PROBLEM TO BE SOLVED: To provide a coupling fin capable of greatly increasing the heat exchanging area per unit area of a heated surface for increasing the heat exchange efficiency. SOLUTION: Heat radiation fins 2 formed of their sections taking almost letter L shape are integrated by connecting respective base parts 4 so as to be joined with one another so that the heat radiation parts 3 of respective heat radiation fins 2 may be easily connected so as to narrow the intervals between the heat radiation parts 3. Accordingly, the installed numbers of the radiation fins in a limited space can be increased. Resultantly, the heat exchange area per unit area of a heated surface can be notably increased, thereby enabling the heat exchange efficiency of a coupling fin 1 to be enhanced.
