Description

Technical Field

[0001] This utility model belongs to the field of transformer heat dissipation technology, specifically relating to a gooseneck fin radiator and an oil-immersed transformer. Background Technology

[0002] The compact, wide-range, voltage- and capacity-regulating vehicle-mounted de-icing transformer is a special-purpose transformer used by power grid users to address the erosion and damage to the power grid caused by snow and ice disasters, as well as to meet the de-icing needs of power plants. It belongs to the rectifier transformer category within industrial transformers. This transformer is used outdoors, mounted entirely on a vehicle platform, and sometimes needs to be moved via the platform. When the vehicle travels on bumpy roads, it causes the transformer to vibrate, which in turn causes the radiator to vibrate.

[0003] In existing radiators, the heat sink fins are usually fixed to the outside of the transformer tank only through the connection point with the oil collection pipe. The fixing strength of the heat sink fins is low, and they may deform and be damaged when the radiator vibrates. Utility Model Content

[0004] The technical problem to be solved by this utility model is to address the above-mentioned deficiencies in the existing technology by providing a gooseneck fin radiator and an oil-immersed transformer. By setting a reinforcing component on the support component of the heat dissipation component, it is not necessary to consider the influence of the installation method and position of the heat dissipation fin on the reinforcing component. By reinforcing the heat dissipation fin with the reinforcing component, it is possible to prevent the heat dissipation fin from deforming and being damaged during vibration.

[0005] The inventors have also discovered that the installation position of the heat sink fins in existing radiators (which are far from the transformer tank) and their sequential arrangement make it difficult to secure the heat sink fins to the transformer tank using ordinary reinforcing components (such as screws). The reinforcing component in this application, however, does not require consideration of the influence of the heat sink fin installation method and position on the reinforcing component, and can still achieve the goal of reinforcing the heat sink fins.

[0006] In a first aspect, this utility model provides a gooseneck finned radiator for oil-immersed transformers. The gooseneck finned radiator includes a heat dissipation assembly and a reinforcing assembly. The heat dissipation assembly includes a first heat dissipation fin and a second heat dissipation fin, the second heat dissipation fin being longer than the first heat dissipation fin. There are multiple first heat dissipation fins arranged sequentially in a row. There are also multiple second heat dissipation fins arranged sequentially after the first heat dissipation fins and in the same row as the first heat dissipation fins. The reinforcing assembly includes a first reinforcing rib. The first reinforcing rib is disposed above the first heat dissipation fins and is fixedly connected to the outermost first heat dissipation fin, the innermost second heat dissipation fin, and the support assembly of the heat dissipation assembly.

[0007] In some embodiments, the reinforcing component further includes a second reinforcing rib. The second reinforcing rib is horizontally disposed above the second heat sink, connecting the top ends of a plurality of second heat sinks into one unit, and is fixedly connected to the support component of the heat dissipation component.

[0008] In some embodiments, the number of the second heat sinks is n1, where n1 is a positive integer. The number of second heat sinks connected to each of the second reinforcing ribs is n2, where n2 is a positive integer, 3 ≤ n2 ≤ 8, and n2 ≤ n1.

[0009] In some embodiments, the number of the second reinforcing ribs is multiple. The multiple second reinforcing ribs are in the shape of a broken line.

[0010] In some embodiments, the gooseneck fin radiator further includes a support assembly. The support assembly includes an upper oil collection pipe and a lower oil collection pipe. The upper oil collection pipe has a reverse-oriented Z-shape and includes a first horizontal pipe, a connecting pipe, and a second horizontal pipe connected in sequence, with the connecting pipe being vertically arranged. The lower oil collection pipe includes a third horizontal pipe, with both ends of the first heat sink connected between the first horizontal pipe and the third horizontal pipe, and both ends of the second heat sink connected between the second horizontal pipe and the third horizontal pipe.

