Description

Technical Field

[0001] The present invention relates to the technical field of elevator control cabinets, and particularly to an elevator control cabinet with a novel heat dissipation structure. Background Art

[0002] An elevator control cabinet is an important part of an elevator system. It is a cabinet equipped with electrical equipment and control components for controlling and managing the operation of an elevator. Depending on the type and scale of different elevators, its structure, size, and configuration may vary. It is usually designed and manufactured by professional elevator manufacturers according to relevant safety standards and specifications. The reliability and performance of the elevator control cabinet are crucial for the safe and normal operation of the elevator. Therefore, regular maintenance and inspection are necessary. Generally, a large number of electrical components are integrated in the elevator control cabinet. Therefore, during the operation and control of the elevator, a large amount of heat is often generated. Therefore, heat dissipation windows and heat dissipation fans are usually equipped on the elevator control cabinet to dissipate heat inside the cabinet.

[0003] However, the existing heat dissipation methods for elevator control cabinets have the following problems: The conventional heat dissipation methods using heat dissipation windows or heat dissipation fans can achieve a certain heat dissipation purpose for the inside of the elevator cabinet. However, due to the relatively concentrated electrical appliances inside the cabinet, the electrical appliances located inside often do not receive good heat dissipation treatment. And when the staff repairs the cabinet, when the cabinet door is opened, the air flow disturbance inside is likely to cause external pollutants to enter, which further poses a hidden danger of affecting the normal operation of the internal electrical components. Therefore, corresponding technical solutions need to be designed to solve the existing technical problems. Summary of the Invention

[0004] The purpose of the present invention is to provide an elevator control cabinet with a novel heat dissipation structure, which solves the technical problem that the conventional heat dissipation methods using heat dissipation windows or heat dissipation fans can achieve a certain heat dissipation purpose for the inside of the elevator cabinet, but due to the relatively concentrated electrical appliances inside the cabinet, the electrical appliances located inside often do not receive good heat dissipation treatment, and when the staff repairs the cabinet, when the cabinet door is opened, the air flow disturbance inside is likely to cause external pollutants to enter, which further poses a hidden danger of affecting the normal operation of the internal electrical components.

[0005] To achieve the above object, the present invention provides the following technical solution: An elevator control cabinet with a novel heat dissipation structure, comprising an elevator control cabinet body, a pull-out heat dissipation component, a horizontal regulator, floating heat dissipation fins, and an inner wall heat dissipation pipeline. The elevator control cabinet body includes a cabinet, a partition board, and a cabinet door. A guiding groove is longitudinally opened inside the cabinet. The partition boards are divided into two groups and symmetrically installed in the middle of the cabinet. The two groups of partition boards form two installation grooves inside the cabinet, and a pull-out groove is formed between the two groups of partition boards. An air inlet is opened on one side of the pull-out groove, and a compressor is installed below the air inlet. The cabinet door is movably installed on one side of the cabinet, and a number of push rods are symmetrically installed in the middle. The pull-out heat dissipation component is movably arranged in the pull-out groove and includes a pull-out plate with an inner cavity formed therein and an induced draft fan installed on one side of the pull-out plate. A number of sockets are symmetrically opened at the outer end of the pull-out plate, and a number of horizontal regulators are respectively connected to the inner sides of the number of sockets. The inner ends of the number of horizontal regulators are connected to a moving plate, which is located below the guiding groove. A number of movable openings are evenly opened on the surface of the partition board, and a number of floating heat dissipation fins are evenly inserted into the number of movable openings. The floating heat dissipation fins are connected to the compressor through a pipeline. The inner wall heat dissipation pipeline is composed of a number of shunt heat dissipation pipes, and the number of shunt heat dissipation pipes are evenly installed on the inner wall of the installation groove and communicated with the guiding groove.

[0006] As a preferred embodiment of the present invention, the horizontal regulator includes a push plate, a column, and a return spring. The end of the push plate is located inside the socket and is connected to the column at the bottom. The column is connected to the return spring, and the end of the return spring is fixed inside the inner cavity.

[0007] As a preferred embodiment of the present invention, a number of convex balls are fixed on both the upper and lower surfaces of the push plate, and the convex balls are used in cooperation with the floating heat dissipation fins.

