PURPOSE: A cool box is an improved globe box to be used as a cool box. CONSTITUTION: A cool box(10) comprises a supplying inlet(22), an outlet(24) and a guide door(14). The supplying inlet(22) is connected with a cool air outflow line of a vaporizer(18) for the cool air to flow in. The outlet(24) is connected to a blower motor for the cool wind to stay in a globe box and flow out. The guide door(14) is installed between the supplying inlet(22) and the outlet(24) to be rotated by the driving of a motor(12). The opening angle of the guide door(14) is adjusted to extend or shorten the time the cool air stays in the cool box(10) to adjust the temperature and the cooling speed in the cool box(10).
