Description

Technical Field

[0001] This utility model relates to the field of electrical control equipment technology, specifically to a constant temperature device for an electrical control box. Background Technology

[0002] An electrical control box is a sealed metal enclosure used to install and protect electrical equipment. It is typically used to house power control systems, electronic equipment, or other related devices, ensuring their proper operation and protection even in harsh environments. Electrical control boxes are usually dustproof, waterproof, and corrosion-resistant, effectively isolating the internal equipment from external environmental influences. Furthermore, they provide safety protection, preventing personnel from being injured by contact with high-voltage electrical components. In the industrial sector, electrical control boxes are widely used in various equipment and systems, such as automated production lines, power generation equipment, and power transmission and distribution systems. Through the electrical control box, users can centrally manage and monitor equipment, ensuring its stable and reliable operation. Temperature within the electrical control box is a crucial parameter; appropriate temperatures ensure the normal operation of electrical equipment and extend its lifespan. Generally, the optimal operating temperature range for most electrical control boxes is between 20 and 40 degrees Celsius. Within this range, the electrical components and equipment inside the control box can operate normally without overheating or cooling.

[0003] The electrical control box in the connector currently in use has the following technical problems: In order to maintain the temperature inside the box, existing electrical control boxes usually use appropriate ventilation facilities and temperature monitoring systems to effectively control and regulate the internal temperature of the electrical control box. Among them, the ventilation facilities generally use fans to cool down the electrical components inside the box. However, this ventilation method causes the air to come into direct contact with the electrical components. When the outside temperature is too high or too low, the temperature of the air carried by the fan will cause the temperature inside the electrical control box to be too high or too low, which will affect the normal operation of the electrical equipment and reduce the service life of the equipment. Utility Model Content

[0004] This utility model proposes a constant temperature device for an electrical control box, which enables heat exchange between the airflow and the electrical components, thereby maintaining a constant temperature environment for the electrical components, ensuring the normal operation of the electrical equipment and extending its service life.

[0005] The technical solution of this utility model is as follows:

[0006] A temperature control device for an electrical control box includes an electrical control box body. A partition is fixedly connected inside the electrical control box body. A first protective sleeve is fixedly connected between the partition and the bottom wall of the electrical control box body. A wall-mounted fan is connected between the first protective sleeve and the partition. Air guide plates are fixedly connected to the inner walls on both sides of the electrical control box body. A door panel is hinged to the outer side of the electrical control box body. A linkage component for temperature control protection of the components inside the electrical control box body is connected between the door panel and the electrical control box body.

[0007] Furthermore, the linkage component includes a slide rail, which is fixedly connected to the bottom wall of the electrical control box. A slider is slidably connected on the slide rail, and a linkage plate is fixedly connected to the slider. A first flip plate is hinged to the end of the linkage plate facing the door panel, and a first flip block is hinged to the end of the first flip plate away from the linkage plate. The first flip block is fixedly connected to the door panel. A second flip plate is hinged to the end of the linkage plate away from the first flip plate, and a second flip block is hinged to the end of the second flip plate away from the linkage plate. A limit plate is fixedly connected to one side of the second flip block.

[0008] Furthermore, a working plate is fixedly connected to the limiting plate, and the side of the working plate away from the door panel is flush with the side of the limiting plate away from the second flip block. Several limiting posts are slidably connected to the limiting plate, and each limiting post is fixedly connected to the first protective sleeve.

[0009] Furthermore, a cooling groove is provided on the side of the working plate facing the limiting plate.

[0010] Furthermore, the air guide plate is provided with several air guide grooves.

[0011] Furthermore, the first protective sleeve has an air inlet slot and an air outlet slot on its upper and lower sides, respectively, and the air outlet of the wall-mounted fan is connected to the air inlet slot and the air outlet slot.

[0012] Furthermore, a second protective sleeve is fixedly connected to the door panel, and the inner sidewall of the second protective sleeve abuts against the outer sidewall of the working board.

[0013] Furthermore, a handle is fixedly connected to the side of the door panel away from the second protective sleeve.

[0014] The beneficial effects of this utility model are as follows:

[0015] The linkage component is connected between the door panel and the electrical control box. Users control the operation of the linkage component by opening and closing the door panel. When the door panel is closed, a constant temperature cavity is formed between the working plate and the second protective sleeve. The wall-mounted fan cools the outer wall of the working plate, indirectly reducing the temperature of the components inside the working plate. This ensures that the cold air does not directly contact the components, so that the components are neither too cold nor too hot, and are always kept within a certain temperature range. This helps to ensure the normal operation of electrical equipment and extend the service life of the equipment. Attached Figure Description

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

[0024] like Figures 1-5As shown, this embodiment proposes a temperature control device for an electrical control box, including an electrical control box 26, a partition 27 fixedly connected inside the electrical control box 26, and a space above the partition 27 for installing components such as buttons and a display screen. A first protective sleeve 22 is fixedly connected between the partition 27 and the bottom wall of the electrical control box 26. A wall-mounted fan 28 is connected between the first protective sleeve 22 and the partition 27. The wall-mounted fan 28 draws in the air above the partition 27 and blows it downwards, making the air inside the entire electrical control box 26 circulate. Two air guide plates 21 are fixedly connected to the inner walls on both sides of the electrical control box 26, respectively. The two air guide plates 21 guide the passing cold air, so that the guided air can cool the side wall of the working plate 19, increasing the cooling effect on the working plate 19. The cooling effect is achieved by hinges connecting the outer side of the electrical control box 26 to the door panel 25. The linkage component 1, which provides constant temperature protection for the components inside the electrical control box 26, is connected between the door panel 25 and the electrical control box 26. The user opens and closes the door panel 25 to activate the linkage component 1. When the door panel 25 is closed, the components inside the electrical control box 26 are covered by the working plate 19 and the second protective sleeve 24. The temperature of the components inside the working plate 19 is indirectly reduced by cooling the outer wall of the working plate 19 through the wall-mounted fan 28. This prevents the cold air from directly contacting the components, keeping the cavity temperature between the working plate 19 and the second protective sleeve 24 stable, thereby enabling the components to work in a constant temperature environment.

