Abstract

A heat dissipater for a CPU (Central Processing Unit) includes an upper block and a lower block abutting each other. The upper block has a series of fins extending upward from a first side of the upper block and a recess defined in a second side of the upper block. The lower block includes a first side having a recess defined to correspond to the recess in the upper block and forming a closed chamber with the recess in the upper block and a second side adapted to abut the CPU. Volatile liquid is received in the closed chamber to promote the heat dissipation of the heat dissipater for a CPU.
