Description

Technical Field

[0001] This invention belongs to the field of power distribution cabinet technology, and particularly relates to a high heat dissipation and temperature controllable power distribution cabinet. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in the power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits. Motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a certain circuit of the upper-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load.

[0003] The existing technology (patent application CN218850205U, entitled "A Heat Dissipation and Fire Protection Device for Distribution Cabinets") achieves real-time monitoring, automatic heat dissipation, and fire alarm functions, greatly extending the normal service life of the distribution cabinet and effectively reducing the occurrence of fire and explosion accidents. It also effectively solves the drawback of distribution cabinets always relying on manual maintenance. Its manufacturing cost is low, its stability is high, and it significantly reduces the accident rate, labor costs for routine maintenance, and the time and repair costs of electrical faults, ensuring the stability of daily production operations. However, in the process of implementing this technical solution, at least the following problems were found in the existing technology: After a long period of operation, the internal components of the power distribution cabinet will generate heat. Traditional heat dissipation methods mainly rely on motor-driven cooling fans. Although this method is effective, it undoubtedly increases the operating burden of the power distribution cabinet and the power consumption. Moreover, there is a risk of heat dissipation failure, which requires regular maintenance, making it not worthwhile. Summary of the Invention

[0004] This application aims to at least address one of the technical problems in existing technologies where heat dissipation methods based on the principle of thermal expansion and contraction and using mechanical structures cannot be used for temperature control and regulation of power distribution cabinets without power supply. To this end, this application proposes a high-heat-dissipation, temperature-controllable power distribution cabinet.

[0005] To achieve the above objectives, the specific technical solution of the present invention is as follows: A high heat dissipation and temperature controllable power distribution cabinet includes a power distribution cabinet body, a double cabinet door with a lock is hinged to the front side of the power distribution cabinet body, a fixed cylindrical frame is longitudinally placed in the middle of the power distribution cabinet body, an upper air outlet door is connected to the top of the power distribution cabinet body, and a lower air outlet door is connected to the bottom of the power distribution cabinet body. The fixed cylinder is provided with a heat conduction component, and the heat conduction component includes a memory alloy spring embedded on the upper and lower sides of the fixed cylinder. The upper air outlet valve and the lower air outlet valve are provided with convection components that are matched with the heat conduction component. The convection components include a supporting bottom cover that slides in the upper air outlet valve and the lower air outlet valve. The upper and lower air outlet valves are also equipped with turbulence components that work in conjunction with the convection components, and both sides of the power distribution cabinet are equipped with exchange components that work in conjunction with the heat conduction components. The exchange components include exchange cavities opened on both sides of the internal cavity of the power distribution cabinet.

[0006] Preferably, the thermal conductive component further includes a thermally conductive opening circumferentially formed on the fixed cylinder frame, and the fixed cylinder frame is embedded with a silicone rubber that matches the shape memory alloy spring. The outer sides of both the shape memory alloy spring and the silicone rubber are fixed with lifting slides that slide with the fixed cylinder frame.

[0007] Preferably, a lifting push rod that slides with the fixed cylinder is fixed on the outer side of the lifting slide block, and a sealing sleeve that slides with the lifting push rod is embedded on the inner side of the upper air outlet valve and the lower air outlet valve, and a limiting plate that abuts against the sealing sleeve is fixed on the lifting push rod.

[0008] Preferably, the convection assembly further includes a filter grid that is triangularly and equidistantly embedded in the supporting bottom cover, and an annular cylindrical frame that communicates with the filter grid is fixed on the outer side of the supporting bottom cover. A flow equalization guide is circumferentially connected on the annular cylindrical frame, and the inclination direction of the flow equalization guide is distributed in an axisymmetric state along the transverse axis of the annular cylindrical frame.

[0009] Preferably, the outer side of the annular cylindrical frame is fixed with a sealing top cover that engages with the upper and lower air outlet valves, and the sealing top cover is engaged with the upper and lower sides of the power distribution cabinet in a stepped manner. The inner circumference of the upper and lower air outlet valves is connected with an exchange guide head, and the inclination direction of the exchange guide head is distributed in an axisymmetric state along the transverse axis of the upper and lower air outlet valves.

