Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, in particular to an electrical cabinet with high efficiency heat dissipation. Background Art

[0002] The electrical cabinet is made of steel and is used to protect the normal operation of components. The materials used to make electrical cabinets are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the manufacture of electrical cabinets. Electrical cabinets are widely used and are mainly used in the chemical industry, environmental protection industry, power system, metallurgical system, transportation industry, etc.

[0003] There are many existing technologies for electrical cabinets, such as:

[0004] Chinese Patent Application No.: 202022319336.8 discloses that a heat dissipation fan, a first circulation airflow hole, a second circulation airflow hole, a flow cavity, a first dust filter, a second dust filter and a heat dissipation hole are provided. When in use, the wind blown by the heat dissipation fan enters the flow cavity through the first circulation airflow hole and the second circulation airflow hole, and then flows out through the heat dissipation hole after being filtered by the first dust filter and the second dust filter, so as to dissipate heat for the electrical cabinet, improve the heat dissipation efficiency of the electrical cabinet, and improve the dustproof effect of the electrical cabinet. By providing a slide groove, a slider, a screw, a line installation plate, a winding rod, a wire clamping groove, a clamping groove, a clamping block, a fixed base plate and a servo motor, during maintenance, the servo motor drives the screw to rotate, drives the slider to slide along the inner side of the screw on the slide groove, thereby driving the line installation plate to slide out from the inner side of the main cabinet to repair the damaged lines installed on the winding rod and the wire groove, so as to facilitate the maintenance of the installed circuit, and is conducive to increasing the maintenance space. It is more time-saving and labor-saving during maintenance, and is convenient for winding and arranging the overlong lines inside the electrical cabinet.

[0005] When the above-mentioned electrical cabinet dissipates heat, it is necessary to use a cooling fan to absorb the air outside the electrical cabinet into the electrical cabinet through the filter, so as to dissipate the heat of the electronic components inside the electrical cabinet. The filter can prevent dust and impurities outside the electrical cabinet from entering the electrical cabinet, thereby protecting the electrical cabinet. At this time, a lot of dust will remain on the surface of the filter and need to be cleaned, so it is often necessary to disassemble and clean the filter, which is quite troublesome. At present, it is inconvenient to disassemble the filter when the electrical cabinet is in use. In this way, a large amount of dust will be attached to the surface of the filter when the electrical cabinet is running for a long time, making it difficult for air to enter the interior of the electrical cabinet, thereby reducing the heat dissipation effect, and the large amount of accumulated dust is not convenient to guide. Utility Model Content

[0006] The purpose of the utility model is to solve the above shortcomings and provide an electrical cabinet with high efficiency heat dissipation;

[0007] To achieve the above-mentioned purpose, the utility model provides an electrical cabinet with high efficiency and heat dissipation, comprising a cabinet body and a protective door hinged at an opening on the surface of the cabinet body, the outer wall of the cabinet body is provided with a groove, the groove connects the outside and the inside of the cabinet body, a dust filter is slidably connected to the inner wall of the groove, and a plurality of long brushes are also provided inside the groove, the rear surface of the dust filter is snugly matched with the end of the long brush, and an inclined plate for guiding accumulated dust is provided on the side of the groove close to the long brush.

[0008] As a further improvement of the technical solution, the top of the dust filter extends out of the inner cavity of the groove and is fixedly connected to a handle, and the top of the long brush extends out of the inner cavity of the groove and is fixedly connected to a slide plate.

[0009] As a further improvement of the technical solution, the dust filter and the long brush are stacked, and the rear surface of the long brush is in contact with the end of the inclined plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the electrical cabinet with high efficiency and heat dissipation, the dust filter slides inside the groove. At this time, the long brush is located in the groove. As the filter slides upward, the long brush cleans the surface of the dust filter to prevent dust from affecting the air flow, and the scraped dust is located on the outer wall of the long brush. The dust accumulates for a long time and can gather on the surface of the inclined plate, so that the dust can slide down along the inclined surface of the inclined plate to prevent the swept dust from accumulating.

[0020] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0021] Electrical cabinets are made of steel and are used to protect the normal operation of components. The materials used to make electrical cabinets are generally divided into hot-rolled steel plates and cold-rolled steel plates. Cold-rolled steel plates are softer than hot-rolled steel plates and are more suitable for the manufacture of electrical cabinets. Electrical cabinets are widely used in the chemical industry, environmental protection industry, power system, metallurgical system, transportation industry, etc. Therefore, please refer to Figure 1-Figure 4 As shown, the present embodiment provides an electrical cabinet with high efficiency and heat dissipation, comprising a cabinet body 1 and a protective door 2 hinged at an opening on the surface of the cabinet body 1. The protective door 2 is arranged so that the interior of the cabinet body 1 is exposed when it is opened, thereby ensuring the integrity of the structure. A groove 11 is arranged on the outer wall of the cabinet body 1, and the groove 11 connects the outside world and the interior of the cabinet body 1. A dust filter 12 is slidably connected to the inner wall of the groove 11, and a plurality of long brushes 15 are also arranged inside the groove 11. The rear surface of the dust filter 12 fits snugly with the end of the long brush 15, and an inclined plate 16 for guiding accumulated dust is arranged on one side of the groove 11 close to the long brush 15. The dust filter 12 slides inside the groove 11, and at this time, the long brush 15 is located in the groove 11. As the filter 12 slides upward, the long brush 15 cleans the surface of the dust filter 12 to prevent dust from affecting the airflow.

