[0002] Air-cooled transformers are transformers that manage heat through air cooling. Although the transformer can dissipate some heat through natural heat dissipation, under high load or high ambient temperature conditions, fans are often needed to accelerate the dissipation of transformer heat.

[0003] Traditionally, air-cooled transformer fans are secured to the transformer box using two bent angle irons, which serve as lateral support structures and are fixed to the back of the fan. However, due to the width of the angle irons, they partially block the fan's airflow path, preventing the airflow from reaching the transformer's heat sink completely and directly, thus reducing the transformer's cooling efficiency. Utility Model Content

[0004] The main purpose of the utility model is to provide a heat dissipation structure that increases the air output, realizes an unobstructed blowing path of the fan, increases the effective air output of the fan, and solves the problem that the current fan bracket structure blocks the fan outlet path, resulting in poor heat dissipation effect of the transformer.

[0005] Another object of the present invention is to provide a transformer using the above-mentioned heat dissipation structure with increased air output, thereby effectively improving the heat dissipation effect of the transformer and solving the problem of poor heat dissipation effect of the current transformer.

[0006] To achieve the above-mentioned object, the present invention proposes a heat dissipation structure for increasing air output, which is applied to a transformer. The heat dissipation structure includes a fan and a bracket. The fan includes an outer cylinder and a mounting frame. The mounting frame is arranged to protrude outward from the outer cylinder.

[0037] The utility model provides a heat dissipation structure for increasing the air output.

[0038] In the embodiment of the present utility model, Figure 1 、 Figure 2 and Figure 8 As shown, the heat dissipation structure for increasing air output is applied to a transformer. The heat dissipation structure includes a fan 1 and a bracket 2. The fan 1 includes an outer cylinder 11 and a mounting frame 12. The mounting frame 12 is arranged to protrude outward from the outer cylinder 11. The bracket 2 includes a first fixing component 21 and a second fixing component 22.

[0039] The first fixing assembly 21 includes a plurality of supporting members 211;

[0040] The second fixing assembly 22 includes a polygonal connection frame 221 and a plurality of fasteners 222. The polygonal connection frame 221 is vertically arranged. One end of the support member 211 is connected to the transformer body 3, and the other end of the support member 211 is connected to the polygonal connection frame 221.

[0041] The polygonal connecting frame 221 is provided with a plurality of first mounting holes 2211 along its thickness direction. A first ventilation cavity 2212 is defined in the middle of the polygonal connecting frame 221. The outer cylinder 11 is provided with a circular second ventilation cavity 111. The second ventilation cavity 111 is located inside the first ventilation cavity 2212.

[0042] The polygonal connecting frame 221 partially overlaps with the installation frame 12 , and the fasteners 222 are installed in the first installation holes 2211 to fix the installation frame 12 to the polygonal connecting frame 221 .

[0043] The present invention connects the polygonal connection frame 221 to the transformer body 3 through the support member 211 of the first fixing assembly 21. The installation frame 12 of the fan 1 partially overlaps with the polygonal connection frame 221. At the overlapping position, the installation frame 12 is fixed to the polygonal connection frame 221 by fasteners 222. The second ventilation cavity 111 of the outer cylinder 11 is located inside the first ventilation cavity 2212 of the polygonal connection frame 221. The polygonal connection frame 221 does not block the air outlet of the fan 1, thereby achieving an unobstructed air blowing path of the fan 1, increasing the effective air output of the fan 1, and allowing the air blown out by the fan 1 to act completely and directly on the transformer body 3, further improving the heat dissipation effect of the transformer. This solves the problem that the current fan 1 support structure blocks the fan 1 air outlet path, resulting in poor heat dissipation effect of the transformer.

[0044] Preferably, the plurality of first mounting holes 2211 are symmetrically arranged. The symmetrical arrangement of the first mounting holes 2211 can enhance the connection strength between the fastener 222 and the polygonal connecting frame 221 and the mounting frame 12, thereby improving the stability and reliability of each connection position.

[0045] like Figures 4 to 6 As shown, in one embodiment of the present application, the polygonal connection frame 221 is ring-shaped, and the shapes of the outer edge and the inner edge of the polygonal connection frame 221 are both regular hexagons.

[0046] The shape of the outer edge and the shape of the inner edge of the polygonal connection frame 221 are both regular hexagons. At this time, the polygonal connection frame 221 presents a regular and beautiful structure; in actual production and manufacturing, the polygonal connection frame 221 is easier to process than the circular frame. Therefore, the use of the polygonal connection frame 221 in the present invention is conducive to simplifying the production process and realizing large-scale production.

[0047] Preferably, the support member 211 is an angle iron.

[0048] Preferably, the polygonal connection frame 221 is composed of multiple angle irons. The angle iron frame used as the polygonal connection frame 221 can improve the overall structural stability and effectively support the weight of the fan 1 and oscillations during operation. Preferably, the thickness of the polygonal connection frame 221 is 8 mm.

[0049] like Figure 1 As shown, in one embodiment of the present application, the inner edge of the polygonal connection frame 221 is tangent to the edge of the second ventilation cavity 111 .

[0050] When the inner edge of the polygonal connection frame 221 is tangent to the edge of the second ventilation cavity 111, it will not block the blowing path of the fan 1, thereby increasing the air output of the fan 1. The tangent design can improve the aesthetics of the device.

[0051] like Figure 4 As shown, in one embodiment of the present application, the first mounting hole 2211 is a waist-shaped hole, and the first mounting hole 2211 is arranged between the outer edge of the polygonal connecting frame 221 and the inner edge of the polygonal connecting frame 221 .

