Description

Technical Field

[0001] The present application relates to the technical field of power distribution cabinets, and more specifically, to a power distribution box for electrical engineering. Background Art

[0002] The distribution box is an important part of the electrical system, used to distribute, control and protect electrical energy. It usually contains switchgear, measuring instruments, protective electrical appliances and auxiliary equipment, etc. These devices are assembled in a closed or semi-closed metal cabinet or on a screen to form a low-voltage distribution box.

With the continuous growth of electricity demand and the continuous development of electrical technology, the application field of distribution boxes is also constantly expanding. Since the internal electronic components of the distribution cabinet will generate high temperature during operation, heat will accumulate inside, which is easy to cause spontaneous combustion.

[0003] In order to solve the above problems, the present application provides a distribution box for electrical engineering. Summary of the invention

[0010] In summary, this application includes the following beneficial technical effects:

[0011] The heat dissipation mechanism not only realizes natural convection through the air inlet grille and the air outlet grille, but also introduces the air inlet motor and the cooling fan for active heat dissipation. This combination greatly improves the heat dissipation efficiency and ensures that the temperature inside the distribution box is always kept within the appropriate range.

[0021] The present application embodiment discloses a distribution box for electrical engineering. Figure 1-Figure 4 , including a power distribution cabinet housing 1, a door body 5 is provided on one side of the power distribution cabinet housing 1, an air inlet grille 4 is penetrated at the bottom of the power distribution cabinet housing 1 located on the adjacent side of the door body 5, an air outlet grille 2 is penetrated at the top of the power distribution cabinet housing 1 located on the adjacent side, and mutually symmetrical exhaust motors 3 are penetrated at the top of the power distribution cabinet housing 1, longitudinal and mutually symmetrical support columns 6 are provided between the inner walls of the power distribution cabinet housing 1, and transverse reinforcing ribs 7 are provided between the power distribution cabinet housing 1 and the support columns 6. A heat dissipation mechanism 8 is provided between the support columns 6 at the bottom of the inner side of the power distribution cabinet housing 1, and the support columns 6 and the reinforcing ribs 7 are cross-stacked and distributed, and the support columns 6 and the reinforcing ribs 7 are fixedly connected by bolts, and a heat dissipation fan is provided in the exhaust motor 3. The door body 5 is cleverly configured on one side of the power distribution cabinet housing 1 for easy maintenance and repair. At the bottom of the adjacent side of the door body 5, air inlet grilles 4 are evenly penetrated to effectively introduce external cold air. At the top of the adjacent side, an air outlet grille 2 is provided to ensure that hot air is discharged smoothly, forming natural convection and improving heat dissipation efficiency. In order to further enhance the heat dissipation effect, mutually symmetrical exhaust motors 3 are also installed on the top of the power distribution cabinet housing 1. Each exhaust motor is integrated with a heat dissipation fan. Through active exhaust, the internal hot air is accelerated to be discharged, ensuring that the electrical components operate at a suitable temperature and extending the service life. Longitudinal and mutually symmetrical support columns 6 are set between the two sides of the power distribution cabinet housing 1. These support columns not only provide stable support, but also optimize the internal space layout. At the same time, transverse reinforcing ribs 7 are added between the power distribution cabinet housing 1 and the support columns 6, and between the support columns 6. These reinforcing ribs and the support columns are cross-stacked and distributed, and are tightly fixed and connected by bolts, which greatly enhances the overall structural strength and anti-deformation ability of the distribution box. At the bottom of the distribution box, located between the support columns 6, a heat dissipation mechanism 8 is also carefully designed. This mechanism can further assist in heat dissipation and ensure that the temperature inside the distribution box is uniform and kept within a safe range.

[0022] The heat dissipation mechanism 8 includes a mounting frame 801, the top of the mounting frame 801 is provided with mutually symmetrical protective grilles 802, the bottom of the mounting frame 801 is penetrated with mutually symmetrical air inlet motors 803, the inner walls of the mounting frame 801 are provided with mutually symmetrical cross mounting frames 804, and the output end of the air inlet motor 803 is penetrated by one end of the cross mounting frame 804 and is provided with a heat dissipation fan 805, the mounting frame 801 is a ladder-shaped mechanism, the air inlet motor 803 is fixed in the power distribution cabinet housing 1 through the mounting frame 801, and the core component of the heat dissipation mechanism 8 is a ladder-shaped mounting frame 801, which not only optimizes the space utilization, but also enhances the stability of the overall structure. At the top of the mounting frame 801, there are mutually symmetrical protective grilles 802, which can not only effectively prevent external debris from entering the heat dissipation mechanism, but also prevent fingers or other objects from accidentally touching the heat dissipation fan to a certain extent, thereby improving the safety of use, and the bottom of the mounting frame 801 is penetrated with mutually symmetrical air inlet motors 803, which are the power source of the heat dissipation mechanism. They generate strong suction by rotating at high speed, and introduce external cold air into the distribution box. In order to ensure that the cold air can be evenly distributed and effectively take away the heat, a cross mounting frame 804 is passed through the output end of each air inlet motor 803, and a cooling fan 805 is installed on it. Driven by the air inlet motor, these cooling fans accelerate the air flow and form strong air convection, thereby greatly improving the heat dissipation efficiency. The entire heat dissipation mechanism 8 is firmly fixed inside the distribution cabinet housing 1 through the mounting frame 801. This integrated design not only simplifies the installation process, but also ensures the close fit between the heat dissipation mechanism and other components of the distribution box, further improving the overall heat dissipation performance.

[0023] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
