Description

Technical Field

[0001] The present application relates to the technical field of electrical components, and in particular to an AC inductor box that is easy to dissipate heat. Background Art

[0002] The inductor is one of the important components of switching power supplies and power conversion equipment. The inductor is usually placed in an inductor box. The inductor box is responsible for placing the inductor, helping the inductor to dissipate heat, and enabling the inductor to work normally. Existing inductor boxes can usually be divided into two categories based on process materials: sheet metal splicing or aluminum die-casting.

[0003] The inductor will emit a lot of heat during use. If the inductor box cannot transfer this heat to the outside in time and control the ambient temperature around the inductor within a safe range, the stability of the power supply may be affected.

[0004] However, the existing inductor boxes have the following defects: the inductor box is generally a passive heat dissipation structure, and its heat dissipation speed is positively correlated with its own volume size. In order to obtain a better heat dissipation effect, it is usually necessary to design a larger appearance structure, which occupies more internal space of the equipment and is not conducive to installation and layout. Summary of the invention

[0005] One object of the present application is to provide an AC inductor box with compact structure and good heat dissipation effect and easy to dissipate heat.

[0006] To achieve the above objectives, the technical solution adopted in the present application is: an AC inductor box that is easy to dissipate heat, comprising a shell, a heat conducting plate is laid on the top of the shell, a plurality of heat dissipation fins are arranged on the top of the shell, the heat conducting plate passes through the plurality of heat dissipation fins, both ends of the heat dissipation fins extend to both sides of the shell, at least one heat dissipation pipe is arranged on both sides of the shell, the heat dissipation pipe passes through the plurality of heat dissipation fins, both ends of the heat dissipation pipe are connected to both ends of the heat conducting plate, and a heat conduction cycle is established.

[0007] In some embodiments, the heat conduction plate includes two heat conduction areas, and the heat conduction areas respectively establish a heat conduction cycle with the heat dissipation pipe on a side close to the shell.

[0008] In some embodiments, there are multiple heat dissipation pipes, and the heat dissipation pipes are distributed at equal intervals along the length direction of the shell.

[0009] In some embodiments, the heat dissipation pipes on the same side of the housing are connected to each other and are suitable for heat conduction.

[0010] In some embodiments, the length of the heat dissipation pipe close to the top of the housing is greater than the length of the heat dissipation pipe far from the top of the housing.

[0011] In some embodiments, a connecting edge is provided at the bottom of the shell, mounting columns connected to the connecting edge are provided on both sides of the shell, a mounting hole is opened on the connecting edge, and one end of the mounting hole is suitable for extending into the mounting column.

[0012] In some embodiments, both ends of the heat dissipation fin are connected to the connecting edge, and the width of the heat dissipation fin on both sides of the shell is not greater than the height of the mounting column protruding from the surface of the shell.

[0013] In some embodiments, at least one of the heat sink fins extends onto the mounting post.

[0014] In some embodiments, the diameter of the heat dissipation pipe is not greater than the width of the heat dissipation fins on both sides of the shell; the thickness of the heat conduction plate is not greater than the width of the heat dissipation fins on the top of the shell.

[0015] In some embodiments, the thickness of the heat conducting plate is smaller than the thickness of the heat dissipation pipe, and the width of the heat dissipation fins at the top of the housing is smaller than the width of the heat dissipation fins at both sides of the housing.

[0016] Compared with the prior art, the beneficial effect of the present application is that the easy-to-dissipate heat AC inductor box of the present application can help share the heat accumulated on the top of the shell to the two sides of the shell for heat dissipation by arranging heat dissipation pipes on both sides, thereby increasing the heat dissipation area, increasing the heat dissipation efficiency and heat dissipation capacity, and avoiding excessive local temperature of the shell. At the same time, due to the existence of the connecting edge of the shell, a certain amount of idle space will be generated on both sides of the shell. Arranging the heat dissipation pipes on both sides of the shell can make full use of the idle space on both sides of the shell, thereby reducing the height of the shell under the same heat dissipation efficiency, improving installation applicability, and facilitating layout.

[0022] Below, the present application is further described in conjunction with specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form new embodiments.

