PROBLEM TO BE SOLVED: To provide a cooling/heating device in which a novel structure of a switching damper is proposed and conventional problems are solved, and a thermal shock test device using the same.SOLUTION: The cooling/heating device includes: a heating part 2 for supplying heating air to a test vessel 4 which accommodates an object to be heated/cooled in a such manner that the object can be freely taken in and out; a cooling part 3 for supplying cooling air to the test vessel 4; and a switching part for switching the air supplied to the test vessel 4 between the heating air and the cooling air. The switching part includes a switching damper 16, an air cylinder 18 for driving, and a damper case 17 for housing the switching damper 16 in a movable manner. The switching damper 16 includes a pair of rectangular parallelepiped damper bodies 25, and a connection part 26 interposed between the damper bodies 25, 25. The damper case 17 has a plurality of openings 301 to 306 and 401 to 406 communicating with the exterior of the damper case 17, and one or more of the plurality of openings can be closed/opened according to the position of the damper 25. A plurality of paths through which air passes are formed according to the opening/closing state of the openings. |
