Description

Technical Field

[0001] This utility model relates to the field of heat dissipation technology for power distribution cabinets, specifically a top heat dissipation mechanism for outdoor power distribution cabinets. Background Technology

[0002] A distribution cabinet is a device that assembles switching equipment, measuring instruments, protective electrical devices, and auxiliary equipment in a closed or semi-closed metal cabinet according to electrical wiring requirements. Its layout should meet the requirements of normal operation of the power system, facilitating maintenance while ensuring the safety of personnel and surrounding equipment. In power distribution systems, distribution cabinets are typically used for centralized control of multiple devices, resulting in numerous electrical components and complex circuits inside. Prolonged use of multiple devices can lead to a heavy load on the distribution cabinet, causing significant heat generation from the internal electrical components and cables, resulting in excessively high internal temperatures. Therefore, heat dissipation measures are necessary for the distribution cabinet.

[0003] Traditional distribution cabinets have only one layer of sheet metal on top, resulting in poor heat dissipation. Under sunlight, the internal temperature of the distribution cabinet rises very quickly, which is not conducive to the heat dissipation of internal electrical components. Moreover, due to the thinness of the sheet metal, the load-bearing capacity of the top of the distribution cabinet is poor. In some hailstorms or when objects fall from heights, the top of the distribution cabinet is prone to deformation, affecting the normal use of internal electrical components. Utility Model Content

[0004] The purpose of this invention is to provide a top heat dissipation mechanism for outdoor power distribution cabinets to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A top heat dissipation mechanism for an outdoor power distribution cabinet includes a cabinet body. A heat dissipation shell is fixedly installed on the top of the cabinet body. The heat dissipation shell includes a top plate, a bottom plate, a first side plate, and a second side plate. Two first side plates and two second side plates are vertically fixedly connected between the top plate and the bottom plate. Adjacent first side plates and second side plates are perpendicular to each other and fixedly connected. A cavity is formed between the top plate, the bottom plate, the two first side plates, and the two second side plates. A circular through groove is provided on the surface of the bottom plate. Multiple heat dissipation slots are equidistantly provided on the surfaces of the two first side plates. The interior of the cabinet body is connected to the outside through the circular through groove, the cavity, and the heat dissipation slots.

[0007] Preferably, an auxiliary cooling fan is fixedly installed at the bottom of the base plate, the center of the auxiliary cooling fan coincides with the center of the circular through groove, and the fan blades of the auxiliary cooling fan extend into the interior of the circular through groove.

[0008] Preferably, the cavity is provided with an air guiding structure, which includes a first baffle and a second baffle. The first baffle is vertically fixedly connected to the inside of the cavity, and the two second baffles are vertically fixedly connected between the first baffle and the first side plate.

[0009] Preferably, the two air guiding structures are symmetrically arranged inside the cavity, and the sidewall of the first baffle is tangent to the top edge of the circular through groove.

[0010] Preferably, the first baffle and the second side plate are inclined to each other, the second baffle is inclined, and the first baffle, the second baffle and the second side plate form an isosceles trapezoidal structure.

[0011] Preferably, a reinforcing rod is vertically fixed between the two second side plates, and a receiving groove is provided on the surface of the first baffle, with the reinforcing rod engaging inside the receiving groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] This utility model features a heat dissipation shell on the top of the cabinet, with an internal cavity. The heat dissipation grooves on the side of the shell engage with the cavity, and an auxiliary cooling fan and air guide structure rapidly dissipate heat from the inside of the cabinet, ensuring effective heat dissipation.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a top heat dissipation mechanism for an outdoor power distribution cabinet, including a cabinet body 1. A heat dissipation shell 2 is fixedly installed on the top of the cabinet body 1. The heat dissipation shell 2 includes a top plate 3, a bottom plate 4, a first side plate 5, and a second side plate 6. The two first side plates 5 and the two second side plates are vertically fixedly connected between the top plate 3 and the bottom plate 4, and the two adjacent first side plates 5 and the two second side plates 6 are perpendicular to each other and fixedly connected. A cavity 7 is formed between the top plate 3, the bottom plate 4, the two first side plates 5, and the two second side plates 6. A circular through groove 8 is provided on the surface of the bottom plate 4. A plurality of heat dissipation grooves 9 are equidistantly provided on the surfaces of the two first side plates 5. The interior of the cabinet body 1 is connected to the outside through the circular through groove 8, the cavity 7, and the heat dissipation grooves 9.

