Description

Technical Field

[0001] The invention belongs to the technical field of cabinet equipment, and in particular relates to an electric power dispatching automation cabinet which is conducive to heat dissipation. Background Art

[0002] The existing electric power dispatching automation cabinet generally dissipates heat by opening heat dissipation holes on the cabinet body. The heat dissipation efficiency is low and the heat dissipation effect is poor. The heat inside the cabinet cannot be effectively removed, which can easily lead to damage to some electrical components in the cabinet due to the inability to dissipate heat. In addition, the existing electric dispatching automation cabinet cannot prevent the entry of external dust while dissipating heat, and dust can easily accumulate inside the cabinet for a long time, which not only affects the use of electrical components in the cabinet, but also easily blocks the heat dissipation holes and reduces the heat dissipation efficiency.

[0003] Chinese invention patent CN215872461U discloses an electric power dispatching automation cabinet that is conducive to heat dissipation. The electric power dispatching automation cabinet that is conducive to heat dissipation, through the coordinated arrangement of the cabinet, vertical plate, horizontal plate, transmission mechanism, slide groove, first heat dissipation port, movable frame, cover plate, second heat dissipation port, first filter screen, cleaning plate and second filter screen, can simply dissipate heat inside the cabinet through the fan and the first heat dissipation hole, and the cover plate can be driven to move upward on the threaded rod by a conveyor belt, and then the first heat dissipation port on the top of the cabinet is fully opened, thereby increasing the heat dissipation area, effectively improving the heat dissipation efficiency, and thus enhancing the heat dissipation effect. At the same time, the first filter screen and the second filter screen can prevent external dust from directly entering the cabinet during the heat dissipation process.

[0004] In the prior art, fans are usually used to dissipate heat directly. However, direct blowing of fans may cause heat to spread over a larger range. When fans blow directly at a heat source, local overheating may occur due to irregular surface shape of the heat source or uneven heat dissipation. Summary of the invention

[0005] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and the specification abstract and the invention title of this application to avoid blurring the purpose of this section, the specification abstract and the invention title, and such simplifications or omissions cannot be used to limit the scope of the present invention.

[0006] In order to solve the problems raised in the above background technology, the present invention adopts the following technical solutions.

[0007] A power dispatching automation cabinet that is conducive to heat dissipation includes an outer cabinet and an inner cabinet, wherein the inner cabinet is placed inside the outer cabinet and a support leg is provided at the bottom of the inner cabinet, a cavity is formed between the inner cabinet and the bottom of the outer cabinet through the support leg, a refrigerator is provided in the cavity, a plurality of through holes are equidistantly provided on one side of the inner cabinet, connecting air ducts are welded outside the through holes, ends of the connecting air ducts are commonly connected to an air duct, a plurality of fans are evenly provided at the bottom of the air duct, a hood is sleeved on the top of the air duct, a plurality of ventilation holes are equidistantly provided on the side of the hood, and air inlet holes are evenly provided on the other side of the inner cabinet.

[0008] Preferably, the air inlet is covered with a filter frame, and a plurality of cooling tubes are inserted into the filter frame at equal distances along the height direction. The upper end of the cooling tube is connected to an input tube, and the lower end of the cooling tube is connected to an output tube. One end of the input tube is connected to the output end of the refrigerator, and one end of the output tube is connected to the input end of the refrigerator. The cooling tube and the refrigerator are filled with refrigerant.

[0009] Preferably, a filter screen is provided on the outer surface of the filter frame, and slide rails are provided on both sides of the filter frame, and a cleaning brush is slidably connected to the slide rails. The cleaning brush moves along the height direction of the filter frame to remove dust on the filter screen.

[0010] Preferably, a motor is fixedly mounted on the side of the cleaning brush, a gear is fixedly sleeved on the driving end of the motor, a rack is also provided on the side of the filter frame mounted on the inner cabinet, and the gear is meshed with the rack.

