Description

Technical Field

[0001] The present invention relates to the technical field of electric control cabinets, and more particularly to an electric control cabinet with auxiliary lateral automatic moisture discharge. Background Art

[0002] An electrical control cabinet is an enclosed or semi-enclosed metal cabinet or screen assembled with switchgear, measuring instruments, protective devices, and auxiliary equipment according to electrical wiring requirements. During normal operation, manual or automatic switches can connect and disconnect circuits. In the event of a fault or abnormal operation, protective devices can disconnect the circuit or issue an alarm. Measuring instruments can display various operating parameters, adjust certain electrical parameters, and provide prompts or signals for deviations from normal operating conditions. An electrical control cabinet typically contains multiple components operating simultaneously, dissipating heat through traditional air convection. When the temperature difference between the inside and outside of the cabinet is small, it is difficult to dissipate the heat within the cabinet. Failure to dissipate the heat promptly can damage the components within the cabinet, negatively impacting power quality and extending the life of the components within the distribution cabinet.

[0003] Among them, the patent with announcement number CN219833495U discloses an electric control cabinet, including a cabinet body, which is rotatably connected to the cabinet door through hinges, a heat dissipation structure fixed inside the cabinet body, and the heat dissipation structure is used to dissipate heat from the electronic components inside the cabinet body. One side of the heat dissipation structure is connected to a temperature sensor, and the temperature sensor is fixed inside the cabinet body. A moisture-proof pad is glued inside the cabinet body; a noise reduction structure, the noise reduction structure is glued to the inside of the moisture-proof pad, and the heat dissipation structure is fixed on the surface of the noise reduction structure.

[0004] This electrical control cabinet uses a temperature sensor to monitor the temperature inside the cabinet. When the temperature reaches a set threshold, a controller controls the cooling fan to accelerate air circulation within the cabinet, achieving automated heat dissipation and timely dissipation of heat within the cabinet. However, the performance of electrical components is closely related to temperature. Within the appropriate temperature range, the conductivity and insulation properties of the components can reach optimal conditions, thereby improving the operating efficiency of the equipment. However, this structure makes it difficult to partition the wires required for different electrical devices during use, causing the heat generated by each electrical device to easily accumulate and hinder rapid heat dissipation. Summary of the Invention

[0005] In order to overcome the above-mentioned defects of the prior art, the present invention provides an electric control cabinet with auxiliary lateral automatic moisture discharge, aiming to solve the problems raised in the above-mentioned background technology.

[0006] The present invention provides the following technical solution: an electric control cabinet with auxiliary lateral automatic moisture removal, comprising an electric control cabinet body, wherein the electric control cabinet body is provided with a partition control component; The partition control component includes a main board arranged in the main body of the electric control cabinet, a PCB board is arranged on one side of the main board, a limit frame is arranged on the other side of the main board, a plurality of separation cylinders for separation are arranged in the limit frame, and a limit sleeve is arranged at one end of each of the plurality of separation cylinders, and the limit sleeve is located on the main board; Relays are embedded in the plurality of separation cylinders, and an extension plate is clamped on each of the relays. The extension plate is provided with a plurality of diversion ports for diversion. A plurality of copper bars are arranged in a stacked arrangement, and each of the copper bars is covered with a nylon support frame. The ends of the plurality of copper bars are all fixed with reinforcement pins by bolts, and one end of each of the reinforcement pins is fixed with a reinforcement harness by bolts, one end of the plurality of reinforcement harnesses is provided with a connector, one end of the connector is welded to the limit sleeve, an inverter is welded to one side of the bottom of the main board, an outer cover of the inverter is provided with a first guardrail, the first guardrail is fixed to the main board by bolts, reinforcement cross bars are fixed on both sides of the inner wall of the electric control cabinet body by bolts, connection blocks are fixed on both sides of the main board, and the connection blocks are fixed to the reinforcement cross bars by bolts; It can be seen that in the above technical solution, the air flow inside the electric control cabinet body is extracted by the operation of the air-cooled radiator, and the external air flows into the electric control cabinet body through the dehumidification ports on both sides of the electric control cabinet body, so that the external air flow and the air flow inside the electric control cabinet body circulate, and the heat generated by the operation of the PCB board and the main board is transferred to the fin frame. While the heat is dissipated through the heat conduction of the heat dissipation fins, the air flow passes through the heat dissipation fins to facilitate the rapid discharge of heat, thereby improving the heat dissipation efficiency. At the same time, when the air flow is discharged, it passes through the limit frame to dissipate heat to the structure installed in the limit frame, thereby avoiding damage to the components in the electric control cabinet body, which is beneficial to ensuring the power supply quality and extending the service life of the components in the distribution cabinet. 8. The heat dissipation device of claim 7, wherein the bridge has two opposite ends, and the ends are connected along the length of the bridge to form a circuit board, wherein the bridge has two opposite ends, and the ends are connected along the length of the bridge to form a circuit board. An air-cooled radiator for air diversion is installed on the top of the electric control cabinet body by bolts. Several moisture drainage ports are provided on both sides of the electric control cabinet body. A water baffle is provided on the top of the air-cooled radiator. The water baffle is installed on the air-cooled radiator through a column. The shape of the water baffle is set to be trapezoidal. A deflector is installed on one side of the fin frame by bolts. The deflector is set to be trapezoidal. A cabinet door is hinged on the outside of the electric control cabinet body.

