temperature sensor. One end of one of the side panels 2 away from the air inlet pipe 15 is rotatably connected to the cabinet door 1.

[0021] In order to improve the heat dissipation effect of the inverter electric control cabinet and automatically clean the filter, the present invention is provided with a heat dissipation component, which divides the electric control cabinet into a low-temperature zone and a high-temperature zone by an insulation board 6. The low-temperature zone below accelerates the air flow rate in the air inlet pipe 15 with the help of fan 19, thereby achieving efficient heat dissipation. The independently arranged air inlet pipe 15 not only avoids the influence of heat from the high-temperature zone, but also prevents dust from entering the interior of the electric control cabinet; fan 20 at the bottom of the high-temperature zone and fan 9 at the top synchronously blow air upward, utilizing the natural convection characteristics of rising hot air to accelerate the discharge of hot air. The temperature sensor can dynamically switch the heat dissipation mode, enabling air cooling at low temperatures and automatically switching to water cooling with the heat sink 10 at high temperatures, taking into account both energy saving and strong heat dissipation requirements; when the pressure difference sensor on the filter detects an abnormality, it will drive the threaded rod 19 to rotate, causing the brush plate 18 to move up and down to automatically clean the filter. At the same time, fan 20 reverses to blow the cleaned dust and impurities away from the filter. Through the above design, not only the heat dissipation effect of the electric control cabinet is improved, but also automatic cleaning of the filter is achieved.

[0022] Specifically, first, since the heat insulation board 6 separates the electric control cabinet into a low-temperature zone and a high-temperature zone, the low-temperature zone of the electric control cabinet is at the bottom and the high-temperature zone is at the top. Integrated circuits, resistors, capacitors, inductors, connectors, communication chips, fuses, etc. are installed in the low-temperature zone, and power MOSFETs, insulated gate bipolar transistors, high-power resistors, transformers, etc. are arranged in the upper high-temperature zone. When the temperature in the electric control cabinet is low, both fan 20 and fan 1 9 are in a low-speed state. Fan 2 20 rotates to make the air inlet pipe 15 pass through the air inlet 3. The air inlet pipe 15 is made of copper pipe. The air flow velocity of the air inlet pipe 15 increases, which will absorb the temperature in the low-temperature zone and automatically cool down the low-temperature zone. The independently arranged air inlet pipe 15 not only avoids the influence of heat from the high-temperature zone, but also reduces the temperature of the low-temperature zone. It can not only eliminate the noise but also prevent dust from entering the electric control cabinet. The fan 20 at the bottom of the high-temperature zone and the fan 1-9 at the top supply air upward synchronously, and use the natural convection characteristics of the rising hot air to accelerate the discharge of the hot air from the installation slot 1-4. It is worth noting that the above-mentioned fan 20 and fan 1-9 are both DC brushless fans, which automatically adjust the speed according to the temperature sensors set in the low-temperature zone and the high-temperature zone. Filters are installed at the air inlet 3, square tube 24 and installation slot 1-4. The side panels 2, bottom panel 23, back panel 38 and top panel 22 of the inverter electric control cabinet are connected and fixed by welding, and the welding points are coated with sealant, which makes the overall rigidity of the electric control cabinet more stable and has good sealing, and can reduce the intrusion of dust and water vapor from the connection gaps, thereby protecting the internal circuit.

[0023] Secondly, when the temperature in the electric control cabinet is very high, the temperature sensor automatically increases the speed of fan 20 and fan 1 9 to speed up the discharge of hot air in the high temperature area. At the same time, the components installed in the high temperature area are in contact with the heat sink 10 in the card board 29. The low viscosity coolant in the microchannel of the heat sink 10 is driven by the water pump to circulate and take away the heat. Through the combined effect of air cooling and water cooling, the heat in the high temperature area is efficiently discharged. It is worth noting that fan 20 and fan 1 9 They are on the same vertical line, and the fan 20 pushes up and the fan 1 9 is arranged on the upper row, so that the cooling effect is more significant. At the same time, the insulation cloth 26 is fitted with the upper surface of the insulation board 6, and the width of the insulation cloth 26 is greater than the width of the telescopic slot 25, reducing the heat transfer from the high temperature area to the low temperature area. It is worth noting that the heat transferred to the low temperature area through the holes and wire holes 13 on the insulation board 6 will be quickly discharged under the heat absorption of the air inlet pipe 15, and will not affect the components in the low temperature area due to the temperature. The above-mentioned insulation cloth 26 is made of Teflon as the main raw material. When the pressure difference sensor installed on the filter at the air inlet 3 detects that the air intake of the filter is reduced, the motor 39 rotates to drive the threaded rod 19 to rotate. , so that the brush plate 18 moves up and down to clean the dust and impurities on the filter screen, and at the same time, the fan 20 rotates in the opposite direction, so that the hot air in the high temperature area is discharged from the air inlet 3 along the air inlet pipe 15. The hot air can dry the moist dust and impurities on the filter screen, reduce the adhesion of dust and impurities, and the brush plate 18 cleans the dust more quickly. When the pressure difference sensor monitoring returns to normal, a storage groove is jointly provided on the side panel 2 and the air inlet pipe 15, and the position of the storage groove is higher than the air inlet 3. The motor 39 drives the brush plate 18 to move up to the highest point of the air inlet 3 to avoid blocking the air intake. At the same time, the fan 20 resumes forward rotation. It is worth noting that the above-mentioned temperature sensor and pressure difference sensor are existing components and will not be repeated here.

