As shown in Figure 3, it is the fin structure of the improved cooling seat proposed by the utility model, which includes a bottom plate 1 and fins 2 arranged in an arrangement, wherein:

The bottom plate 1 is a rectangular sheet made of metal materials such as copper or aluminum, and its surface is provided with a plurality of slots 11 (such as 4 to 7), for the insertion of the fins 2; the arrangement shape of the slots 11 can be changed and implemented according to the needs of the heat sink installation occasions, and is not limited to the above-mentioned states.

The fins 2 are made of metal sheets, preferably copper sheets; the invention of this utility model lies in the structure that the fins 2 are combined on the bottom plate 1, so that the fins 2 are planted on the bottom of the bottom plate 1. The slots 11 are erected in an arrangement, and are arranged in an easy-to-dissipate state by means of the combination structure of the fins 2 .
