Description

Technical Field

[0001] The utility model relates to the technical field of electric control cabinets, in particular to a heat dissipation and cooling structure of electric components of an electric cabinet. Background Art

[0002] The electrical cabinet is an indispensable part of industrial automation and control systems. It concentrates various electrical equipment and components for controlling, monitoring and protecting electrical equipment. Electrical cabinets usually contain components such as PLC, inverter, contactor, relay, cable and sensor to ensure the stable operation of the system. However, these devices will generate a lot of heat during operation. If the heat cannot be dissipated in time, it may cause the equipment to overheat and affect its performance and life. Therefore, the electrical cabinet needs to adopt a heat dissipation cooling structure.

[0003] The traditional cooling structure of electrical cabinets usually includes a radiator, a fan, and a ventilation system. First, the heat source device inside the electrical cabinet is installed close to the radiator so that the heat can be quickly transferred to the radiator. Then, the cooling air is introduced into the electrical cabinet through the fan and ventilation system, so that the heat can be dissipated to the external environment.

[0004] When the above-mentioned electrical cabinet heat dissipation cooling junction is in use, it only absorbs external air through the radiator and the fan to fan the inside of the electrical cabinet. If the external air is overheated, it is difficult to achieve efficient heat dissipation. At the same time, the heat dissipation distribution is uneven, resulting in poor heat dissipation effect of some structures, which reduces the performance of the equipment or even damages it. At the same time, heat dissipation will drive dust in the air into the interior of the electrical cabinet, affecting the normal operation of the equipment and shortening the service life of the equipment.

[0028] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0029] Reference Figure 1 - Figure 5 The utility model provides an embodiment: a heat dissipation and cooling structure of an electrical component of an electrical cabinet, comprising a cabinet 1, a ventilation component is arranged inside the cabinet 1, a filter bin 2 is fixedly connected to the top of the cabinet 1, a duct 3 is fixedly connected to the top of the filter bin 2, a fan 4 is fixedly connected to the inner wall of the duct 3, a filter cover 5 is threadedly connected to the outer wall of the duct 3, a filter plate 6 is slidably connected to the inside of the filter bin 2, a cooling water pipe 7 is fixedly connected to the inside of the filter bin 2, a shunt pipe 8 is fixedly connected to the bottom of the filter bin 2, and the outer wall of the shunt pipe 8 is fixedly connected to the inside of the cabinet 1 The nozzle 9 is fixedly connected to the inside of the shunt pipe 8, the inside of the filter bin 2 is rotatably connected to the rotating rod 10, one end of the rotating rod 10 is fixedly connected to the block 11, the outer wall of the block 11 is arranged inside the filter plate 6, the outer wall of the rotating rod 10 is fixedly connected to the limit rod 12, the outer wall of the rotating rod 10 is provided with a rotating component, a ventilation component including a ventilation hole 15, the ventilation hole 15 is opened inside the cabinet 1, the inside of the cabinet 1 is fixedly connected to the filter screen 16, the outer wall of the cabinet 1 is provided with a cabinet door 25, and the inside of the cabinet door 25 is provided with the ventilation hole 15 and the filter screen 16;

[0030] Specifically, the fan 4 is first started to introduce external air into the filter chamber 2 through the air duct 3. During this process, the air will first be preliminarily filtered through the filter cover 5. Since the filter cover 5 and the air duct 3 are threadedly connected, it is convenient for the user to remove the filter cover 5 for cleaning by simply turning it, thereby maintaining its filtering effect. The air preliminarily filtered by the filter cover 5 will continue to be further filtered through the filter plate 6 inside the air duct 3. During this process, in order to ensure that the air temperature is not too high, the cooling water inside the cooling water pipe 7 circulates the cooling water between the cooling box and the cooling water pipe 7 through the pipes on both sides. The heat in the air is absorbed for heat exchange, and the air is cooled to ensure that the temperature of the air sent into the cabinet 1 is moderate. The air after cooling and secondary filtration will be evenly discharged into the interior of the cabinet 1 through the shunt pipe 8 and the nozzle 9, thereby achieving the cooling effect. Finally, the preset ventilation holes 15 and the filter 16 inside the cabinet 1 will work together to discharge the cooled and filtered air, ensuring that the electrical components inside the cabinet 1 can operate in a good environment, not only achieving efficient heat dissipation, but also effectively preventing dust and other impurities from damaging the internal electrical components, thereby extending the service life of the equipment.