[0025] like Figures 2-4 As shown, the linkage assembly 1 includes a slide rail 18, which is fixedly connected to the bottom wall of the electrical control box 26. The slide rail 18 is slidably connected to the slider 17. The linkage plate 13 is fixedly connected to the slider 17. The end of the linkage plate 13 facing the door panel 25 is hinged to the first flip plate 12. The end of the first flip plate 12 away from the linkage plate 13 is hinged to the first flip block 11. The first flip block 11 is fixedly connected to the door panel 25. The end of the linkage plate 13 away from the first flip plate 12 is hinged to the second flip plate 16. The end of the second flip plate 16 away from the linkage plate 13 is hinged to the second flip block 14. The limiting plate 15 is fixedly connected to the first flip plate 16. On one side of the second flip block 14, when the door panel 25 flips towards the electrical control box 26, it will move the linkage plate 13 along the long side of the slide rail 18, and then the second flip plate 16 will bring out the limit plate 15, so that the second protective sleeve 24 can cover the working plate 19. When the door panel 25 flips in the opposite direction to the electrical control box 26, that is, when the components need to be debugged or maintained, the door panel 25 will move along with the linkage plate 13, and the second protective sleeve 24 will separate from the working plate 19, so as to facilitate the debugging and replacement of the components in the working plate 19.

[0026] like Figures 2-4As shown, the working plate 19 is fixedly connected to the limiting plate 15. The working plate 19 is used to install components. The side of the working plate 19 away from the door panel 25 is flush with the side of the limiting plate 15 away from the second flip block 14. Several limiting posts 23 are slidably connected to the limiting plate 15. Each limiting post 23 is fixedly connected to the first protective sleeve 22, so that the working plate 19 can move back and forth on the limiting posts 23 through the limiting plate 15.

[0027] like Figure 2 and Figure 5 As shown, the cooling groove 191 is formed on the side of the working plate 19 facing the limiting plate 15. The cooling groove 191 increases the contact area between the side of the working plate 19 and the air, thereby increasing the cooling effect of the working plate 19.

[0028] like Figures 2-5 As shown, several air guide slots 211 are formed on the air guide plate 21 to guide the air passing through the air guide plate 21, so that the air can exchange heat with the outer wall of the working plate 19 along the air guide slots 211, thereby cooling the working plate 19.

[0029] like Figures 2-5 As shown, the air inlet slot 221 and air outlet slot 222 are respectively located on the upper and lower sides of the first protective sleeve 22. The air outlet of the wall-mounted fan 28 is connected to the air inlet slot 221 and air outlet slot 222. The wall-mounted fan 28 blows downwards. When the working plate 19 abuts against the inner wall of the first protective sleeve 22, that is, when the door panel 25 is open, the air duct cavity between the air inlet slot 221 and air outlet slot 222 is cut off by the working plate 19. Therefore, the air will flow to both sides along the upper side of the first protective sleeve 22, and part of the airflow will flow towards the door panel 25, providing air to the currently... The equipment components are cooled during debugging. When the working plate 19 is separated from the inner wall of the first protective sleeve 22, that is, when the door plate 25 is closed, the air duct cavity between the air inlet slot 221 and the air outlet slot 222 is connected. By cooling the outer surface of the working plate 19, the components installed in the working plate 19 are cooled. At the same time, the air does not come into direct contact with the components, so the components will not be overcooled, and the dust carried by the air will not affect the components. Thus, the temperature of the components is kept within a certain temperature range, achieving a constant temperature effect.

[0030] like Figure 3 and Figure 4 As shown, the second protective sleeve 24 is fixedly connected to the door panel 25. The inner side wall of the second protective sleeve 24 abuts against the outer side wall of the working plate 19, so that after the door panel 25 and the electrical control box 26 are closed, the second protective sleeve 24 can cover the working plate 19 and reduce the impact of dust on the components.

[0031] like Figure 1 As shown, the handle 29 is fixedly connected to the side of the door panel 25 away from the second protective sleeve 24, and the user can open and close the door panel 25 by using the handle 29.

[0032] The working principle of this embodiment is as follows:

[0033] After the user has installed and debugged the components on the work plate 19, they can then use the handle 29 to close the door panel 25. As the door panel 25 closes towards the electrical control box 26, the first flip plate 12 applies force to the linkage plate 13, causing the slider 17 to slide to one side along the slide rail 18. This causes the second flip plate 16 to move the limiting plate 15, which then moves along the limiting post 23. After the door panel 25 is fully closed, the first protective sleeve 22 will protrude from the side of the work plate 19 facing the door panel 25, simultaneously opening the air inlet sill. The cavity space between 221 and the air outlet slot 222 is open, and the cold air blown by the wall-mounted fan 28 will quickly pass through the cavity, which will quickly exchange the temperature on the side wall of the cavity, thereby cooling the working plate 19. The heat generated by the components on the working plate 19 will be continuously carried away by the cold air. At the same time, the closing of the door panel 25 will cover the working plate 19 with the second protective sleeve 24, preventing the outside cold air from directly cooling the components. This ensures that the cavity temperature between the second protective sleeve 24 and the working plate 19 is maintained within a certain temperature range, thereby achieving a constant temperature effect on the components.

[0034] The above are merely preferred embodiments of the present utility model and are 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 shall be included within the protection scope of the present utility model.
