PROBLEM TO BE SOLVED: To obtain a method and apparatus for cooling a work to be soldered, whereby the work can be cooled quickly. SOLUTION: An ultrasonic atomizer 12 is provided for feeding finely atomized mist to a work to be soldered, immediately after soldering. The atomizer 12 has an ultrasonic oscillator 15 disposed at the bottom of a liq. tank 13 for finely atomizing a liq. 18 in the liq. tank 13. The liq. 18 uses demineralized water. The liq. temp. in the tank 13 is held at a set temp. by a thermo module 16 disposed at the lower side of the tank 13. A gas barrier forming piping 31, for forming a gas barrier over the entire circumstance of the tank 13, is disposed on the inner side surface of the tank 13.
