Description

A heat dissipation device for a generator set shaft system cabinet

Technical Field

This utility model belongs to the field of heat dissipation technology, specifically relating to a heat dissipation device for a unit shaft system cabinet.

Background Technology

Currently, in the electrical equipment workshops of chemical production facilities, there are numerous unit shaft system cabinets. The electrical equipment housed within these cabinets is the core equipment of the production unit's control system, and its proper operation is crucial to the safe and stable operation of the corresponding production unit. However, these electrical devices typically generate heat during operation. If this heat is not dissipated in a timely manner, it can easily lead to overheating and malfunctions of the corresponding electronic components, which is even more serious in summer when the external ambient temperature is high, posing a significant hazard to safe production. Therefore, heat dissipation for the unit shaft system cabinets is particularly important. The current conventional practice is to install an intake fan at the bottom of the cabinet and an exhaust fan at the top, blowing external air in from the bottom of the cabinet to cool the electrical equipment before exhausting it from the top. However, in practical applications, it has been found that while the intake fan draws in external air, it also brings in external dust and other debris into the cabinet, making cleaning difficult and potentially causing short circuits in electrical components. This is detrimental to the long-term stable operation of the electrical equipment inside the cabinet and requires improvement.

Utility Model Content

In view of this, the purpose of this utility model is to provide a heat dissipation device for the unit shaft system cabinet, which can achieve air intake and dust removal through a dust collector that is easy to disassemble and replace, so as to solve the above problems.

To achieve the above objectives, the technical solution adopted by this utility model is as follows: a heat dissipation device for a generator shaft system cabinet, comprising a cabinet body, the front of which is open and closable and connected to a cabinet door; a plurality of support mesh frames arranged vertically and horizontally fixed inside the cabinet body; a plurality of air inlets arranged in a rectangular array and spaced apart fixedly connected to the bottom of the cabinet body; and a plurality of exhaust pipes arranged in a rectangular array and spaced apart fixedly connected to the top of the cabinet body. Both the top and bottom of the air inlets and exhaust pipes are open, with an intake fan installed inside the air inlet and an exhaust fan installed inside the exhaust pipe. The air outlet direction of both the intake and exhaust fans is upward. A square fixing plate is fixedly sleeved on the lower outer side of the air inlet; positioning grooves are provided on the left and right sides of the bottom of the fixing plate, and motors are built into the front and rear sides. The output shaft of the motor extends downward and is fixed. A limiting block is fixedly connected to the plate. A dust collector is provided below the air inlet cylinder. The top and bottom of the dust collector are open, and an inverted cone hopper is fixedly installed inside the upper part. A cylindrical pleated filter element is fixedly connected to the bottom of the inverted cone hopper. The bottom of the pleated filter element is closed, and the top is connected to the inverted cone hopper. Several mesh discs are fixedly arranged vertically and interspersed inside the inverted cone hopper. Activated carbon is filled between adjacent mesh discs. A square mounting plate is fixedly sleeved on the upper outer side of the dust collector. Positioning blocks are fixed on the left and right sides of the top of the mounting plate, and through slots are opened on the front and back sides. The dust collector abuts against the bottom of the air inlet cylinder, and the mounting plate abuts against the bottom of the fixed plate. The positioning blocks correspond to and are inserted into the positioning slots on the same side. The limiting block passes through the through slots on the same side and abuts against the bottom of the mounting plate after rotating 90 degrees.

Preferably, the mounting plate is adapted to the fixing plate.

Preferably, the positioning block is adapted to the corresponding positioning groove.

Preferably, the cross-sectional area of the through groove is larger than the cross-sectional area of the limiting block.

Preferably, a dustproof net is fixedly installed inside the upper part of the exhaust pipe.

Preferably, a limit switch is provided on the front side of the top of the cabinet, and several lights are provided on the top and inner side of the cabinet. A controller is provided on the outer side of the cabinet, and the air intake fan, exhaust fan, motor, limit switch and lights are all electrically connected to the controller.

