10. A fin structure, comprising:
an inlet fin assembly, comprising:
a plurality of inlet fins, arranged side by side, wherein a first air channel is formed between two of the plurality of inlet fins that are adjacent to each other; and
an outlet fin assembly, comprising:
a plurality of outlet fins, arranged side by side, wherein a second air channel is formed between two of the plurality of outlet fins that are adjacent to each other, the inlet fin assembly is connected to the outlet fin assembly, and the plurality of first air channels are in fluid communication with the plurality of second air channels; and
wherein a thermal conductivity of the inlet fin assembly is greater than a thermal conductivity of the outlet fin assembly;
wherein a width of the plurality of first air channels are greater than or equal to a width of the plurality of second air channels;
wherein each of the plurality of inlet fins of the inlet fin assembly comprise a first top plate, a first bottom plate and a first side plate connecting the first top plate and the first bottom plate, the first top plate, the first bottom plate and the first side plate of one of the plurality of inlet fins and the first side plate of another one of the plurality of inlet fins adjacent thereto together form the first air channel, the inlet fin of the inlet fin assembly has a first length along an extending direction of a side connecting the first top plate and the first side plate, each of the plurality of outlet fins of the outlet fin assembly comprise a second top plate, a second bottom plate and a second side plate connecting the second top plate and the second bottom plate, the second top plate, the second bottom plate and the second side plate of one of the plurality of the outlet fins and the second side plate of another one of the plurality of outlet fins adjacent thereto together form the second air channel, the outlet fin of the outlet fin assembly has a second length along an extending direction of a side connecting the second top plate and the second side plate, the first length is one third to two third of a sum of the first length and the second length.
