Patent ID: 8240166

Claim:
A cooling system for cooling a heat generating element, comprising, a cooling part thermally connected to the heat generating component and containing a refrigerant to be heated to its boiling by a heat energy generated by the heat generating component so that the heat energy is absorbed by the refrigerant, a heat radiator for discharging the heat energy absorbed by the refrigerant so that the refrigerant is condensed, a refrigerant driver for urging toward the cooling part the refrigerant condensed by the heat radiator, and a pipe arrangement for fluidal communication among the cooling part, heat radiator and refrigerant driver, wherein the system further comprises a heater arranged to heat the refrigerant flowing from the refrigerant driver to the cooling part, wherein the heater includes a heat controller to adjust another heat energy generated by the heater to be applied to the refrigerant in accordance with a condition of the heat generating component.
