In a liquid-cooling system for a notebook personal computer having a body
part including a CPU and a chip set respectively mounted on a mother board
and an HDD, and a display part rotatably supported by the body part, a
heat receiving head is fixed to at least one heat generation part
including the CPU. A tube filled with cooling liquid is connected to the
heat receiving head. The tube connected to the heat receiving head is
disposed in series on at least one heat generation part including the chip
set so as to collect the heat generated from each heat generation part.
The tube is also laid in a meandering or zigzagging pattern between a
liquid crystal panel and a housing of the display part. The heat generated
from each heat generation part is absorbed at part of the tube by the
cooling liquid that circulates in the tube and functions as a heat
transfer medium. The absorbed heat is then radiated at another part of the
tube. Consequently, the heat generated from the chip set including the CPU
and other heat sources such as the HDD can be radiated together to the
outside. Local temperature rising is prevented. An uniform temperature
environment is attained on all the surfaces of the body part.
