[0032] Specifically, the return plate 201 is in a right-angle trapezoidal structure, and the inclined surface of the return plate 201 is arranged close to the transformer body 1. The utility model increases the contact area between the return plate 201 and the natural wind by arranging the return plate 201 in a right-angle trapezoidal structure and arranging the inclined surface of the return plate 201 close to the transformer body 1, so that more natural wind can be refluxed.

The utility model sets the drainage portion 2021 in an inclined structure, sets the high end of the drainage portion 2021 away from the transformer body 1, and sets the low end of the drainage portion 2021 close to the transformer body 1, so as to facilitate the natural wind to be guided into the reflux portion 2022, and sets the reflux portion 2022 in an arc-shaped structure, so that the natural wind will blow to the leeward side of the transformer body 1 after returning through the reflux portion 2022.

[0034] Furthermore, the fixing mechanism 3 includes a plug-in component 4 and a reinforcement component 5 ; wherein the reinforcement component 5 is arranged on the plug-in component 4 .

[0035] It is worth noting that the plug-in assembly 4 includes a fixing groove 401 and a fixing block 402; two fixing grooves 401 are symmetrically provided on the side of the return plate 201 close to the mounting frame of the transformer body 1; the fixing block 402 is arranged in the fixing groove 401, and the end of the fixing block 402 passes through the fixing groove 401 and is fixedly connected to the mounting frame of the transformer body 1; wherein the fixing block 402 is plugged in with the fixing groove 401. The utility model provides the return plate 201 with a disassembly function by providing the fixing groove 401 and the fixing block 402, and utilizing the plugging and matching of the fixing block 402 with the fixing groove 401, so that the return plate 201 can not only be replaced, but also the transformer body 1 and the return plate 201 can be conveniently disassembled for transportation, thereby improving the practicality of the utility model.

[0036] It is worth noting that the reinforcement component 5 includes a receiving groove 501, a connecting piece 502, a reinforcement block 503 and a reinforcement groove 504; two receiving grooves 501 are symmetrically provided on both sides of the fixed block 402; the connecting piece 502 is fixed in the receiving groove 501; wherein, the height dimension of the connecting piece 502 is smaller than the height dimension of the receiving groove 501; the reinforcement block 503 is fixed on the side of the connecting piece 502 away from the receiving groove 501; two reinforcement grooves 504 are symmetrically provided on both sides of the inner wall of the fixed groove 401; wherein, the reinforcement block 503 is snap-fitted with the reinforcement groove 504; wherein, the reinforcement block 503 is an isosceles triangle structure, and the inclined surface of the reinforcement block 503 is arranged along the vertical direction; when the end face of the fixed block 402 contacts the inner wall of the fixed groove 401, the fixed block 402 is plugged into the fixed groove 401, and the connecting piece 502 returns to its original shape. The utility model sets a receiving groove 501, a connecting piece 502, a reinforcing block 503 and a reinforcing groove 504, and utilizes the snap-fitting of the reinforcing block 503 and the reinforcing groove 504 and the elastic deformation of the connecting piece 502, so that the position of the fixing block 402 in the fixing groove 401 can be fixed, thereby preventing the return plate 201 from shaking when it contacts with natural wind, thereby affecting the utilization rate of natural wind.

[0037] Working principle: When the transformer body 1 is in use, the natural wind will first blow toward the windward surface of the transformer body 1 and the inclined surface of the return plate 201. The natural wind blowing to the inclined surface of the return plate 201 will flow into the return portion 2022 along the drainage portion 2021. After returning through the return portion 2022, the returned natural wind will blow toward the leeward side of the transformer body 1, so that the natural wind can take away the heat generated by the transformer body 1 to the greatest extent, thereby reducing the energy consumption of the transformer body 1. In addition, the natural wind will return through multiple return slots 202, so that the natural wind will stay near the transformer body 1 for a longer time, thereby improving the utilization rate of the natural wind.

[0038] When the return plate 201 needs to be disassembled, the return plate 201 is moved upward to make the fixing block 402 slide in the fixing groove 401, so that the inner wall of the reinforcement groove 504 squeezes the inclined surface of the reinforcement block 503, so that the connecting piece 502 is tilted and deformed in the receiving groove 501 until the end of the reinforcement block 503 contacts the inner wall of the fixing groove 401. At this time, the connecting piece 502 no longer tilts and deforms until the fixing block 402 is separated from the fixing groove 401. At this time, the end of the reinforcement block 503 no longer contacts the inner wall of the fixing groove 401, and the connecting piece 502 is no longer subjected to force and begins to tilt and deform in the opposite direction in the receiving groove 501 until the connecting piece 502 returns to its original shape. At this time, the disassembly of the return plate 201 is completed;

[0039] When the return plate 201 needs to be installed, the fixing block 402 is inserted into the fixing groove 401, so that the end of the fixing groove 401 squeezes the inclined surface of the reinforcement block 503, so that the connecting piece 502 is tilted and deformed in the receiving groove 501 until the end of the reinforcement block 503 contacts the inner wall of the fixing groove 401. At this time, the connecting piece 502 no longer tilts and deforms. When the end of the reinforcement block 503 contacts the inner wall of the reinforcement groove 504, the connecting piece 502 is no longer subjected to force and begins to tilt and deform in the opposite direction in the receiving groove 501 until the fixing block 402 is plugged into the fixing groove 401. At this time, the connecting piece 502 returns to its original shape, and the end face of the fixing block 402 contacts the inner wall of the fixing groove 401, and the installation of the return plate 201 is completed.
