Abstract
A cooling device and a motor are provided. The cooling device that cools a heating element is provided with: a cooling chamber for cooling the heating element with a first cooling medium; a radiator chamber for releasing the heat of the first cooling medium to the outside; and a first connection path and a second connection path for connecting the cooling chamber and the radiator chamber. When part of the first cooling medium in the cooling chamber is gasified, at least part of the gasified first cooling medium moves into the first connection path, thus causing a circulation in which the first cooling medium in the cooling chamber flows into the radiator chamber via the first connection path, and the first cooling medium in the radiator chamber flows into the cooling chamber via the second connection path.
