Description

Technical Field

[0001] The utility model relates to the technical field of electrical cabinets, and particularly relates to an electrical cabinet for electronic engineering. Background Art

[0002] With the development of industrialization and informatization, the demand for electrical equipment is increasing day by day, especially in fields such as the manufacturing industry, the energy industry, and data centers. As the core component of the power distribution, control equipment, and communication system, the electrical cabinet for electronic engineering is widely used in industrial automation, data centers, and building power distribution and other fields. These industries have extremely high requirements for the stability, reliability, and safety of the electrical system, thus promoting the progress and development of electrical cabinet technology.

[0003] Traditional electrical cabinets are usually equipped with a flat fixed filter structure. This design is prone to clogging of the pores on the surface of the filter by suspended particulate matters such as dust and catkins. Especially in industrial dust environments or sandy areas, the cleaning cycle of the filter is significantly shortened. Once the filter is clogged, the air intake volume will be greatly reduced, resulting in a significant increase in the temperature inside the cabinet, far exceeding the design expectation. This situation will not only affect the working efficiency and stability of electrical equipment, but also shorten its service life. Therefore, we designed an electrical cabinet for electronic engineering to improve the heat dissipation performance and dust prevention ability of the electrical cabinet and ensure the long-term stable operation of the equipment. Content of the Utility Model

[0004] In order to overcome the above-mentioned shortcomings of the prior art, an electrical cabinet for electronic engineering is provided.

[0005] The technical solution of the utility model is as follows: An electrical cabinet for electronic engineering, comprising a cabinet body and a heightening frame. The cabinet body is the assembly main body of this electrical cabinet. A cabinet door is hinged at the front opening of the cabinet body. A heightening frame for lifting is fixedly arranged at the bottom of the cabinet body. Ventilation openings are opened on the circumferential side walls of the frame body of the heightening frame. It also includes a first filter screen, a first installation frame, an intake fan, a second installation frame, an exhaust fan, and a filter frame. The first filter screens are installed at the ventilation openings of the heightening frame. The first filter screens are used to block foreign objects from entering the heightening frame. An air intake is opened at the bottom of the cabinet body. A first installation frame is fixedly embedded at the air intake of the cabinet body. A plurality of intake fans are assembled inside the first installation frame. The intake fans blow air into the cabinet body. A second installation frame is fixedly arranged at the top of the solid. A plurality of exhaust fans are assembled inside the second installation frame. The exhaust fans blow air outside the cabinet body. A filter frame is slidably connected to the bottom of the cabinet body through a guide rod. The filter frame is slidably sleeved outside the first installation frame. A spring is arranged between the cabinet body and the first installation frame. The filter holes of the filter frame are smaller than those of the first filter screen and are used for filtering dust. A vibrating member for vibrating the filter frame is arranged inside the heightening frame.

[0006] In one embodiment, a second filter screen is circumferentially arranged on the side wall of the frame body of the second installation frame. The second filter screen is used to prevent foreign objects from entering the cabinet body in the reverse direction from the second installation frame, reducing the heat dissipation pressure of the exhaust fan.

[0007] In one embodiment, the vibrating member includes a motor and a cam. One side of the frame body of the filter frame is fixedly connected with a connecting plate. The connecting plate protrudes outward from the side wall of the filter frame. The motor is fixedly installed on the inner wall of the heightening frame. The output shaft of the motor is fixedly connected with the cam. The cam contacts the connecting plate. The motor drives the cam to intermittently press the connecting plate, and cooperates with the spring to reset the filter frame on the first installation frame, so that the filter frame can vibrate irregularly, thereby shaking off the dust filtered on the filter frame.

[0008] In one embodiment, both the intake fan and the exhaust fan are detachably assembled inside the first installation frame and the second installation frame. After the intake fan and the exhaust fan are removed, it is convenient to carry out maintenance.

