Description

Technical Field

[0001] The invention relates to the technical field of oil-immersed transformers, and in particular to an air-conducting oil-immersed transformer with double heat dissipation. Background Art

[0002] Oil-immersed transformers are one of the important equipment in the power supply and distribution systems of industrial and mining enterprises and civil buildings. Their heat dissipation efficiency has a significant impact on the working performance and safe operation of the transformer.

[0003] At present, when dissipating heat, oil-immersed transformers generally use the method of installing heat dissipation fins on the sides of the oil-immersed transformer to dissipate heat. This heat dissipation method has high requirements on the temperature of the external environment. The traditional oil-immersed transformer conducts heat to the heat dissipation fins through the body, and only dissipates heat through the heat dissipation fins. The heat dissipation speed is slow, thereby increasing the heat loss of the transformer core, which is not conducive to the normal and good operation of the oil-immersed transformer. Therefore, it is necessary to provide an oil-immersed transformer that can dissipate heat efficiently to solve the above technical problems. Summary of the invention

[0004] In order to solve the above technical problems, the present invention provides a double heat dissipation wind-conducting oil-immersed transformer, comprising a base, a transformer box, a copper tube heat dissipation mechanism, a fin heat dissipation mechanism, a fan mechanism, an air guide plate, and a temperature sensor control mechanism;

[0005] The transformer box is installed on the base;

[0006] The copper tube heat dissipation mechanism is composed of a plurality of long copper tubes and a plurality of short copper tubes, wherein the long copper tubes and the short copper tubes are hollow and are welded on both sides of the transformer box, and the transformer oil in the transformer box can flow into the short copper tubes;

[0007] The fin heat dissipation mechanism is composed of a plurality of heat dissipation fins, the heat dissipation fins are penetrated by the long copper tube, the heat dissipation fins are equidistantly arranged outside the four sides of the transformer box, the heat dissipation fins are in direct contact with the long copper tube but not connected; the heat dissipation fins are directly welded to the transformer box;

[0008] The fan mechanism is composed of a plurality of fans and a fan base, the fans are fixed on the fan base, the fan base is fixed directly above the fin heat dissipation mechanism, and the operating state of the fan mechanism is controlled by the temperature sensor control mechanism;

[0009] The air guide plate is welded to the lower right end of the heat dissipation fin;

[0010] The temperature sensing control mechanism is composed of a temperature sensor and a controller, and is installed on the top outer side of the transformer box.

[0011] Preferably, the fan in the fan mechanism delivers wind downward, and the generated wind passes through each of the heat dissipation fins from top to bottom.

[0012] Preferably, the fan surface in the fan mechanism is covered by a dustproof mesh cover.

[0013] Preferably, a semiconductor cooling fin is installed on the surface of the heat dissipation fin, and a circular hole is drilled on the surface of the heat dissipation fin.

[0014] Preferably, the air guide plate is in a 1 / 4 arc shape, the upper end of the air guide plate is tangent to the long side of the heat dissipation fin, and the lower end of the air guide plate is tangent to the short side of the heat dissipation fin.

[0015] Compared with the prior art, the present invention provides a wind-conducting oil-immersed transformer with dual heat dissipation, which has the following beneficial effects:

[0016] 1. The double heat dissipation wind-conducting oil-immersed transformer adds a copper tube heat dissipation mechanism with high thermal conductivity. The transformer oil in the transformer is double-cooled through the copper tube heat dissipation mechanism and the fin heat dissipation mechanism, which can effectively improve the heat dissipation efficiency of the transformer;

[0017] 2. The left outer surface of each fin of the fin heat dissipation mechanism in the double heat dissipation wind-guiding oil-immersed transformer is equipped with a semiconductor cooling plate, which speeds up the heat dissipation of the transformer oil and reduces the dependence on the external ambient temperature of the transformer. In addition, a 1 / 4 arc-shaped air guide plate is installed at the lower end of the right side of each fin of the fin heat dissipation mechanism. The air guide plate can prevent the backflow of the wind blown out by the fan mechanism at the upper end of the heat dissipation fin, greatly improving the heat dissipation efficiency and effectively reducing the heat loss of the transformer;

[0018] 3. The fan mechanism of the double heat dissipation wind-conducting oil-immersed transformer is controlled by a temperature sensor control mechanism. The fan mechanism will only start working when the temperature is greater than the set threshold, effectively reducing energy loss. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The transformer box 2 is installed on the base 1;

[0031] The copper tube heat dissipation mechanism 3 is composed of a plurality of long copper tubes 301 and a plurality of short copper tubes 302. The long copper tubes 301 and the short copper tubes 302 are hollow and are welded at both ends around the transformer box 2. The transformer oil in the transformer box 2 can flow into the long copper tubes 301.

