Description

Technical Field

[0001] The utility model relates to the technical field of transformers, in particular to a transformer cooling device. 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, and it cannot meet the cooling effect of the heat generated by the transformer during operation. As a result, the temperature of the transformer will continue to rise during continuous operation, which will lead to a reduction in its service life and an increase in the damage rate of internal components.
