Abstract
Description
Technical Field
[0001] This utility model belongs to the field of dustproof and heat dissipation of electrical cabinets, and particularly relates to a dustproof and heat dissipation device and an electrical cabinet. Background Technology
[0002] Traditional electrical cabinet designs typically use fixed louvers for ventilation. When the ventilation fans stop running, ambient dust can easily fall into the cabinet through the louvers, corroding internal components, reducing system safety, and even increasing the risk of fire. This dust may include metal shavings, dust, and chemical particles, which are suspended in the air and enter the louver gaps with breezes or airflows, gradually accumulating on the surfaces of circuit boards and electronic components, forming a thick layer of grime. This grime not only increases the resistance of the equipment, causing overheating, but can also trigger short circuits, further increasing the fire risk. Furthermore, the corrosive components in the dust accelerate equipment aging, shorten its lifespan, and increase maintenance costs and downtime.
[0003] Therefore, there is an urgent need to design a dustproof and heat dissipation device to solve the problems mentioned above. Utility Model Content
[0004] To address the technical problem mentioned in the background art of dust corroding equipment components inside the cabinet and reducing system safety, a dustproof heat dissipation device and an electrical cabinet are provided.
[0005] To achieve the above objectives, the specific technical solution of this utility model for a dustproof heat dissipation device and electrical cabinet is as follows:
[0006] A dustproof and heat dissipation device includes a mounting bracket and further includes:
[0007] The dustproof assembly includes a sliding rod and a dust cover. The sliding rod is located at the center of the fixed frame and is slidably connected to the dust cover, which is a plate-shaped cone.
[0008] The heat dissipation component is installed at the bottom of the mounting bracket and is used to output cooling air to the dust cover.
[0009] Furthermore, the dustproof and heat dissipation device also includes an adjustment component, which is mounted on a sliding rod and is used to adjust the position of the dust cover in conjunction with the heat dissipation air.
[0010] Furthermore, the adjustment assembly includes two stops, both of which are mounted on the sliding rod, and the two stops are respectively mounted on both sides of the dust cover to limit the position of the dust cover.
[0011] Furthermore, the adjustment assembly also includes an elastic element, one end of which is connected to the dust cover and the other end of which is connected to the stop element.
[0012] Furthermore, an air outlet is formed between the heat dissipation components and the dust cover, and the cooling air leaves the dust-proof heat dissipation device through the air outlet.
[0013] Furthermore, from the heat dissipation component to the top of the mounting bracket, the cross-sectional area of the dust cover gradually decreases.
[0014] Furthermore, the mounting bracket includes a cable guide hole located on the side of the mounting bracket, through which the cables of the heat dissipation component pass.
[0015] An electrical cabinet uses the aforementioned dustproof and heat dissipation device, which is located on the top of the electrical cabinet.
[0016] Furthermore, the bottom of the electrical cabinet is equipped with an air inlet. Cooling air enters the cabinet through the air inlet and is then output through the heat dissipation components.
[0017] Furthermore, the top of the electrical cabinet is also equipped with several lifting lugs, which are located at the corners of the top of the electrical cabinet.
[0018] The dustproof and heat dissipation device of this utility model has the following advantages: the dustproof and heat dissipation device uses a dustproof cover to open and close through a sliding connection.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.
[0028] Those skilled in the art will understand that although some embodiments herein include certain features included in other embodiments but not others, combinations of features from different embodiments are intended to be within the scope of this invention and form different embodiments. For example, in the claims, any of the claimed embodiments can be used in any combination.
[0029] The following is a reference to the appendix. Figure 1 To be continued Figure 5 This invention describes a dustproof and heat dissipation device and an electrical cabinet.
[0030] Example 1:
[0031] This embodiment provides a dustproof and heat dissipation device. Figure 1 This is a schematic diagram of the electrical cabinet in this embodiment; Figure 2 for Figure 1 A magnified view of a section at point A in the middle; Figure 3 This is a schematic diagram of the dustproof and heat dissipation device according to the first embodiment; as shown. Figures 1-3 As shown, the dustproof and heat dissipation device includes a fixed frame 1, a dustproof component 2, and a heat dissipation component 3. The dustproof component 2 includes a sliding rod 21 and a dust cover 22. The sliding rod 21 is located at the center of the fixed frame 1 and is slidably connected to the dust cover 22. The dust cover 22 is in the shape of a plate cone. The heat dissipation component 3 is installed at the bottom of the fixed frame 1 and is used to output heat dissipation air to the dust cover 22.
[0032] The dustproof and heat dissipation device uses a dust cover 22 to open and close via a sliding connection. When the fan is running, it automatically opens the heat dissipation channel and closes when it stops to prevent dust from entering. The plate-shaped conical design guides the airflow to be concentrated and discharged, reducing wind resistance and improving heat dissipation efficiency. The conical dust cover 22 will not easily get stuck when it moves up and down, and the surrounding force is directed inward. The fixing frame 1 integrates the dustproof and heat dissipation components 3, which is convenient for installation and maintenance.
[0033] Furthermore, such as Figure 2 and Figure 3 As shown, the dustproof and heat dissipation device also includes an adjustment component 4, which is mounted on the sliding rod 21 and used to adjust the position of the dust cover 22 in conjunction with the cooling fan. The adjustment component 4 can automatically adjust the specific position of the dust cover 22 according to actual needs, balancing dust prevention and heat dissipation requirements. This prevents the dust cover 22 from being excessively opened when the fan is running at full power, thus avoiding energy waste.