[0024] refer to Figure 1-Figure 7 , auxiliary components, including a slide groove 8 opened on the bottom plate 23, a mounting bracket 16 is slidably connected in the slide groove 8, a movable groove 7 is opened on the side plate 2, a mounting plate 5 is slidably connected between the two movable grooves 7, the bottom plate 23 is fixedly connected to the back plate 38 at one end close to the heat insulation plate 6, the mounting bracket 16 is fixedly connected to the sleeve 30 at one end close to the back plate 38, the sleeve 30 is symmetrically provided with two snap-in grooves 37, the back plate 38 is fixedly connected to the guide seat 31 at one end close to the sleeve 30, and the guide The end of the seat 31 away from the back plate 38 is fixedly connected to the guide rod 34, and the outer wall of the guide rod 34 is slidably connected to the frustum 2 36, the end of the guide rod 34 away from the guide seat 31 is fixedly connected to the frustum 1 35, and the sliding rod 32 is slidably connected in the clamping groove 37, and the end of the sliding rod 32 close to the frustum 1 35 is fixedly connected to the clamping block 33, and the end of the mounting frame 16 close to the back plate 38 is fixedly connected to the connecting frame 21, and the mounting frame 16 and the connecting plate 11 are fixedly connected via the connecting frame 21.

[0025] In order to improve the maintenance convenience of the inverter electric control cabinet, the present invention is provided with an auxiliary component. When the mounting bracket 16 is pushed inward, the block 33 in the sleeve 30 is unlocked from the round table 35, and the spring sleeved on the sleeve 30 will drive the mounting bracket 16 and the mounting plate 5 to slide automatically, avoiding the inconvenience of maintenance in the narrow space of the electric control cabinet; after the maintenance is completed, the mounting bracket 16 is pushed inward again, and the block 33 in the sleeve 30 is automatically locked with the round table 35, making the maintenance operation of the electric control cabinet more convenient.

[0026] When the block 33 moves to contact the arc end of the second cone 36, as the mounting bracket 16 continues to move, the block 33 extends out of the clamping groove 37 in the opposite direction and pulls the mounting bracket 16 outward. At this time, the second cone 36 moves along the guide rod 34 to fit the first cone 35. It is worth noting that the maximum diameter ends of the first cone 35 and the second cone 36 are smaller than the diameter of the hole in the sleeve 30, and the distance between the guide seat 31 and the back plate 38 is greater than the length of the guide rod 34. At this time, the block 33 shrinks into the clamping groove 37. When the block 33 passes over the fitting point of the first cone 35 and the second cone 36, the mounting bracket 16 continues to be pulled outward. After the sleeve 30 is unlocked, the mounting bracket 16 moves outward along the slide groove 8 under the rebound force of the spring sleeved on the sleeve 30, and the connecting bracket 21 pulls the mounting plate 5 outward synchronously. It is worth noting that when the mounting bracket 16 moves to the outermost end of the slide groove 8, there is still a distance between the connecting bracket 21 and the air inlet pipe 15, and the connecting bracket 21 moves along the gap between the air inlet pipe 15 and the heat insulation plate 6, and will not contact the above two during the movement. As the mounting plate 5 moves, the rebound force of the coil spring 28 drives the shaft rod 27 to rewind the insulation cloth 26. After the insulation cloth 26 is rewound, the shaft rod 27 does not contact the inner wall of the rotating groove 12, and the rotating groove 12 is not connected to the telescopic groove 25, which will not cause the hot air in the above-mentioned high-temperature area to flow from here to the low-temperature area. When the mounting bracket 16 stops moving in the slide groove 8, the mounting plate 5 also stops moving.

