Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a heat dissipation and dust removal distribution cabinet. Background Art

[0002] In power systems, distribution cabinets, as key end-stage equipment, undertake important tasks such as power distribution, control, and protection. They are widely used in many fields, including industry, construction, healthcare, and transportation. Traditional distribution cabinets have exposed many problems during long-term operation.

[0003] Existing power distribution cabinets (PDCs) have deficiencies in heat dissipation and dust removal. During operation, the electrical components within the PDCs continuously generate heat. Heat is typically dissipated naturally through heat dissipation holes and heat sinks, or through forced cooling with extraction fans and refrigeration mechanisms. However, in actual use, dust in the air significantly impairs heat dissipation. Over time, large amounts of dust enter the PDCs and gradually accumulate. Dust adheres to the surfaces of the electrical components, forming an insulating layer that significantly hinders heat transfer to the outside world and reduces heat dissipation efficiency. Traditional air-cooling methods also employ single-sided extraction fans or forced injection ventilation. When the PDCs are divided into three compartments (upper, middle, and lower), regardless of top air intake or other forced ventilation methods, the air, after absorbing heat through these three compartments, will experience a significant increase in temperature by the time it reaches the final compartment. This makes it difficult for the incoming high-temperature airflow to effectively remove the heat generated by the electrical components. Furthermore, the wind force gradually weakens, causing the carried dust to easily adhere and accumulate in the final compartment, absorbing moisture from the air to form a conductive water film, reducing insulation resistance and increasing the risk of short circuits. Summary of the Invention

[0004] The purpose of the present invention is to overcome the deficiencies in the prior art and provide a heat dissipation and dust removal distribution cabinet. The fan blades are blown by external air to guide the air into a fixed cylinder for transportation. The extracted air first passes through a bipolar alternating ion generator, and the bipolar ions are used to neutralize the electrostatic charge in the air, while eliminating the original static electricity in the air. The air after the static electricity treatment enters the fixed shell, and is further heat-exchanged and cooled with the coolant. It is then sent into the distribution cabinet through the air outlets in multiple intervals. In the process of heat dissipation and cooling, it can effectively neutralize the static electricity on the surface of the electrical components and weaken the adsorption force between the dust and the components due to static electricity. Combined with the effect of the blowing airflow, the dust originally attached to the electrical components due to static electricity is more easily blown away, thereby achieving efficient heat dissipation while completing dust removal simultaneously.

[0008] Preferably, the liquid heat exchange drive component includes a heat exchange tube, which is embedded in the interior of the fixed shell, and the top of the heat exchange tube is connected to the output end of the circulation pump through a water pipe, and the bottoms on both sides of the heat exchange tube are connected to the back of the fixed box through a return pipe.

[0010] Preferably, the air flow duct component includes a fixed plate, which is connected to the back of the distribution cabinet, and the inner side of the fixed plate is rotatably connected to a fixed cylinder, and the inside of the fixed cylinder is rotatably connected to a fixed rod, and multiple fixed rods are driven to rotate synchronously through transmission parts, and the surface of the fixed rod is connected to a fan blade, and a bipolar alternating ion generator is fixedly installed on the bottom of the fixed cylinder, and a filter is fixedly installed on the surface of the fixed rod, and the filter cleans the dust attached to its surface through a cleaning part.

[0012] Preferably, the cleaning member includes a connecting plate, the connecting plate is connected to the outer side of the fixing plate, the inner side of the connecting plate is connected to a cleaning brush, and the cleaning brush is in contact with the filter screen.

[0013] Preferably, the auxiliary extraction mechanism includes an extraction box, which is embedded in the back of the cabinet door. An extraction fan is embedded in the front of the cabinet door, and the back of the extraction fan is connected to the front of the extraction box.

[0014] Preferably, auxiliary motors are fixedly mounted on both sides of the back side of the power distribution cabinet, and the output ends of the auxiliary motors are connected to the outer ends of the fixing rods.