[0034] Specifically, such as Figure 3 As shown, the adjusting assembly 4 includes two stops 41, both mounted on the sliding rod 21, and the two stops 41 are respectively located on both sides of the dust cover 22 to limit the position of the dust cover 22. The stops 41 can prevent the dust cover 22 from falling off the slide rail or from not closing properly in strong winds; the two side stops 41 prevent the dust cover 22 from wearing on one side and extend its service life.
[0035] Furthermore, an air outlet is formed between the heat dissipation component 3 and the dust cover 22, and the heat dissipation air leaves the dust-proof heat dissipation device through the air outlet.
[0036] Furthermore, from the top of the heat dissipation component 3 to the top of the mounting bracket 1, the cross-sectional area of the dust cover 22 gradually decreases. The conical structure creates a Venturi effect, accelerating the exhaust of hot air. The tapered design increases the dust adhesion area, reducing the amount of particulate matter entering the cabinet.
[0037] Furthermore, such as Figure 3 As shown, the mounting bracket 1 includes a cable passage hole 5, which is located on the side of the mounting bracket 1. The cables of the heat dissipation component 3 pass through the cable passage hole 5. The design of the cable passage hole 5 can prevent the cables from getting tangled and interfering with the movement of the dust cover 22; and the centralized wiring reduces the risk of line wear and short circuits.
[0038] Example 2:
[0039] Figure 4 This is a schematic diagram of the dustproof and heat dissipation device according to the second embodiment; Figure 5 This is a side view of the dustproof and heat dissipation device according to the second embodiment.
[0040] This embodiment provides a dustproof and heat dissipation device, such as... Figure 4 and Figure 5As shown, the dustproof heat dissipation device is basically the same as the dustproof heat dissipation device in Embodiment 1 above. The difference is that the adjustment component 4 of the dustproof heat dissipation device also includes an elastic member 42. One end of the elastic member 42 is connected to the dust cover 22, and the other end is connected to the stop member 41.
[0041] By utilizing the weight of the dust cover 22 in conjunction with the elastic element 42, the demand on the elastic force of the elastic element 42 is reduced; the upper force-bearing design prevents the dust cover 22 from tilting and ensures that the opening and closing trajectory is vertical; in addition, the conical dust cover 22 can vibrate during the up and down movement, making it less likely for dust to accumulate on the top of the dust cover 22 and reducing energy loss.
[0042] Example 3:
[0043] This embodiment provides an electrical cabinet, such as Figure 1 and Figure 2 As shown, the dustproof and heat dissipation device of Embodiment 1 or Embodiment 2 described above is used, wherein the dustproof and heat dissipation device is installed on the top of the electrical cabinet.
[0044] The electrical cabinet allows hot air to rise naturally, and with the active exhaust system, it creates efficient convection. The top protection blocks the main entry path of dust (in the traditional louvered area). When the cooling fan stops working, the air outlet closes, preventing dust from entering the cabinet through the vents. This design extends the lifespan of electrical components and ensures the safety of the electrical system.
[0045] Furthermore, the bottom of the electrical cabinet is equipped with an air inlet 6 for the cabinet body 8. The cooling air enters the cabinet body 8 through the air inlet 6 and is then output through the heat dissipation component 3. The bottom air intake and top exhaust form a vertical circulation to avoid airflow short-circuiting; a pre-filter can be installed at the bottom air inlet to further reduce dust load.
[0046] Furthermore, such as Figure 1 and Figure 2 As shown, the top of the electrical cabinet is also equipped with several lifting lugs 7, which are located at the corners of the top of the electrical cabinet. The lifting lugs 7 are integrated with the dustproof and heat dissipation device, facilitating overall hoisting and transportation. They also distribute the stress on the top of the cabinet 8, preventing deformation of the device during installation.
[0047] It is understandable that, such as Figure 1 and Figure 2 As shown, the electrical cabinet includes a cabinet body 8, which is provided with a cabinet body 8 door panel, a cabinet body 8 lock, a cabinet body 8 base, and a cable passage 84 provided on the cabinet body 8 base. The above structures are all conventional technical means for those skilled in the art. How to set them up is the prior art, and this embodiment will not make any further details.
[0048] The method of using this dustproof and heat dissipation device is as follows:
[0049] When the electrical cabinet is running, the heat dissipation component 3 outputs cooling air upwards through the air inlet 6 of the cabinet 8. The upward flow of the cooling air blows the dust cover 22 up. The height of the dust cover 22 is adjusted by the upper limit of the sliding rod 21, preventing dust from entering the interior of the cabinet 8 and achieving normal heat dissipation. When the electrical cabinet stops working, the cooling fan stops rotating and blows air upwards, and the dust cover 22 falls due to gravity. The lower limit of the sliding rod 21 is adjusted to adjust the falling position, thereby adjusting the relative position of the dust cover 22 and the heat dissipation component 3 to achieve a complete contact effect, preventing dust from entering the interior of the cabinet 8. Depending on the working status of the cooling fan, the dust cover 22 reciprocates on the sliding rod 21, thereby improving the dust prevention effect.
[0050] Obviously, the above embodiments of this utility model are merely examples for clearly illustrating the present utility model, and are not intended to limit the implementation of the present utility model. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of this utility model should be included within the protection scope of the claims of this utility model.