[0010] Preferably, the turbulence-disrupting assembly includes a lightweight impeller that rotates inside the sealing top cover and is located in an annular frame, the lightweight impeller having a streamlined design.

[0011] Preferably, the lightweight impeller has a turbulence cavity inside, and the lightweight impeller has turbulence openings that are intersected with the fan blades around its perimeter. The bottom of the lightweight impeller is fixed with a turbulence guide that communicates with the turbulence cavity.

[0012] Preferably, the switching component further includes an array of external switching holes on the outside of the power distribution cabinet, and an array of internal switching ports on the inside of the power distribution cabinet, which adopts a strip design. Both the external switching holes and the internal switching ports are interconnected with the switching cavity.

[0013] Preferably, a convex slider fixed to the lifting slide block slides inside the heat conduction opening, and a sliding ring fixed to the outside of the convex slider slides and slides with the fixed cylinder frame. Connecting parts are fixed on both sides of the sliding ring, and a sealing plate that slides with the exchange cavity is fixed on the outside of the connecting parts.

[0014] Preferably, the cross-sectional area of ​​the sealing plate is half the cross-sectional area of ​​the exchange cavity, and the sealing area of ​​the sealing plate is greater than the opening area of ​​the outer exchange hole and the inner exchange port.

[0015] The high heat dissipation and temperature-controlled power distribution cabinet of the present invention has the following advantages: 1. This high-heat-dissipation, temperature-controlled distribution cabinet uses a heat-conducting component to conduct heat from the high heat inside the cabinet through the heat-conducting opening to the shape memory alloy spring and silicone rubber. Based on the principle of thermal expansion, the shape memory alloy spring and silicone rubber expand and deform, simultaneously applying outward pressure to the lifting push rod on the lifting slide, providing mechanical driving force for opening the upper and lower air outlet valves. This replaces the traditional method of cooling by a motor-driven cooling fan, reducing energy consumption and maintenance frequency, and alleviating the operating burden of the distribution cabinet.

[0016] 2. This high heat dissipation and temperature controllable distribution cabinet, through the convection component, under the mechanical top pressure generated by the expansion and deformation of the shape memory alloy spring and the silicone rubber, forces the upper and lower supporting bottom covers, the annular cylinder frame and the sealing top cover to move outward, realizing the opening of the upper and lower air outlet valves. The external cold air rises naturally from the lower air outlet valve into the distribution cabinet, and the heat inside the distribution cabinet overflows from the upper air outlet valve, dissipating heat and cold air through convection, realizing the chimney effect; The filter grille on the bottom cover filters out heat and equalizes the flow of incoming air. The flow guide on the annular frame and the exchange guide on the top cover ensure even and comprehensive exhaust and intake of heat from the upper exhaust valve and cold air from the lower exhaust valve, preventing turbulence.

[0017] 3. This high-heat-dissipation, temperature-controlled distribution cabinet, through a turbulence-inducing component, forces a lightweight impeller to rotate under the impact of the airflow of heat and cold air from the upper and lower annular cylindrical frames. This creates a centrifugal turbulence effect on the overflowing heat and the incoming cold air, accelerating the overflow of heat and the entry speed of cold air, preventing blockage. Furthermore, the turbulence-inducing cavity, turbulence-inducing opening, and turbulence-inducing guide further assist in the turbulence treatment of the overflowing heat and the incoming cold air, preventing turbulence in the two annular cylindrical frames and further enhancing the stabilizing effect of heat overflow and cold air entry.

[0018] 4. This high-heat-dissipation, temperature-controlled distribution cabinet, through the exchange components, under the mechanical pressure generated by the expansion and deformation of the shape memory alloy spring and the silicone rubber, forces the sliding rings on the upper and lower sets of convex sliders to move outward. The sealing plate on the connecting part opens the outer exchange hole and inner exchange port channel of the exchange cavity area, meeting the large-area heat dissipation and ventilation needs of the side of the distribution cabinet, avoiding excessive heat, untimely heat dissipation, and blockage, shortening the heat dissipation time inside the distribution cabinet, and accelerating the entry speed of external cold air, quickly completing heat exchange, and forcing the temperature inside the distribution cabinet to drop and adjust rapidly.

