Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer heat dissipation structure. Background Art

[0002] A transformer is a device that uses the principle of electromagnetic induction to change AC voltage. Its main components are the primary coil, the secondary coil, and the iron core. When a high-power transformer is in use, the internal coil current is large, which generates a lot of heat during the operation of the transformer. If the heat dissipation capacity of the transformer is too low, the transformer temperature is likely to be too high, which can easily cause the transformer to be damaged.

[0003] When the transformer is in use, it is necessary to dissipate the heat generated during its operation. The existing heat dissipation methods mostly rely on heat dissipation fins to transfer heat. When this method is used, first of all, the heat transfer efficiency is low. At the same time, the heat dissipation method is too single, resulting in the temperature of the heat dissipation fins constantly rising during the heat dissipation process, which in turn leads to an increase in its heat dissipation temperature and cannot reduce the transformer problem. As a result, heat accumulates inside the transformer, resulting in problems such as efficiency and use being affected. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes a transformer heat dissipation structure.

[0007] Preferably, the driving mechanism comprises a plurality of circumferentially arranged blades fixedly connected to the side wall of the rotating shaft, and the blades are arranged at both ends of the rotating shaft.

[0008] Preferably, the auxiliary mechanism comprises a plurality of circumferentially arranged swing plates fixedly connected to the side wall of the rotating shaft, and the swing plates are arranged between two of the extension plates.

[0009] Preferably, a heat dissipation groove is provided on one side of the extension plate.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] 1. The utility model is provided with a storage box, a heat dissipation fin, an extension plate, a heat dissipation slot and other structures. By arranging the heat dissipation fins in the storage box and extending them outward through the extension plate, the heat dissipation fins and the side walls of the transformer are contacted and dissipated by the rainwater stored in the storage box while the heat dissipation fins are used for heat dissipation. This can improve the heat dissipation efficiency of the transformer and avoid the problem of heat being unable to be dissipated due to a single heat dissipation method of the transformer.

[0014] 2. The utility model is provided with structures such as a rotating shaft, fan blades and a swinging plate. The wind energy flowing out of the transformer drives the fan blades to drive the rotation of the rotating shaft. The rotation and swinging of the swinging plate can increase the air flow rate at the storage box and the extension plate, accelerate the transfer of heat in the air, and thus achieve the effect of improving the heat dissipation efficiency of the transformer.
