PROBLEM TO BE SOLVED: To provide an evaporative cooling apparatus that achieves a high evaporative cooling efficiency by promoting convection between evaporated steam resulting from the evaporation of a cooling liquid in an evaporative cooling chamber and the unevaporated cooling liquid. SOLUTION: A jacket chamber 2 is formed as an evaporative cooling chamber covering almost the entire periphery of the reaction vessel 1 serving as a cylindrical container that houses the subject of cooling. The cooling liquid is supplied to the jacket chamber 2 through a cooling liquid supply pipe 4, and the lower and upper portions of the jacket chamber 2 are connected to a combination pump 3 serving as a suction means, so as to effect the evaporative cooling of the subject of cooling. A plurality of vertical grooves 18 are formed on the outer peripheral surface of the circumferential wall 17 of the reaction vessel 1 in the jacket chamber 2 at almost regular intervals along the circumferential direction of the jacket chamber. Since the plurality of vertical grooves 18 serve as upward guide passages for the evaporated steam, the convection between the evaporated steam and the unevaporated cooling liquid is promoted to provide increased efficiency of evaporative cooling.