[0011] In some embodiments, the reinforcing assembly further includes a third reinforcing rib, a fourth reinforcing rib, and a fifth reinforcing rib. The third reinforcing rib is horizontally disposed at the top end of the side of the second heat sink and connected to the side of each of the second heat sinks. The fourth reinforcing rib is horizontally disposed at the top end of the side of the first heat sink and connected to the side of each of the first heat sinks, extending to connect to the side of each of the second heat sinks. The fifth reinforcing rib is horizontally disposed at the bottom end of the side of the heat dissipation assembly and connected to the side of each of the first and second heat sinks.

[0012] In some embodiments, the reinforcing assembly further includes a sixth reinforcing rib and a seventh reinforcing rib. The sixth reinforcing rib is horizontally disposed between the fourth and fifth reinforcing ribs and is connected to the side of each of the first and second heat sinks. There are two seventh reinforcing ribs, which are obliquely and symmetrically disposed on both sides of the sixth reinforcing rib, and each seventh reinforcing rib is connected to the side of each of the first and second heat sinks.

[0013] In some embodiments, the height difference between the first heat sink and the second heat sink is H, where H ≥ 400 mm. The reinforcing assembly further includes an eighth reinforcing rib; the eighth reinforcing rib is located at the position where the height of the second heat sink exceeds that of the first heat sink, and the eighth reinforcing rib is connected to the side of each of the second heat sinks.

[0014] In some embodiments, the reinforcement assembly further includes an oil collection pipe reinforcing plate. The oil collection pipe reinforcing plate is disposed at the connection position of the first horizontal pipe and the connecting pipe, and is connected to both the first horizontal pipe and the connecting pipe; or, the oil collection pipe reinforcing plate is shaped like a reverse-oriented Z-shape and is disposed along the outer surface of the upper oil collection pipe, and is connected to the upper surface of the first horizontal pipe, the outer surface of the connecting pipe, and the upper surface of the second horizontal pipe.

[0015] Therefore, the gooseneck fin radiator provided in this embodiment of the invention, due to the presence of a reinforcing component, can prevent the fins from deforming and being damaged during vibration. Multiple first fins are arranged in a row, and multiple second fins are arranged in a row following the first fins. By providing the reinforcing component and placing the first reinforcing rib above the first fins, the first reinforcing rib is fixedly connected to the outermost first fin, the innermost second fin, and the support component of the heat dissipation assembly. This eliminates the need to consider the influence of the fin installation method and position on the reinforcing component. Furthermore, the outermost first fin and the innermost second fin are fixed to the support component of the heat dissipation assembly by the first reinforcing rib. Therefore, the support component and the first reinforcing rib reinforce the outermost first fin and the innermost second fin, increasing their strength and preventing deformation and damage during vibration.

[0016] Secondly, this utility model embodiment provides an oil-immersed transformer, which includes an oil tank, a transformer body, and the gooseneck fin radiator mentioned in the first aspect. The oil tank is used to store insulating oil. The transformer body is disposed inside the oil tank and immersed in the insulating oil. The gooseneck fin radiator is disposed outside the oil tank and communicates with the insulating oil inside the oil tank for dissipating heat from the insulating oil inside the tank.

[0017] The oil-immersed transformer provided in this embodiment of the invention has the same beneficial effects as the gooseneck fin radiator described above, and will not be repeated here. Attached Figure Description

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1:

[0026] like Figure 1 As shown, this utility model embodiment provides a gooseneck fin radiator, which is applied in an oil-immersed transformer to dissipate heat from the insulating oil in the transformer.

[0027] For example, the oil-immersed transformer can be a compact, wide-range voltage and capacity adjustable vehicle-mounted de-icing transformer, which can be used to cope with the erosion and damage to the power grid caused by ice and snow disasters and solve the de-icing needs of power plants.

