Description

Technical Field

[0001] The present invention relates to the technical field of electrical cabinets for chemical fiber production, and particularly relates to an electrical cabinet with good protection and heat dissipation performance. Background Art

[0002] Due to the particularity of the chemical fiber filament production process, the environment in the chemical fiber filament production workshop has the characteristics of high temperature and high oil vapor content compared with the ordinary factory environment. The chemical fiber bobbin-changing robot is a key equipment in the chemical fiber filament production process. Since this equipment is always in a moving state on the track, at present, the water-cooling system generally applicable to harsh environments cannot be applied to the electrical cabinet of the bobbin-changing robot. When an ordinary electrical cabinet body works in such an environment for a long time, it cannot dissipate heat well, which affects the normal performance of components. At the same time, the oil in the air will liquefy on the components and at the cable joints, endangering the operation and service life of the electrical equipment. This puts forward higher requirements for heat dissipation and protection for the electrical cabinets used in such an environment. Summary of the Invention

[0003] In view of this, the present invention provides an electrical cabinet with good protection and heat dissipation performance, which has an air heat exchanger. The hot air exchanges heat with the air outside the electrical cabinet for heat dissipation transmitted from the external circulation filter, taking away the heat inside the electrical cabinet of the components.

[0004] The present invention provides an electrical cabinet with good protection and heat dissipation performance, specifically including: an electrical cabinet for components; the front end position of the electrical cabinet for components is fixedly connected to the rear end position of the electrical cabinet for heat dissipation, and a steel plate is used for sealing between the electrical cabinet for heat dissipation and the electrical cabinet for components. Installation holes are respectively opened at the upper and lower ends of the fitting position between the electrical cabinet for heat dissipation and the electrical cabinet for components. An internal circulation intake fan is installed in the upper installation hole, and an internal circulation exhaust fan is installed in the lower installation hole.

[0005] Optionally, an external circulation exhaust fan is arranged above the front end of the electrical cabinet for heat dissipation, and an external circulation filter is arranged below the front end of the electrical cabinet for heat dissipation. The external circulation exhaust fan is located directly above the external circulation filter.

[0006] Optionally, an air heat exchanger is arranged at the middle position inside the electrical cabinet for heat dissipation. The hot air inlet of the air heat exchanger is connected to the internal circulation intake fan, the hot air outlet is connected to the internal circulation exhaust fan, and the cold air outlet of the air heat exchanger is connected to the air outside the electrical cabinet for heat dissipation through the external circulation exhaust fan. All of the above are connected through a sealed air duct.

[0007] Optionally, an internal circulation oil filter and an air temperature and pressure sensor are arranged at the internal circulation exhaust air duct of the air heat exchanger.

[0008] Optionally, an electrical cabinet door is provided at the left position of the component electrical cabinet, and an oil-proof sealing strip is used at the connection position between the electrical cabinet door and the component electrical cabinet to prevent oil vapor in the air from entering the cabinet body. A cable inlet and outlet is provided at the middle position of the rear end inside the component electrical cabinet, and a rubber through-board device is installed here to ensure the protection level requirements of the cabinet body.

[0009] Optionally, a support frame is provided at the middle position of the rear end of the component electrical cabinet. Chutes are provided on both side rods at the rear end of the support frame. A reversing gear is rotatably connected in each chute of the support frame. A force-changing plate is slidably connected to the inner side position of the chute of the component electrical cabinet. The racks on both sides of the force-changing plate are respectively engaged with the two reversing gears. The front end of the force-changing plate is in contact with the rear end of the cable inlet and outlet.

[0010] Optionally, the outer side position of the chute of the support frame is slidably connected to the two racks of the force-bearing plate, and the racks of the force-bearing plate are respectively engaged with the two reversing gears. The force-bearing plate is located directly behind the force-changing plate. Elastic cushions are respectively connected to the front end positions of the two racks of the force-bearing plate. The elastic cushions are designed in a segmented manner. The other ends of the two elastic cushions are in contact with the rear end position of the support frame.

[0011] Beneficial effects

[0012] According to the air heat exchangers of the embodiments of the present invention, compared with the traditional ones, the hot air inlet of the air heat exchanger is connected to the inner circulation intake fan, the hot air outlet is connected to the inner circulation exhaust fan, and the cold air outlet of the air heat exchanger is connected to the air outside the heat dissipation electrical cabinet through the outer circulation exhaust fan. And it has good heat dissipation effect, is suitable for relatively high-temperature environments such as chemical fiber manufacturing workshops, does not need to be connected to pipelines such as compressed air and cooling water, is particularly suitable for the application of mobile devices, avoids the problem that the water cooling system cannot be applied to the electrical cabinet of the doffing robot, and has a simple structure, is easy to control costs, and is convenient for maintenance.

