PROBLEM TO BE SOLVED: To provide a cooling chamber, capable of stably and efficiently evaporating drain water over a long period with minimized energy and without using a device needing much energy for drive, and preventing collection of moisture on the back part and side part of the cooling chamber. SOLUTION: The cooling chamber A comprises a Stirling refrigerator 2, a heater exchanger 4, a U-turn air duct 5 continuously formed extending over a bottom part 1A and a back part 1B so as to introduce/derive outside air to and from the heat exchanger 4, and having a suction port 51 and an exhaust port 57 at a front portion, and a drain water evaporator 7 disposed in a bottom exhaust passage 56 of the U-turn air duct.
