Refering to fig. 1 to Fig. 4, embodiment provides a kind of fuel tank corrugate fin group 101, including：A kind of fuel tank ripple is scattered
Backing group, including：The corrugate fin 100 of multiple parallel arrangements, multiple corrugate fins 100 are by plank successively bent
At, and the plank is formed simultaneously fuel tank sidewall after repeatedly bending in one end of multiple corrugate fins 100 of formation
106；The both ends of each corrugate fin 100, which are connected with, pushes section 102, and each pushing section 102 is far from the ripple
One end of groups of fins 101 is connected with lengthening section 103.
In the present embodiment, each corrugate fin 100 is the flat light wall pipe of 1.5-2cm thickness, and shape is flat close to cuboid
Three bandings in addition to nozzle of pipe corrugate fin 100 close, vertical extension 1m, lateral length 20cm, corrugate fin 100
Shape is vertical high, and thickness is thin, and only there are one openings in vertical cross-section, and the height being open and 100 height one of corrugate fin
It causes, opening thickness and 100 consistency of thickness of corrugate fin.The vertical stylolite of each corrugate fin 100 is circular arc, circular arc half
Diameter is 1cm, and the vertical stylolite of corrugate fin 100 can also be to have not having even for certain radian in other embodiments certainly
It is cambered.Air line distance between each corrugate fin 100 is 5 centimetres.Each corrugate fin 100 is by steel plate bending
It gets, bending mode is carried out according to following operation：For corrugate fin 100 with 0.2-0.5cm thickness, 5 meters long, width is 1.3m former
Material, line 90-degree bent centered on 5cm on the length direction of sheet metal goes out by sheet metal width direction, then in the longitudinal direction
Negative direction bends 180 ° on the direction of distance center line 20cm, and wherein this goes out bending segment bending thickness 2cm, that is, forms 1cm
The circular arc of radius is bent, and makes the distance of shape 2cm between two sections of sheet metals of bending place.The then 45cm on sheet metal length direction
On start to re-start above-mentioned operation, successively cycle go down to be formed each thickness be 2cm, vertical height and lateral length one
The corrugate fin 100 of cause.Certainly the corrugate fin group 101 of the present invention can also pass through time processing in other embodiments
Molding obtains, and forming method is not stated tired here.
Each 100 vertical upper and lower ends of corrugate fin, which are both provided with, pushes section 102.Push section 102 there are purposes to be
The lateral cross opening for closing 100 upper and lower ends of corrugate fin, since corrugate fin 100 is made of sheet metal, has
Certain intensity, the thickness of each corrugate fin 100 in 2cm, between weld difficult realize.Therefore it is dissipated by bending each ripple
The left and right two panels sheet metal of 100 upper and lower ends of backing connects or close to center line, will be on corrugate fin 100 by continuously welding
Lower both ends suture, but the length bent avoids the waste of steel plate raw material, while the corrugate fin bent no more than 10mm

It is completely enclosed to the bending of the one end at center, but between making 100 both ends of each corrugate fin or so different sheet metal away from
From for 0.5cm, while 102 extension of section is pushed to 25-30mm, extended part forms lengthening section 103, lengthening section 103
One end far from 100 vertical center of corrugate fin passes through continuous welded seal.
One end of each opening of the lengthening section 103 far from corrugate fin 100 is provided with reinforcing bar 104, reinforcing bar 104
Purpose is avoided in fuel tank in use in order to avoid 100 insufficient strength of corrugate fin formed by sheet metal is big
Oil, which thermally expands impact, causes corrugate fin 100 to deform twice bended, therefore the intensity of reinforcing bar 104 wants sufficiently large, therefore adds
Gu bar 104 is the solid iron of 1-2cm diameters.Each of 100 both ends of corrugate fin are respectively welded at by two irons to add
The sharp corner that long section 103 is open far from corrugate fin 100, though make corrugate fin 100 in corrugate fin group 101 by
It also can guarantee and do not bend to larger oil shock.
Simultaneously because entire corrugate fin group 101 is formed using same sheet metal bending process, thus it is thin bending
While steel plate forms corrugate fin 100, the laterally spaced steel plates of 5cm between each corrugate fin are also formed, simultaneously also
There is the corrugate fin 100 of 2cm to be open, it is each to be spaced due to forming spacer 105 when bending corrugate fin 100
105 all in the same plane, the width 5cm of spacer 105, highly highly consistent with the sheet metal that uses is 1.3m to section, therefore
Multiple spacers 105 and the oil outlet 108 of corrugate fin group 101 constitute fuel tank sidewall 106, it is noted that fuel tank
Side wall 106 in a lateral direction, the distance apart from corrugate fin opening be 5-10mm this segment distance preferably there are, while in order to
Sheet metal raw material is saved, the pressurized segment vertical extension of the composition fuel tank sidewall 106 of upper end can be set as 0-20mm in vertical direction,
But in order to the lengthening section 103 for equally reaching top be also when being welded with fuel tank upper cover 110 continuously weld, therefore preferably
103 length of lengthening section of upper end is 10-20mm in ground vertical direction.
Corrugate fin finally forms fuel tank side due to being provided with opening, opening in vertical cross-section with spacer 105
Wall 106, therefore open communication corrugate fin, with except fuel tank sidewall 106, the title of opening is set to oil outlet 108.
The present invention also provides a kind of corrugated tank of transformer, including oil tank bottom plate and oil described in any one of the above embodiments simultaneously

It should be noted that the leakproofness of welding when connecing.Fuel tank sidewall 106 outside, including oil tank bottom plate 107, intersects the welding that is staggered, due to existing
There is no the height plus lengthening section 103, oil tank bottom plate 107 and fuel tank sidewall 106 in 106 vertical direction of fuel tank sidewall for having technology
The Partial Height of welding is shorter, therefore vertical direction top tank side wall 106 and oil tank bottom plate 107 are staggered 5mm welding when welding,
It is exactly that continuously welding is formed outside fuel tank with oil tank bottom plate 107 for one end of separate corrugate fin in 106 vertical direction of fuel tank sidewall
Sealing wire 111b, the then one end of oil tank bottom plate 107 far from vertical bottom and the welding of fuel tank sidewall 106 form fuel tank outside weld wiring
111a inevitably can since the vertical height after the removing corrugate fin of pervious fuel tank sidewall 106 falls short of when welding
Make corrugate fin opening i.e. oil outlet 108 also on sealing wire 111, therefore sealing wire 111 must all be skipped when welding
Oil outlet 108 causes sealing wire 111 discontinuous, and optimum efficiency cannot be reached by also having led to welding effect.