[0028] like Figure 1 As shown, the gooseneck fin radiator includes a heat dissipation assembly 3 and a reinforcing assembly 4. The heat dissipation assembly 3 includes a first heat dissipation fin 31 and a second heat dissipation fin 32, the second heat dissipation fin being longer than the first heat dissipation fin 31. There are multiple first heat dissipation fins 31 arranged in a row. There are also multiple second heat dissipation fins 32 arranged in a row after the first heat dissipation fins 31. The reinforcing assembly 4 includes a first reinforcing rib 41; the first reinforcing rib 41 is disposed above the first heat dissipation fin 31 and is respectively connected to the outermost (… Figure 1 The leftmost heat sink 31, the innermost second heat sink 32, and the support component of the heat dissipation assembly 3 are fixedly connected.

[0029] For example, both the first heat sink 31 and the second heat sink 32 are connected to the oil tank of the oil-immersed transformer through pipes. Both the first heat sink 31 and the second heat sink 32 are provided with heat dissipation channels. The insulating oil in the oil tank of the oil-immersed transformer is cooled after passing through the heat dissipation channels in the first heat sink 31 and the second heat sink 32.

[0030] For example, the length of the first heat sink 31 and the length of the second heat sink 32 are determined according to the model and size of the transformer, so that the first heat sink 31 and the second heat sink 32 meet the requirements for heat dissipation of the insulating oil.

[0031] In some examples, the length of the first heat sink 31 is 1.5m and the length of the second heat sink 32 is 2.3m.

[0032] For example, such as Figure 1 As shown, the plane containing the first heat sink 31 and the plane containing the second heat sink 32 are both vertically arranged and parallel to each other. Multiple first heat sinks 31 are arranged along... Figure 1 Arranged sequentially from left to right, multiple second heat sinks 32 are located to the right of the first heat sink 31, and along... Figure 1 Arranged sequentially from left to right in the middle.

[0033] For example, in all the first heat sinks 31 and / or all the second heat sinks 32, the spacing between any two adjacent ones is the same, for example, the spacing can be set to 45±1mm.

[0034] For example, in combination Figure 1 , Figure 2 and Figure 3 The widths of the first heat sink 31 and the second heat sink 32 are the same; both the first heat sink 31 and the second heat sink 32 are axisymmetric images, and their axes of symmetry are their vertical center lines. Their respective vertical center lines are arranged in a row to form a vertical plane.

[0035] For example, in combination Figure 1 and Figure 3 The number of reinforcing components 4 can be two sets. The two sets of reinforcing components 4 are symmetrically arranged on the heat dissipation component 3 with the vertical plane as the center, so as to reinforce the heat dissipation component 3.

[0036] For example, the support component of the heat dissipation component 3 can be a common bracket, which has high strength and stability.

[0037] For example, the outermost first heat sink 31 is... Figure 1 The first heat sink 31, which is furthest from the second heat sink 32, and the second heat sink 32, which is the innermost, are... Figure 1 The second heat sink 32 is adjacent to the first heat sink 31.

[0038] For example, the first reinforcing rib 41 can be a metal plate or metal strip, etc., and the first reinforcing rib 41 can be fixedly connected to the outermost first heat sink 31, the innermost second heat sink 32 and the support component of the heat dissipation assembly 3 by welding.

[0039] For example, such as Figure 1 As shown, the support components of the heat dissipation assembly 3 may include the upper oil collecting pipe 1 and the lower oil collecting pipe 2, which are described later. The upper oil collecting pipe 1 and the lower oil collecting pipe 2 are fixed on the oil tank of the oil-immersed transformer. At this time, the first reinforcing rib 41 can be fixed on the first horizontal pipe 11 of the upper oil collecting pipe 1 so that the outermost first heat dissipation fin 31 and the innermost second heat dissipation fin 32 are both fixed on the first horizontal pipe 11.

[0040] Combination Figure 1 , Figure 2 and Figure 3 The first reinforcing rib 41 can fix the outermost first heat sink 31 and the innermost second heat sink 32 to the support component of the heat dissipation assembly 3. Therefore, the outermost first heat sink 31 and the innermost second heat sink 32 can be reinforced by the support component of the heat dissipation assembly 3 and the first reinforcing rib 41 to increase the strength of the outermost first heat sink 31 and the innermost second heat sink 32, and to prevent the outermost first heat sink 31 and the innermost second heat sink 32 from deforming and being damaged during vibration.

