If the transformer cannot be cooled for a long time, it is easy to cause the transformer to spontaneously combust. Therefore, it is necessary to set up a device to effectively dissipate heat for the transformer.

[0003] The existing transformer heat dissipation device, such as a flame retardant high-voltage transformer disclosed in the patent application document with application number 202322391330.5, includes a shell, one side of the shell is provided with a first radiator suitable for the transformer, and the other side of the shell is provided with a second radiator suitable for the transformer; the first liquid outlet provided on the shell is connected to the first liquid inlet provided on the first radiator suitable for the transformer through a first pipe; the second liquid outlet provided on the first radiator suitable for the transformer is connected to the second liquid inlet provided on the second radiator suitable for the transformer through a second pipe; the third liquid outlet on the second radiator suitable for the transformer is connected to the third liquid inlet provided on the shell through a third pipe. This heat dissipation device for the transformer uses two radiators suitable for the transformer to guide the circulation of liquid inside the shell to dissipate heat, enhance the work of the oil pump inside the transformer, and requires regular inspection to avoid leakage, and the cost of operation and maintenance is high.

[0022] Embodiment 1:

[0023] This embodiment provides a heat sink suitable for a transformer, such as Figure 1-Figure 2 As shown, it includes a connection barrel 1 connected to the outer periphery of the transformer, and the shape and size of the connection barrel 1 are adapted to the transformer. A plurality of heat dissipation fins 2 are arranged around the connection barrel 1, and the heat dissipation fins 2 are arranged along the height direction of the connection barrel 1, and the heat dissipation fins 2 are equal to the height of the connection barrel 1. One side of the heat dissipation fin 2 is connected to the connection barrel 1 and the other side is extended to a side away from the connection barrel 1.

[0024] When the radiator of this embodiment is installed on the transformer, it is tightly connected to the outside of the transformer through the connecting tube 1, and the connecting tube 1 is installed in coordination with the transformer. The multiple heat dissipation fins 2 around the connecting tube 1 are dispersed and extended outward to increase the heat dissipation area, and the heat of the transformer is transferred to the heat dissipation fins through the connecting tube 1, so that the heat of the transformer is quickly extracted and dispersed, and the transformer is effectively cooled to prevent the equipment from malfunctioning due to high temperature. The heat dissipation fins are evenly distributed, so that they can evenly dissipate heat around the transformer, thereby improving the heat dissipation efficiency. Compared with the existing heat dissipation method through liquid circulation, there is no need to drive the liquid to flow, and there is no need to consider whether the liquid leaks, which is more economical and has a simple structure.

[0025] The radiator of this embodiment can also be used for other equipment that needs heat dissipation. During installation, the connecting tube can be directly sleeved on the housing of the equipment, which is convenient for installation.

[0026] In some embodiments, the heat dissipation fin 2 includes a first fin 21 and a plurality of second fins 22. One side of the first fin 21 is connected to the connecting barrel 1 and the other side is connected to the plurality of second fins 22. One side of the plurality of second fins 22 is connected to the first fin 21 and the other side is extended in a direction away from the connecting barrel 1, and the plurality of second fins 22 are symmetrically arranged with the first fin 21 as the center line. The thickness of the second fin 22 can be less than the thickness of the first fin 21, so that the plurality of second fins 22 are dispersed.

[0027] The heat dissipation fins 2 in this embodiment are provided with a first fin 21 and a plurality of second fins 22. The connecting tube 1 transfers heat to the first fin 21, and then transfers heat to the plurality of second fins 22 through the first fin 21, so that the peripheral space of the connecting tube 1 is fully utilized, and the heat dissipation area is gradually increased in the process of heat conduction to the outside, and the heat dissipation area is further increased, so that the heat dissipation effect is further improved.

[0028] In some embodiments, the angles between two adjacent second fins 22 are equal. As the number of second fins 22 increases, the angles between two adjacent second fins 22 decrease. Preferably, three second fins 22 are provided, one of which is on the same straight line as the first fin 21, and the two second fins 22 are symmetrically arranged with respect to the first fin 21. It should be noted that two, four or five second fins 22 may also be provided.

[0029] In some embodiments, when the heat dissipation fins 2 are arranged around the connection tube 1, the second fins 22 of two adjacent heat dissipation fins 2 abut against each other. The second fins 22 are evenly arranged outside the connection tube 1, and there is no gap between two adjacent heat dissipation fins 2, so as to fully utilize the outer space of the connection tube 1.

[0030] In some embodiments, the connecting tube 1 is a cylindrical structure with upper and lower openings, so as to be suitable for a cylindrical transformer. When installing, the connecting tube 1 can be directly sleeved on the outside of the transformer, which is convenient for installation. The structure with upper and lower openings can dissipate heat through air. A plurality of heat dissipation fins 2 are arranged to diverge outwards with the central axis of the connecting tube 1 as the center.

[0031] In some embodiments, the first mounting plate 3 and the second mounting plate 4 of the same height as the connecting tube 1 are connected to the front and rear sides of the connecting tube 1, respectively, and the first mounting plate 3 and the second mounting plate 4 are symmetrically arranged about the center line of the connecting tube 1. The four corners of the first mounting plate 3 and the second mounting plate 4 are respectively provided with mounting holes 41, which are circular holes with a diameter of 10 mm, so as to facilitate the installation of the transformer, and further connect the transformer with the first mounting plate 3 and the second mounting plate 4 to make the connection more firm. The first mounting plate 3 and the second mounting plate 4 are both rectangular aluminum plates with a thickness of 3 mm, and have a good heat dissipation effect.

[0032] In some embodiments, the plurality of heat dissipation fins 2 are respectively connected to the left and right sides of the connection barrel 1, and the plurality of heat dissipation fins 2 on the left and right sides are symmetrical about the midline of the first mounting plate 3 and the second mounting plate 4. The second fins 22 of the plurality of heat dissipation fins 2, the first mounting plate 3 and the second mounting plate 4 are arranged around a circumference of the connection barrel 1.

[0033] In some embodiments, the heat sink 2 is an aluminum sheet with an integrated structure. Aluminum has good thermal conductivity and good heat dissipation. The heat sink 2 is an integrated pure aluminum heat sink. Compared with the traditional single-piece heat sink design, it has obvious heat dissipation advantages. Heat can be quickly dispersed to prevent high temperature of the device.

[0034] The above is only a preferred embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make several modifications and improvements without departing from the creative concept of the present invention, which should be included in the protection scope of the present invention.