[0011] Preferably, the upper end of the air duct passes through the top of the outer cabinet, and a slide groove is provided on a side section of the air duct protruding from the outer cabinet. The length of the slide groove is less than the height of the hood. The hood is slidably connected to the top of the air duct through the slide groove. The hood is made of plastic injection molding. When the fan is started, the hood is lifted up by wind force, and air is discharged outward through the ventilation holes opened on the side of the hood.

[0012] Preferably, an iron sheet is provided in the center of the inner top of the hood, and an electromagnetic lock is connected to the air duct through a bracket, the upper surface of the electromagnetic lock contacts the bottom surface of the iron sheet, and the electromagnetic lock is powered by the power dispatching automation cabinet.

[0013] Preferably, a plurality of card slots are symmetrically provided on the inner side of the inner cabinet, and the inner cabinet is connected to a support plate through the card slots. The support plate is a hollow structure, and the support plate is arranged between the upper and lower through holes. The front surface of the inner cabinet is rotatably connected to the inner cabinet door.

[0014] Preferably, a shutter is provided on the side of the outer cabinet, the shutter is on the same side as the ventilation hole opened on the side of the inner cabinet, and an outer cabinet door is hinged on the front surface of the outer cabinet.

[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention extracts the heat generated by the electrical components in the inner cabinet through the air duct, the fan and the connecting air duct. The operation of the fan causes the air in the air duct to flow. At the portion where the connecting air duct is connected to the inner cabinet, the air is driven by the fan to generate a flow trend, thereby forming a relative negative pressure at the connecting air duct, causing the hot air around the inner cabinet to be sucked into the air duct. This design can more accurately extract the heat generated by the electrical components into the air duct. Compared with direct blowing by the fan, direct blowing by the fan will cause the heat to spread in a larger range and may affect other equipment or areas that do not need heating. By means of negative pressure extraction, the heat can be concentrated and guided into the air duct, which is convenient for subsequent heat treatment, and the hot air can be promptly extracted from the space around the heat source to reduce the impact of the hot air on the surrounding environment.

[0016] Furthermore, when the fan blows directly into the inner cabinet, local overheating may occur due to the irregular surface shape of the heat source of the electrical component or uneven heat dissipation. The negative pressure heat extraction method can extract the heat around the heat source relatively evenly, reducing the impact of local overheating on the heat source itself or surrounding equipment.

[0017] The present invention arranges a filter frame outside the air inlet of the inner cabinet, which can effectively filter impurities in the air entering the inner cabinet, thereby reducing the degree of dust adhesion on the electrical components. At the same time, a cleaning brush is arranged on the filter frame, and the cleaning brush can regularly clean the dust and impurities on the filter screen to prevent these substances from clogging the filter screen, thereby maintaining the air permeability and filtering efficiency of the filter screen. Moreover, since the cleaning brush can automatically or semi-automatically perform the cleaning work, the frequency and workload of manual cleaning are reduced, thereby saving maintenance costs. Keeping the filter screen clean can ensure the normal operation of the equipment and reduce equipment failures and downtime caused by filter screen clogging.

[0018] The present invention is provided with a cooling pipe in the filter frame, which can cool the air entering the inner cabinet, thereby improving the heat dissipation efficiency. The cooling pipe is arranged on the side of the inner cabinet opposite to the air duct to prevent the cross-wind of cold air and hot air, thereby improving the heat dissipation effect. The external cooling pipe reduces the space occupied in the left and right directions, so that the space of the inner cabinet is larger, which is conducive to the installation of electrical components and air flow.

The present invention provides the following embodiments.

