Description

Technical Field

[0001] The present application relates to the technical field of electrical cabinets, and in particular to a heat dissipation and ventilation structure of an electrical cabinet. Background Art

[0002] The electrical cabinet is a cabinet made of steel, which is mainly used to protect the normal operation of components. It is usually made of metal materials such as steel plates and steel pipes, and is sturdy and durable. The main function of the electrical cabinet is to provide a safe and stable working environment to protect the internal electrical equipment and components from the influence of the external environment.

[0003] An electrical cabinet detection and maintenance device mentioned in an existing Chinese public patent (authorization announcement number: CN219498585U) can fix the temperature control switch, facilitate the disassembly and assembly of the temperature control switch, and facilitate the replacement and maintenance of the temperature control switch. It is simple to operate and easy to use. Through the setting of the reciprocating component, the fixed box can drive the temperature control switch fixed to the front end of the fixed box by the clamping plate to slide up and down, and then the temperature of the electrical components at various positions inside the electrical cabinet can be detected, thereby expanding the detection range of the temperature control switch.

[0004] Most existing electrical cabinets use fans to dissipate heat, thereby ensuring that the electronic components of the electrical cabinet are kept at a suitable and safe temperature. However, the position of the fans inside the existing electrical cabinets is mostly fixed, so the heat dissipation area is limited, which may result in less than ideal heat dissipation effect. Utility Model Content

[0005] The purpose of the present application is to solve the problem that the positions of fans inside existing electrical cabinets are mostly fixed, so the heat dissipation area is limited. The present application provides a heat dissipation and ventilation structure for an electrical cabinet.

[0006] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:

[0007] A heat dissipation and ventilation structure of an electrical cabinet comprises a cabinet body, a cabinet door is hinged on one side of the cabinet body, a control panel is fixedly connected to the top of the cabinet body, an air inlet is opened on the top of the cabinet body, an air outlet is opened on one side of the cabinet body, a filter plate 1 is arranged inside the air outlet, vertical blocks are fixedly connected to the upper and lower sides of the filter plate 1, a fastener is arranged on one side of the vertical block, connecting columns are fixedly connected to the inner top walls on both sides of the cabinet body, a hair dryer is fixedly connected between the connecting columns on both sides, a filtering mechanism is arranged on the top of the cabinet body above the air inlet, and a heat dissipation mechanism is arranged inside the cabinet body.

[0008] By adopting the above technical solution, the hair dryer is started so that the external air is drawn into the interior of the cabinet from the air inlet. The air entering the cabinet exchanges heat with the heat inside the cabinet, takes the heat away, and is finally discharged through the air outlet, thereby completing the heat dissipation inside the cabinet.

[0009] Furthermore, the filtering mechanism includes an air inlet block fixedly connected to the top of the cabinet, the interior of the air inlet block is configured as a through hole, a filter plate 2 is provided inside the air inlet block, one end of the filter plate 2 passes through the air inlet block and is fixedly connected to a handle, and the filter plate 2 is slidably connected to the air inlet block.

[0010] By adopting the above technical solution, the handle is pulled to drive the second filter plate to move, so that the second filter plate is pulled out of the outside of the air inlet for cleaning.

[0011] Furthermore, one end of the second filter plate is fixedly connected with a connecting block, the inner wall of the air inlet block is provided with a positioning groove, and the connecting block is slidably connected to the positioning groove.

[0014] By adopting the above technical solution, when the connecting block moves to the inside of the positioning groove, the connecting block will resist the clamping block, causing the clamping block to move upward, driving the spring to be compressed. After the spring is compressed, elastic potential energy is generated.

[0016] By adopting the above technical solution, the card block and the card slot are both set to be semicircular, so that when the card slot moves, the card block will be lifted up, so that the filter plate 2 can be pulled out, which is convenient for cleaning the filter plate 2.

[0018] By adopting the above technical solution, the driving member drives the mounting block to move inside the long hole, and the movement of the mounting block drives the fan to move, so that the fans on both sides constantly approach and move away from each other. Through the continuous movement of the fans, uniformity and efficiency of heat dissipation inside the cabinet can be achieved.

[0019] Furthermore, the driving member includes a bidirectional threaded rod, both ends of which are rotatably connected to the inner wall of the cavity, a rotating motor is fixedly connected to the top of the cabinet, the rotating motor is electrically connected to the control panel, the output shaft of the rotating motor passes through the cabinet and is fixedly connected to the bidirectional threaded rod, the output shaft of the rotating motor is rotatably connected to the cabinet, and thread blocks are threadedly connected to the outer surfaces of both sides of the bidirectional threaded rod, and one side of the thread block is fixedly connected to the mounting block.