[0007] Technical effects and advantages of the present invention: 1. In the present invention, external air flows into the electric control cabinet body through the dehumidification ports on both sides of the electric control cabinet body, so that the external airflow circulates with the airflow inside the electric control cabinet body. The heat generated by the operation of the PCB board and the main board is transferred to the fin frame. While the heat is dissipated through the heat conduction of the heat dissipation fins, the airflow passes through the heat dissipation fins to facilitate rapid heat discharge, thereby improving the heat dissipation efficiency. At the same time, when the airflow is discharged, it passes through the limit frame to dissipate heat to the structure installed in the limit frame, thereby avoiding damage to the components in the electric control cabinet body, which is beneficial to ensuring the power supply quality and extending the service life of the components in the distribution cabinet. 2. The present invention provides copper bars in each limiting frame to facilitate the connection of circuit breakers, contactors, relays, capacitors and other electrical components to the copper bars, thereby avoiding the interweaving of wires required for different electrical components. Each limiting frame is independently provided to achieve the function of zone control, keep the electrical components working in a suitable temperature environment, reduce the risk of electrical failures, and improve the operational reliability of the electric control cabinet. 3. The present invention uses a nylon support frame mounted on each copper busbar to support the copper busbar, preventing the copper busbars from contacting each other and causing confusion in the conducted current. At the same time, the heat generated by the operation of the PCB and motherboard is transferred to the conduction frame through the conduction frame and heating copper blocks on the outside of the motherboard, and then dissipated through the heating copper blocks, so that the heat on the motherboard can be quickly discharged. 4. The present invention forms several flow channels between the controller, electrodes and mainboard to facilitate air circulation in the main body of the electric control cabinet, effectively discharging moisture from the main body of the electric control cabinet and avoiding the phenomenon of moisture resurgence in the main body of the electric control cabinet; 5. When the heat-conducting arc fins of the present invention are transported by air flow, they are deflected along the axis point of the connection between the hinge rod and the hinge seat through the hinge rod, so that the heat-conducting arc fins can swing in the guide channel. When the heat generated by the operation of the main board is transferred to the heat-conducting arc fins, the heat can be discharged outward through each external fin plate. Combined with the air flow transport and the swing amplitude generated by the heat-conducting arc fins, the heat radiation can be quickly diffused, thereby improving the heat dissipation efficiency and effect.

[0008] In summary, through the corresponding coordinated use of various structures, the heat generated by the operation of the PCB board and the mainboard is transferred to the fin frame. While the heat is dissipated by heat conduction through the heat dissipation fins, the airflow passes through the heat dissipation fins to facilitate the rapid discharge of heat, thereby improving the heat dissipation efficiency. At the same time, when the air is discharged, it passes through the limit frame to dissipate heat to the structure installed in the limit frame, thereby avoiding damage to the components in the main body of the electric control cabinet, which is beneficial to ensuring the power supply quality and extending the service life of the components in the distribution cabinet. The copper busbars set in each limit frame allow the circuit breaker, contactor, relay and capacitor and many other electrical components to be connected to the copper busbars separately, avoiding the wiring of wires required for different electrical components. Each limit frame is set separately to realize the function of zone control, keep the electrical components working in a suitable temperature environment, reduce the risk of electrical failure, and improve the operational reliability of the main body of the electric control cabinet. In addition, the several guide channels formed between the controller, the electrode and the mainboard facilitate the circulation of air in the main body of the electric control cabinet, which can effectively discharge moisture from the main body of the electric control cabinet and avoid the phenomenon of rehumidification in the main body of the electric control cabinet.

At the same time, when the air flow is discharged, it passes through the limit frame 4 to dissipate heat to the structure installed in the limit frame 4, avoiding damage to the components in the electric control cabinet body 1, which is beneficial to ensuring the power supply quality and extending the service life of the components in the distribution cabinet.

A plurality of heating copper blocks 22 for heat dissipation are embedded in the conduction frame 21. A fin frame 23 is provided on the top of the limit frame 4. A plurality of heat dissipation fins 24 are embedded in the fin frame 23. The fin frame 23 is mounted on the main board 2 by bolts. A controller 25 is provided on one side of the electrode 20. The controller 25 is mounted in the electric control cabinet body 1 through a bracket, and a plurality of flow guide channels are formed between the controller 25, the electrode 20 and the main board 2. A plurality of hinge seats 30 are fixedly provided on both sides of the surface of the conduction frame 21, and a hinge rod 31 is hinged on each hinge seat 30. One end of each hinge rod 31 is plugged with a heat-conducting arc fin 32, and the shapes of both ends of each heat-conducting arc fin 32 are set to be arc-shaped. A plurality of external fin plates 33 are plugged into the heat-conducting arc fin 32, and the heat-conducting arc fin 32 is located in the flow guide channel; An air-cooled radiator 26 for air diversion is installed on the top of the electric control cabinet body 1 by bolts. Several moisture drainage ports 27 are provided on both sides of the electric control cabinet body 1. A water baffle 28 is provided on the top of the air-cooled radiator 26. The water baffle 28 is installed on the air-cooled radiator 26 through a column. The shape of the water baffle 28 is set to be trapezoidal. A deflector cover is installed on one side of the fin frame 23 by bolts. The deflector cover is set to be trapezoidal. A cabinet door 29 is hinged on the outside of the electric control cabinet body 1.

