However, the heat dissipation fin design of the transformer is relatively simple, and is arranged in parallel in a straight line.

DETAILED DESCRIPTION

[0024] like Figures 1 to 5 and 7 to 8:

[0025] A transformer comprises a transformer body 101, wherein a top seat 103 and a base 102 are fixedly connected to the upper and lower ends of the transformer body 101, respectively, and two shells 201 are symmetrically slidably connected between the base 102 and the top seat 103, and heat sinks are installed at the outer ends of the two shells 201; and the front and rear sides of the transformer body 101 can be rotatably connected to a plurality of heat dissipation fins 302;

[0026] When the two shells 201 slide apart and open, the transformer body 101 is exposed for heat dissipation. When encountering typhoon weather, the two shells 201 are controlled to move closer to each other to a buckled state, so as to cover the transformer body 101 for protection, thereby preventing the transformer body 101 from being hit by foreign objects blown up in the air and being damaged when a typhoon occurs;

[0027] Furthermore, when the transformer body 101 needs to dissipate heat quickly, the two shells 201 are opened, and the transformer body 101 can dissipate heat quickly after being exposed. At the same time, the two shells 201 can drive the multiple heat dissipation fins 302 located on both sides to rotate outward, so that the multiple heat dissipation fins 302 are in a divergent form from the middle to the two sides. Compared with the traditional multiple heat dissipation fins 302 that are parallel to each other, the multiple heat dissipation fins 302 are divergently dispersed, so that the spacing between the multiple heat dissipation fins 302 becomes larger, which can dissipate heat more quickly, promote the exchange of heat with the surrounding air, effectively improve the heat dissipation performance, and facilitate the heat transfer of the transformer body 101 to the outside through the multiple heat dissipation fins 302, thereby improving the heat dissipation efficiency of the transformer body 101.

[0028] like Figure 3 , 4 , 6, 12 to 13 as shown:

[0029] Two crosses 104 are symmetrically fixed between the base 102 and the top base 103. Two transverse grooves 203 are symmetrically provided on the opposite surfaces of the two shells 201. The two ends of the two crosses 104 are respectively inserted into the four transverse grooves 203.

[0030] Two side frames 106 are fixedly connected symmetrically between the base 102 and the top seat 103. Vertical grooves 202 are provided on the outer end surfaces of the two shells 201. The two side frames 106 are respectively inserted into the two vertical grooves 202.

[0031] When the two shells 201 are opened, the two crosses 104 are located at the front and rear sides of the transformer body 101 to play a blocking and protective role, and the two side frames 106 are located at the left and right sides of the transformer body 101 to play a blocking and protective role. Figure 3 and 4As shown, the two crosses 104 and the two side frames 106 can prevent garbage such as plastic bags floating in the air from adhering to the transformer body 101 and affecting the heat dissipation of the transformer body 101. At the same time, they also prevent birds from entering the space formed by the transformer body 101 and the two shells 201 and affecting the normal operation of the transformer body 101.

[0032] like Figures 7 to 9 As shown:

[0033] The heat sink comprises a fan frame 204 fixedly connected to the outer end surface of the housing 201, a fan 205 is rotatably connected inside the fan frame 204, and a motor 206 for driving the fan 205 to rotate is fixedly connected to the fan frame 204;

[0034] When the two shells 201 are opened, the two motors 206 are controlled to start and drive the two fans 205 to rotate. When the two fans 205 are running, the hot air near the transformer body 101 can be drawn out through the vertical slots 202, thereby improving the fluidity of the air near the transformer body 101. The increased air fluidity can take away the heat of the transformer body 101 itself more quickly, thereby improving the heat dissipation efficiency of the transformer body 101 itself.

[0035] like Fig. 9 As shown:

[0036] The inner sides of the two side frames 106 are fixedly connected with a storage seat 107 for storing the motor 206;

[0037] When the two shells 201 are closed together, the cross 104 blocks the horizontal slot 203, the side frame 106 blocks the vertical slot 202, and the motor 206 is stored in the corresponding storage seat 107. The setting of the storage seat 107 avoids interference between the motor 206 and the side frame 106, which causes the side frame 106 to be unable to be embedded in the vertical slot 202.

[0038] like Figure 6 , 12 As shown in 13:

[0039] Two electric push rods 105 are symmetrically fixed to the two crosses 104, and the telescopic ends of the four electric push rods 105 are respectively fixed to the two sides of the two housings 201;

[0040] The electric push rods 105 on both sides are activated to drive the two housings 201 to move closer to each other or move away from each other to open.

[0041] like Fig.10 As shown:

[0042] The front and rear sides of the transformer body 101 are symmetrically fixed with a plurality of hinged frames 301, each hinged frame 301 is rotatably connected with a rotating shaft 303, and a plurality of heat dissipation fins 302 are respectively fixed on the plurality of rotating shafts 303;

[0043] The rotating shaft 303 can rotate on the hinge frame 301, thereby driving the heat dissipation fins 302 to rotate, thereby changing the angle of the heat dissipation fins 302, so that the multiple heat dissipation fins 302 present a radial divergent shape, thereby promoting the exchange of heat with the surrounding air and effectively improving the heat dissipation performance.

[0044] like Figure 4 , 8 , 10 to 11:

[0045] A gear 304 is fixedly connected to the lower end of each rotating shaft 303, and two racks 207 are symmetrically fixedly connected to the inner walls of the two housings 201, and the four racks 207 are respectively meshed and transmission-connected with the multiple gears 304 on the corresponding side;

[0046] When the two shells 201 move outward and open, the racks 207 thereon are synchronously driven to move outward, and the multiple racks 207 drive the multiple gears 304 to rotate by meshing with the corresponding multiple gears 304, and the multiple gears 304 drive the multiple heat dissipation fins 302 to rotate outward, thereby changing the inclination angle of the heat dissipation fins 302;

[0047] Furthermore, when the rack 207 moves outward, it disengages from the gear 304 from the inside to the outside, so the rotation amplitude of the multiple heat dissipation fins 302 connected to each rack 207 increases from the inside to the outside, so that the multiple heat dissipation fins 302 on both sides present a divergent shape, such as Figure 4 As shown, efficient heat dissipation is facilitated.

[0048] like Fig.10 As shown:

[0049] A rubber plug is provided at the rotation connection between the rotating shaft 303 and the articulated frame 301 ; the rubber plug can increase the rotational friction between the rotating shaft 303 and the articulated frame 301 , so that the heat dissipating fins 302 can be automatically fixed in angle after being rotated to any position.

[0050] like Figure 2 As shown:

[0051] The lower end of the base 102 is symmetrically fixed to two cross beams; screw holes are provided on the cross beams for inserting screws to fix the transformer body 101 on a designated pole frame.
