the oil guide device comprises two fixed pipes which are arranged at intervals, wherein a sealed oil guide cavity is formed in each fixed pipe; the axial direction of the fixed pipe extends left and right; the left inner side and the right inner side of each of the two fixed pipes are correspondingly communicated and fixed with an oil outlet and an oil return port which are arranged on the left corresponding side and the right corresponding side of a transformer oil tank respectively;

the hollow spiral plate is fixedly wound on the fixed pipe, and two ends of the hollow spiral plate are opened;

the radial oil guide blocks are correspondingly fixed on the two fixed pipes and arranged along the radial direction of the fixed pipes, oil guide channels are arranged in the radial oil guide blocks, and one ends of the oil guide channels facing the radial inner side are communicated to the oil guide cavities of the fixed pipes; the oil guide cavity is communicated with one end, close to the transformer oil tank, of the corresponding hollow spiral plate;

and the two ends of the transition hollow plate are fixedly communicated to one ends of the two hollow spiral plates far away from the transformer oil tank in a one-to-one correspondence manner.

Preferably, the two hollow spiral plates are arranged to be staggered in the left-right direction.

Preferably, the fixed tube is internally fixed with a plug and the plug is positioned at the near end part of one end of the left inner side and the right inner side of the fixed tube; and an opening is formed in one end, far away from the transformer oil tank, of the fixing pipe.

The utility model discloses a novel transformer heat dissipation device, it sets up the hollow spiral plate on fixed pipe through fixed dispels the heat in to the air, and the hollow core slab intercommunication of transition is passed through to the outer end of two sets of hollow spiral plates to form a endless heat dissipation channel. Because the radial inner side contour line of the hollow spiral plate is shorter, the welding workload between the hollow spiral plate and the fixed pipe is smaller, and the hollow spiral plate is easy to manufacture; and the hollow spiral plate is of an integrated structure, and the structural strength is much higher than that of a plurality of spaced corrugated plates in the prior art, so that the hollow spiral plate is not reinforced by a support rod.