[0022] The present invention will now be described in detail with reference to the accompanying drawings and specific embodiments: like Figures 1-12 As shown, a high heat dissipation and temperature controllable power distribution cabinet of the present invention includes a power distribution cabinet body 1, a double cabinet door 2 with a lock is hinged to the front side of the power distribution cabinet body 1, and a fixed cylinder 3 is longitudinally placed in the middle of the power distribution cabinet body 1. The top of the power distribution cabinet body 1 is connected to an upper air outlet door 4, and the bottom of the power distribution cabinet body 1 is connected to a lower air outlet door 5. A heat-conducting component is provided inside the fixed cylinder frame 3. The heat-conducting component includes shape memory alloy springs 62 embedded on the upper and lower sides of the fixed cylinder frame 3. The heat-conducting component also includes heat-conducting openings 61 circumferentially opened on the fixed cylinder frame 3. The high heat inside the power distribution cabinet 1 reaches the shape memory alloy spring 62 area from the heat-conducting openings 61 on the fixed cylinder frame 3. Based on the principle of thermal expansion, the shape memory alloy spring 62 acts as the main force, and thermal expansion deformation occurs to provide top pressure. Furthermore, the fixed cylinder 3 is embedded with a silicone rubber 63 that matches the memory alloy spring 62. Through the silicone rubber 63, high heat reaches the memory alloy spring 62 area and is also conducted to the silicone rubber 63 area. The silicone rubber 63 acts as an auxiliary force, and based on the principle of thermal expansion, it undergoes thermal expansion deformation to provide auxiliary top pressure. Both the shape memory alloy spring 62 and the silicone rubber 63 are fixed with lifting slides 64 that slide with the fixed cylinder frame 3. The shape memory alloy spring 62 and the silicone rubber 63 are used to expand and press, driving the two sets of lifting slides 64 to slide outward synchronously within the fixed cylinder frame 3. A lifting push rod 65 that slides with the fixed cylinder frame 3 is fixed on the outside of the lifting slide 64. The lifting slide 64 drives the lifting push rod 65 on it to apply outward lifting pressure in sync, providing mechanical driving force for the opening of the upper air outlet valve 4 and the lower air outlet valve 5. This replaces the traditional method of cooling the cooling fan driven by the motor, reduces energy consumption and maintenance frequency, and reduces the operating burden of the power distribution cabinet. The inner sides of the upper air outlet valve 4 and the lower air outlet valve 5 are both fitted with sealing sleeves 66 that slide with the lifting push rod 65. The lifting push rod 65, which moves outward through the sealing sleeves 66, plays a sliding support role, improving the outward movement stability of the lifting push rod 65. A limiting plate is fixed on the lifting push rod 65 to abut against the sealing sleeves 66. The limiting plate plays a limiting and stopping role for the lifting push rod 65 that has moved outward into position.

[0023] like Figures 1-12 As shown, the upper air outlet valve 4 and the lower air outlet valve 5 are equipped with convection components that are matched with the top pressure of the heat conduction component. The convection components include a supporting bottom cover 71 that slides in the upper air outlet valve 4 and the lower air outlet valve 5. The convection components also include a filter grille 72 that is embedded in the supporting bottom cover 71 in a triangular equidistant shape. The filter grille 72 on the supporting bottom cover 71 is used to filter the exhaust heat and the incoming air for dust removal and equalization. Furthermore, an annular cylindrical frame 73 connected to the filter grille 72 is fixed on the outer side of the bottom cover 71. A flow equalization guide head 74 is connected around the annular cylindrical frame 73. The top cover 75 is connected to the upper and lower sides of the power distribution cabinet 1 in a stepped snap-fit ​​manner. An exchange guide head 76 is connected around the inner circumference of the upper air outlet valve 4 and the lower air outlet valve 5. The flow equalization guide head 74 on the annular cylindrical frame 73 and the exchange guide head 76 on the top cover 75 play a uniform and comprehensive role in discharging and introducing the heat overflowing from the upper air outlet valve 4 and the cold air entering from the lower air outlet valve 5, thus preventing turbulence. The outer side of the annular frame 73 is fixed with a sealing top cover 75 that engages with the upper air outlet valve 4 and the lower air outlet valve 5. Under the mechanical pressure generated by the expansion and deformation of the memory alloy spring 62 and the silicone rubber 63, the upper and lower supporting bottom covers 71, the annular frame 73 and the sealing top cover 75 are forced to move outward, thereby opening the channels of the upper air outlet valve 4 and the lower air outlet valve 5. The external cold air rises naturally from the lower air outlet valve 5 into the power distribution cabinet 1, and the heat in the power distribution cabinet 1 overflows from the upper air outlet valve 4, dissipating heat and cold air through convection, thus achieving the chimney effect. Furthermore, the tilt direction of the flow equalization guide 74 is symmetrically distributed along the transverse axis of the annular cylinder 73, and the tilt direction of the exchange guide 76 is symmetrically distributed along the transverse axes of the upper air outlet valve 4 and the lower air outlet valve 5. This ensures the equalization of the overflowing heat and the incoming cold air, preventing turbulence between the heat and cold air within the annular cylinder 73, the upper air outlet valve 4, and the lower air outlet valve 5.