[0041] For example, such as Figure 1 and Figure 3 As shown, the first reinforcing rib 41 is connected to the top center of the outermost first heat sink 31, and the first reinforcing rib 41 is connected to the side of the innermost second heat sink 32. Figure 3 In the top view of the gooseneck fin radiator, the first reinforcing rib 41 is shaped as a diagonal line, which can provide better reinforcement to the side of the innermost second heat sink 32.

[0042] For example, in Figure 1 In the first reinforcing rib 41, the connection point between the first reinforcing rib 41 and the outermost first heat sink 31 is the lowest point of the first reinforcing rib 41, and the connection point between the first reinforcing rib 41 and the innermost second heat sink 32 is the highest point of the first reinforcing rib 41. The height difference between the lowest point and the highest point of the first reinforcing rib 41 is less than or equal to 50mm, so as to avoid the first reinforcing rib 41 having too large a span due to the large height difference between the lowest point and the highest point of the first reinforcing rib 41, thereby avoiding affecting the strength of the first reinforcing rib 41 itself.

[0043] Therefore, in the gooseneck fin radiator provided by this utility model embodiment, multiple first heat sinks 31 are arranged in a row, and multiple second heat sinks 32 are arranged in a row after the first heat sinks 31. By setting a reinforcing component 4 and placing the first reinforcing rib 41 in the reinforcing component 4 above the first heat sinks 31, the first reinforcing rib 41 is fixedly connected to the outermost first heat sink 31, the innermost second heat sink 32, and the support component of the heat dissipation component 3, respectively. This eliminates the need to consider the installation method of the heat sinks and the installation process. The installation position affects the reinforcement component 4, and the outermost first heat sink 31 and the innermost second heat sink 32 can be fixed to the support component of the heat dissipation component 3 by the first reinforcing rib 41. Therefore, the outermost first heat sink 31 and the innermost second heat sink 32 can be reinforced by the support component of the heat dissipation component 3 and the first reinforcing rib 41 to increase the strength of the outermost first heat sink 31 and the innermost second heat sink 32, thereby avoiding deformation and damage of the outermost first heat sink 31 and the innermost second heat sink 32 when they vibrate.

[0044] In some embodiments, such as Figure 1 and Figure 3 As shown, the reinforcing component 4 also includes a second reinforcing rib 42. The second reinforcing rib 42 is horizontally disposed above the second heat sink 32, connecting the top ends of the plurality of second heat sinks 32 into one piece, and is fixedly connected to the support component of the heat dissipation component 3.

[0045] For example, the second reinforcing rib 42 can be a metal plate or a metal strip, and the second reinforcing rib 42 can be connected to the top of the second heat sink 32 and the support component of the heat dissipation assembly 3 by welding.

[0046] For example, such as Figure 1 and Figure 3 As shown, when the support component of the heat dissipation assembly 3 includes an upper oil collection pipe 1 and a lower oil collection pipe 2, the second reinforcing rib 42 can be fixed on the second horizontal pipe 13 of the upper oil collection pipe 1 so that the top ends of the plurality of second heat dissipation fins 32 are fixed on the second horizontal pipe 13.

[0047] Understandably, the second reinforcing rib 42 is located on the top surface of the second heat sink 32.

[0048] With the above configuration, the top ends of multiple second heat sinks 32 can be fixed to the support component of the heat dissipation assembly 3 by the second reinforcing rib 42, thereby improving the fixing strength of the top ends of multiple second heat sinks 32 and preventing the top ends of the second heat sinks 32 from deforming and being damaged when vibrating.

