Under the action of the air deflector 71, the wind blown by the heat dissipation fan blade 554 can be blown to the heat dissipation holes on the heat conduction plate 556 under the guidance of the air deflector 71, so that the air flow between the heat dissipation circulating oil pipe 53 and the heat conduction plate 556 is increased. The intelligent heat dissipation transformer can adjust the oil flow speed, distribute the flow, and cooperate with air cooling in the smart grid, so as to realize the overall temperature optimization.
