Description

Technical Field

[0001] The utility model relates to the technical field of switch cabinets, in particular to a switch cabinet. Background Art

[0002] With the rapid development of the industrial and transportation fields, the outdoor temperature has also increased compared with previous years, which has led to higher and higher requirements for the heat dissipation effect of high and low voltage switch cabinets. This is because the components in the switch cabinet will generate a lot of heat when working, and this heat must be dissipated in time, otherwise the accumulated heat will cause the temperature in the switch cabinet to rise to a very high temperature, seriously affecting the normal operation of the components and greatly shortening their working life;

[0003] At present, the heat dissipation method adopted by traditional switch cabinets is to set multiple heat dissipation holes on the side wall and use natural convection between cold air and hot air to dissipate heat. The convection wind in the vertical direction has a very small range, so the heat dissipation effect is limited. Therefore, there is an urgent need to provide a switch cabinet. Utility Model Content

[0004] The purpose of this section is to summarize some aspects of the embodiments of the utility model and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the abstract of the specification and the name of the utility model of this application to avoid blurring the purpose of this section, the abstract of the specification and the name of the utility model, and such simplifications or omissions cannot be used to limit the scope of the utility model.

[0005] Therefore, the purpose of the utility model is to provide a switch cabinet, which drives the position of the partition to change by driving a motor, and cooperates with the wind shield to seal the partition, so as to flexibly adjust the heat dissipation effect of the ventilation structure, so that it is suitable for ventilation of the switch cabinet under different temperatures, and ensure that the switch cabinet can work normally and stably under different temperatures. When the airflow enters the bottom of the switch cabinet body, the bottom can store a large amount of airflow, so that the air pressure at the bottom is greater than the internal air pressure, which can increase the speed of the airflow. At the same time, when the airflow flows in through the air inlet hole and flows out of the air outlet hole, the upper hole is small and the lower hole is large, the airflow speed entering the top of the partition can be increased, which can not only enhance the heat dissipation effect but also discharge the dust adsorbed on the components inside the cabinet out of the cabinet.

[0006] In order to solve the above technical problems, according to one aspect of the present invention, the present invention provides the following technical solutions:

[0007] A switch cabinet, comprising:

[0013] As a preferred solution of a switch cabinet described in the utility model, the ventilation component includes a partition connected to the top of the base plate, and a ventilation fan installed on the top of the switch cabinet body, the bottom of the partition is rectangular and has multiple groups of air inlet holes equidistantly arranged, and the top of the partition has multiple groups of air outlet holes connected to the air inlet holes.

[0014] As a preferred solution of a switch cabinet described in the utility model, in order to facilitate smoother air flow, the inner diameter of the air inlet hole is 50-80mm, the inner diameter of the air outlet hole is 20-30mm, and the air inlet hole has an inner curved surface shaped like a mineral water bottle mouth.

[0015] As a preferred solution of the switch cabinet described in the utility model, wherein: the partition is provided with a plurality of groups of through holes linearly and equidistantly from left to right, and the inner diameter of the through holes is 30-50 mm.

[0016] As a preferred solution of a switch cabinet described in the utility model, wherein: a slide plate slidably matched with a slide groove is connected to the outer side of the switch cabinet body, and a connecting hole is opened on the slide plate to connect a dustproof mesh plate.

[0017] As a preferred solution of a switch cabinet described in the utility model, wherein: a wind shield is connected to the switch cabinet body, the wind shield is arranged corresponding to the front side of the partition, and a guide groove for guiding the partition is opened on the wind shield.

[0018] Compared with the prior art, the utility model has the following beneficial effects:

[0019] 1.

[0020] 2. When the airflow enters the bottom of the switch cabinet, the bottom can store a large amount of airflow, causing the air pressure at the bottom to be greater than the internal air pressure, which can increase the speed of the airflow. At the same time, the airflow flows in through the air inlet hole and flows out through the air outlet hole.

[0031] The utility model provides a switch cabinet, please refer to Figure 1-4 , including a switch cabinet 100, an adjustment component 200 and a ventilation component 300;

[0032] Please continue reading Figure 1-4 , as a switch cabinet 100 connected to the base frame, the switch cabinet 100 has slide grooves 110 on both sides of the bottom, and the slide grooves 110 have multiple groups of vents 111 connected to the switch cabinet 100, and the vents 111 serve as air inlets of the ventilation component 300;

[0033] The outside of the switch cabinet 100 is connected to a slide plate 120 that slidably cooperates with the slide groove 110. The slide plate 120 is provided with a connection hole connected to a dustproof screen plate 121. The switch cabinet 100 is connected to a windshield plate 130. The windshield plate 130 is arranged corresponding to the front side of the partition plate 310, and the windshield plate 130 is provided with a guide groove 131 for guiding the partition plate 310. The dustproof screen plate 121 can be provided to assist in filtering dust in the air during the air supply process to prevent dust from entering the cabinet through the vent 111. The slide plate 120 is slidably connected to the slide groove 110, which is convenient for disassembly and assembly of the dustproof screen plate 121, and is convenient for subsequent cleaning and replacement.