The beneficial effects of this utility model are as follows: During use, external air can be blown in from the bottom of the cabinet by the intake fan to cool the electrical equipment, and then exhausted from the top of the cabinet by the exhaust fan, achieving effective heat dissipation inside the cabinet. During air intake, under the blowing of the intake fan, external air can first pass through the pleated filter element from the outside to the inside, and then pass through multiple layers of activated carbon from bottom to top. Thus, with the cooperation of the pleated filter element and multiple layers of activated carbon, the intake external air can be effectively intercepted, filtered, and purified multiple times, which can greatly improve the cleanliness of the intake air, thereby reducing the adverse effects of dust on the electrical equipment inside the cabinet and promoting the long-term stable operation of the electrical equipment inside the cabinet. After a period of use, the dust collector can be disassembled and replaced. Specifically, in the stopped state, first run the motor to drive the limit block to rotate 90 degrees, so that the limit block is aligned with the corresponding through slot, thereby releasing the pressure limit on the mounting plate. Then pull out the positioning block to remove the original dust collector. Next, after taking the new dust collector cylinder, align it and place it against the bottom of the air inlet cylinder. Simultaneously, align the mounting plate and place it against the bottom of the fixing plate. At this point, the positioning block can be aligned and inserted into the corresponding positioning groove, and the limiting block can penetrate the corresponding through groove to the bottom of the mounting plate, achieving initial positioning and installation of the dust collector cylinder. Then, run the motor again, driving the limiting block to rotate 90 degrees. This will cause the limiting block to displace from the corresponding through groove and press against the corresponding position on the bottom of the mounting plate, achieving pressure and limiting of the mounting plate. This completes the fixed installation of the entire dust collector cylinder, ensuring a stable installation for subsequent use. This allows for convenient disassembly and replacement of the dust collector cylinder, and further ensures the dust removal and purification effect on the drawn-in air during air intake, making the overall device more convenient and practical.

Detailed Implementation

The present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments:

As shown in Figures 1 to 10, a heat dissipation device for a generator shaft system cabinet includes a cabinet 1. The front of the cabinet 1 is open and closable, with a cabinet door 2 for opening and closing the cabinet 1. The specific method and structure of the closable connection can be achieved using existing technology and will not be detailed here. Several support frames 3, spaced vertically, are fixed inside the cabinet 1 for mounting and supporting corresponding electrical equipment.

The bottom of the cabinet 1 is fixedly connected to several air inlets 4 arranged in a rectangular array at intervals, and the top is fixedly connected to several exhaust pipes 5 arranged in a rectangular array at intervals. Both the top and bottom of the air inlets 4 and exhaust pipes 5 are open, and an air intake fan 6 is installed inside the air inlet 4 and an exhaust fan 7 is installed inside the exhaust pipe 5. The air outlet direction of the air intake fan 6 and the exhaust fan 7 is upward. A square fixing plate 8 is fixedly sleeved on the lower outer side of the air inlet 4. Positioning grooves 9 are opened on the left and right sides of the bottom of the fixing plate 8, and motors 10 are built into the front and rear sides. The output shaft of the motor 10 extends downward out of the fixing plate 8 and is fixedly connected to a limit block 11. Below the air inlet cylinder 4 is a dust collector cylinder 12. The top and bottom of the dust collector cylinder 12 are open, and an inverted cone hopper 13 is fixedly installed inside the upper part. A cylindrical pleated filter element 14 is fixedly connected to the bottom of the inverted cone hopper 13. The bottom of the pleated filter element 14 is closed, and the top is connected to the inverted cone hopper 13. Several mesh discs 15 are fixedly installed inside the inverted cone hopper 13 at intervals. Activated carbon 16 is filled between two adjacent mesh discs 15. A square mounting plate 17 is fixedly sleeved on the upper outer side of the dust collector cylinder 12. Positioning blocks 18 are fixed on the left and right sides of the top of the mounting plate 17, and through slots 19 are opened on the front and rear sides. The dust collector cylinder 12 abuts against the bottom of the air inlet cylinder 4, and the mounting plate 17 abuts against the bottom of the fixed plate 8. The positioning blocks 18 correspond to and are inserted into the positioning slots 9 on the same side. The limiting block 11 passes through the through slots 19 on the same side and abuts against the bottom of the mounting plate 17 after rotating 90 degrees.