[0024] like Figures 1-12As shown, the upper air outlet valve 4 and the lower air outlet valve 5 are also equipped with turbulence components used in conjunction with the convection components. The turbulence components include a lightweight impeller 81 that rotates inside the sealing top cover 75 and is located in the annular cylinder frame 73. The lightweight impeller 81 adopts a streamlined design. Under the action of overflowing heat and the impact force of the airflow exchanging into the cold air, the speed of the lightweight impeller 81 is accelerated, which plays a centrifugal turbulence role. The lightweight impeller 81 has a turbulence cavity 82 inside, which reduces the overall weight of the lightweight impeller 81 and reduces the rotational burden of the lightweight impeller 81. Turbulence openings 83 are opened around the lightweight impeller 81, which are staggered with the fan blades. Through the turbulence openings 83, the overflowing heat and the incoming cold air can reach the turbulence cavity 82 inside the lightweight impeller 81, which plays an auxiliary role in concentrating turbulence. Furthermore, the bottom of the lightweight impeller 81 is fixed with a turbulence guide head 84 that communicates with the turbulence cavity 82. Through the turbulence guide head 84, the heat and cold air entering the turbulence cavity 82 through the turbulence openings 83 are overflowed and exchanged, which further enhances the stabilization effect of heat overflow and cold air entry.

[0025] like Figures 1-12 As shown, the power distribution cabinet 1 is equipped with exchange components on both sides to match the heat conduction components. The exchange components include exchange cavities 91 opened on both sides of the inner cavity of the power distribution cabinet 1. The exchange components also include external exchange holes 92 arrayed on the outside of the power distribution cabinet 1. The inner side of the power distribution cabinet 1 is arrayed with internal exchange ports 93, which adopt a strip design. The external exchange holes 92 and internal exchange ports 93 are interconnected with the exchange cavities 91, which facilitates the overflow of heat and the exchange of cold air into the operation. A convex slider 94, which is fixed to the lifting slide 64, slides inside the heat conduction opening 61. A sliding ring 95, which slides with the fixed cylinder 3, is fixed on the outside of the convex slider 94. Connecting parts 96 are fixed on both sides of the sliding ring 95. A sealing plate 97, which slides with the exchange cavity 91, is fixed on the outside of the connecting parts 96. Under the mechanical pressure generated by the expansion and deformation of the memory alloy spring 62 and the silicone rubber 63, the sliding rings 95 on the upper and lower sets of convex sliders 94 are forced to move outward. The sealing plate 97 on the connecting parts 96 opens the channels of the outer exchange hole 92 and the inner exchange port 93 in the exchange cavity 91 area, which meets the large-area heat dissipation and ventilation needs of the side of the power distribution cabinet 1, avoids excessive heat, untimely heat dissipation, and blockage, shortens the heat dissipation time in the power distribution cabinet 1, and also accelerates the entry speed of external cold air, quickly completes heat exchange, and forces the temperature in the power distribution cabinet 1 to drop and adjust rapidly. The cross-sectional area of ​​the sealing plate 97 is half that of the cross-sectional area of ​​the exchange cavity 91, and the sealing area of ​​the sealing plate 97 is larger than the opening area of ​​the outer exchange hole 92 and the inner exchange port 93. When the outer exchange hole 92 and the inner exchange port 93 in the exchange cavity 91 area are open, the sealing plate 97 is removed from the outer exchange hole 92 and the inner exchange port 93 area, which facilitates the overflow of heat and the exchange of cold air. When the outer exchange hole 92 and the inner exchange port 93 in the exchange cavity 91 area are closed, the outer exchange hole 92 and the inner exchange port 93 are tightly sealed to prevent heat loss in the distribution cabinet 1 and play a role in heat preservation.

