Description

Technical Field

[0001] This utility model belongs to the technical field of shielded dustproof heat dissipation window, specifically relating to a shielded dustproof heat dissipation window and power supply cabinet. Background Technology

[0002] Power supplies are used to continuously supply power to external devices. During use, the internal battery pack will continuously generate a lot of heat. Therefore, technicians usually install cooling fans on the power supply cabinet to dissipate heat. For power supplies used in harsh environments, such as deserts and sandy areas, they need to meet not only electromagnetic compatibility requirements, but also heat dissipation and protection requirements.

[0003] In the relevant existing technologies, the existing heat dissipation structures have the following defects: First, most of the heat dissipation vents of the enclosure only have a single piece of dustproof cotton, which is not only troublesome to replace, but some products also cannot meet the electromagnetic compatibility requirements, and the waterproof and dustproof effects are not ideal. Second, the existing heat dissipation structures are not reasonably installed and disassembled, and are difficult to assemble. Utility Model Content

[0004] The purpose of this invention is to solve the problems existing in the prior art and provide a shielded dustproof heat dissipation window and power cabinet. This device optimizes the structure and uses the shielded dustproof heat dissipation window as the heat dissipation vent of the cabinet, which not only meets the requirements of waterproof and dustproof, but also meets the requirements of electromagnetic compatibility.

[0005] One of the objectives of this utility model is to provide a shielded dustproof and heat dissipation window, including a dustproof and heat dissipation window, a shielded waveguide window, and a waterproof heat dissipation plate, wherein the dustproof and heat dissipation window, the shielded waveguide window, and the waterproof heat dissipation plate are sequentially attached. The dustproof and heat dissipation window includes a combined frame and a dustproof plate. The combined frame includes a window surrounded by four frames. At least one of the frames has an opening groove formed along its length. The other frames without opening grooves have slots on their inner end faces. The dustproof plate is inserted into the slots within the rectangular window by the opening grooves and is fixed by a baffle.

[0006] As a preferred embodiment, the ends of two opposite frame edges abut against the ends of two other opposite frame edges but are not directly fixedly connected.

[0007] As a preferred embodiment, the frame, the shielded waveguide window, and the waterproof heat dissipation plate are respectively provided with fixing through holes I; the connectors pass through the fixing through holes I of the three in sequence to achieve a fixed connection.

[0008] As a preferred embodiment, the dustproof plate includes an outer frame, and at least two oppositely arranged fixed meshes are provided inside the outer frame, with a gap formed between the two adjacent fixed meshes for installing the dustproof meshes.

[0009] As a preferred embodiment, the frame adopts a channel steel structure, and the channels of the channel steel structure are all set outward from the frame. The fixing through hole I is opened on the wing plate of the channel steel.

[0010] As a preferred embodiment, the baffle is disposed within the groove of the frame, and the baffle is connected to the frame by fasteners.

[0011] As a preferred embodiment, the frame with the slot includes a wide channel steel and a narrow channel steel, the slots of the wide channel steel and the narrow channel steel are opposite to each other, and the base plates of the two are attached and fixedly connected.

[0012] A second objective of this invention is to provide a power cabinet, comprising a cabinet body and any of the aforementioned shielding, dustproof, and heat dissipation windows.

[0013] As a preferred embodiment, the shielding, dustproof, and heat dissipation window is located on the inside of the cabinet door.

[0014] Compared with the prior art, the present invention has at least the following beneficial effects:

[0015] Firstly, this utility model, through optimization and improvement, includes a dustproof heat dissipation window, a shielded waveguide window, and a waterproof heat dissipation plate. The dustproof heat dissipation window is modularly spliced, making it easy to assemble and install without welding. It can be fitted and assembled with the shielded waveguide window and fixed to the inner end face of the waterproof heat dissipation plate. To facilitate the cleaning, maintenance, and replacement of the dustproof plate, at least one frame of the dustproof heat dissipation window is provided with an opening groove, allowing the dustproof plate to be accessed or removed for cleaning or replacement. Additionally, slots are provided on the inner sides of the other frames without opening grooves for positioning and fixing the dustproof plate. Simultaneously, the slots overlap with the edge of the dustproof plate, providing a certain degree of sealing and thus better achieving the dustproof effect.

[0016] Secondly, this utility model fully considers the ease of installation of the shielded dustproof heat dissipation window. Fixing through holes I are provided at the corresponding positions of the dustproof heat dissipation window frame, the shielded waveguide window, and the waterproof heat dissipation plate. The three are connected together and fixed by connectors. In particular, since the four frames of the dustproof heat dissipation window are all connected and fixed through fixing through holes I, the four frames are only connected at the ends and not directly fixed. During installation, the individual frames can be connected and fixed in sequence, which reduces labor intensity and installation difficulty. No welding is required, and a single person can achieve modular and rapid assembly and fixing.