[0015] The beneficial effects of the present invention are: 1) The fan blades are blown by external air and guide the air into the fixed cylinder for transportation. The extracted air first passes through the bipolar alternating ion generator, which uses bipolar ions to neutralize the static charge in the air and eliminate the original static electricity in the air. The air after static electricity treatment enters the fixed shell, further exchanges heat with the coolant for cooling, and is then sent into the distribution cabinet through the air outlets in multiple sections. In the process of heat dissipation and cooling, the static electricity on the surface of the electrical components can be effectively neutralized, and the adsorption force between dust and components due to static electricity can be weakened. Combined with the effect of the blowing airflow, the dust originally attached to the electrical components due to static electricity is more easily blown away, thereby achieving efficient heat dissipation and simultaneous dust removal.

[0016] 2) By setting up ventilation pipes and heat exchange square tubes, the ventilation pipes are embedded in the circulation pipes and are in direct contact with the coolant flowing therein. The heat in the coolant is taken away by the circulation of external air, thereby cooling the coolant that is continuously circulated. Similarly, the heat exchange square tubes are embedded in the outer surface of the circulation pipes, exchanging heat with them and taking away heat to reduce their operating temperature.

The filter 57 is cleaned of dust attached to its surface by a cleaning member 58.

[0018] 4) When the extraction fan is started, the air inside the extraction box is extracted, so that the multiple wind suction ports on the back of the extraction box extract the heat-absorbing air flowing through the surface of the electrical components in a direct current in different areas, so that the air after heat dissipation and dust removal of the electrical components is drawn into the extraction box and then quickly discharged by the extraction fan. This can avoid the fan used for heat dissipation in each area being discharged after one use, avoiding the impact of outward heat dissipation when used twice, and can quickly extract the dust attached to the electrical components after being blown away, avoiding the dust from attaching again.

[0019] 5) By providing a connecting plate and a cleaning brush, after the filter screen filters the air, the dust attached to the surface can be cleaned by the cleaning brush as it rotates with the fixed rod, so that the dust attached to the surface is cleaned and a good air filtration effect is continuously maintained.

[0020] 6) By providing the first sealing ring and the second sealing ring, the concave-convex connection between the first sealing ring and the second sealing ring can prevent the coolant flowing inside the fixed tube from overflowing, and play a secondary sealing effect at the rotating connection between the fixed ring and the fixed tube.

[0032] The following is combined with Figure 1-10 The technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0033] In the description of the present invention, it should be understood that the terms "longitudinal", "transverse", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0034] A heat dissipation and dust removal power distribution cabinet comprises a power distribution cabinet body 1, a cabinet door 2 is movably connected to the front of the power distribution cabinet body 1 via a pin shaft, and further comprises: The liquid circulation mechanism 3 is provided on the top of the power distribution cabinet 1 and is used to drive the cooling liquid to circulate; The liquid heat exchange driving component 4 is arranged on the back of the power distribution cabinet 1, and is used to exchange heat with the coolant and generate a driving force through the upward and downward flow impact force of the coolant to drive the air circulation to flow toward the power distribution cabinet 1; The air flow channel 5 is provided on the back of the power distribution cabinet 1 and is used to guide the external air and then neutralize the static electricity of the air to be heat exchanged; A fixed shell 6 is fixedly mounted on the back of the power distribution cabinet 1. An air outlet 7 is provided on the inner wall of the power distribution cabinet 1. An air guide shell 8 is connected to the inner wall of the fixed shell 6. The air guide shell 8 is located outside the air outlet 7. The auxiliary extraction mechanism 9 is embedded in the cabinet door 2 and is used to assist the air outlet 7 to allow air to circulate inside the distribution cabinet 1. The air discharged from the air outlet 7 can be extracted by the auxiliary extraction mechanism 9 after passing through some electrical components, so as to avoid the air absorbing heat and continuing to circulate over a large area to affect the heat dissipation of electrical components in the next interval.