[0025] The terms "including" and "having" and any variations thereof in the specification and claims of this application are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0026] The present application is further described below with reference to the accompanying drawings:

[0027] like Figures 1 to 4 As shown, the present application provides an easy-to-dissipate heat AC inductor box, including a shell 1, a heat conducting plate 2 is laid on the top of the shell 1, a plurality of heat dissipation fins 3 are arranged on the top of the shell 1, the heat conducting plate 2 passes through the plurality of heat dissipation fins 3, both ends of the heat dissipation fins 3 extend to both sides of the shell 1, at least one heat dissipation pipe 4 is arranged on both sides of the shell 1, the heat dissipation pipe 4 passes through the plurality of heat dissipation fins 3, both ends of the heat dissipation pipe 4 are connected to both ends of the heat conducting plate 2, and a heat conduction cycle is established, and the heat conduction cycle means that the heat conducting plate 2 can continuously conduct heat to the heat dissipation pipe 4, and the heat dissipation pipe 4 dissipates the heat to the surrounding environment.

[0028] It is worth noting that the thermal conductivity cycle can be achieved not only by setting materials with different thermal conductivity coefficients for the heat conducting plate 2 and the heat pipe 4, but also by setting conventional heat dissipation structure technologies such as capillary heat dissipation structures in the existing technology inside the heat conducting plate 2 and the heat pipe 4.

[0029] The present application can transfer the heat on the top of the shell 1 to the two sides of the shell 1 by providing a heat conducting plate 2 and a heat dissipation pipe 4. The heat conducting plate 2 itself can increase the heat dissipation area on the top of the shell 1 to help the top of the shell 1 to dissipate heat. In addition, the heat conducting plate 2 can transfer the heat on the top of the shell 1 to each heat dissipation fin 3 more evenly, and can also transfer the heat on the top of the shell 1 to the heat dissipation pipe 4 on both sides of the shell 1. The heat dissipation pipe 4 itself can dissipate heat efficiently and can transfer the heat to the heat dissipation fin 3, thereby achieving uniform heat dissipation of the shell 1, avoiding the probability of local overheating, and improving the heat dissipation efficiency. Under the same volume, the inductor box can obtain higher heat dissipation efficiency by optimizing the heat dissipation structure.

[0030] In some embodiments, the heat conducting plate 2 , the housing 1 and the heat dissipating fins 3 are welded.

[0031] In some embodiments, the heat dissipation pipe 4 is welded to the heat dissipation fins 3 .

[0032] In some embodiments, the heat dissipation pipe 4 can be welded to the housing 1 and the heat dissipation fins 3 so that the heat dissipation pipe 4 can directly contact the housing 1 for heat conduction and can also contact the heat dissipation fins 3 for heat dissipation.

[0033] It is worth noting that Figures 1 to 4 The arrangement of the heat pipe 4 in the figure is only a preferred solution. In the actual design process, the shape, length, path and other details of the heat pipe 4 can be changed according to needs.

[0034] like Figure 2 In the illustrated embodiment, the heat conducting plate 2 includes two heat conducting areas 21 , which respectively establish a heat conducting cycle with the heat dissipating pipes 4 on one side close to the shell 1 , ensuring that the heat on the top of the shell 1 can be more evenly conducted to the heat dissipating pipes 4 on both sides of the shell 1 .

[0035] In some embodiments, two separate heat spreader structures in the prior art can be arranged inside the heat conducting plate 2 to form two heat conducting areas 21. The heat pipe 4 and the heat conducting plate 2 can be connected and conduct heat through a material with a high thermal conductivity coefficient. The heat spreader structure of the heat conducting area 21 can also be directly connected and combined with the heat dissipation structure inside the heat pipe 4 to facilitate direct heat dissipation circulation.

[0036] like Figure 3 In the illustrated embodiment, there are multiple heat dissipation tubes 4 , which are evenly spaced along the length direction of the shell 1 . Increasing the number of heat dissipation tubes 4 can directly improve the heat dissipation efficiency and more effectively utilize the space on both sides of the shell 1 .

[0037] like Figures 3 to 4In the illustrated embodiment, the heat dissipation tubes 4 on the same side of the housing 1 are interconnected and suitable for heat conduction, so that the multiple heat dissipation tubes 4 on the same side of the housing 1 can dissipate the heat load as evenly as possible to maximize the heat dissipation efficiency.