[0049] In some embodiments, such as Figure 1 and Figure 3As shown, the number of second heat sinks 32 is n1, where n1 is a positive integer. The number of second heat sinks 32 connected to each second reinforcing rib 42 is n2, where n2 is a positive integer, 3≤n2≤8, and n2≤n1.

[0050] For example, the number n1 of the second heat sink 32 can be set according to factors such as the size of the gooseneck heat sink and the spacing between adjacent second heat sinks 32. Figure 1 The image shows 11 second heat sinks 32. Figure 3 The image shows seven second heat sinks 32.

[0051] For example, the number n2 of the second heat sinks 32 connected to each second reinforcing rib 42 can be 3, 5 or 8, etc.

[0052] For example, such as Figure 3 As shown, there are 3 second heat sinks 32 connected to one second reinforcing rib 42, and 4 second heat sinks 32 connected to another second reinforcing rib 42. The distance between the two second reinforcing ribs 42 is 20mm.

[0053] Understandable, such as Figure 3 As shown, only one end of the second reinforcing rib 42 is connected to the support component (second horizontal pipe 13) of the heat dissipation assembly 3. The more second heat dissipation fins 32 connected to the second reinforcing rib 42, the greater the span (length) of the second reinforcing rib 42 must be. If the span of the second reinforcing rib 42 is too large, it will affect the strength of the second reinforcing rib 42 itself, and thus the strength of the second reinforcing ribs 42 connected to it. By limiting the number of second heat dissipation fins 32 connected to each second reinforcing rib 42 to the above range, it is possible to avoid the span (length) of the second reinforcing rib 42 being too large and affecting its own strength, thereby ensuring the fixing and reinforcing effect of the second reinforcing rib 42 on the second heat dissipation fins 32.

[0054] In some embodiments, the number of second reinforcing ribs 42 is multiple; the multiple second reinforcing ribs 42 are in the shape of a broken line.

[0055] When the number of second heat sinks 32 connected to a second reinforcing rib 42 is fixed, the more total number of second heat sinks 32 there are, the more second reinforcing ribs 42 need to be provided.

[0056] For example, when the total number of second heat sinks 32 is different, the number of second reinforcing ribs 42 can be two, three, or four, etc.

[0057] Normally, the closer the top of the second heat sink 32 is to the edge, the greater the amplitude of vibration when subjected to vibration, and the greater the possibility of deformation and damage. By setting the shape of the multiple second reinforcing ribs 42 to a zigzag shape, the part of the second reinforcing ribs 42 extending to the top edge of the second heat sink 32 can play a better role in fixing and reinforcing the top edge of the second heat sink 32, and avoid deformation and damage to the top edge of the second heat sink 32 when it vibrates.

[0058] In some embodiments, such as Figure 1 As shown, the gooseneck fin radiator also includes a support assembly. The support assembly includes an upper oil collection pipe 1 and a lower oil collection pipe 2. The upper oil collection pipe 1 is shaped like a reverse-oriented Z and includes a first horizontal pipe 11, a connecting pipe 12, and a second horizontal pipe 13 connected in sequence, with the connecting pipe 12 being vertically arranged. The lower oil collection pipe 2 includes a third horizontal pipe, with the two ends of the first heat sink 31 connected between the first horizontal pipe 11 and the third horizontal pipe, and the two ends of the second heat sink 32 connected between the second horizontal pipe 13 and the third horizontal pipe, respectively.

[0059] For example, the lower oil collection pipe 2 is located directly below the upper oil collection pipe 1. The bottom ends of the first heat sink 31 and the second heat sink 32 are flush.

[0060] For example, both the upper oil collection pipe 1 and the lower oil collection pipe 2 are fixed to the outside of the oil tank of the gooseneck fin radiator.

[0061] For example, Figure 1 In the middle, both the upper oil collection pipe 1 and the lower oil collection pipe 2 are connected to the inside of the oil tank of the gooseneck fin radiator. The insulating oil in the oil tank flows out through the upper oil collection pipe 1, and then flows back into the oil tank through the heat dissipation component 3 and the lower oil collection pipe 2.