[0009] In one embodiment, a dust exhaust fan is further included. A plurality of dust exhaust fans are arranged on one side of the frame body of the heightening frame. The dust exhaust fans are lower than the bottom filter screen of the filter frame. The dust exhaust fans blow air from the inside of the heightening frame to the outside, so that the dust shaken off from the filter frame is sucked away and discharged by the dust exhaust fans, preventing dust from accumulating in the heightening frame at the bottom of the cabinet body.

[0010] In one embodiment, a support plate is fixedly installed inside the cabinet body. A temperature sensor is installed on the support plate. The temperature sensor is specifically an infrared sensor and measures the temperature of the electrical components in the cabinet body through the infrared radiation amount. A display screen is arranged on the inner wall of the cabinet body near the temperature sensor. The temperature sensor is electrically connected to the display screen. The display screen is used to display the temperature inside the cabinet body monitored by the temperature sensor.

[0011] The beneficial effects of the present utility model:

[0012] 1. The present utility model sucks external air into the cabinet body through the intake fan and discharges the hot air through the top exhaust fan, forming a circulating air duct from bottom to top, improving the heat dissipation efficiency of the electrical components in the cabinet body. The vibrating member can shake off the dust accumulated on the filter frame, avoiding blockage and maintaining good heat dissipation and ventilation performance.

[0013] 2. The present utility model can suck away and discharge the shaken-off dust from the heightening frame by arranging the additional dust exhaust fans lower than the bottom of the filter frame, preventing dust from accumulating at the bottom of the cabinet body, reducing the need for manual cleaning. At the same time, the second filter screen arranged around the second installation frame can prevent foreign objects from the outside from entering the cabinet body in the reverse direction from the exhaust port, reducing the working burden of the exhaust fan and improving the stability and service life of the overall system.

[0020] The present utility model will be further described below in conjunction with the drawings and specific embodiments. To make the purpose, technical solutions and advantages of the present utility model clearer, the present utility model will be further described in detail below in conjunction with the drawings. It is hereby declared that the orientation terms such as up, down, left, right, front, back, inside and outside that appear or will appear in the text of the present utility model are only based on the drawings of the present utility model, and they do not specifically limit the present utility model.

[0021] An electrical cabinet for electronic engineering, such as Figures 1 - 4As shown in the figure, it includes a cabinet body 1 and a heightening frame 3. The cabinet body 1 is the main assembly of this electrical cabinet. A cabinet door 2 is hinged at the front opening of the cabinet body 1. A heightening frame 3 for lifting is fixedly installed at the bottom of the cabinet body 1. Ventilation openings are provided on the circumferential side walls of the frame body of the heightening frame 3. It also includes a first filter screen 4, a first installation frame 5, an intake fan 6, a second installation frame 7, an exhaust fan 8, and a filter frame 10. First filter screens 4 are installed at the ventilation openings of the heightening frame 3. The first filter screens 4 are used to block foreign objects from entering the heightening frame 3. An intake port is provided at the bottom of the cabinet body 1. A first installation frame 5 is fixedly embedded at the intake port of the cabinet body 1. A plurality of intake fans 6 are assembled inside the first installation frame 5. The intake fans 6 blow air into the cabinet body 1. A second installation frame 7 is fixedly installed at the top of the solid body. A plurality of exhaust fans 8 are assembled inside the second installation frame 7. The exhaust fans 8 blow air out of the cabinet body 1. A filter frame 10 is slidably connected to the bottom of the cabinet body 1 through a guide rod 11. The filter frame 10 is slidably sleeved outside the first installation frame 5. A spring 12 is provided between the cabinet body 1 and the first installation frame 5. The filter holes of the filter frame 10 are smaller than those of the first filter screen 4 and are used to filter dust. A vibrating member for vibrating the filter frame 10 is provided inside the heightening frame 3. The intake fans 6 are used to draw in cooling air into the cabinet body 1, and in cooperation with the exhaust fans 8, the cooling air is discharged, so that a circulating cooling air duct is formed from the bottom to the top inside the cabinet body 1. When dissipating heat, the first filter screens 4 at the heightening frame 3 initially block large foreign objects, and then the filter frame 10 filters the dust brought in by the air flow. At the same time, in cooperation with the vibrating member, the dust on the filter frame 10 is shaken off synchronously, avoiding blockage of the filter frame 10 and ensuring a good air intake effect of the filter frame 10, and reducing the frequency of manual maintenance and cleaning.