[0029] See also Figure 1 and Figure 2 , an electric power dispatching automation cabinet that is conducive to heat dissipation, the automation cabinet in this embodiment includes an outer cabinet 100 and an inner cabinet 200, the outer cabinet 100 mainly plays the role of protecting the inner cabinet 200 and other accessories, and can resist external corrosion and weathering of the inner cabinet 200, and the inner cabinet 200 is placed in the outer cabinet 100, Further, in this embodiment, a plurality of through holes are evenly spaced on one side of the inner cabinet 200, and a connecting air duct 2043 is welded outside the through hole. The ends of the connecting air duct 2043 are commonly connected to the air duct 204, and a plurality of fans 2042 are evenly arranged at the bottom of the air duct 204. The other side of the inner cabinet 200 is evenly provided with air inlet holes. In this embodiment, the heat generated by the electrical components in the inner cabinet 200 is extracted through the air duct 204, the fan 2042 and the connecting air duct 2043. The specific principle is: the operation of the fan 2042 causes the air in the air duct 204 to flow, and the air is drawn by the fan 2042 at the portion where the connecting air duct 2043 is connected to the inner cabinet 200. 42 drives a flow trend, thereby forming a relative negative pressure at the connection air duct 2043, causing the hot air around the inner cabinet 200 to be sucked into the air duct 204. The design in this embodiment can more accurately extract the heat generated by the electrical components into the air duct 204. Compared with direct blowing by the cooling fan, direct blowing by the cooling fan will cause the heat to spread in a larger range, which may affect other equipment or areas that do not need heating. By using negative pressure extraction, the heat can be concentrated and guided into the air duct 204, which is convenient for subsequent heat treatment, and the hot air can be promptly extracted from the space around the heat source to reduce the impact of the hot air on the surrounding environment.

[0030] See also Figure 2 and Figure 3 In order to further improve the heat dissipation efficiency, in this embodiment, a filter frame 202 is covered outside the air inlet hole, and a plurality of cooling pipes 2021 are inserted into the filter frame 202 at equal intervals along the height direction. The cooling pipe 2021 has a built-in refrigerant, and the upper end of the cooling pipe 2021 is connected to an input pipe 2022, and the lower end of the cooling pipe 2021 is connected to an output pipe 2023. In this embodiment, the cooling pipe 2021 is arranged in the filter frame 202, which can cool the air entering the inner cabinet 200, thereby improving the heat dissipation efficiency. The cooling pipe 2021 is arranged on the side of the inner cabinet 200 opposite to the air duct 204 to prevent cold air and hot air from being blown, thereby improving the heat dissipation effect, and the external cooling pipe 2021 reduces the space occupied in the left and right directions, so that The space of the inner cabinet 200 is larger, which is conducive to the installation of electrical components and air flow. At the same time, in order to realize the circulation of the refrigerant, the present embodiment is provided with a support foot at the bottom of the inner cabinet 200, and the inner cabinet 200 forms a cavity with the bottom of the outer cabinet 100 through the support foot. A refrigerator is arranged in the cavity, one end of the input pipe 2022 is connected to the output end of the refrigerator, and one end of the output pipe 2023 is connected to the input end of the refrigerator. The refrigerator is also filled with refrigerant. The present embodiment realizes the circulation of the refrigerant in the cooling pipe 2021 through the refrigerator. The name of the refrigerator in this application may be different from the name of the existing equipment, but its principle is the same as the refrigeration process of the refrigerator in the prior art, so it is not disclosed in detail in this application.

[0031] See also Figure 3In this embodiment, a filter screen is provided on the outer surface of the filter frame 202, so that the air entering the inner cabinet 200 is filtered through the filter frame 202. Furthermore, in order to ensure the amount of air entering, slide rails 2032 are provided on both sides of the filter frame 202 in this embodiment. A cleaning brush 203 is slidably connected to the slide rail 2032. The cleaning brush 203 moves along its height direction on the filter frame 202 to remove dust on the filter screen. In this embodiment, the cleaning brush 203 can regularly clean the dust and impurities on the filter screen to prevent these substances from clogging the filter screen, thereby maintaining the air permeability and filtering efficiency of the filter screen, and a motor is fixedly installed on the side of the cleaning brush 203. 2031, a gear is fixedly sleeved on the driving end of the motor 2031, and a rack 2033 is also provided on the side of the filter frame 202 installed on the inner cabinet 200, and the gear is meshed with the rack 2033. The above design drives the gear to rotate on the rack 2033 through the motor 2031, so that the cleaning brush 203 moves on the filter screen and then completes the cleaning of the filter screen. Due to the above design, the cleaning brush 203 can automatically perform the cleaning work, reducing the frequency and workload of manual cleaning, thereby saving maintenance costs. Keeping the filter screen clean can ensure the normal operation of the equipment and reduce equipment failures and downtime caused by filter screen blockage.

