COOLING DEVICE

摘要

PROBLEM TO BE SOLVED: To perform switching of a cooling system between a forced convection cooling system and a jet flow cooling system according to heating status of a heating element. SOLUTION: The cooling device which cools a heating element includes: a forced convection cooling means which cools the heating element by forced convection; a jet flow cooling means which cools the heating element by jet flow; a cooling status switching means which changes between a forced convection cooling status by the forced convection cooling means and a jet flow cooling status by the jet flow cooling means; and a heating status detection means to detect or presume heating status of the heating element, and is characterized in that the cooling status switching means performs the switching according to heating status of the heating element based on the detection or presumed result of the heating status detection means.