[0022] When using the above structure, the staff installs the device at a designated position, and extracts the air flow inside the electric control cabinet body 1 through the operation of the air-cooling radiator 26. The external air flows into the electric control cabinet body 1 through the dehumidification ports 27 on both sides of the electric control cabinet body 1, so that the external air flow and the air flow inside the electric control cabinet body 1 circulate. The heat generated by the operation of the PCB board 3 and the main board 2 is transferred to the fin frame 23. While the heat is dissipated through the heat conduction of the heat dissipation fins 24, the air flow passes through the heat dissipation fins 24 to facilitate rapid heat discharge, thereby improving the heat dissipation efficiency. At the same time, when the air flow is discharged, it passes through the limit frame 4 to dissipate heat to the structure installed in the limit frame 4, thereby avoiding damage to the components in the electric control cabinet body 1, which is beneficial to ensuring the power supply quality and extending the service life of the components in the distribution cabinet. At the same time, the copper bars 9 provided in each limit frame 4 facilitate the connection of various electrical components such as circuit breakers, contactors, relays and capacitors to the copper bars 9, thereby avoiding the interweaving of wires required for different electrical components during wiring. Each limit frame 4 is provided separately to achieve the function of zone control, keep the electrical components working in a suitable temperature environment, reduce the risk of electrical failures, and improve the operational reliability of the electric control cabinet body 1; Furthermore, the nylon support frames 10 sleeved on each copper busbar 9 support the copper busbar 9 to prevent the copper busbars 9 from contacting each other and causing confusion in the conducted current. At the same time, the heat generated by the operation of the PCB board 3 and the motherboard 2 is transferred to the conduction frame 21 through the conduction frame 21 and the heating copper block 22 outside the motherboard 2. The heat is released externally through the heating copper blocks 22, so that the heat on the motherboard 2 is quickly discharged. At the same time, the plurality of guide channels formed between the controller 25, the electrode 20 and the motherboard 2 facilitate air circulation in the electric control cabinet body 1, which can effectively discharge moisture from the electric control cabinet body 1 and prevent the occurrence of moisture resurgence in the electric control cabinet body 1. And when the air flow is transported in the guide channel, the air flow contacts the heat-conducting arc fin 32. When the heat-conducting arc fin 32 is transported by the air flow, it deflects along the axis point of the connection between the hinge rod 31 and the hinge seat 30 through the hinge rod 31, thereby allowing the heat-conducting arc fin 32 to swing in the guide channel. When the heat generated by the operation of the main board 2 is transferred to the heat-conducting arc fin 32, it can be discharged through each external fin plate 33. Combined with the air flow transport and the swing amplitude generated by the heat-conducting arc fin 32, the heat radiation can be quickly diffused, thereby improving the heat dissipation efficiency and effect.

[0023] Different from the prior art, the present application discloses an electric control cabinet with auxiliary lateral automatic moisture removal. The heat generated by the operation of the PCB board 3 and the main board 2 is transferred to the fin frame 23. While the heat is dissipated through the heat conduction of the heat dissipation fins 24, the air flow passes through the heat dissipation fins 24 to facilitate the rapid discharge of heat, so as to improve the heat dissipation efficiency. At the same time, when the air flow is discharged, it passes through the limit frame 4 to dissipate heat to the structure installed in the limit frame 4, thereby avoiding damage to the components in the electric control cabinet body 1, which is beneficial to ensuring the power supply quality and extending the service life of the components in the distribution cabinet. Through the copper busbars 9 set in each limit frame 4, the circuit breakers, contactors, relays and capacitors and many other electrical components are connected to the copper busbars 9 respectively, avoiding the wire wiring required for different electrical components. When staggered together, each limit frame 4 is set separately to realize the function of zoning control, keep the electrical components working in a suitable temperature environment, reduce the risk of electrical failure, and improve the operating reliability of the electric control cabinet body 1, and form several guide channels between the controller 25, the electrode 20 and the main board 2 to facilitate airflow circulation in the electric control cabinet body 1, effectively discharge moisture from the electric control cabinet body 1, and avoid the phenomenon of rehumidification in the electric control cabinet body 1, and when the heat generated by the main board 2 is transferred to the heat-conducting arc fins 32, it can be discharged through each external fin plate 33, and then combined with the airflow transmission and the swing amplitude generated by the heat-conducting arc fins 32 to facilitate rapid diffusion of heat radiation, thereby improving the heat dissipation efficiency and effect.