[0020] By adopting the above technical solution, the rotating motor is started, which drives the bidirectional threaded rod to rotate. The threaded block is threadedly connected to the bidirectional threaded rod, so that the threaded blocks on both sides approach each other or move away from each other. The threaded block will drive the mounting block to move during the movement.

[0021] Furthermore, an auxiliary rod is arranged inside the cavity, two ends of the auxiliary rod are fixedly connected to the inner wall of the cavity, and the outer surface of the auxiliary rod is slidably connected to the threaded block.

[0022] By adopting the above technical solution, the auxiliary rod is slidably connected to the threaded block, and the auxiliary rod provides a guiding function for the threaded block, so that the movement of the threaded block is more stable.

[0023] In summary, the present application includes at least one of the following beneficial effects:

[0024] 1. In the present application, the uniformity and efficiency of heat dissipation inside the cabinet can be achieved through the continuous movement of the fan. The airflow generated by the continuous movement of the fan can quickly disperse the heat to the entire interior of the electrical cabinet, thereby reducing the temperature of the electronic components and improving their stability and life.

[0033] The following is combined with Figures 1 to 5 This application is described in further detail.

[0034] An embodiment of the present application discloses a heat dissipation and ventilation structure of an electrical cabinet.

[0035] Reference Figure 1 and Figure 2 A heat dissipation and ventilation structure of an electrical cabinet comprises a cabinet body 1, a cabinet door 2 is hinged on one side of the cabinet body 1, a control panel 3 is fixedly connected to the top of the cabinet body 1, an air inlet 4 is opened on the top of the cabinet body 1, an air outlet 5 is opened on one side of the cabinet body 1, a filter plate 23 is arranged inside the air outlet 5, vertical blocks 24 are fixedly connected to the upper and lower sides of the filter plate 23, a fastener is arranged on one side of the vertical block 24, connecting columns 6 are fixedly connected to the inner top walls on both sides of the cabinet body 1, a hair dryer 7 is fixedly connected between the connecting columns 6 on both sides, a filtering mechanism is arranged on the top of the cabinet body 1 above the air inlet 4, and a heat dissipation mechanism is arranged inside the cabinet body 1.

[0036] When too much heat is generated inside the electrical cabinet, the hair dryer 7 is started so that the external air is drawn into the cabinet 1 from the air inlet 4. The air entering the cabinet 1 exchanges heat with the heat inside the cabinet 1, takes the heat away, and is finally discharged through the air outlet 5, thereby completing the heat dissipation inside the cabinet 1. When the external air enters the air outlet 5, the air entering the cabinet 1 is filtered by the filtering mechanism, thereby reducing the risk of dust entering the cabinet 1. When the interior of the cabinet 1 is cooled, the heat dissipation effect is further improved by the heat dissipation mechanism, thereby ensuring that the electronic components inside the cabinet 1 are at a suitable temperature to work.

[0037] Reference Figure 2 , Figure 3 and Figure 4 The filtering mechanism includes an air inlet block 8 fixedly connected to the top of the cabinet 1, the interior of the air inlet block 8 is arranged in a through hole shape, a filter plate 29 is arranged inside the air inlet block 8, one end of the filter plate 29 passes through the air inlet block 8 and is fixedly connected with a handle 10, and the filter plate 29 is slidably connected to the air inlet block 8.

[0038] Among them, one end of the filter plate 2 9 is fixedly connected with a connecting block 11, and the inner wall of the air inlet block 8 is provided with a positioning groove, and the connecting block 11 is slidably connected with the positioning groove.

[0039] In addition, an empty slot 12 is provided on the inner top wall of the positioning slot, and a spring telescopic rod 13 is arranged inside the empty slot 12. The top end of the spring telescopic rod 13 is fixedly connected to the inner wall of the empty slot 12, and the bottom end of the spring telescopic rod 13 is fixedly connected to a clamping block 14, and a clamping slot is provided on the top of the connecting block 11.

[0040] In addition, the card block 14 and the card slot are both configured in a semicircular shape, the card block 14 matches the shape of the card slot, and the card block 14 is engaged and connected with the card slot.

[0041] When external air enters the interior of the cabinet 1, the incoming air is filtered by the filter plate 29. After long-term use, the filter plate 29 is moved by pulling the handle 10, so that the filter plate 29 is taken out for cleaning. When the filter plate 29 is pulled out for cleaning, the card block 14 is set to a semicircular shape, and the card slot is also set to a semicircular shape, so that the card block 14 will be lifted up when the card slot moves, so that the filter plate 29 can be pulled out. After cleaning, the filter plate 29 is placed inside the air inlet block 8. At this time, the positioning function of the positioning groove allows the filter plate 29 to be placed in the correct The position is convenient for use. When the connecting block 11 moves to the inside of the positioning groove, the connecting block 11 will resist the card block 14, so that the card block 14 moves upward, driving the spring to be compressed. After the spring is compressed, elastic potential energy is generated. When the card block 14 moves to the card slot, the elastic potential energy of the spring is released, so that the card block 14 and the card slot are connected in a card-engaging manner, thereby fixing the filter plate 29, making the disassembly and cleaning of the filter plate 29 simple and convenient, thereby reducing the risk of filter plate clogging and improving the efficiency of air passing through the filter plate 29, so that the heat dissipation effect inside the cabinet 1 is better.