[0038] like Figures 3 to 4 In the embodiment shown, the length of the heat dissipation tube 4 close to the top of the shell 1 is greater than the length of the heat dissipation tube 4 far from the top of the shell 1. Since the heat conduction between the heat dissipation tubes 4 decreases step by step, the heat dissipation tube 4 far from the top of the shell 1 needs to dissipate less heat than the heat dissipation tube 4 close to the top of the shell 1. By shortening the length, the production cost can be reduced, the waste of materials can be reduced, and the weight of the shell 1 can also be reduced, thereby achieving an overall lightweight design.

[0039] like Figure 3 In the illustrated embodiment, a connecting edge 11 is provided at the bottom of the shell 1. The function of the connecting edge 11 is to help the shell 1 fit onto the surface of the device. Mounting posts 12 connected to the connecting edge 11 are provided on both sides of the shell 1. A mounting hole 13 is provided on the connecting edge 11. One end of the mounting hole 13 is suitable for extending into the mounting post 12. The connecting edge 11 can be fixed to the surface of the device through the mounting hole 13. Since the shell 1 itself is a thin structure, the mounting post 12 needs to be provided to ensure that the mounting hole 13 has sufficient structural strength, but this will also cause a certain waste of space on both sides of the shell 1.

[0040] like Figure 1 In the embodiment shown, both ends of the heat sink fin 3 are connected to the connecting edge 11, so that the coverage rate of the heat sink fin 3 on the shell 1 is improved as much as possible, thereby improving the heat dissipation efficiency. The width of the heat sink fin 3 on both sides of the shell 1 is not greater than the height of the mounting column 12 protruding from the surface of the shell 1. The heat sink fin 3 is hidden inside the mounting column 12, reducing the probability of structural interference of the heat sink fin 3 with the installation arrangement of the shell 1, thereby improving the installation applicability.

[0041] like Figure 1 In the illustrated embodiment, at least one heat sink fin 3 extends onto the mounting post 12 . In this case, the heat sink fin 3 can also play a role in structural reinforcement, thereby improving the structural stability of the heat sink fin 3 and the mounting post 12 .

[0042] like Figure 2 In the embodiment shown, the diameter of the heat pipe 4 is not greater than the width of the heat sink fins 3 on both sides of the shell 1, that is, the heat sink fins 3 can completely surround and contact the heat pipe 4, so that the heat at the heat pipe 4 can be most efficiently transferred to the heat sink fins 3. At the same time, the heat pipe 4 is hidden in the heat sink fins 3, which can reduce the probability of the heat pipe 4 causing structural interference with the installation arrangement of the shell 1.

[0043] like Figure 4In the illustrated embodiment, the thickness of the heat conducting plate 2 is not greater than the width of the heat dissipating fins 3 at the top of the housing 1 , and the heat conducting plate 2 is hidden in the heat dissipating fins 3 , which can reduce the probability of the heat conducting plate 2 causing structural interference to the installation arrangement of the housing 1 .

[0044] It is understandable that in order to reduce the height of the shell 1, it is necessary to reduce the space occupied at the top of the shell 1. Therefore, the width of the heat sink fins 3 at the top of the shell 1 is usually smaller than the width of the heat sink fins 3 on both sides of the shell 1. It can be concluded that the thickness of the heat conducting plate 2 is also usually smaller than the thickness of the heat pipe 4. The only way to ensure the heat dissipation efficiency and make the entire heat dissipation structure more compact is to set the heat conducting plate 2 structure on the top of the shell 1 and move the main heat dissipation structures such as the heat pipe 4 to both sides of the shell 1.

[0045] The compact structure of the inductor box of the present application is mainly achieved by utilizing the space in the longitudinal projection direction of the connecting line 11 on both sides of the shell 1, arranging the heat pipe 4 in the idle space, and conducting heat to the heat pipe 4 through the heat conducting plate 2 on the top of the shell 1, so that the heat pipe 4 can share the heat dissipation pressure on the top of the shell 1, thereby reducing the heat dissipation pressure on the top of the shell 1, and the heat dissipation fins 3 on the top of the shell 1 no longer need to increase the width to increase the surface area to obtain a stronger heat dissipation capacity, ultimately allowing the width of the heat dissipation fins 3 on the top of the shell 1 to be reduced.

[0046] The above describes the basic principles, main features and advantages of the present application. Those skilled in the art should understand that the present application is not limited by the above embodiments, and the above embodiments and the specification only describe the principles of the present application. The present application may have various changes and improvements without departing from the spirit and scope of the present application, and these changes and improvements fall within the scope of the present application for which protection is sought. The scope of protection claimed by the present application is defined by the attached claims and their equivalents.