[0035] The space inside the distribution cabinet 1 adopts a modular design and is divided into multiple functional areas, which are used to install electrical components such as circuit breakers, contactors, and relays. The reasonable layout not only optimizes the air flow path, but also facilitates later maintenance. The distribution cabinet 1 is an existing mature product and will not be described in detail here. The top of the air guide shell 8 is provided with multiple circular holes for air circulation, which allows air to enter quickly, and the bottom of the air guide shell 8 is sealed, so that the incoming air can circulate on the surface of the heat exchange tube 41 and then enter the distribution cabinet 1 only through the air outlet 7 for heat dissipation. The air outlet 7 is distributed in multiple areas on the rear side of the inner wall of the distribution cabinet 1, which can provide distributed circulation for air entering from different areas. Moreover, a moisture-absorbing bag can be set between the air outlet 7 and the air guide shell 8 according to the use environment to absorb moisture from the incoming air.

[0036] The liquid circulation mechanism 3 includes a liquid storage box 31, which is connected to the top of the distribution cabinet 1. Both sides of the liquid storage box 31 are connected to flow pipes 32. The bottoms of both sides of the distribution cabinet 1 are connected to fixed boxes 33. The bottom ends of the flow pipes 32 are connected to the tops of the fixed boxes 33. The back of the liquid storage box 31 is connected to a circulation pump 34. The surface of the flow pipe 32 exchanges heat and cools the coolant inside the flow pipe 32 through a heat exchanger 35.

[0037] The circulation pump 34 adopts a variable frequency drive and can automatically adjust the circulation flow rate of the coolant according to the real-time data feedback from the temperature sensor inside the distribution cabinet 1. When the temperature inside the distribution cabinet 1 is low, the flow rate is reduced to save energy; when the temperature rises, the flow rate is accelerated to enhance the heat dissipation effect. When the circulation pump 34 extracts the coolant inside the fixed box 33 through the circulation pipe 32, the coolant flows in the circulation pipe 32 and exchanges heat with the outside air. The extracted coolant is transported from the liquid storage box 31 into the heat exchange pipe 41 by the circulation pump 34 and then flows back into the fixed box 33 through the return pipe to form a circulation of the coolant.

[0038] The heat exchange element 35 includes a ventilation pipe 351, which is embedded in the interior of the circulation pipe 32. The surface of the circulation pipe 32 is embedded with a heat exchange square tube 352. By arranging the ventilation pipe 351 and the heat exchange square tube 352, the ventilation pipe 351 is embedded in the circulation pipe 32 and directly contacts the coolant flowing therein. The heat in the coolant is taken away by the circulation of external air, thereby cooling the coolant that is continuously circulated. Similarly, the heat exchange square tube 352 is embedded in the outer surface of the circulation pipe 32, exchanges heat with it, and takes away heat to reduce its operating temperature.

[0039] The liquid heat exchange drive component 4 includes a heat exchange tube 41, which is embedded in the interior of the fixed shell 6. The top of the heat exchange tube 41 is connected to the output end of the circulation pump 34 through a water pipe, and the bottoms on both sides of the heat exchange tube 41 are connected to the back of the fixed box 33 through a return pipe. The heat exchange tube 41 is divided into multiple sections for heat exchange. The inner sides of the multiple sections of the heat exchange tube 41 are connected to fixed rings 42, and the inner sides of the fixed rings 42 are rotatably connected to fixed tubes 43. The inner wall of the fixed tube 43 is connected to inner circulation blades 44, and the surface of the fixed tube 43 is connected to outer blowing blades 45. The air guide shell 8 is located at the bottom of the outer blowing blades 45, and the surface of the fixed tube 43 is sealed by a seal 46 to the rotating connection between the fixed ring 42 and the fixed tube 43.

