Abstract
A cooling device includes a vessel having a refrigerant sealed inside, an evaporator that receives heat to evaporate a liquid phase of the refrigerant inside the vessel, a condenser that dissipates heat to condense a vapor phase of the refrigerant inside the vessel, a tube shaped transporter that transports the liquid-phase refrigerant inside the vessel to the evaporator by capillary action, and a gap generator that generates a gap between the transporter and the evaporator for the liquid-phase refrigerant to move from the transporter to the evaporator.