[0042] Reference Figure 2 and Figure 5 The heat dissipation mechanism includes a cavity 22 opened inside the cabinet 1, and mounting blocks 18 are slidably arranged on both sides of the cavity 22. A long hole 19 is opened on one side of the cavity 22. The mounting block 18 is slidably connected to the long hole 19. A fan 20 is fixedly connected to one end of the mounting block 18 away from the cavity 22. The fan 20 is electrically connected to the control panel 3, and a driving member is arranged on the outer surface of the mounting block 18.

[0043] Among them, the driving part includes a bidirectional threaded rod 16, both ends of which are rotatably connected to the inner wall of the cavity 22, a rotating motor 15 is fixedly connected to the top of the cabinet 1, the rotating motor 15 is electrically connected to the control panel 3, the output shaft of the rotating motor 15 passes through the cabinet 1 and is fixedly connected to the bidirectional threaded rod 16, the output shaft of the rotating motor 15 is rotatably connected to the cabinet 1, and the outer surfaces of both sides of the bidirectional threaded rod 16 are threadedly connected to threaded blocks 17, and one side of the threaded block 17 is fixedly connected to the mounting block 18.

[0044] In addition, an auxiliary rod 21 is disposed inside the cavity 22 , both ends of the auxiliary rod 21 are fixedly connected to the inner wall of the cavity 22 , and the outer surface of the auxiliary rod 21 is slidably connected to the threaded block 17 .

[0045] When the interior of the cabinet 1 is to be cooled, the rotating motor 15 is started, and the rotating motor 15 drives the bidirectional threaded rod 16 to rotate, and the threaded block 17 is threadedly connected to the bidirectional threaded rod 16, so that the threaded blocks 17 on both sides are close to or away from each other. During the movement, the threaded block 17 drives the mounting block 18 to move inside the long hole 19, and the movement of the mounting block 18 drives the fan 20 to move, so that the fans 20 on both sides are constantly close to and away from each other. Through the continuous movement of the fan 20, the uniformity and efficiency of the heat dissipation inside the cabinet 1 can be achieved. The airflow generated by the continuous movement of the fan 20 can quickly disperse the heat to the entire electrical cabinet, thereby reducing the temperature of the electronic components and improving their stability and life. At the same time, when the threaded block 17 moves, it is slidably connected to the threaded block 17 through the auxiliary rod 21. The auxiliary rod 21 provides an additional support point for the threaded block 17, making the threaded block 17 more stable when moving.

[0046] Working principle: When too much heat is generated inside the cabinet 1, start the hair dryer 7 so that the external air is drawn into the cabinet 1 from the air inlet 4 by traction. The air entering the cabinet 1 exchanges heat with the heat inside the cabinet 1, takes the heat away, and is finally discharged through the air outlet 5, thereby completing the heat dissipation inside the cabinet 1. When the external air enters the cabinet 1, the incoming air is filtered by the filter plate 9. After long-term use, the filter plate 9 is moved by pulling the handle 10 to remove and clean the filter plate. After cleaning, when the filter plate is placed in the air inlet block 8, it will resist the card block 14, causing the card block 14 to move upward, driving the spring to be compressed. After the spring is compressed, elastic potential energy is generated. When the card block 14 moves to the card slot, the elastic potential energy of the spring is released, so that the card block 14 and the card slot are connected in a card-engaged manner, thereby fixing the filter plate.

[0047] When the interior of the electrical cabinet is cooled, the rotating motor 15 is started, and the rotating motor 15 drives the bidirectional threaded rod 16 to rotate. The threaded block 17 is threadedly connected to the bidirectional threaded rod 16, so that the threaded blocks 17 on both sides are close to or away from each other. During the movement of the threaded block 17, the mounting block 18 is driven to move inside the long hole 19, and the movement of the mounting block 18 drives the fan 20 to move, so that the fans 20 on both sides are constantly close to and away from each other. Through the continuous movement of the fan 20, the uniformity and efficiency of the heat dissipation inside the cabinet 1 can be achieved, and the airflow generated by the continuous movement of the fan 20 can quickly disperse the heat to the entire cabinet 1.
