Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] See also Figure 1-Figure 6 The utility model provides a technical solution: a composite electrical and electronic engineering control cabinet, including a cabinet body 1 and a heat sink 2.

The setting of the four bases 3 further enhances the stability of the entire control cabinet and ensures the smooth operation of the electrical components.

[0030] A heat dissipation mechanism is provided inside the cabinet 1;

[0031] The heat dissipation mechanism includes a ventilation unit and a heat dissipation unit;

[0032] The ventilation unit includes a bellows 4, an air pump 401, a door 402, a handle 403, a ventilation duct 404, a second filter 405, a frame 406, a bracket 7 and a vent 701. The bottom of the bellows 4 is fixedly connected to the upper surface of the cabinet 1 at the rear. The bellows 4 is the core part of the ventilation system. The bellows 4 can collect and guide air into the interior of the cabinet 1 to achieve air circulation. The door 402 is hinged to the left and right sides of the upper surface of the bellows 4. The handle 403 is fixedly connected to the middle of the upper surface of the door 402, which is convenient for opening the door 402 and maintaining or replacing the air pump 401 and the ventilation duct 404. The air outlet of the air pump 401 is fixedly connected to the front of the door 402. The air pump 401 provides power to suck the external air into the bellows 4 and push it into the interior of the cabinet 1 to enhance the heat dissipation effect. One end of the ventilation duct 404 is fixedly connected to both sides of the bellows 4, the frame 406 is fixedly connected to both sides of the inside of the bellows 4, the second filter 405 is movably connected to the inside of the frame 406, the diameter of the second filter 405 is smaller than the diameter of the frame 406, and the second filter 405 directly filters impurities in the air to ensure that the air entering the cabinet 1 is clean. The design of the frame 406 is convenient for replacing the filter. A through opening is provided on the upper surface of the bellows 4, and the top of the frame 406 fits the opening tightly. The bracket 7 is fixedly connected to the back of the inside of the cabinet 1, and the ventilation hole 701 is provided on the front of the bracket 7. The inside of the bracket 7 is a hollow structure. There are multiple ventilation holes 701, which are equidistantly arranged on the front of the bracket 7. The bracket 7 provides support for the ventilation duct 404, and the ventilation holes 701 thereon ensure that the air can be evenly distributed inside the cabinet 1, thereby improving the heat dissipation effect. The other end of the ventilation duct 404 is fixedly connected to the top of both sides of the bracket 7 and extends downward, guiding the air in the bellows 4 to the inside of the cabinet 1, ensuring that the air is evenly distributed and improving the heat dissipation efficiency;

[0033] The heat dissipation unit includes a heat dissipation fan 6, a shutter 5, and a heat sink 8. The heat dissipation fan 6 is fixedly connected to the upper part of both sides of the cabinet 1. Through forced convection, the heat inside the cabinet 1 is quickly discharged to enhance the heat dissipation effect. The shutter 5 is opened at the lower part of both sides of the cabinet 1 to prevent external impurities from entering the cabinet while allowing air flow, thereby playing a protective role. The heat sink 8 is fixedly connected to the middle part of the lower surface of the cabinet 1 to increase the heat dissipation area, improve the heat dissipation efficiency, and ensure the normal operation of the electrical components.

[0034] The cabinet body 1 has cabinet doors 101 hingedly connected to the left and right sides of the front, and a handle 102 fixedly connected to the middle of the front of the cabinet door 101. The cabinet door 101 is designed to facilitate opening the control cabinet for installation, debugging and maintenance of internal components. The handle provides a convenient opening method and improves the user experience.

[0035] Working principle: Place the control cabinet in an appropriate position, open the cabinet door 101, install and debug the electrical components, ensure that all components are correctly connected and operate normally, and the upper surface of the second bracket 302 inside the base 3 is fixedly connected to the bottom of the heat sink 2, which ensures that the heat sink 2 is firmly supported. The first bracket 301, as the basic part of the base, is combined with the second bracket 302 to form a stable support structure. This design ensures that the control cabinet will not shake or tilt when placed or running, thereby protecting the internal electrical components from damage. The springs 303 are key components in the base 3. When external vibrations or shocks act on the control cabinet, these springs 303 can undergo elastic deformation to absorb and disperse these impact forces.

[0036] In the ventilation unit, after the air pump 401 is started, the external air is sucked into the bellows 4 through the air pump 401. The air is filtered by the second filter 405 in the bellows 4 to remove dust and impurities therein, ensuring that the air entering the cabinet 1 is clean. The filtered air is transported to the ventilation holes 701 of the bracket 7 through the ventilation duct 404. These ventilation holes 701 are evenly distributed on the front of the bracket 7, so that the air can flow evenly inside the cabinet 1 to achieve the purpose of heat dissipation. The heat dissipation unit quickly discharges the heat inside the cabinet 1 through the forced convection of the heat dissipation fan 6. At the same time, the design of the shutter 5 allows air flow, but can effectively prevent external impurities from entering the cabinet 1. The heat sink 8 further expands the heat dissipation area and improves the heat dissipation efficiency. When it is necessary to stop using, first turn off the air pump 401 and the heat dissipation fan 6, and then disconnect the power supply.