[0040] When the coolant delivered by the circulation pump 34 enters the heat exchange tube 41, the coolant water flow impacts the inner circulation blades 44. Through the impact of the upward and downward water flow and the inner circulation blades 44, the inner circulation blades 44 and the fixed tube 43 are driven to rotate on the inner side of the fixed ring 42. The rotation of the inner circulation blades 44 can accelerate the flow rate of the liquid, thereby increasing the delivery speed of the coolant and improving the heat exchange effect. The rotation of the fixed tube 43 drives the outer blowing blades 45 to rotate, so that the outer blowing blades 45 rotate and drive the air to circulate downward, so that the heat-exchanged air is blown into the air guide shell 8, and the air flow rate inside the fixed shell 6 is increased. The fan blades 55 inside the fixed shell 6 and the air flow rate inside the fixed cylinder 52 serving as the air intake are all increased, further accelerating the air flow rate and driving the air through the air outlet 7 into the distribution cabinet 1 for heat dissipation. Combined with the effect of the blowing airflow, the dust originally attached to the electrical components of the distribution cabinet 1 due to static electricity is more easily blown away and the dust removal effect is achieved simultaneously.

[0041] The seal 46 includes a first sealing ring 461, which is connected to the inner side of the fixed ring 42. The surface of the fixed tube 43 is connected to the second sealing ring 462. The inner side of the first sealing ring 461 is clamped with the outer side of the second sealing ring 462. By setting the first sealing ring 461 and the second sealing ring 462, the concave and convex clamping between the first sealing ring 461 and the second sealing ring 462 can prevent the coolant flowing inside the fixed tube 43 from overflowing, and achieve a secondary sealing effect at the rotating connection between the fixed ring 42 and the fixed tube 43.

[0042] The air flow channel component 5 includes a fixed plate 51, which is connected to the back of the distribution cabinet 1. The inner side of the fixed plate 51 is rotatably connected to a fixed cylinder 52, and the inner side of the fixed cylinder 52 is rotatably connected to a fixed rod 53. Multiple fixed rods 53 are driven by a transmission member 54 and a transmission belt 542 to rotate synchronously. The surface of the fixed rod 53 is connected to a fan blade 55. A bipolar alternating ion generator 56 is fixedly installed at the bottom of the fixed cylinder 52. A filter screen 57 is fixedly installed on the surface of the fixed rod 53. The filter screen 57 cleans the dust attached to its surface through a cleaning member 58.

[0043] As an existing known technology, the bipolar alternating ion generator 56 has a working principle that forms an efficient linkage with the dust removal needs. When the electrical components in the distribution cabinet 1 generate static electricity during operation and adsorb dust particles in the air, the bipolar alternating ion generator 56 applies periodic alternating high voltage electricity to the rod-shaped electrodes through a high-voltage power supply, ionizing the air near the electrodes and synchronously generating positive and negative ions. These ions diffuse into the interior of the distribution cabinet 1 with the air flow extracted by the fan blades 55, and actively migrate to the surface of the charged electrical components. The positively charged dust particles are neutralized by the negative ions, and the negatively charged dust is neutralized by the positive ions, achieving the effect of electrostatic neutralization and eliminating the electrostatic adsorption force between the dust and the electrical components. The neutralized dust loses its electrostatic bondage and is more easily blown away and extracted from the surface of the electrical components under the action of the cooling airflow sent out by the air outlet 7 and the suction force of the auxiliary extraction mechanism 9, thereby avoiding dust accumulation to form an insulation layer, and achieving the dual dust removal effects of electrostatic neutralization and airflow blowing in the process of synchronous heat dissipation.

[0044] The cleaning member 58 includes a connecting plate 581, which is connected to the outer side of the fixed plate 51. A cleaning brush 582 is connected to the inner side of the connecting plate 581. The cleaning brush 582 is in contact with the filter 57. By arranging the connecting plate 581 and the cleaning brush 582, after the filter 57 filters the air, the dust attached to its surface can be cleaned by the cleaning brush 582 during the process of following the rotation of the fixed rod 53, so that the dust attached to its surface is cleaned and a good air filtration effect is maintained continuously.

[0045] The transmission member 54 includes a transmission wheel 541, which is connected to the surface of the fixed rod 53. The surface of the transmission wheel 541 is connected to the transmission belt 542. By setting the transmission wheel 541 and the transmission belt 542, multiple fixed rods 53 can be synchronously driven together. When the fan blades 55 on any fixed rod 53 are driven to rotate by wind force, the transmission of the transmission wheel 541 and the transmission belt 542 can drive multiple fixed rods 53 to rotate synchronously, so that the multiple fan blades 55 can rotate with the help of each other to guide the air.

