Description

Technical Field

[0001] This utility model relates to a dual-airflow circulating heat dissipation distribution box. Background Technology

[0002] As a core supporting equipment of electrical systems, distribution boxes are widely used in many fields such as industrial production, construction engineering, and power transmission. They integrate a large number of precision electrical components, which continuously generate heat during operation.

[0003] Existing distribution boxes mostly adopt a single-channel heat dissipation design, which dissipates heat through only a single heat dissipation channel or a single-sided heat dissipation component. Moreover, the heat dissipation coverage is limited, and it is impossible to achieve all-round heat exchange for electrical components, which can easily lead to local heat accumulation and affect the normal operation of components. In view of this, this utility model proposes a dual-channel circulating heat dissipation distribution box to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to provide a dual-airflow circulating heat dissipation power distribution box to solve the problems mentioned in the background art.

The partitions are connected to the top of the box. A heat dissipation cavity is provided between the partitions and the side panels. The box is equipped with two sets of heat dissipation components, which are matched with the two sets of heat dissipation cavities, so that flowing air enters the heat dissipation cavity to complete the heat dissipation process.

[0006] As an improvement to the above technical solution, an air outlet groove is provided on the partition plate, and the air outlet groove is located near the top of the box.

[0007] As an improvement to the above technical solution, a sealing plate is provided between the two sets of partitions, and the sealing plate divides the box into a first cavity and a second cavity; The first cavity is used to house electrical components, and the second cavity is used to house heat dissipation components.

[0008] As an improvement to the above technical solution, the heat dissipation component includes a heat dissipation connecting plate, which is connected to a sealing plate and a side plate. The heat dissipation connecting plate has multiple sets of heat dissipation through holes and multiple sets of cooling fans, with the positions of the multiple sets of cooling fans matching those of the multiple sets of heat dissipation through holes.

[0011] As an improvement to the above technical solution, a fixing plate is also provided on the box body. The fixing plate is connected to the box body by bolts and is located in the second cavity.

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Example: like Figure 1-10 As shown, this embodiment proposes a dual-airflow circulating heat dissipation power distribution box, including a box body 10, the box body 10 is provided with a box top 11, and two sets of side plates 13 are symmetrically arranged on the box body 10. Two sets of partitions 30 are symmetrically arranged inside the housing 10. The two sets of partitions 30 are matched with the two sets of side plates 13. The partitions 30 are connected to the top 11 of the housing. A heat dissipation cavity 40 is arranged between the partitions 30 and the side plates 13. Two sets of heat dissipation components 50 are arranged inside the housing 10. The two sets of heat dissipation components 50 are matched with the two sets of heat dissipation cavities 40, so that flowing air enters the heat dissipation cavity 40 to complete the heat dissipation process.

[0016] In this embodiment, when heat dissipation is performed inside the housing 10, electrical components are installed in the inner cavity of the housing 10 and placed between the two sets of heat dissipation cavities 40. Then, the two sets of heat dissipation components 50 respectively introduce fluid air into the two sets of heat dissipation cavities 40. The flowing air carries away the heat generated by the housing 10, thereby completing the dual-channel heat dissipation process of the housing 10. The dual-channel heat dissipation structure, which uses two sets of symmetrically arranged heat dissipation cavities 40 and heat dissipation components 50, allows air to be simultaneously introduced into the heat dissipation cavity 40 from both sides of the electrical component, forming a bidirectional heat dissipation path, effectively improving the heat dissipation coverage and efficiency, and avoiding local heat accumulation in the electrical component. The fitting connection and symmetrical layout of the partition 30 with the side plate 13 and the top of the box 11 not only ensures the structural stability of the heat dissipation cavity 40, but also places the electrical components in the core heat dissipation area between the two sets of heat dissipation cavities 40, ensuring that heat can be quickly conducted and discharged through the flowing air, significantly improving the heat exchange effect inside the distribution box. Meanwhile, the symmetrical structural design ensures uniform airflow distribution, reduces heat dissipation dead zones, lowers the risk of electrical component failure due to localized overheating, optimizes the utilization rate of the internal space of the distribution box, provides coordinated support for the assembly of electrical components and the operation of the heat dissipation system, and improves the overall reliability and service life of the distribution box.

[0017] Specifically, the partition 30 is provided with an air outlet groove 14, which is located near the top of the box 11.

[0018] In this embodiment, the air outlet duct 14 is located near the top of the box 11 on the partition 30. It can adapt to the physical characteristics of hot air rising naturally, so that the hot air generated by heat dissipation inside the heat dissipation cavity 40 can quickly gather and be discharged from the air outlet duct 14 at the top of the box 11 along the natural convection direction, effectively shortening the residence path of hot air in the heat dissipation cavity 40 and improving the efficiency of hot air discharge.

[0019] Specifically, a sealing plate 20 is provided between the two sets of partitions 30, and the sealing plate 20 divides the box 10 into a first cavity 21 and a second cavity 22; The first cavity 21 is used to place electrical components, and the second cavity 22 is used to place the heat dissipation assembly 50.

