Abstract:
A cooler according to an embodiment of this invention comprises a contact surface, a flow path formation unit, a supply unit, a discharge unit, and at least one retention unit. The contact surface contacts an object to be cooled. A flow path through which a refrigerant circulates is formed in the flow path formation unit. The supply unit supplies the refrigerant to the flow path. The discharge unit discharges the refrigerant from the flow path. The retention unit changes the cross-sectional area of the flow path so as to promote local retention of the refrigerant in the flow path.
