Wind direction feather displacement means for changing the plurality of wind direction feathers at the same rotation angle is provided, and the wind direction feather displacement means is operated from outside the shelf in a state where the shelves are stacked up and down. Thus, it is characterized in that the rotation angle of each of the wind direction wings is changed. According to the present invention, even when the calorific value or the temperature characteristic is changed by the device unit mounted in the shelf, the wind wing displacement means changes the wind direction angle by simultaneously and arbitrarily changing the rotation angle of each wind wing, By setting the exhaust direction, a necessary cooling air can be obtained to create a temperature environment suitable for the device unit, so that the same shelf can be used.