[0062] With the above configuration, the upper oil collection pipe 1 and the lower oil collection pipe 2 can provide support for the first heat sink 31, the second heat sink 32, the first reinforcing rib 41, and the second reinforcing rib 42, and allow the insulating oil in the oil tank to be cooled through the heat dissipation assembly 3.

[0063] In some embodiments, such as Figure 1 As shown, the reinforcing component 4 also includes a third reinforcing rib 43, a fourth reinforcing rib 44, and a fifth reinforcing rib 45. The third reinforcing rib 43 is horizontally disposed at the top end of the side of each second heat sink 32 and is connected to the side of each second heat sink 32. The fourth reinforcing rib 44 is horizontally disposed at the top end of the side of each first heat sink 31 and is connected to the side of each first heat sink 31, extending to connect with the side of each second heat sink 32. The fifth reinforcing rib 45 is horizontally disposed at the bottom end of the side of the heat dissipation component 3 and is connected to the side of each first heat sink 31 and the side of each second heat sink 32.

[0064] For example, the third reinforcing rib 43, the fourth reinforcing rib 44 and the fifth reinforcing rib 45 can all be metal strips or metal plates, and are connected to the first heat sink 31 and / or the second heat sink 32 by welding.

[0065] like Figure 1 and Figure 3 As shown, the third reinforcing rib 43 can reinforce the top edges of all the second heat sinks 32, preventing deformation and damage to the top edges of the second heat sinks 32 during vibration. The fourth reinforcing rib 44 can reinforce the top edges of the first heat sink 31 and the middle parts of the sides of the second heat sinks 32, preventing deformation and damage to the top edges of the first heat sink 31 and the middle parts of the sides of the second heat sinks 32 during vibration. The fifth reinforcing rib 45 can reinforce the bottom edges of the first heat sink 31 and the bottom edges of each second heat sink 32, preventing deformation and damage to the bottom edges of the first heat sink 31 and the bottom edges of each second heat sink 32 during vibration.

[0066] In some embodiments, such as Figure 1 As shown, the reinforcing component 4 also includes a sixth reinforcing rib 46 and a seventh reinforcing rib 47. The sixth reinforcing rib 46 is horizontally disposed between the fourth reinforcing rib 44 and the fifth reinforcing rib 45, and is connected to the side of each first heat sink 31 and the side of each second heat sink 32. There are two seventh reinforcing ribs 47, which are inclined and symmetrically disposed on both sides of the sixth reinforcing rib 46, and each seventh reinforcing rib 47 is connected to the side of each first heat sink 31 and the side of each second heat sink 32.

[0067] For example, the sixth reinforcing rib 46 and the seventh reinforcing rib 47 can both be metal strips or metal plates, and are connected to the first heat sink 31 and the second heat sink 32 by welding.

[0068] For example, the sixth reinforcing rib 46 is disposed at the center position between the fourth reinforcing rib 44 and the fifth reinforcing rib 45.

[0069] For example, the angle α between the seventh reinforcing rib 47 and the horizontal plane can be: 30°≤a≤60°.

[0070] With the above configuration, the first heat sink 31 and the second heat sink 32 can be connected into a whole by the sixth reinforcing rib 46 and the seventh reinforcing rib 47 to reinforce the sides of the first heat sink 31 and the second heat sink 32 and prevent the sides of the first heat sink 31 and the second heat sink 32 from deforming and being damaged during vibration.

[0071] In some other examples, when the distance (height difference) between the fourth reinforcing rib 44 and the fifth reinforcing rib 45 is too large (e.g., more than 2m), the number of sixth reinforcing ribs 46 can also be set to multiple. The distance S between two adjacent sixth reinforcing ribs 46 can be set to: 600mm≤S≤750mm. In this case, a seventh reinforcing rib 47 can also be set between two adjacent sixth reinforcing ribs 46.