[0027] Secondly, when the inspection is completed, the mounting bracket 16 is pushed inward, and the block 33 in the sleeve 30 is squeezed by the truncated cone 1 35 and shrinks inward along the clamping groove 37, and the mounting bracket 16 is continued to be pushed. When the block 33 passes the maximum diameter end of the truncated cone 1 35, the block 33 extends along the clamping groove 37 under the rebound force of the spring provided on the slide bar 32, and the pushing of the mounting bracket 16 stops. At this time, the spring on the sleeve 30 rebounds and pushes the block 33 to fit tightly with the end of the truncated cone 1 35 close to the truncated cone 2 36. At the same time, the mounting plate 5 moves synchronously under the push of the connecting frame 21, the insulation cloth 26 is pulled out from the shaft 27, the shaft 27 rotates in the opposite direction, and the coil springs 28 at both ends of the shaft 27 are in a gradually compressed state. When the mounting frame 16 is fixed, the mounting plate 5 also stops moving. It is worth noting that after the above-mentioned mounting frame 16 is locked, the distance between the connecting plate 11 and the telescopic slot 25 and the distance between the mounting frame 16 and the slide slot 8 are both greater than the length of the guide rod 34, which will not affect the unlocking of the sleeve 30.

[0028] Working principle of the present invention: Since the heat insulation board 6 divides the electric control cabinet into a low temperature zone and a high temperature zone, when the temperature inside the electric control cabinet is low, the fan 20 and the fan 1 9 are both in a low speed state, and the fan 20 rotates to make the air inlet pipe 15 pass through the air inlet 3. The air inlet pipe 15 is made of copper pipe. The air flow rate of the air inlet pipe 15 increases, which will absorb the temperature in the low temperature zone and automatically cool the low temperature zone. The independently set air inlet pipe 15 not only avoids the influence of heat in the high temperature zone, but also prevents dust from entering the interior of the electric control cabinet. The fan 20 at the bottom of the high temperature zone and the fan 1 9 at the top synchronously supply air upwards, and use the natural convection characteristics of rising hot air to accelerate the discharge of hot air from the installation slot 4. When the temperature inside the electric control cabinet is very high, the temperature sensor automatically increases the fan 20 and the fan 1 9. The speed accelerates the discharge of hot air in the high-temperature area. At the same time, the components installed in the above-mentioned high-temperature area are fitted with the heat sink 10 in the card plate 29. The low-viscosity coolant circulates in the microchannel of the heat sink 10 to take away the heat. Through the combined effect of air cooling and water cooling, the heat in the high-temperature area is efficiently discharged. When the pressure difference sensor installed on the filter at the air inlet 3 detects that the air intake of the filter is reduced, the motor 39 rotates to drive the threaded rod 19 to rotate, so that the brush plate 18 moves up and down to clean the dust and impurities on the filter. At the same time, the fan 20 rotates in the opposite direction, so that the hot air in the high-temperature area is discharged from the air inlet 3 along the air inlet pipe 15. The hot air can dry the moist dust and impurities on the filter, reduce the adhesion of dust and impurities, and the brush plate 18 cleans the dust more quickly. After the pressure difference sensor monitoring returns to normal, the motor 39 drives the brush plate 18 to move up to the highest point of the air inlet 3 to avoid blocking the air intake. At the same time, the fan 20 resumes forward rotation. When maintenance is required, the mounting bracket 16 is pushed inward, and the block 33 on the sleeve 30 is squeezed by the truncated cone 2 36 and moves along the clamping groove 37 to the end away from the truncated cone 2 36. When the block 33 moves to contact the arc-shaped end of the truncated cone 2 36, as the mounting bracket 16 continues to move, the block 33 extends out from the clamping groove 37 in the opposite direction and pulls the mounting bracket 16 outward. At this time, the truncated cone 2 36 moves along the guide rod 34 to fit with the truncated cone 1 35. At this time, the block 33 shrinks into the clamping groove 37. When the block 33 passes over the fitting place between the truncated cone 1 35 and the truncated cone 2 36, the mounting bracket 16 continues to move. When the mounting plate 5 moves outward, the spring 28 of the spring 28 drives the shaft 27 to rewind the heat-insulating cloth 26. After the heat-insulating cloth 26 is rewound, the shaft 27 does not contact the inner wall of the rotating groove 12, and the rotating groove 12 is not connected with the telescopic groove 25, which will not cause the hot air in the high-temperature area to flow from here to the low-temperature area. When the mounting frame 16 stops moving in the slide groove 8, the mounting plate 5 also stops moving. When the maintenance is completed, the mounting frame 16 is pushed inward, and the block 33 in the sleeve 30 is squeezed by the round table 35 and shrinks inward along the card slot 37, continuing to push the mounting frame 16.When the block 33 passes the maximum diameter end of the first cone 35, the block 33 extends along the engaging groove 37 under the rebound force of the spring mounted on the slide bar 32, and stops pushing the mounting bracket 16. At this time, the spring on the sleeve 30 rebounds and pushes the block 33 to tightly fit the end of the first cone 35 near the second cone 36. At the same time, the mounting plate 5 moves synchronously under the push of the connecting frame 21, and the insulation cloth 26 is pulled out from the shaft 27. The shaft 27 rotates in the opposite direction, and the coil springs 28 at both ends of the shaft 27 are gradually compressed. When the mounting bracket 16 is fixed, the mounting plate 5 also stops moving.
