[0056] In an embodiment of the utility model, a plurality of radiator units are provided on both sides of the transformer body 6, and the radiator units on each side are distributed in sequence along the side wall of the transformer body 6, and the radiator units include a heat sink 2 and an oil collecting pipe 1 connected to the heat sink 2, and the oil collecting pipe 1 and the heat sink 2 are reinforced by a connecting component 3.

[0057] Compared with the prior art, the gooseneck radiator provided in the embodiment of the utility model realizes heat dissipation of the transformer body 6 through multiple radiator units, and each radiator unit is composed of an oil collecting pipe 1 and a heat sink 2, and each oil collecting pipe 1 and heat sink 2 are reinforced and fixed by a corresponding connecting component 3.

[0058] In an optional implementation manner of this embodiment, refer to Figure 1 or Figure 3 The connection assembly 3 includes a first reinforcing plate 31 , one end of which is connected to the oil collecting pipe 1 , and the other end of which is connected to the corresponding heat sink 2 in turn.

[0059] Specifically: one end of the first reinforcing plate 31 is connected to the oil collecting pipe 1, and the other end is connected to the corresponding heat sinks 2 in turn; preferably, the first reinforcing plate 31 is welded to the outer wall of the oil collecting pipe 1, and the other end is connected to several adjacent heat sinks 2, so as to reduce the impact and damage of vibration on the equipment during transportation.

[0060] Further, refer to Figure 1 or Figure 4 The connection assembly 3 also includes a second reinforcing plate 32 ; a flange 11 is provided at the end of the oil collecting pipe 1 ; one end of the second reinforcing plate 32 is connected to the flange 11 , and the other end is connected to the corresponding heat sink 2 .

[0061] Specifically: one end of the second reinforcing plate 32 is connected to the flange 11, and the other end is connected to the corresponding heat sink 2; preferably, the lengths of the heat sinks 2 are different, and the lengths of the heat sinks 2 located at the front end are shorter than the heat sinks 2 located at the rear end, and the second reinforcing plate 32 is connected to the shorter heat sinks 2 at the front end in turn, and the connection method can be welding, so as to reduce the impact and damage of vibration on the equipment during transportation.

[0062] It should be noted that there are two second reinforcing plates 32 , and the two second reinforcing plates 32 are respectively connected to the flanges 11 of the oil collecting pipe 1 located at the top and the top of the heat sink 2 .

[0063] In an optional implementation manner of this embodiment, refer to Figure 1 or Figure 2 The heat sink monomer further includes a reinforcing rib 4, which is connected to the heat sink 2 of corresponding length along the second direction.

[0064] Specifically: the reinforcing ribs 4 are connected to the heat sinks 2 of corresponding lengths along the second direction; that is, at least two reinforcing ribs 4 are provided, one reinforcing rib 4 is sequentially connected to the shorter heat sink 2, and the other reinforcing rib 4 is sequentially connected to the longer heat sink 2.

[0065] The heat sink 2 is reinforced by two unconnected reinforcing ribs 4 , which effectively prevents vibration from being transmitted to the outermost heat sink 2 through the reinforcing ribs 4 .

[0068] It should be noted that the connecting plate 5 can be left in the process of using the equipment, so as to be used for reinforcement during use; specifically, during the operation of the transformer body 6, the magnetostriction of the silicon steel sheet causes the vibration of the iron core; when the load current passes through the winding, the electromagnetic force produced by the leakage magnetic flux between the winding conductors causes the vibration of the winding; the leakage magnetic flux causes the vibration of the oil tank wall (including magnetic shielding, etc.). Since the radiator monomer is connected to the oil tank of the transformer body 6, the vibration of the oil tank will drive the vibration of the radiator monomer at the same time. Since there are many groups of radiator monomers and the volume of each is relatively large, long-term vibration may cause the connection between the radiator monomer and the oil tank to become loose or cracked, posing a hidden danger to the safe operation of the product. Therefore, by arranging a connecting plate 5 on the upper part of the radiator monomer, each group of radiator monomers can be bound as a whole to reduce the impact of vibration.