[0032] The fin heat dissipation mechanism 4 is composed of a plurality of heat dissipation fins 401, the heat dissipation fins are penetrated by the long copper tube 301, the heat dissipation fins are equidistantly arranged on the outside of the transformer box 2, the heat dissipation fins 401 are in direct contact with the long copper tube 301, but not connected; the heat dissipation fins 401 are directly welded to the transformer box 2;

[0033] The fan mechanism 5 is composed of a plurality of fans 501 and a fan base 502, wherein the fans 501 are fixed on the fan base 502, and the fan base 502 is fixed directly above the fin heat dissipation mechanism 4, and the operating state of the fan mechanism 5 is controlled by the temperature sensing control mechanism 7;

[0034] The air guide plate 6 is welded to the lower right end of the heat dissipation fin 401;

[0035] The temperature sensing control mechanism 7 is composed of a temperature sensor 701 and a controller 702 , and is installed on the top outer side of the transformer box 2 .

[0036] Specifically, the long copper tube 301 is connected to the short copper tube 302 via a 90° copper tube elbow 303 .

[0037] In this embodiment, the long copper tube 301 and the short copper tube 302 are connected by using a 90° copper tube elbow 303, which can effectively solve the problem of difficult assembly and is more convenient for disassembly and replacement.

[0038] Specifically, the fan 501 in the fan mechanism 5 delivers wind downward, and the generated wind passes through each of the heat dissipation fins 401 from top to bottom.

[0039] In this embodiment, the fan 501 in the fan mechanism 5 is fixed directly above the fin heat dissipation mechanism 4 through the fan base 502. When the temperature value detected by the temperature sensor 701 is greater than the set value, the controller 702 controls the fan 501 to start working and blow air towards the heat dissipation fins 401, so that the generated wind passes through each heat dissipation fin 401 from top to bottom, thereby taking away the heat of the heat dissipation fins 401.

[0040] Specifically, the surface of the fan 501 in the fan mechanism 5 is covered by a dustproof mesh cover 503 .

[0041] In this embodiment, the dustproof mesh cover 503 can not only effectively prevent foreign mosquitoes from flying into the fan 501 to prevent damage to the fan 501 and ensure the blowing effect of the fan 501, but also protect personnel safety to prevent fingers or tools from reaching into the fan 501.

[0042] Specifically, a semiconductor cooling fin 402 is installed on the surface of the heat dissipation fin 401 , and a round hole 403 is drilled on the surface of the heat dissipation fin 401 .

[0043] In this embodiment, the semiconductor cooling sheet 402 is installed on the surface of the heat dissipation fin 401 to achieve the purpose of cooling the heat dissipation fin 401. In combination with the wind source delivered by the fan 501, the heat dissipation efficiency can be greatly improved and the heat loss of the transformer can be reduced. Circular holes 403 are evenly drilled from top to bottom on the surface of the heat dissipation fin 401, and the long tube 301 is passed through the circular holes 403 and penetrates the heat dissipation fin 401.

[0044] Specifically, the air guide plate 6 is a 1 / 4 arc-shaped metal plate, the upper end of the air guide plate 6 is tangent to the long side of the heat dissipation fin 401 , and the lower end of the air guide plate is tangent to the short side of the heat dissipation fin 401 .

The fan mechanism 5 delivers wind source to each heat dissipation fin 401, absorbs heat on the surface of the heat dissipation fin 401 to form a heat flow, and the heat flow flows from top to bottom to the air guide plate 6, and then takes the heat flow away through the 1 / 4 arc of the air guide plate 6, which can effectively reduce the backflow of the heat flow, thereby improving the heat dissipation efficiency and reducing the heat loss of the transformer.

[0046] The present invention and its embodiments are described schematically above, which is not restrictive.
