Plug-in type cooling fin

The utility model relates to the field of radiating fin equipment, in particular to a plug-in type radiating fin. The plug-in type cooling fin comprises an embedded plate, fixing feet are integrally formed at the two ends of the embedded plate, a through groove is formed in the middle of the embedded plate, and limiting baffles are integrally formed in the positions, located on the front side and the rear side of the through groove, of the embedded plate. The middle plate is slidably inserted into a through groove formed in the embedding plate, a semiconductor chilling plate is embedded in the bottom end of the middle plate, a heat conduction rod is inserted into the upper surface of the middle plate by forming a plurality of inserting grooves, and single heat dissipation fins are inserted into the heat conduction rod; the clamping and blocking pieces used for clamping and blocking the middle plate are fixedly installed at the positions, located at the left end and the right end of the through groove, of the