In use, external air can be blown in from the bottom of the cabinet 1 by the intake fan 6 to cool the electrical equipment, and then exhausted from the top of the cabinet 1 by the exhaust fan 7, achieving effective heat dissipation inside the cabinet 1. During air intake, under the blowing of the intake fan 6, external air can first pass through the pleated filter element 14 from the outside to the inside, and then pass through the multi-layer activated carbon 16 from bottom to top. Thus, with the cooperation of the pleated filter element 14 and the multi-layer activated carbon 16, the intake external air can be effectively intercepted, filtered, and purified multiple times, which can greatly improve the cleanliness of the intake air, thereby reducing the adverse effects of dust on the electrical equipment inside the cabinet 1 and promoting the long-term stable operation of the electrical equipment inside the cabinet 1. After a period of use, the dust collector 12 can be disassembled and replaced. Specifically, in the stopped state, first run the motor 10 to rotate the limit block 11 90 degrees, so that the limit block 11 is aligned with the corresponding through groove 19, thereby releasing the pressure limit on the mounting plate 17. Then pull out the positioning block 18 to remove the original dust collector 12. Next, after taking the new dust collector 12, first align it and abut it against the bottom of the air inlet 4, and at the same time align the mounting plate 17 and abut it against the bottom of the fixing plate 8. At this time, the positioning block 18 can be aligned and inserted into the corresponding positioning groove 9, and the limit block 11 can pass through the corresponding through groove 19 to the bottom of the mounting plate 17 to achieve the initial positioning and installation of the dust collector 12. Then, the motor 10 is run again, driving the limiting block 11 to rotate 90 degrees. This causes the limiting block 11 to be misaligned with the corresponding through slot 19 and press against the corresponding position on the bottom of the mounting plate 17, thus achieving pressure and limiting of the mounting plate 17. This completes the fixed installation of the entire dust collector 12, ensuring a stable installation and guaranteeing subsequent use. This allows for convenient disassembly and replacement of the dust collector 12, and further ensures the dust removal and purification effect on the drawn-in air during air intake, making the overall device more convenient and practical. Both the intake fan 6 and the exhaust fan 7 can use existing technology. The motor 10 can specifically be a conventional stepper motor with a brake function to achieve the corresponding angle of rotation and position locking after rotation.

In this embodiment, the mounting plate 17 is adapted to the fixing plate 8 to ensure that the mounting plate is smoothly installed in place.

In this embodiment, the positioning block 18 is adapted to the corresponding positioning groove 9 to ensure that the positioning block 18 is smoothly inserted and installed in place.

In this embodiment, the cross-sectional area of the through groove 19 is larger than the cross-sectional area of the limiting block 11, so as to ensure that the limiting block 11 can pass smoothly through the through groove 19.

In this embodiment, a dustproof net 20 is fixedly installed inside the upper part of the exhaust pipe 5 to prevent external dust and other debris from entering the cabinet 1 from the exhaust pipe.

In this embodiment, a limit switch 21 is provided on the front side of the top of the cabinet 1. Several lights 22 are provided on the inner top and inner side of the cabinet 1. A controller 23 is provided on the outer side of the cabinet 1. The intake fan 6, exhaust fan 7, motor 10, limit switch 21, and lights 22 are all electrically connected to the controller 23. In actual use, after the cabinet door 2 is closed, the limit switch 21 can be pressed down. After the limit switch 21 is pressed down, it feeds back to the controller 23. The controller 23 can automatically control the lights 22 to turn off and automatically control the intake fan 6 and exhaust fan 7 to turn on for heat dissipation. When it is necessary to repair the electrical equipment inside the cabinet 1, the cabinet door 2 is opened, the limit switch 21 is reset, and it feeds back to the controller 23 again. The controller 23 can then automatically control the intake fan 6 and exhaust fan 7 to turn off heat dissipation and automatically control the lights 22 to turn on, thus facilitating maintenance operations and making the device more practical. The limit switch 21, lights 22, and controller 23 can all use existing technology.

The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