[0022] As Figure 1 and Figure 2 shown, a second filter screen 9 is circumferentially arranged on the side wall of the frame body of the second installation frame 7. The second filter screen 9 is used to block foreign objects from entering the cabinet body 1 in the reverse direction from the second installation frame 7, reducing the heat dissipation pressure of the exhaust fans 8.

[0023] As Figure 2 and Figure 3 shown, the vibrating member includes a motor 13 and a cam 14. A connecting plate 101 is fixedly connected to one side of the frame body of the filter frame 10. The connecting plate 101 protrudes outward from the side wall of the filter frame 10. The motor 13 is fixedly installed on the inner wall of the heightening frame 3. A cam 14 is fixedly connected to the output shaft of the motor 13. The cam 14 is in contact with the connecting plate 101. The motor 13 drives the cam 14 to intermittently press the connecting plate 101, and in cooperation with the spring 12, the filter frame 10 is reset on the first installation frame 5, realizing that the filter frame 10 can vibrate irregularly, thereby shaking off the dust filtered on the filter frame 10.

[0024] As Figure 2 shown, both the intake fans 6 and the exhaust fans 8 are detachably assembled inside the first installation frame 5 and the second installation frame 7. After the intake fans 6 and the exhaust fans 8 are removed, it is convenient for maintenance.

[0025] like Figure 2 As shown, a dust exhaust fan 15 is also included. Multiple dust exhaust fans 15 are arranged on one side of the frame of the elevated frame 3. The dust exhaust fan 15 is lower than the bottom filter screen of the filter frame 10. The dust exhaust fan 15 blows air from the inside of the elevated frame 3 to the outside, so that the dust shaken off the filter frame 10 is sucked away and discharged by the dust exhaust fan 15, preventing dust from accumulating in the elevated frame 3 at the bottom of the cabinet 1.

[0026] like Figure 2 and Figure 4 As shown, a support plate 16 is fixedly provided inside the cabinet 1, and a temperature sensor 17 is installed on the support plate 16. The temperature sensor 17 is specifically an infrared sensor and measures the temperature of electrical components in the cabinet 1 through infrared radiation. A display screen 18 is provided on the inner wall of the cabinet 1 near the temperature sensor 17. The temperature sensor 17 and the display screen 18 are electrically connected. The display screen 18 is used to display the temperature in the cabinet 1 monitored by the temperature sensor 17.

[0027] When using the electrical cabinet, the air intake fan 6 in the frame 15 installed at the bottom of the cabinet 1 is activated, and the external air is initially filtered by the filter 14 of the heightened frame 3, and then finely filtered by the filter frame 10. The clean air passes through the internal space of the cabinet 1 upward, and the exhaust fan 8 of the frame 27 installed on the top of the cabinet 1 is synchronized to form a negative pressure. The hot air is discharged through the filter 29, and a directional air duct from bottom to top is constructed. The double protection of the filter 29 prevents the backflow of external foreign matter and avoids the formation of air flow short circuit at the exhaust end. During the filtering process, the vibration motor 13 drives the cam 14 to periodically press the connecting plate 1 01, so that the filter frame 10 generates high-frequency micro-vibration along the guide rod 11, and its amplitude is adjusted by the spring 12 to form an effective dust-shaking action. At this time, the dust exhaust fan 15 group on the side wall of the heightening frame 3 is started synchronously, and a local negative pressure area is formed under the filter frame 10, and the shaken dust particles are sucked out through an independent air duct. For the convenience of maintenance, the air intake fan 6, the exhaust fan 8 and the dust exhaust fan 15 are designed to be detachable, which is convenient for users to clean or replace. The infrared temperature sensor 17 in the cabinet monitors and displays the component temperature in real time. When the temperature is abnormal, the fan speed can be adjusted or an early warning can be issued.