[0034] Please continue reading Figure 2-4 , the regulating component 200 is placed in the switch cabinet 100, and the position of the ventilation component 300 is adjusted so that the temperature in the cabinet can be maintained in a relatively moderate and stable state;

[0035] The adjusting component 200 includes a driving motor 210 threadedly connected to the rear side of the switch cabinet 100, and a connecting frame 220 connected to the switch cabinet 100. The output end of the driving motor 210 extends into the connecting frame 220. The output end of the driving motor 210 is connected to a threaded screw 211. A threaded seat 230 is threadedly connected to the threaded screw 211. The driving motor 210 drives the threaded screw 211 to rotate, thereby driving the threaded seat 230 connected to the threaded screw 211 to rotate.

[0036] A connecting groove 221 is provided in the connecting frame 220, and a limiting groove 222 connected to the connecting groove 221 is provided on the top of the connecting frame 220. A limiting seat 231 is integrally formed on the outer side of the threaded seat 230 and matched with the limiting guide of the limiting groove 222. The top of the limiting seat 231 is connected to the base plate 232.

[0037] Since the rotation direction of the threaded seat 230 is restricted, when the threaded screw 211 rotates, the threaded seat 230 translates along the direction of the threaded screw 211 (thread feeding action), driving the position of the partition 310 to change. The partition 310 is blocked by the wind shield 130, and the heat dissipation effect of the ventilation structure can be flexibly adjusted, so that it is suitable for ventilation of the switch cabinet under different temperatures, ensuring that the switch cabinet 100 can work normally and stably under different temperatures;

[0038] Please continue reading Figure 1 , Figure 3 and Figure 4 , the ventilation component 300 is connected to the regulating component 200 to assist ventilation inside the switch cabinet 100;

[0039] The ventilation component 300 includes a partition 310 connected to the top of the base plate 232, and a ventilation fan 330 threadedly connected to the top of the switch cabinet 100. The bottom of the partition 310 is rectangular and has multiple groups of air inlet holes 311 equidistantly provided thereon. The top of the partition 310 has multiple groups of air outlet holes 312 connected to the air inlet holes 311. The ventilation fan 330 works in conjunction with the air inlet holes 311 and the air outlet holes 312 to ventilate and dissipate heat inside the switch cabinet 100. When the airflow enters the bottom of the switch cabinet, the bottom can store a large amount of airflow, causing the air pressure at the bottom to be greater than the air pressure inside, thereby increasing the speed of the airflow. At the same time, when the airflow flows in through the air inlet holes 311 and flows out through the air outlet holes 312, the airflow speed entering the top of the partition 310 can be increased due to the small upper hole and the large lower hole, thereby enhancing the heat dissipation effect and discharging the dust adsorbed on the components inside the cabinet out of the cabinet.

[0040] Furthermore, in order to facilitate smoother air flow, the inner diameter of the air inlet 311 is 50-80 mm, the inner diameter of the air outlet 312 is 20-30 mm, and the air inlet 311 has an inner curved surface in the shape of a mineral water bottle mouth;

[0041] Working principle: When the utility model is in use, the position of the partition 310 is changed by driving the motor 210, and the partition 310 is blocked by the wind shield 130, so that the heat dissipation effect of the ventilation structure can be flexibly adjusted, so that it is suitable for ventilation of the switch cabinet under different temperatures, ensuring that the switch cabinet 100 can work normally and stably under different temperatures. Moreover, when the airflow enters the bottom of the switch cabinet body, a large amount of airflow can be stored at the bottom, causing the air pressure at the bottom to be greater than the internal air pressure, which can increase the speed of the airflow. At the same time, when the airflow flows in through the air inlet 311 and flows out through the air outlet 312, since the upper hole is small and the lower hole is large, the airflow speed entering the top of the partition 310 can be increased, which can not only enhance the heat dissipation effect but also discharge the dust adsorbed on the components inside the cabinet body out of the cabinet.

[0042] Although the present invention has been described above with reference to the embodiments, various modifications may be made thereto and parts thereof may be replaced with equivalents without departing from the scope of the present invention. In particular, as long as there is no structural conflict, the various features in the embodiments disclosed in the present invention may be used in combination with each other in any manner, and the fact that these combinations are not exhaustively described in this specification is only for the sake of omitting space and saving resources. Therefore, the present invention is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.
