Patent ID: 8333235

Claim:
A heat dissipation system, comprising: an evaporator including a compensation chamber and a first wick structure having a plurality of pore sizes with a relatively large pore size part, wherein the compensation chamber neighbors the relatively large pore size part for adjusting an amount of a condensate according to a dissipation power; a vapor line connected to the evaporator for transporting a vapor from the evaporator; a condenser connected to the vapor line for condensing the vapor as the condensate; and a liquid line having at one end thereof a second wick structure close to the evaporator and connected to the first wick structure, wherein the liquid line is connected to the vapor line through the evaporator and the condenser, the second wick structure is extended from only part of the way along the liquid line from the evaporator to the condenser, the condensate is transported to the evaporator through the liquid line, and the condensate in the evaporator is transformed into the vapor by an external heat source.
