JBF Transformer Axial Flow Fan Oil Transformer Air Cooled Cooling Fanworking principle

Its working principle is based on the heat dissipation principle of "forced oil circulation air cooling", which is an indirect cooling process:

1. Internal oil circulationThe heat generated during the operation of the transformer is first absorbed by the internal insulation oil. After being heated, the oil density decreases and naturally flows upwards, entering the radiator tube cluster outside the transformer.

2. External air coolingThe cooling fan is installed below or on the side of the radiator. When the fan is started, it generates a strong airflow that blows vertically or horizontally over the surface of the radiator's heat dissipation pipes.

3. heat exchangeEfficient heat exchange occurs between the airflow and the surface of the heat dissipation tube, quickly removing the heat from the high-temperature insulation oil in the tube.

4. circulating coolingAfter being cooled, the temperature of the oil decreases, the density increases, it naturally sinks, flows back to the bottom of the transformer oil tank, absorbs heat again, and forms a closed cooling circuit with natural circulation (or assisted by an oil pump for forced circulation).

In this way, the fan greatly enhances the heat dissipation capacity of the radiator, allowing the transformer to withstand greater loads.
