[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Refer to the instruction manual appendix Figures 1-5 This utility model provides a microenvironment control device for an electrical box, including a microenvironment control component 2 located at the bottom of the electrical box 1 and an exhaust component 3 located at the top of the electrical box 1. The microenvironment control component 2 includes a control box 21 connected to the interior of the electrical box 1. Inside the control box 21, from bottom to top, there are a blower 22, a support plate 23, a gas distributor 24, and a filter screen 25. The blower 22 is a Quanfeng RB-72S-5, and the gas distributor 24 is a Keding NK-590. The air outlet of the blower 22 is connected to the gas distributor 24 through a pipe 43. The gas distributor 24 is connected to the support plate 23 through a connecting component 4. The air inlet of the blower 22 is connected to the filter component 5.

[0025] Filter screen 25 serves a filtering function and also prevents components inside electrical box 1 from falling into control box 21.

[0026] In actual use, the blower 22 draws in outside air, which is then filtered by the filter assembly 5 and transported by the blower 22 and the pipe 43 to the gas distributor 24. The air is then sent from the gas distributor 24 and the filter screen 25 into the electrical box 1. The gas distributor 24 can effectively guide and distribute the air entering the electrical box 1. This uniformly distributed airflow field can interact more efficiently with the hot air in the electrical box 1, causing the hot air in the electrical box 1 to rise faster. Then the hot air is discharged through the shell 31 and the air supply pipe 32, realizing air circulation in the electrical box 1 and thus maintaining the microenvironment inside the electrical box 1.

[0027] In this embodiment, the exhaust assembly 3 includes a housing 31, with an air supply pipe 32 extending through the top of the housing 31. Both the air supply pipe 32 and the housing 31 are connected to the interior of the electrical box 1. Inside the housing 31, an exhaust fan 33 and a second filter screen 34 are installed sequentially from bottom to top. The second filter screen 34 is located below the air supply pipe 32. The exhaust fan 33 is an HDB1224HF. Using the exhaust fan 33 can accelerate the exhaust speed of hot air inside the electrical box 1. At the same time, the air supply pipe 32 is used to transport the hot air to a position away from the electrical box 1, so as to prevent the hot air from heating the surrounding environment of the electrical box 1 and affecting the heat dissipation effect. Furthermore, the second filter screen 34 can prevent dust and impurities in the air supply pipe 32 from flowing back into the electrical box 1.

[0028] In this embodiment, as Figure 3 As shown, the inner walls of both sides of the control box 21 are machined with sliding grooves 6. The support plate 23 is slidably inserted into the sliding groove 6 on the side near the sliding groove 6. The support plate 23 is fixed by the insertion method. When not in use, first disconnect the pipe 43 connected to the air outlet of the blower 22 (the pipe 43 can be connected to the air outlet of the blower 22 through a flange), and then pull the support plate 23 out from between the two sliding grooves 6. This facilitates the disassembly and maintenance of the gas distributor 24 by removing the connecting assembly 4.

[0029] Specifically, the connecting assembly 4 includes multiple collars 41 fixedly sleeved on the outside of the gas distributor 24. Each collar 41 has a support rod 42 detachably connected to its bottom end, and the support rod 42 is detachably connected to the top end of the support plate 23. By loosening the support rod 42 and the collar 41, the gas distributor 24 can be removed from the support plate 23.

[0030] Furthermore, a door panel 7 is hinged to the front end of the control box 21. The inner wall of the door panel 7 contacts the support plate 23 and the front end of the slide groove 6. A heat dissipation window 8 is installed at the front end of the door panel 7. A dustproof net is provided inside the heat dissipation window 8 to filter dust. The heat dissipation window 8 is connected to the inside of the control box 21 and is used for heat dissipation of the blower 22.

[0031] In this embodiment, specifically, the filter assembly 5 includes two semi-circular tubes 51, one end of which penetrates the outside of the control box 21. Multiple filter plates 52 are provided between the two semi-circular tubes 51, and desiccant, such as silica gel, alumina, calcium chloride, or other desiccants, is filled between adjacent filter plates 52. The use of desiccant can dehumidify the air to prevent humid air from corroding the electronic components inside the electrical box 1. Furthermore, arc-shaped shallow grooves 53 are machined on the inner walls of the two semi-circular tubes 51. The filter plates 52 are inserted into the arc-shaped shallow grooves 53. By loosening the two semi-circular tubes 51, the filter plates 52 can be removed, and the desiccant can be replaced at the same time.

[0032] Finally: The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