[0008] As a preferred embodiment of the present invention, the moving plate includes a plate body and a floating ball fixed on the outer side of the plate body. The floating ball has a spherical structure, and a horizontal plate is arranged above it. Two vertical plates are symmetrically installed at the upper end of the horizontal plate, and a number of blocking pieces are evenly installed on the vertical plates. The blocking pieces are used in cooperation with the shunt heat dissipation pipes.

[0009] As a preferred embodiment of the present invention, the shunt heat dissipation pipe includes a pipe body and a number of exhaust holes evenly opened on the surface of the pipe body, and the pipe body is fixed on the inner wall of the installation groove.

[0010] As a preferred embodiment of the present invention, the floating heat sink includes an air inlet hood, a flow dividing plate, a top plate, an air guiding port and an exhaust port.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] 1. The present invention designs a component for efficiently cooling an elevator control cabinet. The high-efficiency cooling elevator control cabinet includes an elevator control cabinet body, a pull-out heat dissipation component, a horizontal regulator, a floating heat sink and an inner wall heat dissipation pipeline. When it is necessary to dissipate heat from the components inside the elevator control cabinet body, the pull-out heat dissipation component is used to dissipate heat inside the cabinet body. The cooling air flow dissipates heat from the components in all directions along the floating heat sink and the inner wall heat dissipation pipeline. And when the staff needs to open the elevator cabinet for maintenance, the cabinet door is opened, at this time the horizontal regulator moves outwards and closes the air flow channel, thereby stopping the air flow disturbance inside the cabinet and reducing the entry of dust in the external environment into the cabinet body.

Specific embodiments

[0022] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0023] Please refer to Figures 1-5 , the present invention provides a technical solution: an elevator control cabinet with a novel heat dissipation structure, including an elevator control cabinet body, a pull-out heat dissipation component, a horizontal regulator, a floating heat dissipation fin and an inner wall heat dissipation pipeline. The elevator control cabinet body includes a cabinet body 1, a partition board 2, a cabinet door 3 and a plug rod 4. A guiding groove 5 is longitudinally opened inside the cabinet body 1. There are two groups of partition boards 2 and they are symmetrically installed in the middle of the cabinet body 1. The two groups of partition boards 2 form two installation grooves 6 inside the cabinet body 1. A pulling groove 7 is formed between the two groups of partition boards 2. An air inlet 8 is opened on one side of the pulling groove 7. A compressor 9 is installed below the air inlet 8. The cabinet door 3 is movably installed on one side of the cabinet body 1 and a number of push rods 10 are symmetrically installed in the middle. The pull-out heat dissipation component is movably arranged in the pulling groove 7 and includes a pulling plate 12 with an inner cavity 11 formed inside and an induced draft fan 13 installed on one side of the pulling plate 12. A number of sockets 14 are symmetrically opened at the outer end of the pulling plate 12. The inner sides of the number of sockets 14 are respectively connected to a number of horizontal regulators. The inner ends of the number of horizontal regulators are connected to a moving plate 15. The moving plate 15 is located below the guiding groove 5. A number of movable openings 16 are evenly opened on the surface of the partition board 2. A number of floating heat dissipation fins are evenly inserted into the number of movable openings 16. The floating heat dissipation fins are connected to the compressor 9 through pipelines. The inner wall heat dissipation pipeline is composed of a number of shunt heat dissipation pipes 17. The number of shunt heat dissipation pipes 17 are evenly installed on the inner wall of the installation groove 6 and are communicated with the guiding groove 5.

[0024] Further improved, as Figure 2As shown: the lateral regulator includes a push plate 18, a column 19 and a return spring 20. The end of the push plate 18 is located on the inner side of the socket 14 and the bottom is connected to the column 19. The column 19 is connected to the return spring 20. The end of the return spring 20 is fixed in the inner cavity 11. The movement of the push plate 18 can drive the movable plate 15 to move horizontally and perform the lifting and lowering adjustment of the floating heat sink.

[0025] Further improvement, such as Figure 2 As shown: a plurality of groups of convex balls 21 are fixed on the upper and lower surfaces of the push plate 18. The convex balls 21 are used in conjunction with the floating heat sink. The convex balls 21 act on the floating heat sink, so that the floating heat sink can move.