[0046] The auxiliary extraction mechanism 9 includes an extraction box 91, which is embedded in the back of the cabinet door 2. The front of the cabinet door 2 is embedded with an extraction fan 92. The back of the extraction fan 92 is connected to the front of the extraction box 91. When the extraction fan 92 is started, the air inside the extraction box 91 is extracted, so that the multiple wind suction ports on the back of the extraction box 91 are divided into different areas to extract the heat-absorbing air flowing through the surface of the electrical components in a direct current, so that the air after heat dissipation and dust removal of the electrical components is drawn into the extraction box 91 and then quickly discharged by the extraction fan 92. Firstly, it can avoid the fan used for heat dissipation in each area from being discharged after one use, avoiding the influence of outward heat dissipation when used twice. Secondly, it can quickly extract the dust attached to the electrical components after blowing it away, avoiding the dust from attaching again.

[0047] Auxiliary motors 10 are fixedly installed on both sides of the back of the distribution cabinet 1, and the output end of the auxiliary motor 10 is connected to the outer end of the fixed rod 53. By setting the auxiliary motor 10, when the fan blades 55 rotate discontinuously under low wind force, it can be used to actively drive the fixed rod 53, firstly rotating the fan blades 55 and then forming an air flow channel for the air; secondly, when the air flow rate needs to be increased, the auxiliary power of the auxiliary motor 10 can be used to make the fixed rod 53 and the fan blades 55 rotate more smoothly and quickly, thereby guiding the air.

[0048] A heat dissipation and dust removal distribution cabinet, the working process of which is as follows: first, the fan blades 55 rotate to filter the external air through the filter 57 and then draw it into the interior of the fixed cylinder 52. This step can reduce the entry of dust, and the bipolar alternating ion generator 56 applies periodic alternating high voltage electricity to the rod-shaped electrode through the high-voltage power supply, so that the air near the electrode is ionized, the static electricity neutralizes the air, and the air flows into the interior of the fixed shell 6 to exchange heat with the heat exchange pipe 41, further reducing the temperature of the air used for heat dissipation, and the circulating pump 34 draws the coolant stored in the circulation pipe 32 and the fixed box 33 into the liquid storage box 31, and then The circulating pump 34 delivers the coolant into the heat exchange tube 41, causing the coolant to flow downward and impact the inner circulation blades 44, driving the inner circulation blades 44 to strengthen the circulation of the coolant, and driving the fixed tube 43 and the outer blowing blades 45 to rotate, driving the cooled air to circulate downward in a concentrated manner, so that the heat-exchanged air is blown into the air guide shell 8 through the air outlet 7 and into the interior of the distribution cabinet 1 for effective heat dissipation and static removal. The blowing airflow, combined with the static neutralization effect, makes it easier for the air blown onto the electrical components inside the distribution cabinet 1 to blow away the dust attached by static electricity, thereby achieving the dust removal effect simultaneously during the heat dissipation process; After the cooling air ejected from the air outlet 7 is sprayed and cooled in different upper, middle and lower areas inside the distribution cabinet 1, the extraction fan 92 extracts and collects the air that has been cooled once in the internal area of ​​the distribution cabinet 1 through multiple suction ports on the back of the extraction box 91 corresponding to multiple different areas in the upper, middle and lower areas inside the distribution cabinet 1, to prevent the air from absorbing heat from overflowing, and to centrally extract and discharge the hot air through multiple suction ports on the back of the extraction box 91, and to avoid the hot air from circulating on the surface of the electrical components for a second time, causing the heat-dissipating air to overflow and affect the heat dissipation in other areas, and can quickly extract the dust attached to the electrical components after being blown away, to prevent the dust from attaching for the second time, thereby effectively dissipating heat and removing dust inside the distribution cabinet 1.