[0017] Thirdly, this utility model, considering the combination of strength and dustproof effect of the dustproof panel, installs a dustproof net between two fixed nets. The dustproof net is made of polyurethane foam, which can pass through and remove dust from the airflow, while the fixed nets are used to strengthen the dustproof net and prevent damage during installation and use. When maintaining the dustproof panel, only the internal dustproof net needs to be cleaned or replaced for reuse. This ensures the strength of the device while also reducing operating costs.

[0018] Fourthly, in this utility model, the card slot and the frame are integrated or fixedly connected as a whole, which further improves the convenience of installation. Since the card slot is pre-fixed on the frame, the card slot is formed after the frame is aligned and fixed in place. Attached Figure Description

[0032] The present invention will now be described in detail through exemplary embodiments. However, it should be understood that, without further description, elements, structures, and features in one embodiment may be advantageously incorporated into other embodiments.

[0033] It should be noted that, unless otherwise defined, the technical or scientific terms used herein should have the ordinary meaning understood by one of ordinary skill in the art to which this utility model pertains. The terms "a," "an," or "the," and similar words used in this utility model patent application specification and claims do not express a quantity limitation, but rather indicate the presence of at least one. Terms such as "comprising" or "including" indicate that the elements or objects preceding "comprising" encompass the elements or objects listed following "comprising" or "including" and their equivalents, but do not exclude other elements or objects having the same function.

[0034] As shown in the figure, this embodiment provides a shielded dustproof and heat dissipation window, including a dustproof and heat dissipation window 1, a shielded waveguide window 2, and a waterproof heat dissipation plate 3, which are sequentially attached to each other. The waterproof heat dissipation plate 3 has several arrayed waterproof heat dissipation holes 31, which serve to prevent rainwater and provide ventilation and heat dissipation. The shielded waveguide window 2 is fixedly installed on the inner side of the waterproof heat dissipation plate 3. The shielded waveguide window 2 is a honeycomb waveguide window, consisting of a bundle of cutoff waveguides. The cross-sectional shapes of the cutoff waveguides are typically circular, square, and hexagonal. In this embodiment, preferably, its cross-sectional shape is hexagonal. The function of the shielded waveguide window 2 is to ensure airflow while simultaneously shielding the electromagnetic signals of the cabinet. The innermost side of the shielded dustproof and heat dissipation window 100 is provided with the dustproof and heat dissipation window 1, whose main function is to prevent dust from entering the airflow while maintaining airflow to aid in heat dissipation.

[0035] As shown in the figure, in a typical embodiment of this utility model, the dustproof heat dissipation window 1 adopts a rectangular window structure, including a rectangular combination frame composed of four side frames. At least one side frame 12 is provided with an opening groove 13, while the other side frames 12 without opening grooves 13 are provided with slots 14 along the length direction. Taking the slots 14 on three side frames 12 as an example, the three side slots 14 will form a U-shaped fixing slot structure for fixing the edge of the dustproof plate 11. The head end of the dustproof plate 11 can enter through the opening groove 13 and be inserted into the dustproof heat dissipation window 1 along the slots 14 on both sides. After installation, the head end, left and right sides of the dustproof plate 11 are fixedly engaged with the slots 14 on the three side frames 12, while the tail end of the dustproof plate 11 is still set in the position of the opening groove 13. The opening groove 13 is blocked by the baffle 15, thereby fixing the dustproof plate 11 inside the frame 12.

[0036] In this solution, to facilitate the installation of the dustproof heat dissipation window 1, the rectangular combined frame adopts a modular splicing design. Each side frame 12 is butted together but not directly fixed. Instead, each side frame 12 is connected and fixed to the shielded waveguide window 2 and the waterproof heat dissipation plate 3 respectively through connectors. After the four side frames 12 are joined together, a rectangular combined frame structure is formed. This design can reduce the installation difficulty to a certain extent. Only one operator is needed to quickly achieve modular assembly, and no welding is required.