[0052] The first mounting hole 2211 is a waist-shaped hole. The first mounting hole 2211 is set between the outer edge and the inner edge of the polygonal connecting frame 221. Compared with ordinary circular mounting holes, the waist-shaped hole has greater flexibility. When the fastener 222 passes through the first mounting hole 2211, there can be a larger tolerance space. No precise alignment is required, which facilitates the passage of the fastener 222, and can significantly improve the installation efficiency and success rate of the fastener 222.

[0053] like Figure 5 As shown, in one embodiment of the present application, the first mounting hole 2211 is a U-shaped hole, and the first mounting hole 2211 is provided with an opening 2211 a , and the direction of the opening 2211 a is vertically arranged upward.

[0054] In order to further improve the connection efficiency between the polygonal connecting frame 221 and the mounting frame 12 of the fan 1, the first mounting hole 2211 is set as a U-shaped hole, and its opening 2211a is perpendicular to the ground and upward. During installation, one end of the fastener 222 passes through the mounting frame 12 of the fan 1, and then can slide into the U-shaped hole from the opening 2211a of the U-shaped hole. In this way, the fastener 222 can be installed without the first mounting hole 2211 corresponding to the corresponding position of the mounting frame 12. Therefore, the connection efficiency between the polygonal connecting frame 221 and the mounting frame 12 of the fan 1 can be further improved.

[0055] like Figures 1 to 6 As shown, in one embodiment of the present application, a plurality of support members 211 are arranged at intervals along the vertical direction.

[0056] Several support members 211 are arranged at intervals along the vertical direction. Reasonable intervals can ensure that the load borne by the support members 211 can be evenly distributed to the connection points, avoiding local stress concentration, thereby improving the stability of the overall structure.

[0057] like Figure 4 As shown, in one embodiment of the present application, a plurality of support members 211 are connected to the same side of the polygonal connection frame 221; or, as shown in FIG. Figure 6 As shown, a plurality of support members 211 are connected to two adjacent sides of the polygonal connection frame 221 .

[0058] Whether the plurality of support members 211 are connected to the same side of the polygonal connection frame 221 or to two adjacent sides, the polygonal connection frame 221 can be prevented from being deformed when subjected to the gravity of the fan 1 , thereby improving the load-bearing capacity of the present invention.

[0059] like Figures 4 to 6 As shown, in one embodiment of the present application, the width of the support member 211 is greater than the difference between the radii of the circumscribed circle and the inscribed circle of the polygonal connection frame 221 .

[0060] The width of the support member 211 is greater than the difference between the radii of the circumscribed circle of the outer edge and the inscribed circle of the inner edge of the polygonal connecting frame 221. When the width of the support member 211 is sufficient, it has sufficient bending rigidity and can more effectively provide support for the polygonal connecting frame 221, thereby helping to improve the overall rigidity of the polygonal connecting frame 221. In this way, when the second fixing component 22 is connected to the fan 1, the bracket 2 can maintain good shape and position stability.

[0061] like Figures 1 to 3 、 Figure 7 As shown, in one embodiment of the present application, the mounting frame 12 is provided with a plurality of second mounting holes 121 , and the first mounting holes 2211 are provided in a one-to-one correspondence with the second mounting holes 121 ;

[0062] The fastener 222 includes a bolt 2221 and a nut 2222 . The bolt 2221 passes through the first mounting hole 2211 and the second mounting hole 121 and is threadedly connected to the nut 2222 .

[0063] The mounting frame 12 of the fan 1 is provided with a second mounting hole 121 corresponding one-to-one to the first mounting hole 2211. The fastener 222 passes through the first mounting hole 2211 and the second mounting hole 121 in sequence and is connected to the nut 2222, so that the fan 1 can be fixed on the bracket 2; the size of the first mounting hole 2211 is larger than the size of the second mounting hole 121, or the size of the first mounting hole 2211 is consistent with the size of the second mounting hole 121; when the size of the first mounting hole 2211 is larger than the size of the second mounting hole 121, the position of the fastener 222 can be adjusted more easily during installation, thereby adjusting the installation position of the heat dissipation structure.

[0064] Using bolts 2221 and nuts 2222 as fasteners 222 can generate sufficient friction to make the connection between the second fixing component 22 and the fan 1 more firm and reliable, forming a structure with higher overall strength, and effectively preventing failures or accidents caused by loose connection between the fan 1 and the bracket 2; in addition, when the fan 1 operates abnormally, the bolts 2221 and nuts 2222 can be removed for maintenance to replace the fan 1, which reduces maintenance time, improves maintenance efficiency, and better meets actual application needs.

[0065] The present invention also proposes a transformer using the above heat dissipation structure for increasing air flow, such as Figure 8 As shown, the transformer includes a transformer body 3 and the above-mentioned heat dissipation structure for increasing air output.

[0066] The heat dissipation structure for increasing the air output is fixedly set on the transformer, which can maximize the air output of the fan 1, effectively improve the heat dissipation effect of the transformer, and solve the problem of poor heat dissipation effect of the current transformer.

[0067] The technical principles of the present invention have been described above with reference to specific embodiments. These descriptions are intended solely to illustrate the principles of the present invention and should not be construed in any way as limiting the scope of protection of the present invention. Based on the explanations herein, those skilled in the art will be able to devise other specific implementations of the present invention without inventive effort, and such implementations will fall within the scope of protection of the present invention.
