Metal radiating fin Technical Field The utility model relates to the technical field of radiating fins, in particular to a metal radiating fin. Background In many fields of electronic equipment, industrial machinery and the like, a metal radiating fin is a crucial radiating component, and the performance of the metal radiating fin is directly related to the operation stability and the service life of the equipment. The metal radiating fin can rapidly transfer heat generated by the heating source by virtue of good heat conduction performance of metal so as to maintain the equipment to work in a proper temperature environment. In order to meet diversified heat dissipation requirements, chinese patent publication No. CN222674755U discloses a metal heat sink splicing structure. The metal radiating fin splicing structure fixes the plurality of radiating fin bodies at the corresponding positions of the connecting seat through the inserting connection rod, so that the combined use of the plurality of radiating fins is realized. The splicing mode increases the flexibility of disassembling and assembling the radiating fin body to a certain extent. However, the existing metal radiating fin splicing structure has obvious defects.