[0037] In this solution, the combined frame can be implemented as follows: The combined frame includes a horizontal frame 121, two vertical frames 122, and an open frame 123. The horizontal frame 121 and the open frame 123 are arranged in parallel, and the two vertical frames 122 are arranged in parallel. The end faces of the two vertical frames 122 abut against the ends of the horizontal frame 121 and the open frame 123, thereby forming a rectangular frame structure. The horizontal frame 121 and the two vertical frames 122 have similar structures, each including a wide channel steel 124 and a narrow channel steel 125 that are parallel to each other. The wide channel steel 124 serves as the main body of the frame, and the groove of the narrow channel steel 125 serves as a slot 14. The slots of the wide channel steel 124 and the narrow channel steel 125 face away from each other and are fixedly connected by fitting the back of the base plate. The center lines of the wide channel steel 124 and the narrow channel steel 125 correspond to each other. The connection between the wide channel steel 124 and the narrow channel steel 125 can be achieved by welding, bonding, or fixing with bolts. To facilitate the joining of the corners of the frame, the narrow channel steel 125 of the two vertical frame 122 and the horizontal frame 121 forms a beveled angle 126 at its edge, thus facilitating seamless splicing at the corners and forming a right-angle structure. Considering the fixation of the two vertical frame 122 and the horizontal frame 121, a fixing through hole I4 is formed at the corresponding position of the wing plate of the wide channel steel 124. The function of the fixing through hole I4 is to allow the connector to pass through. The opening frame 123 is made of wide channel steel 124 with the same specifications as the vertical frame 122 and the horizontal frame 121. The bottom plate of the opening frame 123 has an opening groove 13 formed along its length. The wing plate of the opening frame 123 is provided with a fixing through hole I4 for the connector to pass through. The bottom plate of the opening frame 123 is also provided with a fixing through hole II5. The fixing through hole II5 is located at the periphery of the opening groove 13. An internal threaded part 16 is provided in the fixing through hole II5. The internal threaded part 16 is polygonal or toothed in shape, so as to adapt to the shape of the fixing through hole II5 and prevent the internal threaded part 16 from rotating relative to the fixing through hole II5. The function of the internal threaded part 16 is: the screw passes through the through hole 17 on the edge of the baffle 15 and is screwed into the internal threaded part 16 to realize the fixed connection between the baffle 15 and the opening frame 123, thereby realizing the sealing and fixing of the opening frame 123 by the baffle 15. The overlapping design of the slot 14 and the edge of the dustproof plate 11 can enhance the sealing performance of the edge of the dustproof plate 11, prevent airflow from passing through the gaps at the edge of the dustproof plate 11, and effectively guide the airflow through the dustproof cotton (dustproof net), so that it has a better dustproof effect.

[0038] In this design, the dustproof panel 11 includes an outer frame 111, fixing mesh 112, and a dustproof mesh (not shown in the figure). A double-layer fixing mesh 112 is fixedly arranged within the rectangular inner hole of the outer frame 111, with each layer of fixing mesh 112 having its four edges fixedly connected to the outer frame 111. A gap is formed between the two fixing meshes 112 for installing the dustproof mesh. The dustproof mesh can be made of polyurethane foam, which is used for air dust filtration. The fixing mesh 112 can be made of metal mesh to strengthen the external strength of the dustproof panel 11, effectively protecting the dustproof mesh. When maintenance or replacement of the dustproof mesh is required, the baffle 15 can be removed and the dustproof panel 11 can be pulled out for cleaning or replacement.

[0039] In this embodiment, in order to connect with the fixed through hole I4 of the dustproof heat dissipation window 1, the corresponding positions of the shielded waveguide window 2 and the waterproof heat dissipation plate 3 are provided with fixed through holes I4, so that the connecting parts can pass through the fixed through holes I4 in sequence and be fixedly connected as a whole.

[0040] This utility model also provides a power cabinet, including a cabinet body 6 and a cabinet door 7 hinged to the cabinet body 6. The cabinet body 6 is used to install power supplies, electrical control components, and wiring. Small wheels are provided at the bottom of the cabinet body 6. Preferably, the shielded dustproof heat dissipation window 10 is fixedly installed on the inner side of the air vent on the cabinet door 7. For ease of overall installation, the waterproof heat dissipation plate 3 and the cabinet door 7 can be designed as an integral unit, which facilitates production and processing, and also facilitates the installation and maintenance of the shielded dustproof heat dissipation window 10. Considering that the dustproof plate 11 and the electrical components on the cabinet door 7 should not interfere with each other, one side of the opening frame 123 can be placed at the top or bottom to facilitate the insertion or removal of the dustproof plate 11 at the opening slot 13, avoiding interference with the switches or electrical components on the cabinet door 7, and ensuring convenient replacement of the dustproof plate 11. The power cabinet in this solution can provide power for the electric servo mechanism and meet the specific requirements of power supply and communication. The power cabinet output and voltage regulation can be controlled by a host computer; and it also has a certain current limiting protection function.

[0041] In this embodiment, in order to enhance the heat dissipation effect of the power cabinet, shielded dustproof heat dissipation windows 10 are provided on the opposite side walls of the cabinet body 6. More specifically, the shielded dustproof heat dissipation windows 10 can be provided on the opposite cabinet doors 7 on both sides as opposite air vents, thereby enhancing the airflow heat exchange effect.

[0042] This solution takes into account the requirements of harsh operating environments for power supplies, especially those operating in deserts, sandy areas, and other environments, as well as equipment with electromagnetic compatibility requirements. It ensures that the power supply meets requirements for heat dissipation and protection. The shielded dustproof heat dissipation window 10's heat dissipation hole protection structure not only provides waterproofing and dustproofing but also meets electromagnetic compatibility requirements.

[0043] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to a preferred embodiment, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-disclosed technical content to create equivalent embodiments without departing from the scope of the present utility model.