[0020] In this embodiment, the housing 10 is clearly divided into a first cavity 21 and a second cavity 22 by the sealing plate 20, so that the electrical components and the heat dissipation assembly 50 are respectively in independent cavities. This effectively prevents airflow disturbances, mechanical vibrations or external impurities such as dust and water vapor generated when the heat dissipation assembly 50 is working from entering the area where the electrical components are located through the heat dissipation channel, thereby reducing the risk of short circuits, poor contact and other faults caused by external interference to the electrical components and improving the stability and safety of the operation of the electrical components. The second cavity 22 serves as a dedicated installation space for the heat dissipation component 50, allowing the assembly, debugging, and subsequent maintenance of the heat dissipation component 50 to be completed within an independent cavity without disassembling or touching the electrical components in the first cavity 21. This significantly reduces the risk of misoperation of electrical components during the maintenance of the heat dissipation system and improves the overall maintenance efficiency and convenience of the distribution box. At the same time, the independent second cavity 22 avoids the mutual encroachment of space between the heat dissipation component 50 and electrical components, providing ample space for the specification selection and layout optimization of the heat dissipation component 50, and ensuring the full utilization of heat dissipation performance.

[0021] Specifically, the heat dissipation component 50 includes a heat dissipation connecting plate 51, which is connected to the sealing plate 20 and the side plate 13. The heat dissipation connecting plate 51 has multiple sets of heat dissipation through holes 53 and multiple sets of heat dissipation fans 52, with the positions of the multiple sets of heat dissipation fans 52 matching the positions of the multiple sets of heat dissipation through holes 53.

[0022] In this embodiment, the connection design of the heat dissipation connecting plate 51 with the sealing plate 20 and the side plate 13 can, on the one hand, stably assemble the heat dissipation component 50 in the second cavity 22 of the box 10, avoid displacement of the heat dissipation component 50 due to vibration, airflow impact, etc. during operation, and ensure the stability of the heat dissipation system operation; on the other hand, the heat dissipation connecting plate 51 can serve as a structural support component inside the second cavity 22, enhance the integrity and deformation resistance of the internal structure of the box 10, and improve the overall structural strength of the distribution box. The matching design of multiple cooling fans 52 and multiple cooling holes 53 allows the airflow generated by the cooling fans 52 to enter the heat dissipation cavity 40 accurately and directionally through the cooling holes 53, avoiding disordered diffusion or turbulence of airflow in the second cavity 22, minimizing airflow loss, ensuring that the cooling airflow can act efficiently on the heat exchange area of ​​the heat dissipation cavity 40, and improving the utilization efficiency of the cooling airflow.

[0023] Specifically, the heat dissipation through hole 53 is provided with heat dissipation mounting holes 54 around it, and the cooling fan 52 is provided with fan mounting holes 521. The fan mounting holes 521 and heat dissipation mounting holes 54 are matched in position, and the fan mounting holes 521 and heat dissipation mounting holes 54 are connected by bolts.

[0024] Specifically, the partition 30 is provided with multiple sets of heat-conducting fins 31, and the multiple sets of heat-conducting fins 31 are evenly arranged on the partition 30.

[0025] In this embodiment, by setting multiple sets of heat-conducting fins 31 on the partition 30, the contact area between the partition 30 and the airflow inside the heat dissipation cavity 40 can be effectively increased, enhancing the ability of the partition 30 to absorb and conduct heat generated when the electrical components are working. Compared with the flat partition 30 without fins, the design of multiple sets of fins can significantly improve the heat transfer rate from the partition 30 to the flowing air, providing a more sufficient heat exchange basis for the subsequent airflow to carry away the heat, and further optimizing the heat dissipation efficiency.

[0026] Specifically, a fixing plate 12 is also provided on the box body 10. The fixing plate 12 is connected to the box body 10 by bolts, and the fixing plate 12 is located at the second cavity 22. An air inlet slot 121 is provided on the fixed plate 12.

[0027] In this embodiment, the fixing plate 12 is detachably connected to the housing 10 by bolts and is set corresponding to the second cavity 22. When the heat dissipation component 50 needs to be inspected or replaced in the future, the fixing plate 12 can be removed by simply removing the bolts, without disassembling the main body of the housing 10 or disturbing the structure of the first cavity 21, which significantly reduces the maintenance difficulty of the heat dissipation system and improves maintenance efficiency. The air inlet slot 121 on the fixed plate 12 can serve as the dedicated air inlet path for the second cavity 22, enabling directional guidance of external airflow. This allows outside air to precisely enter the interior of the second cavity 22 along the air inlet slot 121 and flow towards the heat dissipation component 50, preventing disorderly diffusion of airflow outside the housing 10 or entry from non-preset paths. This ensures that the heat dissipation component 50 always receives a sufficient and stable airflow supply, providing front-end protection for the airflow circulation of the dual-channel heat dissipation structure.

[0028] 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.
