Description

Radiator fin structure

The present invention relates to a heat sink fin structure, which refers to a transformer heat sink, which can solve the situation that the heat sink temperature is too high, so as to improve the cooling efficiency of the heat sink.

When the transformer is running, a large amount of heat is generated. Therefore, in order to remove the generated heat, a heat sink is disposed outside the transformer body, and the heat dissipation area is increased to accelerate the heat removal to the environment.

Generally, the spacing of the heat sink fins is designed to be a fixed pitch due to the convenience of processing. However, because the temperature field distribution of the heat sink is not uniform, the temperature closer to the transformer end will be higher, and the temperature away from the transformer end will be higher. Will be lower.

Based on the above reasons, there is still room for improvement in the prior art. In view of this, the creator has actively studied and developed the experience of related product research and development for many years, and through continuous experimentation and improvement, finally developed this creation.

The main purpose of the present invention is to provide a heat sink fin structure, which can solve the problem that the heat sink temperature is too high, so as to improve the cooling efficiency of the heat sink.

In order to achieve the above purpose, the present invention provides a heat sink fin structure which is disposed outside the transformer and includes an oil flow pipe, a lower oil flow pipe and a plurality of heat dissipation fins. The heat dissipating fin is installed between the oil flow pipe and the lower oil flow pipe, and forms a connection relationship with the oil flow pipe and the lower oil flow pipe; the heat sink fin structure of the heat sink is characterized in that The spacing of the heat sink fins near the transformer end increases the volume of air flowing into the heat sink to increase the cooling efficiency, thereby reducing the number of heat sink fins and reducing the weight of the heat sink and the amount of oil of the insulating oil.

In order to further understand the features and technical contents of the present invention, please refer to the following detailed description and drawings of the present invention. However, the drawings are for reference and description only, and are not intended to limit the creation.

Please refer to FIG. 1 to FIG. 3 . FIG. 1 is a perspective view of a heat sink fin structure device in a transformer, and FIG. 2 is a side view of the heat sink fin structure device in the transformer. A perspective view of the heat sink fin structure is as shown in the figure: a heat sink fin structure is disposed outside the transformer 10, and includes an upper oil flow tube 21, a lower oil flow tube 22 and a plurality of heat dissipation fins 23; The oil flow pipe 21 has an oil inlet 211 for supplying the insulating oil inside the transformer 10 to the radiator 20, and the lower oil flow pipe 22 has an oil outlet 221 for returning the insulating oil to the inside of the transformer 10; The fin 23 is welded between the upper oil flow pipe 21 and the lower oil flow pipe 22, and is connected to the upper oil flow pipe 21 and the lower oil flow pipe 22.

When the insulating oil inside the transformer 10 is thermally expanded, it rises to the upper portion of the transformer 10, and flows into the heat sink 20 through the oil inlet 211 of the upper oil flow pipe 21, and the insulating oil flows evenly to the plurality of heat radiating fins 23 In order to dissipate heat, finally, the oil outlet 221 of the lower oil flow pipe 22 flows into the inside of the transformer 10 to form a heat dissipation cycle.

The heat sink fin structure is characterized in that the distance between the heat radiating fins 23 near the end of the transformer 10 is increased, and the volume of air flowing into the heat sink 20 is increased to improve the cooling efficiency, thereby reducing the number of the heat radiating fins 23, and The weight of the heat sink 20 and the amount of oil of the insulating oil are reduced to achieve the most economical fin structure design.

The above-described embodiments are merely examples for convenience of description, and the scope of the claims is intended to be limited to the above embodiments.

Although the present invention has been disclosed in the above preferred embodiments, it is not intended to limit the present invention, and anyone skilled in the art can make some changes and refinements without departing from the spirit and scope of the present invention. The scope of protection is subject to the definition of the scope of the patent application.