[0031] Reference Figure 1 , Figure 5 and Figure 6 The rotary assembly includes a torsion spring 13, which is sleeved on the outer wall of the rotating rod 10, one end of the torsion spring 13 is fixedly connected to the inside of the filter bin 2, and the other end of the torsion spring 13 is fixedly connected to a connecting plate 14, and the inside of the connecting plate 14 is fixedly connected to the outer wall of the rotating rod 10;

[0032] Specifically, in order to facilitate cleaning of the filter plate 6, the block 11 can be driven to rotate inside the filter plate 6 by rotating the rotating rod 10. When the block 11 is rotated to a vertical state, the filter plate 6 can be easily taken out for cleaning, thereby ensuring its filtering effect. During the installation process, the rotating rod 10 is first driven. When the rotating rod 10 is rotated to a certain angle, the filter plate 6 can be returned to its original position. At the same time, the torsion spring 13 will be reversed. When the rotating rod 10 is released, the torsion spring 13 starts to rotate, which will drive the block 11 to rotate inside the filter plate 6, fix the filter plate 6, and ensure that it is firmly installed in the correct position. In this process, the rotation of the rotating rod 10 will also drive the limit rod 12 to rotate. In order to prevent the block 11 from rotating excessively, the limit rod 12 slides in a fan-shaped chute preset inside the filter chamber 2. When the block 11 rotates to a certain position, the limit rod 12 will reach its limit position in the fan-shaped chute, thereby preventing the block 11 from continuing to rotate, thereby ensuring that the filter plate 6 is firmly fixed.

[0033] Reference Figure 7 and Figure 8The inner wall of the cabinet 1 is fitted with a mounting plate 17, a fixing bolt 18 is arranged inside the mounting plate 17, the outer wall of the fixing bolt 18 is arranged inside the mounting plate 17, a clamping plate 19 is rotatably connected inside the mounting plate 17, the outer wall of the clamping plate 19 is fixedly connected with a fixing block 20, the fixing block 20 is rotatably connected with a rotating shaft 21, one end of the rotating shaft 21 is fixedly connected with a fixing plate 22, the outer wall of the fixing plate 22 is slidably connected to the outer wall of the fixing block 20, the outer wall of the fixing plate 22 is fixedly connected with a telescopic rod 23, the outer wall of the telescopic rod 23 is sleeved with a telescopic spring 24, and both ends of the telescopic spring 24 are fixedly connected to the outer wall of the fixing plate 22;

[0034] Specifically, firstly, according to the distribution of the wiring harness inside the cabinet 1, the mounting plate 17 and the clamping plate 19 need to be installed in the appropriate position by the fixing bolts 18 to ensure that the mounting plate 17 and the clamping plate 19 can be stably fixed on the cabinet 1. Next, the wiring harness is placed between the two clamping plates 19 one by one. When the wiring harness is placed between the clamping plates 19, a certain pressure is applied to the clamping plates 19, so that the clamping plates 19 rotate to both sides. As the clamping plates 19 rotate, the two fixing blocks 20 on one side will be driven to move relative to each other. When the fixing blocks 20 move, the extension The expansion spring 24 will shrink between the two fixed blocks 20. When the wiring harness is completely moved between the two clamps 19, the expansion spring 24 is no longer under pressure and will rebound. The rebound force will drive one end of the two clamps 19 to fit together again, thereby firmly clamping the wiring harness to prevent it from falling off. The wiring harness inside the cabinet 1 can be centrally organized to make it orderly and not easy to be scattered, which not only improves the aesthetics of the interior of the cabinet 1, but also helps to maintain and manage the wiring harness and reduce malfunctions or safety hazards that may be caused by the confusion of the wiring harness.

[0035] Working principle: When the heat dissipation cooling structure of the electrical components of the electrical cabinet is needed, the fan 4 is first started to send the external air to the inside of the filter bin 2 through the air duct 3. In this process, the filter cover 5 is used for preliminary filtration. At the same time, due to the threaded connection between the filter cover 5 and the air duct 3, the filter cover 5 can be removed for cleaning by rotating it, and then it is further filtered through the filter plate 6 inside the filter bin 2. In this process, the air is cooled by the cooling water inside the cooling water pipe 7, and finally discharged to the inside of the cabinet 1 through the shunt pipe 8 and the nozzle 9 for cooling. Then, the block 11 is driven to rotate inside the filter plate 6 by rotating the rotating rod 10, so that the block 11 rotates to the vertical position. When the filter plate 6 is in the straight state, the filter plate 6 can be taken out for cleaning. When installing, first rotate the rotating rod 10 and then put the filter plate 6 back to its original position. At the same time, the torsion spring 13 is reversed. When the rotating rod 10 is released, the torsion spring 13 rotates back, driving the block 11 to rotate inside the filter plate 6, thereby fixing the filter plate 6. During this process, the rotation of the rotating rod 10 will drive the limit rod 12 to slide in the fan-shaped slide groove preset inside the filter bin 2, thereby preventing the block 11 from rotating excessively. Finally, the preset ventilation holes 15 inside the cabinet 1 cooperate with the filter screen 16 to discharge the air, achieving the effect of efficient heat dissipation while preventing dust from damaging the internal electrical components.

[0036] In addition, according to the distribution of the wiring harness inside the cabinet 1, the mounting plate 17 and the clamping plate 19 are installed in appropriate positions by means of the fixing bolts 18, and then the wiring harness is placed between the two clamping plates 19 and pressed. At this time, the clamping plates 19 rotate to both sides under pressure, thereby driving the two fixed blocks 20 on one side to move relative to each other, and then causing the telescopic spring 24 to contract between the two fixed blocks 20. When the wiring harness is completely moved between the two clamping plates 19, the telescopic spring 24 is no longer subjected to force and rebounds, thereby driving one end of the two clamping plates 19 to fit together again to prevent the wiring harness from falling off, thereby achieving the effect of convenient centralized arrangement of the wiring harness.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
