Abstract

A heat dissipating device includes a tubular body (2) having a first open end (211), and a plurality of heat dissipating fins (3), each having a fin body (31) and a first engaging portion (32) formed on the fin body (31) for engaging the first open end (211) of the tubular body (2) in a manner that the heat dissipating fins (3) are disposed to radiate from and to surround the tubular body (2). The first engaging portion (32) includes a first extension section (321) bent from the fin body (31), and a first hook (322) extending from the first extension section (321) for hooking onto the tubular body (2) at the first open end (211).
