Patent ID: 7265975

Claim:
An improvement on a CPU heat dissipating device structure, comprising: a heat dissipating block contiguous an upper side of a CPU; the heat dissipating block having a holding room defined therein; a plurality of a first type of heat dissipating conduits joined to one end of the heat dissipating block, and communicating with the holding room of the heat dissipating block; a plurality of a second type of heat dissipating conduits joined to one end of the heat dissipating block, and communicating with the holding room; a plurality of guiding tubes having opposing first and second ends, the guiding tubes being connected to and communicating with the first type and the second type of heat dissipating conduits at two ends thereof wherein each of said guiding tubes is inclined downwardly from a first end in fluid communication with a respective one of said heat dissipating conduits and a second end in fluid communication with a respective end of one of said second heat dissipating conduits to allow flow of condensed liquid into said heat dissipation block by gravity assist; a liquid contained in the holding room of the heat dissipating block; a plurality of annular heat dissipating fins having a greater diameter than the outer diameter of the guiding tube being arranged on the guiding tube; and a fan positioned adjacent the heat dissipating fins.