[0022] Please see Figure 1 and Figure 4 In this embodiment, a heat dissipation shell 2 is provided on the top of the cabinet 1. The two first side plates 5 and the two second side plates 6 in the heat dissipation shell 2 are vertically fixed between the top plate 3 and the bottom plate 4. Therefore, for the heat dissipation shell 2 as a whole, the two first side plates 5 and the two second side plates 6 can support the top plate 3, thereby increasing the impact resistance and load-bearing capacity of the top of the cabinet 1. Moreover, for the heat dissipation shell 2, the heat dissipation groove 9 can assist the electrical components inside the shell to dissipate heat through the cavity 7 and the circular through groove 8, thereby ensuring the normal use of the electrical components.

[0023] An auxiliary cooling fan 10 is fixedly installed at the bottom of the base plate 4. The center of the auxiliary cooling fan 10 coincides with the center of the circular through groove 8, and the fan blades of the auxiliary cooling fan 10 extend into the interior of the circular through groove 8.

[0024] Please see Figure 2 and Figure 3The auxiliary cooling fan 10 is a conventional cooling fan in the prior art. After it is installed inside the circular through slot 8, it can realize the rapid exchange of air between the inside of the cabinet 1 and the cavity 7, thereby facilitating the heat dissipation of the electrical components inside the cabinet 1.

[0025] The cavity 7 is equipped with an air guiding structure, which includes a first baffle 11 and a second baffle 12. The first baffle 11 is vertically fixed inside the cavity 7, and the two second baffles 12 are vertically fixed between the first baffle 11 and the first side plate 5. The two air guiding structures are symmetrically arranged inside the cavity 7. The side wall of the first baffle 11 is tangent to the top edge of the circular through groove 8. The first baffle 11 and the second side plate 6 are inclined to each other. The second baffle 12 is inclined. The first baffle 11, the second baffle 12 and the second side plate 6 form an isosceles trapezoidal structure.

[0026] Please see Figure 3 and Figure 4 The larger side of the opening formed by the two inclined second baffles 12 faces the heat dissipation groove 9, while the smaller side faces the auxiliary cooling fan 10. Therefore, when the external airflow enters the cavity 7, it can enter between the two first baffles 11 along the inclined second baffles 12, thus facilitating the flow of air from between the two first baffles 11 into the circular through groove 8, thereby guiding the external airflow. Furthermore, the isosceles trapezoidal structure formed by the two second baffles 12, the first baffles 11, and the second side plate 6 can further increase the overall impact resistance and load-bearing capacity of the heat dissipation shell 2, thereby further increasing the mechanical strength of the top of the cabinet 1.

[0027] A reinforcing rod 13 is vertically fixed between the two second side plates 6. A receiving groove 14 is provided on the surface of the first baffle 11. The reinforcing rod 13 is engaged inside the receiving groove 14. There are three reinforcing rods 13. The three reinforcing rods 13 are equidistantly distributed inside the cavity 7, and the top surface of the three reinforcing rods 13 is in contact with the bottom of the top plate 3.

[0028] Please see Figure 3 and Figure 4 The reinforcing rod 13 can be installed at a vertical angle between the two first baffles 11 and the second side plate 6, thereby increasing the strength of the first baffles 11 and the first side plate 5 in the longitudinal direction, so as to further increase the mechanical strength of the top of the cabinet 1, so as to prevent the top of the cabinet 1 from deforming and affecting the normal use of the internal electrical components in the event of hail or falling objects from a height.

[0029] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