[0032] See also Figure 6 In this embodiment, a hood 2041 is sleeved on the top of the air duct 204, and a plurality of ventilation holes are evenly spaced on the side of the hood 2041. The hood 2041 covers the air outlet on the top of the air duct 204, which can effectively prevent dust, rain and other impurities from entering the pipe through the air outlet of the air duct 204, thereby polluting the inner cabinet 200. In order to ensure the outflow of hot air, in this embodiment, the upper end of the air duct 204 passes through the top of the outer cabinet 100, so that the hot air is directly discharged to the outside of the outer cabinet 100. At the same time, in order to ensure that the hood 2041 does not enter the air outlet of the air duct 204, the upper end of the air duct 204 passes through the top of the outer cabinet 100, thereby polluting the inner cabinet 200. The hood 2041 is slidably connected to the top of the air duct 204 through the slide groove. The material used for controlling the hood 2041 is usually made of plastic injection molding, which makes the hood 2041 lighter and easier to replace later. When the fan 2042 is started, the lightweight hood 2041 is lifted up by wind force, and air is discharged outward through the ventilation holes on the side of the hood 2041.

[0033] Continue reading Figure 6In this embodiment, an iron sheet 2044 is provided in the center of the inner top of the wind cap 2041, and an electromagnetic lock 2045 is connected to the air duct 204 through a bracket. The upper surface of the electromagnetic lock 2045 contacts the bottom surface of the iron sheet 2044. The electromagnetic lock 2045 is powered by the power dispatching automation cabinet. In this embodiment, by powering the electromagnetic lock 2045, the electromagnetic lock 2045 can absorb the iron sheet 2044, so that the wind cap 2041 is tightly sleeved on the air duct 204, thereby sealing the air duct 204. The function is: when the cleaning brush 203 moves along the height direction of the filter frame 202 to remove the dust on the filter screen, some of the dust washed off will enter the inner cabinet through the ventilation holes opened on the side of the inner cabinet 200. Therefore, when cleaning the filter screen, the air outlet on the top of the air duct 204 is sealed by the wind cap 2041, and the wind from the fan 2042 will enter the inner cabinet 200 through the connecting air duct 2043 and blow out from the ventilation holes on the side of the inner cabinet 200, so that dust cannot enter the inner cabinet 200, thereby ensuring the cleanliness of the inside of the inner cabinet 200.

[0034] See also Figure 3 In this embodiment, a plurality of card slots are symmetrically provided on the inner side of the inner cabinet 200. The inner cabinet 200 is connected to a support plate 201 through the card slots. The support plate 201 is a hollow structure. The electrical components are mounted on the support plate 201. The support plate 201 is arranged between the upper and lower through holes to facilitate the flow of hot air. The front surface of the inner cabinet 200 is rotatably connected to an inner cabinet door to protect the electrical components inside the inner cabinet 200.

[0035] See also Figure 1 A shutter is provided on the side of the outer cabinet 100, through which outside air can enter the outer cabinet 100, and then enter the inner cabinet 200 through the filter frame 202. The shutter is on the same side as the ventilation holes opened on the side of the inner cabinet 200, and an outer cabinet door is hinged on the front surface of the outer cabinet 100 to protect the inner cabinet 200.
