[0038] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by technicians in the technical field to which this application belongs; the terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned figure descriptions are intended to cover non-exclusive inclusions.

[0039] Reference to "embodiments" herein means that a particular feature, structure, or characteristic described in conjunction with the embodiments may be included in at least one embodiment of the present application. The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0040] The following is combined with Figure 1-5 This application is described in further detail.

[0041] The embodiment of the present application discloses a European transformer outer box.

[0042] Reference Figure 1 The outer box of the European transformer includes a box body 1 and a top cover. The box body 1 is arranged in a rectangular box body 1 shape. The box body 1 is hollow and has an upper end opening. The top cover is installed at the upper end of the box body 1 to shield the box body 1.

[0043] Reference Figure 2 and Figure 3 Specifically, the top cover includes a mounting frame 2, four heat sinks 3 and a cover body 4. The mounting frame 2 is fixedly connected to the top of the box body 1. The four heat sinks 3 are fixedly connected to the upper side of the mounting frame 2. The four heat sinks 3 are arranged at intervals along the circumference of the mounting frame 2 to enclose a rectangular frame. The heat sinks 3 are provided with a plurality of penetrating heat dissipation holes 31. The plurality of heat dissipation holes 31 are evenly spaced along the length direction of the heat sink 3 and the length direction of each heat dissipation hole 31 is arranged along the vertical direction. The cover body 4 is arranged on the upper side of the four heat sinks 3. The circumference of the cover body 4 shields the heat dissipation holes 31 on the four heat sinks 3 to prevent rainwater from directly entering the heat dissipation holes 31. A heat dissipation channel 5 is formed between the circumference of the cover body 4 and the mounting frame 2.

[0044] In actual application, the top cover is installed on the top of the box body 1 by using the mounting frame 2, so that the interior of the box body 1 is connected with the interior of the top cover, and the heat emitted by each electrical device in the box body 1 is discharged from the mounting frame 2 to the four heat sinks 3, and the heat is discharged from each heat dissipation hole 31 to the heat dissipation channel 5 formed between the cover body 4 and the mounting frame 2, so as to ensure the heat dissipation effect of the box body 1. At the same time, the cover body 4 blocks rainwater, so that rainwater cannot directly enter the box body 1 from the heat dissipation hole 31, and it is difficult for rainwater to enter the heat dissipation hole 31 from bottom to top through the heat dissipation channel 5, and rainwater is prevented from entering between the four heat sinks 3 as much as possible, so as to prevent rainwater from entering the box body 1 as much as possible. Therefore, it is possible to ensure the heat dissipation effect of the box body 1 while preventing rainwater from entering the box body 1 as much as possible, thereby ensuring the normal operation of the electrical devices in the box body 1.

[0045] Reference Figure 4 In some embodiments, a plurality of rain shields 32 are fixedly connected to the inner side of the heat sink 3 at intervals along its length direction. The number of the rain shields 32 corresponds to the number of the heat dissipation holes 31, and the two ends of the rain shields 32 are respectively fixedly connected to the two ends of the heat dissipation holes 31 to shield the heat dissipation holes 31, thereby blocking rainwater and reducing the amount of rainwater entering the heat dissipation holes 31, thereby further preventing rainwater from entering the box body 1.

[0046] In some embodiments, the inner side of the heat sink 3 is bent to form a connecting piece 33, which is arranged in an "L"-shaped sheet and abuts against the upper side of the mounting frame 2 to increase the installation area between the heat sink 3 and the mounting frame 2, thereby improving the stability of the installation of the heat sink 3. At the same time, the connecting piece 33 has a certain height away from the side of the heat sink 3, which can also block some rainwater and increase the structural strength of the heat sink 3.

[0047] Reference Figure 5 In some embodiments, the lower side of the cover body 4 is bent to form a rain shield frame 41, which is arranged along the circumference of the cover body 4 and located in the heat dissipation channel 5. The rain shield frame 41 can further block rainwater to reduce rainwater from entering the heat dissipation channel 5, thereby further preventing rainwater from entering the box body 1.

[0048] In some embodiments, the cross-section of the rain shield frame 41 is in an "L" shape, so that a guide channel 42 is formed between the rain shield frame 41 and the cover body 4. Some rainwater entering from the heat dissipation channel 5 can be collected in the guide channel 42, and the rain shield frame 41 is provided with overflow grooves 43 at each corner. The guide channel 42 guides the rainwater to the overflow groove 43 for discharge, so that the rainwater can be discharged in time.

[0049] Reference Figure 3In some embodiments, the upper side of the cover 4 is arranged in a "human" shape to guide rainwater and avoid rainwater accumulation on the upper side of the cover 4. It should be noted that the shapes of the two heat dissipation plates 3 are changed according to the shape of the cover 4.

[0050] In some embodiments, the cover body 4 is detachably connected to the four heat sinks 3, so that the cover body 4 can be disassembled separately, so as to facilitate cleaning and maintenance of the heat dissipation holes 31 of the heat sink 3, and cleaning and maintenance of the guide channel 42 of the cover body 4, so as to ensure normal heat dissipation and normal drainage. It should be noted that in this embodiment, the cover body 4 is detachably connected to the four heat sinks 3 by bolts, and in other embodiments, the detachable connection of the cover body 4 can also be achieved by means of snap-on, plug-in, etc., which is not limited in this application.

[0051] In some embodiments, the top cover further includes two reinforcing sheets 6 , which are fixedly connected between two opposite heat sinks 3 at intervals to improve the connection strength between the four heat sinks 3 , thereby effectively improving the support strength of the cover body 4 .

[0052] In some embodiments, the upper side of each reinforcing sheet 6 abuts against the cover body 4 to support the cover body 4, increasing the supporting area of ​​the four heat sinks 3 and the cover body 4, further improving the supporting strength of the cover body 4, and allowing the cover body 4 to be installed more stably.

[0053] The implementation principle of this embodiment is as follows: the top cover is installed on the top of the box body 1 using the mounting frame 2, so that the interior of the box body 1 is connected to the interior of the top cover, and the heat emitted by each electrical device in the box body 1 is discharged from the mounting frame 2 to the four heat sinks 3, and the heat is discharged from each heat dissipation hole 31 to the heat dissipation channel 5 formed between the cover body 4 and the mounting frame 2, so as to ensure the heat dissipation effect of the box body 1. At the same time, the cover body 4 blocks rainwater, so that rainwater cannot directly enter the box body 1 from the heat dissipation hole 31, and it is difficult for rainwater to enter the heat dissipation hole 31 from bottom to top through the heat dissipation channel 5, and rainwater is prevented from entering between the four heat sinks 3 as much as possible, so as to prevent rainwater from entering the box body 1 as much as possible. Therefore, it is possible to ensure the heat dissipation effect of the box body 1 while preventing rainwater from entering the box body 1 as much as possible, thereby ensuring the normal operation of the electrical devices in the box body 1.

[0054] 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.
