[0002] A distribution cabinet is a general term for a motor control center. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits, and motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit of the upper-level distribution equipment to the nearest load. This level of equipment should provide protection, monitoring and control for the load. When the distribution cabinet is working, the electrical components inside it will release heat. Common distribution cabinets cannot quickly discharge the heat from the distribution cabinet, and the heat will gather upward in the cabinet. Without the assistance of external force, the heat can only be dissipated slowly, and when the back of the distribution cabinet is in contact with the wall, the back of the distribution cabinet cannot dissipate heat normally, thereby further reducing its heat dissipation effect. For this reason, the present application proposes an electrical equipment distribution box. Utility Model Content

DETAILED DESCRIPTION
[0019] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments; based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.
[0020] Depend on Figure 1-6The utility model comprises a cabinet 1, a base 2 and supporting legs 3. A storage slot is provided on the top of the base 2. The bottom of the cabinet 1 is located in the storage slot on the top of the base 2. Two left-right symmetrical air inlets 4 are provided at the bottom of the cabinet 1. A first cooling fan 5 is fixedly installed at the bottom ends of the two air inlets 4. A plurality of guide plates 6 are fixedly installed in the two air inlets 4 and above the first cooling fan 5. The plurality of guide plates 6 in each air inlet 4 are neatly arranged in a diffuse shape on both sides. Under the action of the guide plates 6, the first cooling fan 5 blows out The wind can be evenly diverted into the cabinet 1, so that the wind blown by the first cooling fan 5 can quickly send the heat in the cabinet 1 to the top thereof, and then cooperate with the two second cooling fans 11 to discharge the heat from the cabinet 1. Two through openings 7 are provided at the bottom of the base 2, and the two through openings 7 are respectively located below the two air inlets 4. The tops of both sides of the cabinet 1 are provided with air outlets 10 connected with the interior thereof, and two second cooling fans 11 are fixedly installed in each air outlet 10. The side of the cabinet 1 is provided with a heat dissipation groove 13 that runs through its back plate.
[0021] At the same time, the two through ports 7 are both threadedly connected with a threaded ring 8, and the first dustproof net 9 is fixedly installed in the two threaded rings 8. The size of the through port 7 is larger than the size of the bottom opening of the air inlet 4. The first dustproof net 9 in the threaded ring 8 can prevent the first cooling fan 5 in the air inlet 4 from dust, and can also prevent dust from entering the cabinet 1 through the through port 7 and the air inlet 4.