[0022] The improvement of this embodiment is that:

[0023] The dust filter 12 slides inside the groove 11, and the long brush 15 is located in the groove 11. As the filter 12 slides upward, the long brush 15 cleans the surface of the dust filter 12 to prevent dust from affecting the air flow, and the scraped dust is located on the outer wall of the long brush 15. Dust accumulated for a long time can gather on the surface of the inclined plate 16, so that the dust can slide down along the inclined surface of the inclined plate 16 to avoid accumulation of the swept dust.

[0024] The utility model takes into account that it is inconvenient to disassemble the filter screen when the electrical cabinet is in use. In this way, long-term operation of the electrical cabinet will cause a large amount of dust to adhere to the surface of the filter screen, making it difficult for air to enter the interior of the electrical cabinet, thereby reducing the heat dissipation effect, and the large amount of accumulated dust is inconvenient to guide. Since the dust filter screen 12 and the long brush 15 are easily damaged after a long time, it is necessary to regularly take out the dust filter screen 12 and the long brush 15 from the cabinet body 1 for cleaning, and it is necessary to extend the inner cavity of the groove 11 at the top of the dust filter screen 12 and fix it with a handle 13, and the top of the long brush 15 extends out of the inner cavity of the groove 11 and is fixedly connected to the slide plate 14. When disassembling the dust filter screen 12, the staff holds the handle 13 by hand to slide the dust filter screen 12 upward along the inside of the groove 11, and the dust filter screen 12 is disassembled, which is convenient for subsequent maintenance and replacement. When disassembling the long brush 15, the staff holds the slider 14 to slide the long brush 15 upward along the inside of the groove 11, and disassembles the long brush 15, which is convenient for subsequent maintenance and replacement.

[0025] When the electrical cabinet is in use, the electrical components inside it will generate vibrations when working. If there is no limit between the dust filter 12 and the long brush 15, it is easy to cause shaking and damage. Therefore, the dust filter 12 and the long brush 15 are stacked, and the rear surface of the long brush 15 fits the end of the inclined plate 16. The rear surface of the long brush 15 fits the end of the inclined plate 16, which provides a stable support. The structure between the dust filter 12 and the long brush 15 is more solid, which helps to keep their position stable in a vibrating environment and reduces the risk of damage.

[0026] When the long brush 15 is fixed on the surface of the dust filter 12, a lot of dust will remain on the surface of the long brush 15 due to the heat dissipation of the internal electronic components and the production environment of the workshop. Therefore, several long brushes 15 need to be connected and fixed in parallel with each other, and a long cavity is formed between two adjacent long brushes 15. The cavity design can prevent excessive dust accumulation between the brushes, maintain smooth air circulation, and extend the service life of the filter and the brush. The long cavity design makes it easy to remove dust and impurities, simplifies maintenance and cleaning work, and reduces maintenance costs and workload.

[0027] In order to dissipate heat inside the electrical cabinet, a cooling fan needs to work. Since the distribution positions of electronic components are not consistent, some electronic components installed far away from the cooling fan cannot be cooled quickly. Therefore, a support plate 21 is required to be fixedly connected to the bottom of the inner wall of the cabinet 1. A plurality of grooves are provided on the surface of the support plate 21. A cooling fan for generating airflow upward from the grooves is provided inside the support plate 21. The distribution of the grooves can guide the airflow to be more evenly distributed inside the electrical cabinet, avoiding the formation of local hot spots and ensuring that all components can be adequately cooled.

[0028] When the electrical cabinet with high efficiency heat dissipation of the utility model is used in specific use, the heat dissipation device inside the cabinet 1 can make the air outside the cabinet 1 enter the interior of the cabinet 1 through the dust filter 12. At this time, the dust filter 12 will filter the air entering the interior of the cabinet 1 from the outside to prevent dust and impurities from entering the interior of the cabinet 1. Because the electrical cabinet is generally installed in a production workshop, there is a lot of dust. The surface of the dust filter 12 will be attached with a lot of dust due to long-term work. These dust will affect the operation of the cooling fan. The long brush 15 can be used to clean the dust on the surface of the dust filter 12 by sliding the slide plate 14, and the movement of the long brush 15 can make the mesh diameter of the surface of the dust filter 12 larger. In this way, when the heat dissipation device is working, the mesh will not be blocked by dust, so that the air cannot enter the interior of the cabinet 1, resulting in a decrease in the heat dissipation effect. The dust filter 12 can be moved out of the cabinet 1 by pulling the handle 13. At this time, the cabinet 1 can be cleaned, and the presence of the long brush 15 can reduce the frequency of cleaning.

[0029] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected.
