Abstract
A coolant includes a temperature sensitive gel including a temperature sensitive polymer having hydrophilicity at a temperature lower than a lower critical solution temperature and hydrophobicity at a temperature higher than the lower critical solution temperature, and a polar solvent that wets the temperature sensitive polymer, the temperature sensitive gel undergoing a volume phase transition accompanied by an endothermic reaction in a case where a temperature rise exceeding the lower critical solution temperature occurs.
