Abstract
An electronic equipment includes a cooling system using boiling and condensation of a refrigerant, especially stabilizes the cooling performance, and reduces the influence which vibration accompanying phase change of boiling and condensation gives to the electronic equipment. Electronic equipment includes a cooling system including a cooling part which cools heat generating from a heat generator such as a heat generating component by using boiling of a refrigerant and is thermally connected to the heat generator such as the heat generating element, a heat radiation part which radiates heat absorbed by the refrigerant in the cooling part by condensation, a refrigerant drive part for delivering the condensed refrigerant to the cooling part again, and piping which fluidly connects them, and the electronic equipment includes preliminary heating means for heating the refrigerant, which flows to the cooling part from the refrigerant drive part, between the refrigerant drive part and the cooling part.