[0072] In some embodiments, such as Figure 1 As shown, the height difference between the first heat sink 31 and the second heat sink 32 is H, where H ≥ 400 mm. The reinforcing component 4 also includes an eighth reinforcing rib 48; the eighth reinforcing rib 48 is located at the position where the height of the second heat sink 32 exceeds that of the first heat sink 31, and the eighth reinforcing rib 48 is connected to the side of each second heat sink 32.

[0073] For example, the eighth reinforcing rib 48 can be a metal strip or a metal plate, and is connected to the side of the second heat sink 32 by welding.

[0074] With the above configuration, the portion of the second heat sink 32 that extends beyond the first heat sink 31 can be reinforced by the eighth reinforcing rib 48, so as to prevent the portion of the second heat sink 32 that extends beyond the first heat sink 31 from being too long and deformed or damaged during vibration.

[0075] In some embodiments, such as Figure 1 As shown, the reinforcement component 4 also includes an oil collection pipe reinforcing plate 49; the oil collection pipe reinforcing plate 49 is disposed at the connection position of the first horizontal pipe 11 and the connecting pipe 12, and is connected to both the first horizontal pipe 11 and the connecting pipe 12.

[0076] For example, the oil collection pipe reinforcing plate 49 can be a metal plate, such as No. 20 steel plate or Q235B steel.

[0077] For example, the shape of the oil collecting pipe reinforcing plate 49 can be triangular or rectangular. Figure 1 The image shows a triangular oil collection pipe reinforcement plate 49.

[0078] With the above settings, the connection position of the first horizontal pipe 11 and the connecting pipe 12 can be strengthened by the oil collection pipe reinforcing plate 49, so as to prevent the connection position of the first horizontal pipe 11 and the connecting pipe 12 from cracking or deforming during vibration.

[0079] In other examples, the oil collection pipe reinforcing plate 49 is shaped like a reverse Z and is disposed along the outer surface of the upper oil collection pipe 1. The oil collection pipe reinforcing plate 49 is connected to the upper surface of the first horizontal pipe 11, the outer surface of the connecting pipe 12, and the upper surface of the second horizontal pipe 13.

[0080] That is, the shape of the oil collecting pipe reinforcing plate 49 is the same as the shape of the upper oil collecting pipe 1.

[0081] With the above settings, the connection positions of the first horizontal pipe 11 and the connecting pipe 12, and the connection positions of the connecting pipe 12 and the second horizontal pipe 13 can be reinforced by the oil collection pipe reinforcing plate 49, so as to prevent cracking or deformation of the connection positions of the first horizontal pipe 11 and the connecting pipe 12, and the connection positions of the connecting pipe 12 and the second horizontal pipe 13 during vibration.

[0082] Example 2:

[0083] This utility model embodiment also provides an oil-immersed transformer, which includes an oil tank, a transformer body, and the gooseneck fin radiator from Embodiment 1. The oil tank is used to store insulating oil. The transformer body is disposed inside the oil tank and is immersed in the insulating oil. The gooseneck fin radiator is disposed outside the oil tank and communicates with the insulating oil inside the oil tank for dissipating heat from the insulating oil inside the tank.

[0084] For example, the oil-immersed transformer can be a compact, wide-range voltage and capacity adjustable vehicle-mounted de-icing transformer.

[0085] For example, the oil tank of the gooseneck fin radiator is provided with a support component for the heat dissipation component 3, and the reinforcing component 4 is fixed on the support component.

[0086] The insulating oil in the oil tank of the oil-immersed transformer can enter the heat dissipation component 3, dissipate heat as it flows through the heat dissipation component 3, and then flow back into the oil tank of the oil-immersed transformer, thereby achieving heat dissipation of the insulating oil.

[0087] The gooseneck fin radiator in Example 1 can enhance the strength of the first heat sink 31 and the second heat sink 32, and prevent the first heat sink 31 and the second heat sink 32 from deforming and being damaged when vibrating.