[0026] Further improvement, such as Figure 2 and 3 As shown: the movable plate 15 includes a plate body 22 and a floating ball 23 fixed to the outer side of the plate body 22. The floating ball 23 is a spherical structure and a horizontal plate 24 is arranged on the top. Two groups of vertical plates 25 are symmetrically installed on the upper end of the horizontal plate 24. A plurality of groups of blocking pieces 26 are evenly installed on the vertical plates 25. The blocking pieces 26 are used in conjunction with the shunt heat dissipation pipe 17. When the plate body 22 moves inward, the floating ball 23 contacts the horizontal plate 24, so that the horizontal plate 24 moves up, so that the blocking piece 26 is staggered from the inner end of the shunt heat dissipation pipe 17. At this time, the airflow can enter the shunt heat dissipation pipe 17 through the guide groove 5.

[0027] Further improvement, such as Figure 1 As shown, the shunt heat dissipation pipe 17 includes a pipe body 27 and a plurality of exhaust holes 28 evenly opened on the surface of the pipe body 27. The pipe body 27 is fixed on the inner wall of the mounting groove 6. The gas is vertically directed onto the components through the shunt heat dissipation pipe 17.

[0028] Further improvement, such as Figure 4 and 5 As shown: the floating heat sink includes an air intake hood 29, a diverter plate 30, a top plate 31, an air inlet 32 ​​and an exhaust port 33. The top of the air intake hood 29 is connected to the top plate 31 through the diverter plate 30. The lower end of the diverter plate 30 is in a stacked structure. The air inlet 32 ​​is opened on one side of the top plate 31 and is connected to the compressor 9 through a pipeline. An annular cooling pipe 34 is provided at the inner end of the air inlet 32. The exhaust port 33 is opened at the upper right corner of the top plate 31. The airflow below enters the diverter plate 30 along the air intake hood 29 and is cooled by the cooling medium of the annular cooling pipe 34. The airflow is then guided to the components for heat dissipation through the diverter head 36.

[0029] Further improvement, such as Figure 5As shown in the figure: A diversion cavity 35 is provided inside the flow splitter plate 30, and a number of groups of flow splitters 36 are symmetrically installed on both sides. The outer diameter of the flow splitter 36 is larger than the inner diameter. The air flow is guided by the flow splitter 36 to dissipate heat from the components.

[0030] Specifically, the annular cooling pipe 34 has an annular structure and is connected to the exhaust port 33 through a pipe at the upper right corner. The cooling air flow generated by the compression of the compressor 9 can be guided into the annular cooling pipe 34 through the annular cooling pipe 34. The gas entering through the air inlet hood 29 is cooled by the annular cooling pipe 34. Such a design method can ensure that the compressor 9 achieves the purpose of cooling the air flow under the condition of low-power operation, achieving the purpose of energy saving.

[0031] During use: When heat dissipation treatment is required for the components inside the cabinet 1 of the present invention, the air flow can be introduced into the inner cavity 11 through the induced draft fan 13. Part of the air flow enters the flow split heat dissipation pipe 17 along the guiding groove 5 and laterally dissipates heat from the components through the flow split heat dissipation pipe 17. Another part of the air flow enters the floating heat dissipation fins. The cooling air flow generated by the compression of the compressor 9 can be guided into the annular cooling pipe 34 through the annular cooling pipe 34. The gas entering through the air inlet hood 29 is cooled by the annular cooling pipe 34. Such a design method can ensure that the compressor 9 achieves the purpose of cooling the air flow under the condition of low-power operation, achieving the purpose of energy saving, and can achieve longitudinal heat dissipation treatment. In addition, when the cabinet door 1 needs to be opened for maintenance of the internal components, when the cabinet door is in the open state, the push rod 10 is separated from the socket 14. At this time, under the action of the return spring 20, the lower push plate 18 is reset, the moving plate 15 moves outward and the cross plate 24 drops, the blocking piece 26 re-blocks the flow split heat dissipation pipe 17, and the floating heat dissipation fins are reset, and the flow splitters 36 are hidden, reducing the possibility of external dust entering the cabinet.
