Novel forced directional air-cooling system

The utility model relates to a novel forced directional air-cooling system, and belongs to the technical field of ground-buried box-type transformer station cooling equipment for power. The system consists of an axial-flow centrifugal fan and an oil-immersed transformer. The system is characterized in that a channel is disposed between a lamp box and a ground-buried transformer box; an air inlet of the axial-flow centrifugal fan lifted on a partitioning plate at the bottom of the lamp box is close to a lateral shutter sealing plate; the upper part of the ground-buried transformer box is provided with a cover plate, and the front part of the ground-buried transformer box is provided with a vertical shutter sealing plate; a cooling fin of the oil-immersed transformer disposed in the ground-buried transformer box is provided with an air-flue directional air mouth through an air-flue directional bent plate; the air-flue directional air mouth is connected with the axial-flow centrifugal fan through a dedicated air flue for an blower fan; and an air outlet of the axial-flow centrifugal fan is perpendicular to the air-flue directional air mouth. The system achieves circulating ventilation, is good in heat dissipation performance, is low in fault rate of a transformer, is long in service life, is low in maintenance cost, and solves the problems that a conventional ground-buried transformer station has frequent faults caused by the poor circulating ventilation and heat dissipation performance, is short in service life, and is high in maintenance cost.
