[0002] The professional name of the transformer on the market is "control transformer", "isolation transformer", "single-phase transformer", "EI transformer", etc. The main function of the transformer is to change the power supply voltage through electromagnetic induction. The main structure of such a transformer is composed of a core, a coil winding, a terminal / wire, and a mounting base.

[0003] Since the internal power elements of the transformer are constantly working when the transformer is running, the transformer generates a lot of heat. In order to prevent temperature rise from causing operation failure or shutdown accident, a heat dissipation hole is generally provided on the outer cover of the transformer. However, such a heat dissipation hole needs to rely on the natural wind outside to dissipate heat. When the transformer is in a hot summer and windless environment, the heat of the transformer itself is difficult to actively discharge, which can easily cause the transformer to be damaged due to high temperature, thereby affecting the service life of the transformer.