[0013] In addition, near the inner circulation oil filter, an air temperature and pressure sensor is installed and connected to the control system of the device, which can monitor the working state of the entire circulation system. If there are situations such as a decrease in air pressure caused by a blockage of the air heat exchanger or the filter screen, or a rise in air temperature caused by poor heat exchange effect, an alarm will be given in time to avoid damage to the components inside the component electrical cabinet.

[0014] In addition, the cabinet where the electrical components are located is isolated from the air containing oil vapor outside, preventing device hazards caused by the accumulation of oil and other harmful substances on the electrical components. At the same time, an oil filter is installed on the internal circulation air duct to remove a small amount of oil vapor that enters the cabinet due to maintenance and other reasons.

[0031] In addition, according to an embodiment of the present invention, as Figure 4 shown: An external circulation exhaust fan 6 is arranged at the upper front position of the heat dissipation electrical cabinet 2, an external circulation filter 7 is arranged at the lower front position of the heat dissipation electrical cabinet 2, and the external circulation exhaust fan 6 is located directly above the external circulation filter 7.

The hot air inlet of the air heat exchanger 8 is connected to the internal circulation intake fan 4, and the hot air outlet is connected to the internal circulation exhaust fan 5.

[0032] In addition, according to an embodiment of the present invention, as Figure 4 shown: The cold air outlet of the air heat exchanger 8 is connected to the air outside the heat dissipation electrical cabinet 2 through the external circulation exhaust fan 6. An internal circulation oil filter 10 and an air temperature and pressure sensor 11 are arranged at the internal circulation exhaust air duct of the air heat exchanger 8.

[0033] In addition, according to an embodiment of the present invention, as Figure 4 shown: An electrical cabinet door 3 is arranged at the left side position of the component electrical cabinet 1, and an oil-proof sealing strip is used at the connection position between the electrical cabinet door 3 and the component electrical cabinet 1. A cable inlet and outlet 9 is arranged at the middle position of the inner rear end of the component electrical cabinet 1.

[0034] Specific usage method and function of this embodiment: In the present invention,

[0035] During the use of the electrical cabinet, the component electrical cabinet 1 and the electrical cabinet door 3 are in the closed state. The air inside the component electrical cabinet 1, carrying the heat dissipated by the components, enters the internal position of the heat dissipation electrical cabinet 2 through the 4 internal circulation intake fans, and enters the air heat exchanger 8 through the air duct;

[0036] In the air heat exchanger 8, the hot air exchanges heat with the air outside the heat dissipation electrical cabinet 2 transmitted from the external circulation filter 7, and the heat is taken away, achieving a cooling effect;

[0037] After the temperature drops, it is discharged from the exhaust port of the air heat exchanger 8, enters the internal circulation oil filter 10, filters out a small amount of oil vapor that enters the component electrical cabinet 1 due to door opening maintenance or other reasons, and then enters the component electrical cabinet 1 through the internal circulation exhaust fan 5, completing one cycle.

[0038] The air containing oil vapor outside the cabinet that enters the air heat exchanger 8 from the external circulation filter 7, after taking away the heat of the internal circulation air, is discharged outside the cabinet by the external circulation exhaust fan 6, completely isolated from the air inside the component electrical cabinet 1, and will not affect the use of the components inside the component electrical cabinet 1.

[0039] In addition, near the internal circulation oil filter 10, an air temperature and pressure sensor 11 is installed and connected to the control system of the device, which can monitor the working state of the entire circulation system. If there are situations such as a decrease in air pressure caused by blockage of the air heat exchanger 8 or the filter screen, or an increase in air temperature due to poor heat exchange effect, an alarm will be given in a timely manner to avoid damage to the components inside the component electrical cabinet 1.

[0040] In addition, since the front end of the force conversion plate 103 fits with the rear end of the cable inlet and outlet 9, and a spring pad is elastically connected to the front end positions of the two racks of the force receiving plate 104 respectively. The spring pad is designed in a segmented manner, and the other ends of the two spring pads fit with the rear end position of the support frame 101. When the force receiving plate 104 moves forward under force, the force receiving plate 104 drives the force conversion plate 103 to move backward through the cooperation of the two reversing gears 102, disengaging from the fit with the rear end of the cable inlet and outlet 9, providing a reverse thrust when the force receiving plate 104 is under force, avoiding the cable connected to the cable inlet and outlet 9 from being damaged due to force, and at the same time achieving a dust-proof effect on the cable inlet and outlet 9.

[0041] Finally, it should be noted that when describing the positions of various components and their cooperation relationships, etc., usually one / a pair of components are taken as examples. However, those skilled in the art should understand that such positions, cooperation relationships, etc. also apply to other components / other pairs of components.

[0042] The above are only exemplary embodiments of the present invention and are not intended to limit the scope of protection of the present invention, which is determined by the appended claims.
