Abstract

A high thermal conductivity radiating fin for shielding electromagnetic wave comprises a shielding seat and a base. Multiple dovetail grooves are formed in the upper plane of the base. Dovetail convex strips are formed on the bottom of heat radiation fins. The dovetail convex strips are clamped in the dovetail grooves in an interference fit mode. An elongated through hole is formed in the base. Multiple vertical through holes are formed in the heat radiation fins. Multiple transverse through holes are formed in the lower portion of the heat radiation fins. The bottom of the base is inserted in a groove of the shielding seat. Connecting blocks are fixedly connected to the left and right sidewalls of the shielding seat through bolts. Supporting legs of connecting blocks are inserted and clamped in jacks formed in a circuit board. Each part of the radiating fin can be detached to satisfy different installation demands. When the radiating fins or the shielding seat need replacing, the connecting blocks don't have to be detached from the circuit board. Therefore the loosening of the jacks of the circuit board is prevented and the installation effect is guaranteed. In addition, the radiating fin can carry out heat exchange not only at exterior through heat radiation fin but also in interior.
