Cooling fin is fixed on outer wall, which is characterized in that the lower radiating surface of the cooling fin lower end is greater than the upper of cooling fin upper end
Radiating surface.
Since upper radiating surface is small compared with lower radiating surface, following radiating surface heat dissipation faster, fuel tank is connect with lower radiating surface
Position can also radiate comparatively fast, and the radiating rate above and below the vegetable insulating oil in such fuel tank is different and forms potential energy difference, promote to plant
The flowing of object insulating oil improves heat dissipation effect.Upper radiating surface and lower radiating surface situation in the same size in compared with the prior art,
Can cut down vegetable insulating oil viscosity it is larger caused by adverse effect.
Preferably, the area ratio of the upper radiating surface and the lower radiating surface is 0.66-0.85.Under normal conditions, fuel tank
Capacity is bigger, and ratio can be smaller.
Preferably, the cooling fin is corrugated plate.
Preferably, the cooling fin is in up-narrow and down-wide ladder-like.
Preferably, the cooling fin is in up-narrow and down-wide right-angled trapezium shape, and the outer edge of cooling fin is bevel edge.
Preferably, the outer edge of the upper radiating surface is in a vertical shape, and the outer edge of the lower radiating surface is outside from top to bottom
Inclination.
Preferably, the outer edge of the upper radiating surface is inclined outwardly from top to bottom, and the outer edge of the lower radiating surface is in perpendicular
Straight shape.
Preferably, when the vegetable insulating oil oil weight 128kg, the fin height be 500mm, upper radiating surface and it is lower dissipate
The area ratio in hot face is 0.79.
Preferably, when the vegetable insulating oil oil weight 192kg, the fin height be 600mm, upper radiating surface and it is lower dissipate

Specific embodiment
Just attached drawing in conjunction with the embodiments below, is described in further detail specific embodiment of the present utility model, so that this
Utility model technical solution is more readily understood, grasps.It should be appreciated that specific embodiment described herein is only to explain this reality
With novel, it is not used to limit the utility model.
Present embodiments provide for a kind of vegetable insulating oil transformer radiator structures, as shown in Figs 1-4, including fuel tank 100,
