A heat sink assembly (20) includes a number of parallel first fins (40)
and a number of parallel second fins (60) each having a main body (44,
64). A number of latch slots (46) is defined in the main body of each
first fin. A number of latches (66) extends from the main body of each second
fin in opposite directions. The first fins and the second fins are assembled together
in interleaved fashion, so that the latches of each second fin engage in the latch
slots of two adjacent first fins respectively.