[0026] The working principle of a high heat dissipation and temperature controllable distribution cabinet: When the distribution cabinet 1 generates high heat during long-term operation, the heat is conducted through the heat conduction openings 61 distributed on the upper and lower circumferences of the fixed cylinder 3 to the area of ​​the shape memory alloy spring 62 and the silicone rubber 63. Based on the principle of thermal expansion, the shape memory alloy spring 62 is the main expansion and the silicone rubber 63 is the auxiliary expansion. Then, the shape memory alloy spring 62 and the silicone rubber 63, which undergo double expansion deformation, drive the two sets of lifting slides 64 to slide outward synchronously in the fixed cylinder 3, and synchronously drive the two lifting push rods 65 to slide outward in the sealed sliding sleeve 66. The two outward-pressing lifting rods 65 support the bottom cover 71, which in turn drive the sealing top covers 75 on the two sets of annular cylinder frames 73 to slide outward synchronously within the upper air outlet valve 4 and the lower air outlet valve 5 until the flow equalization guides 74 on the two sets of annular cylinder frames 73 disengage from the upper air outlet valve 4 and the lower air outlet valve 5 and are exposed to the outside of the distribution cabinet 1. At this time, the channels of the upper air outlet valve 4 and the lower air outlet valve 5 are opened, and the cold air outside naturally rises into the distribution cabinet 1 through the opened lower air outlet valve 5. The heat inside the distribution cabinet 1 overflows from the upper air outlet valve 4 and undergoes natural convection heat dissipation. This cycle is repeated to form a chimney effect. Meanwhile, the overflowing heat and the incoming cold air first overflow and exchange into the exchange guides 76 at the upper air outlet valve 4 and the lower air outlet valve 5. After being filtered by the filter grilles 72 on the two sets of supporting bottom covers 71, the heat and cold air overflowing and exchanged into the two sets of annular cylinder frames 73 are subjected to the airflow impact force, which forces the lightweight impeller 81 inside to rotate. This dynamically turbulents the overflowing heat and the incoming cold air. At the same time, the heat and cold air enter the turbulence cavity 82 through the turbulence opening 83. Under the centrifugal force generated by the rotating lightweight impeller 81, the heat and cold air entering the cavity are forced to pass through the turbulence guide 84 and reach the flow equalization guide 74 area at the two sets of annular cylinder frames 73, where they overflow and exchange into the cavity. During this period, the two sets of lifting slide blocks 64 in the outward sliding state drive the two sets of sliding rings 95 to slide outward synchronously along the fixed cylinder frame 3 through the convex slider 94. The two sets of sliding rings 95 drive the sealing plates 97 on the two connecting parts 96 to slide outward in the two sets of exchange cavities 91 and get out of the sealing area of ​​the outer exchange hole 92 and the inner exchange port 93. Then, the channels of the inner and outer exchange holes 92 and the inner exchange port 93 of the two sets of exchange cavities 91 are opened. Then, the heat in the distribution cabinet 1 enters through the inner exchange port 93, passes through the exchange cavity 91 and overflows from the outer exchange hole 92. Conversely, the cold air outside enters through the outer exchange hole 92, passes through the exchange cavity 91 and enters from the inner exchange port 93. After the high heat inside the power distribution cabinet 1 is completely replaced by cold air exchange, its internal temperature drops rapidly. Based on the principle of thermal contraction, the memory alloy spring 62 and silicone rubber 63, which were originally heated and expanded, simultaneously contract and reset their deformation. Under the action of the contraction force, the sealing top covers 75 on the two sets of annular cylinder frames 73 are controlled to re-seal the upper air outlet valve 4 and the lower air outlet valve 5. At the same time, the two sets of sealing plates 97 re-close the channels of the inner and outer exchange holes 92 and the inner exchange port 93 of the two sets of exchange cavities 91. At this time, the power distribution cabinet 1 is in a heat preservation state.
